Technical Field

The present invention relates to a support beam for a panel system (slab system) as according to the preamble of claim 1. Such support beams are often used in the construction industry, in particular in the construction of slab systems or floors, in particular as support structures for slabs and auxiliary joists of reinforced concrete constructions or composite constructions also with other materials. The support beams may comprise a portion of the steel section that is typically filled with concrete, wherein the concrete is often reinforced by reinforcements in the form of reinforcement cages.

Background

For example, WO 2017/037106 a1 discloses a composite designed support beam for a composite designed panel system comprising at least partly concrete with supports, in particular steel supports, comprising a base plate and at least one, preferably two, webs arranged at an angle, preferably vertically, characterized in that the space defined by the web(s) and the base plate is at least partly filled with concrete, which is preferably not cast-in-place concrete.

The production of such a support can be complex and costly.

Disclosure of Invention

It is therefore an object of the present invention to simplify a support beam using a simple construction, in particular in terms of its production, composition and/or effect.

This object is achieved by a support beam according to claim 1. The support beam is intended for a panel system, wherein the support beam is preferably of composite design and/or the panel system may be of composite design. In particular, a support beam may be understood as a prefabricated composite beam which is itself capable of bearing loads and comprises, for example, steel and (steel) concrete. Such support beams may also form (other) composites with the plate elements or plates, whereby a uniform plate structure is achieved in the composite construction.

The support beam extends in the longitudinal direction and has a support, preferably a steel support, extending in the longitudinal direction. The invention is characterized in that the support is formed in at least two pieces and has at least two support parts each extending in the longitudinal direction.

The invention is based on the idea of dividing the support, in particular into two or more pieces. The fact that the support is divided can preferably be seen when viewed in a cross-section perpendicular to the longitudinal direction. Preferably, there is a spacing between the individual support members in the transverse direction of the support beam.

"divided" refers in particular to the fact that the support is divided into or formed by a plurality of pieces, when viewed in a cross section over the length of the support or in a cross section perpendicular to the longitudinal direction. "division" may relate to a division with respect to an extension in a lateral direction (i.e. perpendicular to the longitudinal direction). The lateral direction includes a lateral direction or a horizontal direction (in this case, represented by an X direction extending from left to right) extending perpendicular to the longitudinal direction, and a vertical direction (in this case, represented by a Y direction extending from top to bottom).

A divided bearing or multi-part bearing is to be understood in particular as a bearing formed from a plurality of parts. The support members do not form an integral, continuous support member.

In other words, the support is discontinuous. Thus, the support members in the support beam may be well surrounded by concrete or the like, which joins the individual support members to the support beam, wherein the support itself is still considered to be formed of a plurality of pieces.

Thus, the support member may be inserted so as to be flush with the plate. In this connection, the support plate and the bottom chord may additionally be used in the same plane in the vertical direction to achieve a reliable fit and visual uniformity.

It is also conceivable that the support parts are held together by an element also made of steel and can be considered as another support part. Such an element or a plurality of such elements results in an engagement of the support part parts, in particular in the longitudinal direction. In which case the support is still formed from a plurality of pieces.

The two-part or multi-part form of the support refers to the fact that: the support is produced from at least two or more parts/pieces.

The support may also be referred to as the steel section of the support beam. Preferably, one embodiment of the invention may be described as follows: the cross-section at the end may comprise more than one partial cross-section, or the support beam may comprise more than one part to form the end cross-section. These components can be produced separately and subsequently assembled to form a unit and then appear in the cross section of the support beam.

These elements, which are parts of the support, are preferably composed of steel. Thus, the support is a steel support. The support described herein is in particular a component part, usually consisting of steel plate or rolled steel, which usually at least partially serves as a formwork for the concrete of the support beam when the support beam is filled with concrete. The steel plate may be smooth, edged and/or welded.

The multipart form of the support is evident from the fact that: the support comprises at least two support members each extending in said longitudinal direction. Preferably, the support members may be arranged substantially parallel to each other and in the same position in the longitudinal direction. In other words, the support members may extend substantially side by side.

The parts of the support preferably extend side by side and none behind the other in the longitudinal direction. Due to the fact that the two support members extend side by side, the multipart form is shown in particular in a sectional view in a transverse direction perpendicular to the longitudinal direction. In this way, the multipart form of the bearing can be shown in particular in a sectional view perpendicular to the longitudinal direction.

The multipart form of the bearing is particularly evident in cross section (i.e. with respect to the transverse direction). Preferably, the support parts extend parallel to each other in the longitudinal direction, so that the support parts are not only aligned in the longitudinal direction. The same applies to the base plate if the multipart form of the support (among other things possible) is realized as a multipart form of the base plate or of other parts of the support. Preferably, there is a spacing between the individual substrate parts in the transverse direction of the support beam. Not only the substrate may be formed of a plurality of members spaced apart in the lateral direction, but also a space may be formed between the substrate (including a plurality of substrate members) and other support members in the X direction.

Preferably, the at least two support members are arranged spaced apart from each other in a transverse direction extending perpendicular to the longitudinal direction. In other words, there may thus be a space between the support members extending in the transverse direction.

It is common in the construction industry to reinforce concrete sections using reinforcement cages (reinforcement cages) including stirrups and longitudinals inside the concrete section of a support beam. However, in particular, the support described herein is not to be understood as such a reinforcement cage or reinforcement or the like. The connecting means are not considered to be a support.

As will be known to those skilled in the construction industry, a "reinforcement cage" or "reinforcement cage" is generally understood to be a reinforcement for a concrete component, which helps to increase the capacity to bear loads and improve the absorption of any forces that may occur.

In this respect, the reinforcement cage comprises a plurality of reinforcement bars (reinforcement bars) arranged side by side, for example in the transverse direction of the support beam, which reinforcement bars extend in turn along the longitudinal direction of the support beam and are arranged, for example, one above the other in the vertical direction. This arrangement of reinforcement is surrounded by a stirrup or the stirrup contains the longitudinal bar. The stirrups provide lateral reinforcement and are generally rods that are bent in a manner that is each substantially self-contained. A plurality of stirrups surround the reinforcing bars at regular intervals in the longitudinal direction of the support beam. In other words, the stirrups are arranged at repeated intervals in the longitudinal direction. Thus, a cage is formed by the stirrups and the longitudinal bars, which facilitates corresponding longitudinal and transverse reinforcement.

Such a reinforcement cage may be used as a loose or loose element between the support parts of the support beam and may be cast with concrete to reinforce the support beam.

One advantage of the present invention is that the support members can be used for various support beams, in particular for support beams of different widths or heights, since the spacing between the support members in the transverse direction can be set individually depending on the desired width or height of the support beam. For example, the same support members may be used for relatively narrow support beams as for relatively wide support beams, and thus the narrow support beams and the wide support beams differ substantially only in the spacing between the support members. In the case of narrow support beams, there may be a relatively small spacing between the support members in the lateral direction. This means that prefabricated support parts, in particular of similar type, can be used universally to form various support beams.

Another advantage is that material for the support can be saved if there are support members spaced apart from each other instead of a continuous support. This also results in more cost effective manufacture.

Preferably, the support has a base plate. The substrate may be formed in at least two pieces or a plurality of pieces and comprise at least two substrate parts each extending in the longitudinal direction. Separating the base plate is one possibility to realize separate supports. This design is efficient and easy to implement. Preferably, a base plate or base plate part is understood as a support part which does not protrude and/or which defines the concrete-filled region of the support beam.

In particular, the use of elements which partially connect the substrates in the longitudinal direction with the substrates separated is conceivable. These elements may be, for example, transverse webs or sheets which connect the substrate components in respective portions (portions in the longitudinal direction) perpendicular to the longitudinal direction (i.e. in the transverse direction).

The support beam may have a support comprising at least one, preferably two, angularly (preferably vertically) arranged webs. The use of a web, preferably extending from the base plate, allows for a stable construction of the support capable of withstanding loads.

The multipart form of the support can be formed in particular in the transverse direction by the multipart form of the base plate (i.e. the space between the base plate parts) and/or by the space between one and/or more webs opposite each other and/or in connection with the base plate.

The support beam is preferably a composite beam and at least partially comprises concrete, wherein the concrete is hardened, in particular during assembly at the construction site, such that it can bear loads and/or wherein the concrete (subsequently added) is not cast-in-place concrete. For example, concrete may be present in the support beam as such before the support beam is assembled in the structure. This facilitates a high load capacity of the beam and an efficient assembly process.

Finally, a particularly advantageous embodiment is conceivable, in which two base plate halves are provided, which are symmetrical to one another in the mounting support beam with respect to a plane of symmetry along the longitudinal axis. In this case, the left and right substrates may be manufactured from a continuous profile. One example of a multi-part form is the spacing of the substrate parts in the transverse direction. The substrate parts may be spaced apart from each other, e.g. in a vertical or horizontal direction, in particular when seen in a sectional view. This allows the advantages according to the invention to be easily achieved. The substrate may also be partially connected (in particular to simplify manufacturing). For example, the respective portions in the longitudinal direction may connect the substrate members in the lateral direction.

In a preferred embodiment, the support members are symmetrical to each other with respect to the longitudinal axis of the support beam. In such an embodiment, the two support members can be produced from a continuous profile, which is inexpensive. The continuous profiles may be cut in the longitudinal direction and subsequently arranged side by side, so that as a result a support part of the support beam is provided.

Preferably, the support members are arranged at the edge regions, as seen in a transverse direction extending perpendicular to the longitudinal direction, and/or the support members are spaced apart from each other in the central region, as seen in a transverse direction extending perpendicular to the longitudinal direction. As a result, the support beam is less complex to produce. In this way, the stability of the support beam in the edge regions can also be maintained, a compromise being acceptable in terms of load-bearing capacity in the central region of the support beam.

The support beam may comprise a reinforcement cage preferably comprising reinforcement bars. The reinforcement cage may comprise at least one longitudinal reinforcement and/or at least one stirrup. The concrete may at least partially (preferably completely) surround the reinforcement bars of the reinforcement cage, wherein the concrete hardens even during assembly. As a result, the stability of the support beam and the load bearing capacity of the support beam can be improved.

Preferably, the connecting means attached to the support member extend through a void in the reinforcement cage in the transverse direction. Such a connection means may facilitate a frictional connection between the support and the concrete, which increases the load carrying capacity.

Preferably, the base plate and/or the web or webs comprise one or more protruding elements or protrusions extending perpendicular to the longitudinal direction and serving to support other components. Such projecting elements project from the support beam and can support a constituent part such as a finished part or a semi-finished part. The protruding elements may also be referred to as protrusions or plate supports/carriers protruding from the rest of the support beams, in particular in the lateral direction, more particularly in the X-direction.

The base plate, in particular on its underside facing away from the support beam, and/or preferably the projection of the barrier for protection against heat and/or flames. Preferably, the protective barrier may take the form of a film-forming coating. This will prevent the support from losing its strength when heat is formed, especially in the form of a fire, which will cause the support beam to become unstable.

The invention is also achieved by a method of producing a support beam extending in a longitudinal direction. The support beam is produced with a desired extension in a transverse direction extending perpendicular to the longitudinal direction, wherein preferably the support beam according to the invention is used for a composite designed panel system. The method comprises the following steps: providing at least two support members, in particular steel support members; determining the positions of the support members relative to each other with respect to the lateral direction according to the desired extension of the support beam in the lateral direction; and arranging the support member according to the determined position and in such a way that the support member extends in the longitudinal direction.

When producing the support beam, a multi-part form, preferably a two-part form, of the support is advantageous. For example, the possibility of various arrangements is opened up, so that production can be optimized according to the time and procedure involved.

Preferably, the space between the support members in the lateral direction will be determined when determining the position of the support.

Optionally, a reinforcement cage is provided and the support member is arranged around the reinforcement cage when the support member is arranged according to the determined position, wherein the reinforcement cage is preferably in its final form during the process. By arranging and producing the support beams with reinforcement cages in this way, a significant simplification and time saving can be achieved. When using reinforcement cages at the same time, particular advantages will appear, since then parts of the support with protruding connection means, such as pins, protrusions or block shear connectors, attached on the side facing the concrete can surround the reinforcement cages, in particular they can pass through the reinforcement cages from the side. This allows the reinforcement cage to be used in its finished state during assembly and the support members can be connected together around the reinforcement cage as formwork for the support beam.

Preferably, the provision of at least two support members comprises a continuous support profile divided into at least two parts in the longitudinal direction.

Preferably, the support extending in the longitudinal direction, in particular the steel support, is formed with a lift, which can also be understood as an inclination. In particular, at least one web may have a lift. By "raised" is herein understood an arcuately curved form of the support or component extending in the longitudinal direction, wherein the "arcuation" extends opposite to the (future) load direction along the longitudinal direction of the support. This creates a "banana-shaped" extension of the support member in the longitudinal direction, which counteracts or can compensate for the load due to the concrete and the weight of the plate, for example in the vertical direction of the support beam. Such rises have a "rise height" or "pitch" and describe a measurement that indicates the distance between the bounce line and the arcuate apex of such curvature. In other words, the support member (or at least one support member, preferably at least the web) may have a pre-camber. This means that the curvature imparted by the bearing can counteract the potential deflection under load, thereby compensating for future deflections. In other words, "tilting" (raising) corresponds to a subsequent deflection of the support beam.

As a result, a homogenous and flush plate design can be achieved. These production of so-called oblique support beams can be advantageous for small deformations recognizable in the finished structure, since the deformations at the mounting of the plate elements and the bevels almost cancel each other out.

According to the invention, the intended use of the support beam according to the invention is in a panel system of composite design, wherein the support beam is used for supporting at least one semi-finished or finished component or cast-in-place concrete component or a constituent component made of other material.

Furthermore, according to the invention a composite-designed panel system is provided, wherein the panel system comprises at least one beam according to the invention, at least one component part, semi-finished component or finished component supported on the at least one support beam, and a cast-in-place concrete layer provided at least in the connection region between the at least one support beam and the component part, semi-finished component and/or finished component. The use of support beams in a panel system may ensure rapid assembly in the field.

According to the invention, a method for producing a panel system of a composite design can also be provided, having the following steps: supporting a support beam according to the invention on a carrier; supporting at least one component part, semi-finished part or finished part on at least one support beam; and providing a connecting device in a connecting region between the at least one support beam and the component part, the semi-finished part or the finished part.

Optionally, the method may also comprise the step of providing a cast-in-place concrete layer at least in the connection area between the at least one support beam and the constituent, semi-finished and/or finished component. The gaps between the components may be grouted or filled with grouting mortar or concrete.

Detailed Description

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 shows a support beam 1 according to the invention in a cross-sectional view perpendicular to the longitudinal direction L of the support beam. The support beam 1 is of composite construction, i.e. a composite of support 2 and concrete 6. The support beam 1 is intended for a plate system (not shown) which may be of composite design. The support beam 1 extends in a longitudinal direction L perpendicular to the plane of the drawing. The support 2, preferably a steel support, is formed in two pieces, wherein the two pieces (i.e. the two support parts) each extend in the longitudinal direction L and substantially parallel to each other.

Fig. 1 shows a substrate 3 formed in two pieces and comprising two substrate parts 3a and 3 b. The two substrate parts 3a and 3b extend side by side and each extend in the longitudinal direction L. The support 2 has two webs 4, 5 which extend side by side and are parallel to one another in the longitudinal direction L in this embodiment. The two webs 4, 5 are arranged perpendicular to the base plate 3. To be more specific, the web 4 is arranged perpendicular to the base member 3a, and the web 5 is arranged perpendicular to the base member 3 b.

The support beam 1 has concrete 6, which is not cast-in-place concrete, but which is hardened before assembly so that it can withstand the load. The concrete 6 is only absent in the area where the lateral reinforcement can be inserted, this area being referred to as the penetration pipe 13. In the sectional view as in fig. 1, a pipe 13 is shown through the concrete 6.

The support parts in the embodiment shown in fig. 1 are understood to be the base part 3a and the web on the one hand and the base part 3b and the web 5 on the other hand. A space a exists between the two substrate members 3a and 3b in the lateral direction Q. In the embodiment shown in fig. 1, the interval extending in the lateral direction Q is an interval in the X direction. Thus, the substrate members 3a and 3b are arranged to be spaced apart from each other in the X direction.

The two support and two base parts 3a and 3b and the webs 4, 5 are formed symmetrically to each other with respect to the longitudinal direction L, in particular with respect to the longitudinal axis L of the support beam 1. In other words, half of the support 1, viewed in the transverse direction Q, results from a reflection of the other half of the support 1 on a plane which passes through the longitudinal axis of the support beam and extends in the Y direction.

When viewed in the transverse direction, on the one hand the two support parts 3a, 4 and on the other hand the two support parts 3b, 5 are arranged in the edge region R. The space a between the two support members is located in the central area M of the support beam 1 in the embodiment shown in fig. 1.

The support beam 1 comprises a reinforcement cage 7, which in turn preferably comprises longitudinal bars 7a and stirrups 7b made of steel reinforcement. In this embodiment, the concrete 6 completely surrounds the reinforcement cage 7 made of steel reinforcement, i.e. completely surrounds the longitudinal bars 7a and the stirrups 7 b.

The support beam 1 may comprise connection means 8 that improve the connection between the support 2 and the concrete 6. The connecting means 8 are attached to the support 2 and extend in a transverse direction through the void in the reinforcement cage 7. In this way, good load bearing capacity can be achieved.

In the embodiment shown in fig. 1, the protruding elements or protrusions 9 extend from the substrate 3 or substrate parts 3a, 3 b. The projecting elements 9 are arranged on the substrate parts 3a, 3b and extend in the X-direction.

The substrate 3 may be provided integrally with the protruding element 9. In the embodiment shown in fig. 1, the base part 3a is formed integrally with the protruding element 9, and the further base part 3b is formed integrally with the protruding element 9.

Fig. 2 shows a perspective view of a support beam 1 according to the invention in combination with another assembly 10. The support beam 1 extends in the longitudinal direction L and comprises a reinforcement cage 7. In the embodiment shown in fig. 2 (and the remaining figures), neither support member or web 4, 5 is raised. The support 2 is formed in two pieces, thereby forming two base plate parts 3a and 3 b. The base part 3a is integrally connected to the protruding element 9. The assembly 10 forming the plate system rests on the projecting element 9. A space is formed between the assembly 10 and the support beam 2, which space is grouted or filled with cast-in-place concrete 11 or grouted/filled concrete.

Fig. 2 thus shows a composite-designed panel system according to the invention, which comprises, in addition to the support beam 1, a constituent, semi-finished or finished component 10, wherein a cast-in-place concrete layer 11 is filled between the support beam 1 and the constituent, semi-finished or finished component 10. The support beam 1 is thus used in a panel system of composite design, wherein the support beam 1 supports a semi-finished part, a finished part 10 or even a cast-in-place concrete part 11.

Fig. 3 shows various embodiments of the support beam of the invention in a sectional view, wherein thus substantially most of the support 2 is shown. Only fig. 3(d) and 3(f) show the support beam 1 with the bracket 2, the reinforcement cage 7 and the concrete 6.

Fig. 3(a) shows an embodiment comprising a unitary substrate 3. The base plate 3 is formed integrally with the web 5. The web 4 opposite the web 5 is spaced from the base plate 3 in the Y direction. Thus, the support 2 in the embodiment of fig. 3(a) is formed in two pieces: the support 2 comprises a first support part 4 (web 4) and a second support part formed by a base plate 3 and a web 5. The space between the base plate and the web 4 results in a multipart form of the bearing 2. Other arrangements of the web 4 relative to the base plate 3/web 5 in the transverse direction (X-direction) allow for the formation of support beams of different widths.

In the embodiment of the support 2 shown in fig. 3(b), the base plate is divided into two base plate parts 3a and 3 b. The base members are integrally connected to the webs 4, 5, respectively. As a result, the support 2 according to the embodiment of fig. 3(b) is formed in two pieces, that is, the base plate is formed in a plurality of pieces. The elements 8 on the webs 4 and 5 constitute connecting means such as moon plates with holes.

In the embodiment shown in fig. 3(c), the base plate 3 is a unitary piece, with the webs 4, 5 each being arranged spaced from the base plate 3. Thus, the embodiment of fig. 3(c) may be considered to be a multi-part form of a bearing, or more specifically a three-part form of a bearing, wherein the bearing comprises: a first part comprising a web 5, a second part comprising a web 4 and a third part comprising a base plate 3. A connection means 8 is provided on each of the webs 4, 5 and the base plate 3.

Fig. 3(d) shows an embodiment with a two-piece substrate comprising substrate parts 3a and 3 b. In addition, a protective barrier 12 is provided on the underside of the base plates 3a, 3b and the protruding elements 9, said barrier being heat and/or fire resistant. In this embodiment also the connecting means 8 are shown. A reinforcement cage 7 is also provided. The figure also shows the concrete 6, i.e. the complete support beam 1, and not only the support 2 in substance.

In the embodiment of fig. 3(e), the substrate is formed in two parts from substrate parts 3a and 3 b. Furthermore, the webs 4, 5 are each arranged spaced apart from the base part. Thus, the embodiment of fig. 3(e) can be considered as a four-piece bearing 2. Various connecting means 8 are arranged in the interior of the support beam 2. Different arrangements of the webs 4 and 5 in the X-direction or transverse direction Q relative to the base parts 3a and 3b result in support beams of different widths.

The embodiment in fig. 3(f) shows a support beam 1 having a reinforcement cage 7, concrete 6 and a three-piece support 2 comprising: a first support part comprising the projecting element 9, the base part 3c and the web 4, a second support part comprising the base part 3a, and a third support part comprising the web 5, the base part 3b and the projecting element 9. A unique feature of this embodiment includes a third base plate part 3c arranged higher to support a plate assembly (not shown) having a smaller thickness (extending in the Y-direction) on the projection 9.

In this embodiment, as well as in other embodiments, the two projecting elements 9 can be arranged at different heights, i.e. at different positions in the Y direction, for supporting the plates projecting towards opposite sides of the support beam 1. However, it is also conceivable that the projecting elements 9 are arranged at the same Y height.

The embodiment in fig. 3(g) shows a support 2 comprising two support parts, wherein one support part comprises a protruding element 9 and a web 4 and the other support part comprises a protruding element 9 and a web 5. In this embodiment, the base plate 3 is provided so as not to extend inwardly toward the concrete. The projection 9 forms the lower end of the support 2 as the base plate 3.

In the embodiment shown in fig. 3(h), there is a space between the base plate 3 and the webs 4, 5. The space between the base plate 3 and the projection 9 provides particularly good fire protection in the event of a fire from below. Since the support member is composed of three pieces (i.e., the web 4, the web 5, and the base plate 3), this embodiment can be considered to be a three-part form. The connection means 8 are provided on the web as well as on the base plate 3.

In the embodiment of fig. 3(i), a three-part form of the support is shown: the web 4 forms one part together with the projecting element 9, the base plate 3 forms the other support part and the web 5 forms the third support part. The width of the support beam 1 can be adjusted by moving the webs 4 and 5. The support members each comprise a connection means 8. A protective barrier 12 is provided on the underside of the substrate 3 and on the underside of the protruding element 9. The protruding portion 9 is raised, i.e., offset in the Y direction with respect to the substrate 3.

In the embodiment of fig. 3(j), a four-piece bearing is shown, wherein the bearing comprises: a first member including a base plate 3a and a web 4; a second part comprising a protruding element 9 on the left-hand side; a third support member including a base member 3b and a web 5; and a fourth support part comprising a protruding element 9 on the right-hand side. In this case, the projecting elements 9 may be connected to the respective web 4, 5 by connecting elements 14, such as tensioning plates, sheet metal triangles or tensioning rods. Despite this connection, there is still a multipart form of the connected support parts, which is particularly evident in sections elsewhere (in the longitudinal direction L). Thus, projecting elements 9 of different heights are easily realized.

The support beam 1 according to the invention can be produced as follows: when producing a support beam 1 extending in the longitudinal direction L, the following steps are taken to achieve a desired amount of extension in the X or Y direction (i.e. in a transverse direction extending perpendicular to the longitudinal direction), wherein the support beam 1 is preferably produced according to the invention. First, two or more support parts are provided, such as a first part comprising the protruding element 9, the base part 3a and the web 4 and a second support part comprising the protruding element 9, the base part 3b and the web 5 as shown in fig. 1.

The positions of the two support members relative to each other with respect to the transverse direction Q (in this case, the X direction) are determined by the fact that the desired amount of extension of the support beam 1 in the X direction is to be obtained. If the support beam 1 has a wide extension in the X-direction, the first support member 1 and the second support member 1 are arranged at a considerable distance a from each other. However, if the support beam 1 has a smaller extension in the X-direction, the distance a will be smaller. Subsequently, the support members are arranged according to the determined positions and the respective spacings in such a way that they extend in the longitudinal direction L. As shown in fig. 1, the support parts then extend parallel to one another and side by side in the longitudinal direction L.

The reinforcement cage 7 is made of longitudinal bars 7a and stirrups 7b of reinforcement in a previous working step. The support members are arranged around the reinforcement cage 7 according to the determined position. The connecting means 8 attached to the support member may for example pass through the reinforcement cage 7 when the support member is arranged according to the determined position. In particular, the support member is pushed laterally, i.e. in the X-direction towards the reinforcement cage 7, and the connecting means 8 protrudes into the reinforcement cage 7. In this case, the reinforcement cage 7 may already be in its final form. It is therefore not necessary to insert the reinforcement cage 7 in separate parts into the already assembled support 2; instead, the support 2 is integrated in the support beam 2, since separate support parts are arranged in and around the reinforcement cage 7.

The two symmetrical support members in the embodiment of fig. 1 may be obtained by dividing the continuous support member profile in longitudinal direction into two parts. The two components are arranged side by side in the transverse direction according to a determined position.

Once the support beam 1, including the support 2, the reinforcement cage 7 and the concrete 6, has hardened, it can be transported to a building site and used there for manufacturing a slab system. For this purpose, as shown in fig. 2, the support beam 1 is supported on a carrier (not shown), and the constituent, semi-finished or finished components 10 are in turn supported on the support beam 1. The connection means are provided in the connection area between the support beam 1 and the finished/constituent part 10. In addition, a cast-in-place concrete layer 11 may be provided at least in the connection area between the support beam 1 and the assembly 10.

In the different embodiments described above, various combinations and designs are shown in relation to support members, protruding elements or protrusions, protective barriers, connecting means, reinforcement cages etc. Of course, the embodiments that have been described in detail are given by way of example only, and several other combinations and designs are also conceivable.
