Technical Field

The present invention relates to a holder for holding objects on a formwork panel, in particular for holding rail members on a ceiling formwork panel, wherein the holder is configured for mounting on the formwork panel and the formwork panel has two longitudinal edge supports and two transverse edge supports.

Background

Holders constructed on ceiling formwork panels for holding rail members are known. These known holders are of a rather heavy, complex construction. Thus complicating the transportation of the holder to the site of the construction site where it should be mounted on the formwork panel.

Disclosure of Invention

It is an object of the present invention to provide an improved holder for holding an object to a formwork panel.

This object is achieved by the features of claim 1.

According to the invention, a holder for holding objects on a formwork panel, in particular a holder for holding rail parts on a ceiling formwork panel, is proposed, wherein the holder is configured for mounting to the formwork panel and the formwork panel has two longitudinal edge supports and two transverse edge supports, wherein the holder has a first arm configured for engagement with the longitudinal edge supports of the formwork panel and a second arm extending transversely to the first arm, forming an angular space with the first arm, and configured for engagement with the second arm,

wherein the first arm has on its side facing the angular space a first projection for introduction into the opening of the longitudinal edge support, and the second arm has on its side facing the angular space a second projection for introduction into the opening of the transverse edge support;

wherein the holder has a moving mechanism by which the protrusion of one of the two arms can be moved in a direction toward the other of the two arms to tighten the holder.

The holder according to the invention is a relatively lightweight, simple-structured, inexpensive product. The holder according to the invention can be easily transported around at the construction site and can be very easily assembled (by one person only). To mount the retainer to the template panel, first, one of the two arms is positioned on one of the edge supports of the template panel. The other arm is then positioned on another edge support of the formwork panel, which edge support extends towards the same corner of the formwork panel as the aforementioned edge support. This may be accomplished by a pivoting movement of the holder. Alternatively, this may be done by driving a moving mechanism. The mounting of the holder is done by the moving mechanism being tightened, whereby, at least on one arm, the protrusion is pulled against the boundary of the opening into which the protrusion is introduced.

The holder according to the invention is also characterized in that: the moving mechanism is configured such that the projection of the above-mentioned one arm can be moved relative to the arm by the moving mechanism, or configured such that the arm can be moved together with the projection by the moving mechanism.

As disclosed in the preceding part of the description, the holder according to the invention may also have the following features: the projection of the arm and/or the projection of the other arm is configured as a rear engagement projection for rear engagement with an edge of the opening into which the projection is introduced. By this means the mounting process becomes particularly simple, since the rear engagement projection which has entered the rear engagement position slightly no longer enables the holder there to fall off the formwork panel, so that the holder can be held more easily until the displacement mechanism is completely tightened. Furthermore, the rear engagement projection improves the security of engagement with the associated edge support of the formwork panel.

As already disclosed in the preceding part of the description, the holder according to the invention also has the following features: at least one of the two arms has an additional projection for engagement with an associated edge support, wherein the projection of the arm and the additional projection of the arm are provided at spaced longitudinal positions of the arm as described previously. With this configuration, the moment support of the arm is achieved in the mounted state. The moment that attempts to rotate the arm relative to the designated edge support of the formwork panel can be effectively dissipated.

An additional projection can be provided for introduction into an opening of the arm, wherein the opening is at the same time the opening of the arm as described above or another opening of the arm. If the opening is at the same time an opening as described above, the opening must have such a length that both the projection as described above and the additional projection can be introduced into the opening. It is noted that there are also other possibilities of generating a moment support. In one embodiment of the invention, the additional projection is a projection which abuts against the lower edge of the associated edge support.

As already disclosed in the preceding part of the description, the holder according to the invention also has the following features: the first projection and/or the second projection has, on the side of its (or their) free end facing away from the associated arm, an area which at least roughly matches that part of the boundary of the opening into which the projection should be introduced. In this way, the surface pressure between the relevant projection and the boundary of the opening into which the projection should be introduced can be reduced. This also reduces wear at that location. This region may be rounded and the opposite region of the opening may be rounded.

There are some embodiments of such a holder in which the moving mechanism is a threaded mechanism or a wedge mechanism. These mechanisms are inexpensive and easy for the worker to operate. A specific movement mechanism of this type will be shown and described in the example section of the description below.

As already disclosed in the preceding part of the description, the holder according to the invention also has the following features: the arm, which is movable by the moving mechanism, is connected with the rest of the holder by means of an inclined surface guide in such a way that: so that pulling of the moving mechanism also forces the arm to move in a direction transverse to the longitudinal extension of the arm. In this way, when the moving mechanism is pulled, the protrusions of both arms as described above are automatically pulled in a direction towards the angular point of the holder. Thereby making the mounting of the holder particularly convenient, especially if both of the protrusions are configured as rear engaging protrusions.

The first and second arms may be tubular, preferably square tubular, over a substantial part of their length.

The holder according to the invention may have an integrated newel post or have means for mounting a newel post. Whereby the balustrade can be mounted to the ceiling formwork panel in a very simple manner.

Another object of the present invention is a balustrade assembly for a ceiling form panel, the balustrade assembly having the following features: the balustrade assembly has at least one balustrade holder as disclosed in the preceding part of the description, and a plurality of overlapping security elements having a longitudinal extension. The railing beams, the intermediate beams and the so-called peripheral fenders are referred to as special safety elements, see the examples below. The railing assembly may have a plurality of railing holders according to the invention, wherein in most cases the securing element spans at least the distance between two adjacent railing holders.

The balustrade assembly according to the present invention is also characterized in that: at least one balustrade holder has a tubular member into which a portion of the length of the balustrade post is inserted, and at least a portion of the number of safety elements is retained on the balustrade post. In this way, the holder according to the invention makes the assembly of the railing very convenient on the one hand, and on the other hand, still maintains a lightweight, easy-to-manage product.

A typical field of application for the holder according to the invention is the fixing of balustrades along the edges of ceiling formworks. After the concrete ceiling to be cast has been driven in (i.e., the ceiling form panels for the ceiling have been installed on the form supports), it is often necessary to install rails along the edges of the ceiling form so that personnel working on the ceiling form (e.g., when installing reinforcing steel mesh) can work without danger. However, the holder according to the invention may also be used for other purposes. It may be mentioned as an example that rotatable guide rollers for the pull cord are held on the formwork panel corners. The now upwardly turned pull rope can then be used to pull up a bucket filled with mortar, for example, to the higher level of the building under construction. Another example is a tarpaulin as a wind guard that is kept hanging vertically from the edge of the building.

Another object of the present invention is an assembly having a formwork panel, the formwork panel having two longitudinal edge supports and two transverse edge supports,

has the following characteristics: the assembly also has a retainer as described in the preceding section of the specification mounted on the assembly.

The formwork panels mentioned in connection with the invention may be formwork panels for casting concrete. However, the term "formwork panel" shall also include other formwork panels, such as formwork panels for supporting an earth embankment, and formwork panels for supporting a service work area below the ceiling of a building.

Detailed Description

When used hereinafter "under.. and" over.. it is referred to the spatial position of the two arms of the holder in a horizontal plane.

The holder 2 shown in fig. 1 has a first arm 4 (which extends in a direction from the upper left to the lower right in fig. 1) and a second arm 6 (which extends in a direction from the lower left to the upper right in fig. 1). The second arm 6 is arranged laterally with one of its end faces in the end region of the first arm 4, so that the two arms 4 and 6 form two sides of a right angle and an angular space 8 is formed between the two arms 4 and 6. The area where the two arms 4 and 6 meet together is called the apex 10.

The holder 2 also has a balustrade holder 12 arranged at right angles to the common plane of the first arm 4 and the second arm 6. The end face of the first arm 4 on the vertex side abuts against the side face 14 of the balustrade holder 12 in the lower end region of the balustrade holder 12 in fig. 1. The end region of the outer side surface 29 of the second arm 6 (i.e. the side surface facing away from the angular space 8) also abuts the side surface 14 of the balustrade holder 12. For each of the three components 4, 6, 12, the main part is designed as a square tube of steel with rounded corners. The cross-sectional shapes of the three parts 4, 6, 12 are slightly different from each other. The first arm 4 and the second arm 6 have rectangular cross sections which are slightly different from each other, the height 16 of the rectangular cross sections being slightly larger than the width 18 of the rectangular cross sections. For the balustrade holder 12, its cross-section is square with rounded corners.

The three parts 4, 6, 12 are welded to each other to form a stable unit. If the holder 2 is placed on a horizontal bottom surface with the bottom sides 20 and 22 of the two arms 4 and 6 and with the lower end surface 22 of the balustrade holder 12, the two bottom sides 20 and the lower end surface 22 are located in the same plane.

The second arm 6 has in the region of its free end 32 on its side 28 facing the angular space 8 (i.e. the distal end with respect to the apex 10) a second projection 36 which projects with respect to the remainder of the second arm 6. The second protrusion 36 is part of a generally angled element 37, the generally angled element 37 being separately manufactured and then welded to the second arm 6. On the second projection 36, a first region 40 can be distinguished next to the side surface 28 of the second arm 6 and a second region 42 spaced apart from the side surface 28 of the second arm 6. The first region 40 has the shape of a substantially semicircular plate, the peripheral edge surface 44 of which is substantially rounded to a semicircle on the side towards the apex 10 or the side facing away from the free end 32. The second region 42 is also plate-shaped, parallel to the side surface 28 of the second arm 6 over a part of its length measured in the longitudinal direction of the second arm 6, wherein the clear distance between the second region 42 and the side surface 28 of the second arm 6 corresponds to the thickness of the plate-shaped first region 40. The second region 42 projects with its end region 43 directed towards the apex 10 beyond the first region 40 of the projection 36 so that the second region 42 can engage behind with this end region a portion of the boundary of the opening in the edge support of the formwork panel, as will be described in more detail further below. The end region 43 is arranged slightly obliquely with respect to the side surface 28 of the second arm 6, so that at the end of the end region 43 the clear distance to the side surface 28 is slightly greater than the thickness of the first region.

In the region of the free end 30 of the first arm 4 (i.e. the end remote from the apex 10) there is provided a first projection 34, which first projection 34 is configured substantially similarly to the second projection 36 already described, also with a first region 40, a second region 42 and an end region 43. The first projection 34 is also part of a separately manufactured element 35, but the separately manufactured element 35 is not welded at the free end 30 with the first arm 4, the element 35 more precisely being a separate component which is fitted to move in the longitudinal direction of the first arm 4 relative to the first arm 4. To this end, a guide, not clearly visible in fig. 1, is provided between the first arm 4 and the element 35. The element 35 has a right-angled region 46, which right-angled region 46 extends in a plate-like manner transversely to the longitudinal extension of the first arm 4. A threaded rod 50 is fixed to this region 46, which threaded rod 50 extends through the hollow first arm 4 according to its length. Only the rightmost end of the threaded rod 50, which is fixed to the region 46 of the first projection 34, can be seen in fig. 1; the other end can be seen at the leftmost side. The threaded rod 50 passes through the balustrade holder 12 in two holes. On the side 15 of the balustrade holder 12 facing away from the free end 30 of the first arm 4, a manually rotatable nut 52 is screwed onto the screw 50. The nut 52 bears with its one end face against the side face 15 of the balustrade holder 12. By turning the nut 52, the screw 50 and therewith the first protrusion 34 may thereby be moved in the longitudinal direction of the first arm.

Furthermore, it can be seen in fig. 1 that the first arm 4 has a first additional projection 54 on its inner side 26 facing the angle space 8 and the second arm 6 has a second additional projection 56 on its inner side 28 facing the angle space 8. Two additional tabs 54 and 56 are welded to the inner side 26 or 28, respectively, and have the shape of an upstanding rectangular plate. The first additional projection 54 is located at a position between the apex 10 and the free end 30 of the first arm 4. The second additional projection 56 is located at a position between the apex 10 and the free end 32 of the second arm 6.

In fig. 6 and 7, the holder 2 of fig. 1 can be seen after being mounted on a formwork panel 60 (in this case, a ceiling formwork panel). To better see the details of the installation, the formwork panel 60 is shown without its formwork shell. The formwork shell side of the frame 82 of the formwork panel 60 is facing upwards in fig. 6 and 7. The formwork shell mounted on the frame 82 will completely cover the "interior" of the formwork panel 60.

For the sake of conciseness and readability, only "panel 60" is used below in place of "template panel 60".

In fig. 6 and 7, a holder 2 according to the invention is shown in the following state, namely: in this state, a portion of the length of the balustrade post 62 is telescopically inserted into the balustrade holder 12 from above. The balustrade post 62 has a hollow square cross-section that is slightly smaller than the hollow square cross-section of the balustrade holder 12.

The frame 82 of the panel 60 is essentially comprised of two longitudinal edge supports 64, two transverse edge supports 66 and several transverse intermediate supports 68. These parts are welded to each other.

In fig. 6, the direction of observation of the observer towards fig. 7 is shown by the arrow 69.

At a distance from each frame corner 80, each longitudinal edge support 64 has an elongated opening 70 through the longitudinal edge support 64. Each lateral edge support 66 also has an elongated opening 72 through the lateral edge support 64 at a distance from each frame corner 80. More specifically, the openings 70 and 72 are located in the web of the associated edge support 64 or 66, respectively, at a height between the front widening of the template shell side of the associated edge support 64 or 66 and the rear widening of the associated edge support 64 or 66. The openings 70 and 72 have the same shape. Such a shape may be described as being bounded by a generally straight line in the lower region of fig. 6, by a large radius in the upper region of fig. 6, and by a substantially semi-circle in the region between the lower region of fig. 6 and the upper region of fig. 6, which is a longitudinal end of an opening 70 or 72.

In fig. 7 it can be seen that in the mounted state of the holder 2 shown, each projection 34 and 36 is located partly in the associated opening 70 or 72 and partly engages behind the rear engagement area 43 with the boundary of the opening. In each projection 34 and 36, the rounded edge surface 44 abuts against a rounded boundary surface of the associated opening 70 or 72 in the end region of the opening 70 or 72. The fillet radius of the first region 40 of the associated projection 34 or 36 and the fillet radius of the open end region are substantially the same.

It can also be seen in fig. 7 that in the region between the respectively described opening 70 or 72 and a corner 80 of a frame 82 of the panel 60, an additional opening 74 or 76 is provided on the side wall 26 or 28, not only for the associated longitudinal edge support 64, but also for the associated transverse edge support 66. Each additional opening 74 and 76 has the shape of an ellipse that is straight in the center region and bounded by semi-circles at both ends. The first additional projection 54 of the first arm 4 is located in the additional opening 74; the second additional projection 56 of the second arm 6 is located in the additional opening 76. The additional openings 74 and 76 are identically configured and have a height only slightly greater than the height of the additional projections 54 and 56, such that the additional projections 54 and 56 fit within the additional openings 74 and 76 with little clearance in height.

It can also be seen that the two arms 4 and 6 bear with their inner faces 26 and 28 flat against the outer face of the web 78 of the relevant edge support 64 or 66. The holder 2 is thereby very firmly held on the panel 60 on the one hand, and on the other hand the holder 2 reinforces the panel 60 on the corner region where the panel 60 is mounted.

To mount the holder 2 on the corner region of the panel 60, the first projection 34 of the first arm 4 is first "removed" by moving the screw 50 in a direction away from the apex 10. The second arm 6 is then moved together with the second projection 36 onto the lateral edge support 66 in an inclined position, i.e. a position in which the apex 10 is at a distance from the corner 80 of the frame 82 of the panel 60. The second tab 36 is inserted into the opening 72 such that the second region 42 of the second tab 36 enters a position inboard of the web 78 of the transverse edge support 66. At this time, the second arm 6 is pushed in the longitudinal direction of the second arm 6 or in the longitudinal direction of the lateral edge support 66, and at the same time, the apex 10 is pivotally moved toward the corner 80 of the frame 82 of the panel 60. Wherein the additional protrusion 56 enters the additional opening 76. The rear engagement region 43 of the second projection 36 is now located inside the material of the web 78 in the vicinity of the opening 72, as shown in figure 7.

During movement of the apex 10 to the corner 80 of the frame 82, the first projection 34 and the additional projection 54 enter the openings 70 and 74 of the longitudinal edge support 64. At this point, the nut 52 is tightened and thereby pulls the first projection 34 in a direction toward the apex 10. The end region 43 of the second region 42 of the first projection 34 enters the rear engagement position shown in fig. 7, in which the end region 43 is brought into rear engagement with the boundary of the opening 70 in the region closest to the corner 80. The nut 52 is tightened. At this time, the rounded edge surface 44 of the first projection 34 also abuts against the end region of the profile of the opening 70 closest to the corner 80.

The additional projections 54 and 56 together with the first projection 34 and the second projection 36 create a moment bearing on the two arms 4 and 6. If a force is applied, for example at the upper end of the balustrade holder 12 in fig. 7, toward the front right, parallel to the longitudinal extension of the lateral edge support 66, this moment will be dissipated by the pair of projections 36 and 56. Accordingly, the same applies to the pair of projections 34 and 54 if, for example, a force is exerted on the end of the balustrade holder 12 in fig. 7 toward the right rear, parallel to the longitudinal extension of the longitudinal edge support 64.

Instead of the embodiment of fig. 1, 6 and 7, the arms 4 and 6 can be slightly longer, and the additional projections 54 and 56 can be formed and placed in such a way that, in the mounted state of the holder 2, they enter the same openings 70 or 72, respectively, as the first region 40 of the projection 34 or 36, respectively, but they are located slightly further away from the apex 10. The described torque support is also achieved by this embodiment.

It should be emphasized that the additional protrusions 54 and 56 do not necessarily have to be provided. After all, it can be said that the first arm 4 and the second arm 6 are captured between the upper and lower widened portions of the edge supports 64 and 66. Furthermore, the balustrade holder 12 abuts against the associated lateral edge support 66 for the height of the frame 82. Thus, only one of the additional protrusions 54 and 56 may be omitted, or both of the additional protrusions 54 and 56 may be omitted.

Furthermore, it should be emphasized that in this embodiment of the holder 2, the first 34 and/or second 36 protrusions may be configured without the rear engagement area 43. In this case, the first region 40 can be formed somewhat thicker than in fig. 1, 6 and 7, with the other geometries remaining unchanged. The first region 40 is again part of the element 35 or 37 as previously described.

For example, if only the first projecting portion 34 has the rear engagement area 43 and the second projecting portion 36 is configured not to have the rear engagement area 43, then, when mounting the holder 2 to the panel 60, an operation such as: as described above, the first projecting portion 34 is "removed". The first arm 4 is placed on the outside of the edge support 64 or 66 with the first tab 34 entering the opening 70 and the additional tab 54 entering the opening 74. In this stage, the second arm 6 is in a position parallel to the other edge support 66 or 64, wherein, however, the inner side 28 of the second arm 6 is still at a distance from the web 78 of the other edge support 66 or 64 of at least the thickness of the second projection 36 and the thickness of the additional projection 56 (because, otherwise, the first arm 4 cannot be mounted at all to the outer side of the edge support 64 or 66). At this time, by the moving mechanism (the screw 50 and the nut 52), the first projecting portion 34 is moved in the direction toward the second arm 6 or in the direction toward the apex 10 until the first region 40 of the first projecting portion 34 abuts against the region near the apex of the opening boundary, and the rear engagement region 43 of the first projecting portion 34 enters the rear engagement position. By this driving of the moving mechanism, the second arm 6 is simultaneously pulled toward the other edge support 66 or 64, wherein the protrusions 36 and 56 of the second arm 6 enter the openings 72 and 76.

If both the first and second protrusions 34, 36 are configured without the rear engagement region 43, the retainer 2 can be mounted to the panel 60 in the same manner as described in the preceding paragraph.

Instead of the moving mechanism in the form of a screw 50 and a nut 52 as shown in fig. 1, a wedge mechanism may be provided, for example. In this case, the rod 50 does not have a thread, but rather has an elongated hole through the rod 50 in the region to the left behind the balustrade holder 12 in fig. 1, the longitudinal direction of which hole coincides with the longitudinal extension of the rod 50. A wedge can be inserted into the elongated hole, and by driving in the wedge, the rod 50 is pulled toward the upper left in fig. 1.

In the embodiment of fig. 2 and 3, an inclined surface guide 84 is provided in the region of the apex 10. The inclined surface guide 84 has a first inclined surface 88 on an element 86 extending from the upper left to the lower right in fig. 3, wherein the element 86 is mounted in the end region on the vertex side of the second arm 6 on the outer side 29 of the second arm 6. The first arm 4 has a second inclined surface 90 which interacts with the first inclined surface 88, which second inclined surface 90 bears planarly against the first inclined surface 88 and also extends from the upper left to the lower right in fig. 3. In particular, each of the two inclined surfaces 88 and 90 consists of two partially inclined surfaces, that is to say, partially inclined surfaces on each of the upper and lower walls of the element 86 or of the first arm 4.

Unlike fig. 1, a balustrade holder 12 is fixed to the second arm 6 at a distance from the apex 10. Furthermore, the second arm 6 does not have an additional projection 56.

In the embodiment of fig. 2 and 3, the first projection 34 is firmly welded to the free end 30 of the first arm 4 and the second projection 36 is also firmly welded to the free end 32 of the second arm 6. The configuration of the two projections 34 and 36 with the first region 40, the second region 42, the rounded edge surface 44 and the rear engagement function of the projections 34 and 36 is the same as in the embodiment of fig. 1. Correspondingly, the same is true for the additional projection 54 on the first arm 4, wherein it must then be taken into account that the additional projection 54 measured in the longitudinal direction of the first arm 4 must be sufficiently short, or that the opening 74 measured in the same direction must be sufficiently long, so that when the first arm 4 is moved in its longitudinal direction towards the apex 10, the additional projection 54 has a sufficient freedom of movement in the opening 74 upon tightening of the holder 2.

In the embodiment of fig. 2 and 3, the screw 50 is not directly connected with the first projection 34, but is attached inside the first arm 4. By tightening the nut 52, the first arm 4 is thereby moved together with the first projection 34 in a direction towards the apex 10 or in a direction towards the second arm 6.

With the inclined surface guide 84 shown and described, a movement of the arm 4 in the longitudinal direction of the second arm 6 or transversely to the longitudinal extension of the first arm 4 is necessarily accompanied by a longitudinal movement of the first arm 4. By tightening the nut 52, not only the first projecting portion 34 but also the second projecting portion 36 is caused to move in the direction toward the apex 10. Therefore, it is easier to mount the holder 2 to the panel 60.

Typically, the uninstalled inclined surface guide 84 in fig. 3 is located behind the enclosing element 91 shown in fig. 2. The surrounding element 91 is firmly welded to the second arm 6 and to the element 86; this enclosing element 91 protects the inclined surface guide 84, guides the first arm 4 during longitudinal movement of the first arm 4 and establishes a rigid connection between the first arm 4 and the second arm 6.

In the embodiment of fig. 4 and 5, a wedge mechanism is provided as the moving mechanism. The wedge 94 passes through a pair of elongated holes 96 provided in the two vertical walls 26 and 27 of the first arm 4. In this embodiment, a ramp guide 92 is also provided, this time between the end face on the vertex side of the second arm 6 and the region of the first arm 4 in the region of the vertex 10. Both the first inclined surface 100 of the inclined surface guide 92 on the second arm 6 and the second inclined surface 102 of the inclined surface guide 92 on the first arm 4 extend substantially from left to right in fig. 5. More specifically, here each of the inclined surfaces 100 and 102 is composed of two partial inclined surfaces, as in the embodiment of fig. 2 and 3.

The wedge 94 has a first edge 104, which first edge 104 for a part of the length abuts against the outer side 29 of the second arm 6. The wedge 94 also has a second edge 106 extending obliquely relative thereto, the second edge 106 interacting with the left front ends of the pair of elongated holes 96. When the wedge 94 is further wedged into the pair of long holes 96 in the upper left direction in fig. 5, the first arm 4 moves in the direction toward the apex 10; this movement is necessarily accompanied by a movement of the first arm 4 transverse to its longitudinal extension.

The exemplary embodiment of fig. 4 and 5 also has a surrounding element 108, which surrounding element 108 is U-shaped in this case. The surrounding element 108 is firmly welded to the first arm 4, protecting the inclined surface guide 92, which acts as a guide for the first arm 4 during its combined longitudinal and transverse movement and forms a rigid connection between the first arm 4 and the second arm 6 allowing relative movement.

The construction of the holder 2 of the two exemplary embodiments is identical, except for the differences between the embodiment of fig. 2 and 3 and the embodiment of fig. 4 and 5 described previously.

In fig. 8 the appearance of a balustrade 110 is shown, which balustrade 110 is mounted by a holder 2 according to the invention to an edge 114 of a ceiling formwork 112 extending around a 90 ° corner 120. The corner region of the illustrated ceiling form 112 has ten ceiling form panels 60, each ceiling form panel 60 having a top dimension of, for example, 2m x 1 m. The outer sides of the five lateral edge supports 66 of the five panels 60 are visible on a portion 116 of the edge 114 of the ceiling form 112 that extends from top left to bottom right in fig. 8. On the portion 118 of the edge 114 of the ceiling form 112 extending from the lower left to the upper right, two longitudinal edge supports 64 of two panels 60 are visible. At the corner 120 of the ceiling formwork 112, i.e. the corner 80 where the panel 60 is located, the first holder 2 is mounted in the manner described in connection with fig. 1. Longitudinally to the left edge portion 116, further holders 2 are mounted, which further holders 2 are mounted on the panel 60, respectively, at a distance of two panel widths from each other. At the right edge portion 118, other holders 2 are also mounted on the panel 60 at a distance of one panel length from each other. It can be seen that the holder 2 is positioned outwardly of the associated ceiling formwork edge 114 by one of the two arms 4 and 6, respectively, but into the space between two adjacent panels 60, specifically between the webs 78 of two adjacent longitudinal edge supports 64, or into the space between the webs 78 of two adjacent transverse edge supports 66, by the other arm, respectively, in addition to being on the ceiling formwork corner 120.

In fig. 8 is shown a holder 2 according to the structure of fig. 4 and 5. Alternatively, a holder 2 according to the structure of fig. 1 or according to the structures of fig. 2, 3 may be used.

In fig. 8 it can be seen that the illustrated portion of the balustrade 110 has four sections, each section being located between two adjacent holders 2 or balustrade posts 62. In each section, four securing elements with a longitudinal extension are held in an overlapping manner on the balustrade holder 12 or on the balustrade post 62, wherein each securing element is held in its end region on two adjacent balustrade holders 12 or on the balustrade posts 62, except for its section immediately behind the ceiling formwork corner 120. To retain these fuse elements, an angular retainer 122 (see fig. 6 and 7) is typically used.

As a securing element with a longitudinal extension, the lowermost portion of each section of the balustrade 110 is provided with a peripheral barrier 124 in an overlapping manner, a balustrade cross-beam 126 in an overlapping manner at the uppermost portion, and two intermediate cross-beams 128, 130 between the peripheral barrier 124 and the balustrade cross-beam 126 in an overlapping manner.
