Technical Field

The present invention relates to a cable tray, and more particularly, to a cable tray which has a simple structure, reduces components, and facilitates assembly.

Background

Generally, a cable bridge is laid after electric or communication cables are arranged in construction sites such as buildings, factories or tunnels, and the conventional cable bridge is described as follows according to drawings:

as shown in fig. 1, a general cable tray (10) is generally formed in a ladder shape extending to a predetermined length, and is generally formed by first and second side rails (11,12) and side rails (11,12) spaced apart from each other by a plurality of cross bars (13) so as to form side walls having a predetermined width on both left and right sides.

In this configuration, the side rails (11,12) are not formed of a single panel but are formed by joining a plurality of side panels (14) having a predetermined length to each other by means of separate connectors (15), which not only results in a complicated manufacturing process due to the provision of the side panels (14) and the separate connectors (15), but also results in a troublesome assembly work due to the increase in the number of joints of the joint connectors (15).

In the conventional cable tray (10), the two side plates (14) are connected by point contact by the connector (15) to form a ground connection (16), and the ground connection (16) is generally made of cupronickel, which may cause a burden in terms of cost and connection work.

Disclosure of Invention

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a cable bridge which is connected by an integrated extension structure, reduces the number of components, facilitates the assembly work, and improves the connection method between the components, and which can replace the conventional structure and facilitate the manufacture.

According to a feature of the present invention, there is provided a cable tray comprising: a first and a second side rails (31,32) having side walls with a predetermined width on both left and right sides, and a plurality of cross bars (33) disposed to connect the first and second side rails (31, 32);

the first and second side rails (31,32) are composed of a plurality of side plates (34,35) and auxiliary connecting materials (36), and one end or both ends of the side plates (34,35) are provided with expansion end parts (39) which can be inserted into other side plates (34, 35);

the auxiliary connecting member (36) includes a bolt (37) coupled to each of the connecting holes (41,42), and the bolt (37) includes an electrical connecting bolt (37a) for connecting the side plates (34, 35).

According to another feature of the present invention, the bar (33) comprises a C-shaped groove auxiliary material (43) extended to a predetermined length and a bolt shaft (48) welded to both ends of the groove auxiliary material (43) to be integrally protruded by a predetermined length:

the bolt shaft (48) passes through a coupling hole (45) formed in the side plates (34,35) and is coupled to a coupling nut (49).

According to another characteristic of the invention, said cross-bar (33) is provided with hanging tabs (50) projecting for a certain length from the two ends of said cross-bar (33) to hang the tie (T) for binding the cables (C).

Effects of the invention

As described above, since the expanded end portions 39 are integrally formed at the end portions of the side plates 34,35, and the other side plates 34,35 are coupled to each other by the auxiliary coupling member 36 in a state where the other side plates 34,35 are inserted into the expanded end portions 39, it is not necessary to manufacture the conventional connector 15, and not only a compact structure can be formed, but also the number of connections can be greatly reduced compared to the conventional manner in which the side plates 34,35 are coupled one by one with the connector 15, thereby providing an advantage of convenience in assembly.

In addition, the transverse bar (33) of the invention is welded with the bolt shaft (48) on the end part of the side plate (34,35), thereby greatly reducing the trouble of operations of manufacturing the transverse bar (33) in advance and then inserting the side plate (34,35) or the connecting nut (49), and having the advantage of facilitating the assembling operation of the side plate (34,35) and the transverse bar (33).

Meanwhile, because the two ends of the transverse bar (33) are protruded to form the hanging pieces (50), the cable (C) can be stably fixed at the corner of the cable bridge (30) through the ribbon (T), and the cable bridge has the advantages of reducing dead space (D) and improving space utilization.

In addition, since the auxiliary material for connecting the side plates includes the electric connection bolt, when the side plates made of steel are connected to the ground, the side plates are connected by the electric connection bolt, so that the conventional electric connection bolt made of cupronickel can be replaced, and the advantages of convenience in cost, connection operation and the like can be provided.

Detailed Description

The above objects, features and advantages of the present invention will be further apparent from the following detailed description. The following is illustrated on the basis of drawings which show possible embodiments of the invention:

fig. 2 to 7 show a preferred embodiment of the present invention. As shown in fig. 2, the cable tray 30 of the present invention includes first and second side rails 31 and 32 and a plurality of cross bars 33 connecting the first and second side rails 31 and 32, wherein left and right sides of the first and second side rails 31 and 32 form side walls with a predetermined distance. The side rails 31,32 are formed by connecting a plurality of side plates 34,35 by a connecting auxiliary material 36, the horizontal bar 33 is a rod having a predetermined length, and both ends of the horizontal bar 33 are connected to the side rails 31, 32.

In this configuration, the side plates 34 and 35 are formed in a groove shape by upper support plates 34a and 35a and lower support plates 34b and 35b, which are formed to be folded in a horizontal direction with a constant width at upper and lower ends of a steel plate with a constant width, and a groove-shaped expanded end portion 39 with a constant area is formed at one end of the side plates 34 and 35, and when the end portions of the other side plates 34 and 35 are inserted, they are joined to each other by a coupling auxiliary material 36 composed of a bolt 37 and a nut 38. FIG. 3 illustrates the following:

as shown in fig. 3, an integral type expanded end 39 is formed by connecting one end of the side plates 34,35, and the expanded end 39 is connected by the auxiliary connecting member 36 after the partial end of the other side plate 34,35 is inserted, so that the side plates 34,35 are integrally connected to each other, thereby eliminating the conventional independent connector 15.

The side plates 34 and 35 are formed in a unit length, and a plurality of unit bridges U are formed in a unit shape to which the cross bar 33 is attached, and are connected to each other according to the installation location; the other end sides of the expanded end 39 and the expanded end 39 are formed with corresponding connection holes 41 and 42, and the connection holes 41 and 42 are formed in the form of long holes in the left-right direction or in the up-down direction, and a sufficient gap is formed in the left-right direction or in the up-down direction, so that the auxiliary connection member 36 can be inserted more easily, thereby facilitating the connection work.

In addition, as shown in fig. 4, the auxiliary connecting member 36 is composed of the bolt 37 and the nut 38 as described above, and the side plates 34 and 35 are coupled to each other, and at this time, the auxiliary connecting member 36 may connect the side plates 34 and 35 made of stainless material including the electric connecting bolt 37a and the electric connecting nut 38a made of copper, so that the grounding can be performed without the grounding wire 16, and the assembly and the manufacturing are facilitated.

As shown in fig. 5 to 7, the horizontal bar 33 is formed of a C-shaped groove auxiliary material 43 extended to a predetermined length, and a bolt shaft 48 is welded to both end portions of the groove auxiliary material 43 to protrude a predetermined length, and for this reason, a partition 44 through which the bolt shaft 48 penetrates is formed at both end portions of the groove auxiliary material 43, and the horizontal bar 33 is connected to a connection nut 49 through a connection hole 45 formed in the side plates 34, 35.

The cross bar 33 is formed by integrally manufacturing the bolt shaft 48 of the connecting member 47 in advance, and the assembling can be completed by screwing the connecting nut 49 in a state where the cross bar 33 is inserted into the side plates 34 and 35 at the assembling stage in the field or manufacturing process. In addition, after one end of the transverse bar 33 is assembled on the side plate 34 on one side, the side plate 35 on the other side is inserted into the other end of the transverse bar 35 for assembly, and the connecting nut 49 can be tightened under the condition that the interference of other structures outside the side plate 35 is reduced in the assembly process, so that convenience is brought to the operation.

The both end portions of the horizontal bar 33 are protruded to a certain length, and the hanging pieces 50 protruded to a certain length are formed at one side or both sides of the left and right sides, and are combined with separate auxiliary materials by welding for convenience of manufacturing, and the shape thereof may be manufactured in various shapes including a triangle shape, instead of being integrally bent at the time of manufacturing the partition plate 44.

According to the hanging piece 50, when the cable C is laid on the horizontal bar 33 with the cable C placed thereon and the cable C is wound around the horizontal bar 33 to be fixed, the cable C can be fixed by the cable T with both end portions of the horizontal bar 33 placed thereon, thereby reducing the occurrence of the dead space D at the corner of the cable tray 30.

Normally, the lower ends of the side plates 34 and 35 are formed with lower support plates 34b and 35b of a certain width, and the fixing of the tie T is difficult, so that the space utilization rate is lowered, and in consideration of this point, the end of the cross bar 33 is partially separated from the side plates 34 and 35 to form a space in which the tie T can be fixed, but in the case of the present invention, the cable C is positioned in the dead space D by providing the hanging piece 50, so that the space utilization rate is improved, and the cross bar 33 is completely fastened and firmly connected by the connection nut 49 in a state of being closely attached to the lower support plates 34b and 35b, thereby improving the structural stability.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications and changes may be made without departing from the technical idea of the present invention.
