Description

[Technical Field]

[0001] The present invention relates to a cable rack installation structure (cable rack installation structure). [Background technology]

[0002] Conventionally, cable racks are used for laying cables (Patent Document 1). Because the top and bottom surfaces of the cable rack are open, when the cable rack is laid outdoors, a top cover is installed over the top opening and a bottom cover is installed over the bottom opening to prevent deterioration due to ultraviolet rays and to prevent small animals from entering.

[0003] Cable racks may be installed in multiple tiers spaced apart vertically (up and down), in which case a top cover and a bottom cover must be installed for each cable rack. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Utility Model Registration No. 3014304 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the top and bottom covers are heavy, and the cable racks arranged vertically are spaced closely together, so installing the top and bottom covers on the lower cable racks requires a great deal of effort.

[0006] The present invention was made in consideration of the above circumstances, and the problem to be solved is to provide a cable rack installation structure that contributes to improved workability compared to conventional methods. [Means for solving the problem]

[0007] The cable rack installation structure of the present invention is a structure in which a plurality of cable racks are arranged at intervals in the vertical direction, locking tools are locked to the plurality of cable racks, and side covers that cover the lateral gaps generated between the plurality of cable racks are fixed to the locking tools.

Advantages of the Invention

[0008] In the present invention, a side cover that covers the lateral gaps generated between the plurality of cable racks is provided, and it is not necessary to install an upper cover or a lower cover for each cable rack, so the workability can be improved compared with the conventional method.

Embodiments for Carrying Out the Invention

[0010] (Embodiment) An example of an embodiment of the present invention will be described with reference to the drawings. Here, as an example, the case where two cable racks 10 are provided at intervals in the vertical direction is taken. For convenience of explanation, hereinafter, the upper cable rack 10 on the upper stage side may be referred to as the "upper rack 10A", and the lower cable rack 10 on the lower stage side may be referred to as the "lower rack 10B".

[0011] As an example, the cable rack installation structure shown in FIG. 1 is a structure in which a plurality of cable racks 10 are arranged at intervals in the vertical direction, locking tools 20 are locked to each of the plurality of cable racks 10, and side covers 30 that cover the lateral gaps generated between the plurality of (two in this embodiment) cable racks 10 are fixed to the locking tools 20.

[0012] The cable rack 10 of this embodiment is a member for arranging various cables such as electric wires. As an example, the cable rack 10 shown in FIG. 1 is a ladder-shaped member including a parent girder member 11 arranged in parallel with a gap therebetween and a child girder member 12 installed in parallel with a gap between the two parent girder members 11. Longitudinal openings are provided at both longitudinal ends of the cable rack 10, an upper opening 13 is provided on the upper side, and a lower opening 14 is provided on the lower side.

[0013] The two cable racks 10 of this embodiment have the same structure and are connected in a state where a distance is maintained by a connecting member (not shown). A gap is formed on the side between the two connected cable racks 10.

[0014] The locking tool 20 is a member for connecting the cable rack 10 and the side cover 30. As an example, the locking tool 20 shown in FIG. 4(a) includes a rectangular base portion 21, a fixing portion 22 folded back from one end of the base portion 21, and locking portions 23 folded back from both side ends in the width direction of the base portion 21 to the side opposite to the fixing portion 22. Each locking portion 23 is provided with a locking groove 23a for locking to the parent girder member 11.

[0015] The base portion 21 is provided with a screw hole (hereinafter referred to as "base portion screw hole") 21a formed by burring, and a screw (hereinafter referred to as "fixing screw") 21b can be screwed in so that the locking tool 20 locked to the parent girder member 11 does not come off from the parent girder member 11.

[0016] The fixing portion 22 is provided with a screw hole (hereinafter referred to as "fixing portion screw hole") 22a formed by burring, and a screw (hereinafter referred to as "cover fixing screw") 22b used when fixing the side cover 30 to the fixing portion 22 can be screwed in.

[0017] As shown in FIG. 4(b), two or more fixing portion screw holes 22a can also be provided. Although not shown, similarly, two or more base portion screw holes 21a can also be provided.

[0018] The base part screw hole 21a and the fixing part screw hole 22a can also be formed without burring. In this case, nuts can be welded to the back surfaces of the base part 21 and the fixing part 22, and these nuts can be used as the base part screw hole 21a and the fixing part screw hole 22a.

[0019] In this embodiment, locking tools 20 are provided (locked) on both of the vertically arranged cable racks 10. Specifically, the locking tool 20 locked to the upper rack 10A is locked such that a part of the parent girder member 11 fits into the locking groove 23a, and the fixing part 22 is positioned below the locking part 23.

[0020] Similarly, the locking tool 20 locked to the lower rack 10B is locked such that a part of the parent girder member 11 fits into the locking groove 23a, and the fixing part 22 is provided to be positioned above the locking part 23.

[0021] The side cover 30 is a member that covers the lateral gap generated between a plurality (two in this embodiment) of cable racks 10. As an example, the side cover 30 shown in FIG. 1 is a horizontally rectangular plate material. Existing punching metal (punching plate), flat plate material, etc. can be used for the side cover 30.

[0022] The side cover 30 is sized to cover the gap formed between the vertically arranged (disposed) cable racks 10. The shape and size of the side cover 30 can be appropriately adjusted according to the shape and size (width) of the gap to be covered. When fixing the side cover 30 with fixing screws 21b, it is preferable to provide holes in the side cover 30 with a size such that the shaft part of the fixing screw 21b passes through and the head part does not pass through.

[0023] A plurality of side covers 30 can be attached along the longitudinal direction of the cable rack 10. In this case, adjacent side covers 30 may or may not be connected to each other.

[0024] As shown in Figures 2(a) and 2(b), an upper cover 40 is provided at the upper opening 13 of the topmost cable rack 10 (the uppermost one in this embodiment). The upper cover 40 may be the same as a conventional cover. The upper cover 40 may be provided in the same manner as a conventional cover.

[0025] A lower cover 50 is provided at the lower opening 14 of the lowest cable rack 10 (the lower side in this embodiment). The lower cover 50 can be the same as a conventional cover. The lower cover 50 can be provided in the same manner as a conventional cover.

[0026] The cable rack installation structure configured as above can be expected to provide the following effects, for example. (1) Since the upper covers 40 other than the topmost ones and the lower covers 50 other than the bottommost ones are not required, construction efficiency can be improved and construction costs can be reduced. (2) Maintenance is easier because the inside can be checked simply by removing the side cover 30. (3) It can effectively prevent small animals from entering through gaps on the sides. (4) It can block ultraviolet rays that come through the gaps on the sides, preventing deterioration of the cable. (5) The side covers 30 can be attached after the wiring work is completed, which makes the installation easier than installing the upper cover 40 and the lower cover 50 during the wiring work. (6) When a punched plate is used as the side cover 30, a beautiful appearance can be ensured, and the design is superior to that of the conventional structure. (7) When a punched plate is used as the side cover 30, ventilation can be ensured, and the temperature inside the cable rack 10 can be prevented from rising. (8) When the side cover 30 is of the screw-fastening type, it can be attached and detached with a single tool such as a screwdriver, making installation and replacement work extremely easy. (9) When an existing punched plate or the like is used as the side cover 30, no processing is required in the factory, which improves the production efficiency of the factory. (10) The size of the side cover 30 is not affected by the width of the cable rack 10, so it can be reused in renovation work, etc.

[0027] The configuration of this embodiment is merely an example, and the configuration of the cable rack installation structure of the present invention is not limited to the configuration of this embodiment. The cable rack installation structure of the present invention can be modified by adding, omitting, or replacing components within the scope of the gist of the invention. For example, the following modifications are possible:

[0028] -Variation 1- In the above embodiment, the cable racks 10 are provided in two tiers spaced apart in the vertical direction, but the cable racks 10 can also be provided in three or more tiers spaced apart in the vertical direction. In this case, a side cover 30 can be provided for each gap between the cable racks 10 lined up vertically, or a large-sized side cover 30 that spans multiple gaps can be used to cover the gaps.

[0029] -Variation 2- In the above embodiment, an example is given in which an upper cover 40 separate from the side covers 30 is provided to cover the upper opening 13 of the topmost (upper) cable rack 10, but the upper cover 40 can also be configured as an integral part with either or both of the side covers 30 on either side of the cable rack 10.

[0030] -Variation 3- In the above embodiment, an example is shown in which a bottom cover 50 separate from the side covers 30 is provided to close the lower opening 14 of the lowest (lower) cable rack 10, but the bottom cover 50 can also be configured as an integral part with either or both of the side covers 30 on both sides of the cable rack 10. In this case, the bottom cover 50 is applied to the outside of the cable rack 10.
