Description

Technical Field

[0001] This utility model belongs to the field of building component technology, and in particular relates to a wall-mounted cable tray edge fixing structure. Background Technology

[0002] In stairwells or electrical shafts of high-rise buildings, fireproof vertical cable trays are used in some areas to prevent the spread of fire along the vertical passage during a fire, ensure the continuous operation of emergency power and communication systems, and buy time for personnel evacuation and rescue.

[0003] Traditional cable trays bear stress on the crossarms, but for vertically mounted wall-mounted cable trays, stress is mainly on the tray itself and the support. To address this, a wall-mounted cable tray edge-fixing structure was designed. This structure uses tensile force to reinforce the connection between the cable tray and the supporting wall, thus keeping the cable tray fixed and preventing accidental deformation. Utility Model Content

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A wall-mounted cable tray edge fixing structure, which includes a cable trench opened in a supporting wall; a bracket is fixedly connected to the front side of the supporting wall by bolts; a cable tray is provided in front of the supporting wall; edging strips are fixedly connected to the left and right sides of the cable tray by bolts; a pull plate is fixedly connected to the inner cavity of the edging strip by bolts; two threaded posts are welded to the surface of the pull plate; a positioning plate is fixedly connected to the front side of the supporting wall by bolts; the surface of the threaded post is slidably connected to the inner cavity of the positioning plate; and a nut is threadedly connected to the surface of the threaded post.

[0006] Preferably, the cable tray is fixedly connected to the surface of the bracket by bolts, and the threaded post is fixedly connected to the positioning plate by a nut.

[0007] Preferably, a slotted gasket is placed between the pull plate and the positioning plate, and the surface of the threaded column is slidably connected to the inner cavity of the slotted gasket.

[0008] Preferably, a washer is slidably connected to the surface of the threaded post, and the washer is located between the surface of the nut and the positioning plate.

[0009] Preferably, the inner cavity of the edge banding strip is fixedly connected to a reinforcing plate by bolts, and the reinforcing plate is fixedly connected to the bracket by bolts.

[0010] Preferably, both the upper and lower sides of the edge banding strip are fixedly connected to edge banding plates by bolts, and both edge banding plates are fixedly connected to the cable tray by bolts.

[0011] The beneficial effects of this utility model are: 1. This utility model uses bolts to fix the pull plate and the edge strip together, then places the positioning plate on the surface of the pull plate and fixes the positioning plate to the surface of the supporting wall. Then, bolts are used to fix the positioning plate, thereby strengthening the cable tray with tensile force. This achieves the purpose of keeping the main body of the cable tray fixed and preventing accidental deformation of the cable tray. 2. By setting the edge banding plate, the upper and lower sides of the edge banding strip can be pressed and fixed to the cable tray, which can prevent the edge banding strip from "curling up".

[0014] In the following description, embodiments of the wall-mounted cable tray edge fixing structure of the present invention will be described with reference to the accompanying drawings.

[0015] Example 1: Figure 1-5This invention illustrates a wall-mounted cable tray edge-fixing structure according to an embodiment of the present invention. It includes a cable trench 2 formed in a supporting wall 1; a bracket 3 is bolted to the front of the supporting wall 1; a cable tray 4 is positioned in front of the supporting wall 1; edging strips 5 are bolted to both sides of the cable tray 4; a pull plate 6 is bolted to the inner cavity of the edging strip 5; two threaded posts 7 are welded to the surface of the pull plate 6; a positioning plate 8 is bolted to the front of the supporting wall 1; the surface of the threaded posts 7 is slidably connected to the inner cavity of the positioning plate 8; a nut 9 is threadedly connected to the surface of the threaded posts 7; the cable tray 4 is bolted to the surface of the bracket 3; the threaded posts 7 are fixedly connected to the positioning plate 8 via the nut 9; a slotted washer 10 is placed between the pull plate 6 and the positioning plate 8; the surface of the threaded posts 7 is slidably connected to the inner cavity of the slotted washer 10; a washer ring 11 is slidably connected to the surface of the threaded posts 7; and the washer ring 11 is located between the nut 9 and the surface of the positioning plate 8.

[0016] Example 2: Figure 1-5 This invention illustrates a wall-mounted cable tray mounting structure according to an embodiment of the present invention. It includes a cable trench 2 formed in a supporting wall 1; a bracket 3 is bolted to the front side of the supporting wall 1; a cable tray 4 is positioned in front of the supporting wall 1; edging strips 5 are bolted to both sides of the cable tray 4; a pull plate 6 is bolted to the inner cavity of the edging strip 5; two threaded posts 7 are welded to the surface of the pull plate 6; a positioning plate 8 is bolted to the front side of the supporting wall 1; and the surfaces of the threaded posts 7 slide... The inner cavity of the positioning plate 8 is connected to the threaded column 7, which is threaded with a nut 9. The inner cavity of the edge banding strip 5 is fixedly connected to the reinforcing plate 12 by bolts. The reinforcing plate 12 is fixedly connected to the bracket 3 by bolts. The upper and lower sides of the edge banding strip 5 are fixedly connected to the edge banding plate 13 by bolts. Both edge banding plates 13 are fixedly connected to the cable tray 4 by bolts. By setting the edge banding plate 13, the upper and lower sides of the edge banding strip 5 can be pressed and fixed to the cable tray 4, which can prevent the edge banding strip 5 from "curling up".

[0017] Working principle: When using this utility model, the user fixes the edge strip 5 to the left and right sides of the cable tray 4, then slides the pull plate 6 into the inner cavity of the edge strip 5, and uses bolts to fix the pull plate 6 and the edge strip 5. Then, the positioning plate 8 is placed on the surface of the pull plate 6, and the threaded post 7 slides in the inner cavity of the positioning plate 8. Then, the positioning plate 8 is pulled until it contacts the surface of the supporting wall 1. The positioning plate 8 is then fixed in position with bolts, and the threaded post 7 and the positioning plate 8 are fixed together with nuts 9. This fixes the pull plate 6 and the positioning plate 8, thereby strengthening the cable tray 4 with tension, keeping the main body of the cable tray 4 fixed, and preventing accidental deformation of the cable tray 4.

[0018] In summary, this wall-mounted cable tray edge-fixing structure uses bolts to fix the pull plate 6 and the edge strip 5 together. Then, the positioning plate 8 is placed on the surface of the pull plate 6 and fixed to the surface of the supporting wall 1. Finally, the positioning plate 8 is fixed with bolts, thereby strengthening the cable tray 4 with tensile force. This achieves the purpose of keeping the cable tray 4 fixed and preventing accidental deformation of the cable tray 4.
