Suspension bridge cable groove assembly for building and cable laying method thereof

Abstract

The invention discloses a suspension type bridge cable tray assembly for buildings and a cable laying method. The suspension type bridge cable tray assembly comprises a cable tray and a suspension assembly, the suspension assembly is fixed onto the bottom of a building floor and used for mounting of the cable tray, and the cable tray comprises an I-shaped tray body, two side cover plates and a plurality of binding clamps. The two side cover plates used for opening and closing are in one-to-one correspondence to openings of two sides of the I-shaped tray body, and the binding clamps are longitudinally inserted into two side cavities of the I-shaped tray body. By the cable tray with side openings, during cable laying, cables can be clamped into the binding clamps after being orderly placed on the ground or building floor, then the binding clamps are integrally laterally inserted into the cable tray through two sides of the cable tray, and finally the side cover plates of the cable tray are closed to finish cable mounting. Compared with a conventional cable mounting method, the method is more convenient and higher in operation efficiency.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a suspension bridge cable groove assembly for construction and a cable laying method thereof. Background technique [0002] When the building power and weak current cables are installed, they are drawn out from the general control room (opening and closing station), and then lead to each room by hanging on the bridge cable groove on the bottom of the building floor. The bridge frame for suspending the cable trough is now mostly welded with angle steel door-shaped brackets, anchored on the bottom of the floor, and the cable trough is placed in the door frame, or two suspension rods are used to anchor on the bottom of the floor. into the beam and connected with tie rod bolts. Place the cable trough above the beam. Corresponding to the above-mentioned bridge, the cable trough is a cover-type trough-shaped wire trough. The above-mentioned bridge and cable trough installatio...

AI Technical Summary

Problems solved by technology

The above-mentioned bridge and cable trough installation and cable laying have the following problems: First, no matter the angle steel bridge or the suspension rod beam bridge, the wire troughs are placed on the bridge transverse angle steel or beam, and the total height of the bridge and cable trough is high, occupying The headroom height of some houses; the second is the angle steel bridge or the second suspension bridge, which requires a certain amount of steel; the third is that the elevation of the bottom surface of the beam of the bridge is inconvenient to control, and it is impossible to ensure that each bridge beam is on the same elevation plane; the fourth is that the cable trough needs to be worn It is inconvenient to install into the beam of the bridge frame; fifth, the cable groove is an upper opening wire groove, and the two sides of the wire groove are vertical rods of the bridge frame. When placing the cables, they must be inserted into each bridge frame from one end of the cable groove The cable can only be placed in the wire slot, which is inconvenient to place the cable
