Regional anti-seismic cable bridge

Abstract

The invention discloses a regional anti-seismic cable bridge comprising a bridge body. The cross section of the bridge body is U-shaped. The left side surface of the bridge body is fixedly connected with inserting blocks. The positions, which are corresponding to the inserting blocks, of the right side surface of the bridge body are provided with inserting grooves. The inserting blocks are provided with first screw holes. The internal wall close to the external side surface of the bridge body in the inserting grooves is provided with second screw holes. According to the regional anti-seismic cable bridge, the left side surface of the bridge body is fixedly connected with the inserting blocks, the positions, which are corresponding to the inserting blocks, of the right side surface of the bridge body are provided with the inserting grooves, the inserting blocks are provided with the first screw holes, internal wall close to the external side surface of the bridge body in the inserting grooves is provided with the second screw holes, the two adjacent bridge bodies can be connected in an inserting way through the inserting grooves and the inserting blocks, and then the bolts are utilized to be screwed into the first screw holes and the second screw holes to fix the adjacent bridge bodies so that the structural strength can be effectively enhanced in comparison with the conventional connecting structure of using the connecting rods and the bolts and thus the anti-seismic capacity is higher.

Description

technical field [0001] The invention relates to the technical field of cable bridges, in particular to an anti-seismic cable bridge in different areas. Background technique [0002] Cable trays are divided into trough type, tray type, ladder frame type and grid type and other structures, and are composed of brackets, supporting arms and installation accessories. The bridge frame in the building can be erected independently or attached to various buildings (structures) and pipe gallery supports. It should reflect the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. All parts need to be galvanized. , installed in the open-air bridge outside the building. [0003] The installation method of cable tray is usually to install U-shaped installation accessories on the ceiling, and then lap the cable tray in the installation accessories. Structural strength, while the shock absorption structure in the existing cable tray ...

AI Technical Summary

Problems solved by technology

[0003] The installation method of cable tray is usually to install U-shaped installation accessories on the ceiling, and then lap the cable tray in the installation accessories. Structural strength, while the shock absorption structure in the existing cable tray connection structure is relatively simple, the shock absorption effect is poor, and it cannot be used for shock absorption in different areas of the bridge frame, and there is an urgent need for a cable tray with regional earthquake resistance
