Construction safety protective fence on lower portion of bridge

Abstract

Provided is a construction safety protective fence on the lower portion of a bridge. The fence comprises a set of connected protective fences and metal baseplates, wherein one end of each metal baseplate is welded to the bottom of the corresponding protective fence, and the metal baseplates are fixedly connected to the surface of the bridge; the protective fences comprise rectangular frames (1) which are welded by square steel tubes, metal meshes (2) which are mounted on the upper portions in the rectangular frames and metal heel staying plates (3) which are on the lower portions of the rectangular frames, channel steels (8) are arranged between adjacent protective fences, and the adjacent protective fences are connected through bolts (4) which penetrate vertical rods (1a) of the rectangular frames and the channel steels; the metal baseplates comprise baseplate frames (5) and metal plates (9), wherein one end of each baseplate frame (5) is welded to the bottom of the corresponding rectangular frame, the metal plates (9) are welded to the baseplate frames, and the inner ends of the metal plates are welded to the metal heel staying plates; the bottom faces of the baseplate frames are inserted into embedded bars of a bridge protective wall and screwed by the bolts, and the adjacent baseplate frames are connected through the bolts. The construction safety protective fence on the lower portion of the bridge is flexible and convenient to disassemble and assemble, good in protective performance, and safe and reliable and can be recycled.

Description

technical field [0001] The invention belongs to the technical field of construction safety protection devices, and is mainly used in the technical field of edge protection related to bridge tie beams, cover beams and the like in highway engineering. Background technique [0002] The construction of tie beams and cover beams of bridges has always been a high-risk work, and there are many safety accidents. However, the general protection of bridges at heights requires the erection of scaffolding and safety nets, which have long erection time, complicated erection, difficulty in dismantling, and high construction costs. The construction of bridge tie beams and cover beams not only does not significantly improve the safety, but also increases the difficulty of work, prolongs the working time of construction personnel at high altitudes, and increases the difficulty of safety management. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to solve the above...

Problems solved by technology

[0002] The construction of tie beams and cover beams of bridges has always been a high-risk work, and there are many safety accidents. In general, scaffolding and safety nets are required for the edge protection of high-altitude bridge operations, which has long-term erection time, complicated erection, difficult dismantling, and high construction costs. Shortcomings such as difficult turnover and other shortcomings make the construction of bridge tie beams and cap beams not only fail to significantly improve safety, but increase the difficulty of work, lengthen the working time of construction personnel at high altitudes, and increase the difficulty of safety management
