Embodiment Construction

[0010] See figure 1 , figure 2 The shown bridge upper construction safety guardrail includes a group of interconnected guardrails and struts 5 supporting the guardrail; the guardrail includes a rectangular frame 1 welded by square steel pipes, a metal mesh 2 installed in the upper part of the rectangular frame and a lower part The metal foot plate 3 is welded with horizontal square steel pipes as reinforcing ribs 7 in the rectangular frame 1. The metal foot plate is used to prevent objects from falling and hurting people. It can be sprayed with red and white paint, which is both beautiful and rust-proof. Adjacent guardrails are connected by bolts 4 passing through the rectangular frame uprights 1a. The struts 5 are made of circular steel pipes and are installed on both sides of the rectangular guardrail. The upper ends of the struts are fixedly connected to the vertical poles of the rectangular frame by bolts, and the lower ends of the struts are inserted into the pre-embed...

Abstract

The invention provides a safety protection railing for construction of an upper portion of a bridge. The safety protection railing comprises a group of guardrails which are mutually connected and supporting rods (5) supporting the guardrails. Each guardrail comprises a rectangular frame (1) formed by welding square steel tubes, a metal net (2) installed on the upper portion of the rectangular frame and a metal paste foot plate (3) installed in the lower portion; adjacent guardrails are connected via bolts (4) penetrating stand rods (1a) of the rectangular frames; the supporting rods (5) are installed on the two side surfaces of each rectangular guardrail; the upper ends of the supporting rods are fixedly connected to the stand rods of the rectangular frames via bolts and the lower ends of the supporting rods are inserted in embedded bars (6) of a bridge protecting wall and are fixed by tightening bolts. The safety protection railing is simple in structure and rapid to install and dismount, is safe and reliable, is firm and durable after being formed, is flexible and convenient to use, and is great in protection performance and reusability.

Description

technical field [0001] The invention belongs to the technical field of building construction safety protection devices, and is mainly used for safety protection fences in highway engineering bridge construction. Background technique [0002] For a long time, the construction of the upper structure of the bridge has always been a high-risk work. Since the bridge anti-collision wall has not yet been constructed, the upper structure of the bridge is full of safety hazards. The existing edge protection is mainly erected by scaffolding, which is complicated to erect and difficult to dismantle. High labor costs, large construction safety hazards, irregularities and other shortcomings. Contents of the invention [0003] The purpose of the present invention is to solve the shortage of border protection facilities in the existing bridge construction, and provide a bridge upper construction safety protection fence which is flexible and convenient to disassemble, has good protection ...
