AI Technical Summary

Technical Problem

The pedestrian walkways of railway T-beam bridges are prone to overturning in extreme weather conditions, and there are also problems such as concrete spalling, cracks and exposed steel bars, which affect the safety of train operation and maintenance personnel.

Method used

The reinforced structure uses a combination of A-type, B-type, and C-type locking buckles, and is fixed to the railing with U-shaped connectors and anti-fall steel bars to form a composite snap-fit ​​structure, ensuring a rigid connection between the walkway and the angle steel bracket and preventing overturning and falling.

Benefits of technology

Without damaging the existing bridge structure, this effectively prevents the pedestrian walkway from being overturned in extreme weather conditions such as tornadoes, reduces the risk of falling, and improves the safety of railway operations and the convenience of construction.

Abstract

The utility model relates to the technical fields of bridge construction especially relates to a railway T beam bridge angle steel support walking board wind -resisting reinforcing structure, include: standard section reinforcing subassembly, be located between adjacent standard section walking board, including the A type lock catch and B type lock catch of overlapping arrangement, A type lock catch and B type lock catch top are fixed through U type connecting piece, and the opening of bottom is connected to angle steel support. Beam end reinforcing subassembly, be located in beam end walking board end, including C type lock catch and spacing steel sheet, C type lock catch and spacing steel sheet top are fixedly connected through bolt or rivet, and the opening of C type lock catch bottom is connected to angle steel support, and spacing steel sheet is fixed to beam end side wall. Anti -falling reinforcing bar, pass through C type lock catch, and upwards extend and hook up the handrail. The present application utilizes the characteristics that the existing walking board arrangement gap and its lap joint angle steel support, has realized the effective reinforcing of standard section walking board and beam end walking board, can also play the function of preventing beam end walking board from falling.
