Connecting structure of fabricated steel bridge deck concrete crash barrier and complete set of construction method of connecting structure

Abstract

The invention discloses a connecting structure of a fabricated steel bridge deck concrete crash barrier and a complete set of construction method of the connecting structure. The connecting structurecomprises a prefabricated concrete guardrail, the prefabricated concrete guardrail comprises embedded inverted-T-shaped perforated steel plate connecting pieces, embedded angle steel, embedded high-strength bolts, guardrail anti-collision steel bars and a guardrail body, the guardrail anti-collision steel bars, the embedded inverted-T-shaped perforated steel plate connecting pieces and the embedded angle steel are connected in a welded mode, and the concrete guardrail is prefabricated after the high-strength bolts are embedded. The precast concrete guardrail is reliably connected with the steel bridge deck through the high-strength bolts. The problems that in current steel bridge deck guardrail construction, welding residual stress is large, and construction procedures are complex are solved; and technical support is provided for assembly construction of the steel bridge deck concrete guardrail through the provided complete construction technology.

Description

technical field [0001] The invention belongs to the field of bridges, and in particular relates to a connection structure of an assembled steel bridge deck concrete anti-collision guardrail and a complete set of construction technology thereof. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily to be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Due to its light weight, large bearing capacity, high degree of assembly, and rapid construction, steel bridges have been widely used in highways and urban bridges. Generally speaking, steel bridge deck crash barriers can be divided into rigid barriers (such as concrete barriers) and semi-rigid barriers (such as steel structure barriers). Concrete guardrails occupy a conside...

AI Technical Summary

Problems solved by technology

But the inventor found that: this method carries out a large amount of welding on the steel bridge deck, so that the steel bridge produces relatively large welding residual stress and residual deformation, which affects the service life of the steel bridge, and the process is more complicated, delaying the construction progress
