A kind of anti-collision guardrail matching installation construction device and construction technology

Abstract

The invention provides a construction device and a construction process for matching and installing an anti-collision guardrail. The upper end of the beam and the side beam are provided with a U-shaped fixing plate, the vertical part of the U-shaped fixing plate facing the steel formwork is equidistantly connected to a plurality of T-shaped installation plates, and the T-shaped installation plate is rotatably connected to two support members, The upper and lower ends of the U-shaped fixing plate are equidistantly provided with a number of first through grooves arranged in the front and rear, and the upper ends of the middle beam and the side beam are equidistantly connected to a number of reserved screws arranged in the front and rear, and the upper ends of the reserved screws pass through Compared with the prior art, the present invention has the following beneficial effects: through the first through grooves, the front and rear fastening positions of the U-shaped fixing plate can be adjusted , to improve the use effect.

Description

technical field [0001] The invention relates to a construction device and a construction technique for matching and installing an anti-collision guardrail, and belongs to the technical field of installation and construction of an anti-collision guardrail. Background technique [0002] The prefabricated construction consists of the conventional prefabrication of beams and slabs of the upper structure and the prefabrication of continuous beam segments, and gradually expanded to the prefabrication of piers and columns of the lower structure, slope protection, and prefabrication of small components of gutter cover plates. The concrete anti-collision guardrail (wall) is an important part of the bridge deck and the key safety protection infrastructure in the entire highway bridge project. During the matching and installation of the anti-collision guardrail, the cast-in-place anti-collision guardrail is set on the edge of the side beam. , and use the anti-collision guardrail matchi...

AI Technical Summary

Problems solved by technology

The concrete anti-collision barrier (wall) is an important part of the bridge deck and the key safety protection infrastructure in the entire highway bridge project. During the installation and construction process of the anti-collision barrier, the cast-in-place anti-collision barrier is set on the edge of the side beam , and use the anti-collision guardrail matching installation construction device for pouring construction. At present, the anti-collision barrier matching installation construction device uses formwork for pouring, and the deformation of the anti-collision formwork is often supported by multiple supports. The reserved parts are fastened, but when there is a design error in the reserved parts, the support cannot be installed, which will increase the probability of deformation of the formwork and affect the use effect
