Construction method of concrete railing column in the middle of bridge road

Abstract

The invention discloses a construction method for a concrete railing column in the middle of a bridge road, which comprises the following steps: 1) pre-casting and fixing several steel bars on the column installation position on the upper surface of the bridge during bridge road construction; 2) prefabricating in a factory Good panel components and baffles. The panel components include two panels fixedly arranged at relative intervals along the front and rear directions; 3) When the column is constructed on site, the pre-cast steel bars are placed between the two panels, and the baffles on the left and right sides of the column The end of the slab is sandwiched between two panels and a pouring space is enclosed between the two panels; 4) Concrete is poured in the pouring space, and the concrete core is formed after the concrete is solidified, and the two panels are separated by the concrete core. The panel and the ends of the baffles on the left and right sides are fixed as a whole. The invention has the advantages of being convenient for prefabrication and transportation, improving the convenience of on-site construction, improving the construction quality and the strength of the installed railings, and the like.

Description

technical field [0001] The invention relates to the technical field of bridge railings, in particular to a construction method for concrete railing columns in the middle of bridge roads. Background technique [0002] Usually, during bridge construction, sidewalks will be set on both sides of the bridge, and bridge railings will be set on the outer edges of the sidewalks to protect pedestrians from falling under the bridge. There are usually wooden structure railings, metal structure railings and concrete structure railings for bridge railings. Among them, concrete structure railings are widely used because of their firm structure, convenient construction, and low cost. The railing of the concrete structure is composed of a plurality of railing columns arranged at intervals, and a railing plate connected between the railing columns, wherein the railing column is a basic component for support. [0003] The existing bridge road concrete railing column structure usually includ...

AI Technical Summary

Problems solved by technology

[0004] This structure and construction method has the following defects: 1. The concrete railing column is a solid structure with a large weight, which is not convenient for prefabrication and transportation, and it is also inconvenient for on-site construction and installation

2 After the railings are installed, the structural properties between the railing columns and the bridge, and between the columns and the barriers are poor, the installation stability and the structural strength of the railings are low, and the safety hazards are relatively large
