Fixing device and construction method for embedded parts of anti-collision guardrail

Abstract

The invention relates to the technical field of building construction, in particular to a fixing device and a construction method for embedded parts of anti-collision guardrails. The middle part of the positioning steel plate has positioning holes corresponding to the embedded screws one by one, and the two sides of the positioning steel plate have positioning holes corresponding to the embedded screws. The mounting holes corresponding to the positioning bolts allow the embedded parts to be pre-fixed on the positioning steel plate through nuts, and the positioning bolts and nuts are used to fix the positioning steel plate on the top transverse rib of the formwork of the anti-collision wall to fix the embedded parts on the installation Position, so that the formwork can be used as the support system to avoid the displacement of the embedded parts during the concrete vibration, which will affect the subsequent installation of the guardrail, thereby improving the installation and construction quality of the embedded parts of the anti-collision guardrail; Fine-tune the elevation and plane position of the parts, so that the embedded parts can be positioned accurately, thereby improving the installation accuracy of the embedded parts of the anti-collision guardrail, and providing quality assurance for the subsequent installation of the guardrail.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a fixing device and a construction method for embedded parts of anti-collision guardrails. Background technique [0002] With the continuous growth of my country's national economy and the development of urban infrastructure construction, cities and highway bridges, underpass tunnels, viaducts and other projects are undergoing large-scale construction. If the guardrail project is not installed smoothly, it will affect the appearance quality of the anti-collision guardrail and directly affect the appearance of the city. Before the installation of the guardrail, it is necessary to reserve the embedded parts of the guardrail in advance on the top of the anti-collision wall. The installation quality of the embedded parts directly affects the quality of the subsequent guardrail installation. Therefore, higher requirements are put forward for the installation of the embed...

Problems solved by technology

In the subsequent concrete pouring and vibrating process, if the spot welding method is used, the steel bars will be displaced, and the embedded parts will be displaced simultaneously; if the binding installation is used, the horizontal and vertical displacements of the embedded parts will be different to varying degrees due to the weak binding. Displacement, which leads to the installation quality of the embedded parts cannot meet the construction requirements, causing great hidden dangers to the subsequent guardrail installation, which is not expected by those skilled in the art
