Prefabricated guardrail

Abstract

A prefabricated guardrail is formed by connecting a plurality of sections of guardrail bodies. The guardrail body is composed of transverse steel bars and section steel bars, and the section steel bars comprise a first embedded steel bar section, a second embedded steel bar section and a frame steel bar section which are connected. A lateral opening is formed in the bottom of the frame steel bar section, the first embedded steel bar section is located in the lateral opening, the bottom of the second embedded steel bar section is connected to the first embedded steel bar section, and the bottom of the second embedded steel bar section is also located in the lateral opening; a junction box and an embedded lamp are embedded in the guardrail body, and a pipeline communicated with the junction box and the embedded lamp is further arranged in the guardrail body. An additional guardrail is arranged at the top of the guardrail body. Compared with the prior art, the anti-collision guardrail is prefabricated in an inverted mode, a horseshoe opening is formed in the upper portion, bubbles are reduced during concrete pouring, meanwhile, the compactness during concrete pouring is improved, the top face of the guardrail adopts a steel formwork as a bottom formwork, the glossiness of concrete on the top face of the guardrail is improved, and the overall appearance quality is improved.

Description

technical field [0001] The invention belongs to the field of guardrails, in particular to a prefabricated guardrail. Background technique [0002] Prefabricated guardrails have a wide range of application values ​​in the field of bridge construction and construction research. The construction accuracy and internal and external quality control of guardrails will directly affect the protective effect and construction efficiency of the anti-collision wall. Therefore, it is necessary to conduct in-depth research on the key technologies of its construction to lay the foundation for popularization and application. [0003] The existing cast-in-place guardrail products have the following disadvantages: first, there are many pouring procedures for on-site construction, the operation lasts for a long time, and there are many external interference factors, so it is difficult to guarantee the processing accuracy and appearance quality; second, there are high noise and high pollution in...

AI Technical Summary

Problems solved by technology

[0003] The existing cast-in-place guardrail products have the following disadvantages: first, there are many pouring procedures for on-site construction, the operation lasts for a long time, and there are many external interference factors, so it is difficult to guarantee the processing accuracy and appearance quality; second, there are high noise and high pollution in the on-site construction 1. High-risk "wet work", more construction waste is generated, and the impact of on-site pouring and pounding construction on surrounding noise and dust is also relatively serious; Boxes, etc. need to wait for the cast-in-place guardrail concrete to meet the strength requirements before construction, prolonging the construction period and increasing the cost

Fourth, on-site construction requires a lot of manpower, and the efficiency is not high, forming an unfavorable situation of "doing twice the result with half the effort"
