Adjustable guardrail for municipal construction

Abstract

The invention provides an adjustable guardrail for municipal construction, and relates to the technical field of municipal construction, the adjustable guardrail comprises supporting main frames, the supporting main frames are arranged in an equidistant array mode, and two connecting assemblies are arranged on each supporting main frame; two transverse frames are arranged between the two supporting main frames, and the transverse frames are connected with the supporting main frames through connecting assemblies. The supporting main frame and the rotating hanging piece can rotate more flexibly, and the problems of rigidity and deformation of angle adjustment are avoided; hanging rods at the left end and the right end of a transverse frame are connected with a rotating hanging piece and a fixed rotating piece in a hanging mode respectively, meanwhile, a protection rod is clamped with the transverse frame through an installation clamping groove, the transverse frame, the protection rod and a connecting assembly are assembled conveniently and rapidly, and the problems that in the guardrail rotating adjusting process, a guardrail body is hard, a frame body is prone to deformation, and meanwhile a large number of bolts are needed for connection are solved. The problems that in the prior art, the assembly process is troublesome, time and labor are wasted in batch assembly, and most warning boards are fixed to guardrails in a welded mode and are difficult to disassemble are solved.

Description

technical field [0001] The invention relates to the technical field of municipal construction, in particular to an adjustable guardrail for municipal construction. Background technique [0002] Municipal engineering refers to the construction of municipal facilities. Various public infrastructure constructions supporting urban life belong to the category of municipal engineering, such as common urban roads, bridges, subways, and various pipelines closely related to life. Guardrail is one of the devices used in municipal construction to protect the construction area. [0003] However, as far as the current traditional adjustable guardrail is concerned, the rotation adjustment process is relatively rigid, the frame body is prone to deformation, and at the same time, a large number of bolts are required for connection as a whole, and the assembly process is cumbersome, resulting in time-consuming and labor-intensive assembly in batches, and the warning boards are mostly welded ...

AI Technical Summary

Problems solved by technology

[0003] However, as far as the current traditional adjustable guardrail is concerned, its rotation and adjustment process is relatively rigid, and the frame body is prone to deformation. At the same time, a large number of bolts are required for connection as a whole, and the assembly process is troublesome, resulting in time-consuming and laborious batch assembly. It is fixed on the guardrail by the way, it is difficult to remove it, so the content of the warning board cannot be replaced
