Building site guardrail fast to mount and demount

Abstract

A building site guardrail fast to mount and demount comprises a plurality of standing columns parallelly arranged and a plurality of guardrail units. A base plate is welded to the bottom of each standing column and provided with at least three mounting holes, and an expansion bolt for fixing the base plate on the ground penetrates each mounting hole. Each guardrail unit comprises two vertical beams located on two sides of the guardrail unit, a steel plate mesh located between the two vertical beams, and crossbeams which are transversely disposed and used for fixedly connecting the two vertical beams. Each guardrail unit is disposed every two adjacent standing columns, and the vertical beams of the guardrail unit are fixedly connected with the corresponding standing columns in an inserted manner. The building site guardrail has the advantages that the guardrail is simple in structure, uniform in specification and capable of achieve unit type assembling; the specification of each guardrail unit is designed uniformly, circulation in different building sites is achieved, material waste is reduced, and building cost is lowered; the connecting parts are in socket and spigot joint, fast mounting and demounting can be achieved, and time and labor are saved.

Description

technical field [0001] The invention relates to the technical field of safety protection in construction engineering, in particular to a quickly detachable protective railing for a construction site. Background technique [0002] With the rapid development of the construction industry, there are more and more high-rise and super high-rise buildings in cities. In order to ensure the high-quality and efficient completion of the project, higher requirements are put forward for the safety management of the construction process. Temporary safety protection measures on the floor and foundation pit sides of traditional buildings use steel pipes and various fasteners to form protective railings. The whole is connected by fasteners. The disadvantage of this kind of border protection railing is that the overall stability is poor, and it is difficult to meet the construction safety requirements; because the protection railing forms an integral connection, when the partial protection r...

AI Technical Summary

Problems solved by technology

The disadvantage of this kind of border protection railing is that the overall stability is poor, and it is difficult to meet the construction safety requirements; because the protection railing forms an integral connection, when the partial protection railing needs to be changed, it must be disconnected by ventilation and cutting, and the flexibility is poor , which affects the construction progress; the steel pipes are of different lengths and need to be cut, the material loss is large, and it is not easy to carry; the steel pipes and fasteners used are large in quantity and high in cost; the steel pipe poles have open flame operations during the welding process, which emits harmful gases , has a certain impact on the environment

[0003] In order to solve the above problems, the patent document with the publication number CN201786036 discloses a temporary protective railing for building construction, which includes a plurality of columns, and a base plate is welded to the bottom of each column, and the base plate is fixed on the ground by expansion bolts. A guardrail unit is installed between the two columns, and the guardrail unit is fixed to the column by screws. Although the protective railing of this structure avoids open flame operations such as gas cutting and welding when assembling on the construction site, it is necessary to use screws to connect the guardrail unit to the column during installation. The column is fixed, and the installation and disassembly process is time-consuming and laborious, which cannot meet the efficiency requirements of building construction operations
