Description

Technical Field

[0001] The utility model relates to a building construction guardrail, in particular to a guardrail used for building construction, and belongs to the technical field of building construction guardrails. Background Art

[0002] Construction refers to the production activities during the implementation stage of engineering construction, and is the process of constructing various types of buildings. During the construction process, in order to prevent pedestrians or vehicles on the road from accidentally entering the construction site, it is generally necessary to set up safety fences to protect the construction site, thereby ensuring the normal progress of construction.

[0003] As shown in the announcement number: CN218205860U, a safety guardrail for construction construction includes a guardrail main body, both ends of the guardrail main body are fixedly installed with columns, the first mounting plate and the second mounting plate are fixedly connected to the columns, an auxiliary support assembly is provided between the first mounting plate and the second mounting plate, and the bottom of the auxiliary support assembly is rotatably connected to the base plate. The utility model has a design of connecting the support rod by rotating one side of the fixed plate. When installing and placing the guardrail main body, the rotating plate is rotated, and the rotating plate drives the first connecting rod to rotate. The rotation of the first connecting rod can drive the two groups of second connecting rods to rotate through the cooperation between the two sets of synchronous wheels and the synchronous belts. When the two groups of second connecting rods rotate, they drive the two groups of screw rods to rotate. The rotation of the screw rods drives the fixed plate to move up and down through the threaded holes, and the support rods drive the base plate to move, thereby achieving the advantage of increasing the stability of the guardrail main body and avoiding tilting and collapse caused by external collisions.

[0004] Common construction guardrails can protect the construction site when in use, but the construction site is generally dusty and is usually shielded by dust nets. However, the existing technology generally installs the dust nets between the support frames by bolts, which is inconvenient, time-consuming and labor-intensive to install or remove. Moreover, in rainy weather, mud will flow from under the guardrail into the construction site, making the foundation pit muddy and affecting the construction progress.

[0005] In view of this, the present utility model is proposed. Utility Model Content
