Modular spliced protective guard

Abstract

The invention discloses a modular spliced protective guard which comprises a first protective guard body and a second protective guard body, wherein a side edge clamping cavity allowing a side edge clamping block to be inserted in a butt joint mode is inwards formed in each of the top end and the bottom end of the left side part of the second protective guard body, a push block rod is horizontallyfixed to the center of the inner side wall surface of the groove cavity of each side edge clamping cavity, an arc surface clamping groove allowing an arc face clamping head to be clamped in in a matched mode is inwards formed in each of the top wall surface and the bottom wall surface of the right end of the groove cavity of each side edge clamping cavity, arc surface clamping heads located on middle clamping block structures are also limited in containing cavities correspondingly formed in the middle clamping blocks in a matched mode, extrusion springs are correspondingly arranged in the containing cavities, the top ends of the extrusion springs are also upwards fixed to the arc surface clamping heads, and the bottom end of the extrusion springs are downwards fixed to the bottom wall surfaces of the containing cavities. By adopting the modular design, the modular spliced protective guard is high in splicing efficiency and high in firmness, greatly improves the working efficiency of bare-handed construction by workers, and has good application and popularization value.

Description

technical field [0001] The invention relates to the related technical field of guardrails, in particular to a modular spliced ​​guardrail. Background technique [0002] In building construction, in order to avoid safety accidents, it is necessary to set up protective fences at dangerous places. The protective fences are suitable for the safety protection of various construction sites and play the functions of separation, blocking and warning. [0003] Because the guardrails in the prior art do not adopt modular design, workers often need to build them with bare hands and use fixed bolts to splice and install them. This traditional construction method not only has low splicing efficiency but also low firmness, which seriously affects work efficiency and labor costs. High strength, poor application value. [0004] Aiming at these deficiencies, the present invention proposes a modular spliced ​​guardrail to solve the above problems. Contents of the invention [0005] The pu...
