Description

Technical Field

[0001] The present invention relates to the technical field of protective frames, and in particular to a novel protective outer frame and a construction method thereof. Background Art

[0002] The protective frame is a temporary protective device set up independently of the scaffolding in construction projects. It uses steel pipe components to construct an isolation barrier. Current buildings mainly use steel pipe floor-standing scaffolding, which has cumbersome installation steps and many technical control points.

[0003] Small accessories such as fasteners and screws on existing steel pipe protective frames are frequently disassembled and assembled and are easy to lose, with high maintenance costs. Eccentric connections (such as fasteners) are used, relying on sliding friction to transfer loads. The actual bearing capacity is lower than the theoretical value, and there is a risk of sliding. Improper control of the fastener tightening torque (over-tightening or under-tightening) can easily lead to steel pipe collapse or connector slippage, causing structural instability. Insufficient control of parameters such as the verticality and length of steel pipes (such as bending and uneven length of steel pipes) can easily lead to construction errors and cause structural deformation. Manual operation errors affect the stability of the frame, and the ground must be flat and the bearing capacity must meet the standards. Complex terrain or soft soil foundations require additional reinforcement, and the adaptability is poor. Therefore, we propose a new type of protective external frame and its construction method. Summary of the Invention
