Description

Technical Field

[0001] The utility model relates to the field of scaffolding, in particular to a scaffolding fixing structure. Background Art

[0002] Scaffolding is a working platform set up to ensure the smooth progress of each construction process. For prefabricated buildings, triangular truss cantilever scaffolding is generally used. Regardless of whether a steel cantilever frame or a triangular truss cantilever scaffold is used, the upper frame is fixed by welding short-end steel bars on the steel as limiters, and then placing the frame. This construction method requires steel bars to be welded and fixed according to the horizontal distance of the frame, and the welding of steel bars will cause certain damage to the I-beams. After the construction is completed, the steel bars need to be cut, which reduces the turnover times of the I-beams, and the cut steel bars cannot be circulated and reused. It wastes manpower for welding and cutting, and wastes materials, and can only be applied to the erection and fixation of frames with a single horizontal distance.

[0003] In the prior art, the fixing structure of the external scaffolding with application number CN202123168848.X, in the above scheme, is welded to the upper surface of the upper piece fixing piece, and there is no need to weld and fix it with the I-beam, and the I-beam will not be damaged. The bolts are equipped with gaskets and double nuts to enhance the overall stability and reliability. The fixed structure can be processed centrally to avoid on-site hot work, which is conducive to safe and civilized construction management on site. When installing the fixed structure, place the structure in the designated position, rotate the lower piece fixing piece under the I-beam, and the upper piece fixing piece and the lower piece fixing piece clamp the I-beam, and tighten the bolts to fix it. Loosen the bolts, rotate the lower fixing piece to the outside of the I-beam, and it can be disassembled. However, in the above scheme, when the limiter is installed on the I-beam, if the sizes of the I-beams are different, it is inconvenient to install it, and it is difficult to fix the limiter after installation, which is prone to shaking. It is easily constrained by conditions during use, and it is not convenient to install on I-beams of different sizes. How to invent a scaffolding fixing structure to improve these problems has become an urgent problem to be solved by technicians in this field. Utility Model Content
