Description

Technical Field

[0001] The utility model relates to the technical field of cantilever I-beam fixing, in particular to a clamping and fixing mechanism for cantilever I-beams. Background Art

[0002] In construction projects, cantilever rope scaffolding is a common construction equipment. Its safety and stability are crucial to the smooth progress of the entire project. Among them, I-beams are the main components of cantilever rope scaffolding, and their quality directly affects the safety of the scaffolding. The I-beam should have a cantilever end on the outside and an anchor end on the inside. The proportional relationship between the cantilever end and the anchor end is based on this U-shaped reinforcement, which is used as the dividing line. This is because the cantilever end of the I-beam needs to withstand greater tension, while the anchor end needs to have sufficient stability. Therefore, a reasonable proportional relationship can ensure that the I-beam will not deform or break when subjected to tension. The clamping and fixing mechanism of the cantilever I-beam is a device for anchoring the I-beam, which assists in fixing the position of the I-beam;

[0003] The clamping and fixing mechanism of the cantilever I-beam is mostly U-shaped in design and embedded in the concrete for fixation, with the open end facing downward. After the I-beam is inserted inside, multiple sets of wooden boards are inserted in the gap as fillers to achieve the anchoring operation of the I-beam. This method inserts wooden boards inside the U-shaped steel bar to compress and fix the I-beam. The process of adjusting the wooden boards is cumbersome, the safety is poor, and it is inconvenient to use. Therefore, it needs to be improved to make it easier to use. Utility Model Content
