Description

Technical Field

[0001] The utility model relates to the technical field of building construction equipment, in particular to a bottom diagonal brace fixing device. Background Art

[0002] As my country's urbanization process continues to deepen, the scale and number of buildings are rapidly increasing. Hospitals, schools and other buildings with tight construction periods need to consider interleaving construction procedures in advance. During the construction of large-scale building structures, ground-mounted steel pipe scaffolding cannot meet the requirements of rapid construction, and cantilever scaffolding projects have developed rapidly.

[0003] The frame of the basket-type cantilever scaffolding is erected on the cantilever structure, which is composed of I-beams connected with pre-embedded high-strength bolts and inclined rods with basket screws. Compared with traditional methods, the basket-type cantilever scaffolding not only saves the use of materials such as I-beams, but also greatly saves the cost of subsequent cutting of embedded parts and repair costs for risks such as water seepage.

[0004] The flower basket cantilever scaffolding commonly used at present is mainly composed of cantilever I-beams and upper diagonal tie rods. However, the upper diagonal tie rods need to wait until the concrete reaches a certain strength before they can be tied, which has a great impact on the construction period. If the upper diagonal tie rods are not tied and the scaffolding is directly erected on the cantilever I-beams, the bending moment of the I-beams is too large, which poses a great safety risk.
