Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a sawtooth interlocking aluminum-wood fastener. Background Technology

[0002] With the increasing complexity of underground building structures and the higher requirements for construction quality and aluminum formwork turnover rate, the combined use of aluminum and wood formwork systems has emerged. To achieve an effective combination of aluminum and wood formwork, issues such as connection and fixing, and construction difficulty need to be addressed.

[0003] Traditional methods for connecting aluminum and wooden formwork include direct bolt fixing and C-slot fixing. However, existing technologies have the following drawbacks:

[0004] (1) The aluminum formwork and the wooden formwork are fixed together with bolts. This requires drilling holes in the wooden formwork, which weakens the strength of the material and affects its load-bearing capacity. The bolt holes need to be precisely aligned when bolting, which increases the complexity and workload of manufacturing and installation.

[0005] (2) The aluminum formwork and the wooden formwork are fixed by C-groove. The C-groove needs to be processed to the required length, which results in low applicability and reusability, and high construction cost. At the same time, the material dimensions of the wooden formwork system are strictly required. If there is a slight deviation, the fit cannot be tight, which makes the construction more difficult.
