[0002] With the widespread adoption of aluminum alloy formwork in residential projects, its advantages, such as high precision, fast construction cycles, high concrete quality, high reuse rates, and low waste generation, have become increasingly prominent compared to traditional wooden formwork, which suffers from low strength, long construction cycles, low turnover rates, and high construction waste generation. Therefore, in non-standard residential floors using aluminum alloy formwork systems, a combination of aluminum alloy and wooden formwork is being adopted to improve the quality of concrete construction in these floors, in order to avoid the drawbacks of all-wood formwork construction.

[0003] In traditional wood formwork systems, the middle layer boards and wooden beams are connected with iron nails, while in aluminum formwork systems, the aluminum panels are connected with pins. In this project, two different formwork systems, aluminum and wood, are used on the same construction floor. The connection at the junction of the aluminum and wood formwork is a difficult problem. Because the two systems are made of different materials, they cannot be directly connected using conventional methods. To this end, this article proposes a connection device for aluminum alloy formwork and wood formwork. Utility Model Content
