AI Technical Summary
The existing prefabricated steel-wood composite wall connection method, when applied to square steel pipes and walls, is prone to corner bracket design, which increases the gap between the metal plate and the wall, and undermines the overall structural stability and lateral stiffness of the steel-wood composite wall after connection.
Thermal insulation components are connected to the steel-wood composite wall using self-tapping screws to form the first and second shear-resistant components. A combination of vertical and horizontal steel plates is used, connected by self-tapping screws and fastening bolts to form an integral structure, increasing the stability and lateral stiffness of the connection.
The mechanical properties of the wall connections have been optimized, improving the overall structural stability and lateral stiffness of the steel-wood composite wall, while also enhancing the adjustability and waterproofing of the connections.
