Description

technical field [0001] The invention belongs to the technical field of building fasteners, and in particular relates to a square-through fastener reinforced by a building formwork. Background technique [0002] As my country advocates environmental protection and energy-saving production, construction aluminum alloy formwork has been widely used in my country in recent years. The current construction aluminum formwork system is not perfect. For example, there are still functional defects in various accessories of aluminum formwork, which makes it inconvenient and safe for on-site workers to operate and use. Hidden dangers, improper use will cause time delays, delays in work, etc. The current aluminum formwork reinforcement system uses a square buckle mainly composed of a main board, a wedge, a pin, and a connecting nail. For example, the application number: 201610281936.5 discloses a square buckle, including: a main board; There is a pin plate extending upwards from the uppe...
