Description

Technical Field

[0001] The utility model relates to a building template locking device, belonging to the field of building templates. Background Art

[0002] Building formwork is a temporary supporting structure, manufactured according to design requirements, which allows concrete structures and components to be formed according to specified positions and geometric dimensions, maintain their correct positions, and bear the deadweight of the building formwork and external loads acting on it. For building components with rectangular cross-sections, the building templates also need to be supported in a corresponding shape, that is, four building templates form a structure with a rectangular cross-section. After the four building templates form a rectangular structure, they need to be aligned and locked. At present, the locking structure is generally a stud with a clamping portion, and a sleeve with an L-shaped clamping plate is sleeved on the stud. When the nut on the stud is screwed with an electric tool, the clamping portion is clamped on a side of the building template, and then the L-shaped clamping plate is clamped at the right-angled corner formed by two adjacent building templates. Under the extrusion of the nut, the L-shaped clamping plate and the clamping portion jointly press the building template to achieve the purpose of locking the building template. However, when the nut is screwed with an electric tool, the clamping portion will rotate due to the small contact range between the clamping portion and the building template. The probability of the clamping portion detaching from the side of the building template is relatively high, and repeated operations are required by personnel, which not only affects the construction efficiency, but also requires high operating proficiency. Therefore, it is necessary to design a building template locking device that prevents the clamping portion from detaching from the side of the building template. Utility Model Content
