Description

Technical Field

[0001] The utility model relates to the technical field of building templates, in particular to an auxiliary connection device for building templates. Background Art

[0002] Building formwork is a temporary support structure used to shape concrete structures and components into specified positions and geometric dimensions and maintain their correct positions, while bearing the weight of the building formwork and external loads acting on it. Its main function is to provide support to ensure the stability of the structure during construction; to shape and form so that the concrete structure can obtain a pre-designed geometric shape during construction, and a connection device is required when assembling the building formwork.

[0003] Common auxiliary connection devices for building formwork generally consist of bolts and nuts. When in use, two building formworks are first assembled and then connected and fixed by multiple sets of bolts and nuts. However, in order to improve the connection firmness between the two formworks, this method requires fixing the left and right and top and bottom positions, so that at least two sets of bolt and nut assemblies are required between the two building formworks. In addition, due to the limitation of the bolt stroke, when screwing a single bolt, it is necessary to completely screw it into the thread groove. This makes the connection process in large or complex formwork systems time-consuming and labor-intensive, and cannot meet the working requirements of the building formwork. For this reason, an auxiliary connection device for building formwork is proposed. Utility Model Content
