Description

Technical Field

[0001] The utility model belongs to the technical field of building formwork clamps and relates to a universal clamp for fixing the edges of multi-directional building formwork. Background Art

[0002] A building formwork is a temporary support structure, which is made according to the design requirements to form concrete structures and components into the specified positions and geometric dimensions, keep their correct positions, and bear the self-weight of the building formwork and the external loads acting thereon. The purpose of carrying out formwork engineering is to ensure the quality of concrete projects, construction safety, speed up the construction progress and reduce the project cost. With the development of engineering technology, various new materials have been gradually applied to the field of building formwork. The emergence of various new formworks has triggered a large number of studies on them by domestic and foreign scholars, but there are the following problems in the fixation of the existing formwork edges during the experiment.
