Description

Technical Field

[0001] The utility model relates to the technical field of building construction template reinforcement, in particular to an anti-expansion template reinforcement device. Background Art

[0002] At present, during the construction process, the formwork at the external corners is prone to expansion when pouring concrete, resulting in concrete leakage, affecting the quality of structural construction, and the appearance of the concrete after removal. Therefore, it is usually necessary to reinforce the external corners of the wall to prevent expansion of the formwork.

[0003] In the prior art, a reinforcement device for the anti-expansion formwork at the external corner of a shear wall, with publication number CN212249183U, is constructed by inserting a reinforcement sleeve onto the double steel pipes of the main back ribs, and then passing a positioning and fastening bolt through the reinforcement sleeve to press against the steel pipes to secure the reinforcement sleeves. However, relying solely on the positioning and fastening bolts and the friction between the reinforcement sleeve and the steel pipes can easily cause slippage, resulting in unsatisfactory positioning and fixing effects. Furthermore, if the force exerted by the bolts against the steel pipes is too great, the steel pipes can easily be deformed and damaged, thereby reducing their service life. Therefore, this application proposes an anti-expansion formwork reinforcement device to prevent the occurrence of this problem. Utility Model Content
