Description

Technical Field

[0001] The utility model belongs to the technical field of concrete construction formwork, in particular to a concrete construction formwork support frame. Background Art

[0002] The main function of concrete formwork is to shape and support the newly poured concrete, while also protecting and improving the surface quality of the concrete.

[0003] In concrete construction, ground pouring is a key step, which involves pouring the concrete mixture into the designated area and properly compacting and leveling it. The concrete construction formwork plays a vital role in ensuring the concrete pouring process. The formwork not only maintains the correct shape of the concrete during the pouring process, but also protects and maintains it during the concrete hardening process. In order to enable the formwork to withstand the weight and lateral pressure of the newly poured concrete during concrete pouring, and to ensure that the formwork will not deform or collapse during the construction process, a concrete construction formwork support frame is designed. The support frame can provide lateral support to the formwork through the cooperation of the supporting base plate, the contact plate and the support rod. At the same time, the support plate can change the height of the support rod, thereby enhancing the lateral support force of the contact plate on the formwork, that is, when the concrete is poured, the formwork can withstand the weight and lateral pressure of the newly poured concrete, and to ensure that the formwork will not deform or collapse during the construction process.
