Description

Technical Field

[0001] The utility model relates to the technical field of building boards, in particular to an adjustable formwork wall. Background Art

[0002] Formwork walls are a type of prefabricated building element that are often used to replace traditional brick walls to simplify the construction process and improve building efficiency.

[0003] The process of making the formwork wall requires selecting a suitable mold, pouring concrete or other materials in the mold, and demolding and subsequent assembly of the wall after the concrete solidifies. Existing metal formwork walls such as the Chinese patent publication number CN209523377U are made by pouring concrete between the male plate and the female plate, so that the metal formwork wall can be poured on the construction site, but the formwork wall cannot adjust the pouring size. When a formwork wall of another thickness needs to be poured, the mold needs to be redesigned and made, which is difficult to reuse.

[0004] Therefore, in view of the above problems, an adjustable formwork wall is proposed to solve the above problems. Utility Model Content
