Description

TECHNICAL FIELD

[0001] The present application belongs to the field of building components, and particularly relates to a prefabricated lattice wall. BACKGROUND

[0002] Masonry structures play an important role in rural building projects, but the traditional masonry structure system has technical problems such as poor seismic performance, insufficient thermal insulation capacity, and complicated construction process. In terms of seismic resistance, the traditional masonry structure lacks seismic structural measures, resulting in insufficient seismic resistance of the building. In terms of thermal insulation, the mortar joint structure of the masonry wall is prone to cause cold and hot bridge phenomena, and cannot meet the building energy saving requirements. In terms of construction, the construction of the traditional masonry structure relies on a large number of wet operations, and the construction period is long and the construction quality is difficult to guarantee.

[0003] Fabricated buildings, as a green and low-carbon construction method, have significant advantages in improving construction efficiency and reducing energy consumption. However, the existing fabricated wall structure still faces a series of technical challenges; first, the thermal conductivity of the fabricated wall material is relatively large, resulting in insufficient thermal insulation performance of the wall; second, the assembly precision of the wall is poor, and errors occur during the assembly process, affecting the stability and construction efficiency of the overall structure. Therefore, improving the construction efficiency of the fabricated wall while improving its thermal insulation, seismic resistance, and assembly precision has become a technical problem that needs to be solved in the current construction industry.
