Assembly type building wallboard

Abstract

The invention discloses an assembly type building wallboard. The wallboard comprises a building girder, the building girder is arranged in a longitudinal symmetry mode, the two sides of the building girder are connected with an inner wall and an outer wall, a cavity is formed between the inner wall and the outer wall, the cavity is filled with a heat preservation layer, and the inner wall and theouter wall are connected through a plurality of buffer pieces. Compared with the prior art, the wallboard has the advantages that the inner wall and the outer wall are connected to the two sides of the building girder to form the cavity, and the cavity can be filled with the heat preservation layer or the heat preservation layer can be formed in the cavity by pouring, so that a good heat preservation effect is achieved; and the building girder is connected to the ends of the inner wall and the outer wall, and the buffer pieces are connected between the inner wall and the outer wall, so that aconnection effect is achieved, the connection stability, the impact resistance and the energy dissipation capacity of the inner wall and the outer wall are improved, the overall ductility of the wallboard is greatly improved, the phenomenon that cracking is prone to occur is improved, and the service life of the wallboard is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of building wallboards, in particular to a prefabricated building wallboard. Background technique [0002] With the acceleration of urbanization in my country, prefabricated buildings have ushered in a new opportunity for development. Compared with cast-in-place construction, prefabricated construction has the advantages of convenient construction, fast project progress, little impact on the surrounding environment and easy guarantee of the quality of building components, so it has received extensive attention and research at home and abroad. Prefabricated wall panels are generally prefabricated by beams and wall panels, and the beams and wall panels form a whole. [0003] However, the existing prefabricated wall panels often have a single function, are highly brittle, have poor ductility, poor energy dissipation capacity, and are prone to cracking or even collapse.
