External corner wall component

Abstract

The invention relates to the field of construction, in particular to construction panels for prefabricated buildings and structures, specifically to corner elements of constructional structures. The technical result is to increase the permissible load in a multi-storey building. The corner element is mounted such that the first surfaces face inward of the room. The adjacent wall panel is installed in an L-shaped corner defined by the first lateral surface, the second lateral surface, the third lateral surface and the additional surface. The wall panel is coupled to the corner element. The seam formed at the junction has an L-shaped configuration. The sealing compound is disposed behind the protrusion of the corner element, which has a positive effect on increasing the reliability of joint sealing.

The invention claimed is:
