Wall module for building a structure, associated structure and connector system

Abstract

A wall module is configured as a concrete prefabricated building element for building a structure and can be connected to further wall modules to form a structure and is configured to withstand improbable extreme loads. The wall module has a wall body with multiple edges, a plurality of reinforcement rods which all together form a regular reinforcement grid, and each extend parallel to the edges, and which are cast into the wall body. The reinforcement rods each penetrate the wall body substantially from edge to edge, and provided at their ends with connecting elements configured to establish a connection with complementary connecting elements of an immediately adjacent wall element. Each of the connecting elements is connected with clearance to the associated reinforcement rod such that it can be moved in a plane which is perpendicular to the longitudinal direction on all sides by at least 2 mm.
