A structure (2) for erecting walls comprises a number of abutting lateral surfaces (10, 10', 10"), external lateral surfaces (11) and two horizontal surfaces (12). At least one blind recess (13) is provided in the lateral surfaces (12) with a surrounding closed wall surface. The or each blind recess (13) is arranged at a separation from the edge of a front abutting lateral face (10') corresponding to one of the halves of a grid separation. At least one blind recess (13) is embodied with a wall surface with flat sections tapering inwards which abut against each other along edges. Boundary surfaces (14) for a pointing joint are arranged along a line running parallel to an external lateral surface (11) at a separation corresponding to half a wall thickness. A modular, more precise with regard to pointing joints and more stable construction of a wall is thus achieved. |
