ABSTRACT:
In the technical field of supporting grid walls with a bulk material filling, comprising longitudinal and cross beams which form a supporting grid structure, there is a substantial need for beam structure and shaping making possible enhanced connection stability together with a relatively simple and low-cost production of the elements and with simple mounting methods.
The invention solves this problem by providing at least one hole or recess in the cross beam open over a part of its circumferential contour and adapted to receive a longitudinal beam for establishing a form-locking connection between the beams secured against separation and displacement against each other in a mounted state. The contour of the hole or recess overlaps the upper side of the longitudinal beam so as to form an abutment therefor, and is shaped so as to firstly permit a partial lateral insertion of the longitudinal beam while establishing contact between the abutment and the longitudinal beam in a first rotational position of the latter in relation of the cross beam. The shaping of the hole or recess further permits the full insertion of the longitudinal beam while establishing the form-locking connection easily by cross-sectional rotation impossible to be reversed when the structure is under load.
