Abstract: A wall system for exhibition halls has a plurality of rigid wall elements each having two cover plates, profiles arranged between the cover plates on vertical edges for receiving of coupling elements, the profiles having a longitudinal groove with inwardly conical reducing cross-section, the longitudinal groove having side walls provided with oppositely located longitudinal grooves, the profile being provided with at least one opening arranged at one side selected from the group consisting of an upper end side and a lower end side for receiving a pin or a screw of mounting elements arranged on an edge of the wall element selected from the group consisting of an upper edge and a lower edge.

Abstract: The dividing wall is assembled from a plurality of inherently rigid wall elements (10). A wall element of the wall was a frame composed of vertical frame sides (11, 12) and horizontal frame sides (13, 14), an inner plate (22) suitable for anchoring nails or screws and cover plates (20, 21) which can have a thin construction, a stiffening honeycomb filling (23) being provided between the cover plates (20, 21). The vertical frame sides (11, 12) are provided with a conical external groove (15) or an external spring pin (16) which fits into the latter, so that adjoining wall elements can be put together so as to be self-centering, wherein the reciprocal connection is effected by inserting coupling pegs of one wall element in catch openings of the other wall element. The dividing wall thus is made of lightweight individual wall elements which can be assembled quickly.
