Abstract: A wall construction panel 1 for the setting up of walls for exhibition stand construction includes four frame elements 2, 3, 4, each of which having a groove and being connected to a rectangular frame with a peripheral frame groove pointing to the frame inside. The frame groove is formed by the grooves of the frame elements 2, 3, 4 and a panel 5 is inserted into the frame groove. Two of the four frame elements 2, 3, 4 are configured as frame elements 2, 3 extending in a vertical direction Y, one of which is configured as a pillar element 2 and the other one as an edge element 3. Two others of the four frame elements 2, 3, 4 are configured as framework elements 4 extending in a horizontal direction X where each of the framework elements 4 bears with a horizontal end on the pillar element 2 and the edge element 3 is placed with a first horizontal section 31 between the framework elements 4 and projects with a second horizontal section 32 horizontally over the framework elements 4.

Abstract: The angle connector (100) has two free ends (110, 120) aligned perpendicular to each other, for the purpose of being inserted into an associated cavity of a supporting profile (10, 20), such that at every free end (110, 120) of the angle connector, a passive means of fixation (131, 132, 133) is provided, via which from one outer side of the supporting profile (10, 20), the respective end of the angle connector can he detachably connected to the associated supporting profile by way of a complementary active fixation element (40, 44). Between the free ends that are aligned perpendicular to each other, a corner element is provided, with profile elements (111, 112) compatible with the supporting profiles provided on its two outer sides that are positioned perpendicular to each other, respectively reaching until the height of the associated surface (55) of the corner element (110).

Abstract: The invention relates to a cube-shaped profile element provided with more than six identical side surfaces, wherein preferably eight slots are arranged at an angle of 45 degrees to each other around an axis of symmetry of the side surface and wherein a central boring is provided. Through the slots behind the side surface, insertable closing elements can be inserted through the slots behind the side surface. The profile element is preferably hollow and is constructed from six identical plates that form side surfaces. All the plates are provided with eight-cornered edges, whereby the plates are connected via one edge and the other edges each form an opening at the corners of the cube-shaped profile elements. Very modular, stable construction systems are produced using these elements and cross-shaped profile strips having an acceptable appearance when connected with clamp profiles, wherein these elements each form an optically acceptable closure at the edges of the skeleton structure.
