An assembly system for making sectional structures, particularly for fair or shopping constructions is provided with a load-bearing section (1) that is provided from outer side with longitudinally extending grooves (2) and in its central region it is provided with at least one gripping chamber (7, 48), as well as with at least one clamping lock (9, 51) serving for attaching other load-bearing sections (1) or parts of the assembly system. The section (1) can be placed inside the gripping chamber (7, 48) the cross section of which match the cross section of the clamping lock (9, 51), and it has two clamping hooks (17) that can be unlocked by means of a control eccentric and serving for hooking in an undercut groove of another load-bearing section (1). At least one gripping chamber (7, 48) for at least one clamping lock (9, 51) is integrated in an adapter (6, 36, 46, and 57) that is inserted in guides (30, 45) directed inward the load-bearing section (1). There are arranged bore holes (12)passing through the guides (30, 45) an intended for inserting therein securing means mediating axial locking of the adapter (6, 36, 46, 57) in the guides (30, 45). The adapter (6, 36) is provided with side holes (14) for attaching control eccentrics (15) of the clamping lock (9) or clamping locks (9). |
