Abstract: In order to simplify the production of sealed wall connections in the case of raised floors, especially to allow the disassembly of the floor tiles (11) even in the area of the connected wall (10), the wall (10) carries on its bottom edge (20) one or more socket profile rails (21). The socket profile rails (21) are supported on upright support members (31) provided at least on posts (12). However, it is also possible to support the socket profile rails (21) on profiles in the form of rectangular pipes which are laid out in the grating on the posts (12). The bottom (24) of the socket profile rail (21) extends from the middle in opposite directions obliquely outwardly and upwardly.

Abstract: In order to decrease the number of different structural elements required and to expedite the assembly of a rapid-construction framework as a support structure for ceilings and wall plates of a building, modular connections are used, each having four shaped guide bars, for connection of supports with tie bars of the rapid-construction framework, which are brought into force- and form-locking engagement with the hollow spaces of the supports or hollow main elements at the ends of the tie bars, for the assembly of the framework. Main elements, which are hollow on the tie bar side, are of the same dimensions and are welded in the same manner to the ends of the tie bars. A leveling member 40 is of diameter to that of the supports.
