Abstract (en)

[origin: US5016408A] 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. The seal between the connected wall (10) and the adjacent floor tiles (11) can be formed by elastically flexible gaskets (25) in the form of strips on both sides of the wall (10) or else the longitudinal edges of the socket profile rails are configured to be elastically flexible and engage on the contiguous floor tiles (11) flexibly and with formation of a seal.
