PCT No. PCT/SE97/01679 Sec. 371 Date Apr. 8, 1999 Sec. 102(e) Date Apr. 8, 1999 PCT Filed Oct. 8, 1997 PCT Pub. No. WO98/16702 PCT Pub. Date Apr. 23, 1998A beam construction for ceilings in clean rooms, comprising first (1) and second (2) beams. The first and second beams are arranged essentially horizontally and perpendicularly to each other and have longitudinal ducts (7) for receiving a liquid or viscous sealant. In order to facilitate mounting and increase the flexibility of the beam construction, a transition piece (12) is arranged between two beam elements (1a, 1b) which are arranged successively in the longitudinal direction, thereby forming an opening (14) in at least one side-limiting duct wall (6) of the first beam (1). A second beam (2) is arranged sealingly against the transition piece (12) and the first beam elements (1a, 1b) arranged on each side thereof, such that the ends of the duct walls (6) of the second beam encompass the thus-formed opening (14). |
