PCT No. PCT/SE78/00017 Sec. 371 Date Mar. 19, 1979 Sec. 102(e) Date Mar. 13, 1979 PCT Filed July 11, 1978 PCT Pub. No. WO79/00047 PCT Pub. Date Feb. 8, 1979 The constructional member is intended for use in installations of falce ceilings, walls, doors and windows in buildings, and is formed as a substantially U-shaped rail with a web portion (1) and two leg portions (2, 3). Since one leg portion (3) is shapable onto the web portion (1), the rail can be first placed round the member (15) which is to be erected, e.g. a partition wall, and thereafter the constructional member can be fixed in place with the help of the snap-on leg portion (3). The middle portion (5, 7, 8) of the web portion (1) has channels which enable exact fitting of the constructional member either round a building member (17) or against another constructional member, e.g. at corners or edge surfaces. The member can be fixed against the ceiling and floor at an optional location in a room, which substantially simplifies installations and alterations. Further advantages are that all installations can be carried out as pure erection work and that the material which is used in an installation can be recovered and reused on being dismantling. |
