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.

A constructional member for use with prefabricated building elements used in ceiling, wall, door, and window installations, comprising a base rail with a substantially U-shaped cross section having a web portion and two leg portions of resilient material, one of said leg portions being releasingly attached to one end of the web portion by means of resilient engagement between latching members arranged on these portions, wherein the base rail is provided with two supporting limbs opposingly directed in relation to the leg portions, the outer distance between the supporting limbs corresponding to the inner distance between the leg portions, so that the base rails can fit into each other, and in that the central part of the web portion is formed with two U-shaped attachment rails with a common web portion and opposingly directed shank pairs which together with the attachment web portion define similar channels, in which building members and/or clamping elements of the constructional member is insertable; including a fastening element associated with the constructional member and consisting of a clamping rail which is U-shaped in cross section and provided with a web portion and two shanks, the height of which from the outer surface of the web portion facing away from the shanks substantially corresponds to the height of the supporting limbs of the base web portion and that the web portion of the clamping rail is also formed with two gripping elements which are at the ends provided with hooks and intended for engagement with the shank ends of the attachment rails.
