Definitions

• the present invention relates to a mounting rail for mounting plate-shaped elements, such as for instance gypsum boards, and a method for mounting plate-shaped elements at an angle to a support surface, such as a wall, a ceiling or the similar.
• Channels, tubings, cable ladders and similar objects inside buildings often needs to be enclosed with for instance gypsum boards for fire safety reasons or esthetical reasons.
• Said objects are often placed under a ceiling or in wall corners.
• the work to enclose these objects is at present carried out by fastening crossbars of wood or sheet-metal in ceiling or wall, for instance by means of nails, screws or the similar, whereupon suitably cut gypsum boards are secured to the crossbars by screws. After the mounting of the gypsum boards, sealing, puttying, painting etc. is carried out.
• the object of the present invention is to make possible a simplification of the work to mount gypsum boards and other plate- shaped elements, for instance at an angle to a wall or a ceiling.
• said object is achieved by means of a mounting rail provided with a groove designed to receive an edge section of a plate-shaped element, which groove has two essentially parallel sidewalls intended to bear on either side of the plate-shaped element when en edge section thereof is inserted into the groove, at least one of said sidewalls being provided with holding members, which protrude from the associated sidewall into the groove and are intended to penetrate into the plate-shaped element when it is pressed into the groove in a direction towards the bottom of the groove so as to thereby hold said edge section in place in the groove.
• the plate-shaped element When mounting a plate-shaped element using a mounting rail according to the in- vention, the plate-shaped element is intended to be placed with an edge section extending along the groove of the mounting rail in order, subsequently, to be pressed into the groove in a direction towards the bottom of the groove.
• the plate-shaped element Due to the penetration into the plate-shaped element of the holding members protruding from the sidewall, the plate-shaped element will automatically be held in place in the mounting rail when the edge section of the plate-shaped element is pressed into the groove, which considerably facili- tates the mounting work.
• the respective holding member has a cutting edge, which is intended to cut into the plate-shaped element when en edge section thereof is inserted into the groove.
• the penetration of the holding members into the plate-shaped element is facilitated.
• the respective holding member consists of a cutting tooth, which preferably is angled obliquely outwards from the associated sidewall in the direction towards the bottom of the groove.
• the cutting tooth is suitably, as seen in a projection against the associated sidewall, tapered in the direction towards the bottom of the groove so that the end of the cutting tooth facing the bottom of the groove forms a sharp tip.
• the respective holding member is formed by punching of the associated sidewall.
• the respective holding member is formed by punching of the associated sidewall.
• the bottom of the groove is provided with through holes in order to make possible a fastening of the mounting rail to a support surface, such as a wall, a ceiling or the similar.
• one sidewall of the groove of the mounting rail has a shorter extension perpendicular to the bottom of the groove than the other sidewall, the shorter sidewall having a flange at its end facing away from the bottom of the groove, which flange is angled obliquely outwards from the sidewall, the angle between the flange and an extension of the sidewall being between 10- 90°, preferably between 30-45°.
• the oblique flange facilitates the insertion of the edge section of a plate-shaped element into the groove.
• the flange is provided with a through hole for fastening the mounting rail to suspension members, such as hooks or the similar.

• a first gypsum board 1 is here mounted to a support surface in the form of a wall 4a with the aid of a first mounting rail 2 and a second gypsum board 1 is mounted to a support surface in the form of a ceiling 4b with the aid of a second mounting rail 2.
• Said first and second mounting rails 2 here have identical de- sign.
• the gypsum boards 1 are joined to each other at their outer edges with the aid of a mounting rail 3 of corner-type, i.e. a mounting rail which forms a corner of the unit formed by the assembled gypsum boards.
• Gypsum boards mounted in the manner illustrated in fig 1 could for instance be arranged to en- close one or several pipes or other elongated objects.
• the gypsum boards are mounted to enclose a channel extending in the horizontal direction. It is, however, realised that gypsum boards mounted in a manner corresponding to the manner illustrated in fig 1 as well could be arranged to enclose a channel extending in the vertical direction, for instance in a wall corner, or in any other direction.

• the plate- shaped element is conceived to be constituted by a single gypsum board, but the inventive mounting rail could also be dimensioned for mounting a double gypsum board or for mounting a plate-shaped element of another material than gypsum.
• the es- sentials of the inventive solution are that the holding members of the mounting rail, which holding members are described in the following, shall be capable of penetrating into the plate- shaped element when it is pressed into the groove of the mounting rail. Consequently, the inventive mounting rail is in- tended for mounting plate-shaped elements having a certain softness.

• the distance between the two sidewalls 7a, 7b shall consequently essentially correspond to the thickness of the plate-shaped element that is to be inserted into the groove 6.
• the sidewalls 7a, 7b are joined to each other by a rib forming a bottom 9 of the groove 6. At least one of the sidewalls 7a, 7b of the groove is provided with holding members 10, which protrude from the as- sociated sidewall 7a, 7b into the groove 6. These holding members 10 are intended to penetrate into the gypsum board 1 when it is pressed into the groove in a direction towards the bottom 9 of the groove.
• both sidewalls 7a, 7b of the groove 6 are provided with holding members 10 of the type in question.
• the holding members 10 are distributed along the length of the mounting rail, preferably with regular mutual interspaces, i.e. with regular interspaces between adjacent holding members.
• the respective holding member 10 is suitably located somewhat above the bottom 9 of the groove so that there is a certain interspace between the bottom 9 of the groove and the lower end of the holding member facing the bottom of the groove.

• an edge section 1 a of the gypsum board 1 is placed along the groove 6 of the mounting rail.
• the gypsum board 1 may at first be placed obliquely in relation to the sidewalls 7a, 7b so that an edge 1 b of the board rests against the longer sidewall 7b, whereas a lateral surface 1 c of the board bears against the flange 13 of the shorter sidewall 7a, as illustrated in fig 2. Thereafter, the board is turned in the direction of the arrow 14 from the position illustrated in fig 2 to a position where the other lateral surface 1 d of the board will bear on the longer sidewall 7b.

• the holding members 10 are intended to penetrate into the plate-shaped element, they should be relatively stiff so as not to bend away too much when the plate-shaped element is pressed into the groove 6. If so considered suitable, the holding mem- bers 10 may have a small flexibility so that they in addition to penetrating into the plate-shaped element also are bended somewhat when the plate-shaped element is pressed into the groove so that they produce a certain retaining clamping effect perpendicular to the lateral surfaces 1c, 1 d of the plate-shaped element.
