Abstract

A prefabricated board, such as gypsum board or fiber board, with a facing of paper, fabric, plastics or like material affixed thereto, is provided with an edge corrector strip which is fastened along the edge of the board before the facing layer is adhered thereto. The strip preferably is of L-shape and one limb portion thereof lies flat against the rear side of the board while the other limb portion thereof lies along the edge face of the board, the facing material being wrapped or folded about the edge corrector strip.

Difficulties have been encountered hitherto in mounting such wall lining boards because of their uneven edges which make the joints between two boards or between a board and an adjoining surface uneven and untight. This also contributes to deteriorating the sound insulation so that sound readily passes through the walls, and to giving the joints a less pleasing aesthetical appearance.
These deficiencies are overcome by the wall lining board according to the present invention. The characteristic novel features of the boards reside in that edge corrector strips are arranged within the finished surface layer of the boards and are formed by substantially L- shaped bars one limb portion of which is secured to the rear side of the board while the other limb portion extends along the edge surface of the board.
The invention will be described more in detail hereinbelow with reference to the accompanying drawing in which:
FIG. 1 is a view of the joint between two lining boards designed in accordance with the invention;
FIG. 2 is a front view of the edge corrector strip proper;
FIG. 3 is a cross section of said strip.
1 denotes the wall lining board proper which in the present instance comprises a core 2 of gypsum or like material which is enclosed by a layer 3 of cardboard or paper. The lining board 1, which may be a gypsum board, is provided on its surface facing the room with a surface layer 4 which may be a wall paper or like material. The surface layer is attached to the gypsum board already during manufacture and is wrapped or folded about the edges of the board so that the edge surface also is entirely covered by the surface layer. To obtain an even and tight joint between the boards which are often uneven at the edges, an edge corrector strip 5 is mounted along the edge of each board. The
edge corrector strip 5 is disposed between the cardboard layer 3 enclosing the gypsum and the surface layer 4 which is wrapped or folded over the edge of the strip, thus resulting in a tight and even joint. The edge corrector strip is preferably fastened by means of tubular rivets 6 or like elements. Fastening bars 7, 8 can then in turn be fastened to the edge corrector strips by drive screws or like elements.
The edge corrector strip 5 the design of which appears more clearly from FIGS. 2 and 3 consists of a bar of L-shaped cross section. The limb portion which is arranged to provide the seal is designated 9, while the limb portion by which the strip is to be fastened to the gypsum board is designated 10. The portion 10 is formed with holes 11 to permit fastening thereof to the gypsum board by means of tubular rivets or like elements. The angle between the portions 9 and 10 is preferably somewhat obtuse, which permits the upwardly bent portion 9 to flex somewhat against the edge of the board, which contributes to providing a satisfactory seal. The width of the upwardly phenpp orness 0 e ining tlon 9 is preferably equal to the thic board, but may be slightly larger or smaller, if desired.
In certain instances where an edge correction is not required, a strip being only in the shape of the portion 10 can be employed for the fastening of the gypsum boards. Such a strip will in that case constitute a screwed force-distributing fastening for e.g. selftapping screws, drive screws or like fastening means, thereby preventing the gypsum board from being damaged. To make use of the portion 10 in this manner will be advantageous in that the number of fastening points at the edge of the gypsum board is reduced, there are increased possibilities of applying different fastening methods since various supplementary and mounting strips can be secured in the portion 10, the gypsum board is more reliably fastened, and mounting of the gypsum board will be facilitated.
Modifications may be resorted to within the scope of the appended claims. Thus the edge corrector strips need not be fastened together with the suspension device but may be fastened separately. The angle between the two limb portions can be varied, and the strip can be mounted also on boards devoid of a finished surface layer.
What I claim and desire to secure by Letters Patent 1. A prefabricated lining board, such as gypsum board or fiberboard, which is intended for mounting on partition and like walls and are provided on the surfaces facing the room with a finished surface layer in the form of wall paper or like material, wherein edge corrector strips are arranged within the finished surface layer of the board and are formed by substantially L- shaped bars one limb portion of which is secured to the rear side of the board while the other limb portion extends along the edge surface of the board.
2. A lining board as claimed in claim 1, wherein the two limb portions of the L-shaped bar make a slightly obtuse angle with one another.
3. A lining board as claimed in claim 1, wherein the limb portion serving as a seal is resilient in relation to the limb portion serving to fasten the L-shaped bar.
