Abstract
Device for joining together building boards, such as floor boards, edge surface to edge surface. It comprises a groove (2) in the rear side of each board (1), the groove running over the entire length of the board parallel to its jointing edge, and a substantially U-shaped spring device (3), the legs (5) of which are adapted each to engage the groove of one board, and which is prestressed so that, upon said engagement, the boards are tightly clamped together edge surface to edge surface.
Description
DEVICE FOR. JOINING TOGETHER BUILDING BOARDS. SUCH
AS FLOOR BOARDS
The present invention relates to a device for join¬ ing together building boards, such as floor boards.
For tight jointing of building boards, especially wooden floor boards, tongue-and-groove joints and glue are normally used. The laying of such boards is time- consuming because glue application is indispensable if a tight joint is to be achieved and, furthermore, the glued boards, once they are laid, cannot easily be taken up again. The object of the invention is to provide a joint¬ ing device allowing simple and convenient laying of boards and also rapid dislodge ent and exchange of, for example, a damaged board.
According to the invention, this is achieved by means of a device which is characterised in that it comprises a groove in the rear side of each board to be jointed, the groove running over the entire length of the board parallel to its jointing edge surface, and a substantially U-shaped spring device, the legs of which are adapted each to engage the groove of one board, and which is prestressed so that, upon said en¬ gagement, the boards are tightly clamped together edge surface to edge surface.
The invention will be described in more detail below, reference being made to the accompanying drawing, in which Fig. 1 shows partly broken boards from behind, jointed by means of the device according to the inven¬ tionj Fig. 2 shows the arrangement of Fig. 1 as seen from the side, and Fig. 3 shows a U-shaped spring ele- ment.
The wooden boards 1 are provided in their bottom side with milled grooves 2 running parallel to and over the entire length of the board edge surface, abutting
against one another in the assembled board arrangement, i.e. the floor. The cross section of the grooves 2 pre¬ ferably is inclined towards these edges from the rear side of the boards. The legs of a U-shaped spring band, made of e.g. steel and having a substantially flat web, engage each with one groove 2 of each board. The spring is prestressed such that the legs thereof tightly com¬ press the boards edge surface to edge surface. In addi¬ tion, the board edge surface preferably form a tong- and-groove joint 4.
One leg 5 of the spring 3 preferably is so designed that its cross section is complementary to the inclined cross section of the grooves. During laying of the boards, this leg is first inserted in its groove in one board, and then the other leg, which also is directed inwardly, is snapped into its groove in the other board. As will appear especially from Fig. 2, the web of the spring band is in contact with the rear side of the jointed boards. Several such spring devices may be arranged in spaced apart relation along the boards.
It will be evident that the invention allows a tight jointing of boards while making the joint arrange¬ ment invisible on the upper face of the floor.
