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

  • The present invention relates to a device for joining 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 jointing device allowing simple and convenient laying of boards and also rapid dislodgement and exchange of, for example, a damaged board.
  • SE-B-372 051 discloses a jointing system, primarily for floor boards. The jointing system comprises building boards and a device for jointing them together, the boards having 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 the device being substantially flat band with upstanding ends each engaging the groove of one board. The jointing system further comprises an elastic jointing seal which should be driven into the joints between the boards from the visible top face thereof in order to make the joints seem justified in functional or aesthetic respects.
  • According to the invention, the device is a spring prestressed so that, upon said engagement, 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 invention; Fig. 2 shows the arrangement of Fig. 1 as seen from the side, and Fig. 3 shows a spring element.
  • 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 preferably is inclined towards these edges from the rear side of the boards. The upstanding ends of a substantially flat spring band, made of e.g. steel engage each with one groove 2 of each board. The spring is prestressed such that the ends thereof tightly compress the boards edge surface to edge surface. In addition, the board edge surface preferably form a tongue-and-groove joint 4.
  • One end 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 end is first inserted in its groove in one board, and the other end, 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 arrangement invisible on the upper face of the floor.

Claims (2)

1. A combination of building boards, such as floor boards, and a device (3) for jointing them together, the floor boards having a groove (2) in the rear side of each board (1) to be jointed, the groove running over the entire length of the board parallel to its jointing edge surface, and the device being a substantially flat band with upstanding ends (5) each engaging the groove of one board, characterized in that the device (3) is a spring prestressed so that, upon said engage- . ment, the boards are tightly clamped together edge surface to edge surface.
2. Device according to claim 1, characterised in that the cross section of the groove (2) is inclined towards the said edge surface, and that the cross section of one end (5) of the device (3) is complementary to the cross section of the groove (2).
