Abstract
The flooring is made up of a set of touching parallel floorboards (10) and is supported by a set of mutually parallel load-spreading plates (2) placed on the ground via a resilient underlayer on which they rest; the flooring is remarkable by the fact that said floorboards (10) are stuck to said plates (2) by means of beads of elastically-deformable adhesive (4) such as polyurethane placed on the top faces of the plates (2), preferably in respective longitudinal grooves (3) formed in the top face of the plates. The invention relates to flooring, in particular for playing sports.
Claims7
1/ Flooring with floating support, the flooring being made up of a set of touching parallel floorboards (10) and being supported by a set of mutually parallel load-spreading plates (2) laid on the ground via a resilient underlayer (5) on which they rest, the flooring being characterized by the fact that said floorboards (10) are stuck to said plates (2) by means of beads of elastically-deformable adhesive (4), such as polyurethane, disposed on the top faces of the plates (2).
2/ Flooring according to claim 1, characterized by the fact that said beads of adhesive (4) are received in longitudinal grooves (3) formed in the top faces of the plates (2).
3/ Flooring according to claim 2, characterized by the fact that said grooves (3) are substantially rectilinear in section, being dimensioned in such a manner that after the bead of adhesive (4) has been flattened and has set, it occupies a fraction of the inside space of the groove (3) in which it is received.
4/ Flooring according to claim 2 or claim 3, characterized by the fact that the plate (2) is provided with a single middle groove (4).
5/ Flooring according to any one of claims 1 to 4, characterized by the fact that said plates (2) are oriented in such a manner as to form an acute angle (α) relative to the longitudinal direction of the floorboards (10).
6/ Flooring according to claim 5, characterized by the fact that the angle (α) has a value of about 45°.
7/ Flooring according to any one of claims 1 to 6, characterized by the fact that the floorboards (10) are assembled to one another by a tongue-and-groove engagement system (100, 101), possibly together with glue.
