A building construction for floors comprising joists (24) that have vertical, threaded, through-running holes (4) for level-adjusting spacer screws (6), which protrude from the joist on its underside (3) for adjusting the top side (2) of the joist to a desired level, an elastic damping body (26) being arranged at the anterior screw portion (12) and having an outer part (27), which forms a resilient connection between the screw and the substructure (14), and an inner part (28), which is located inside a central hole (8) in the screw (6). In accordance with the invention, the inner part (28) forms a resilient engagement element for co-operation with an inner support surface (36) in the bottom part (10) of the screw. An attachment element (9) for anchoring the screw to the substructure extends through a central hole (33) in the damping body. The cross section of the inner part is greater than the diameter of said bottom part. The invention also relates to joists and screws of the specified kind.
L'invention concerne une structure d'assemblage de sols comprenant des lambourdes (24) qui présentent des perforations (4) traversantes destinées à des vis (6) d'espacement, lesquelles dépassent de la lambourde sur sa face (3) inférieure et permettent d'ajuster la face (2) supérieure de la lambourde à un niveau désiré. Un élément (26) d'amortissement élastique est placé sur la partie (12) antérieure de la vis. Cet élément se compose d'une partie (27) externe qui forme une connexion souple entre la vis et la structure (14) sous-jacente, et d'une partie (28) interne qui est située à l'intérieur d'un orifice (8) ménagé dans le centre de la vis (6). Cette partie (28) interne constitue un élément de contact souple coopérant avec une surface (36) de support interne située dans la partie (10) inférieure de la vis. Un élément (9) de fixation permettant d'ancrer la vis dans la structure sous-jacente passe à travers un orifice (33) central de l'élément d'amortissement. La section transversale de la partie interne présente un diamètre plus grand que celui de la partie inférieure. L'invention concerne également des lambourdes et des vis du type décrit.
