Embodiments of the present invention provide systems for connecting a flooring system to a vertical wall. In one embodiment the building structure includes a floor comprising a cementitious slab and a wall supporting at least a portion of the cementitious slab. A plurality of stand-off screws extend from the top of the wall into the cementitious slab and are configured to transfer forces between the cementitious slab and the wall. The stand-off screws comprise a lower screw portion and an upper stand-off portion. The lower screw portion is drilled into the top of the wall, and the upper stand-off portion extends above the top of the wall and is encapsulated within the cementitious slab. In some embodiments, at least a portion of the lower screw portion is heat treated to a higher degree of hardness relative to the remainder of the stand-off screw.

Des versions de la présente invention fournissent des dispositifs pour raccorder une structure de plancher à un mur. Dans une version, la structure de bâtiment comprend un plancher constitué d'une dalle cimentaire et d'un mur soutenant au moins une partie de la dalle cimentaire. De multiples vis-entretoises vont du haut du mur dans la dalle cimentaire, et elles sont configurées pour transférer les forces agissant entre la dalle cimentaire et le mur. Les vis-entretoises comprennent une partie de vis inférieure et une partie d'entretoise supérieure. La partie de vis inférieure est percée dans le haut du mur, et la partie d'entretoise supérieure dépasse du haut du mur et est noyée dans la dalle cimentaire. Dans certaines versions, au moins une partie de la partie de vis inférieure est traitée à la chaleur, à un degré plus élevé de dureté par rapport au reste de la vis-entretoise.
