摘要:
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 fasteners 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 fasteners comprise a lower portion and an upper stand-off portion. The lower portion is operatively coupled to 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 portion is heat treated to a higher degree of hardness relative to the remainder of the stand-off screw.

The composite joist floor system includes joists supported by supporting members. Corrugated steel decking is positioned over the joists such that the corrugations are substantially perpendicular to the joists. Self-drilling, self-tapping, stand-off screws are spaced along the length of the joist, aligned with the deck corrugations. These stand-off screws provide the required shear transfer between the joist and concrete slab to form a composite floor system. The placed concrete encapsulates the upper non-threaded shank portions of the stand-off screws and the end of the joists. After the concrete has cured, the resultant system comprised of steel joists, steel decking, stand-off screws, and concrete, act together to form a composite system with greater load carrying capacity and less vertical deflection. The stand-off screws connect the joist upper chords to the concrete slab allowing the joist and concrete slab to act as a unit, by transferring shear between the two joined components.

The possibility of special lightening, insulating and reinforcing intermediate floor constructions enables fast building of semi-prefibraceted and prefabricated floor with complete insulation, bearing capacity and smaller price. Floor elements and are constructed to that already present steel space trusses can be placed in their channels, so that are hastened the building of intermediate floor constructions and makes them cheaper, too. They are minimum shorting at the ends and at the middle of beams, so the works below can be proceeding and the required working time is shorter. The intermediate floor construction is already insulating, so they are no need for insulating, which makes the construction cheaper and the required working time shorter. The plates are enabling the increase of the height of the floor constructions, by tying two beams in the construction. Usage of distance elements and protects the reinforcement in floor construction, so they are no need for corrosion protection.

A SYSTEM FOR PRODUCING FLOOR CONSTRUCTIONS EXTENDING ACROSS A SPAN BETWEEN UPRIGHT WALLS WHEREIN CONSTRUCTION BLOCKS ARE ALIGNED IN INDIVIDUAL ROWS IN SIDE-BY-SIDE RELATIONSHIP. A SUPPORTING STRUCTURE IS PROVIDED FOR HOLDING INDIVIDUAL BLOCKS AS THEY ARE PLACED IN POSITION TO FORM A ROW. ELONGATED TENSIONING MEMBERS ARE APPLIED TO EACH ROW WHILE STILL ON THE SUPPORT WHEREBY THE BLOCKS IN THE ROW ARE SUBJECTED TO COMPRESSIBLE FORCES MAKING THE ROW SELF-SUSTAINING. THE SUPPORT CAN BE MOVED AFTER APPLICATION OF TENSION AND REPEATEDLY USED FOR SUCCESSIVE ROWS. A GROUTING MATERIAL IS DISPOSED IN THE OPENINGS DEFINED BETWEEN ADJACENT ROWS OF BLOCKS WHEREBY THE TENSIONING MEMBERS WILL BE EMBEDDED IN THE GROUTING MATERIAL BETWEEN THE ADJACENT ROWS.
