The lattice member is positioned relative to the upper and lower steel bars in a way such that the holding rib parts, individually having a foot part, are alternately positioned on opposite sides of the upper and lower steel bars. A vertical fixing steel bar is welded to each end of the deck girder with both the top end of the fixing steel bar being welded to the upper steel bar and the middle portion of the fixing steel bar being welded to the lower steel bar.

  • Patent number: 5996303
    Abstract: A truss that, in one embodiment, includes alternating metal webs in non-critical portions of the truss is described. The truss includes two chords vertically spaced apart and parallel to each other, and a plurality of metal web members extending between the two chords and coupled to the vertical surfaces of the chords. The truss also includes at least two critical portions and at least one non-critical portion. The critical portions of the truss are configured so that the metal webs coupled to each side of the truss are aligned, and each metal web coupled to one side of the truss has a corresponding metal web coupled to the other side of the truss. The non-critical portions of the truss are configured so that the metal webs coupled to one side of the truss do not have a corresponding aligned metal web coupled to the opposite side of the truss.

  • Patent number: 5927036
    Abstract: A floor joist system for building construction comprising interconnected steel girders and joists. The girders may be castellated I beams having a plurality of large openings and regularly spaced vertical slots through its web, which extend between opposite side walls of a building or its foundation, supported thereby. Joists may be I beams of shorter height than the girders which have tongues formed from their webs which extend from their ends. The tongues of two joists are fitted into a single vertical girder slot from opposite sides of the girder, their tongues overlapping therein. The opposite ends of the joists are similarly fitted into an adjacent girder or rest upon a side wall of the building or its foundation. The girder slot is positioned and the side walls are adapted such that the uppermost surfaces of the joists and the girder(s) are coplanar.

  • Patent number: 5915745
    Abstract: Grid-shaped reinforcement strip is configured for reinforcing masonry joints, and includes at least one substantially straight elongated reinforcement wire having a substantially rectangularly cross section. There is a further reinforcement wire having a substantially rectangular cross section that is spaced apart from the at least one reinforcement wire. At least one connecting wire extends between opposed faces of such at least two spaced apart reinforcement wires. An unflattened weld attaches the at least one connecting wire to respective ones of opposed faces of such at least two reinforcement wires. The connecting wire preferably has a substantially round cross section, and the thickness of the at least one connecting wire is as thick or less thick than the thickness of the at least two reinforcement wires.

  • Patent number: 5809726
    Abstract: A building system and apparatus for forming a wall on a footing. U-shaped channels and H-shaped or T-shaped members coupled at their sides by rigid links hold foam panels in a desired spaced relationship. Vertically oriented panels aligned and connected by T-shaped members or horizontally oriented panels stacked with and connected by H-shaped members are inserted into the U-shaped channels to form a structure of the desired length. Concrete is poured between the panels and members where it hardens to form a structural wall. The planar surfaces of the U-shaped, H-shaped and T-shaped members enable the members to be extruded, thereby substantially reducing member production costs. Furthermore, widely available conventional foam panels can be used, reducing panel production costs.

  • Patent number: 5761873
    Abstract: A self-jigging web for fastening two steel chords together to form a beam. There are different sizes of webs for assembly of beams of different depths. A web has several holes for locating screws for fastening the web to a pair of chords parallel to each other. Chords having the same outer cross-section but of different steel gauges are used to obtain beams of different strengths. Assembled beams are used in a frame of a building structure such as a wall, floor or ceiling. A system is provided such that a building designer, given the wind bearing (bending) and axial loads required to be borne by the structure, can determine beam spacing and beam depth required for the structure to bear the loads. Beams are then assembled to meet the determined requirements according to a standard set of instructions which detail the chord steel gauge, size of web, number and spacing of webs lengthwise along a beam, and a number and placement of screws for fastening each web to a pair of chords.

  • Patent number: 5448866
    Abstract: A space truss is constructed of a pair of plane trusses. Each of the plane trusses is constructed of an upper and lower chord member fixedly connected with each other through a strut member interposed therebetween. The thus constructed plane trusses are oppositely disposed from each other in a condition in which the strut member of each of the plane trusses are interposed between the thus oppositely disposed plane trusses, the upper chord members of the plane trusses are closely disposed together, and the lower chord members of the plane trusses are spaced apart from each other. A sheet steel is fixedly connected to the space truss through a hanging hook to form a composite-type space truss. Any of these space trusses are embedded in concrete in the factory to form a precast reinforced concrerte slab.
