  • Patent number: 10196818
    Abstract: An apparatus used in roof construction wherein insulation material is held flush within the channels formed by the apparatus. The flush engagement between the insulation material and the walls defining the channels of the apparatus leads to a greater surface area securing the insulating material in place. The apparatus includes attachment means on its top flanges to mount rebar members to the apparatus holding the rebar grid in place. The vertically disposed flanges of the apparatus include openings that allow concrete to pass through the apparatus preventing fatigue points caused by the interruption of concrete. The apparatus can be employed in a method that allows a roof to be transported to a job site with the rebar grid already secured to an apparatus.

  • Patent number: 8230657
    Abstract: 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.

  • Patent number: 6128878
    Abstract: A concrete floor of a portable storage building is made for one or more storage units with each unit including a floor made through use of a single pair of mold sections or a plurality of pairs of mold sections interconnected for multiple storage units. Each mold section has a raised center and a circumferencial channel with concrete being poured onto the raised center and into the circumferencial channel. Removable exterior mold side walls complete the floor mold. A jack bracket is removably attachable to the floor corners and in turn is engageable with a hydraulic jack for raising and lowering the floor for loading onto the flatbed of a truck for transport to a remote site of use. A chain hoist connected to a top edge of a building wall panel is used to pivot the wall panel to a raised vertical position as the hoist moves on a rail to the vertical plane of the wall panel when raised.

  • Patent number: 6094878
    Abstract: A composite floor structure comprises a mortar layer set by a mineral agent and a carrier plate adjoining the lower surface of the mortar layer. The carrier plate has upwardly projecting structural members extending into the mortar. The dimensions of the mortar coating over the structural members are so low that the structures created in the mortar by the structural members represent weak areas. When stresses arise in the mortar layer, joint face assemblies connecting weak areas are formed to reduce stress in a uniform manner. By forming different joint face assemblies, a joint face structure is produced, wherein to reduce stress, the stress causing the mortar to fracture only results in a low level of longitudinal change in each individual joint face. Consequently, each individual joint face only takes the form of a microcrack.

  • Patent number: 6009678
    Abstract: A virtual block for pre-fabricated slabs for replacing cement, ceramic or expanded foam blocks during the erection and finishing work of slabs having a flume with longitudinal and angled moldings. The flume is fabricated with corrugated sheets. Rib-butts are positioned at the side of the flume and are grooved so as to promote the embedding of lattice ends. The rib-butts are angled structures with shapes and external measures that are exactly equal to the internal shapes and measures of the flume in such a way that when the lattices are encased in the interior of the flume, the flume becomes structured and gains strength opposing any orthogonal forces. The lattices incorporate side expansions to indicate their orthogonality in relation to an axis of the flume. Holes are distributed in a surface of the lattices.

  • Patent number: 6006483
    Abstract: A deck panel for reinforced concrete slabs is disclosed. The deck panel is formed by integrating a plurality of deck girders with a deck plate into a single structure. In each of the deck girders, a single lattice member is welded to upper and lower steel bars. The lattice member has a zigzag configuration with both a plurality of holding rib parts and a plurality of horizontal foot parts. 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: 5934036
    Abstract: An insulated concrete slab assembly for use over expansive soils. A slab is cast in place by pouring concrete into preshaped insulating forms. The forms remain permanently in place and provide insulation to reduce heat transfer through the slab. The shape of the forms provides strengthening ribs on the slab. The ribs act as beams which allow the slab to bridge or cantilever over expansive soil between foundation walls. The forms are supported during construction by support members or legs which later prevent damage to the slab by eliminating or limiting the forces which can be applied to the slab by expanding soil.
