  • Patent number: 10653464
    Abstract: A foot bone plate provides both fixation of two bones or bone portions and compression across their juncture. The foot bone plate has a plurality of bone screw bores positioned to receive and hold a bone screw on both sides of the two bones/bone portions (i.e. fixation), and a lateral flange positioned to receive and hold a bone screw across the foot bones/foot bone portions juncture (i.e. compression). The foot bone plate has an elongate body having a plurality of bores along its length configured to receive and hold a bone screw generally perpendicular to the foot bone plate and into the two foot bone portions. A flange is positioned at a side of the plate and includes a bore to receive and hold a bone screw. The flange and flange bore positions and holds the bone screw such that it extends through the juncture of the two bones/bone portions.

    Abstract: The present apparatus and method relates in general to sealing a hole in a floor with a precast plug. A precast plug is created by pouring a wet aggregate mix into a form mold and thereafter inserting a pre formed rod into the uncured mixture, positioning it such that the center of the rod rests in the center of the form mold and the ends of the rod extend outward near the top of the form mold. The mix is then cured. The precast plug may then be transported to the hole that it is destined to fix. Grooves may be carved on either side of the hole to accommodate the rod' s ends. The interior of the hole and the exterior of the plug may then be covered with a sealant, after which the plug may be inserted into the hole. Once the sealant cures, the hole is fully repaired.

  • Patent number: 9663950
    Abstract: A concrete component includes a fiber reinforcement structure (12), formed by a grid arrangement (15). At least some of the rods extending in the X or Y direction are preferably designed as double rods having a joined cross-section or having sub-cross-sections separated from each other by a gap (20). Such double rods can be arranged in a grid structure both at right angles to each other and at other angles to provide a triangular structure, a hexagonal structure, or the like as a grid. Fiber reinforcement structures (12) made of a plastic-impregnated fiber material, such as epoxy-resin-bonded glass fibers having long fibers (endless fibers), in the particular rod longitudinal direction and without bonding among each other (ravings) can construct an adequately load-bearing composite with the concrete body (II). The steel rods can act as reinforcement, wherein harmful effects on the concrete, in particular wedge and gap effects, do not occur.

  • Patent number: 8745957
    Abstract: The induced macro-cell corrosion prevention method includes the step of replacing a corroded or chloride-contaminated section of a steel reinforcement or rebar in steel-reinforced concrete with a new rebar section free of chloride. A non-conductive insulating buffer is placed between the end sections of the new rebar and the corresponding end sections of adjacent chloride-contaminated rebar sections in order to form a non-conductive layer between the new steel and the old steel. This prevents or substantially reduces formation of a macro-cell that would cause a galvanic reaction to occur and increase corrosion potential.

  • Patent number: 8726600
    Abstract: A concrete re-entrant corner crack inhibiting device for implantation into a re-entrant corner of a casted concrete structure serves to inhibit stress fractures from developing at the cured concrete re-entrant corners. The device includes a re-entrant corning brace for cornering and embedding onto the re-entrant corner, a radial arm radiating outwardly from the brace so to extend into the cement structure and a fracture interrupting unit transversely connected to the radial arm so as to intercept, interrupt and inhibit the development and spread of stress fractures emanating from a cured cement re-entrant corner.

  • Patent number: 8726599
    Abstract: A fatigue load resistant structure includes a fatigue loaded portion and a weldable fatigue loading resistant feature. The fatigue loaded portion includes a first elongation material. The weldable fatigue loading resistant feature includes a second elongation material secured to the fatigue loaded portion of the fatigue loaded structure. The first elongation material is less ductile than the second elongation material, and the weldable fatigue loading resistant feature can reduce, retard, or eliminate formation of cracks due to tensile and compressive forces.

  • Patent number: 8689491
    Abstract: A low cost method and device for diverting water away from a flat roof's low spots, thus preventing it from puddling there during a rainstorm. Such puddles, if allowed to stand, can damage a roof deck structurally. The device includes a flexible membrane, an air valve mounted thereon, and mechanical fasteners for attaching the membrane along its periphery, to both the roof deck and its existing covering. Ideally, the membrane can be heat welded, taped or glued to the roof covering and joined thereto to form an airtight seal, thus simplifying construction of inflatable barriers for the roof's low spots. For each such barrier, a membrane, sized and shaped to cover at least one low spot, substantially overlaps the latter's edges and defines, in combination with the roof covering, an air pocket which, when inflated via the air valve, causes the membrane to protrude upwardly, effectively elevating the covered spot.

  • Patent number: 8661758
    Abstract: A seal assembly (10) is provided for sealing a core hole (52) formed in a concrete slab (54) having opposite first and second surfaces, with the core hole (52) extending between the first and second surfaces. The seal assembly (10) comprises a cover assembly (12) having a cover plate (14) that is configured for engaging the first surface of the concrete slab (54) and seating over and covering the core hole (52). The cover assembly (12) has a lower plate (16) that is configured for being received within the core hole (52). The lower plate (16) is coupled to the cover plate (14) through a support member (20) so that the lower plate (16) is spaced apart from the cover plate (14) when the cover plate (14) is seated over the core hole (52) to define a cavity between the lower plate (16) and the cover plate (14). A locking element carrier (26) is coupled to the cover assembly (12).

  • Publication number: 20130312354
    Abstract: The present apparatus and method relates in general to sealing a hole in a floor with a precast plug. A precast plug is created by pouring a wet aggregate mix into a form mold and thereafter inserting a pre bent rod into the uncured mixture, positioning it such that the center of the rod rests in the center of the form mold and the ends of the rod extend outward near the top of the form mold. The mix is then cured. The precast plug may then be transported to the hole that it is destined to fix. Grooves may be carved on either side of the hole to accommodate the rod's ends. The interior of the hole and the exterior of the plug may then be covered with a sealant, after which the plug may be inserted into the hole. Once the sealant cures, the hole is fully repaired.
