  • Patent number: 10132091
    Abstract: A compliant trim for use between concrete slabs is disclosed, intended to seal the joints and provide a decorative cover over the forms. The compliant trim is placed on the forms prior to the pouring of concrete. The compliant trim contains features which anchor the compliant trim to the slab at numerous points along its length, thereby constraining the compliant trim against any shrinkage effects, and doing so in a manner that introduces minimal stress concentration into the slabs. When the compliant trim is anchored to both of the adjacent slabs, it is capable of following slab motions due to thermal expansion or other environmental effects. The surface of the compliant trim may be used to support the screed. Additionally, the compliant trim may be used to produce a chamfered or radius edge, thereby eliminating the need to radius-trowel the slab.

  • Patent number: 9546456
    Abstract: A slip dowel tube and elongate dowel are disclosed herein which allow for transverse and longitudinal movement of two adjacent concrete slabs and also limit vertical movement of the two concrete slabs. The slip dowel tube is housed within a sheath that provides a void to allow for transverse movement of the slip dowel tube when the first and second slabs move transversely with respect to each other. The elongate dowel is slidably disposed within the main tube to allow for longitudinal movement or movement which brings the two slabs closer to or further away from each other.

    Abstract: A method for creating a tapered spiral welded conical structure where the overall shape of the cone is first graphically slit axially and unwrapped, and then a series of construction arcs and lines are created to form the edge lines of a strip that can then be wrapped (rolled) to form a tapered conical structure. The edges of the spirally wound strip can be welded together, and a very large conical structure can thus be achieved. Various construction options are presented from a constant width strip to strip made from straight segments. Equations are given for the formation of the strips to enable those skilled in the art of spiral welded tubing to practice the invention.

  • Publication number: 20110170950
    Abstract: This invention relates to a monolithic foundation (1) system with homopolymer/resist ant aggregate pavement with a semi-continuous configuration, which uses a pavement with load transfer elements (5) for the induction of joints. It is essentially characterized in that it comprises a foundation (1) having high-density expanded polystyrene blocks, which supports a semi -continuous cement concrete pavement, the pavement formwork being formed by the polystyrene blocks of the foundation. Each one of the load transfer plates (5) is comprised of two anchors (6) with two rebars (7) for alignment of a joint inductor (8), and a ball joint (9) which, at the load support moment, rotates anticlockwise and, at the support moment generated by the load transfer plates, performs a clockwise movement.

    Abstract: A pavement joint 101, 102 disposed between two contiguous pavement slabs 103, 104 and 105 incorporating a shear key (12, 13, 22 and 23) and at least one hinge (37, 38, 39 and 40). The shear key and the at least one hinge are operative when at least one of the slabs is subjected to out-of-plane action P with the shear key transferring shear between the slabs, and the at least one hinge accommodating angular displacement of the slabs relative to the joint axis in at least one direction. In one form, a joint member 10, 20, 40, 50 and 60 is disposed between the slabs to provide the shear key and hinge. A joint member and pavement slab for use in the joint is also described.

  • Patent number: 7845131
    Abstract: A crack inducer controls propagation of cracks in set concrete containing reinforcing bars. The crack inducer has an elongated, rigid core that is relatively narrow in a direction that is parallel to outer surfaces of the concrete. The core has a core width in a first plane that intersects the outer surfaces of the volume, that is at least 20% of the concrete volume width so that a crack in the volume of concrete is induced to propagate from the core and along the first plane. A plurality of spaced cross-plates are connected to the core and a water-stop may be included around part of the core.

  • Patent number: 7571581
    Abstract: A concrete slab where the maximum width value of the slab Dx is determined by the lower measure between the distance D1 of the front wheels of a model loading truck or by the mean, and the distance D2 of a rear running gear of the same truck or the mean; the maximum slab length L is determined by the distance between the truck axles or the mean; and the thickness E is determined by the concrete resistance value, in view of anticipated traffic loads, the kind and quality of the base, and the ground type. The design methodology of this concrete slab allows for only one wheel or only one running gear of the truck to touch and move over the slab.

  • Patent number: 7547158
    Abstract: An expansion joint and the corresponding method of setting an expansion joint between adjacent slabs of poured concrete. To form the expansion joint a filler strip is provided. To protect the filler strip, a protective cap element is provided. The protective cap element has a top surface and opposing side surfaces. The structure of the protective cap element creates a long central groove. Pin corrals extend from the side surfaces of the protective cap element. The protective cap element is placed over the filler strip so that the filler strip is disposed within the groove. The protective cap element and the filler strip are anchored by driving anchor pins through at least some of the pin corrals. Concrete is then poured against the filler strip and the protective cap element, wherein the concrete envelops the pin corrals that are not engaging anchor pins.
