  • Patent number: 5836715
    Abstract: A structural member for reinforcement of asphalt and concrete roadways and other products, and which comprises a gridwork of warp strands and weft strands which are disposed at right angles to each other and so as to define an open structure. In one embodiment, the gridwork is impregnated with a thermosettable B-stage resin so as to interlock the strands at their crossover points and maintain the gridwork in a semi-flexible state, and after being applied to the product to be reinforced, the resin is heated to convert the same into a fully cured composite to thereby rigidize the gridwork and reinforce the product. In cases where the product to be reinforced is heated, such as asphalt paving, the heat of the product provides the heat necessary to fully cure the resin in situ. In another embodiment, the resin is fully cured to rigidize the gridwork prior to its being applied to the structure to be reinforced. A method of producing the resin impregnated gridwork is also disclosed.

  • Patent number: 4996816
    Abstract: A support device for supporting longitudinal rigid members in a poured layer for example rebar within concrete comprises two V-shaped wire elements which are inverted and have parallel rails welded across the elements. Two lower rails are spaced at the end of the legs of the elements to allow the ends of the legs to be inserted into the ground. The elongate members then rest across the upper rails between two apex portions of the elements which extend upwardly above the upper rails. The rails extend out beyond the elements to provide portions which can be inserted into the ground when the device is rotated through 90.degree. to support the elongate members at a different height from the base layer. The use of a wire structure enables the concrete to be poured around the device without the formation of voids. The use of four legs inserted into a sand or similar base provides great stability.

  • Patent number: 4865486
    Abstract: The present invention is directed to a weldless pavement module and a method for making a weldless pavement module. Each of the primary load bearing bars is formed with openings for receiving slotted secondary load bearing bars which are passed through the primary load bearing bars in a substantially horizontal position and which are rotated into a vertical position. The size and shape of the openings and the slots permit the combination of primary load bearing bars and secondary load bearing bars to be skewed to form a nonrectangular parallelogram configuration. Simple tack welds are used to temporarily hold the grating in its desired configuration. A concrete component encases at least the top surface of the grating base member and permanently secures the elements of the grating base member together. The use of tack welds eliminates the requirement that the grating base member be bent into a convex shape prior to welding. A simple flat jig is used.
