Abstract: An insulated wall panel is provided that employs a plurality of spaced insulated members that define cavities within the body of the wall panel. The insulation panels that form the cavities may be constructed of a reinforced insulating material, such as expanded polystyrene. The insulated wall panels may include a reinforcing mesh, preferably fiberglass coated with PVC embedded within the body of the EPS foam during fabrication. The strengthened EPS foam blocks have the advantage of being lightweight and very durable, thereby reducing handling damage, for example.

Abstract: The present invention relates to an apparatus and method for selectively dispensing reinforcement material into a concrete component. The apparatus is capable of providing, positioning and embedding any form of rolled reinforcement materials into both prefabricated concrete components and cast-in-place concrete components which can be operated by a minimal number of personnel in a timely and economical manner, and which can be used to mass produce concrete components.

Abstract: A wall panel is provided that is comprised of a plurality of spaced foam insulative blocks. Between each block is a metal stud that spans the height of the wall panel and provides sufficient strength to counteract any compressive loads the wall panel may encounter. The presence of the insulation panels provides large surface areas for the receipt of a thin layer of cementious or gypsum based material that is adapted to receive nails and be easily cut. In addition, the decreased weight of the exterior wall allows for the omission of reinforcing internal structure within the exterior wall which is found in the prior art, thereby providing a lightweight and easy to fabricate wall.

Abstract: An insulative, lightweight building panel is provided with a lightweight, insulative foam core and which includes one or more carbon fiber or steel reinforcements and an exterior concrete face which are manufactured in a controlled environment and can be easily transported and erected at a building site.

Abstract: The present invention relates to an apparatus and method for selectively producing a deformation in a reinforcing frame employed in the fabrication of concrete pipes or other similar construction materials. The deformation maintains the frame in the proper predetermined location inside the concrete form during fabrication to thus produce a concrete pipe with optimum structural properties.

Abstract: An insulative, lightweight concrete building panel is provided with one or more fiber or steel reinforcements which are manufactured in a controlled environment and can be easily transported and erected at a building site.

Abstract: An insulative panel with transverse fiber reinforcements is provided and which is adopted for use with a plurality of building materials such as concrete to create a lightweight, high strength building panel having superior insulative properties.

Abstract: The present invention relates to building panels used in the construction industry, and more specifically composite building panels comprised of an insulative core, concrete, and carbon fiber which are preformed, cast and transported to a building site for modular construction.

Abstract: A precast concrete modular device using thin coffered sections reinforced preferably with carbon and/or glass fiber scrim grids, in between steel reinforced ribs is provided. The thin reinforced sections stiffen the steel reinforced precast frame. The thin sections preferably have a thickness less than about two inches, preferably less than about 1½ inch, and more preferably less than about 1 inch. The resultant modules have an areal weight of less than about 40 lbs. per square foot.

Abstract: The present invention discloses a precast railway crossing slab adapted to extend transversely across the surface of conventional railway ties, with slots or gaps dimensioned and disposed to receive a pair of railway rails therethrough. The crossing slab includes a post-tensioning system in which metal cable strands or tendons are sheathed within plastic tubes and are positioned in the slab mold frame prior, to pouring of concrete. Tendon anchors are also disposed in the slab mold frame prior to pouring. After the concrete hardens, a hydraulic jack is used to tension and anchor the tendons in a stressed condition, thus providing reinforcement to the slab. The railway crossing slab of the present invention may be utilized with or without surface or edge metal plating. Flange way fillers which typically comprise rubber strips extending between the sidewalls of the metal rail and the concrete slab may optionally be employed.
