  • Patent number: 8833019
    Abstract: The present invention provides a lath furring strip having a height not exceeding 0.365 inches which has a flexible elastic water resistive barrier (e.g. rubber) to minimize water seepage from the plaster on the lath to a structure behind the lath furring strip and a hemmed mounting leg to increase the strength of the mounting leg near the lath attachment hole. By incorporating a flexible elastic water resistive barrier into the lath furring strip, when the flexible elastic waterproof barrier on the lath furring strip is squeezed by the force of a screw or nail that secures the lath furring strip to a sheathing or moisture barrier (such as building paper), any holes in the sheathing or moisture barrier which might have allowed water to seep from the plaster to the sheathing will be sealed due to the properties of the flexible elastic water resistive barrier covering those holes.

    Abstract: A composite construction panel having a thin panel of concrete material and a reinforcing grid of sheet metal studs with embedment portions which are actually embedded into the concrete panel, each of the studs having a web, main web openings through the web, a right angular flange formed on a free edge of the web, an embedment angled flange portion formed along the opposite edge of the web, an edge strip formed on the angled flange at an angle thereto; and, spaced apart angled flange openings formed in the angled flange for flow of concrete therethrough. An alternate form of stud has a triangular tube structure along one edge of the web. Another form of stud has a discontinuous webs defining spaces between them. In one embodiment two concrete panels may be secured to the studs in spaced relation to create a hollow structure.

  • Publication number: 20020157340
    Abstract: A brick or other structural member is provided for use in building a wall or other similar structure which is to be provided with a cementitious surface coat application to one, typically exposed, face. The brick includes a relief pattern or profile on at least one face. This allows the installer to adequately affix an external cementitious surface coat to the outer surface of, a brick wall, while also providing a “depth gauge”, which can identify proper coating thickness during installation, which not only ensures proper application thickness but can preclude waste due to overapplication. The added brick texture (a.k.a. profile) increases the surface area of the brick to improve the bonding of the brick surface coating and to provide mechanical underpinning for the surface coating.

  • Patent number: 6393789
    Abstract: A refractory anchor and method of use. The anchor is made by combining two similar sections that are clinched together to form an elongated X-shape. The bilateral symmetrical shape affords maximum anchorage of the refractory, and through-flow of the refractory is afforded by voids through the anchor. The anchor has feet that attach to the surface to be protected, thus allowing refractory to migrate under the anchor. The similar sections can also be used alone as anchors where placement area is limited or irregular. In an alternative embodiment, the anchors have only center feet, to allow them to be stud welded. The anchors are useful in both repair work as well as new refractory applications.

  • Patent number: 6378263
    Abstract: A wall patching device for attachment to the inside of a wall adjacent to a hole in the wall to fill and patch the hole. The wall patching device includes a rigid plate having a plurality of holes therein, the plate having two wings connected by a raised center portion. The raised center portion preferably has a tether connected thereto for holding the wall patching device when the wall patching device is inserted into a hole in a wall or wallboard such as a hole made by a door knob striking a wall.

  • Patent number: 6363679
    Abstract: Fastening devices of this invention comprise a screw and a spacer element. The spacer element can be cylindrical in shape and includes a central opening extending between opposite axial surfaces. One or more grooves are disposed within and extend diametrically along at least one axial spacer surface. The groove is adapted to accommodate a wire section of a wire lath. The screw includes a head at one axial end positioned adjacent the spacer groove, and a tip at an opposite axial end for penetrating and engaging a surface of an adjacent structure. The head includes an enlarged diameter section that extends radially outwardly therefrom a sufficient distance to cover at least a portion of the groove when the mounting means is disposed within the central opening. The fastening device is used to attach a wire lath to another surface by placing a wire section of the wire lath within the spacer groove, and driving the mounting means into the other surface.
