  • Patent number: 7010889
    Abstract: A riser clamp mateable with a riser, wherein the riser clamp supports a column of the riser as material passes therein, and the riser clamp further covers or seals the opening in the partition formed through which the riser passes. The riser clamp comprises a pair of clamp members adjoined to a riser. The clamp members comprise a semi-annular jacket seated against the riser, a collar circumscribing the jacket, wherein the collar covers an opening formed in a partition through which the riser passes. The clamp members further have a pair of mounting flanges depending from the jacket and the collar, with the mounting flanges extending laterally in opposing directions from the jacket and coplanar to a medial margin. Each one of the mounting flanges accommodates a fastener for adjoining the pair of clamp members securely about the riser.

  • Patent number: 6957896
    Abstract: The invention relates to the provision of apertures in building board materials, such as in ceiling or walls. A first aspect relates to an aperture edging member for forming a substantially smooth or “flush” aperture within a surface member. The edging member includes a substantially planar rim portion adapted to be attached to the surface member, a lip provided along one edge of the rim, and a flange depending from the lip in a substantially transverse direction to the rim so as to fit within the aperture. The second aspect relates to an aperture edging device which has an intermediate section with a pair of arms depending transversely therefrom to form a substantially c-shaped configuration to envelope the edge portion of the surface member. An advantage is that a strong rigid vertical face is created in the plaster board, minimizing the possibility of damage thereto. Light fittings, or other fittings may be associated with the device.

  • Publication number: 20040060249
    Abstract: A support module for interconnecting to like support modules serves to support a number of core elements for encapsulation within a concrete structure. The module has a planar frame defining a first cutout and a second cutout. Each cutout has an arc shape, such that the cutouts from different modules define a circular aperture for closely receiving one of the core elements. The frame has extending portions with connection elements that connect with other support modules to securely receive the core elements. The extending portions are located about the periphery of the frame so that they are able to connect to other support modules in four orthogonal directions.

  • Patent number: 6694684
    Abstract: A cast-in-place pass through firestop device for providing a passage in a partition through which wires, cables, pipes, and the like are run includes a housing having a riser portion with frangible connections that define removable bands that can be readily removed by a user to adjust the height of the device in accordance with the thickness of the partition into which the device is installed. The removable bands include pull tabs that provide grasping means to facilitate removal of the bands by a user along a frangible connection. The housing also includes a base portion including a recess with ribs for maintaining firestop material in spaced relation from the base portion sidewall. A flame retardant char forming material, which works in combination with the firestop material to provide a fire, smoke, and water barrier, may also be provided adjacent the firestop material.

  • Publication number: 20040016191
    Abstract: A frame for bordering conduit access through a building floor has a rigid body portion and a lining of intumescent material on an interior surface of the rigid body portion. The intumescent material has sufficient expansion capacity to close off the opening through the frame under conditions which produce an intumescing of the lining. The rigid body portion itself is preferably made of a metallic material to enhance transfer of heat energy from the rigid body portion to the lining of the frame.

  • Patent number: 6637166
    Abstract: To enable vehicles such as truck tractors, motor homes and recreational vehicles to receive electrical power and communications when parked, a power and communications assembly is provided. A base is mountable in an exterior surface of the vehicle openings through the base are defined for mounting a respective connection moiety so each mounted moiety can be engaged with a complementary connection moiety when a main cover for the base and the mounted moieties is opened against a bias causing it to be normally closed. The connection moieties mountable in the base openings are selected from a group which includes electrical power connectors, telephone circuit connectors, and connectors for coaxial cables and fiber optic cables. Features of either a base opening or a mounted connection moiety can be engaged by its own secondary cover; the several secondary covers when engaged can be accommodated with a space protected by the main cover when it is closed.

  • Patent number: 6629396
    Abstract: A manufacture or cell (20) formed by a closed case (21) of fabric material (23) in which a multiple number of meltable plastic pellets (24) are disposed and with which an electrical line (25), here in the form of lines (25-1, 25-2), combine in an interwoven assembly. Heat is applied to the pellets (24) via the electrical line (25) to melt them into a mass of substance that solidifies into a solid wall or thickness while concurrently adhering to the fabric material (23) so that the resulting structure is in a cast condition, transformed from its flexible state prior to application of the heat to pellets (24) into a wall-like member. The cell (20) is useful in application of constructing a habitable temporary living housing or shelter for victims arising out of a catastrophe.
