  • Patent number: 8424257
    Abstract: A modular tile configured to interlock with multiple tiles to form a modular floor covering over a floor. The tile includes a top surface having a periphery defining side walls extending downward from the top surface, the side walls having a coupling portion configured to couple with other tiles adjacent thereto to form the modular floor covering. The tile also includes a bottom side, opposite the top surface, having a support grid including an array of downward extending polymeric post structures, at least some of the post structures including at least one resilient end portion with a radial end surface configured to be positioned against the floor to facilitate controlled deflection of the post structures.

  • Patent number: 8394219
    Abstract: A method of manufacturing a hollow core door is disclosed, as well as a corresponding hollow core door. The method includes the steps of providing a solid flat door skin, moisturizing the flat skin, applying a conditioning resin thereto, pre-heating the flat door skin, and thereafter pressing the flat door skin between a pair of heated platens in a press in order to reform the flat skin into a molded skin including a plurality of panels defined therein. The press continuously closes in order to reform the flat skin into the molded skin, with the rate of press closure being a function of the determined hardness of the flat skin to be reformed. The resulting door skins have an improved bond strength, and are efficiently manufactured.

  • Patent number: 8381473
    Abstract: Connectors for joining adjacent modular floor covering units. The connectors include a film and an adhesive layer coated on one side of the film. To install tiles using the connectors, a first tile is placed on the floor and a connector is positioned so that the adhesive layer faces upward and does not contact the floor. The connector is typically positioned so that only a portion of the adhesive layer adheres to the underside of the tile, leaving the remainder of the connector extending from the underside of the tile. Tiles are then positioned adjacent the first tile so that a portion of the connector adheres to the adjacent tiles. In this way, the connectors span adjacent tile edges. The tiles are assembled on a underlying flooring surface without the need to attach them to the floor surface. Rather, the tiles are linked to each other with the connectors, so that the tiles create a floor covering that “floats” on the underlying floor surface.

  • Patent number: 8327590
    Abstract: A support assembly for supporting a retrofit roof to be installed above an existing roof made of preformed panels. Elongated support assembly members are positioned along the roof line to provide additional points of attachment for the new roof, while at the same time forming a substantially even plane for new roof panels. Some of the support members fit in the channels between the ridges of the preformed panels, which can be R-panels or standing seam panels. Transverse top members secure the channel-mounted members in place, while strapping members positioned atop the top members form additional lateral support for the new roof. A plurality of bracket support assemblies is secured between the top members to the roofing panels to elevate the new roof support. The bracket support assemblies are formed of two engageable parts to increase resistance to wind forces.

  • Patent number: 8136315
    Abstract: A connecting device for curtain wall units is disclosed. The connecting device comprises: a claw arm having a horizontal arm for carrying the curtain wall units; a plurality of clamping plates, each two clamping plates fixed on the horizontal arm to clamp the curtain wall units; and a claw base connected to the claw arm and a supporting structure of the curtain wall units. The weight of curtain wall is supported by the claw arm of the connecting device, and point-supported type clamping of the curtain wall is realized by the clamping plates on the end of the claw arm, which enables the stability and security of the structure of curtain wall. The claw arm is hidden in the space between the curtain walls, and thus the whole appearance of curtain wall is beautified. Furthermore, it is unnecessary to provide through holes on the glass wall units.

  • Patent number: 8122671
    Abstract: An improved building structure and method for making steel frame buildings includes a beam-to-column or beams-to-column joint or connection which is most preferably shop fabricated (as opposed to on-site fabrication) and which offers a considerable savings in both steel requirements (i.e., material savings) and labor to make the joint connection. Also, because material utilization is improved in the connection, the new structure is more resistant to damage by seismic events (i.e., earthquake), by severe weather, and to damage from blast effects (i.e., terrorist attack or accident), than was the prior technology. The improved building structure also mitigates against progressive collapse of the building.
