    Abstract: The floor member is a laminated structure of flexible compressible cork sheet material and flexible plastic sheet material in the form of a floor tile or a floor plank. The cork sheet material and plastic sheet material are offset, from each other and have respective predetermined thicknesses to enable the floor member to be bendable to facilitate assembly of a plurality of the floor members into a floor covering. The compressible cork sheet material provides sound and heat insulation and the flexible plastic sheet material is yieldable to surface irregularities of a floor base. The cork sheet material is sandwiched between two layers of clear plastic material to provide a distinct sight of the structural presence and thickness of the cork sheet at an edge of the floor member.

  • Patent number: 8100380
    Abstract: An igloo building block mold comprises a shell defining a pair of generally cuboid mold portions. The mold portions are offset from one another in both an upright direction extending between the top and bottom ends of the mold portions and a lateral direction extending between the end walls of each mold portion. A building block formed by the mold, when stacked on a previous row of blocks, permits inter-engagement between the blocks due to a shoulder being formed on each block which engages the corresponding shoulder of a previous block supported therebelow. The offset in the lateral direction permits side edges of each block to be inter-engaged with adjacent blocks as the blocks are placed in the desired position in the igloo structure during construction.

  • Publication number: 20020028114
    Abstract: The present invention relates to an interlocking masonry wall block having an open core and spaced projections that enable stacked blocks to be interlocked, setback and staggered to form a stable gravity-type retaining wall that is particularly suited for landscaping applications. The open core extends completely through the block from top to bottom. The block is formed by front, rear and opposed side walls, each having parallel inside and outside surfaces. One projection extends from the lower surface of each side wall. The front of each projection is forward the inside surface of the front wall to provide the setback when stacked on other like-shaped blocks. Each block is stacked in a staggered manner atop two other blocks. One projection of each block is received by the open core of one of the two lower blocks. The projections abut the inside surface of the front wall of the lower blocks to interlock the blocks together.

  • Patent number: 6145267
    Abstract: An interlocking block for constructing walls without mortar at bed joints includes an inner wall, an outer wall, and a web arrangement connecting the walls, wherein upper and lower surfaces of the block when in use are formed in contact with walls of a mold, and the block is slipped from the mold in a direction parallel to the mold walls. Interlocking recesses and ridges are formed in one piece with the walls of the block. The web is minimal in cross-sectional area and is positioned at one end of the block and between the top and bottom to create large empty volumes defining vertical and horizontal passages. The block can include one or more intermediate walls parallel to the inner and outer walls and additional webs to connect the intermediate walls to the inner and outer walls.

  • Patent number: 6119418
    Abstract: A construction panel is formed of a plurality of elongate subpanels where each subpanel comprises a plurality of expanded polystyrene blocks placed end to end. Tensioning cables pass over the inner and outer surfaces of the subpanels between tensioning plates positioned at each end of the subpanels. Tensioning the cables imparts longitudinal compression in the subpanels, such that the blocks of the subpanels act monolithically. The inner and outer surfaces of the subpanels are longitudinally convex. The panel may be corrugated. The subpanels may be interlocking to form the construction panel.

  • Patent number: 6024517
    Abstract: A concrete slab for forming blocks for a retaining wall comprises a prism having parallel top and bottom surfaces, and opposed parallel side walls, and end walls, the prism has an X axis in the longitudinal direction extending between the end walls, a Y axis in the width direction extending between the side walls, and a Z axis perpendicular to the X and Y axes extending between the top and bottom surfaces. A first dividing line extends parallel to the X axis from one end wall to the other end wall in order to define a separating plane bisecting the prism. At least a pair of dividing lines extend parallel to the Y axis of the prism from the first dividing line to each of the opposite side walls, wherein the second dividing lines are parallel to each other but offset therefrom, whereby upon separating the slab along the first and second dividing lines, at least four blocks in the form of rectilinear prisms having different dimensions in the X axis will be formed.
