    Abstract: An arcuate building structure containing at least three five-sided building blocks, at least three six-sided building blocks, and means for connecting one of said five-sided building blocks to at least one of said six-sided building blocks. The top side of the six-sided block has a substantially triangular shape, and is substantially parallel to the bottom side of the six-sided block. The front side of the six-sided block has a substantially trapezoidal shape with a top edge, a bottom edge, a right edge, and a left edge. The right edge and the left edge have equal lengths and form equal angles with the bottom edge. The back side of the six-sided block has a substantially triangular shape with at least two sides equal in length to each other. The left and right sides of the six-sided block are congruent with each other, are in the shape of a parallelogram, and contain a recess within their borders.

  • Patent number: 5325652
    Abstract: A building facade material includes a plurality of elongate stone strips held in an abutting relationship on a flexible mesh when in a plane with the flexible mesh enabling the strips to be adhered to a curved surface, with a V-shaped area between strips suitable for grouting, between adjacent elongate stone strips. The elongate stone strips have a thickness which enables the strips to be ground to an arcuate contour without exposing the flexible mesh. A color-matching settable material is provided for grouting the V-shaped areas between the elongate strips. The method for applying a stone facade includes the steps of adhering a plurality of abutting elongate strips of stone attached to a flexible backing over a curved surface, grouting the groutable spaces with a settable material and thereafter grinding the entire composite into a smooth, arcuate, non-seamed, solid-stone appearing arcuate surface or column.

  • Patent number: 5307388
    Abstract: A containment structure (1) for storage of nuclear fuel or liquids which have been in contact with nuclear fuel includes a concrete wall (3) and a concrete floor (2) with a corrosion resistant liner (5) fixed to and in contact with the walls and floor except at the junctions of the walls and floor at which the liner is curved to provide "soft corners" (7) to permit movement of the liner relative to the concrete walls and floor.The term "soft corner" as used in the context of the present specification denotes a region providing a gap or empty space or collapsible or compressible material, eg foam, between the stainless steel liner and the concrete walls and floor. Any collapsible or compressible material employed needs to be stable to the radioactive environment and for this reason it is preferred that a gap or empty space is employed.

  • Patent number: 5303518
    Abstract: A plastic liner for protecting concrete manhole interior surfaces from corrosion wherein the liner includes provisions for creating a strong mechanical lock between the liner and the interior surfaces. A side of the liner which includes the provisions has a plurality of raised hollow projections with spaced sections. The mechanical lock is created when concrete is poured against the side of the liner with the projections. The concrete at least partially enters the hollow portions and fills spaces between the projection sections. The projections also intersect to enhance the mechanical lock by preventing bulging. Liner sections cover essentially all of the manhole interior surfaces. Forming a liner section by rotationally molding the plastic and cutting gaps into the projections is also disclosed.

  • Patent number: 5277580
    Abstract: An improved wall construction system for refractory furnaces is disclosed. The system includes an outer support structure into which are incorporated a plurality of connecting pin receiving sleeves or apertures. The system further includes a plurality of regularly-shaped bricks which have engaging members and receiving cavities on the ends of the bricks and on the upper and lower surfaces of the bricks. The engaging members and receiving cavities are adapted to interlock the bricks relatively to each other to preclude lateral movement. The system further includes a plurality of anchoring members which are adapted to be received between an engaging member and a receiving cavity of adjacent bricks. The anchoring members further extend out from the bricks and include a connecting pin shaped and sized to engage within the apertures in this first support structure in order to anchor the brick wall system to the outer support system in use.

  • Patent number: 5265750
    Abstract: A modular cylinder comprises a plurality of, in this case 24, modules each having a tongue to engage a groove of its neighbor and each either having a camming ramp to engage a camming ramp of its neighbor, or a filler rod inserted between adjacent modules at each interface. Where the camming means are provided, (n-1) of the modules can be placed into engagement to define an almost complete cylinder and can then be strained in a radially outward direction to provide space for the final module which is placed in position by sliding longitudinally of the gap. Where the filler rods are used, all of the n modules may be loosely assembled in a first operation and the filler rods can be inserted in a second operation to pre-stress the cylinder.
