  • Patent number: 8721219
    Abstract: An attenuating element includes a head part, neck part and base part. The neck part is narrower compared to the head part and neck parts of adjacent attenuating elements form a continuous channel. Via the head parts, this channel is connected so that the cross-sectional area of the head parts is smaller than the cross-sectional area of the base parts. In this way, a water-control structure, sound-attenuating wall and the like can be provided. Such attenuating elements can be produced in a very simple manner by dividing them vertically and producing each of the vertical parts from concrete in a mould.

    Abstract: A block for use in constructing a retaining wall. The block has a bottom with a non-planar portion that forms a gap between the block and the top surface of a lower course of similar blocks when the block is placed thereon. This gap allows the block to rest on the lower course of blocks in a stable, level manner by providing a space that can accommodate small amounts of intrusive material such as rubble, dirt, or miscellaneous debris which would otherwise interfere with the stacking of the blocks. The block's bottom may also include a plurality of grooves that provide additional clearance in the gap for larger bits of intrusive material such as pebbles or small stones. Preferably, the grooves have angled walls which act to funnel the larger bits of intrusive material into an area of adequate clearance when the block is being placed on a lower course of similar blocks.

  • Patent number: 6910305
    Abstract: A system for walls and structural slabs is disclosed. It consists of units of a pre-case reinforced concrete element has a special form design, fabrication methods and utilisation. The element has a circular section, variable lengths and flat surface on the top and bottom sides (2). It has a sectional area of 4170 sq mm. The optimum preferred dimensions of the cross section are 64 mm high and 75 mm wide (1). The element has an optimum shape that reduces the materials used yet provides the structural performance required. When stacked vertically between two structural framing columns, the elements form non-load-bearing walls system(3). The elements form structural diaphragm when horizontally laid side by side in a butt-jointed manner, supported on both ends by means of structural framing beams. Plain concrete topping to the necessary thickness is cast over the diaphragm/elements, forming an integral reinforced concrete structural slab system (4). The elements are fabricated mechanically or manually.

  • Patent number: 6907703
    Abstract: A five-sided interlocking block. At least one side, and preferably at least three sides, of the block is adapted to engage the same side of a similar block to interlock the blocks. At least one side of the block may also be adapted to rotatably engage the same side of a similar block. At least three sides of the block may also include anti-shear receptacles. The anti-shear receptacles on any side of two blocks may be aligned and shear prevention components inserted therein to interlock the blocks. The block may further include an optional interior space, enabling the block to be used as a container for appropriate material.

  • Patent number: 6898906
    Abstract: A ground covering element having the basic shape of a square. All four basic sides of the around covering element have an engaging profile, each profile being symmetric with respect to a central axis of symmetry. Opposite engaging profiles are mirror images. Each engaging profile is complementary with the adjacent engaging profile. Each of the four corner regions of the ground covering element of a first type have a protrusion substantially the shape of a rectangular, isosceles triangle or of an area element similar to this triangle with curved legs. A ground covering element of a second type (42) is obtained by omitting the four protrusions from the ground covering element of the first type. The ground covering element of the second type may be laid together with additional ground covering elements of the second type or in combination with ground covering elements of the first type.

  • Patent number: 6893192
    Abstract: A retaining wall block system is described. The block system includes blocks of different sizes that are configured to be compatible with each other in the construction of a retaining wall or free-standing wall. Each block has at least three faces which are textured to produce the appearance of natural stone. The faces have varying sizes based on variations in width.

  • Patent number: 6877290
    Abstract: A plurality of building blocks (1) form a retaining wall (300), which may be curved, with respective side edges (6, 7) providing pivot points and a stepped base (5) of an upper block (1) being positionable on the upper surface (4) of a lower block (1). The gaps between the blocks 1, and their permeability, being made from permeable concrete, can avoid hydrostatic build up behind the wall (300). The permeability of the concrete used for the blocks (1) is in the range of 10?2 m/s to 10?4 m/s and may be in the region of 6.00×10?3 m/s.

  • Patent number: 6874293
    Abstract: A cast concrete block for use in a vertical retaining wall. The block has a generally vertical front face which is visible when the block is stacked in a retaining wall. A pocket is formed in the block to project from a portion of the visible face of the block. The pocket has an upwardly directed opening which is exposed for receiving soil and plants when the block is located in a vertical retaining wall. The opening may extend through the block to a rear of the block.

  • Patent number: 6854231
    Abstract: A retaining wall block system having multiple sizes and shapes of blocks with differently dimensioned, interchangeable front and back faces. The blocks are used to construct an irregularly textured wall having a weathered, natural appearance. Multiple channels in the lower face of the block are used to engage pins in pin-receiving apertures to form an attachment system. Horizontal reinforcing members are also used in the channels and vertical reinforcing members are used in cores of adjacent blocks for reinforcing a wall. Reinforcing geosynthetic materials can also be firmly held in a wall by means of the pins or by connectors adapted to fit in the block channels.

  • Publication number: 20040250495
    Abstract: Precast concrete paver blocks are provided with interlocking edge joints so that abutting edges of adjacent paver blocks align when the blocks are installed and are maintained in alignment. At each joint, each block includes a tapered projection and a recess. When edges of two blocks are moved to abut each other, the tapered joint projection on each block enters the joint recess on the other block. The taper on the projections move the blocks to align the block surfaces. The edges of the blocks are angled or relieved below the joints to ensure a tight fit at the top of the paver blocks.
