Abstract:
A support mat includes a plurality of vertically oriented individual wood members adhesively bonded to each other, each of the individual wood members having wide faces oriented parallel to a direction of a load applied to the support mat, the support mat having outboard wood members, the outwardly facing wide faces of the outboard wood members defining a wide face of the support mat. The support mat also includes least two protective edge members, each protective edge member having an inboard wide face, each of the at least two protective edge members positioned against one the wide faces of the support mat. At least two substantially rigid fasteners extend through and connect each of the protective edge members and adjacent wood members. The wood members, protective edge members, and fasteners define a substantially rigid support mat having a substantially planar wide face.
Abstract:
An interlocking construction block has opposed ends each having a plurality of substantially planar bearing surfaces. The planar surfaces include perpendicular surfaces joined by surfaces at obtuse angles. The block is arranged to be complementary to other blocks in several different configurations.
Abstract:
A systems for a permeable pavement system is described. The permeable pavement system includes blocks designed to facilitate water seepage between the blocks and to permit water storage within the blocks. The blocks may be unified together with the use of a cable inserted through each block to create paving units that facilitate installation and maintenance of the pavement system. The paving units may be moved with loops on the ends of the cables. Multiple paving units may be linked together with lock blocks.
Abstract:
The present invention relates to a road restoration block for covering eliminated pavements during various road constructions conducted by eliminating some of or the entire existing road pavements, and more specifically, to a road restoration block, which can quickly and safely cover the eliminated pavements by providing blocks that are simply carried, disposed, and disassembled with strong coupling power to the upper part of the eliminated pavements so that people and cars may pass even when the constructions are in progress, thereby providing a safe and pleasant construction environment by preventing the traffic congestion caused by the constructions.
Abstract:
A predominantly concrete mat comprises a concrete slab having two longitudinal edges and two transverse edges and having relatively thicker portions and relatively thinner portions, which include relatively thinner portions among the longitudinal and transverse edges, and a flexible grid embedded in the concrete slab. The flexible grid, which is polymeric, is molded so as to have longitudinally extending members and transversely extending members. End portions of specific ones but not all of the longitudinally extending members of the flexible grid extend into and nearly or completely through the relatively thinner portions along the transverse edges of the concrete slab. End portions of specific ones but not all of the transversely extending members of the flexible grid extend into and nearly or completely through the relatively thinner portions along the longitudinal edges of the concrete slab.
Abstract:
Embodiments of the present invention may be used to form a continuous covered area, such as a sidewalk or patio, by vertically interlocking tessellated components. One embodiment, termed PORTAPAVE™, achieves this interlocking via an array of uniquely configured two-sectioned pavers. Each paver has a first section of a first shape and a second section of a second shape impressed upon the first section and bonded together. In one embodiment, first sections of pavers in an installed bottom layer form a cavity between them having the same shape as the second section of a paver that is inverted onto the pavers of the bottom layer, thus providing a top layer. Each inverted paver in this top layer is fitted to interlock in that cavity formed between the un-inverted pavers in the bottom layer. Also provided is a method of making the components, e.g., pavers, and a method of installing them.
Abstract:
A weldment connector for use with castable concrete slabs, each of the slabs including a length, width and depth and having at least one opposing and extending edge. The weldment connector has a substantially elongated and planar shaped front face and first and second legs which are both integrally formed with and extend from opposite end locations of the front face. The legs further extend in a combined axial and rotationally offset fashion relative the front face and each includes a horizontally extending and vertically spaced apart component with passes either above or below a mesh screen associated with the concrete slab. Additional features of the weldment connector include the width of the extending legs increasing, from a first end associated with the interconnecting and planar shaped front face, to outermost extending ends thereof. Also, pluralities of undulating portions may be formed in substantially width-wise extending fashion and at spaced apart locations along each of the legs and, in combination with the outwardly flaring of the legs, provides for increased gripping and holding forces of the associated concrete slab.
Abstract:
A tile and backing assembly for creating a walkway, pathway and a driveway atop ground. Each assembly used in constructing the walkway preferably includes a backing member formed from a single sheet having elongated tile support members positioned side-by-side one to another. Each tile support member is defined by spaced apart transverse slits or cuts through the backing member, each having complete and incomplete segments and extending in zigzag fashion thereacross. Each of the incomplete segments is defined by overlapping unconnected spaced slit segments to define a slender elongated expansion link connecting adjacent tile support members together. Each of the tile support members have evenly spaced tile attachment areas, each of which supportively receive one of a plurality of tiles. Each tile is attached to one tile attachment area in a desired design array with adjacent tiles abutting one another when the assembly is in the contracted orientation. The assembly is deployable atop the ground by pulling end margins thereof apart to expand the backing member in length whereby the tiles form a desired spaced apart expanded array atop the ground.
Abstract:
A weldment connector for use with castable concrete slabs, each of the slabs including a length, width and depth and having at least one opposing and extending edge. The weldment connector has a substantially elongated and planar shaped front face and first and second legs which are both integrally formed with and extend from opposite end locations of the front face. The legs further extend in a combined axial and rotationally offset fashion relative the front face and so that, upon being embedded within a first selected slab of concrete with front face extending in exposed fashion along its extending edge, the construction of the legs exhibits greater resistance to cracking. In use, a second weldment connector is likewise embedded within a second selected slab of concrete in similar fashion and so that its corresponding front face extends along an opposing extending edge, in proximate fashion relative to the front face of the first weldment connector. A conventional weldment, such as is provided by an electric weld gun, secures together the front faces of the first and second connectors. In use, the weldment connectors act to redistribute, within the interior body of each concrete slab, load forces applied along its common seamed edge.
