摘要:
The invention relates to a paving stone (1), especially for road construction. The paving stone (1) has side flanks (23) preferably directed perpendicularly with respect to the laying plane. At least two coupling members (3, 4) are disposed on at least one side flank (23) wherein the coupling members correspond with the coupling members (3, 4) of an adjacent paving stone (1). At least one coupling member (4) has a width substantially corresponding to the clear width between two adjacent coupling members (3, 4) of an adjacent paving stone (1).

The invention relates to an artificial stone floor element with a basic shape that corresponds to the combination of a plurality of square basic elements, especially to an angular floor element. The floor element includes projections and recesses along its peripheral sides of the basic element when seen from the centre of the respective top face of the basic element is substantially point-symmetric with respect to its mid-point. The floor element in further embodiments includes a profile that consists of three projections and three recesses.

A continuous covered area, such as a sidewalk or patio, is formed 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.

A method of removing a predetermined area and depth of formable material from an expanse of the formable material having a top surface. The method makes use of a volume indicating tool that includes a depth indicator that has a material surface indicator and a depth guide. The material surface indicator is at a height above the depth guide substantially equal to the predetermined depth. The volume indicating also includes an area indicator, indicating an area equal to the predetermined area. The volume indicating tool is pushed into the formable material until the material surface indicator is level with the top surface of the formable material, thereby pushing the depth guide to the predetermined depth. Then a shovel is pushed into the deformable material until it reaches the depth of the depth guide and is used to gather formable material. The shovel is emptied at a location away from the shovel guide tool. The shoveling process is continued until the area indicated by the area indicator is cleared of formable material down to the depth guide.

A pre-fabricated warped pavement slab and a forming system for making the slabs. The forming system includes a plurality of forming sections which can be adjusted so as to form a warped-plane pavement slab. Also disclosed are methods for making the pavement slab and forming system. Also disclosed is a method for installing the warped pavement slab.

Ground covering element (2) having the basic shape of a square. On all four basic sides (4.1, 4.2, 4.3, 4.4), there is provided one engaging means (8.1, 8.2, 8.3, 8.4) each. Each of the engaging means is symmetric with respect to a central axis of symmetry (12). Opposite engaging means are mirror images of each other. Each engaging means is complementary with the engaging means on the two basic sides adjoining around the corner. On each of the four corner regions of the ground covering element, there is provided a protrusion (24) having substantially the shape of a rectangular, isosceles triangle or of an area element similar to this triangle with curved legs. By omission of the four protrusions (24), a ground covering element of the second type (42) is obtained which may be laid together with additional ground covering elements of the second type (42) or in combination with ground covering elements of the first type (2).
摘要:
A method of manufacturing a covering material for covering a substrate such as ground, a floor, walls or the like, is described wherein the covering material includes a complex visual design. The steps include selecting the design, creating a plurality of adhesive-backed vinyl design sections corresponding to distinct predetermined areas of structure and color of the design and having a predetermined horizontal and vertical orientation and location within the design, marking the design sections to identify the predetermined color, orientation and location, selecting blank elements corresponding in color to the identified colors marked on the design sections, selecting a surface of each blank element to correspond to an upper design surface of a design element, fixing the design sections to the upper design surface of the appropriate corresponding color of blank element, cutting the blank elements to form design elements, wherein the upper design surface of each resulting design element has a plan form shape corresponding to the plan form shape of the affixed design section, preparing background elements having a void sufficient to accommodate the design elements; assembling the design elements into the void in an inter-engaging relationship in accordance with the identified orientations and locations marked on the affixed design sections, and removing the design sections from the design elements.

A concrete block has a first and a second hole passing through the concrete block in a vertically direction. An internal thread is formed in the first and the second hole. A plurality of tiles have a slipping resistivity. The tiles are arranged in order on an upper surface of the concrete block. The first and the second hole each have at a level of the upper surface an open region smaller than a respective tile.
