Definitions

  • This invention relates to paving blocks for use as paving instead of the traditional concrete or reconstituted stone slab or tarmacadam surface.
  • Paving blocks are known which when in use have vertical sides.
  • the blocks may be rectangular in shape or provided with a sideways interlocking shape.
  • Such blocks are generally laid on a sand base below which is a further more solid base and it is usual to pack the small gaps between adjacent blocks with sand.
  • the blocks so laid are located against lateral movement but individual blocks derive no support from adjacent blocks in resisting vertical loads. The foundation for the blocks must therefore be of sufficient strength to resist the vertical loading.
  • each block has recesses which extend upwardly from the base of the block while the other sides of the block have recesfes extending downwardly from the top of the block.
  • the blocks can therefore be interlocked and loading applied to one block will be shared as described.
  • Another form of block has a pair of opposite sides sloping downwardly and outwardly while the remaining sides slope downwardly and inwardly. Again the blocks form a vertically interlocked structure.
  • a mould for producing such a block needs to have sidewalls which can be retracted from the compacted block to enable the block to be ejected from the mould.
  • Such a mould is expensive to produce and also has limited block making capacity in the sense that only a comparatively small number of blocks can be made at the same time.
  • the block now to be described can be manufactured using conventional block forming techniques which means it can be manufactured cheaply and yet it can still provide vertical interlocking.
  • a paving block comprises a body defining a pair of opposed rectangular surfaces one of which in use will be the upper surface and the other of which will be the base surface, said surfaces being substantially parallel to each other, one of the sides of the block extending at right angles between the surfaces, the side opposite said one side being recessed below one of the surfaces and the two other opposite sides being recessed below the other of said surface.
  • the block has an upper surface 10 and a spaced base surface 11 substantially parallel to the upper surface, and also sides 12, 13, 14 and 15.
  • the upper surface 10 is of rectangular form and the side 14 is vertical and extends to the base surface 11.
  • the sides 12 and 13 extend vertically downwardly from the upper surface for a short distance and then they extend downwardly and inwardly and finally before reaching the base surface, they extend vertically downwardly.
  • the side 15 on the other hand extends downwardly from the upper surface and then downwardly and outwardly. As with the sides 12 and 13 the side 15 extends vertically downwardly before reaching the base surface As a result the sides 12 and 13 are recessed immediately below the base surface 11 and the side 15 is recessed immediately below the upper surface 10.
  • the blocks have a different length/width ratios and in fact are four times longer than they are wide. They can be assembled together as shown to leave gaps 24 which can be filled with soil or other plant growing compound, to allow plants or grass to be grown. As with the previous arrangement, vertical load applied to one block will be in part distributed to two other blocks. It will be understood that other length/width ratios can be employed. In the use of a block as described to construct a paved area, it is always associated with a similar block the two blocks being located in back to back relationship that is with their sides 14 in facial contact.
  • FIG. 4 and 5 is similar to the block shown in Figure 1 except that the sides 12A, 13A and ISA are curved instead of having plane portions, the curvature of the sides 12A and 13A being opposite to that of the curvature of the side 15A. Again the side 14A of the block is vertical.
  • Figure 5 shows how the sides of two of the blocks of Figure 4 fit together although in practice there will be a small gap which as stated will be filled with sand.
  • Figure 6 shows part of a mould for producing the block shown in Figure I.
  • the mould box 25 defines a series of compartments in side-by-side and in end-to-end relationship and in each compartment a block of the type shown in Figure 1 can be formed.
  • the box includes a plurality of lateral plates 26 which extend in spaced parallel relationship and which form the top and bottom surfaces of the blocks.
  • the plates 26 are interconnected by cross plates 27 which form the shaped opposite sides 12 and 13 of the blocks.
  • the cross plates have a shape corresponding to the shape of the sides of the blocks.
  • the block produced in one compartment between one pair of plates 26 is the opposite way round to the blocks produced in the adjacent compartments defined between the same two plates. If desired however the blocks can be produced in the mould in the same way round.
  • the mould box in use stands on a base board 28 and a tamper head assembly is provided which can be lowered into the mould box to achieve compaction of the semi-dry mix of material from which the blocks are formed.
  • Each compartment in the mould box has its own tamper plate 29 which forms part of the tamper head assembly.
  • the under surface of the tamper plate is shaped to produce the side 15 of the block.
  • the mould box is lowered onto the base board and with the tamper head assembly lifted clear, moulding material is placed in the compartments formed by the mould box and base board.
  • the loading of the material can be achieved in any desired manner for example, a feed box can be moved laterally over the mould box.
  • the tamper head assembly is lowered and the individual tamper plates enter their respective compartments.
  • Compaction may be achieved with the assistance of vibration and when it is deemed that the compaction is sufficient, the vibration is stopped and the mould box is lifted vertically away from the base board while the tamper head assembly is held against movement.
  • the practical effect of this is that the compacted blocks are ejected from the mould box and remain upon the base board.
