Abstract

To obtain a modular paving block having rough surfaces, a concrete block (10-13) is first provided. Then, the block (10-13) is split in such manner to obtain a modular paving block element (20) having a quadrilateral split rough surface (21). The starting block may be elongate (10), or slab-like (11), or a conventional self-locking concrete block (12,13). The modular paving block elements (20) are laid with their split rough surface (21) facing upwards so as to form a paving. <IMAGE>

Description

  • The present invention refers to a method of obtaining modular blocks for forming paving. This invention further relates to a paving formed by laying such modular blocks.
  • Porphyry cubes paving is well known in the art. Porphyry paving is costly as the material has to be quarried and transported from the quarry to the construction site.
  • From DE-U-9013618 are also known paving block elements obtained by splitting a concrete block. These blocks are used to make paving having a rough surface, similar to the surface of the porphyry cubes. However, these block elements have in many cases two or more adjacent rough faces; therefore, when the elements are laid with one rough face on the top, also many lateral rough faces of adjacent block elements go in contact with each other so that, dust, water and ice can penetrate the blocks, damaging in a short time the paving.
  • A main object of the present invention is to provide modular block elements obtained by splitting concrete blocks so that each block element has either one rough face or two rough faces opposite to each other. Therefore, when laid the blocks with a rough face on the top, only lateral non rough faces would be in contact with each other, so that dust, water and ice cannot penetrate the blocks, and the paving remains in good condition for longer.
  • It is another object of the present invention to construct external paving having an aspect similar to conventional porphyry paving, yet at a considerably lower expense.
  • It is a further object of the present invention to provide blocks in various sizes, colours and thicknesses.
  • A still further object of this invention is to permit to recycle blocks being scrapped as defective or left over from previously produced lots.
  • According to a first aspect of the present invention, there is provided a method as claimed in claim 1. According to a second aspect of the present invention, there is provided a paving according to claim 3.
  • For the understanding of the present invention, reference is made to the following detailed description with the accompanying drawings in which:
    • FIG. 1 schematically illustrates a starting block from which the modular paving blocks of this invention are obtained by splitting;
    • FIG. 2 depicts the conventional laying pattern of blocks forming a porphyry or porphyry-like paving.
  • With reference initially to FIG. 1, numeral 10 designates a concrete block constituting the starting material for obtaining a block in accordance with the present invention. Starting block 10 is quadrilateral in cross section and is elongate in a direction herein defined longitudinal. In this example, starting block 10 is made of a shape which is ideal for slitting easily in two or more elements along one or more transversal breaking planes. Accordingly, each of the block elements 20 obtained by splitting the starting block 10 has at least one rough face 21 formed by splitting. Split face 21 is substantially quadrilateral and has a rough surface which is ideal for constituting the surface of a paving similar to conventional porphyry paving. It has been found that, surprisingly, splitting gives a surface having better anti-sliding characteristics as compared to surfaces obtainable by any other known composition or batching of the concrete forming the blocks. The coefficient of friction obtained by splitting is lasting and is higher than that attained by providing artificial roughness in blocks by means of special moulds. The reason for this seems to lie in that splitting of the concrete block also breaks in two the aggregate granules in the breaking plane without detaching them from the split block portions. The split surface of the stone granules is in turn rough, which contributed in increasing the overall roughness of the split surface.
  • An appreciable aesthetic result can be accomplished by suitably choosing the aggregate composing the starting block 10. The aspect of the split surface can be very similar if not likely to be confused with that of a conventional paving block of natural stone.
  • As shown in FIG. 2, the paving blocks obtained by the method of this invention are well suited for laying according to a conventional circular or arched overlapping pattern of porphyry paving.
  • It will be appreciated that, in accordance with this invention, it is possible to construct porphyry-like paving using blocks having a wide variety of sizes. In addition, the paving blocks of this invention can be produced anywhere, thereby reducing if not eliminating expenses for quarrying the stone (porphyry) and transporting same to the site of application.

Claims (3)

  1. A Method of obtaining a modular paving block element (20), of substantially cubic shape having, at least, one rough face; the method being characterised by comprising the steps of:
    • providing a concrete block (10) of substantially
    • square shape in cross section and elongate shape in the longitudinal direction;
    • splitting said concrete block (10) in such a manner to obtain at least one of said modular paving block element (20) of substantially cubic shape, having no more than two split rough faces (21), these faces being opposite to each other.
  2. A method as set forth in claim 1 characterised in that the modular paving block element (20) has only one rough face (21).
  3. A paving formed by the union of a plurality of the modular block elements (20) obtained according to the method of claim 1 or 2 with their rough faces (21) upwardly directed, to form a paving having the surface rough like a conventional porphyry paving.
