Abstract

PROBLEM TO BE SOLVED: To provide a paving method by which the width of a gap of pavement blocks can be easily regulated, without requiring correction after being laid, and working efficiency can be remarkably improved, when many pavement blocks are arranged on a sand cushion layer laid on the roadbed so as to be spaced by a fixed gap. SOLUTION: When many pavement blocks 11 are laid on a sand cushion layer laid on the roadbed so as to be spaced by desired gaps, a block frame 10 which is formed into a plate of smaller thickness than the pavement block 11, and provided with many guides 10a capable of being inserted with the pavement blocks 11 spacedly by the above-stated gap, is placed on the sand cushion layer, and the pavement blocks 11 are inserted into the guides 10a so as to be laid on the sand cushion layer. Thereafter the gaps between the adjoining pavement blocks 11 are filled with soil or gravel so as to cover the block frame 10.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is for laying a large number of paving blocks made of concrete, bricks or the like on open roads, parks or open spaces around buildings with a gap between each paving block. Pavement method.

[0002]

2. Description of the Related Art As a method of paving in which lawn is mixed between paved surfaces, a roadbed and a sand cushion layer are provided in order on the roadbed, and the sand cushion layer is preliminarily provided on the sand cushion layer.
Laying a large number of paving blocks with one or two vertical holes penetrating through them at close intervals so that a narrow gap of a few millimeters in width is created between adjacent paving blocks. There is known a method of filling the vertical holes with soil and planting grass on the soil surface.

[0003]

However, the method of densely laying the paving blocks with vertical holes is limited to the area of the vertical holes provided in the block on the lawn surface, and the blocks collide with each other to form a corner. Had a problem that it was easily damaged. Therefore, it was attempted to lay pavement blocks at wide intervals, fill the spaces with soil and plant grass.
Since a large number of paving blocks are arranged on the surface of the sand cushion layer where there is no mark, it is difficult to make the gaps between the blocks uniform, and the above gaps may vary and the block rows may be distorted. There was a problem, and there was a problem that it took a long time to lay it. In addition, it is not practical to stretch the water threads in the vertical and horizontal directions if the number of water threads is one or two, and if the number of water threads is increased, there is no foothold.

According to the present invention, when a large number of paving blocks are arranged on a sand cushion layer laid on a roadbed with a predetermined gap, the widths of the gaps can be easily made uniform. It is intended to provide a paving method capable of significantly improving work efficiency without the need for modification.

[0005]

The pavement method according to the present invention comprises:
When laying a large number of paving blocks on the sand cushion layer laid on the roadbed with a desired gap, form a plate shape with a thickness smaller than that of the paving blocks on the sand cushion layer. And put a block frame with a large number of guides that can insert the paving block with the gap above, insert the paving block into the guide and lay it on the sand cushion layer, After that, the space between adjacent pavement blocks is filled with soil or gravel to fill the block frame.

The pavement block may be of any material and shape. The material is a normal aggregate concrete block, a reinforcing bar block formed by pouring fresh concrete, a surface layer portion and a base layer portion. Part with colored mortar layer, base layer part with concrete layer,
Examples of water-permeable concrete blocks using coarse aggregate, brick products, etc., as the shape, the planar shape is square,
Rectangular, circular, trapezoidal, hexagonal, octagonal, those with one or two vertical holes penetrating in the outer shape, those with a jagged pattern on the periphery, joints on the periphery An example is one in which a plurality of protrusions having a height of about 1 to 3 mm are provided to project.

The block frame used in the present invention is a perforated plate or lattice having a large number of guides into which paving blocks can be inserted in the form of holes or grooves, and is preferably made of plastic. When a plastic that is not decomposed by microorganisms or water is used as a plastic, the pavement block will not be displaced after laying, but biodegradable polymers that have the property of being decomposed by microorganisms or water in soil, such as fatty acids. When polyester, polyglycolic acid, polylactic acid, or the like is used, the block frame naturally decomposes and disappears within a few months after the paving block is laid. The shape of the block frame may be a strip long in one direction, and the guides in the shape of a large number of holes or grooves may be arranged in a single row. The guides may be provided in a grid pattern or a honeycomb pattern of rows, or the frame shape may be circular or semicircular, and a large number of guides may be arranged radially or concentrically.

The shape of the guide provided on the block frame is
As long as the paving block to be used has a shape that allows the paving block to be smoothly inserted, it does not have to be the same as or similar to the planar shape of the block, and is circumscribed to the paving block. Circles, squares and other shapes can be selected. Also, 2 of the paving block
It is also possible to open a hole having a size equal to or more than twice and insert one paving block biased to one side of the hole and insert another paving block biased to the opposite side. Further, by forming a protrusion on the inner surface of the crosspiece and by separating the two paving blocks at a predetermined interval by the protrusion, a guide capable of inserting three or more paving blocks into one hole is formed. You can In particular, at the edge of the block frame, if the paving block can be positioned, it is possible to use a groove-shaped guide instead of the hole shape.

The vertical and horizontal or diagonal arrangement pitch of the guides is set according to the arrangement pitch of the paving blocks. The crosspieces and ridges that separate the guides may be hollow, and the cross-sectional shape can be formed in any shape such as U-shape, T-shape, I-shape, and many small holes are formed in the crosspieces. It can be densely formed to have a porous or reticulated structure, and the weight can be reduced within a range in which it is not stretched or deformed by a slight external force.

The block frame preferably has a side length of about 1 to 2 m from the viewpoint of workability during transportation and block arrangement. The thickness is preferably 1/2 or less of the height of the pavement block, and when the thickness exceeds 1/2 of the height of the pavement block, when filling the space between the pavement blocks with soil or the like, the block frame The soil layer above the cross section becomes thin, and this soil layer is easily peeled off.

The above-mentioned block frames are arranged on a sand cushion layer on a roadbed prepared in advance in a predetermined area such as a road, a garden, or a plaza to be paved with a paving block, and then used for each guide of the block frame. Pavement blocks are inserted as appropriate. Then, when the laying by inserting the paving blocks is completed, the space between the paving blocks is filled with soil or gravel, and grass is planted on the surface of the soil as needed. When the paving block has vertical holes, the vertical holes are also filled with soil or gravel, and grass is planted on the surface of the soil as needed.
