[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a paving block laying method applied when paving roadways, sidewalks or other spaces using paving stones such as natural stones or artificial stones of a predetermined shape, concrete blocks, bricks, and the like. It relates to the paving block used.
[0002]
[Prior art]
Conventionally, for example, as shown in FIG. 10, as shown in FIG. 10, a crushed stone roadbed b is formed on a roadbed a, and a concrete layer c is hit thereon, Further, there is known a laying method in which a paving stone e is laid after laying an empty kneaded mortar d, and finally a joint f is provided between the paving stones.
However, with this method, considerable effort is required to arrange paving stones, adjust the surface height level, adjust the joint spacing, etc., and even those with considerable experience require considerable effort and the laying area per hour is Few.
In addition, when laying, a crushed stone roadbed is formed on the roadbed, or a concrete layer is laid on top of it as a base, and then a dry stone mortar is laid on the base, and then a paving stone is laid. Many laying processes are required, such as applying joints, and there is a problem that laying takes a long time.
[0003]
For this reason, in order to improve the efficiency of laying paving stones, many proposals have been made, such as the devices described in Japanese Utility Model Publication No. 50-89123 and Japanese Utility Model Publication No. 1-124804, and some improvements have been made. However, there is a problem in processing cost.
[0004]
In addition, when laying the paving stones directly on the ground with uneven terrain or slope that is simply leveled and omitting the laying process, it is not easy to align the surface of many paving stones arranged on the ground to a predetermined level. However, there is a problem that it takes a long time to lay because it requires skill and considerable effort.
[0005]
In order to solve such a problem, Japanese Patent Laid-Open No. 6-306809 discloses that a flat block is laid through a level adjusting mechanism, and then mortar is poured into a gap on the lower side of the flat block to be hardened. A paving method using a flat block forming an intermediate layer to be filled has been proposed.
The level adjustment mechanism in this paving method is composed of a receiving piece on which a bolt / nut and a flat plate block are placed, and the level is adjusted by adjusting the bolt length under the nut by rotating the bolt or nut in advance. Therefore, it is difficult to perform minute height adjustment and quick level adjustment.
[0006]
Further, Japanese Utility Model Laid-Open No. 7-12501 discloses a natural stone paving stone in which a slip stopper is fixed to the back surface of the paving stone and a spacer is projected on the side surface to form a joint interval. However, even when laying this paving stone, it takes time and effort to adjust the surface height level.
[0007]
[Problems to be solved by the invention]
The present invention can easily and reliably adjust and maintain the gap between the upper surface of the base and the back surface of the paving block when paving stones, concrete blocks, etc. (hereinafter referred to as “blocks”) having a predetermined shape are used as the paving block. A method for laying a paving block, which can easily obtain the flatness of the surface of the paving block even if it is not a person, and can reduce the laying cost by shortening the laying process and laying time, and is used for carrying out this laying method.

DETAILED DESCRIPTION OF THE INVENTION
In the present invention, a number of paving blocks engaged with a surface level adjusting member made of an elastic material are arranged on a leveled base, and the surface level of the many paving blocks is previously incorporated in the paving block. And adjusting the gap between the paving blocks to a predetermined joint spacing by using joint joint spacers provided in advance in the pavement block, and forming joints. The gap between the lower surfaces is filled with a filler and solidified, and the pavement blocks can be easily constructed by integrating the pavement blocks and between the base and the pavement block.
[0013]
That is, the pavement blocks are arranged while maintaining the joint interval between adjacent pavement blocks by joint spacers for forming predetermined joint intervals previously incorporated in the pavement block on the base, and then incorporated in the pavement block in advance. By pressing and adjusting the level adjusting member, the height of the upper surface of the pavement block can be adjusted easily and reliably.
[0014]
After that, the pavement block is securely fixed on the base by filling the gap between the upper surface of the base and the lower surface of the pavement block and the gap formed between the adjacent pavement blocks by filling with a filler from the joint gap. A pavement can be constructed with paving blocks.
At this time, since the level adjusting member is pressure-bonded to the base, it also serves to prevent slipping so that the paving block does not move during construction.
Further, although the pavement block itself has a considerable weight, according to the laying method of the present invention, it is possible to lay the pavement block very easily regardless of the level of proficiency of the pavement block installation technique of the worker. Compared with the method of laying with a flowing mortar, it is only necessary to fill the filler from the joint gap, so that the laying process can be simplified and the laying time can be shortened, and the laying cost can be reduced.

If there is, it is also effective to apply a viscous material or an adhesive material (including the combination with unevenness) to increase the frictional resistance.
Further, by forming an appropriate uneven level adjusting member in contact with the base, it is also effective to provide a displacement preventing effect of the basement top.
[0016]
Here, for example, concrete pavement or asphalt pavement is optimal as a base for constructing a pavement by a pavement block, but it may be any asphalt stabilization processing roadbed or crushed stone roadbed. In addition, it may be a boardwalk, a cycling road, an entrance of a plaza or a building of a park, etc., and also a foundation formed by a conventional paving stone laying method as well as a dirt floor or a concrete floor of a building. .
[0017]
The filler used in the present invention is filled by pouring, has fluidity at the time of filling, has a good filling workability, and solidifies after filling to give strength and bonding properties. What you have is good.
As the kind of filler, for example, cement milk and cement mortar are suitable. However, the filler is not limited thereto, and may be selected from any one of cement paste, epoxy resin, polyester resin, urethane resin, and a mixture based on these resins.
[0018]
As the material for the concave portion and the spacer, various resin materials that are lightweight and elastic and can be obtained at low cost or those based on resin materials are suitable, but not limited to this, those having the above characteristics If there is no particular limitation.
[0019]
A recess material is previously fitted in the fitting hole on the back surface of the pavement block, and a level adjusting member that can be manually pushed is engaged with the recess material. Moreover, the level adjustment by pushing the level adjusting member after laying can be performed by driving with a mallet on the surface of the pavement block, or by rolling the leveling roller.
The number and arrangement of level adjustment members are determined according to the shape of the pavement block, but the level adjustment member stabilizes the support of the pavement block to adjust the level, the gap between the base and the joint gap. In order to make sure, in general, it is preferable to form a regular arrangement of 3 to 4, but the number and arrangement are not limited to this as long as the object can be achieved.
[0020]
As described above, in the present invention, various types of paving blocks are laid, but it is particularly difficult to process and is suitable for a heavy natural stone paving stone.
