There is known a laying method in which a concrete layer c is placed on a slab, an empty kneading mortar d is further laid, a paving stone e is laid, and joints f are finally applied between the paving stones and solidified. However, this method requires considerable effort to arrange the paving stones, adjust the surface height level, adjust the joint spacing, etc., and even those who have considerable experience require considerable labor and the laying area per hour is Few. In addition, when laying, crushed stone bed is formed on the roadbed, or a concrete layer is struck on it as a base, furthermore, laying mortar on the base, laying the paving stones, and finally between these paving stones Apply joints, etc.
Many processes are required, and there is a problem that laying takes a long time.

[0003] For this reason, in order to improve the installation efficiency, for example, Japanese Utility Model Laid-Open No. 50-89123 and Japanese Utility Model Laid-Open No. 1-124.
Many proposals have been made, such as the device described in Japanese Patent Publication No. 804, and although some improvements have been made, there is a problem in processing cost. In addition, there is a laying method in which a paving stone is directly laid on a base on which irregularities or slopes have been simply leveled to form a predetermined joint gap, and the joint gap is filled with a filler and solidified. When performing the laying method, it is not easy to form a predetermined joint gap between a large number of paving stones arranged on a base, and there is a problem that it takes a long time to lay because it requires skill and considerable labor. To solve such a problem, Japanese Utility Model Laid-Open No.
No. 01 discloses a natural stone paving stone in which one or a plurality of spacers are protruded from the side surface of a paving stone so that a predetermined joint gap can be formed between the paving stones simply by arranging the paving stones.

However, when the spacer of the natural stone paving stone disclosed herein has one or two small protrusions on one side surface, the joint has a large space area and requires resin or the like to shorten the construction period. When squirting and filling, there is a problem that the amount of the filler used increases, leading to an increase in cost.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of arranging a large number of these pavement blocks composed of concrete blocks, bricks, and hard-to-machine natural stone paving stones, and having spacers on at least one side, on a base. A predetermined joint gap is formed between the blocks by a spacer, and the joint gap and the gap between the base and the lower surface of the pavement block are filled with a filler and solidified to integrate the pavement blocks and the base with the pavement block. This is a pavement block having a configuration in which joint spaces are formed stably and the amount of filler used to fill the joint spaces is reduced.

Hereinafter, the present invention will be described in detail with reference to the embodiments shown in FIGS. As shown in FIG. 1, a pavement block 1 according to a first aspect of the present invention has plate-like spacers 2f and 2s protruding from two adjacent side surfaces of a pavement block main body 1o formed in a predetermined shape. In the case of natural stone paving stones, since it is difficult to form the spacer by integral molding, the spacer is formed, for example, by bonding a plate made of resin with an adhesive or the like.

For example, in the case of a rectangular parallelepiped block as shown in FIG. 1, the plate-shaped spacer is provided on at least a side surface adjacent to the peripheral edge R1 having a predetermined width as an joint.
R4, especially the surface excluding the peripheral edge R1 and the surfaces excluding R2 and R4. In this case, when the peripheral edge R3 is provided, it is preferable that the peripheral edge R1 be mounted so that the width of the peripheral edge R1 is large and the width of the peripheral edge R3 is small. With the interposition of the plate-like spacers, joint spaces are formed at the peripheral edges R1 to R4 between the adjacent pavement blocks, and the joints are filled with filler.

Since the joint spacing is usually 1 to several mm, the thickness of the spacer may be set to a thickness corresponding to the joint spacing to be adopted. In the present invention, particularly, a fluid material such as urethane is used. When resin is used as the joint material, the joint space formed with a narrow width at the periphery of the spacer having a large area, that is, the filling material is filled in the periphery R1 to R4 on the side surface of the cobblestone, so that the laying cost can be significantly reduced. .

However, if the spacer area is too large,
Since the joints between the adjacent pavement blocks are not sufficiently fixed by the joints, the occupied area where the spacers are present on one side of the pavement block is preferably up to about 80%. It is advantageous from the viewpoint of cost that the ratio is set to 40% or more in consideration of the above. For example, as shown in FIG. 1, the area (a ×
b) is 40 of the area A (x × y) of one side of the pavement block.
% To 80%.

When a pavement block is attached, for example, as shown in FIG. 2, on the base kb, the surface of the spacer 2 on the side surface of the opposing pavement block 1a is brought into contact with the side surface of the adjacent pavement block 1b. To form a joint gap B, and the filler 4 is filled in the joint gap B and the gap C between the base kb and the pavement blocks 1a and 1b by the filling device 5 and solidified, and the pavement blocks 1a and 1b and the base kb are formed. The pavement blocks 1a and 1b are integrated. In this case, the joint volume of the filler 4 is reduced by the volume of the spacer 2, and the amount of the filler 4 used can be saved.

This spacer may be formed in a plate shape separately from the pavement block 1 and fixed to the side surface of the pavement block main body 1o by means such as adhesion or engagement, or the pavement block main body 1o is manufactured. At this time, the spacer may be formed directly on the main body, but it is difficult to form the spacer by processing after quarrying like a natural stone. In the example shown in the figure, the spacer is fixed to the pavement block main body 1o by bonding.

When the spacer 2 is formed in a single plate shape, it cannot be said that the space (flow) of the filler 4 into the joint space is always good. Therefore, as shown in FIG. 3, it is preferable to divide the space into a plurality of small spacers 21 and 31 and to form a flow path 6 for the filler 4 penetrating in the vertical direction between the small spacers.

Also, as shown in FIG. 4, the spacer 2 is formed integrally, a plurality of grooves 7 penetrating vertically are formed in the spacer, and a plurality of small spacer surfaces 22 divided by the grooves are formed. May be. The groove 7 serves as a flow passage for the filler 4. In FIG. 3, it is necessary to attach a plurality of small spacers 21 and the positioning and mounting work for each small spacer may be complicated, but in FIG. 4, since the spacers are integrally formed, the positioning and mounting are performed. Work can be simplified.

The small spacers 21 and 3 according to the present invention described above.
1, The front shape of the small spacer surfaces 22 and 32 can be selected from a square, a circle, an ellipse, and any other shape. The front shapes of the flow passages 6 and the grooves 7 of the filler 4 formed between the small spacers and between the small space surfaces differ depending on the shapes of the small spacers 21 and 31 and the spacer surfaces 22 and 32. It is effective, for example, to form the inlet and outlet of the filler 4 on a curved surface so as to make it smooth.

In the present invention, it is also effective to reduce the amount of filler used to fill the joint gaps on the back side of the pavement block 1. For this purpose, as shown in FIGS. It is preferable that a protrusion 8 is provided so as to avoid the peripheral edge 9 on the back surface of the pavement block main body 1o, and a flow passage for the filler 4 is formed in the peripheral edge. In FIG. 6, a leg 11 is provided on the lower surface side of the bottom plate 8, and this leg is attached to the pavement block main body 1o.
The bottom plate 8 is fixed to the pavement block main body 1o by engaging with the engagement hole 10 provided in the above, but may be fixed by bonding.

As shown in FIGS. 8 and 9, an engagement provided on the back surface of the pavement block main body 1o so as not to cause the displacement of the pavement block 1 laid on the base kb on the surface of the bottom plate 8. By engaging the leg 15 of the bottom plate 81 with the non-slip member 13 having the unevenness 12 formed on the surface thereof in the hole 14, the paved block 1 attached to the pavement block main body 1o and laid on the base kb is engaged. Fixing property can be sufficiently secured.

As shown in FIGS. 10 and 11,

Can be secured.

As shown in FIG. 12, a plurality of small bottom plates 8a are attached to the pavement block main body 1o so as to form a flow passage 17 for the filler 4 between the small bottom plates.
As a result, the filler 4 can sufficiently flow around the lower side, and a uniform packing density can be ensured. Here, the small bottom plate 8a can be fixed to the pavement block main body 1o by bonding or by engaging as shown in FIG.

Further, as shown in FIG.
A plurality of small bottom plates 8b, on which the base material 8 is formed, are attached so as to form a flow passage 17 for the filler 4 between the small bottom plates. Further, as shown in FIG.
May be formed so as to form a flow passage 19 for the filler 4 penetrating right and left.

In the case of FIG. 13, it is necessary to mount a plurality of small bottom plates 8b, but in the case of FIG. 14, since the bottom plate 83 is formed integrally, the positioning and mounting work can be simplified. . For fixing the bottom plate 83, any method of bonding or engagement can be adopted. As shown in FIG. 15, irregularities 20 can be formed on the surface of the bottom plate 84.
