Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention can be easily constructed on roads, plazas, parking lots, sidewalks, etc., and also makes it possible to obtain solid pavements and roadbeds. This is related to the laying blocks.

[Conventional technology]

BACKGROUND ART Conventionally, various materials have been used for pavements such as roads and plazas.

For example, the entire road surface may be paved with asphalt or concrete, or a large number of single blocks, tiles, etc. may be connected to the roadbed in a planar manner via sand, and each connecting surface may be covered with a joint material such as mortar. It was connected with.

[Problem that the invention seeks to solve]

The above-mentioned conventional technology has a problem in that the construction work requires a considerable period of time when the entire surface is paved with asphalt or concrete.

In addition, when installing single-piece blocks, tiles, etc., cracks may occur due to joint breaks, etc., and blocks may shift laterally or level differences, resulting in safety problems when walking or driving a vehicle. There was a point.

The present invention has been made to solve the above problems,
The purpose of this is to provide a connecting groove in the center of the block body, form a protrusion in the corner of the block body, and lay this block body in two layers, an upper layer and a lower layer, one on top of the other.
To provide a laying block that is easy to construct and makes it possible to obtain a solid pavement.

c. Means for Solving the Problem] The present invention provides a means for solving the above-mentioned problem, in which a circular, square, etc. A connection groove is provided, and protrusions each having a shape obtained by dividing the connection groove into four equal parts are formed at the corners of the block body.

[For production]

Since the present invention is constructed as described above, the construction state thereof will be explained. First, the flat surface of the block body is placed downward on the roadbed, and the side surfaces of the block bodies are brought into contact with each other to form a lower laying surface. The protrusions formed at the corners of the main bodies are formed in the same shape as the connecting grooves, and the connecting grooves of the respective block bodies are arranged in a concave state. Then, next, the block bodies are stacked one after another in close contact with the laid block surface, with the flat surface facing upward. That is, the protrusions formed upward at the corners of the block bodies described above are fitted into the connection grooves provided in the center of the block bodies, and the protrusions formed at the corners of the block bodies are brought into the concave state. It fits into the connecting groove. Thereafter, the upper block bodies are laid one after another in this manner, and the protrusions formed by the corners of the upper block bodies are fitted into the connection grooves of the lower block bodies, and vice versa. A protrusion formed at a corner of the lower block body is fitted into the connection groove of the body.

That is, the upper block main body and the lower block main body are stacked in two stages, stacked one on top of the other, and are brought into close contact with each other alternately, and are connected in a planar manner without a joint material to form a flat laying surface.

As a result, it is possible to prevent the block body from shifting laterally or from forming a step, and it is possible to obtain a solid laid block.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

In Figures 1 and 4, 1 is a block body formed by integral molding of concrete, and is formed into a square shape, the front side 2 has a flat surface, and the back side 3 has a circular connecting groove in the center. 4 are provided in a tapered shape, and protrusions 5 are formed at the four corners of the block body 1 on the back surface 3 side, and these protrusions 5 divide the circular connecting groove 4 into four equal parts. Form into shape. That is, in this embodiment, the protrusions 5 are formed in a fan shape, and when the block bodies 1 are laid in close contact with each other as shown in FIG. 4, each protrusion 5 is formed in a disk shape. It is configured to have a shape that can be fitted into the connection groove 4.

A construction example according to this embodiment will be specifically explained below.

In Figure 5, 6 is a subgrade of sand 7 after the ground has been leveled in advance with the subgrade.
Then, as shown in FIG. 6, the block body 1 is laid on the litter 7 with the surface 2 of the block body 1 facing down and the block body 1 being fairly close to each other. In this case,
On the back side 3 side of the block body 1 formed in a square shape,
The connecting grooves 4 provided in the center of each block body 1 are concave and located at equal intervals, and the protrusions 5 formed at the four corners of the block body 1 form a set of four to form a disc shape. is formed upwards. As explained in the above configuration, the protrusions 5 are formed by dividing the connection groove 4 into four equal parts, so that the four protrusions 5 formed in the shape of a disk are in close contact with each other.
has the same shape as the connecting groove 4.

In this way, after the block bodies 1 are laid down in a suitable area so as to be in close contact with the lower tier, the block bodies 1 in the upper tier are stacked. That is, the lower disc-shaped protrusion 5 is fitted into the connection groove 4 of the upper block main body 1, and the upper protrusion 5 is fitted into the lower connection groove 4. As the upper block bodies l are sequentially laid in this way, the upper protrusions 5 are fitted into the lower connection grooves 4, and the lower protrusions 5 are fitted into the upper connection grooves 4, respectively. At the same time, the back parts 3 also come into close contact with each other, and the respective block bodies 1 are laid flat.

In other words, the upper block body 1 and the lower block body 1
and are alternately brought into close contact with each other and are connected in a flat manner.

As described above, in this embodiment, the square block bodies 1 are laid in the upper and lower tiers, and are placed in close contact with each other alternately.
Because the protrusion 5 is fitted to
Lateral displacement of the block body 1 also does not occur.

Although concrete is used as the material for the block body 1 in this embodiment, it is not limited to this, and other materials such as metal, ceramics, wood, etc. may also be used.

7 and 8 show other embodiments of the present invention,
FIG. 7 shows that the connecting groove 4 of the block body 1 is provided in a diamond shape,
The protrusion 5 is formed in a triangular shape, and in FIG. This embodiment also has the same functions and effects as the embodiments described in FIGS. 1 to 6.

〔Effect of the invention〕

As explained above, the present invention provides a block body with a connecting groove and a protrusion, and lays this block body on an upper stage and a lower stage,
Since the two are stacked alternately and the connecting grooves and protrusions are fitted and connected, there is no difference in level on the pavement surface or lateral displacement of the block body, and it is possible to obtain a solid block to be laid without the need for joint material. becomes.

Further, in the present invention, since block bodies formed as single units are simply laid in parallel, the construction work can be easily carried out, and there is no need for joint materials or the like.

Furthermore, the present invention has various effects such as being able to be used not only for roads but also as an intermediate member for paving plazas, parking lots, etc., and as an intermediate member for roadbeds and ground.
