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 installation block.

[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 individual 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 techniques have a problem in that the construction work takes a considerable amount of time when the entire surface is paved with asphalt or concrete.

In addition, when single blocks, tiles, etc. are laid, cracks may occur due to broken joints, etc., and the blocks may shift laterally or become uneven, resulting in safety problems when walking or driving a vehicle. There was a point.

The present invention was made to solve the above problems, and its purpose is to provide a connection groove in the center of the block body, form protrusions at the corners of the block body, To provide a laying block which can be laid in two layers, an upper layer and a lower layer, and which can be easily constructed and a firm pavement body can be obtained.

[Means for solving problems]

As a means for solving the above-mentioned problems, the present invention provides a connecting groove in the center of a square block body made of materials such as concrete, metal, ceramics, wood, etc., and connects the corners of the block body. The connecting groove is formed with protrusions each having a shape obtained by dividing the connecting groove into four equal parts.

[Effect]

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 close contact with each other to form a lower laying surface. The protrusions formed at the corners of the block bodies are formed in the same shape as the connecting grooves, and the connecting grooves of the respective block bodies are arranged in concave states. Then, the block main body is placed 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 conversely, the upper block bodies are laid down. A protrusion formed at a corner of the lower block body is fitted into the connection groove of the body.

In other words, the upper block main body and the lower block main body are stacked in two layers and are placed in close contact alternately.
It also connects flatly without any 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 laying 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 part 2 is a flat surface, and the back part 3 has a circular shape in the center. The connection grooves 4 are provided in a tapered shape, and protrusions 5 are formed on the back surface 3 side at the four corners of the block body 1, and these protrusions 5 connect the circular connection grooves 4 in the same shape. Form into equal parts. 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 FIG. 5, after leveling the ground 6 with a roadbed, spread sand 7 to a certain thickness to make it flat, and then as shown in FIG. 6, turn the surface 2 of the block body 1 downward. The block body 1 is laid on the bedding sand 7 so as to be in close contact with each other. In this case, on the back side 3 side of the block body 1 formed in a square shape, the connection grooves 4 provided in the center of each block body 1 are located in a concave state at equal intervals, and the connection grooves 4 of the block body 1 The protrusions 5 formed at the corners are arranged in groups of four and are formed upward in a disc shape. As explained in the above configuration, the protrusions 5 are formed in the shape of the connecting groove 4 divided into four equal parts, so the four protrusions 5 formed in the shape of a disk and in contact with each other are connected. It has the same shape as the groove 4. After the block bodies 1 are laid down in a suitable area in close contact with the lower tier in this manner, the upper block bodies 1 are piled up in weight. 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. When the upper block bodies 1 are laid one after another 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 main body 1 and the lower block main body 1 are brought into close contact alternately and connected in a flat manner.

As described above, in this embodiment, the square block bodies 1 are placed in the upper and lower tiers, and are brought into close contact with each other.
Furthermore, since the protrusion 5 is fitted into the connecting groove 4, no steps are created on the paved surface, and no lateral displacement of the block body 1 occurs.

Although concrete is used as the material for the block body 1 in this embodiment, the material 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. In FIG. 7, the connecting groove 4 of the block body 1 is provided in a diamond shape, and the protrusion 5 is formed in a triangular shape. 8, the connecting groove 4 of the block main body 1 is formed in a square shape, and the protrusion 5 is similarly formed in a quarter square shape, and both embodiments are similar to those in FIGS. 1 to 6. This embodiment has the same functions and effects as the embodiment described above.

〔Effect of the invention〕

As explained above, the present invention provides a block main body with a connecting groove and a protrusion, lays the block main body on an upper stage and a lower stage, overlaps the two alternately, and fits and connects the connecting groove and the protrusion, respectively. Therefore, there are no steps on the paved surface or sideways shifting of the block body, and it is possible to obtain a solid block laid without a joint material.

In addition, since the present invention only involves laying the block bodies formed as single units 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.
