Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to an improvement of ceramic blocks for road pavement.

[Conventional technology]

Conventionally, ordinary concrete blocks or ceramic tiles have generally been used for pavement of sidewalks and roads.

[Problem that the invention attempts to solve]

Concrete blocks are easy to construct because all you have to do is spread sand on the roadbed and lay them in rows on top of it, but
The disadvantage is that the surface appearance is always uniform and does not change much, and it is easily worn out. Concrete blocks also have the disadvantage that, during storage, the surface gets dark, which is characteristic of concrete, which spoils its appearance. In this respect, ceramic tiles have the advantage of looking better and not wearing out as much as concrete blocks, but they have the disadvantage of being more expensive to construct and not being water absorbent. Therefore, the present invention aims to eliminate these drawbacks of concrete blocks and ceramic tiles and provide a block that is both good-looking and has excellent workability.

[Means to solve the problem]

The construction of the ceramic block for road pavement according to the present invention is as follows. A ceramic block surface plate 2 has a stepped portion 3 formed on its lower surface that fits into a recess 4 formed on the upper surface of the concrete block main body 1, and an adhesive 5 is interposed between them. It is fixed by pasting. The ratio of the short side to the long side is 1:2, and the side wall surface on the short side is formed into a single wave shape with one continuous concave part and one convex part, and the long side is The side wall surface is formed into a multi-corrugated shape consisting of two consecutive concave portions and two convex portions alternately. A chamfered portion 7 is formed on the upper edge of the outer periphery of the block surface plate 2.
is formed. Further, on the side wall surface on the short side and the side wall surface on the long side, there are vertical grooves 6 whose upper ends are continuous with the chamfered portion.
has been established.

[Effect]

By interlocking the double waveforms on the long side wall surfaces of adjacent blocks, the single waveforms on the short side sidewall surfaces, or the double waveforms and single waveforms, the adjacent blocks are brought into close contact with each other. It is possible to easily construct a firm pavement in which they cannot be displaced or moved carelessly. Grooves formed by the chamfered portions of the upper edges of the outer peripheries of adjacent block surface plates are formed continuously in the vertical and horizontal directions to receive and drain rainwater, or allow the received rainwater to seep into the ground from the joints of the adjacent side walls. can. Rainwater or the like that enters the above-mentioned grooves due to the chamfered portions quickly flows down to the ground through the vertical grooves that are continuous with the chamfered portions. In addition, the ceramic block surface plate has a stepped portion formed on its lower surface that is fitted into a recess formed on the upper surface of the concrete block main body, and is pasted with an adhesive 5 interposed between them. Since it is fixed, it will not shift laterally or peel off during use.

【Example】

Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. 1 is mainly made of concrete blocks. This block main body 1 has a short side to long side ratio of 1:
2 is a rectangular body, and the side wall surface on the short side is formed into a single wave shape with one continuous concave part and one convex part, and the side wall surface on the long side is formed with a concave part and a convex part. It is molded into a compound waveform consisting of two consecutive alternating waves. Furthermore, a recess 4 is formed on the upper surface. 2 is a block surface plate made of ceramic. This block surface plate 2 is made of the block main body 1.
As in the case of , it is a rectangular plate with a ratio of short side to long side of 1:2, and the side wall surface on the short side has a single wave shape with one continuous concave part and one convex part. Furthermore, the side wall surface on the long side is formed into a multi-wave shape consisting of alternating concave portions and convex portions and two consecutive convex portions. Furthermore, on the bottom surface, there is a block main body 1.
A stepped portion 3 that fits into the recessed portion 4 is projected, and recessed portions 3a and convex portions 3b are alternately provided on the lower surface of the stepped portion 3 along the longitudinal direction. Reference numeral 7 denotes a chamfered portion provided by diagonally cutting the upper edge of the outer periphery of the block surface plate 2. Block surface plate 2 and block main body 1 having the above structure
are superimposed and fixed in such a state that their short sides and long sides match each other, and therefore their single waveforms and double waveforms match each other. More specifically, the block surface plate 2 has a stepped portion 3 formed into a recessed portion 4.
The block main body 1 is overlaid on the upper surface of the block main body 1 by being fitted into the block body 1, and is adhered and fixed by interposing an adhesive 5 between them. 6 is a longitudinal groove. There are two longitudinal grooves 6 in total, one on the slope of the single waveform on the side wall surface on the short side, and one on the slope of each waveform forming the double waveform on the side wall surface on the long side. The upper end of the book is continuous with the chamfered portion 7. The blocks of the present invention pave the desired road surface by, for example, placing them next to each other on a sand layer b spread on a roadbed a. Double waveforms on the side wall surfaces, single waveforms on the short side wall surfaces, or the double waveforms and the single waveforms are interlocked to bring adjacent blocks into close contact with each other. As a result, between the adjacent blocks, grooves having a V-shaped cross section are continuously formed vertically and horizontally by the chamfered portion 7 on the upper edge of the outer periphery of the block surface plate 2, and the vertical grooves 6 are formed in the grooves. The top edge is continuous. By providing arc-shaped vertical grooves 6 at predetermined positions on each side of the block as in this embodiment, adjacent grooves can be aligned to form elliptical grooves, making water drainage more effective. It is preferable to do so. (See Figures 2 and 3).

[Effect of the idea]

As is clear from the above description, the ceramic block for road pavement according to the present invention provides the following effects. By interlocking the double waveforms on the long side wall surfaces of adjacent blocks, the single waveforms on the short side sidewall surfaces, or the double waveforms and single waveforms, the adjacent blocks are brought into close contact with each other. It is possible to easily construct a firm pavement in which they cannot be displaced or moved carelessly. Moreover, the ratio of the short side to the long side is 1:2, and
The side wall surface on the short side has a single waveform with one continuous concave part and one convex part, and the side wall surface on the long side has a double wave form with two consecutive concave parts and two consecutive convex parts. Therefore, in addition to joining blocks by interlocking their short sides or long sides together, it is also possible to join the short sides of two blocks by interlocking them with the long side of one block. It can bring out the strangeness of the arrangement pattern. Grooves formed by the chamfered portions of the upper edges of the outer peripheries of adjacent block surface plates are formed continuously in the vertical and horizontal directions to receive and drain rainwater, or allow the received rainwater to seep into the ground from the joints of the adjacent side walls. can. Vertical grooves are provided on the side walls on the short side and the side wall on the long side, so that the upper ends of the grooves are continuous with the chamfered portions, so that rainwater, etc. that enters the grooves formed by the chamfered portions does not reach the ground. Flowing down occurs quickly through the longitudinal grooves. In addition, the block surface plate is fixed by fitting the stepped portion on the lower surface into the recess and overlapping the upper surface of the main body of the block, and by interposing an adhesive between them. It is completely integrated and will not shift laterally or peel off during use.
