Description

[Detailed description of the invention] This invention relates to a concrete pavement body that has multifaceted effects such as being able to extend the life of the pavement.

As is well known, pavements such as roads are made of various materials, and among these, the pavement plates used for cement-based pavements and the paving stones used for paving sidewalks are made using this method. In this case, there are various advantages compared to a method in which a paving body made of other materials or a paving material is directly placed on the roadbed.

In other words, due to the characteristics of cement, it is impossible to completely eliminate the occurrence of cracks in cement-based pavements after hardening.
When paving slabs and paving stones are laid on the roadbed, joints are created to concentrate the cracks in specific locations, but in reality, this is not the case. The occurrence of cracks could not be completely eliminated by using joints alone, and many cracks were observed, and repairing especially heavy items such as paving slabs was very time-consuming and difficult.

In addition, in the case of paving stones, they are simply laid on the roadbed, and the paving stones are not connected to each other, so if the roadbed surface is uneven and uneven, it may occur within a short period of time after construction. There is a problem in that the paving stones create a step difference between each other, making walking extremely dangerous.

In addition, another conventional technology has developed a road reinforcement material having a structure in which steel members having a U-shaped cross section are bent in contrast to each other and are fixed to each other with bolts to form a continuous hexagonal frame. The tortoise shell frame is used with or without cement or other road construction materials filled, but the lower or upper edges of steel members with a U-shaped cross section are cut out and these steel members are tightened with bolts. As a result, the manufacturing process was complicated, and there were various drawbacks, such as the lack of measures to prevent rainwater from entering.

Therefore, this invention aims to provide a pavement body that can solve the above-mentioned problems with a very simple structure.

An embodiment of this invention will be described below based on the drawings.
Reference numeral 1 denotes a partition frame aggregation board set to a predetermined size, in which a large number of hexagonal partition frames 2 are connected vertically and horizontally in a planar manner. On the periphery, as shown in Fig. 2, a stabilizing plate 2b having a rainwater stopper strip 2a on the tip periphery is integrally molded, and concrete 3 is filled so that the top surface coincides with the inside of each compartment frame 2. It is structured as follows.

In order to pave a road using the paving body of this embodiment, first of all, if the levelness of the roadbed is poor as shown in Fig. 2,
Then, after installing the partition frame gathering board 1 in the predetermined position one after another before filling with concrete 3, flatten the inside of each partition frame 2 with the top surfaces aligned as described above. Fill with concrete 3 and compact it,
Construction is completed when the concrete 3 hardens naturally.

As described above, this pavement body is constructed by integrally molding a plurality of partition frames 2 of the same shape (example) or a different shape with synthetic resin and connecting them in a plane. For example, since we have a structure in which concrete 3 is filled with the upper surface of Of course, it is easier to pave than the paving method that involves pouring paving materials onto the roadbed, similar to paving stones. Because it is stored and held inside, cracks are less likely to occur, preventing damage and making it extremely robust.
It has the advantage of increasing pavement life.

Furthermore, in the concrete pavement body according to this invention, the paving blocks (concrete 3) are housed and held within the partition frame 2, and are connected to each other by the partition frame assembly board 1 and installed on the subgrade. In addition, when this is installed on a flat, compacted roadbed, it can be installed stably without causing sideways shifts or steps like conventional paving stones, increasing safety when walking and running. In addition, by appropriately coloring the partition frame collecting board 1 and the concrete filled in the voids of this partition frame collecting board 1, the aesthetic appearance of the road surface can be enhanced.
Alternatively, it has the advantage of being able to be used as a road sign.

Furthermore, since a stabilizing plate 2b and a rainwater stop strip 2a are provided on each compartment frame 2 of the compartment frame aggregation board 1, the paving block (concrete 3) formed by the division frame aggregation board 1 and concrete when installed on a subgrade. The stability of the concrete is very good, and since the rainwater that enters between the partition frame 2 and the concrete 3 caused by the drying shrinkage of the concrete does not enter the subgrade, the slack of the subgrade is suppressed as much as possible. By appropriately selecting and combining the size of the partition frame 2 and the material of the partition frame assembly board 1 and concrete, you can freely create roads, sidewalks, parks, parking lots, station premises, platforms, etc. It can be made into a pavement suitable for paving entrances, dirt floors, etc., and is of extremely high value as a practical pavement structure.

3 to 6 show different embodiments of this invention, and the one in FIG. 3 has an r-shaped cross section with a non-slip pattern 4a formed on the top surface of the embodiment shown in FIGS. 1 and 2. After filling the compartment frame 2 with the rubber non-slip material 4 and the concrete 3, the non-slip pattern 4a is made to slightly protrude from the top surface of the compartment frame 2 as shown in the figure before the concrete 3 hardens. Further, it is inserted so that its back surface is in contact with the peripheral wall of the partition frame 2, and is firmly fixed and attached as the concrete 3 hardens.

Moreover, what is shown in FIGS. 4 to 6 respectively shows modified examples of the shape of each compartment frame constituting the compartment frame aggregation board, and each of the examples shown in FIGS. It goes without saying that the same efficacy as that of the example can be expected.

It should be noted that the pavement body of this invention is not limited to the structure of the embodiments, and may of course be subject to various design changes as long as they do not deviate from the technical idea stated in the claims of the utility model registration.
