Abstract

(57) [Summary] [Purpose] A dry method is used to shorten the construction period and reduce the construction cost. [Structure] A sand layer 6 which is a sandstone layer is laminated on a crushed stone layer 1 which is a crushed stone layer. A plurality of paved flooring materials A, which are made into blocks of an appropriate size, are arranged on the sand layer 6. Each pavement floor material A is fixed by making the sand of the sand layer 6 bite into the concave grooves 7 provided in the vertical and horizontal grids on the back surface of each pavement floor material A.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a paving floor material mounting structure used for paving a passage or the like from a road to a front porch, and more particularly to a structure used for mounting a paving floor material by a dry method.

[0002]

[Prior art]

 Conventionally, in the case of paving the passageway from the road to the entrance porch in a house, construction was performed as shown in Fig. 5. That is, the crushed stone layer 1 is formed in the crushed stone ground industry, concrete is poured onto the crushed stone layer 1 to form the concrete layer 2, and after the concrete layer 2 is hardened, the mortar layer 3 is provided on the concrete layer 2. A stone material 4 such as granite is laminated and integrated on the mortar layer 3.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional example, there is a problem that the construction takes a long period of time and the construction cost is required because the construction is carried out by the wet method. The present invention has been made in view of the above problems, and an object of the present invention is to provide a paving floor material mounting structure that can be constructed by a dry method, can shorten the construction period, and can reduce the construction cost. is there.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the mounting structure of the pavement flooring material of the present invention is such that the pavement flooring material A, which is made into a block of appropriate size, is formed by laminating the sandy layer 6 on the crushed stone layer 1 A plurality of pavement floor materials A are arranged on top of each other, and each pavement floor material A is fixed by making the sand of the sand layer 6 bite into the concave grooves 7 provided on the back surface of each pavement floor material A in a grid pattern in the vertical and horizontal directions.

[0005]

[Action]

 According to the above configuration, the pavement flooring material A, which is pre-blocked and formed in the factory, is arranged on the sand layer 6, and the pavement flooring material A is pressed by pressing the pavement flooring material A and causing the sand of the sand layer 6 to bite into the groove 7. Can be fixed so that it does not shift laterally. As a result, the pavement floor material A can be attached and constructed by the dry method, and the construction period can be shortened and the construction cost can be reduced.

[0006]

【Example】

 The paving floor material A is formed in a block into a suitable size in a factory, and a surface finishing stone material 9 is integrally provided on a concrete base material 8. A material such as CFRC (carbon fiber rain hose concrete) is used as the concrete base material 8. The CFRC provides high strength, light weight, durability, dimensional stability, and fire resistance. As the surface finishing stone material 9, natural stone such as granite, artificial stone, tile or the like is used. When the pavement flooring material A 1 is manufactured, concave grooves 7 are formed vertically and horizontally on the back surface of the base material 8 as shown in FIG.

However, the paving work of the passage between the road and the entrance porch is performed as follows using the paving floor material A configured as described above. First, the ground 10 is excavated to a certain depth, and the excavated portion is subjected to crushed stone ground work to form a crushed stone layer 1 as shown in FIG. In the case of the present embodiment, the first crushed stone layer 1a and the second crushed stone layer 1b are formed by performing the crushed stone ground work twice. Next, the sand layer 6 is laminated on the crushed stone layer 1 by performing sand industry. The sand of the sand layer 6 may be mixed with a solidifying agent such as cement. The pavement floor material A is arranged on the sand layer 6 as shown in FIG. 4, the pavement floor material A is pressed from above, the sand of the sand layer 6 bites into the groove 7, and the pavement floor material A is laterally displaced. Fixed so that there is no. At this time, if the paving floor material A ′ located at the end is fixed by an anchor or the like to prevent a plurality of paving floor materials A from shifting laterally, the paving floor material A can be fixed more securely. Further, if the sand layer 6 is mixed with a solidifying agent such as cement, the pavement floor material A is fixed with the solidifying agent, and the fixing is further ensured.

[0008]

[Effect of device]

 The present invention, as described above, stacks a sand layer on a crushed stone layer on a crushed stone layer and arranges a plurality of pavement flooring blocks that are of an appropriate size on the sand layer. Since each pavement floor material is fixed by digging the sand of the sand layer into the grooves formed in a grid pattern in the vertical and horizontal directions on the surface, the pavement floor formed by pre-blocking at the factory after crushing stone and sand It is possible to fix the pavement floor material by arranging the material on the sand layer, pressing the pavement floor material, and making the sand of the sand layer bite into the concave groove on the back surface of the pavement floor material. Installation work can be done, the construction period can be shortened, and the construction cost can be reduced.
