Abstract

PROBLEM TO BE SOLVED: To facilitate laying and construction of paving blocks by placing the paving blocks or the like on plates, and securing their ends by means of angle members. SOLUTION: A roadbed is dug up, and an extruded cement plate 2 is laid thereon, and after sand 3 is further laid thereon, paving blocks 4 are laid. Plates to which angles 5 are attached to prevent movement of the paving blocks 4 are placed at the ends of the paving blocks 4. Since the ground can be flattened by laying a plate such as the extruded cement plate 2, the paving blocks 4 simply need to be laid without requiring technical skill, and since the paving blocks 4 are laid on the plate, settlement does not occur and no pool is formed. Since this pavement structure does not require concrete placing, the period or construction work can be reduced.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pavement structure in which paving blocks are laid on the ground and a construction method.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 6, a pavement structure on which a pavement block or the like is mounted is a roadbed in which a subgrade is dug up and a crushed stone 6 such as split stone is spread on the subgrade of the ground. Is provided, and after solidifying the roadbed with rollers etc., a sand cushion layer made of sand 3 laid on it to a suitable thickness is provided flat, and natural stones and concrete blocks are further placed on it. Paving blocks 4 and so on. In addition, the end where the subgrade was dug up required concrete foundation 7. This is to prevent the end of the paving block from shifting. Moreover,
Excavation of the subgrade is deep, so it is difficult to process the remaining soil. When the subgrade is hard, it takes a long time to excavate the subgrade, which makes the work difficult. In addition, foundation work is difficult in the case of re-placing because the foundation is cast at the end, and two weeks are required for curing concrete, workability is poor, and
It was necessary to take measures to prevent the calcium in the concrete from being eluted and causing the white spots to stain the surface of the paving block. In addition, high technology is required to spread the paving blocks evenly, and even if the roadbed is hardened by rollers or the like, there is a problem that the paving blocks partially sink over time and puddles occur. .

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a pavement structure in which paving blocks are laid in a simple and short period of time and a simple construction method of the pavement structure.

[0004]

Means for Solving the Problems The present invention relates to a pavement structure in which a pavement block or the like is mounted on a plate body, and an end is fixed by an angle member.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION In the pavement structure of the present invention, it is preferable that a pavement block is directly mounted on a plate. The plate material may be a flat plate material such as an extruded cement plate or a veneer plate, and an extruded cement plate is particularly preferred. It is preferable to provide holes in the plate material. In this way, the water flowing from the gap between the pavement blocks can flow underground.

Further, in the pavement structure of the present invention, it is preferable that sand is arranged between the plate and the pavement block as required.

[0007] It is preferable that a separate angle member is fixed to the plate, but it may be integrally formed when the extruded cement plate as the plate is formed. With this angle member, displacement of the pavement block or the like can be prevented.

[0008] The pavement block is preferably provided with a spacer for providing a joint space between the blocks. Further, it is preferable that legs are provided on the pavement block and a gap is provided between the paving block and the plate material. By doing so, water can flow underground through the plate material, so that it is possible to prevent water from accumulating on the pavement surface.
The construction method was such that a plate was laid on a digged roadbed, and blocks or the like were laid directly or on sand. In addition, the end portion is prevented from shifting, such as a block, by mounting an angle instead of the foundation.

For example, any external floor, such as a carport or a terrace, on which a paving block is laid and finished can be used.

Further, in this embodiment, the roadbed is not limited to the ground in the road body structure of the road, but may be anything other than the road body structure as long as the ground is dug and hardened flat.

Further, in this embodiment, the paving blocks include all paving blocks, such as wooden bricks, irrespective of their material and shape, as long as they are paving blocks laid on an external floor.

Hereinafter, the present invention will be described specifically with reference to examples.
