Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paving stone positioning member and a paving stone construction method using the positioning member.

[0002]

2. Description of the Related Art Conventionally, when constructing a road surface, from the viewpoint of matching the road surface with the surrounding environment, etc., a paving stone block having various shapes and colors has been used, and the paving stone blocks are arranged appropriately and mutually. It is known that the road surface is laid in contact to form a road surface having a design property (hereinafter, such a laid state of a paving stone block is referred to as "contact laying").

[0003] Taking a step further, against the background of rising public awareness of the restoration of humanity in recent years, it is not only necessary to form a road surface with a good design and good appearance,
There is also a demand to add moisture to the road surface itself,
In order to respond to this, the paving stone blocks are laid in a scattered manner so that the paving stone blocks are provided with a space portion having a predetermined width, and the space portion formed between the paving stone blocks is filled with soil, and turfgrass is placed here. It has been proposed to vegetate etc. (hereinafter, such a paving stone block laying state is referred to as "scattered laying").

[0004]

By the way, when the paving stone blocks are laid in a scattered manner and vegetation is carried out in the space between the paving stone blocks in this way, when the paving stone blocks are laid, the paving stone blocks are laid between the paving stone blocks. It is necessary to construct one after another with relatively large intervals to form a space for vegetation. Therefore, at the time of "scattered laying" of the paving stone blocks, the paving stone blocks are laid one after another by sequentially abutting the paving stone blocks so that the intervals between the paving stone blocks are automatically set to a predetermined width (that is, joint width). Unlike the case of "contact laying", it is difficult to control the distance between the stone blocks and the position during laying work, which is a bottleneck in facilitating construction and improving workability.

On the other hand, when the paving stone blocks are scattered and the space between the paving stone blocks is filled with only the soil, the posture of each paving stone block after the laying is maintained by the resistance of the soil filled in the space. If the paving stone block is laid in a parking lot and a large load may locally act on a part of the paving stone block due to the passage of an automobile, the paving stone block may be used. The posture will gradually collapse, and the block laying surface will be disturbed, resulting in unfavorable results both practically and aesthetically.

In view of the above, the present invention aims to improve the workability and workability by facilitating the positioning and spacing of each paving stone block when laying scattered paving stone blocks, and also improving the workability and workability of the paving stone block. The present invention is made as a proposal for a paving stone positioning member that can reliably hold the paving stone and a paving stone construction method using the positioning member.

[0007]

In the present invention, the following constitution is adopted as a concrete means for solving such a problem.

In the first invention of the present application, when the plurality of paving stone blocks having a polygonal planar shape are laid in a plane at a predetermined interval, the positioning member for positioning the paving stone blocks to each other is the paving stone. A plurality of protrusions that are integrally formed in a block shape thinner than the block and that protrude outward in the plane direction with a predetermined width dimension on the outer peripheral portion, and between a pair of adjacent protrusions of the plurality of protrusions. And a plurality of fitting portions that are formed so that the corners of the paving stone block can be fitted from the plane direction.

In the second invention of the present application, when a plurality of paving stone blocks having a polygonal planar shape are laid in a plane shape at predetermined intervals to form a soil filling space between the paving stone blocks, A plurality of protrusions that are integrally formed in a block shape thinner than the paving stone block and that protrude outward in the plane direction with a predetermined width dimension on the outer peripheral portion, and a pair of adjacent protrusions of the plurality of protrusions. Using a positioning member formed with a plurality of fitting portions each formed between the parts and adapted to be able to fit the corner portion of the paving stone block from the plane direction, of the positioning member placed on the installation surface. By laying the plurality of paving stone blocks sequentially in the plane direction while inserting one corner of each of the plurality of paving stone blocks into each of the fitting portions, a flat surface of the plurality of paving stone blocks is obtained. Together occupy performed in the direction of positioning, it is characterized by forming the soil filling space gap portion between the pair of paving stones blocks mutually adjacent across the protrusions of the positioning member.

[0010]

According to the present invention, the following actions and effects can be obtained by adopting such a configuration. That is, the positioning member is integrally formed in a block shape thinner than the paving stone block, and the outer peripheral portion thereof has a plurality of protruding portions protruding outward in the plane direction with a predetermined width dimension, and the plurality of protruding portions. Since a plurality of fitting portions that are formed between a pair of adjacent protrusions of the paving stone block and that allow the corner portions of the paving stone block to be fitted from the plane direction are formed respectively, use such a positioning member. When laying a plurality of paving stone blocks, the plurality of paving stones are fitted into the respective fitting portions of the positioning member placed on the installation surface while fitting one corner of the plurality of paving stone blocks, respectively. While laying the blocks in the plane direction sequentially, the positioning of the plurality of paving stone blocks in the plane direction is performed,
The soil filling space is automatically formed in the gap between the pair of paving stone blocks that are adjacent to each other with the protrusions of the positioning member interposed therebetween. Therefore, when laying a plurality of paving stone blocks at a predetermined interval without contacting each other, by sequentially laying the paving stone blocks while fitting the corners of the paving stone blocks into the fitting portions of the positioning member, Since the interval management and position management are performed automatically, the construction is easy and the workability is high, and even the pavement road surface with vegetation between the pavement blocks can be constructed at a lower cost. It can be provided.

When a plurality of paving stone blocks are laid using the positioning member, the posture of each paving stone block can be maintained.
Not only the resistance of the soil filled in the space between the paving stone blocks but also the rigidity of the positioning member allows the posture holding effect of each paving stone block to be high. On the other hand, even in the case where a local load is applied to a part of the paving stone block, disturbance of the posture of each paving stone block is prevented as much as possible, and the paving stone block laying surface is maintained satisfactorily for a long period of time. It is something.
