DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paving stone to be laid in a park, a garden or a garden of a general house, and more particularly to a paving stone which is laid in a lawn as a passageway or a partition for a retaining wall, or in a lawn. The purpose of the present invention is to provide a lawn surface paving stone having a novel structure intended to be laid in order to form a unique X-terrier design in a dotted state.

[0002]

2. Description of the Related Art Generally, beautification of the surface of a pedestrian walkway from a gate to an entrance of a house, a parking lot, a plaza on a building roof, a passage on a factory site, a park, etc. In order to prevent the mud from becoming muddy, the most commonly used method up to now is to spread tiles and blocks made of various materials and shapes according to a predetermined design and cover the entire surface of the ground. There is a pavement construction that covers up the area.

[0003] In this paving stone construction, first, a crushed stone ground is formed, a concrete foundation is struck while providing an expansion joint, and a mortar foundation is provided by stacking, and a desired tile or block is laid thereon. In order to arrange the blocks in an orderly manner as determined, not only considerable skill is required, but also the work process becomes complicated and the construction takes a considerable amount of time. We had to be prepared for the construction costs which were considerably higher than other pavements such as construction and asphalt pavement.

[0004] For this reason, in the case of an owner who cannot afford the economic reason or the construction period, the paving stone construction is abandoned, and simple concrete or asphalt pavement is required. In addition, it has the drawback that it has a strong summer reflection, makes heat and dryness more severe, makes it easy to fly dust, and makes it visually scorching,
It is unsuitable for construction of parks and gardens, and therefore, in parks and gardens, construction means that does not require the cost and time of paving stones and can avoid disadvantages such as concrete casting and asphalt pavement. The turf is heavily used, and recently the breeding has been improved, providing a durable lawn that can withstand the entry of passenger cars, such as Tifton Shiva used in golf courses and various other stadiums It is becoming.

[0005] Lawn grass has an effect of excelling in aesthetics due to its green color, and has an effect of relieving the strong sunshine in summer, and has the advantage of solidifying the ground by forming roots and preventing muddy surface. On the other hand, it has the drawback that maintenance and management becomes extremely complicated because it needs to pay attention to sunshine, drying, draining, etc., and regular maintenance that can withstand the trample of cars and people. In particular, during the curing period of about two months after the lawn is laid, treading is basically prohibited, and the use in the lawn surface is restricted until it is firmly established.

[0006] Therefore, rectangular parallelepiped blocks are combined in a girder form and laid continuously, and the underground communicating lawn area formed by the blocks, ie, the direction in which the lawn roots extend, is blocked by a concrete layer or the like. The lawn is stretched only in an area that is maintained continuously in the ground without being covered, and the car and people are trampled by the block by curing, and the lawn is cultivated soundly and the pavement surface during curing is secured In addition, a construction method or the like that enables the use within the curing period to a certain extent and completes the construction within a short period of time is also employed.

However, the lawn has two kinds of stems, a creeping stalk extending under the ground and the ground surface, and an upright stalk with leaves, and the periphery is surrounded by blocks as described above. In addition, the growth of the creeping stalk, which is indispensable for the growth of the lawn, is hindered, the roots are weak, good growth is not secured, and it is easily susceptible to pests, etc., which shortens the life of the lawn. It had something.

In view of the above-described properties of the lawn, the present invention is capable of forming an underground communicating lawn covering area and constructing the lawn so as not to hinder the growth and elongation of the stolon. It is possible, and even if it is not a specialist, it is possible to perform a certain amount of construction, and also focuses on the necessity of paving stones that can be laid easily and accurately in the layout as designed, We started development and research, repeated trial and error for many years, and repeated many trials and experiments.As a result, we finally succeeded in completing and commercializing a lawn surface paving stone with a new structure. Yes, below,
The configuration will be described in detail with an embodiment representative of the present invention shown in the drawings.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As will be clearly understood from the embodiments of the present invention shown in the drawings, the lawn paving stone included in the present invention basically has the following configuration. . That is, while the upper surface of the rectangular paving stone main body is used as the paving stone surface portion exposed to the ground as it is, the peripheral wall portions at both ends in the longitudinal direction of the paving stone main body are also directly used as the underground joining surface portion,
In the remaining two peripheral wall portions, one end side of a non-overlapping portion is respectively formed in the underground jointed surface portion, and around the center of the paving stone surface portion, both the peripheral wall portions in which the underground jointed surface portion is formed by the paving stone body. The blocks or tiles are formed into a rectangular block or tile in such a manner that the blocks or tiles communicate with each other by one or more grooves, and the blocks or tiles adjacent to each other are laid and joined to each other by a corresponding underground joint surface and an underground joint surface. Combine in a girder-like arrangement to secure the underground communication lawn covering area in the portion surrounded by the adjacent paving stone bodies, while the groove part that divides the paving stone surface part exposed on the ground surface is described above. It is a paving stone for a lawn surface whose main point is a side-by-side grass-covering area that connects the underground communication grass-covering areas.

The paving stone body is a main part of the paving stone of the present invention, is buried in the ground, has a paving stone surface integrally protruding above it, and has an underground joining surface from its peripheral wall. Has a function of enabling to extend and form in the horizontal direction, and its material and shape can be appropriately set as needed. That is, for example, stone or concrete, bricks, tiles, pottery, ceramics, glass, synthetic resin, or a composite material of these can be adopted, but not included in these, but a material having properties equivalent to them, Alternatively, it is possible to adopt a porous material having air permeability, etc., and it can be formed in a block shape or a tile shape by changing the thickness dimension. Alternatively, a color or a pattern may be applied to the surface by adding a coloring agent or the like.

The paving stone surface portion is exposed on the ground surface, and has a function of directly contacting human feet or car tires to receive a tread pressure, and a function of securing contrast with the lawn and a decorative pattern by its own combination pattern. Therefore, it should have hardness to withstand tread pressure and durability against abrasion.Also, select a material with a high coefficient of friction or use an uneven surface shape to prevent slip. It can be very convenient to enhance the function or to form a fine drainage groove partially or over the entire surface to promote drainage, and it can be made by coloring, drawing, printing, or uneven pattern etc. Further, the decoration function can be enhanced.

Since the paving stone surface is formed integrally with the paving stone body above, it is formed of the same material as the paving stone main body at the molding stage. Adhesive materials such as stone, concrete, bricks, tiles, pottery, ceramics, glass, natural rubber, synthetic resins, or their composite materials, or other materials with equivalent functions, are bonded to the paving stone body. It may be integrated by conventional means, and it is formed in a shape substantially equivalent to the planar shape of the paving stone body, and the surface subjected to treading is mirror-finished, the crushed surface of the stone material as it is, or reproduced and molded And the like. In addition, chamfers and flank surfaces can be formed at the edges to facilitate the lawn clipping operation. In addition, a colorant is added to the cement when forming a concrete molded product, and in the case of shaving from a stone, a plurality of colors or stones having different textures are used in advance. It is also possible to produce paving stones and to perform construction and laying in which one or more colors are interwoven.

The underground joint has a function of forming an underground joint at a peripheral wall of the paving stone main body or at a position protruding outward from the peripheral wall, and supporting and fixing the underground joint at a predetermined position. If it is protruded from the surrounding wall, it must be provided below the paving stone surface and at a position buried in the ground with the paving stone body, and on the top of it, a lawn area for flat laying If necessary, it is possible to form a water hole, a communication hole or a communication groove for ventilation, which communicates in a vertical direction so as to further promote the crawling growth of the lawn, and it is also possible to form a paving stone. It should be molded integrally with the same material as the body, or a material different from the paving stone body, such as stone, concrete, brick, tile, pottery, ceramic, glass, synthetic resin, or these Composites, or formed from an outer material having the same functions that are not included in these, retrofit the peripheral wall portion of the pavement body, it is also possible to become integrated.

The underground joint surface serves as a positioning target when the other paving stones are accurately positioned and joined to each other, and is provided directly on the peripheral wall of the paving stone body. Alternatively, it may be formed on the tip end surface of the underground joint. Furthermore, a configuration that promotes bonding using mortar, adhesive, etc., such as applying a paint of a different color from the paving stone main body, paving stone surface portion, underground joint, or forming a coating film having an uneven shape In order to clarify the bonding area, or to form a concave part in the part corresponding to the underground joint surface of the underground joint, separate parts with different colors, textures, surface irregularities, etc. are attached by bonding or the like. The surface part of this separate part can be used as an underground joint surface part to add a function to clarify the target position of the joint. And it may be designed to promote bonding with an adhesive, or to form a painted surface with fine irregularities such as a rough ground part, so as to increase the bonding area of mortar or adhesive it can.

The underground joint surface portion is a portion to which the underground joint surface portion is joined, and while ensuring the joint strength,
A structure that serves as a guide for the joining position and promotes bonding with mortar or an adhesive similarly to the underground joint surface, for example, a color different from the paving stone body, paving stone surface and underground joint By applying a paint, or by applying a coating having an uneven shape, it is possible to clarify the joining range, a concave portion is formed in a portion corresponding to an underground joined surface portion, and Separate parts with different colors, textures, surface irregularities, etc. are fitted into the recesses, and the surface part of this separate part is used as the underground joint surface to clarify the target position for joining. It is also possible to form a recessed part that can be fitted with an underground joint and use this as the underground joint surface, and also to adhere the surface as a smooth surface without unevenness by painting To promote bonding by the agent There is formed a painted surface of, it can also be made that is configured to increase the bonding area of the mortar or adhesive.

The underground communication lawn is formed by combining and surrounding a plurality of lawn paving stones.
It is a ground portion that is exposed on the ground, and is a region that secures water permeability and air permeability to the underground, and enables rooting of grass in the ground. Further, the horizontal crawling lawn area is an area that continuously crosses a part of the upper part of the paving stone for in-lawn plane so as to straddle the adjacent underground communication lawn area, and enables the lawn to grow by crawling. In the following, the structure of the present invention will be described in detail, together with the embodiment shown in the drawings.
