DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a cross-sectional view of a ground pavement structure according to an embodiment of the present invention, FIG. 2 is a plan view of the ground pavement structure, and FIG. 3 is a ground paving joint material of the present invention used in the ground pavement structure. It is a perspective view.

In the ground pavement structure of this embodiment, a sand layer 3 is provided on a ground 1 via a crusher orchid layer 2 to provide a surface drainage function, and a large number of water-permeable layers are provided on the sand layer 3. The surface materials 4 are laid flat and paved. Then, the joint material 6 for ground pavement of the present invention is arranged at a joint portion of the surface material 4, the rising plate 6 a of the joint material 6 is sandwiched between joints between the surface materials, and the edge portion of the surface material 4. Is supported by the bottom plate 6b of the joint material 6.

The crusher orchid layer 2 has an average particle size of 30 to
This is a layer formed by spreading a crusher run of about 40 mm on the ground 1. The crusher orchid layer 2 serves as a water storage tank for temporarily storing rainwater until rainwater that sequentially permeates through the permeable surface material 4 and the sand layer 3 during rainfall gradually penetrates underground and is drained. Therefore, it is desirable to form the layer so as to have a thickness of about 10 to 30 cm. If it is less than 10 cm, the water storage amount may be insufficient, and if it is more than 30 cm, a large amount of crusher orchid is required, so that the construction cost increases. When the surface drainage function is not provided, the crusher run layer 2 does not need to be provided below the sand layer 1.

The sand layer 3 is a layer formed by spreading washing sand, sea sand, river sand and the like on the crusher run layer 2. The thickness of the sand layer 3 may be any thickness as long as it can cover the uneven surface of the crusher orchid layer 2 and lay the surface materials 4 flat, so that it is appropriate to be about 3 to 10 cm. The sand layer 3 is made of a resin binder such as an acrylic resin, a phenol resin, an epoxy resin, or the like.
Sand may be solidified by blending at a ratio of 5 parts by weight. By consolidating the sand in this way, there is an advantage that sand can be reliably prevented from flowing out due to rainwater or the like.

As the surface material 4 having water permeability, it is possible to use all plate-like bodies having internal water-permeable voids formed by shaving pebbles or other inorganic particulate matter into a plate shape with cement or various binders. Further, a surface material or the like in which the above-described plate-like body is fitted in a square frame having a bottom and a drain hole is also preferably used. The thickness of the surface material 4 and the length of one side are not particularly limited, but those having a thickness of about 2 to 8 cm and a side of about 20 to 50 cm are preferably used. In the ground pavement structure of this embodiment, a water-permeable surface material 4 is laid in order to provide a surface drainage function. However, when a surface drainage function is not provided, a non-water-permeable surface material may be used. .

The ground pavement joint material 6 used in the ground pavement structure is made of a rigid rubber, for example, an elastomer such as an ABS rubber. As shown in FIGS. 1 and 3, the joint material 6 includes a rising plate 6 a sandwiched between joints between the surface materials 4, and a bottom plate 6 b projecting to both sides from a lower end of the rising plate 6 a. The rising plate 6a is formed in a cross-girder shape, and the bottom plate 6b has a wide cross-girder flat shape. The bottom plate 6b may be formed at a lower portion of the rising plate 6a, that is, at a lower end of the rising plate 6a or a portion slightly above the lower end. When the bottom plate 6b is formed in a portion slightly above the lower end of the rising plate 6a,
When laying joint materials 6 on the sand layer 3 as described later,
There is an advantage that the lower end of the riser plate 6a protruding downward from the bottom plate 6b cuts into the sand layer 3 to prevent displacement.

The height of the rising plate 6a is set to be equal to or slightly smaller than the thickness of the surface member 4 described above. The inner dimension A of the rectangular frame portion of the rising plate 6a is: The length is set slightly larger than the length of one side of the surface member 4 described above. Therefore, the surface material 4 is fitted into the inner space of the rectangular frame portion of the rising plate 6a with substantially no gap. The protruding dimension B of the protruding portion protruding from the rectangular frame portion of the rising plate 6a is set to の of the inner size A of the rectangular frame portion. Therefore, when the joint members 6 are laid out vertically and horizontally as shown in FIG. 2, both the rising plate 6a and the bottom plate 6b are continuous vertically and horizontally, and a grid frame is formed by the rising plate 6a. If the surface material 4 is fitted into each of the square spaces, the rising plate 6a is sandwiched between joints between the surface materials 4, and
The back surface of the edge portion of the surface material 4 is supported by the bottom plate 6b, and the surface materials 4 can be efficiently laid.

Further, a plurality of convex ribs 6c are formed on the upper surface of the bottom plate 6b at appropriate intervals. The convex ribs 6c are formed to stably support the back surface of the edge portion of the surface material 4, and are thin linear ribs having a height and width of about 1 mm. When such a convex rib 6c is formed, even if the bottom plate 6b is slightly deformed along the undulation of the surface of the sand layer 3, or if the sand is caught between the bottom plate 6b and the back surface of the edge of the surface material 4, The surface ribs 4 can be stably supported by the convex ribs 6c without rattling.

The width C of the bottom plate 6b is desirably set to 4 cm or more. If the width C is smaller than 4 cm, the area of the bottom plate 6b becomes too small, so that the bottom plate 6b is easily buried in the sand layer 3. A more preferred width dimension C of the bottom plate 6c is about 6 to 16 cm. In addition, the starting plate 6a
If the thickness of the bottom plate 6b is about 2 to 5 mm, the strength is sufficient.

The above-mentioned ground pavement structure is constructed by arranging cross-girder joint members 6 on the sand layer 3 vertically and horizontally to form a continuous lattice frame, and fitting the surface members 4 into the respective rectangular spaces. It can be constructed efficiently and each surface material 4
Is supported by the convex ribs 6c of the bottom plate 6b of the joint material 6, so that even if a load such as a pedestrian repeatedly acts on the edge of the surface material 4, the edge of the surface material 4 Does not penetrate the sand layer 3. In addition, the joint material 6 prevents the sand under the joint between the surface materials 4 from flowing away by rainwater or the like. Therefore, the problem that the edge of the surface material bites into the sand layer as in the conventional ground pavement structure and the sand below the joint portion is washed away by rainwater or the like, and the problem that the surface material is inclined or rattles is sufficiently caused. Will be resolved. Moreover, the surface material 4
Since the rising plate 6a of the joint material 6 is sandwiched between joints between the joints, the edges of the surface material 4 abut against each other to be broken, sand in the sand layer 3 rises out of the joint, This eliminates the problem of weeds growing, and can maintain a beautiful pavement landscape over a long period of time. Even if sand having a particle size larger than the height of the convex rib 6c is caught between the bottom plate 6b of the joint material 6 and the back surface of the edge portion of the surface material 4, the sand is buried in the bottom plate 6b of the elastomer. There is no fear that the surface material 4 tilts or rattles due to the sand that has entered. During rainfall, the rainwater is permeable surface material 4
And the sand layer 3 is sequentially transmitted to the crusher orchid layer 2 and gradually drained to the underground, so that a good surface drainage effect can be obtained.

FIG. 4 is a perspective view of a joint material for ground pavement according to another embodiment of the present invention, FIG. 5 is a plan view of the joint material laid vertically and horizontally, and FIG. 6 is a side view thereof.

The joint material 60 for ground paving is made of the same elastomer as the joint material 6 described above, and its rising plate 60a is formed in an L-shape, and the bottom plate 60b is also formed in a wide L-shaped planar shape. have. Both ends of the L-shaped rising plate 60a protrude from both ends of the bottom plate 60b, and the protruding dimension D is a dimension obtained by subtracting the thickness E of the rising plate 60a from the width C of the bottom plate 60b. It is set to 1/2.

Therefore, when the joint members 60 are laid out vertically and horizontally as shown in FIG. 5, as shown in FIG.
0a is a bottom plate 60 of joint material 60 in which the protruding portions at both ends are adjacent.
b, the end face of the rising plate 60a abuts against the side surface of the rising plate 60a of the joint material 60 adjacent thereto, and as shown in FIG. 5, both the rising plate 60a and the bottom plate 60b are continuous vertically and horizontally. A grid frame is formed by the raising plate 60a.
Therefore, the surface material 4 is placed in each square space of the lattice frame.
Is inserted, the rising plate 60a is sandwiched between the joints between the surface materials 4, and the back surface of the edge of the surface material 4 is supported by the bottom plate 60b. The surface materials 4 can be laid well and arranged.

In this joint material 60, no convex rib is formed on the upper surface of the bottom plate 60b. However, a convex rib similar to that described above is formed to further improve the support stability of the back surface of the edge of the surface material 4. May be. The other configuration is the same as that of the joint material 6 described above, and thus the description is omitted.

The joint material 60 for pavement on the ground is applied to the sand layer 3
On the joint of the surface material 4 on the
0a between the joints between the surface materials,
In the case where the back surface of the edge portion is supported by the bottom plate 60b and pavement is performed, the same excellent operational effects as those in the case where pavement is performed using the joint material 6 for ground pavement described above can be obtained.

[0033]

As is apparent from the above description, according to the present invention, even when a load repeatedly acts on the edge of the surface material, the edge of the surface material does not bite into the sand layer, and The sand below the joints between the timbers is not easily washed away by rainwater, etc.
The surface material can be sufficiently prevented from tilting and rattling, and the edges of the surface material can be abutted against each other, causing breakage, sand in the sand layer rising out of the joint, and weeds growing at the joint. Since it is possible to prevent the pavement from being performed, a remarkable effect of maintaining a beautiful pavement landscape for a long period of time is achieved. And since the work of laying the joint material and the surface material can also be performed efficiently, the workability is improved, and the sand may be rattled even if sand is caught between the back surface of the edge of the surface material and the bottom plate of the joint material. In addition, a good surface drainage effect can be obtained.
