BEST MODE FOR CARRYING OUT THE INVENTION First, a first embodiment of the present invention will be described below with reference to FIGS.

In the drawing, reference numeral 1 denotes a joint material, and this joint material 1 comprises a joint material main body 2 made of an extruded material of synthetic resin and a double-sided tape 3 provided with an adhesive. In this embodiment, the joint material main body 2 corresponds to the band-shaped body referred to in the present invention, and the double-sided tape 3 corresponds to the attaching means referred to in the present invention.

The joint material 1 is, for example, as shown in FIG. 3, one of the four side surfaces 4a of the paving water-permeable block 4 (hereinafter, simply referred to as water-permeable block) formed in a square shape in plan view. By arranging the water-permeable blocks 4 so as to be attached in an L shape over two adjacent sides, the joint portion 5 surrounding the entire circumference of each water-permeable block 4 is formed.

In this embodiment, the joint material main body 2 is
Since it is made of a semi-rigid PVC (polyvinyl chloride) which is a flexible material and has a hardness of about 80 degrees and is non-foamed, it itself is impermeable. The joint main body 2 may be made of soft PVC, polyethylene, or other various synthetic resins or rubber materials.

As shown in FIG. 5, the joint material main body 2 is formed by an extrusion molding machine 6, and a strip-shaped body 11 cut out from a long strip-shaped raw material 8 wound by a winding machine 7 to a required length. It consists of

In this embodiment, the strip-shaped body 11 which is the joint material main body 2 has a longitudinal direction of the strip-shaped material 8 on one surface (hereinafter simply referred to as surface) side of the strip-shaped material, as can be seen from FIGS. Four rib portions 12a, 12b, which are continuous in the direction
12c and 12d are formed so as to be separated from each other in the width direction of the band-shaped material 8, and a front surface (hereinafter, simply referred to as a back surface) side on the back side with respect to this surface is formed flat.

The strip 11 is cut into a length corresponding to the length 2L of two adjacent sides of the water-permeable block 4, and the strip 11 has a midpoint in the longitudinal direction, that is, a strip. The four rib portions 12a, 12b, 12c, 12d are provided at a position of a length L from one end of the body 11 to the strip-shaped body 11.
A notch 13 is formed in the width direction of the to form the joint material main body 2.

The length of the joint main body 2, that is, the length dimension at which the band-shaped body 11 is cut is such that when the band-shaped body 11 is made of a material having high elasticity, the joint material 1 is attached to the water-permeable block 4. Considering the elongation of the joint main body 2 caused by the work of wearing, it is set to be slightly shorter than the 2L, and by sticking, the sticking is performed so as to cover the entire required side surface 4a of the water permeable block 4. Is preferred.

Further, the rib portion formed on the belt-shaped body 11 has four ribs.
The number is not limited to books, and may be an appropriate number such as three or five. Further, the notch 13 may be formed on the back surface side on which the sticking means is installed, and in that case, the rib portion on the surface of the strip 11 is prevented from being notched by the notch 13. be able to.

In the joint material main body 2 of this embodiment, the width dimension W is 40 mm, and the rib portion 1 is formed from the back surface.
The thickness up to the tip of 2a, 12d is 2.5 mm, rib part 1
The thickness of the 2b and 12c to the tip is 2.0mm, and the thickness between the ribs 12a, 12b, 12c and 12d is 1.5m.
m.

In such a joint material main body 2, a double-sided tape 3 is attached to the central portion in the width direction of the back surface which is formed flat so as to extend in the longitudinal direction of the joint material main body 2.

The double-sided tape 3 in this embodiment is
This is a so-called industrial double-sided tape in which an acrylic resin adhesive is applied to both sides of a base material.

In this embodiment, the both side edges of the double-sided tape 3 mounted on the back surface of the joint material main body 2 are the two rib portions 12b at the center on the front surface side of the joint material main body 2. It is located behind 12c, so that both side edges of the double-sided tape 3 are pressed against the side surface 4a of the water-permeable block 4 to be surely attached thereto.

In the joint material 1 as described above, the notch portion 13 is aligned with the corner portion of the water-permeable block 4 so that the back side on which the double-sided tape 3 is installed faces the side surface 4a of the water-permeable block 4. The block 4 is pressed against and attached to the side surface 4a (see FIG. 4).

As described above, since the joint material is attached by aligning the notch 13 of the joint material 1 with the corner of the water permeable block 4, when the joint material 1 is attached to the water permeable block 4. The reference position for alignment is clear at the central position of the joint material 1, and the workability of mounting the joint material 1 on the water-permeable block 4 is good.

In addition, in the portion which is to be bent when the joint material 1 is attached to the water permeable block 4, the joint material 1
It is easy to bend the joint material 1 along the planar shape of the water-permeable block 4 because the cross-section coefficient of the water-permeable block 4 is small, and the joint material 1 curves at the corners of the water-permeable block 4 and rises from the side surface of the water-permeable block. There is little risk of peeling, and in this sense also the workability of mounting the joint material 1 on the water-permeable block 4 is good.

In the water permeable block 4 of this embodiment, for example, cement is used as a binder to bond the aggregates to each other, and the surface thereof is provided with fine water-permeable holes which are continuous with the voids formed between the aggregates. The surface side of the water permeable block 4 is ground and polished, but a synthetic resin may be used as a binder, or the surface side may not be ground.

Two side surfaces 4a adjacent to each other as described above
As shown in FIG. 3, the water-permeable blocks 4 to which the joint material 1 is attached in an L-shape in plan view are arranged and installed on the roadbed 21 made of crusher run compacted on the roadbed via the cushion sand 22. It

The arrangement construction of the water permeable blocks 4 is shown in FIG.
As shown in FIG. 2, the joint material 1 is formed so that the entire circumference of each water-permeable block 4 is surrounded by the joint material 1, and the joint material 1 attached to each water-permeable block 4 constitutes a joint portion 5.

In the state in which the water-permeable blocks 4 to which the joint material 1 is adhered in this manner are arrayed to form the joint portion 5, the joint material 1 is, as shown in FIG. 3, the side surface 4a of the adjacent water-permeable block 4. It is located between and.

In this embodiment, the thickness dimension T of the water permeable block 4 is set to 60 mm, and the width dimension W of the joint material main body 2 is set to 40 mm as described above. The joint material 1 having various width dimensions is attached to the central portion in the thickness direction of the side surface 4a of the water permeable block 4.

Therefore, in the joint material 1 attached to the side surface 4a of the water-permeable block 4, the upper end of the joint material 1 is located lower than the upper surface of the water-permeable block 4, and the lower end of the joint material 1 is the water-permeable block. It is located slightly above the lower surface of No. 4.

The reason why the lower end of the joint material 1 is located slightly above the lower surface of the water-permeable block 4 is for the convenience of arrangement of the water-permeable blocks 4 as described later.

When the joint material 1 is attached to the side surface 4a of the water permeable block 4, the joint material main body 2 is water impermeable, so that the inside of the water permeable block 4 extending between the many water permeable blocks 4 arranged and arranged. The movement of the water is regulated by the joint main body 2.

Therefore, for example, even when the water permeable block 4 is constructed on the inclined roadbed 21, the water stored in the water permeable block 4 moves to the lower side through the inside of the adjacent water permeable block 4. Since it is possible to reduce concentration, the water permeable block 4 on the lower side
Can be suppressed from being submerged in water or damage to the pavement structure due to movement of water under the surface of the water permeable block 4.

When it is intended to enjoy such effects of the joint filler 1, the attachment position of the joint filler 1 on the side surface 4a of the water permeable block 4 should be made as low as possible so that the gap with the cushion sand 22 is small. It is preferable to make it small, but in this joint material 1, since an adhesive is used as the attaching means, there is an advantage that the degree of freedom in adjusting the attaching position is large.

In this embodiment having such an effect, the width dimension W of the joint material 1 is 67% of the thickness dimension T of the water permeable block 4, but the water permeable block 4 as described above is used.
In order to enjoy the effect of restricting the movement of water inside the joint material 1, the width dimension W of the joint material 1 may be 50% or more of the thickness dimension T of the water permeable block 4.

On the other hand, in this embodiment, the joint material 1
The lower end of the water permeable block 4 is located slightly above the lower surface of the water permeable block 4 because of the convenience of the arrangement of the water permeable blocks 4 as described below.

That is, when the water-permeable blocks 4 are arranged in an array, the water-permeable blocks 4 placed on the cushion sand 22 may be slightly displaced on the cushion sand 22 to adjust their positions.

In such a case, the sand S is unavoidably collected in the front side of the water permeable block 4, and when such sand S exists between the side surfaces 4a of the water permeable block 4, the sand S is water permeable. There is a possibility that the construction of the arrangement of the sex blocks 4 is disturbed.

Therefore, in this embodiment, such a space for accommodating the sand S is formed between the side surfaces 4a of the water-permeable blocks 4 on both sides below the joint material 1, and the joint material 1 is attached to the side surface 4a. This is because it is relatively easy to arrange the water-permeable blocks 4 arranged.

In this embodiment which enjoys such effects, as described above, the width dimension W of the joint material 1 is 67% of the thickness dimension T of the water permeable block 4, but in the range of 95% or less. If so, such an effect can be enjoyed.

Therefore, in order to enjoy both the effect of restricting the water movement in the water permeable block 4 and the convenience of the arrangement construction, the width dimension W of the joint material 1 is set to the water permeable block 4. Is slightly smaller than the thickness T of the water-permeable block 4, that is, the width W of the joint material 1 is 50
It may be set within the range of% -95%.

The strip-shaped body 11 forming the joint material 1 of this embodiment is formed as a continuous long strip-shaped raw material 8 by the extruder 6 as shown in FIG. 5, and the strip-shaped raw material 8 is Once wound on the winding machine 7, the cross-sectional shape of the strip-shaped material 8 is flat on the back surface side as described above, and four rib portions 12a having a substantially constant height only on the front surface side,
Since 12b, 12c, and 12d are formed, the laminated state produced by winding the strip-shaped material 8 is stable as shown in FIG. 6, and the strip-shaped material 8 can be easily wound and wound. It is convenient to handle the strip-shaped material 8 in a state where it is taken without any particular caution.

Next, the second embodiment will be described with reference to FIGS. 7 and 8. In the second embodiment, the cross-sectional shape of the strip-like body 31 forming the joint material main body 32 and the sticking means. Is different from the first embodiment,
The other points are similar to those of the first embodiment described above.

In the following, only the differences will be described, and the description of the same items as above will be omitted.

First, the strip 31 of the second embodiment.
7, the four rib portions 12a, 12b, 12c, 12d are formed on the front surface side, but on the back surface side, the wide land 3 is formed in the central portion in the width direction.
3 are formed in the longitudinal direction, and groove portions 34 are formed in parallel on both sides of the land 33 in the width direction, and the second land portion 35 having a lower protruding height than the land 33 is formed outside the groove portions 34. Are formed in the longitudinal direction.

The second land portion 35 strengthens the edge portion of the strip-shaped body 31 and maintains the shape of the strip-shaped body 31 in a desired shape.

1 is formed as a long strip-shaped material 8 by the extrusion molding machine 6 and wound by the winding machine 7 in the same manner as described above, and the laminated state of the strip-shaped body 31 at that time is as shown in FIG.
On the other hand, since the two rib portions 12b and 12c in the central portion are in contact with each other, the laminated state does not become so unstable, and there is no inconvenience as described above.

An acrylic resin adhesive layer 36 is directly formed on the land 33 of the strip 31 as described above to form a sticking means.

Land 33 to which this adhesive layer 36 is applied
Behind the two ribs 12b, 1 in the center
2c are arranged, so that when they are arranged between the side surfaces 4a of the water permeable block 4 in the same manner as described above, the pressing force by these rib portions 12b, 12c causes the adhesive layer 3 of the land 33 to be pressed.
Since 6 works to press the side surface 4a of the water permeable block 4, the joint material 37 is surely attached to the side surface 4a of the water permeable block 4 as in the case described above. The land 33 on which the adhesive layer 36 is formed is the second land portion 35.
Since it slightly protrudes (t in the figure), there is an advantage that the water-permeable block 4 can be reliably attached to the side surface 4a.

In any of the above-described embodiments, the strip-shaped body 11, which forms the joint material main body 2, 32,
Although the sticking means is provided only on the back surface of 31, the sticking means may be provided on both front and back surfaces, and needless to say, an adhesive agent may be used as the sticking means instead of an adhesive agent. Absent.
