Description

TECHNICAL FIELD The present invention relates to a drainage support base used when laying an artificial turf on an installation section, and more particularly, to improve the drainage between the artificial turf and the installation section, and to improve the installation state. 1. The drainage support base for artificial turf which makes it difficult for the artificial turf to be rolled up by a strong wind.

Natural turf surfaces require continuous maintenance such as weeding, fertilizing, lawn mowing, and watering, whereas artificial turf surfaces basically require no maintenance. popular in The artificial turf surface is formed by laying artificial turf, which is constructed by planting bundle-like artificial turf pieces on the upper surface of the sheet base material, on the ground, concrete surface, mortar surface, asphalt surface, or asphalt surface.

When laying artificial turf on a concrete surface, mortar surface, asphalt surface, or asphalt surface (hereinafter referred to as a concrete surface, etc.), the lower surface of the artificial turf surface is brought into direct contact with the concrete surface, etc. rice field. Therefore, when it rains on the artificial turf surface, even if water flows down along the slope of the concrete surface, it tends to remain wet and damp, causing mold and algae to grow on the surrounding concrete surface. The surface of the artificial turf and its surrounding area is spoiled by the discoloration of green, etc., and it is also unsanitary. In addition, there is a problem that the artificial turf laid in a place that is easily affected by the wind is easily blown up by a strong wind.

As a technique for solving the above-mentioned problem of poor drainage, a cushioning material for drainage is used in which small holes and legs are provided in the base plate, and this cushioning material is laid on the upper surface of the water-permeable asphalt. Patent Document 1 proposes a structure in which artificial grass is laid on the upper surface. This structure has the advantage that rainwater drops from the small holes, and the dropped rainwater is discharged from the water-permeable as-con in a drainage channel formed between the substrate portion and the water-permeable as-con. was there. Patent Document 1 describes that "artificial turf is laid on the upper surface of the cushioning material that also serves as drainage," but does not describe that "artificial grass is simply placed on the upper surface of the cushioning material that also serves as drainage." However, Patent Document 1 only mentions "laying artificial grass" consistently, and there is only one word about "fixing artificial grass by gluing it to the upper surface of the cushioning material that also serves as drainage". No description. Therefore, "laying artificial turf on the upper surface of the cushioning material for drainage" in the structure of Patent Document 1 means "simply placing the artificial turf on the upper surface of the cushioning material for drainage without fixing means. ” is interpreted as meaning.

Although the structure according to Patent Document 1 has the above-described advantage in terms of drainage, the structure is affected by the wind because the artificial turf is simply placed on the upper surface of the cushioning material that also serves as drainage. If the artificial turf is constructed in a place where it is easy to wind, it is considered that there is a problem that the artificial turf is easily blown up by strong winds.

As a means for solving the problem that the laid artificial turf mat tends to be rolled up by strong winds, as in the artificial turf mat described in Patent Document 2, the artificial turf is screwed to the resin mat using a screw member. Although means for holding the artificial turf together can be considered, there has been the problem that the work of fixing the artificial turf to the resin mat using a large number of screw members requires a lot of time and effort, resulting in poor workability.

The leg portion 16 has a strength capable of supporting the load applied to the mounting plate portion 13, and the drainage channel 19 (see FIG. 1) formed between the mounting plate portion 13 and the installation portion 3. ~2) is stably retained. Among the leg portions 16 having such a configuration, when the leg portion 16 is configured as the cylindrical leg portion 16b, the cylindrical leg portion 16b1 along the cutting groove portion 67 is formed as shown in FIG. , and its peripheral wall portion 72 is partially cut off at the cutting groove portion 67 . Further, when the leg portion 16 is configured by the bottom plate portion 61 (FIGS. 7 and 8), the lower surface of the bottom plate portion 61 (the surface on which the installation portion 3 is placed) 64 (FIGS. 6 and 8) 9) have a large area, so that the load applied to the mounting plate portion 13 can be stably supported. In this embodiment, these leg portions 16 are provided on the lower surfaces of the surrounding frame 39, the vertical frame 42, and the horizontal frame 45 in a substantially evenly dispersed state.

Further, the square plate-shaped mounting plate portion 13 is configured such that the respective side edge portions 41, 41, 43, 43 thereof can be detachably connected to each other by means of concave-convex fitting. 5 to 6, 8, and 11 to 12 show one aspect thereof. Referring to FIG. 7, which is an enlarged view, each of the two peripheral edges 41 and 43 forming a right angle with each other is provided with an odd-numbered vertical frame 42 when viewed in the horizontal direction from the vertical peripheral edge 41. The ends 73 and the ends 75 of the odd-numbered horizontal frames 45 when viewed in the vertical direction from the horizontal edge 43 are T-shaped, for example, as shown in FIGS. A connecting projection 76 is provided. Further, on each of the other two side edges (the two side edges 41 and 43 in the upper left part of FIG. 5) that are perpendicular to each other and are located on the diagonal side, the connection convex portion 76 and the attachment/detachment are provided. A connection recess forming portion 79 having a connection recess 77 with an open bottom end that can be fitted is provided (FIGS. 5, 8 and 11). In this embodiment, as shown in FIGS. 2 and 12, the lower end 17 of the connecting convex portion 76 and the lower end 17 of the connecting concave portion forming portion 79 ride on the installation portion 3 as shown in FIG. .

As shown in FIG. 12, the connection projection 76 of one drainage support 1a is fitted into the connection recess 77 of the other drainage support 1b adjacent to the drainage support 1a. As a result, the drainage supports 1, 1 can be sequentially connected to form an artificial turf installation surface 80 (FIGS. 1 and 2, FIG. 12) having a required area. On the artificial turf installation surface 80 formed by sequentially connecting the drainage support bases 1, 1, the adhesion surface 33 and the adhesion surface 63 are provided in a substantially evenly dispersed state (Fig. 5). 6, Fig. 8).

Next, a work process for laying the artificial turf 2 on the installation portion 3 using the drainage support base 1 having such a configuration will be described. The drainage support base 1 is placed on the installation portion (such as the concrete surface) 3 where the artificial turf 2 is to be installed, with the lower ends 17 of the leg portions 16 placed thereon. As a result, as shown in FIGS. 1 and 2, the drainage channel 19 having a vertical height of about 5 mm is formed between the installation portion 3 and the mounting plate portion 13. As shown in FIG. Then, the drain hole 20 communicates with the drain channel 19 . This installation is carried out by arranging a required number of the drainage support bases 1 side by side according to the area of the installation portion 3. At this time, as shown in FIG. is fitted into the connecting recess 77 of the other drainage support base 1b adjacent to the drainage support base 1a. As a result, the drainage support bases 1, 1 are sequentially connected to each other.

When the drainage support 1 is installed on the installation portion 3 in this manner, the drainage support 1 has a square plate shape as described above. A case may arise where the support base 1 does not fit into the shape. In this case, the cutting edge of a knife cutter is inserted into the required cutting groove 67 (FIG. 10(B)) to cut the groove bottom 69 to excise the unnecessary portion. As a result, the artificial turf can be laid on the installation portion with good appearance.

After forming the artificial turf mounting surface 80 (FIG. 12) in this way, as shown in FIG. Adhesive tape 30 is continuously adhered. Since the upper surface of the sticking piece 56 (FIG. 7) that constitutes the sticking surface 33 is flat, the bottom sticking portion 31 (FIGS. ) has a high adhesive strength.

When the artificial turf 2 is placed on the artificial turf mounting surface 80 thus formed (FIG. 1), the lower surface of the sheet base material 6 of the artificial turf 2 is placed as described with reference to FIG. Since a large number of protrusions 10 are protruded from the portion 11 in a dispersed state, some of the fitting protrusions 23 are located in the fitting recesses 21 as shown in FIG. becomes. When the upper surface portion 35 (FIG. 1) of the artificial turf 2 is pressed toward the insertion recess 21 in a state where the artificial turf 2 is placed in this way, the covering adhesive portion 29 is formed as shown in FIG. 4(C). can be elongated and deformed downward into a concave shape. Since the surrounding adhesive portion 32 is firmly adhered to the adhesion surface 33, the recessed elongation deformation is reliably performed without drawing the surrounding portion of the covering adhesive portion 29 into the fitting recess 21 side. . As a result, the convex outer surface 36 of the fitting convex portion 23 is adhered to the covering adhesive portion 29 that is elongated and deformed into a concave shape. Due to the increase in adhesion force due to the increase in adhesion area associated with such an adhesion state, the artificial turf 2 can be adhered to the adhesion surface 33 more firmly.

By the way, for example, as shown in FIG. 13, an adhesive tape 30 in which a lower adhesive portion 31 is attached to a flat surface 83 (flat surface when the fitting recess 21 is not provided on the adhesive surface) 83 Even if the convex portion 10 is pressed against the upper surface adhesive portion 85, the tip portion 86 of the convex portion 10 is only adhered to the upper surface adhesive portion 85 in a dot shape, so the adhesive strength is weak. . On the other hand, according to the present invention in which the fitting convex portion 23 can be pressed toward the fitting concave portion 21, the adhesive force can be increased by increasing the bonding area as described above. The artificial turf 2 can be prevented from being rolled up by a strong wind.

When it rains on the artificial turf surface 2 formed in this manner, the rainwater reaches the mounting plate portion 13 through the water passage holes 12 (FIG. 2), and then passes through the drainage holes 20 to drain the rainwater. It reaches the path 19 and flows down along the slope of the upper surface (concrete surface or the like) of the installation portion 3 to be discharged. As a result, it is possible to solve the conventional problems, that is, the problem of damage to the aesthetic appearance and the problem of unsanitary conditions caused by the growth of mold and algae on the area where the artificial turf is laid.

Further, since the laid artificial grass 2 is firmly adhered to the mounting plate portion 13 via the adhesive tape 30, the laid artificial grass 2 is less likely to be rolled up by strong wind. In the present embodiment, as described above, the adhesive surface 33 is provided in a substantially evenly dispersed state over the entire surface on which the artificial turf is installed. can. In addition, the function and effect of preventing the curling up can be obtained only by bonding the artificial grass 2 and the mounting plate portion 13 via the adhesive tape 30 after installing the drainage support base 1 on the installation portion 3. Therefore, the laying work for laying the artificial turf 2 on the installation portion 3 can be performed with good workability.

When installing the drainage support base 1 on the installation portion (concrete surface or the like) 3, as shown in FIG. When the upper surface adhesive portion 62 of the adhesive tape 30 is adhered and the lower surface adhesive portion 31 of the adhesive tape 30 is adhered to the installation portion 3, the adhesion force prevents the installation portion 3 from being damaged by strong winds. It is possible to improve the stability of the installation state of the drainage support base 1 against.
