It is characterized by the vegetation surface to be performed.

  This greening mat is composed of a rock wool mat serving as a plant culture medium and a water-impermeable sheet for improving water retention, so that the number of members can be reduced, and the production efficiency can be reduced. Is achieved. Further, by using the water-impermeable sheet on the wall surface or the inclined surface with the water-impermeable sheet side down, it becomes difficult for moisture in the rock wool mat to escape and water retention is improved. Further, by setting the thickness of the rock wool mat to 5 cm to 15 cm, it is possible to spread moisture almost throughout the rock wool mat. Thereby, it is possible to plant the rainwater sufficiently without using the water supply facility or with a simple water supply facility. Furthermore, since the vegetation surface is substantially parallel to the lamination direction of the random webs, the roots of the plants are easy to enter between the layers of the random webs, and the rooting is improved. As a result, the plant is firmly fixed to the rock wool mat.

  A greening material according to the present invention includes the plurality of greening mats described above and an integrated sheet for integrating the plurality of greening mats, and one adjacent greening mat among the plurality of greening mats. The mat and the other greening mat are laminated so that the water-impermeable sheet of the one greening mat is in contact with the end surface of the other greening mat where the water-impermeable sheet is not provided. The plurality of greening mats are characterized in that the other main surface of the pair of main surfaces is bonded to an integrated sheet and integrated.

  In this greening material, since a plurality of greening mats are integrated by the integrated sheet, the handleability is improved. In addition, one greening mat and another greening mat that are adjacent to each other are so arranged that the water-impermeable sheet of one greening mat is in contact with the end surface of the other greening mat that is not provided with the water-impermeable sheet. The water retention is ensured for each of the greening mats.

  A greening panel according to the present invention includes the above greening material and a box having a hole for storing the greening material.

  In this panel for greening, handling property and workability can be improved by storing the above greening material in a box and making it into a panel. The box is preferably composed of, for example, a box body having an upper end opened and a net such as a wire mesh that closes the upper end of the box body. The box body is preferably made of, for example, punching metal. Thus, since a box has a hole, moisture, such as rain water, can be supplied to the mat for greening through this hole. According to this greening panel, when greening the outer wall of a building or the sound insulation wall of an expressway, it is only necessary to spread this panel, and greening on a vertical wall or an inclined surface becomes easy.

  ADVANTAGE OF THE INVENTION According to this invention, the greening mat | matte which can aim at the production efficiency and improvement of water retention, the greening material provided with this greening mat, and the greening panel provided with this greening material are provided. Is done.

  Hereinafter, with reference to the attached drawings, preferred embodiments of a greening mat, a greening material, and a greening panel according to the present invention will be described in detail. In addition, the same code | symbol shall be used for the same element and the overlapping description is abbreviate | omitted. Further, the dimensional ratios in the drawings do not necessarily match those described.

  FIG. 1 is a perspective view showing a greening panel according to the present embodiment, and FIG. 2 is an exploded perspective view showing the configuration of the greening panel according to the present embodiment.

  As shown in FIGS. 1 and 2, the greening panel 1 includes a greening material 12 and boxes 5 and 52 that store the greening material 12.

  As shown in FIG. 3, the greening material 12 includes a plurality of greening mats 13 and an integrated sheet 4 for integrating the plurality of greening mats 13.

  Each greening mat 13 includes a rock wool mat 2 and a water-impermeable sheet 3 as shown in FIG.

  The rock wool mat 2 is formed to have a laminated thickness T of 5 cm to 15 cm by laminating a plurality of elongated random webs mainly composed of rock wool. The rock wool mat 2 has a pair of main surfaces 21 and 22 substantially parallel to the random web laminating direction and a pair of end surfaces 23 and 24 in the laminating direction of the rock wool mat 2.

The density of the rock wool mat 2 ^is preferably a ^{30kg / m 3 ~200kg / m 3} . If the density is lower than 30 kg / m ³ , the mat becomes soft and difficult to keep its shape, while if it is higher than 200 kg / m ³ , the mat becomes hard and the plant roots are difficult to enter inside. .

  Here, in this embodiment, one of the pair of main surfaces 21 and 22 of the rock wool mat 2 is a vegetation surface on which a plant is grown. Since the vegetation surface is substantially parallel to the lamination direction of the random webs, that is, because the vegetation surface is formed by stacking the side edges of the elongated random webs, the roots of the plants are between the layers of the random webs. It is easy to get into the back and has a good root. As a result, the plant can be firmly fixed to the rock wool mat 2. The plant grown on the vegetation surface may be a plant that is resistant to drying, and is preferably a plant that does not wither throughout the year. In particular, moss and sedum are preferred. As the moss, for example, snail or high moss is preferable.

  Moreover, it is preferable that the rock wool mat 2 is hydrophilized using a hydrophilizing agent that increases the affinity with moisture. Examples of the hydrophilizing agent include higher alcohols, alkylolamides, fatty acid esters, polyalkylene glycols, and the like. Since the rock wool mat 2 is made hydrophilic in this way, rainwater adhering to the surface of the rock wool mat 2 is diffused and held inside.

  The rock wool mat 2 can be produced, for example, as follows. First, as shown to Fig.5 (a), the random web 2A which uses rock wool as a main material is prepared. Next, as shown in FIG.5 (b), the prepared random web 2A is folded and laminated | stacked in multiple layers, and the random web laminated body 2B is obtained. Next, as shown in FIG.5 (c), the obtained random web laminated body 2B is compressed in the direction of the arrow, and the random web compression body 2C is obtained. Finally, as shown in FIG.5 (d), the obtained random web compression body 2C is cut into a predetermined dimension so that lamination | stacking thickness T may be set to 5 cm-15 cm.

  As shown in FIG. 4, the water-impermeable sheet 3 is affixed to one of a pair of end surfaces 23 and 24 of the rock wool mat 2. The water-impermeable sheet 3 is not particularly limited as long as it does not transmit moisture, and polyethylene, polyester, polypropylene, nylon, acrylic, or the like is used. The thickness of the water-impermeable sheet 3 is preferably 15 μm to 200 μm.

  As shown in FIG. 3, the greening material 12 is formed by stacking a plurality of the above-mentioned greening mats 13. At this time, among the plurality of greening mats 13, one adjacent greening mat 13 and the other greening mat 13 are different from each other in that the water-impermeable sheet 3 of the one greening mat 13 is the other greening mat 13. It laminates | stacks so that the end surface 23 in which the impermeable sheet 3 is not provided among a pair of end surfaces of this. In the present embodiment, the four greening mats 13 are laminated in this way. The plurality of laminated greening mats 13 are integrated by pasting the other main surface 22 opposite to the main surface 21 which is a vegetation surface to the integrated sheet 4. The integrated sheet 4 may be a water-permeable sheet or a water-impermeable sheet, and a nonwoven fabric, a synthetic resin sheet, a film, or the like is used. In this integrated state, the vegetation surface as a whole of the greening material 12 has a substantially square shape.

  As shown in FIGS. 1 and 2, the greening material 12 configured in this way is stored in the boxes 5 and 52 and formed into a panel. The boxes 5 and 52 have a box body 5 having an upper end opened and a net 52 such as a wire mesh that closes the upper end of the box body 5. The box body 5 has substantially the same outer shape as the greening material 12. As a material for forming the box body 5, for example, a punching metal made of stainless steel is preferably used. Thus, since the box bodies 5 and 52 have holes, water such as rainwater can be supplied to the greening material 12 through the holes.

  Next, operations and effects of the greening panel 1, the greening material 12, and the greening mat 13 according to the present embodiment will be described.

  As shown in FIGS. 1 and 2, the greening panel 1 according to the present embodiment is used by being laid on a wall surface, an inclined surface or the like so that the side of the water-impermeable sheet 3 is down. At this time, since the water-impermeable sheet 3 prevents moisture from escaping downward, water retention is improved. Moreover, since the laminated thickness T of the rock wool mat 2 is 5 cm to 15 cm, the water impervious sheet 3 prevents the water from falling downward, and the water accumulated in the rock wool mat 2 is almost completely contained in the rock wool mat 2. Can be spread throughout. As a result, rainwater can be used sufficiently, and greening can be achieved without installing a water supply facility or simply installing a simple water supply facility. If the laminated thickness T is thicker than 15 cm, it becomes difficult to spread moisture to the upper part of the rock wool mat 2, and the moisture content in the vicinity of the end face 23 where the water-impermeable sheet 3 is not provided is lowered. End up. On the other hand, when the laminated thickness T is less than 5 cm, the moisture content is not uniformed and the water retention is not improved.

  In particular, in the greening material 12, as shown in FIG. 3, the adjacent greening mat 13 and the other greening mat 13 are different in that the water-impermeable sheet 3 of the single greening mat 13 is another greening. The mats 13 are laminated so as to be in contact with the end surface 23 on which the water-impermeable sheet 3 is not provided. Therefore, even if a plurality of the mats for greening 13 are laminated, Water retention is ensured.

  Further, in the greening mat 13 according to the present embodiment, the plurality of greening mats 13 are integrated by attaching the integrated sheet 4 to the other main surface 22 facing the main surface 21 that is a vegetation surface. . Thereby, the handleability is improved.

  Moreover, handling property and workability | operativity can be improved by storing the greening material 12 in the boxes 5 and 52, and making it into a panel. Thereby, when greening the outer wall of a building, the sound insulation wall of a highway, etc., it becomes only necessary to spread this greening panel 1, and greening with respect to a vertical wall surface or an inclined surface becomes easy.

  Further, the greening mat 13 according to the present embodiment includes the rock wool mat 2 and the water-impermeable sheet 3 for improving water retention, and thus is prepared for producing the greening mat 13. The number of members to be reduced can be reduced, and the production efficiency can be improved. Furthermore, since the vegetation surface is substantially parallel to the lamination direction of the random webs, the roots of the plants are easy to enter between the layers of the random webs, and the rooting is improved. As a result, the plant is firmly fixed to the rock wool mat.

  Although the invention made by the present inventor has been specifically described based on the embodiments, the present invention is not limited to the above-described embodiments, and various modifications can be made. For example, although the number of the greening mats 13 included in the greening material 12 is four in the above-described embodiment, any number may be selected.

  Further, the above-mentioned greening material 12 can be used alone, and the greening mat 13 can also be used alone.

  Examples of the present invention will be described below, but the present invention is not limited thereto.

First, a plurality of random webs mainly composed of rock wool were laminated to obtain a rock wool mat 2 having a density of 80 kg / m ³ . Next, the rock wool mat 2 was cut into a laminated thickness of 15 cm, a length of 60 cm, and a width of 5 cm. Then, a polyethylene sheet 3 (water-impermeable sheet) having a thickness of 15 μm was attached to one of the pair of end surfaces 23 and 24 in the laminating direction of the rock wool mat 2 to obtain a greening mat 13.

  Four greening mats 13 obtained as described above were prepared. Next, these four greening mats 13 are brought into contact with the end surface 23 of the one greening mat 13 on which the water-impermeable sheet 3 of the other greening mat 13 is not provided. Laminated. Next, the non-woven fabric 4 (integrated sheet) is integrated on the main surface 22 of the pair of main surfaces 21 and 22 which is not the vegetation surface, and the laminated thickness is 60 cm, the length is 60 cm, and the width is 5 cm. A greening material 12 was obtained.

  Further, the moss seeds are grown on the main surface 21 (vegetation surface) opposite to the main surface 22 to which the nonwoven fabric 4 (integrated sheet) of the greening material 12 obtained in this way is attached. It was made dense. Next, this is put into a container 5 (box body) made of stainless steel punching metal and having a hole, and the mesh mesh is covered with a metal mesh lid 52 (mesh) having a size of 20 mm × 20 mm. Thus, a greening panel 1 was obtained.
