Description

  The present invention relates to a roof / wall greening structure for cultivating moss on rooftops and rooftop floors of buildings and verandas.

  Conventionally, planting plants on the rooftop or veranda of buildings has been widely performed. However, the roof and the rooftop are strongly affected by the wind, so it is necessary to fix the planting container on the floor. In addition, it was necessary to water the plants in order to prevent the plants from withering when there was little rain. Furthermore, the rooftop and veranda had to be repaired and waterproofed again every predetermined year, and the planting container had to be removed. Moreover, when attaching to a roof, a wall surface, etc., the weight may become a problem.

Therefore, various plants for planting moss and the like have been proposed as satisfying these requirements. For example, as disclosed in Japanese Patent Application Laid-Open No. 2002-369617, etc., at least one of moss, seedlings, and seeds is spread on a base such as an unglazed block, and the upper surface is at least of paper, cloth, or net A greening promotion base material that is covered with any one or more and produced by spraying water has been proposed.
With such a configuration, any of moss, seedling, and seed can be integrated with the base, and the greening promotion base material can be easily manufactured. Further, it is possible to prevent the moss, seedlings and seeds from being blown off by the wind, and the moss, seedlings and seeds can be easily attached.

Moreover, as disclosed in Japanese Patent Application Laid-Open No. 2004-248631, a floor plate having water permeability is disposed in a shallow box-shaped storage body in which a large number of recesses are formed at the bottom, and soil is stored on the floor plate. However, a moss grown on this soil has been proposed.
With such a configuration, a predetermined part can be greened by simple construction, and moss can be grown with a small amount of water without using an irrigation apparatus. Also, by storing rainwater in the recesses, moss grows well even when the soil is dried by light rain.

Further, as disclosed in Japanese Patent Application Laid-Open No. 2005-160315, a rock wool mat is used as a medium, and a moss plant is grown on the surface and a mesh sheet is attached.
With such a configuration, it is possible to cultivate a durable moss mat while improving the efficiency of cultivation.

  However, the greening promotion base material disclosed in Japanese Patent Application Laid-Open No. 2002-369617 is intended to grow moss, seedlings and seeds on a base such as an unglazed block and is good for use on a slope such as a road. However, there is a fear that the weight increases when used on a rooftop or a roof. Moreover, in unglazed blocks, water retention is limited, and there is a problem whether moss can be grown without using a watering device.

  Moreover, in the tree planting device disclosed in Japanese Patent Application Laid-Open No. 2004-248631, when installed horizontally on a rooftop or a flat roof, moss can be grown without using an irrigation device, but it should be used on an inclined roof or wall surface. There was a problem that it was not possible. In addition, there is a problem that the soil is inclined when it is used while being inclined.

  In addition, in the greening device disclosed in Japanese Patent Application Laid-Open No. 2005-160315, when installed horizontally on a rooftop or a flat roof, the effect can be maximized, but when used on an inclined roof or wall surface. However, the moisture in the mat is inclined downward and there is a problem that it is difficult to grow moss uniformly on the surface of the mat. Moreover, when the mesh sheet is simply pasted, the moss may fall downward when used on a wall surface or the like.

  In order to achieve the above object, the device according to claim 1 is uniform on the surface of the rock wool, the water retaining material composed of a nonwoven fabric disposed on the back surface, the artificial medium composed of rock wool disposed on the front surface side, and the surface of the rock wool. The moss planted on the moss and a net covering at least the moss, the water retaining material, the medium, the moss and the net are sewed in parallel at a predetermined interval to form a plurality of reeds It is said.

  Further, in the invention according to claim 2, a plurality of lattice-like ridges are formed by sewing in a direction perpendicular to the recumbent ridges.

  Further, in the device according to claim 3, the net is made of synthetic resin fiber and has an opening of 2 mm square.

  In the invention according to claim 4, the water retention material is made of fibers obtained by regenerating a plastic bottle.

  Since this device has the above-described configuration, the following effects can be achieved.

  In the device according to claim 1, a water retention material comprising a nonwoven fabric disposed on the back surface, a medium composed of rock wool disposed on the front surface side, and moss uniformly planted on the surface of the rock wool, It consists of a net covering at least the moss, and a plurality of recumbent ridges are formed by sewing the water retaining material, the medium, the moss and the net in parallel at a predetermined interval, so that the roof / wall greening structure is inclined. Even when installed, the water absorbed by the water retention material is blocked by the side wall, preventing free fall due to gravity and maintaining the water retention power for a long time. In other words, the capillary phenomenon or the like inside the water retaining material slows down the fall of moisture due to gravity, so that the residence time can be lengthened and an irrigation device is unnecessary. In addition, since pruning and trimming are unnecessary, it is suitable for greening a place where people cannot enter, for example, a roof or a wall surface. Furthermore, since the net covers the surface of the moss, it can be prevented from being scattered or dropped by the wind or the like, and the survival of the medium can be promoted.

  Further, in the device according to claim 2, since the plurality of lattice-like ridges are formed by sewing in a direction perpendicular to the horizontal ridge, the water retention capacity of the water retention material can be further improved. In addition, the installation direction of the roof / wall greening structure can be freely selected vertically and horizontally, and the convenience in use is improved. Furthermore, by sewing in a lattice shape, it is possible to further slow down the moisture absorbed by the water retaining material due to gravity and to increase the residence time.

  Further, in the device according to claim 3, the net is made of synthetic resin fibers and has an opening of 2 mm square, so that the moss is prevented from scattering / falling and adapted to the thickness and length of the moss itself. The moss growth is not impaired. Further, when the moss grows, the net is covered with moss and cannot be seen from the outside, and is completely covered with green.

  Further, in the device according to claim 4, since the water retaining material is made of fibers obtained by regenerating a plastic bottle, recycling of resources can be promoted to make the product environmentally friendly.

  The present invention comprises a water retention material composed of a nonwoven fabric, an artificial medium composed of rock wool disposed on the surface side, moss uniformly planted on the surface of rock wool, and at least a net covering the moss, A plurality of recumbent ridges are formed by stitching in parallel at a predetermined interval through the wood, medium, moss and net, so that the residence time of absorbed moisture can be lengthened and the roof that can achieve good growth of moss A wall greening structure was realized.

  Hereinafter, the present invention will be described in detail with reference to the drawings showing an embodiment. 1 is a perspective view showing an example of a roof / wall greening structure according to the present invention, FIG. 2 is an exploded perspective view showing the roof / wall greening structure according to the present invention, and FIG. 3 is a cross-sectional view taken along line AA in FIG. FIG. Here, the roof / wall greening structure 10 is uniformly planted on the surface of the water retaining material 11 made of nonwoven fabric disposed on the back surface, the culture medium 12 composed of rock wool disposed on the front surface side, and the rock wool. And a net 14 covering at least the top of the snag 13 and passing through the water retaining material 11, the medium 12, the snag 13 and the net 14, and stitching them in parallel at a predetermined interval to form a plurality of reeds 15. Formed.

  The water retaining material 11 can be made of recycled fiber made from recycled PET (Poly Ethylene Terephthalate). That is, after a used PET bottle is finely pulverized, it is dissolved again and regenerated into polyester fiber. The water retaining material 11 holds the predetermined thickness and elasticity by laminating recycled fibers in a nonwoven fabric shape. For example, the thickness is about 15 to 25 mm.

  The medium 12 is made of inorganic rock wool and is suitable for growing moss and the like. It can also be reused. About 10-30 mm is sufficient for the thickness of the culture medium 12. Snagoke 13 is seeded on the surface of the culture medium 12 in advance.

  The thread | yarn used for the net | network 14 consists of synthetic resin fibers, such as a polypropylene and a transparent acrylic, and uses a 290-400 denier thing. Further, the mesh size (size of the opening) can be appropriately selected according to the size of the moss individual. The net can prevent snags from being dissipated by wind or the like, and can enhance the survival of the medium 12. In the case of snago, an opening of about 2 mm square is suitable, and when the snag grows and grows from the opening, the net becomes invisible due to moss. Moreover, the effect that the adhesion degree of the net | network 14 and the snag 13 is increased by sewing the whole can be show | played.

In addition, the interval between the side ridges 15 formed by sewing in parallel at a predetermined interval through the water retaining material 11, the culture medium 12, the snag 13 and the net 14 is about 8 cm. The density of the water retaining material 11 is improved by sewing, and the retained water can be prevented from flowing out due to gravity. The roof / wall greening structure 10 is a square or a rectangle, and its size is 500 × 500 mm, 500 × 1000 mm, 1000 × 1000 mm, or the like.
Since the water-retaining material 11, the culture medium 12, and the net 14 made of synthetic resin are used in this embodiment, they are strong against deterioration due to corrosion and have durability.

  A method of using the roof / wall greening structure 10 according to the present invention configured as described above will be described. First, when used for a roof as shown in FIG. 6, the horizontal bar 15 formed by sewing is arranged so as to be perpendicular to the inclination direction of the roof and attached to the roof. When the roof / wall greening structure 10 is arranged in this manner, rainwater flows in a direction perpendicular to the inclination direction (lateral direction) along the reeds 15 and the residence time can be lengthened. Therefore, even with a small amount of water, sufficient irrigation can be achieved for snails and the like.

  In the case of building rooftops and flat roofs, the roof / wall greening structure is installed as it is. In the case of a folded-plate roof, a metal frame is laid on the ground, and a roof / wall greening structure is laid from above.

  Moreover, since the surface of the snago 13 encapsulated in the culture medium 12 is covered with the net 14, it can be prevented from scattering and dropping, and it conforms to the thickness and length of the snago itself and impairs the growth of snago. There is no.

  Next, the manufacturing method of the roof and wall surface greening structure 10 is demonstrated. As shown in FIG. 2, first, the water retaining material 11 cut into a square shape and the net 14 cut larger than the water retaining material 11 are sewn together in the vicinity K of one side. Next, the culture medium 12 cut almost equally to the water retention material is superimposed on the water retention material 11. At this time, snago 13 is engrafted on the surface of the culture medium 12. Further, a seam allowance L is marked on the back surface of the water retaining material 11 at equal intervals.

  Snagoke 13 is wrapped with a net 14 having one side fixed to the back surface of the water retaining material 11. The net 14 enclosing the snago 13 is wound around the back surface of the water retaining material 11 and sewn. Further, the water retaining material 11, the culture medium 12, the snail 13 and the net 14 are integrated by sequentially sewing along the seam allowance L marked on the back surface of the water retaining material 11, and the roof / wall surface greening structure 10 having the horizontal reed 15 is formed. Can be manufactured.

  Also, as shown in FIG. 4, the roof / wall greening structure 10 configured as described above is set on a frame 16 made of aluminum or the like, and a metal grid 16-1 is covered from above. The grid 16-1 is made by welding an iron wire in a grid and coating the surface with polypropylene powder 16-2. Moreover, the grid 16-1 may be a stainless steel wire mesh. The frame 16 has a box shape with an open upper end, and has a depth substantially equal to the thickness of the roof / wall greening structure 10. The frame body 16 may be made of a box-type or angle-type metal or synthetic resin.

  In the case of such a configuration, the rigidity is increased by attaching the frame body 16, and the installation work on the roof or the wall surface becomes easy. Moreover, since rain water accumulates in the frame 16, the water retention effect of the water retention material 11 can be improved.

  FIG. 5 is a perspective view showing another modification of the roof / wall greening structure of the present invention. In the present embodiment, the roof / wall greening structure 20 is sewn in a direction perpendicular to the reed 15 and a plurality of lattice-shaped reeds 18 are formed by the seams 17. The width of the seam 17 is about 8 cm. By forming seams in a lattice shape, the water retention capacity of the water retention material 11 and the culture medium 12 is increased, and rainwater can be retained for a long time even when installed on an inclined roof or wall surface.

  When comprised as mentioned above, since the several grid | lattice-like ridges 18 are formed in the roof and wall surface greening structure 20, it can attach freely vertically and horizontally, without restrict | limiting the installation direction of a greening structure. Further, the hardness of the water retaining material is proportional to the specific gravity, but by sewing, the hardness of the water retaining material increases and the strength of the waist increases. Therefore, handling becomes easy and workability for installation is improved.

  FIG. 6 is an explanatory diagram showing a case where the roof / wall greening structure of the present invention is used for a roof. In this embodiment, the roof / wall greening structure 10 is installed on the roof 19. The roof / wall greening structure 10 may be installed on the entire surface of the roof 19 or a part thereof. When a power generation panel or water heater is attached to the roof, it can be installed freely except for that part. In this way, in the present invention, snails are used as a greening plant, so that they can be grown only with rainwater, and no special irrigation device is required. In addition, fertilization and pruning work are unnecessary, and labor saving management is possible.

FIG. 7 is an explanatory diagram showing a case where the roof / wall greening structure of the present invention is used for a building wall.
The roof / wall greening structure 10 may be installed on the entire surface of the wall surface of the building 20 or a part thereof. When there is a window, it can be installed freely except for that part. In this way, in the present invention, snails are used as a greening plant, so that they can be grown only in rain water. Even in places where it is difficult for people on the wall of the building to enter, greening is possible because fertilization and pruning work are not required.
