Description

  The present invention relates to a bottom structure of a planting part for greening a veranda, a rooftop, a roof, a wall surface and the like of a building.

  In order to cope with the heat island phenomenon in urban areas, so-called greening of buildings is being promoted to green the verandas, rooftops, roofs, walls, etc. of buildings. Plants are expected to suppress the heat island phenomenon due to the cooling effect of the atmosphere due to its transpiration, and also have an air purification action such as adsorption of pollutants. In addition, the rainwater storage effect can be expected by the soil where the plant is planted, and it can prevent drastic inflow of rainwater to the sewage main, so it can greatly contribute to the suppression of urban flooding. It also greatly contributes to improving the cityscape and landscape (landscape design including landscaping and horticulture techniques). Plants can attract wild birds and insects, and are expected to have a significant effect on the revival of the urban ecosphere. Even the roofs in urban areas are not all high-rise buildings, and the roof area of a detached house occupies an overwhelmingly large area. Therefore, realizing the greening of these detached houses greatly contributes to the mitigation of the heat island phenomenon.

  On the other hand, a combination sheet steel sheet for waterproofing a connecting portion between waterproof sheets laid on a bent portion of a structure is disclosed in Japanese Patent No. 2798213 (Patent Document 1) and Japanese Patent No. 2733509 (Patent Document 2). .

  However, there are many problems to be solved when trying to plant a detached house. One of them is the problem of maintaining the wet state of the soil. That is, for example, in a rooftop green area formed in a building, it is impossible to form a soil layer with an unlimited thickness in terms of the allowable load capacity of the building, and the thickness of the soil layer must be reduced.

  For this reason, there exists a problem that soil is easy to dry and lack of moisture has a bad influence on growth of a plant. Because it was greatly affected by sunshine and rain, it was difficult to manage, and planting was likely to wither and root rot was likely to occur.

  In conventional greening of buildings, a fixed-size base such as a planter or pallet is generally used, and as a result, it was difficult to realize subtle dimensional design and curved surface design design. In particular, there was a problem that the degree of freedom corresponding to the undulations in the height direction and planar curves could not be realized. In addition, there is a water retention space in the lower layer, but floor finishing materials are always directly exposed to veranda and rooftop flooring materials that contain soil, microorganisms, fertilizers, pesticides, etc. Degradation is promoted.

  In addition, when irrigated or raining, water containing soil, nutrients, microorganisms, fertilizers, etc. flows out to parts other than greening, and soils and deteriorates floor finishing materials on the veranda and rooftops. Therefore, it was not a good environment for the building.

  Overflowing moss is generated by running down the surplus water, and it is dried, and the soil and adverse components accumulate by repeating the cycle of running down the surplus water, and moss is also generated in flooring materials other than the greening part. give. In addition, aesthetic problems occur and cleaning is troublesome.

  In the conventional pallet-type foundation formation, the foundation itself is heavy as a result, a large soil thickness cannot be secured, and a large water retention amount cannot be secured. In addition, since the conventional greening of buildings is a lot of work that has to be made on site, it takes time. In addition, there has been a problem that the cost becomes enormous, such as the need to remove soil or planting or re-construction when replacing the floor finishing material in the greening part.

  In addition, there is a problem that the water level of the water retention layer of the planting part is biased due to the water gradient of the rooftop, and the reaction force is difficult to take in the shallow soil layer, so the trees tend to fall down due to strong winds, and anchors that support the trees from the building frame are erected It was hard at the level of detached houses. In addition, there was a problem that rainwater or water sprinkled around the planting part and was not drained, which impaired the beauty.

  This invention solves the said subject, The place made into the objective can aim at the weight reduction and design freedom of the bottom part of a planting part, and the floor finishing material of the floor surface in which a planting part is provided is provided. Protects from water containing soil, nutrients, microorganisms, fertilizers, etc., and can guide surplus water to drainage facilities, makes the water level of the water retention layer uniform regardless of the floor slope, is easy to replace, and depends on the weather It is possible to maintain the optimum amount of water at a low cost without any problems, eliminate the pool around the planting part, and provide a partition member that can easily fix the tree and the bottom part of the planting part using this.

FIG.

  1-4, 1 is a partition member which partitions the peripheral part of a planting part (planting green areas, such as a flower, a lawn, a tree, a fruit tree), and the long steel plate 2 of L-shaped cross section, A belt-shaped waterproof sheet 3 that is water-tightly bonded to the bottom of the support piece 2b of the long steel plate 2 and that is extended with a predetermined width from the bottom edge of the support piece 2b in the short direction. . The long steel plate 2 withstands earth pressure, is waterproof, and can be bent or bent, and is connected to the partition piece 2a substantially orthogonally to stand the partition piece 2a upright. And a support piece 2b that can be supported in a state.

  The partition piece 2a of the long steel plate 2 can be bent or bent, and the long steel plate 2 is bent into a desired shape by partially cutting the support piece 2b of the portion to be bent or bent. Or it can be folded. Then, depending on the shape of the support piece 2b of the long steel plate 2 curved or bent into a linear shape or a desired shape, the support piece 2b has a predetermined width from the bottom edge in the short direction to both sides or one side. The belt-shaped waterproof sheet 3 is created with the extended shape, and the belt-shaped waterproof sheet 3 is water-tightly bonded to the bottom of the support piece 2b with an adhesive or the like.

  For example, a linear partition member 1a as shown in FIG. 3 (a) is used in the straight part of the planting part, and the right-angled corner part of the planting part is bent at a right angle as shown in FIG. 3 (b). The partition member 1b is used, and the partition member 1c as shown in FIG.

  And according to the external shape of the planting part designed on the floor finishing material 5 such as a floor waterproof sheet laid on the veranda of the building where the planting part is provided, the rooftop, or the roof, the partition member 1a , 1b, 1c are appropriately selected and continued to surround the periphery of the planting part. Adjacent partition members 1a, 1b, and 1c are joined to each boundary portion in a watertight manner by means of an adhesive or heat welding across the joining waterproof sheet 10. Here, the adhesive includes a case where the welding agent is not volatilized and remains after the sheet is melted for a moment with the welding agent.

  At that time, as shown in FIG. 7, a long nonwoven fabric (for example, PP) constituting a water conduit between the floor finishing material 5 and the strip-shaped waterproof sheet 3 of the partition member 1 along the gradient direction of the floor surface. (Poly Propylene (polypropylene) processed plate material) 6 is installed across the lower ends of the planting part, and the bypass forming sheet 28 is placed so as to cover the upper part of the nonwoven fabric 6. The both sides of the bypass forming sheet 28 along the nonwoven fabric 6 are water-tightly bonded to the floor covering material 5 by an adhesive or heat welding. As a result, the rainwater 25 collected on the upstream side in the gradient direction of the floor surface outside the peripheral portion surrounding the partition member 1 in a continuous manner is drained through this water conduit, and the water pool is eliminated to maintain the beauty. I can do it.

  Since the partition piece 2a can be easily bent or curved by cutting off a part of the support piece 2b of the partition member 1, it is arranged freely according to the planar curve of the designed planting part. I can do it. Moreover, the some partition member 1 can be connected according to the raising / lowering of the height direction of a floor surface. Moreover, since it is a simple structure, the bottom part structure of a planting part can be reduced in weight, and the thickness of the soil layer 19 or the water retention layer 18 can be increased correspondingly. Thereby, water retention performance can be improved, soil drying can be prevented, and the types of planted plants 11 to be planted can be increased and greening from the seeds can be enjoyed. In addition, because it is simple and lightweight, it can be easily replaced.

  A protective waterproof sheet 9 is laid on the upper surface of the floor finishing material 5 on the floor surface inside the peripheral portion surrounding the partition members 1 in a continuous manner and on which the planting part on which the partition members 1 are placed is provided. The divided protective waterproof sheets 9 are overlapped on the upper portions on both sides along the nonwoven fabric 6 covered with the bypass forming sheet 28 and bonded in a watertight manner with an adhesive or heat welding. Is done.

  Thereby, it is possible to avoid the overlapping of sheets as much as possible, and to reduce the undulation height around the water conduit, and in the event of an abnormality such as clogging of the water conduit, the overlapping portion can be peeled off for easy maintenance. The protective waterproof sheet 9 can be continuously stacked on the upper part of the bypass forming sheet 28 without being divided.

  The protective waterproof sheet 9 is a sheet having functions of protecting the floor finish 5 and preventing intrusion of roots of plants (root prevention), but also includes a sheet in which sheets having respective functions are overlapped.

Is used, the protective waterproof sheet 9 is overlapped on the upper surface of the belt-shaped waterproof sheet 3 and is watertightly bonded by an adhesive or heat welding.

  Further, as shown in FIG. 5 (b), the waterproof sheet for bonding 10 is straddled across the protective waterproof sheet 9 and the support piece 2b of the partition member 1 overlapped on the upper surface of the belt-shaped waterproof sheet 3 of FIG. 5 (a). It is also possible to bond watertightly by an adhesive or heat welding.

  Further, as shown in FIG. 5 (c), a belt-shaped waterproof sheet 3 extending from the bottom edge in the short direction of the support piece 2b of the partition member 1 to the outside of the partition piece 2a with a predetermined width is attached to the support piece 2b. When the partition member 1 bonded to the bottom is used, the protective waterproof sheet 9 is overlapped on the upper surface of the support piece 2b of the partition member 1 and is watertightly bonded by an adhesive or heat welding. Then, the protective waterproof sheet 9 is water-tightly bonded to the upper surface of the floor covering material 5 by an adhesive or heat welding.

  The protective waterproof sheet 9 is overlapped on the floor covering material 5 in a watertight manner so as to overlap the strip-shaped waterproof sheet 3 extended from the bottom edge in the short direction of the support piece 2b of the partition member 1 or the support piece 2b. The floor finishing material 5 on the floor surface where the planting part is provided can be reliably protected by the protective waterproof sheet 9 and the strip-shaped waterproof sheet 3.

  Thereby, since the floor finishing material 5 of the floor surface in which a planting part is provided is not exposed to the water containing a soil, a nutrient, microorganisms, a fertilizer, etc., it can prevent dirt and deterioration. In addition, since the protective waterproof sheet 9 is capable of following the undulations of the floor surface on which the planting part is provided, the bottom structure of the planting part that can flexibly cope with the undulations and planar curves in the height direction of the floor surface. It can be realized. Further, the protective waterproof sheet 9 can prevent the root of the planted plant 11 from entering the building.

  Moreover, when replacing with the new floor finishing material 5 as a response | compatibility at the time of deterioration of the floor finishing material 5 around the planting part, for example, as shown in FIG. A portion of the belt-shaped waterproof sheet 3 that overlaps the material 5 is cut off from the curb member 15 while leaving the adhesive portion 27, and both the belt-shaped waterproof sheet 3 and the floor finish material 5 are cut to remove the deteriorated floor finish material 5a. .

  And after cutting, as shown in FIG.8 (c), a new floor finish 5b is made to overlap with the floor finish 5 which has not progressed the deterioration left in the peripheral part of a planting part, and adhesive or heat The floor finish 5 is bonded by water-tight adhesion by welding, and the protruding portion of the belt-shaped waterproof sheet 3 is overlapped with the new floor finish 5b and water-tightly adhered by an adhesive or heat welding. Replacement can be performed easily. Thereby, removal of a planting part and re-construction can be avoided.

  Further, as another method of replacing the new floor finishing material 5, as shown in FIG. 9A, it protrudes from the curb member 15 of the belt-shaped waterproof sheet 3 overlapped with the floor finishing material 5 on the floor surface. As shown in FIG. 9 (b), the portion is cut leaving the adhesive portion 27, and a new floor finishing material 5b is laid on top of the deteriorated floor finishing material 5a, as shown in FIG. 9 (c). In addition, a new floor finish 5b is overlapped on a portion of the peripheral portion of the planting portion where the deterioration of the floor finish 5 has not progressed, and water-tightly bonded by an adhesive or heat welding, and the new floor finish The floor finishing material 5 can be easily replaced by overlapping the protruding portion of the strip-shaped waterproof sheet 3 on the material 5b and watertightly adhering it with an adhesive or heat welding.

  The protruding dimension of the band-shaped waterproof sheet 3 from the curb member 15 can secure the bonding margin of the band-shaped waterproof sheet 3 and the bonding margin of the new floor finishing material 5b and the existing floor finishing material 5 (for example, 10 cm width). Degree).

  FIG. 4 shows an example of the intermediate partition member 7 installed at a predetermined interval corresponding to the slope of the floor surface on which the planting part is provided on the protective waterproof sheet 9 inside the peripheral part surrounding the partition member 1 in a continuous manner. It is an example. The partition member 7 shown in FIG. 4 (a) is resistant to earth pressure and has a waterproof partition piece 8a and is connected to the partition piece 8a substantially orthogonally, and supports the partition piece 8a in an upright state. It consists of a long steel plate with an L-shaped cross section having a support piece 8b to be obtained.

  For example, a linear partition member 7a as shown in FIG. 4 (a) is used for a linear partition, and a T shape as shown in FIG. 4 (b) is used for a T partition. In the partition which uses the shape of the partition member 7b and divides into a cross shape, a cross-shaped partition member 7c as shown in FIG. 4C can be used.

  Further, by cutting away a part of the support piece 8b of the middle partition member 7a shown in FIG. 4A, the partition piece 8a can be easily bent or bent, and is bent or bent into a desired shape. A partition member 7 can also be used.

  And according to the partition design of the planting part, these inner partition members 7a, 7b, 7c are appropriately selected and made continuous, and the inside of the peripheral part of the planting part surrounded by a plurality of partition members 1 is partitioned. To do. The adjacent middle partition members 7a, 7b, 7c and the partition member 1 are joined to each boundary portion in a watertight manner by an adhesive or heat welding across the joining waterproof sheet 10.

  A predetermined height position of the partition piece 2a of the partition member 1 and the partition piece 8a of the middle partition member 7 is surrounded by the partition members 1 and 7, and discharges excess water 26 inside each partitioned cell, A through hole 4 serving as an opening serving as a fixing portion for fixing the locking member 12 that restrains the planted object 11 to be planted is formed. Thereby, since the total weight of the bottom structure of the planting part acts on the reaction force in the pulling direction of the planted object 11, it is possible to reliably prevent the planted object 11 from falling or scattering.

  The through holes 4 of the partition member 1 and the middle partition member 7 are also used as a fixing portion for fixing the locking member 12 that restrains the planted object 11. A PP band made of polypropylene resin or the like can be used as the locking member 12, and the other loop portion whose both ends are locked to the planted object 11 is inserted into the through hole 4 and fixed by a comb-like stopper.

  Thereby, as shown in FIG. 2, the water level inside each cell partitioned by the partition member 1 and the middle partition member 7 can be made uniform irrespective of the gradient of the floor surface on which the planting part is provided. Further, excess water 26 in each cell is sequentially discharged from the upstream side to the downstream side in the gradient direction of the floor surface through the through hole 4 that is an opening provided in the inner partition member 7 so that there is no excess or deficiency in each cell. Water goes around. Moreover, the water level suitable for a plant of a different kind for every cell can be set suitably by setting opening height suitably in the tolerance | permissible_range of a building structure proof stress. As an example of the cell design, it is preferable that the cell size is designed to be 1400 mm × 1400 mm for a water gradient of about 1/100.

Thereby, it can adjust to the amount of water retention matched with the allowable load of the building. In addition, root rot due to excessive water supply of the plant 11 can be prevented.

  Moreover, it is drained outside the planting part through a rectangular long hole provided above the through hole 4 for fixing the top side of the partition piece 2a and the locking member 12 for restraining the planted object 11. As a result, water containing soil, nutrients, microorganisms, fertilizer, etc. does not overflow into the floor finishing material 5 on the floor surface even outside the planting part, and the drainage facility comprising the curb member 15 Since it is guided and drained, dirt and deterioration can be prevented, and aesthetics can be maintained.

As shown in FIG. 2 and FIG. 6, inside the peripheral portion surrounding the partition member 1 in a continuous manner, or inside each cell partitioned by the partition member 1 and the partition member 7, or between the partition members 7. A water retention layer 18 that retains water , a soil layer 19 that is laid on top of the water retention layer 18, a three-dimensional structure 20 disposed in the soil layer 19, and a portion that covers and covers the three-dimensional structure 20 A scavenging water sheet 21 arranged below the water surface of the water retention layer 18 is installed.

  Since the three-dimensional structure 20 covered with the pumping water sheet 21 is arranged in the soil layer 19 and a part of the water pumping sheet 21 reaches below the water surface of the water retention layer 18, a part of the water pumping sheet 21 is always water. The water in the water-retaining layer 18 can be pumped up by capillary action. This water can be supplied to the soil around the three-dimensional structure 20 to wet the soil.

  In particular, by arranging a plurality of the three-dimensional structures 20 at a predetermined pitch on the soil layer 19, the water pumped up by the scooping sheet 21 covering the three-dimensional structures 20 is used by the scooping water sheet 21 covering the adjacent three-dimensional structures 20. It is connected with the pumped water, raises the wet boundary surface between the adjacent three-dimensional structures 20, and forms a wet state at a higher level than the highest position of the pumped water sheet 21 covering the three-dimensional structure 20. Can be moistened.

  For this reason, it becomes possible to use the water of the water retention layer 18 effectively, and it is possible to realize a stable water supply by reducing useless watering to the soil. In particular, since soil can be moistened to a high position, cultivation from seeds that has been difficult in the past and cultivation of seedlings with short roots can be easily realized.

  The partition piece 2a of the partition member 1 or the partition piece 8a of the middle partition member 7 is provided with a scale indicating the limit height of the embankment on the surface thereof, or the partition piece 2a of the partition member 1 or the partition piece 8a of the middle partition member 7 The height is set to the limit height of the embankment.

  Thereby, the load can be easily managed by performing the embankment to the height of the partition piece 2a of the partition member 1 or the partition piece 8a of the middle partition member 7. The load can also be managed by embankment up to the scale provided on the partition piece 2a of the partition member 1 or the partition piece 8a of the middle partition member 7. When the middle partition member 7 is embedded in the soil layer 19, a scale indicating the limit height of the embankment is provided on the surface of the partition piece 2a of the partition member 1.

  The water-retaining layer 18 is made of a plastic resin fiber having high hardness and durability that is entangled in a plate shape to ensure a sufficient water-retaining space and has compression resistance and corrosion resistance. It is possible to work from above the soil. The protective waterproof sheet 9 provided on the lower side of the water-retaining layer 18 prevents the water stored in the water-retaining layer 18 from leaking onto the floor finish 5 and the root of the plant 11 planted in the soil layer 19 is the floor. It prevents the finishing material 5 and the building from being damaged.

  The water retention layer 18 can store water for a predetermined number of days required by the target planting part. The depth of the water retention layer 18 is designed in consideration of the kind of the plant 11 cultivated in the planting part, the water retention performance of the soil constituting the soil layer 19 and the thickness of the soil layer 19.

  The water level of the water retention layer 18 or the water content of the soil layer 19 is inside the peripheral part of the planting part surrounded by a plurality of partition members 1 or inside each cell partitioned by the partition member 1 and the intermediate partition member 7. The water retention amount detecting means 24 for detecting the water content, and the inside of the peripheral portion of the planting part surrounded by a plurality of partition members 1 according to the water retention amount detected by the water retention amount detection means 24, or the partition member 1 and the partition A water supply means 22 for supplying water into each cell partitioned by the member 7 is provided.

  The water retention amount detection means 24 of the present embodiment uses a water level sensor that detects a water level when a plurality of electrodes having different lengths are installed in the water retention layer 18 and a current flows through the water in the water retention layer 18. ing. Further, the water supply means 22 is configured to open and close the electromagnetic valve according to the water level information detected by the water retention amount detection means 24 comprising a water level sensor.

  Thereby, the moist state of soil can be stabilized and it can contribute to the cultivation of the planted material 11. Moreover, since there is no excessive drainage, the outflow of soil can be reduced. In addition, water is retained with rain water as much as possible, and excess is sequentially discharged from each cell through the through hole 4 and drained from the drain pipe 13 provided in the partition member 1 to the drain groove 16a of the curb member 15, and the water level is predetermined. The running cost can be reduced because water can be automatically supplied only when the level is below the level.

  In this way, by limiting the amount of water that can be retained in the water retention layer 18, it becomes possible to maintain a stable load without exceeding the load that the building should bear, and to quickly discharge the overflowed water. There is no adverse effect on the floor covering 5 and the building.

  The nature of the soil that constitutes the soil layer 19 is not particularly limited, and garden soil with fine particles, coarse sand with particles, or artificial lightweight soil with reduced weight can be used. Artificial lightweight soil can be formed by crushing ALC panels recovered at the production site of lightweight cellular concrete (ALC) panels and recovered from renovation, and has a wide range of particle sizes, moderate water retention and drainage In addition, since it has air permeability and has a small specific gravity and is extremely lightweight, it is most suitable for a planting part installed on a veranda of a building, a rooftop, or a floor of a roof. Even such an artificial lightweight soil has an appropriate water retention ability, and can retain nutrients given from the outside.

  In order to maintain the water retention performance of the water retention layer 18, it is preferable that the soil constituting the soil layer 19 disposed above the water retention layer 18 does not move to the water retention layer 18, so that the water retention layer 18 and the soil layer 19 A water permeable layer 23 is provided therebetween. The water permeable layer 23 has a function of permeating water and preventing passage of granular soil, and a function of preventing the roots of the plant 11 from invading the water retention layer 18, using synthetic resin fibers. Nonwoven fabrics can be used.

Steric structure 20 of this embodiment has been constituted by quadrangular prism made of a synthetic resin foam having a rigidity and stability to withstand the load when working resting human soil layer 19, and further Various shapes of three-dimensional structures that can secure a height for lifting the scooping water sheet 21 to a high position of the soil layer 19 can be applied. If the interior of the three-dimensional structure 20 is made hollow, the water retention amount of the water retention layer 18 can be increased, and the load can be reduced.
