DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sloped roof planting construction applied to greening a sloped roof such as a house.

[0002]

2. Description of the Related Art Conventionally, it is generally known that, in order to green a flat surface such as the roof of a building, planting is performed simultaneously with waterproofing on the waterproofed surface. Needless to say, the above-mentioned known technology cannot be applied to the planting work for performing the planting. Planting works for greening sloped roofs are performed in Europe, particularly Germany. The construction method is to lay a drain layer consisting of a drain mat on the entire waterproof construction surface of the sloped roof, provide a filter layer consisting of a fiber sheet on its upper surface, and provide an embankment layer of the desired thickness on the entire upper surface. Then, a large U-shaped frame is formed with a frame plate of a predetermined height from the edge of the eave around the edge to the edge of the kerb on both sides, and the entire upper surface of the filter layer is formed in the large frame. The soil is filled and deposited, and an embankment layer is formed to fill the height of the surrounding frame to complete the planting work.On the upper surface of the embankment layer, flowers and turf are grown and greened. is there.

[0003]

In the above-mentioned conventional planting body with a sloped roof, rainwater that has passed through the embankment layer during rainfall is prevented from passing through soil particles by the filter layer, and the excess rainwater Is allowed to pass through, drains to the drain layer below it, flows down the roof slope, is drained to the outside, drainage measures against rainfall are taken, but when the rainfall is large temporarily, In places where annual rainfall is relatively large, such as Japan, the embankment layer containing excess rainwater becomes flexible, and it tends to gradually move to the eaves front along the slope of the sloped roof with its weight. However, there is a disadvantage that inconveniences such as collapse of the embankment layer and runoff cannot be avoided. Therefore, even if it is applied to an area with a large amount of rainfall, the waterproofness is good and the drainage is well performed over the entire sloped roof over a long period after the planting work,
It is desired that the planting work always be kept stable and good without collapse and erosion of the embankment layer.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and provides a planting construction body having a sloped roof which maintains excellent waterproofness and drainage for a long period of time and has good stability. A waterproof sheet is stuck and laid on the entire surface of the sloped roof base material, and at least one drain hole is provided on the laid surface of the waterproof sheet along the edge of the eaves over at least the entire length thereof. A plurality of long drainage plates are erected in parallel in the gradient direction at desired intervals to divide the space above the waterproof sheet laying surface into a plurality of longitudinal spaces in the gradient direction. Of a plurality of rows of longitudinal spaces, at least one of which is in contact with both ends of these draining long plates and along the edges of the drainage long plates and over substantially the entire length thereof. Erecting a long plate for the above-mentioned longitudinal division of the plurality of rows Between formed longitudinally encircling space,
In each of the long surrounding spaces, a water-permeable root-proof sheet is superposed on the entire inner surface of the long drainage plate, and furthermore, a linear bend in the three-dimensional direction is formed in the long surrounding space of each row. A three-dimensional mesh sheet formed by forming three-dimensional large continuous pores is loaded to a desired height position lower than the height of the long drainage plate, and the three-dimensional continuous pores of the three-dimensional mesh sheet are loaded. A plurality of rows of planting construction sections are constructed by filling the soil with the soil and embedding the soil so as to form a covering layer having a desired thickness on the upper surface of the filling layer.

[0005]

According to the present invention, the waterproofness of the sloped roof base is maintained by the waterproof sheet laid on the entire surface to be processed. On the upper surface, a plurality of rows of planting construction sections divided by a plurality of rows of drainage plates perpendicular to the gradient direction were constructed, so that the total weight of soil on the entire sloped roof was reduced in each section. Since the work is shared by the works, a relatively small amount of a light soil layer is stably maintained in each work. In addition, through the innumerable drain holes of the long drainage plate that is the boundary of each section, the excess rainwater generated during rainfall in each section flows down from the upstream side to the downstream side along the slope, and finally. Since the water is discharged to the outside from the eaves edge, the drainage in each section is maintained well. Also,
Since the water-permeable root-prevention sheet is polymerized on the inner surface of the drainage long plate of each section, it is closed by thin roots such as flowers and turf planted with numerous holes in the drainage long plate. Can be prevented and its drainage can be ensured. In addition, the three-dimensional net-like sheet loaded in each planting section can prevent the soil filled in the three-dimensional holes from moving, and can stably hold the soil. The embankment of the covering soil layer is suitable for sowing such as flowers and vegetation such as seedlings.

In the case where the above-mentioned planting construction section of the present invention is provided on each of the work surfaces of the pair of front and rear sloped roof base materials which are arranged with the edges of the building being joined together, A ridge waterproof sheet is attached and laid across the opposing edges of the ridge and over substantially the entire length thereof, and the ridge formed between the front and rear closing long plates on each side on both sides of the upper surface. A ridge-blocking plate for closing the gap is erected, and the planting construction body of the present invention is configured to extend over the inside of the longest enclosed space in the uppermost row of the sloped roof before and after the ridge. Is preferred.

[0007] The long plate for drainage and the long plate for closing are
It is possible to use an extremely long one that extends over the entire length of the eaves tip edge or, if possible, the entire edge, but prepare a plurality of relatively short ones from the viewpoint of ease of handling and work in construction work. It is preferable to stand upright in a row while overlapping or touching. The erecting is generally performed by the cross section L
Using a long shaped plate of T-shape or T-shape, in the long bottom plate, lay it on the surface of the waterproof sheet and nail it to the surface of the base material. It can be prepared as an elongate plate for drainage having a hole or an elongate plate for closing, respectively. More specifically, in the case of a long formed plate having an L-shaped cross section, adjacent ends are overlapped or abutted, and in the case of a long formed plate having a T-shaped cross section, adjacent edges are formed. Are preferably arranged in a line in a row.

When an asphalt waterproofing sheet is used as the waterproofing sheet, at least the surface facing the surface of the work is made to be an adhesive surface, and is adhered and laid. Any of those having an adhesive surface or those having an adhesive surface can be used. If a waterproof sheet with an adhesive surface on the top is also laid down, use a plurality of long bottom plates with long L-shaped cross sections for drainage.
By sticking and covering the entire adhesive surface of the laid waterproof sheet with the respective long bottom plates successively in the direction of the slope of the roof, fire protection can be imparted, and at the same time, subsequent construction work On the other hand, the long bottom plate of the long formed plate in each row is useful because it naturally helps to define the bottom surface of the long section space of each row.

[0009] The heights of the drainage long plate and the closing long plate define the height of the space formed by them, and can be determined according to the thickness of the embankment layer to be planned.

In addition, as a waterproof sheet, on both side edges thereof,
When leaving a part to be overlapped and forming a release paper with cut lines along its both side edges on the inside temporarily attached to at least the adhesive surface on the upper surface, it is adjacent to the waterproof sheet. It is possible to facilitate the work of waterproofing construction in which both side edges are superposed and adhered.

The water-permeable root-prevention sheet is made of a water-resistant and germ-resistant woven or non-woven fabric, has a water permeability specified in JIS A 1218 of 10 ^-4 cm / sec or more, and has a mesh size of 30 or more.
When the thickness is less than μm, it does not penetrate the roots of flowers and the like, and blocks the passage of soil particles, while allowing the permeation of water. Such a woven or nonwoven fabric is water-resistant when made of synthetic resin fibers or its filaments,
Further, it is not decomposed by microorganisms in the soil, and is suitable for long-term use and is preferable. In particular, it is preferable to use a woven fabric woven from synthetic fiber filaments.

[0012] In the long surrounding space of each row, a water-permeable root-preventing sheet is superposed on the inner surface of the long draining plate opposed thereto. The width of the root sheet is wide from the bottom of the long surrounding space to the height of the long drainage plate rising on both sides thereof,
When this is laid on the bottom surface of the surrounding space, both side surfaces are naturally bent and rise up by themselves, and each is overlapped on the inner surface of the corresponding rising drainage long plate, thereby facilitating the polymerization work. it can. In this case, the water-permeable root-proof sheet laid on the bottom surface also prevents the roots of the plant from passing through the eyes of the sheet and helps protect the waterproof sheet on the lower surface from damage by the root. In general, it is preferable to use a roll-shaped elongate sheet as the water-permeable root-prevention sheet. When the sheet is unwound in the length direction on the bottom surface of the surrounding space and is laid, the opposed draining long plate is used. Can be polymerized over the entire length. In this case, when the roll-shaped material is lost in the middle and a new roll-shaped material is laid, the edges are appropriately overlapped, and the edge of the sheet overlapping the upper surface is straddled, and the edge is stretched along the edge. It is preferable to attach an adhesive tape and seal the overlapped portion.

The three-dimensional net-like sheet is formed by melting and spinning a thermoplastic synthetic resin or metal, irregularly deforming it three-dimensionally until it is cooled, and welding it to each other where it crosses or contacts each other. It is preferable to form a three-dimensional net-like sheet that is compression-resistant, flexible, and relatively bulky as a whole, in which large three-dimensional continuous pores communicating with the sheet are formed.
The upper surface of the above-mentioned water-permeable root-preventing sheet is placed in a longitudinal surrounding space of each row, and at least one of the longitudinally extending spaces having a width substantially equal to the width of the space is extended over the entire length in the space. To be placed and loaded. In this case, the height of the upper surface of the loaded three-dimensional net-like sheet is made lower than the height of the long plate surrounding the surrounding space, so that there is a space on the upper surface where soil can form an embankment layer. The loaded three-dimensional mesh sheet retains the filled soil in its three-dimensional continuous pores, prevents its movement, and maintains a packed layer of uniform thickness throughout. A soil covering layer having a desired thickness, which is deposited on the upper surface of the filling layer and covers the three-dimensional mesh sheet, is suitable for sowing and planting of turf, flowers and the like. Any type of soil can be used.
It is preferable to use one having a specific gravity at the time of water absorption specified in A 1109 of 1 or less.

Any of these waterproof sheets having an adhesive layer on at least one side can be suitably used, but asphalt-based sheets can be most preferably used from the viewpoint of waterproofness, ease of construction, and the like. The asphalt-based sheet is made of a nonwoven fabric or a woven fabric made of a natural fiber, an inorganic fiber or an organic synthetic fiber alone or a mixed fiber thereof as a base sheet, impregnated and coated with asphalt or polymer-modified asphalt, and further coated on one side thereof. Or provide an asphalt-based, rubber-based adhesive layer on both sides,
There is one obtained by temporarily attaching a release paper thereon. Further, in the case where the adhesive layer is provided on only one side of the asphalt-based sheet, the surface of the opposite side, that is, the surface of the asphalt coating layer on which the adhesive layer is not provided, has a mineral powder for the purpose of preventing adhesion. Particles, for example, silica sand, talc, etc. are adhered to make the surface non-adhesive.

It is preferable to cut the slits 4 and 4 in advance in the longitudinal direction in parallel with a slitter, leaving an overlap portion inside the inside. In such a case, the narrow width release paper portion 3a outside the cut 4 on one side of the waterproof sheet 2 previously attached and laid can be peeled off in a tape shape according to the cut 4, so that it should be newly bonded. The peeling paper 3 on the lower surface of the waterproof sheet 2 is peeled off to expose the overlapping portion where the adhesive surface is exposed along one side edge thereof. Is peeled off to expose the adhesive surface, and the overlapping margins on the opposite side are polymerized and pressure-bonded, so that the wide part of the wide release paper portion 3b at the center of the upper surface of the existing waterproof sheet 2 is sequentially peeled off. The superimposition of the adjacent waterproof sheets 2 and 2 can be smoothly performed.

In this case, in order to facilitate the erecting of these long plates, an L-shaped or T-shaped cross section having a bottom plate of a desired width to be nailed to a waterproof sheet surface at a lower end edge thereof as described later is used. It is generally preferable to use a long molded plate. FIG. 7 shows a long drainage forming plate 9 having a length suitable for transportation and construction work, which is provided with a bottom plate 8 which extends horizontally from the lower edge to one side for erecting the long draining plate 5. Is shown below. The long formed plate 9 for drainage is selected and used from a desired metal plate such as a stainless steel plate, a galvanized steel plate, a molten aluminum steel plate, a copper plate, and a titanium plate.
The plate thickness is about 0.3 to 0.8 mm, but is not limited to this. The height of the long drainage plate 5 rising vertically from the bottom plate 8 varies depending on the thickness and weight of the embankment of the soil to be deposited in the surrounding space 7 to be formed, the type of the plant to be planted, and the like. It is about 5 to 10 cm. However, it is a matter of course that the present invention is not limited to this. In the case of a synthetic resin, the thickness is preferably about 1 mm or more. Also, the rising drainage long plate 5 is used by selecting various lengths cut in advance to a predetermined length,
Alternatively, cut to an appropriate length at the construction site and use it. From the viewpoint of ease of construction work, it is general and preferable to select and use one in the range of 50 to 200 cm. The rising drainage long plate 5 has a drainage hole 5

As shown in FIG. 8, for ease of standing, a member formed on an elongate closing plate 11 having an L-shaped cross section and having a bottom plate 10 extending horizontally from the lower edge to one side is used. Is preferred. The bottom plate 10 is preferably provided with nail holes 10a at predetermined intervals. Its diameter is 5-7m
It is generally about m, but is not limited to this. The material and thickness of the long molded plate 11 for closing can be the same as those of the long molded plate 9 for drainage described above, made of metal or synthetic resin as described above. The height of the blocking long plate 6 is the same as the height of the draining long plate 5, and is generally 5 to 1 mm.
It is about 0 cm. Needless to say, the height is selected in consideration of the thickness of the embankment layer to be accommodated and deposited in the surrounding space 7 to be formed, etc. Was set to 10 cm, which is the same as that of the long drainage plate 5.
In addition, the length thereof may be, for example, the closing long plate 6 having a length substantially covering the entire length of the edge or the closing long formed plate 11 having the bottom plate at the lower edge thereof. From the viewpoint of facilitating the handling of construction work, etc., 50 to 200 c

Next, a large number of long drainage molded plates 9 shown in FIG. 7 are used, and the elongate closing elongate parallel to the eaves tip edge 1a and erected along both edges 1b, 1b. A plurality of rows of long drainage plates 5, 5,... Which are in contact with the inner surfaces of the plates 6, 6 and are parallel to each other at a predetermined interval in the gradient direction are erected as follows. That is, the long formed drainage plate 9 shown in FIG.

Toward and along the edge 1a, the wide bottom plate 8 is placed on the exposed adhesive surface with the wide bottom plate 8, and the nail 12 is inserted through the nailing holes 8a, 8a,. It is struck and nailed to the base material 1 of the base via the waterproof sheet 2 to stand upright. next,
A new elongate drainage molded plate 9 is arranged along the eaves tip edge in a state where one end of the elongate elongate molded plate 9 is already nailed, and is nailed in the same manner as described above. In the same manner, the drainage elongate molded plate 9 is successively overlapped with its adjacent end, and a row of drainage elongate plates 5 extending over substantially the entire length of the eave tip edge.
5, ... stand up. Next, while peeling off the release paper portions 3a and 3b of the release paper 3 of the waterproof sheet 2 in the second row, the bottom edge of the bottom plate 8 on the rising drainage long plate 5 side of the long drainage forming plate 9 is removed. The bottom plate 8 is placed on the adhesive surface of the waterproof sheet in a state of being superimposed on the upper edge of the bottom plate 8 of the long formed drainage plate 9 nailed in the first row, nailed at the upper edge, and so on. Then, the long drainage plates 5 in the second row composed of a plurality of pieces are placed in a row, and the drainage long molded plates 9 are placed in a row with the adjacent end portions superposed one on another and nailed. In this case, a desired plurality of rows, in the illustrated example, eight rows of the long drainage elongate plates 5 are arranged in parallel in the direction of the ridge end edge 1b at intervals of the wide bottom plate 8 of the long elongate drainage plate 9. , And the entire surface of the waterproof sheet 2 is covered with a plurality of rows of the bottom plates 8, 8,. The upper space on the entire surface of the laying surface is divided into seven rows of long spaces by seven rows of long drainage plates 5, 5, ... parallel to the eave tip edge 1a. The open spaces at both ends constitute a plurality of rows of enclosed spaces 7, 7,... As shown in FIG. 6 which are closed by long blocking plates 6, 6 extending along the edges of the both ends.

As is clear from the above, the long drainage plate 5
The elongate plate 6 for closing and the elongate plate 6 for closing are formed by elongating a long molded plate 9 having an L-shaped cross section with bottom plates 8 and 10 provided on one side of the lower edge thereof, respectively.
If 11 is used, it can be easily and easily erected. Also, in this case, the entire bottom surface of the waterproof sheets 2, 2,... Is covered with the wide bottom plate 8 of the long drainage molded plate 9 to provide fire protection, and at the same time, each of the long surroundings is provided by the laying. .. Has an effect of naturally defining the width of the spaces 7, 7,. Although not shown, a long formed plate having a T-shaped cross section, which is provided with a similar bottom plate having a desired width horizontally on both sides from the lower edge of each of the long plate for drainage and the long plate 6 for closing, is used. Needless to say, the same surrounding space can be formed and the same effect can be obtained.

Similarly, using the waterproof sheet 2, the long drainage forming plate 9 and the long closing closing plate 11, the same applies to the other side, that is, the rear sloped roof substrate 1 on the rear side. To form seven rows of long surrounding spaces 7, 7,....

The arrangement of the plurality of rows of the surrounding spaces 7, 7,...
A plurality of rows of draining long plates 5 may be set up in parallel with each other, and then the blocking long plates 6 and 6 on both sides along the edge may be set up. The interval between the plurality of parallel long drain plates 5, 5,...
When it is set to a range of about 00 cm, the flow of the embankment layer accommodated in the surrounding space 7 at a predetermined thickness can be prevented to stably maintain the embankment layer, and the embankment layer covering each long drainage plate 5 can be maintained. It was found that the burden on the user can be reduced, which is preferable.

Next, each of the surrounding spaces 7,
In 7, ..., a long rectangular water-permeable root-proof sheet 13 is superposed on the entire inner surface of each of the formed drainage long plates 5, 5 so as to cover the myriad small drain holes 5a, 5a, ....
In this case, in order to facilitate the polymerization work, the water-permeable root-preventing sheet 13 is, as shown in FIG.
A wide, long width having an intermediate surface region 13a laid on the bottom surface of the slab and both side surface regions 13b, 13b corresponding to the height of the long drainage plates 5, 5 facing front and rear across the bottom surface. It is preferable to use a roll. For example, the width of the bottom surface of the surrounding space 7 (the width of the bottom plate 8 in the embodiment) is 65
cm, and the height of the standing drainage long plate 5 is 10 cm, the water-permeable root-prevention sheet 13 having a width of 85 cm is used. Thus, when the water-permeable root-preventing sheet 13 is laid in the surrounding space 7 and the intermediate surface region 13a is laid on the bottom surface, the both side surface regions 13b and 13b naturally come into contact with the long drainage plate 5 surface. As a result, they are bent up and rise 5 cm along the surface of the long drainage plate 5 and polymerized on their respective inner surfaces, so that the polymerization work can be easily performed. The water-permeable root-prevention sheet 13 (13) which is polymerized on the opposed draining long plates 5 and 5, respectively.
It is preferable that b) and 13 (13b) are fixed to the long drain plates 5 and 5. For example, an adhesive 14 is applied to the corresponding corresponding drainage long plates 5, 5 at appropriate points along its length at its upper edge, for example, by applying hot water such as ethylene-vinyl acetate copolymer resin. It is applied in a dot shape with the melt adhesive 14 and fixed (see FIG. 10). The fixing means is preferably an adhesive in terms of work efficiency, but can be fixed to the long drainage plate 5 by any means such as a clip or a piece of adhesive tape.

The water-permeable root-preventing sheet 13 is made of a durable woven or non-woven fabric which is water-resistant and does not decompose by microorganisms in the soil. For example, polyester, polyvinyl chloride,
Synthetic resin fibers such as nylon, vinylon and acrylic are preferred. For example, a thin and light-weight material having a thickness of about 0.1 mm and a basis weight of about 60 g / m ² is preferable, and its water permeability is such that the water permeability specified in JIS A1218 is substantially the same as that of soil. ^-4 cm / sec or more, and those having an eye size of 30 μm or less are preferable, whereby the water permeability can be reliably ensured and the passage of the roots of the plant, particularly the hair roots such as whiskers, can be prevented. Accordingly, it is possible to prevent the small drain hole 5a of the long drain plate 5 from being blocked, and to secure drain water. In the illustrated embodiment, as the water-permeable root-prevention sheet 13, a woven fabric woven from synthetic fiber filament yarn and having the above conditions is used.

Thus, the water-permeable root-proof sheet 13 is
When using a roll-shaped material and laying it over the entire length of each surrounding space 7, using the roll-shaped water-permeable root-preventing sheet 13 on the way and using a new similar roll-shaped sheet As shown in FIG. 10, the edge of the new roll-wound sheet 13 is
Is laid, for example, in a state of being superimposed by 20 cm at the edge of the upper sheet 13 so as to prevent roots from entering between the overlapped portions of the upper and lower sheets, and along the edge of the upper sheet 13 and along the edge thereof. It is preferable that an adhesive tape 15 be attached along the entire length of the edge and over the entire width of the sheet 13 to seal the gap between the overlapping portions. As the adhesive tape 15, a tough synthetic resin film or the like is used.

Next, a large number of three-dimensional net-like sheets 16 each having a width substantially equal to the width of the surrounding space 7 and having a desired length that is easy to carry and perform work are placed in each of the surrounding spaces 7. Use and load over its entire length. As the three-dimensional net-like sheet 16, for example, it is preferable to use a roll-shaped sheet as shown in FIG. That is, the three-dimensional network 16 is formed by melt-spinning a thermoplastic resin such as polypropylene, polyethylene, polyester, nylon, or polyvinyl chloride from a nozzle having a diameter of about 1 to 3 mm.
Until the 条 3 mm filament 16a cools and solidifies, it is irregularly curved and deformed three-dimensionally, and the mutually curved yarns 16a are welded to each other to form a bulky three-dimensional body having a thickness of about 1 to 3 cm. The bulky thickness is, for example, 30 mm formed to have a three-dimensional large continuous hole 16b communicating with the inside and outside by the three-dimensional mesh wire. When the width of the surrounding space 4 is 65 cm, for example, the width is about 63 cm, and the length is a flat plate suitable for transportation and construction work or a roll as shown in the drawing. Prepare and use many of them. Thus, for example, when the length of the surrounding space 7 is approximately 9 m, for example,
Lay them together, or unwind a roll of approximately 9 m in length. In addition, the height of the loaded three-dimensional net-like sheet 7 is shown in the figure as an example in which three sheets each having a thickness of 3 cm are stacked. Absent. The height is selected according to the height of the surrounding space 7 to be formed and the height of the space to be formed on the upper surface of the loaded mesh sheet.

The line 16a of the three-dimensional net-like sheet 16
Is not limited to a synthetic resin, but may be a metal filament. In this case, a material having corrosion resistance is preferable, and examples thereof include a stainless steel wire and a galvanized steel wire. The three-dimensional net-like sheet 16 thus prepared is loaded over the entire length of each of the surrounding spaces 7 in the longitudinal direction.

Thus, the height of each surrounding space 7 is
The water-permeable root-prevention sheet 13 is loaded to an appropriately low height, and a space for forming a soil covering layer having a predetermined thickness is provided above the loaded sheet 13. For example, the height of the surrounding space 7, that is, the height of the draining long plate 5 and the closing long plate 6 is 10 cm, and the thickness (height) of the three-dimensional net-like sheet 16 to be loaded. Is 3 cm,
For example, three three-dimensional net-like sheets are stacked, and the three-dimensional net-like sheet 16 is loaded to a thickness of 9 cm, and a space of 1 cm for the covering layer is left on the upper surface thereof. Of course, the thickness of the space for the earth covering layer on the upper surface is appropriately selected depending on conditions such as the type of plant to be planted.
The thickness of the cover layer space can be changed as desired, for example, the thickness of the cover layer layer is set to about 7 cm or 4 cm. Generally, the above-mentioned three-dimensional net-like sheet is selected from those having a thickness of 1 to 10 cm according to the height of the surrounding space.

Next, after the three-dimensional net-like sheet 16 is loaded, the desired type of soil is filled in each surrounding space 7 to the full height or to the vicinity thereof, and the embankment layer having a desired thickness is formed. A planting section 18 is formed and provided to form the slope 17 and the construction of the sloped roof of the present invention is completed. In the filling of the soil, the soil is completely filled in the large three-dimensional continuous holes 16b of the three-dimensional mesh sheet 16, and the soil of the filling layer 17a is filled with the three-dimensional mesh wire 16a.
By this, the movement can be prevented and good protection can be obtained, which is preferable. The soil deposited on the upper surface of the filling layer 17a covers the upper surface of the three-dimensional net-like sheet 16 laminated in three layers to form a covering soil layer 17b having a predetermined thickness. The soil covering layer 17b not only covers the three-dimensional net-like sheet 16 to improve appearance, but also acts as a soil layer suitable for growing seeds to be planted and growing grass and flower roots, The three-dimensional net-like sheet 16
The three-dimensional large continuous pores 16b of the above work to allow root invasion. Thus, a multi-row planting construction section 1
8, 18, ... are provided to provide a planting construction body with a sloped roof of the present invention.

In the case of a wooden sloping roof base, the height of each surrounding space 7 is appropriately determined in consideration of the load of the soil filled and formed therein. However, it is preferable to mix relatively light inorganic powder or to use light soil alone. According to Japan's Building Standards Law Enforcement Order Article 84, in the case of a wooden roof, for example, when the fixed load of the roof is
According to the regulation, it is set to 0 kg / m ² or less.
m, the edge length of which is 4.7 m, the thickness of the embankment layer in the water-absorbing state is limited to a maximum of about 10 cm, and accordingly, the height of the surrounding space 7, that is, the surrounding long plate The height of 5, 6 is limited to a maximum of 10 cm. in this case,
As the soil, a lightweight soil having a specific gravity of 1 or less at the time of water absorption specified in JISA 1109 (test method for specific gravity and water absorption of fine aggregate) is preferable. Examples of such soil include obsidian pearlite, vermiculite, peat moss and the like, and these are used alone or as a mixture.

Thus, each of the soil cover layers 17b, 17b,
In addition to turfgrass such as Japanese turf, western turf, crow's whiskers, wildflowers, etc., suitable plants are planted or seeds are sown to green the roof.

As described above, according to the present invention, a waterproof sheet is laid on the entire upper surface of the sloped roof foundation, and a plurality of parallel drainage long plates are provided on the upper surface at intervals in the gradient direction. Along with the erected edges of these long plates for drainage, along with the edges, a long plate for closing is erected, and the upper surface space of the waterproof sheet is divided into a plurality of rows orthogonal to the gradient direction. Divided into surrounding spaces, in each surrounding space, on the inner surface of each long drainage plate perpendicular to the gradient direction, a water-permeable root-proof sheet is superimposed, and further a three-dimensional net-like sheet is placed in the surrounding space. A plurality of rows having an embedding layer which is loaded and filled with soil into three-dimensional large continuous holes of the loaded three-dimensional net-like sheet, and furthermore an embankment layer is formed on the upper surface of the packed layer. Since the planting construction area was composed,
An embankment layer of a predetermined thickness can be stably held in each of the planting construction sections, and excess rainwater that has infiltrated each of the sectioning sections has a respective drainage area located downstream of each section. Through the innumerable small drainage holes of the long plate for drainage, it flows down along the slope in order, and is discharged to the outside from the longest drainage plate in the bottom row. The flow deformation, collapse, and loss of the embankment layer caused by a large amount of rain as in the past can be eliminated. Furthermore, thin roots such as desired flowers and turf planted in the covering soil layer of each planting construction section penetrate into the filling layer in the three-dimensional continuous pores, and the growth thereof can be secured. In addition, since the water-permeable root-prevention sheet covers the long drainage plate, it allows water permeation while preventing the passage of the whiskers, and countless drain holes of the long drainage plate are closed by this. This can be prevented beforehand, and good drainage of the long drainage plate can be ensured.

In the construction of the roof sloping roots of the palm-shape type where the edges of the ridge are located opposite to each other, the front and rear closing lengths erected along the edges on both sides of each sloping roof sill. The V-shaped ridge space generated between the upper ends of the scale plates is closed with a ridge closing plate, a waterproof sheet is laid across the ridges, and a waterproof sheet is laid across the edges of both ridges. When constructing the planting construction section in the surrounding space of the row in the same manner as above, the planting construction including the ridge can be completed.

The above-mentioned long plate for drainage and long plate for closing can be easily and easily prepared by preparing a long plate having an L-shaped or T-shaped cross-section and fixing the bottom plate to the surface of the base material. Can be stable. In this case, when the adjacent edges of the long plate for closing are overlapped, waterproofness on the edge side can be ensured. In addition, when a cut is made in both side edges of the release paper on the upper surface of the waterproof sheet, only the release paper on one side edge can be peeled off, and the tape can be peeled off. Standing work can be done smoothly and easily.

When the water-permeable root-prevention sheet is superposed on the inner surface of the opposed draining long plate, a water-permeable root-proof sheet having a width from the bottom surface of each surrounding space to the opposing inner surface of the draining long plate is used. When used, the polymerization operation is facilitated, and the waterproof sheet on the lower surface can be prevented from being damaged by roots. Further, the polymerized state of the water-permeable root-prevention sheet covering the inner surface of the drainage long plate can be stably maintained by fixing it to the facing drainage long plate with an adhesive or the like.

When the water-permeable root-proof sheet is made of synthetic resin fiber woven fabric or non-woven fabric, it is durable and advantageous, and in particular, has a water permeability coefficient of 10 ⁻⁴ cm stipulated in JIS A1218. When the size of the eyes is not less than / sec and the size of the eyes is not more than 30 μm, the drainage performance is good, the thin roots of the whiskers do not pass, and the water permeation and the root prevention are surely provided. In particular, a woven fabric woven with a synthetic resin filament yarn can be used to produce a flexible and tough material having such conditions.

The three-dimensional net-like sheet is formed by melt-spinning a synthetic resin or metal, irregularly deforming the yarn three-dimensionally until the yarn cools, and welding it at points where it comes into contact with each other. When configured to have bulky compression resistance with continuous three-dimensional large continuous pores,
While soil can be filled and held in three-dimensional large continuous pores, and root infiltration into the packed bed and growth can be secured,
It is not decomposed by soil bacteria, is corrosion resistant and can be used for a long time.
