  By the way, in patent document 1, since the drainage part and the cultivation part are installed using the valley-shaped part of the folded-plate roof itself, the folded-plate roof stays in the cultivation part and is discharged from the drainage part. There was a problem that it deteriorated at an early stage, such as rusting when exposed to moisture. In addition, when the folded-plate roof is exposed to sunlight and becomes hot, the cultivation part is heated by the heat and the roots of the plants die and die, and the indoor thermal environment covered with the folded-plate roof is adversely affected. There was also a problem. Moreover, in any of Patent Documents 2 and 3, a groove plate on which a planting mat material and a cultivation part are laid is arranged perpendicular to the mountain part where the gradient may be set. Therefore, the water staying in the planting mat material and the cultivation part in the groove plate cannot be drained easily and smoothly due to the action of gravity and the like, thereby causing a problem that root rot easily occurs.

  EMBODIMENT OF THE INVENTION Below, suitable one Embodiment of the folded-plate roof greening system concerning this invention is described in detail with reference to an accompanying drawing. As shown in FIGS. 1 to 5, the folded-plate roof tree planting system according to the present embodiment basically includes a folded-plate roof 1 installed so as to be inclined so that the ridge line direction D of the mountain portion P is inclined. A plurality of fixtures 2 installed at appropriate positions of the mountain portion P, and a plurality of fixtures installed and fixed in a direction crossing the ridge line direction D of the mountain portion P of the folded plate roof 1 across the fixtures 2 The support material 3 and the deep groove 4a and the shallow groove 4b, which are grooves, are installed on the support material 3 along the ridge line direction D of the mountain portion P of the folded plate roof 1 so as to cover the folded plate roof 1, A corrugated plate-like support substrate 4 that supports the greening base 5 with an appropriate space S between the valley V of the plate roof 1 is provided.

  Further, a drainage member 6 such as a basket is provided at the edge of the support substrate 4. The planting base 5 is planted in which a plant 9 is planted on a heat-insulating water-permeable layer 8 that is fixed to the support substrate 4 via fasteners 7 and has a number of continuous drainage paths from the upper surface toward the lower surface. Layer 10 is formed and configured. The planting layer 10 should just be formed with the material which has the moderate water retention required for the plant 9 to grow, and the moderate drainage property which does not produce root rot. In addition to general soil, peat moss etc. Artificial materials such as moss deposits and thinned wood chips are used. The support substrate 4 is provided with a weir member 11 that regulates the movement of soil along the direction intersecting the ridge line direction D of the mountain portion P of the folded plate roof 1. An irrigation pipe 12 is provided between the deep groove 4 a of the support substrate 4 and the greening base 5.

  As is well known, the folded plate roof 1 is formed in the form of a corrugated plate with a peak portion P and a valley portion V being continuous. Specifically, it is formed by arranging a plurality of approximately U-shaped roof pieces 13 and fitting or screwing together adjacent roof pieces 13 at the peak P position. In the illustrated example, the folded-plate roof 1 has a planar outer contour that is formed in a rectangular shape. Normally, the folded-plate roof 1 has one edge in the width direction along the ridge line direction D of the mountain portion P as the upper edge portion 1a and the other edge as the lower edge portion 1b so that the ridge line direction D of the mountain portion P is inclined. Inclined (see FIG. 2 and FIG. 5). The folded plate roof greening system according to the present embodiment can be applied regardless of whether the folded plate roof 1 is existing or newly installed.

  The fixture 2 is installed at an appropriate mountain portion P and an appropriate position of the mountain portion P among the many mountain portions P included in the folded plate roof 1. The installation position of the fixture 2 is variously determined in consideration of the arrangement of the support member 3 while considering the load distribution of the greening base 5 installed on the folded plate roof 1. In the present embodiment, as shown in FIG. 2, the fixture 2 has a staggered arrangement on the roof surface of the folded plate roof 1 in an inclined direction, three at the top, two at the center, Three are installed at the bottom. When the greening base 5 is heavy, it is also possible to install three in the upper part, three in the central part, and three in the lower part in a grid pattern.

  Specifically, the fixture 2 is a seat portion 14a, a pair of leg portions 14b protruding in the same direction from both ends of the seat portion 14a, and a pair of inwardly bent portions facing each other from the tips of the pair of leg portions 14b. A tightening screw that narrows the space between the leg portions 14b by tightening and tightening the grip 14 that is formed in a substantially C-shaped cross section from the claw portion 14c and the pair of leg portions 14b. 15. The fixture 2 has a pair of claw portions 14c placed on a pair of flat portions 16 formed with a fitting portion of the folded plate roof 1 sandwiched therebetween, and the claw portions 14c are connected to the flat portion 16 in a pair. The fitting state of the claw portion 14c placed on the flat portion 16 in the fitting groove 17 is maintained by tightening the tightening screw 15 and narrowing the interval between the leg portions 14b in the state of being fitted in the fitting grooves 17 respectively. And fixed to the mountain portion P of the folded-plate roof 1.

  On the seat 14 a of the fixture 2, the support member 3 is installed across at least two fixtures 2. These support members 3 are installed in a direction intersecting with the ridge line direction D of the mountain portion P of the folded-plate roof 1, for example, a direction perpendicular to the ridgeline direction D (in the illustrated example, the length direction of the folded-plate roof 1). Therefore, the direction of the support member 3 may be other than the direction orthogonal to the ridge line direction D. In the present embodiment, as shown in FIG. 2, the support member 3 is formed in a long length over the entire length in the length direction of the folded plate roof 1, and the fixture disposed in the above 3-2-3. Three are provided at two installation positions so as to be orthogonal to the ridge line direction D.

  Of course, the support material 3 may be formed shorter than the length of the folded roof 1 according to the size of the greening base 5, and the number thereof may be adjusted. In the present embodiment, a C-shaped channel material is employed as the support material 3 in consideration of light weight and good handleability. The support member 3 made of the C-shaped channel material is fixed to the fixture 2 with a fastener (not shown). Of course, the support material 3 other than the channel material such as an angle material or a hollow square pipe may be used in consideration of the required rigidity. The fixture 2 has an appropriate form in accordance with the support material 3.

  On these support members 3, a support substrate 4 is installed across at least two support members 2, so that the lower side of the support substrate 4 is between the valley V of the folded plate roof 1. An appropriate space S is formed. A large number of the spaces S are formed in series in the width direction of the folded plate roof 1 from the lower edge portion 1b to the upper edge portion 1a and in the length direction. The support substrate 4 is installed so as to cover the folded plate roof 1 within the range of the planar outer dimensions thereof, and includes not only the case of covering the entire folded plate roof 1 but also the case of partially covering it. The support substrate 4 is formed in a corrugated plate shape so that the deep grooves 4a and the shallow grooves 4b are alternately adjacent to each other through the flat portion 4c. Therefore, since the cross-sectional performance is higher than that of a normal flat plate, the cross-sectional performance can be reduced and the weight can be reduced. The deep groove 4 a portion of the support plate 4 is placed in contact with the support material 3. In particular, the support substrate 4 is arranged so that both the deep groove 4a and the shallow groove 4b are along the ridge line direction D of the mountain portion P of the folded plate roof 1, in other words, along the inclined direction of the folded plate roof 1. The The support substrate 4 is preferably formed of a corrosion-resistant material, and is bonded to the support material 3 at an appropriate position by a corrosion-resistant screw 18 or the like.

  In addition, the support substrate 4 is provided with a drainage member 6 such as a gutter at its peripheral edge, particularly at the lower edge 4d on the lower edge 1b side of the folded roof 1 as shown in FIG. The drainage member 6 may be provided also on the side edge 4e on both sides along the ridge line of the mountain portion P of the folded plate roof 1 with the lower edge 4d side in between. The drainage member 6 is a folded plate that is disposed so as to face the lower end edge 4d and the side edge 4e of the support substrate 4 even when joined to the lower end edge 4d and the side end edge 4e of the support substrate 4 or as shown in the drawing. You may join to the lower edge 1b of the roof 1, or a side edge. Considering good air permeability between the support substrate 4 and the folded-plate roof 1 described later, the drainage member 6 is preferably attached to the folded-plate roof 1. Even in that case, as shown in FIG. 3, the lower end edge 4 d of the support substrate 4 protrudes from the lower edge portion 1 b of the folded plate roof 1, and the drainage member 6 is provided on the lower edge portion 1 b of the folded plate roof 1. For example, the entire surface of the folded-plate roof 1 can be covered with the planting layer 10 on the support substrate 4 to form a green roof that is excellent in aesthetics, as well as from the drainage from the support substrate 4 and the folded-plate roof 1. Since a single drainage member 6 can also be used for drainage, a labor-saving configuration can be achieved.

  On the support substrate 4, the greening base 5 is supported by the support substrate 4 with an appropriate space S between the folded plate roof 1 and the valley V as described above. Although not shown, the greening base 5 is formed on a light-insulating water-permeable layer 8 made of, for example, polystyrene, and a heat-insulating water-permeable layer 8 in which a number of drainage channels are formed like a mesh by foaming or the like. And a planting layer 10 on which the plant 9 is planted. The drainage path may be formed by a method such as drilling a large number of fine holes without depending on means such as foaming.

  The heat-insulating water-permeable layer 8 has excessive water in the planting layer 10 so that the planting layer 10 is not overflowed with water and the root of the plant 9 is not lifted up or soil is discharged. In order to prevent root rot, these excess water and excess water are quickly drained into the deep groove 4a of the support substrate 4, and the appropriate moisture necessary for growing the plant 9 is always maintained in the planting layer 10. The drainage of the planting layer 10 should be adjusted as long as it has a number of drainage paths through which the drainage from the planting layer 10 passes toward the support substrate 4. For example, a porous material Or spongy material. Moreover, since the wastewater containing the fertilizer from the planting layer 10 distribute | circulates, you may form with the material which has corrosion resistance and a weather resistance, for example, an inorganic material and a synthetic resin material. Furthermore, since it is also desirable that it is lightweight and has a heat insulating performance, it is preferable to form it with a foaming synthetic resin material having this.

  The heat insulating water permeable layer 8 is fixed to the support substrate 4 by an appropriate fastener 7 having a corrosion resistance such as a synthetic resin. In this embodiment, the planting layer 10 is formed by embedding soil on the heat-insulating water-permeable layer 8. And the plant 9 is planted in this filled soil. And the shallow groove | channel 4b and the deep groove | channel 4a of the support substrate 4 which support the said greening base | substrate 5 use the inclination of the folded-plate roof 1 for the moisture which flows out from the drainage path | route of the planting layer 10 and the heat-insulating water-permeable layer 8. Functions as a drainage for natural drainage.

  In order to restrict the soil on the heat-insulating permeable layer 8 from being scattered on the support substrate 4 or moving and collapsing according to the inclination of the folded-plate roof 1, the ridge line direction D of the mountain portion P of the folded-plate roof 1, That is, the weir member 11 is fixed along the direction intersecting the inclination direction of the folded-plate roof 1, and in this embodiment, as shown in FIG. 2, along the length direction of the folded-plate roof 1. In the illustrated example, three weir members 11 are provided at intervals in the width direction of the folded-plate roof 1 so as to correspond to the positions of the support members 3. What is necessary is just to set the number of installation of the dam member 11 suitably according to the quantity of soil and the inclination angle of the folded-plate roof 1. FIG.

  The dam member 11 is formed of a long plate material having a height that protrudes upward from the planting layer 10 from the support substrate 4. About the protrusion part 11a protruded from the planting layer 10, in order to catch the soil which collapses and moves, it is also possible to bend and form toward the upward direction of an inclination. Since the weir member 11 is provided so as to penetrate the planting layer 10 and the heat-insulating water-permeable layer 8 having a drainage path, it is preferably formed of a synthetic resin material or a metal material having corrosion resistance. In the present embodiment, the dam member 11 prevents the scattering and collapse of the soil. However, the root of the plant 9 extends to wrap up the soil, and further to the drainage path of the heat-insulating permeable layer 8 and the like. By entering, it becomes possible to prevent scattering and collapse of the soil.

  Moreover, between the lower surface of the heat-insulating permeable layer 8 of the greening base 5 and the deep groove 4a of the support substrate 4 immediately below, the heat-insulating permeable layer 8 is sandwiched between them and along the length direction of the deep groove 4a. An irrigation pipe 12 for supplying water as needed is provided using the capillary phenomenon by the drainage path. When the water supply pressure from the irrigation pipe 12 is set high, a relatively large water supply hole may be formed in the heat insulating permeable layer 8. The irrigation pipe 12 is also preferably formed of a synthetic resin material or metal material having corrosion resistance. Furthermore, on the planting layer 10 of the tree planting base 5, there is provided a irrigation tube 19 which is located at the periphery and supplies water to the planting layer 10 and thereby prevents the scattering of the soil. Positioned, a sprinkler 20 for irrigation is provided.

  The operation of the folded-plate roof greening system according to the present embodiment having the above-described configuration will be described. When installing the greening system on the folded-plate roof 1, regardless of existing or new installation, the grip 14 is tightened with a screw 15. A plurality of fixtures 2 are installed on the mountain P, and then the support material 3 is installed between the fixtures 2, and then the support substrate 4 is installed on the support material 3 with screws 18 or the like. . At this time, the irrigation pipe 12 is mounted along the appropriate deep groove 4a. Thereafter, the heat-insulating water-permeable layer 8 constituting the greening base 5 is placed on the support substrate 4, and the heat-insulating water-permeable layer 8 is fixed to the support substrate 4 with a fastener 7 or the like. At this time, the weir member 11 is also fixed to the support substrate 4. Thereafter, the soil is further embanked as a planting layer 10 on the heat-insulating water-permeable layer 8. Moreover, on this planting layer 10, the irrigation tube 19 and the sprinkler 20 are installed as needed.

  Thus, in the tree planting system installed using the folded-plate roof 1, since the heat-insulating water-permeable layer 8 was provided on the lower side of the planting layer 10, excess water due to rainfall is removed from the heat-insulating water-permeable layer. 8 is quickly drained into the deep groove 4 a of the support substrate 4, and it is possible to prevent the planting layer 10 from overflowing with excess water, causing the roots of the plants 9 to rise and the soil from flowing out. Water stays and root rot does not occur. If necessary, water is supplied from the irrigation tube 19 or the sprinkler 20 to constantly grow the plant 9 in the planting layer 10. It can retain the necessary moderate moisture.

  Furthermore, since the waste water staying in the planting layer 10 and discharged therefrom can be received and drained by the deep grooves 4a and the shallow grooves 4b of the support substrate 4, and the drainage is not received by the folded plate roof 1, The durability of the folded plate roof 1 can be improved. Further, as described above, the folded plate roof 1 is configured by fitting the roof pieces 13 to each other or fastening them together. Although there is a problem with water, such a problem can be solved. In particular, with respect to the folded plate roof 1 installed so as to be inclined such that the ridgeline direction D of the mountain portion P is inclined, the deep groove 4a and the shallow groove 4b are along the ridgeline direction D of the mountain portion P. Thus, the deep grooves 4a and the shallow grooves 4b are inclined toward the lower end edge 4d of the support substrate 4 and can be drained easily and smoothly. It can prevent root rot caused by the retention.

  In addition, as shown in FIG. 5, the greening base 5 is supported by the support substrate 4, and from the lower edge 1 b of the folded plate roof 1 between the support substrate 4 and the valley portion V of the folded plate roof 1. Since a large number of spaces S communicating in series toward the upper edge portion 1a are formed, the space S can be used for ventilation, and the folded-plate roof 1 is exposed to solar radiation and heated. In addition, even if the greening base 5 absorbs a considerable amount of heat, the heat-insulating action of the space S is combined with the ventilation function to take heat away, thereby suppressing the temperature rise on the greening base 5 side and the folded-plate roof 1 side. It is possible to prevent the roots of the plant 9 from withering and dying, and to maintain a comfortable thermal environment in the room covered with the folded roof 1.

  In addition, since the greening base 5 is configured by installing the heat-insulating permeable layer 8 under the planting layer 10, the heat absorbed by the planting layer 10 is also affected by the heat insulating performance of the heat-insulating permeable layer 8. It is possible to prevent heat from being radiated to the folded plate roof 1 side, and thus to the room, and it is possible to maintain the indoor thermal environment well. Furthermore, since the planting layer 10 is soil, watering can be sufficiently performed, and the temperature is lowered by the heat of vaporization generated by the transpiration action from the soil surface of the planting layer 10 and the leaf surface of the plant 9. Thus, the heat insulation effect for the room can be improved and the heat island phenomenon can be effectively suppressed.

  Since the support substrate 4 is supported by the fixture 2 that can be installed at an appropriate position of the mountain portion P with respect to the folded plate roof 1 and the support material 3 that is spanned according to the arrangement of the fixture 2, By adjusting the arrangement and number of these fixtures 2 according to the load, it is possible to adjust the arrangement and number of the support members 3, and the greening base 5 is appropriately mounted on the folded plate roof 1. Can be supported. Moreover, the whole structure can be reduced in weight by the fixture 2, the support material 3 which consists of C-shaped channel material, the corrugated plate-shaped support substrate 4, and the heat-insulating water-permeable layer 8, and it can construct with the outstanding handleability. On the other hand, since the drainage member 6 is provided on the lower edge 4d and the side edge 4e of the support substrate 4, the drainage from the greening base 5 prevents the periphery of the folded plate roof 1 from being contaminated, and the efficiency is improved from the support substrate 4. It can drain well. Furthermore, if the lower end edge 4d of the support substrate 4 protrudes from the lower edge portion 1b of the folded plate roof 1, and the drainage member 6 is provided on the lower edge portion 1b of the folded plate roof 1, the entire surface of the folded plate roof 1 is supported by the support substrate. In addition to forming a green roof that can be covered with the planting layer 10 on the top 4 and aesthetically superior, the drainage from the support substrate 4 and the drainage from the folded roof 1 can be performed with a single drainage member 6. Since it can also be used for drainage, a labor-saving configuration can be secured.

  Further, by providing the weir member 11, the planting layer 10 can be prevented from being scattered or collapsed, and the planting layer 10 can be filled with soil or softened without using solidified or bagged soil. It can be formed by soil solidified to the ground, and can be held on the folded roof 1 by suppressing the displacement of the planting layer 10 against the horizontal force during an earthquake. Further, the prevention of scattering of the soil can be ensured by the roots of the plant 9 itself rooted in the soil. In addition, since the irrigation pipe 12 is provided under the greening base 5 using the deep groove 4a of the support substrate 4, maintenance is difficult when the irrigation pipe is installed in the greening base, In the present embodiment, the irrigation pipe 12 can be pulled out from the deep groove 4a, and the irrigation pipe 12 can be easily maintained and replaced.
