  In the folded plate roof greening structure shown in FIG. 9 in which a foamed resin heat insulating plate is attached on the standing folded plate roof to form a flat surface, and the greening base material is fixed thereon, the wind acting on the roof One requirement is to have a high resistance to the negative pressure generated by. In recent years, it has been demanded that rooftop greening be applied even to folded-plate roofs of tall buildings with a height exceeding 20 m or 30 m. The higher the height from the ground, the more negative the wind is. Since the pressure rapidly increases, it has become necessary to provide higher stability than that conventionally required for rooftop greening structures.

  This invention makes it a subject to disclose the fixation structure which fixes a greening base material on a standing folded-plate roof which can answer said request | requirement.

  The fixing structure for fixing the greening base material on the folded plate roof according to the present invention basically has a pair of clamp pieces sandwiching the standing protrusion from the left and right sides. A fixed clamp, and a foamed resin heat insulating plate attached to the roof surface so that the folded plate roof becomes a flat surface by using a clamp piece of the fixed clamp, and a protrusion of the standing portion A long pressing member having a length extending over a plurality of clamps fixed along the direction of the strip, disposed on a foamed resin heat insulating plate attached to the roof surface, and the clamp piece A long pressing member sandwiching the foamed resin heat insulating plate in between, a column erected on the pressing member, and fixed on the foamed resin heat insulating plate using the column It is characterized by having at least a greening base material.

  In the structure for fixing the greening base material to the standing folded roof according to the present invention, the foamed resin heat insulating plate attached to the roof surface using the clamp piece of the clamp fixed to the standing folded portion is It is stably fixed with the attitude | position pinched between the said elongate holding member arrange | positioned in the said, and the said clamp piece. Moreover, the said greening base material is fixed on the said foamed resin heat insulating board with the support | pillar standingly arranged in the said elongate holding member. Therefore, the fixing of the foamed resin heat insulating plate and the greening base material to the folded roof is strong and stable, and exhibits high resistance to negative pressure generated by the wind blowing on the roof.

  Although the said elongate holding member is not limited, It is desirable to make with a metal plate like stainless steel, and the horizontal width is about 50-200 mm. The elongate pressing member may be simply a flat plate or may have a T-shaped cross section provided with a vertical member that enters a joint portion between adjacent foamed resin heat insulating plates.

  In the present invention, as a member such as a clamp, a foamed resin heat insulating plate, and a greening base material, a conventionally known member as described in Patent Document 1, for example, can be used as it is. For example, examples of the resin material constituting the heat insulating plate made of foam resin include a foam polystyrene resin, a foam polypropylene resin, a foam polyethylene resin, and a urethane foam resin. The greening base material is preferably made of a foamed resin from the viewpoint of lightness and ease of molding, but may be made of a material such as a non-foamed resin or foamed mortar. The planting base material may have a form in which a planting layer made up of a guest soil layer or the like is accommodated as it is, or may have a water retention / drainage function and a planting layer placed thereon.

  In a preferred embodiment of the structure for fixing the greening base material to the folded plate roof according to the present invention, a non-woven fabric is disposed so as to cover the greening base material, and the non-woven fabric stands at least on the long pressing member. It is fastened to the supported pillar. In this aspect, the resistance to the negative pressure generated by the wind blowing on the roof can be further enhanced by the pressing effect of the nonwoven fabric.

  The present invention is also characterized in that a plant is vegetated on the greening base material fixed by the above-described fixing structure of the greening base material to the standing folded plate roof. A structure is also disclosed. The mode of vegetation planting may be the same as in the case of conventionally known rooftop greening. A soil may be laid in the greening base material, and a plant may be cultivated there, or a vegetation aspect in which an appropriate known planting layer is laid on the greening base material. In any case, it is desirable that the vegetation base material is a base material having water retention and drainage that allows water to flow more than necessary.

  According to the present invention, on a folded plate roof, it is possible to show high resistance against negative pressure caused by wind blowing on the roof, and greening in a state having a high heat insulating effect on the roof. The base material can be fixed. Further, by planting the plant on the greening base material fixed in such a manner, a rooftop greening structure having a stable structure can be constructed on a folded plate roof.

  Hereinafter, the present invention will be described based on embodiments with reference to the drawings. FIG. 1 shows an example of a folded plate roof, and FIG. 2 shows a clamp and a long pressing member used in the present invention. FIG. 3 is a view for explaining a mode in which the clamp shown in FIG. 2 is attached to the ridge of the folded-plate roof, and FIG. 4 is an illustration of the top of the folded-plate roof using the clamp thus fixed. Fig. 5 shows a state where the foamed resin heat insulating board and the greening base material are fixed. FIG. 5 is a plan view thereof. FIG. 6 is a diagram for explaining another embodiment of the fixing structure of the greening base material according to the present invention. FIGS. 7 and 8 are standing views made using the greening base material fixed by the fixing structure according to the present invention. The folded roof greening structure is shown.

  First, an example of a standing folded plate roof R will be described with reference to FIG. As shown in FIG. 1 (a), the standing folded-plate roof R has a long shape in which curved portions 3a and 3b that engage with each other are formed at the upper ends of the left and right rising edges shown in cross section in FIG. The shaped roofing plate 3 is fixed on the beam 5 using a dedicated attachment 6 while engaging the curved portions of the adjacent roofing plates 3 and 3 (splice joints). A mountain-shaped portion 1 that runs in the X direction that is the roof gradient direction is continuous at a predetermined pitch Pa in the Y direction that is the eaves direction. And the top part 2 of the said mountain-shaped part 1 is running in the roof slope direction with the protrusion 4 (the standing edge) with the roundness when the roof board 3 is connected. A foamed resin heat insulating plate 40 and a greening base material A (see FIG. 5 and the like) are fixed on such a standing folded plate roof R to form a standing folded plate roof greening structure according to the present invention.

  FIG. 2 shows a clamp 60 used therein and a long pressing member 80 fixed thereto. The clamp 60 includes a pair of left and right clamp pieces 61 and 61 having a certain lateral width. Each clamp piece 61 includes a bulging portion 63 composed of a sandwiching tip portion 62a that holds down the lower region of the protruding ridge 4 and a first horizontal portion 62b thereabove, and the tip of the sandwiching tip portion 62a. A vertical portion 64 rising from the first horizontal portion 62b at a vertical position substantially the same as the position, and a second horizontal portion 65 positioned at the upper end of the vertical portion 64. The vertical portion 64 includes left and right clamp pieces. Bolt holes 66 are formed for bolts used when 61 and 61 are tightened together. Further, the second horizontal portion 65 is formed with a bolt hole 67 for attaching a long pressing member 80.

  The shape on the inner surface side of the bulging portion 63 is preferably a shape that matches the outer shape of the protruding ridge 4 that is standing, and the size of the bulging portion 63 is a protrusion when the left and right clamp pieces 61 and 61 are tightened. The size is such that the strip 4 is slightly compressed and deformed. However, the shape on the inner surface side of the bulging portion 63 is such that when the left and right clamp pieces 61, 61 are tightened, the inner peripheral surface thereof is in partial contact with the ridge 4 or not in contact with it at all. There is no problem. Further, in the illustrated example, the leading ends of the sandwiching tip portions 62a and 62a are sharp, but the tip can be bent outward and the surface that contacts the protrusion 4 can be curved.

  When the clamp 60 is fixed, as shown in FIG. 3, the ridge 4 is sandwiched between the bulging portions 63 of the left and right clamp pieces 61, 61, and the bolt holes 66 formed in the vertical portions 64 of both are inserted. Tighten with nuts through bolts. The clamp 60 is fixed to the ridge 4 in a state where the ridge 4 is pressed from both sides by the tip of the sandwiching tip 62 having a certain lateral width and the inner surface side of the bulging portion 63, so that the clamp 60 is fixed. Is very stable.

  The long pressing member 80 is made of, for example, a metal material such as stainless steel. When the pair of left and right clamp pieces 61 and 61 are attached to the vertical protrusion 4, However, the present invention is not limited to this. In the normal case, it is in the range of 50 to 200 mm, and most commonly around 100 mm. The length of the long pressing member 80 is at least between two adjacent clamps 60 in the plurality of clamps 60 fixed to the protrusion 4 in the X direction (see FIG. 1) which is the roof gradient direction. The length that can be.

  On the long pressing member 80, a required number of screw rods 70 functioning as support columns are erected at a required interval, which will be described later, and opposed to the clamp 60 fixed when arranged on the roof surface. Bolt holes 81 and 81 are formed at positions where the bolt holes 67 and 67 are formed in the second horizontal portion 65 of the clamp pieces 61 and 61. In addition, when these are fixed using a drill screw etc. without using a bolt nut, the bolt holes 66, 67, 81 may be omitted, and a small hole may be formed instead of the bolt hole.

  As described above, after fixing the plurality of clamps 60 to the necessary portions of the protruding ridges 4, the foamed resin heat insulating plate 40 and the greening base material A are raised and folded using the clamps 60. It is fixed on the plate roof R. This will be described below. In addition, as shown in FIG. 5, the greening base material A used in the illustrated example has attachment holes 11 formed at a predetermined pitch (P1, P2) in the X direction that is the roof gradient direction and the Y direction that is the eaves direction. The pitch P2 in the eaves direction is equal to or an integral multiple of the pitch Pa of the ridges 4 of the folded plate roof R. Accordingly, in the Y direction, which is the eaves direction of the folded plate roof R, the clamp 60 is fixed to the protrusion 4 that matches the pitch P2 of the mounting hole in the Y direction of the greening base material 10. A plurality of clamps 60 are fixed at an appropriate interval in the X direction, which is the roof gradient direction of the ridge 4 to which the clamps 60 are fixed.

  After fixing the required number of clamps 60 to the protrusions 4, the foamed resin heat insulating plate 40 is attached between the adjacent protrusions 4 and 4. At that time, as shown in FIG. 4, the first horizontal portion 62 b, the vertical portion 64, and the second horizontal portion 65 of each clamp piece 61 of the clamp 60 fixed to the both sides of the heat insulating plate 40 made of foam resin. It is made to insert in the U-shaped space formed in the section. Thereby, the upper surface of the standing folded plate roof R is entirely covered with the foamed resin heat insulating plate 40, and a flat surface is formed. In other words, the heat insulating plate 40 made of foamed resin used here has a lateral width in the eaves direction (Y direction) substantially equal to the distance between adjacent protrusions 4 and 4 to which the clamp 60 is fixed, and the thickness is The distance between the inner sides of the first horizontal portion 62b and the second horizontal portion 65 in the piece 61 is substantially equal. In addition, the length of the roof gradient direction (X direction) of the foamed resin heat insulating plate 40 is arbitrary.

  Next, on the pair of clamp pieces 61, 61 of the plurality of clamps 60 fixed to the ridge 4, the long pressing member 80 described above is in the X direction whose longitudinal direction is the roof gradient direction. By using the bolt hole 81 formed in the long pressing member 80 and the bolt hole 67 formed in the clamp piece 61, the long pressing member 80 is appropriately attached to the clamp 60 such as a bolt. It is fixed by the fixing means. Thereby, the foamed resin heat insulating plate 40 attached so as to be inserted into the U-shaped space of the clamp 60 fixed to the ridge 4 has all the side edges in the X direction which is the roof gradient direction. The long pressing member 80 is further pressed from above, and a stable mounting posture is obtained.

  As described above, the long pressing member 80 is provided with the required number of screw rods 70 functioning as struts at a predetermined interval. In this example, the pitch (interval) of the screw rods 70 is equal to the pitch P1 in the X direction that is the roof gradient direction of the mounting holes 11 formed in the greening base material A described above. The screw rods 70 may be fixedly erected on the long pressing member 80 in advance, or may be attached to the long pressing member 80 at a predetermined pitch at the construction site.

  In the example shown in FIG. 5, the greening base material A that is fixed to the standing folded plate roof R is configured by assembling a plurality of unit greening base materials 10 that are substantially square. The unit tree planting base material 10 is a molded product of foamed resin, and as shown in FIG. 4, the unit greening base material 10 has a water retention space 12 and a planting layer support 13, and the connecting wall uneven portion 14 is fitted to the peripheral wall portion. It is formed. A hole 11 is formed in each even portion, and when the adjacent unit greening base materials 10 and 10 are assembled using the connecting uneven portion 14, the mounting hole 11 communicates vertically. In this example, when a plurality of unit greening base materials 10 are assembled into a greening base material A, the mounting holes 11 are arranged at a pitch P1 in the X direction, which is the roof gradient direction, and in the eaves direction. In a certain Y direction, they are arranged at a pitch P2. The greening base material A may be made of a single piece, but even in that case, the attachment holes 11 are formed with the pitch P1 and the pitch P2.

  As shown in FIG. 4, the gap s caused by each clamp piece 61 of the clamp 60 is easily formed between the adjacent foam resin heat insulation plates 40 in a state where the foam resin heat insulation plates 40 are spread. The gap s has a narrow width and can be left as it is. However, when more complete heat insulation is desired, an appropriate heat insulating material such as a foamed resin heat insulating material is inserted into the gap s. Although not shown, the gap s can be eliminated by providing a notch in a portion corresponding to the position of each clamp piece 61 of the clamp 60 in the foamed resin heat insulating plate 40. In addition, when it is desired to more stably install the adjacent foam resin heat insulating plates 40, an appropriate connecting material such as an H-shaped joiner can be inserted into the gap s. Further, the long pressing member 80 is not simply a flat plate as shown in the figure, but also by using a T-shaped section having a vertical member that can enter the gap s, the gap can be reduced. Can be eliminated.

  After the long pressing member 80 is fixed as described above, the necessary number of unit greening base materials 10 are passed through the mounting hole 11 with the screw rod 70 erected on the long pressing member 80. It arrange | positions on the heat insulating board 40 made from a foamed resin. As shown in FIG. 4, by screwing a nut 73 into a screw rod 70 protruding from the unit greening base material 10, the unit greening base material 10 is firmly fixed on the folded plate roof R. By tightening all the unit greening base materials 10 with the nuts 73, as shown in FIGS. 4 and 5, the structure for fixing the greening base material to the folded plate roof according to the present invention is completed. As described above, in order to make the upper surface of the folded folded plate roof R flat, the plurality of foamed resin heat insulating plates 40 arranged thereon have a long overall length of the side edge in the X direction. The fixing structure according to the present invention is pressed by the scale-shaped pressing member 80, and exhibits high stability against negative pressure as a whole.

  Although not shown in the drawings, a foamed resin heat insulating plate 40 in which a root-proof sheet is laminated on its upper surface can also be used. In this configuration, when the folded plate roof greening structure is used, the foamed resin heat insulating plate 40 can be prevented from being damaged by the roots of the plant. The root-proof sheet is more preferably a water-impermeable sheet, and examples of the water-impermeable sheet include a sheet obtained by laminating polystyrene on a foamed polyethylene sheet.

  You may make it affix a nonwoven fabric to the back surface side of the heat insulating board 40 made of foamed resin. By attaching the nonwoven fabric, the strength against the mounting load of the foamed resin heat insulating plate 40 is increased, so that the workability when a person gets on the foamed resin heat insulating plate 40 and fixes the greening base material A is stabilized. It can be made.

  Further, as described above, when the unit greening base material 10 is fixed using the screw rod 70, a nut 73 is attached after attaching a large area pressing plate to the screw rod 70 protruding from the unit greening base material 10. The unit tree planting base material 10 may be fixed on the folded plate roof R while being screwed. By using such a large area pressing plate, a more stable fixing structure of the unit greening base material 10 can be obtained.

  FIG. 6 shows another form of the fixing structure. In this form, when the clamp pieces 61 and 61 are fixed to the standing protrusion 4, the clamp piece 61 that clamps the protrusion 4 and the protrusion 4. , 61 is interposed with a packing material 75. Examples of the packing material 75 include polystyrene resin foam, polyurethane resin foam, vinyl chloride resin foam, and the like. By adopting this configuration, when the rust prevention treatment of the protrusion 4 is peeled off, it is possible to effectively prevent the corrosion current due to the contact between the roof plate 1 and the clamp piece 61, which are usually different metals, from flowing. In addition, it is possible to prevent the fixing of the clamp 60 from becoming unstable due to corrosion of the standing edge portion over a long period of time. Moreover, the front-end | tip of the clamping front-end | tip parts 62a and 62a shown in FIG. 8 can be curved outward, and the surface which touches the protrusion 4 can also be made into a curved surface. By doing so, the clamp pieces 61 and 61 can be firmly fixed without damaging the protrusion 4 more.

  7 and 8 show an example of a standing folded-plate roof greening structure B made using the greening base material A fixed as described above. 7 is a view as seen from the side of the folded plate roof R, and FIG. 8 is a view seen from the eaves direction of the folded plate roof R. As shown in FIG. 7, the eaves parting material 50 is attached to the eaves of the folded plate roof R in the Y direction, and as shown in FIG. The side edge parting material 51 is attached in the X direction, that is, along the chevron 1. As shown in FIG. 4, a foamed resin heat insulating plate 40 is attached to the region partitioned by the parting materials 50 and 51 so that the folded plate roof R has a flat surface. 40 is stably attached to the roof surface by a long pressing member 80 disposed thereon, and further, a unit using a column (screw 70) standing on the long pressing member 80. The greening base material 10... Is stably fixed to be the greening base material A (in FIGS. 7 and 8, the clamp 60, the clamp piece 61, and the long pressing member 80 are not shown. Omitted). In addition, the above-mentioned root prevention sheet is arranged between the foamed resin heat insulating plate 40 and the greening base material A, and the foamed resin heat insulating plate 40 and the standing folded plate roof R are damaged by plant roots. Is preventing. Although not essential, a nonwoven fabric 53 having a rooting function is preferably laid on the fixed greening base material A, and the nonwoven fabric 53 stands on at least a long pressing member 80. It is partially fastened by the provided support column (screw rod 70). On top of that, an appropriate planting layer 54 is formed as is conventionally known. Preferably, although not shown, a soil blow prevention net is installed on the upper surface of the planting layer 54.

  When water is sprinkled from the top of the folded plate roof greening structure B constructed in this way, the water permeates the planting layer 54 and accumulates in the water retention space 12 of the greening base material A, and the water is the planting layer. 54 helps the plant 55 vegetated grow. Further, excess water including rainwater overflows the greening base material A and flows down.
