Description

  The present invention is a folded plate roof having a structure in which the mountain-shaped portions are continuous at a predetermined pitch, in particular, the ridges having roundness when the roof plates are connected are running in the roof gradient direction on the top of the mountain-shaped portions. The present invention relates to a fixing structure for stably fixing a greening base material to a so-called standing folded roof and a standing folded roof roof greening structure using the fixing structure.

Background art and problems

  A greening base material made of foamed resin or the like is fixed to a roof or a roof, and a planting mat or the like is laid thereon to green the roof. The greening base material has water retention and drainage properties, keeps rainwater or water supply, and gives water necessary for growth to plants on the planting mat. An example of such a greening base material is shown in Patent Documents 1 and 2 and the like. In the case of rooftop greening, it is necessary to stably fix the greening base material to a support base that is a roof or a rooftop. Therefore, as described in Patent Document 2, mounting holes are formed in the greening base material at a constant pitch in both the vertical and horizontal directions, and on the support base side, the pitch of the mounting holes is adjusted by an appropriate method. Thus, the bolt is fixedly fixed. A fixed structure of a greening base material in which a required number of greening base materials are laid on the roof or the roof with bolts passing through the mounting holes and fixed with nuts is widely used.

  If the roof or roof surface on which the greening base material is installed is flat, it is easy to fix the bolts in both the vertical and horizontal directions according to the pitch of the mounting holes of the greening base material. There is no particular problem with installation.

  However, as shown in FIG. 1, the folded plate roof, that is, the 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 mountain-shaped portion 1 At the top 2 of the roof, a green ridge 4 (running ridge) 4 having a roundness when the roof plate 3 is connected is running in the direction of the roof slope, and the greening base material is stably fixed on the folded plate roof. This is not easy for the following reasons.

  One of the reasons is that the standing folded plate roof, as shown in a cross section in FIG. 1b, is formed with a long portion in which curved portions 3a and 3b are formed at the upper ends of the left and right rising edges. While the curved roof plate 3 is engaged with the curved portions of the adjacent roof plates 3, 3, the roof plate 3 is fixed on the beam 5 using the dedicated attachment 6. This is because the ridges 4 that run in the roof gradient direction at a constant pitch Pa in the eaves direction are formed on the top of the part 2, but there are no bolts or the like for fixing the greening base material on the roof surface.

  In order to eliminate the inconvenience, in Patent Document 3, as shown in FIG. 13, a necessary number of fixtures 8 with bolts 7 are fixed to the ridges 4 by using screws 9 as shown in FIG. It is described that the bolt 7 is used to stand and fix the planting layer and the planting mat 54 to the folded plate roof. By using such an attachment 8, a bolt can be erected at an arbitrary position on the ridge 4. However, the fixture 8 has a shape in which the tip of the screw 9 is in contact with the lower part of the ridge (stand) 4 and is fastened and fixed. Therefore, a stable fixing mode cannot be obtained. Further, if the screw is tightened strongly, the ridge 4 will be damaged.

  Another inconvenience that arises when fixing the greening base material on the standing folded plate roof is that the pitches P1, P2 in the vertical and horizontal directions (the X and Y directions) of the mounting holes formed in the greening base material, It is difficult to match the pitches of the bolts 7 erected as described above in the X and Y directions. In the method described in Patent Document 3, the fixture 8 is arranged so that the pitch in the X direction matches the pitch P1 in the X direction of the attachment holes formed in the planting base material to be fixed in the X direction. By attaching to the ridge 4 (stands), it can be solved temporarily. However, it is not easy to measure the distance corresponding to the pitch P1 every time one attachment 8 is attached. In addition, the pitch in the Y direction of the ridges (stands) 4 and the pitch P2 in the lateral direction (Y direction) of the mounting holes formed in the greening base material are usually inconsistent. Even if such an attachment 8 is used, the greening base material cannot be stably attached on the folded plate roof.

  In general, greening base materials intended to be installed on the roof need to be light, and in many cases there is no problem as long as the compressive strength is satisfied. Therefore, it is designed to be as thin as possible and does not have a large bending strength. However, when fixing the greening base material on the folded plate roof using the attachment 8 as described in Patent Document 3, the greening base material is supported only by the area of the attachment 8. As a result, the bending strength may be insufficient.

The present invention has been made in view of the circumstances as described above, and a first object is to use a ridge which is a member that stands up a member such as a bolt used to fix a greening base material. It is to provide a structure for fixing the greening base material to the folded-plate roof so that it can stand up stably and stably. In addition, the second object of the present invention is to use ridges (standing up) regardless of the pitches P1 and P2 in the X and Y directions of the mounting holes formed in the greening base material. By using bolts that are erected, we provide a structure for fixing the greening base material to the folded plate roof that enables the greening base material to be stably mounted on the folded plate roof It is to be.

  In order to achieve the first object, the greening base material fixing structure to the folded plate roof is continuous at a predetermined pitch Pa in the Y direction, which is the eaves direction, with the chevron running in the X direction, which is the roof gradient direction. The mountain-shaped portion is a fixing structure for fixing the greening base material on the standing folded-plate roof where the protrusions when the roof boards are connected in the direction of the roof slope, A clamp composed of a pair of clamp pieces sandwiching the right and left sides is fixed to at least two portions of the ridge, and a long first fixing jig extending in the X direction is attached using the fixed clamp, The greening base material is fixed to the first fixing jig (claim 1).

  In the above-described fixing structure, a clamp comprising a pair of clamp pieces for sandwiching the ridge from the left and right is used as a clamp for fixing to the ridge which is a standing ridge formed on the standing folded plate roof. The protruding portion is sandwiched between the pair of clamp pieces, and the pair of clamp pieces is tightened by means such as screw tightening. Accordingly, the clamp is firmly fixed to the ridge portion in a posture in which a pair of left and right clamp pieces sandwiches both sides of the ridge. Since the tip of the tightening screw does not abut on the ridge, the ridge (stand-up) is not damaged. The long first fixing jig extending in the X direction is directly or directly attached to the clamp fixed in such a manner via the second fixing jig as described later. Since the greening base material is fixed to the fixing jig, in the structure for fixing the greening base material to the folded folded plate roof according to the present invention, a stable fixing state of the greening base material can be obtained.

  In this invention, the greening base material used by the conventional rooftop greening can be used arbitrarily as a greening base material. The material is preferably made of a foamed resin from the viewpoint of light weight and ease of molding, but may be made of a material such as a non-foamed resin or foamed mortar. The greening base material may have a form in which a greening base material such as a planting sheet is accommodated as it is, and is provided with a water retention and drainage function as described in Patent Document 1, and further, like a planting sheet. The thing of the form which mounts a greening base material. Further, the greening base material may be a single piece, or may be configured by combining a plurality of unit greening base materials.

  In order to achieve the second object of the present invention, the structure for fixing the greening base material to the folded plate roof is the above fixing structure, wherein the greening base material has its mounting holes pitched in the X direction. P1, which has a pitch P2 in the Y direction, and the first fixing jig is a long shape in which bolts are erected at the same pitch P1 as the pitch P1 in the X direction of the greening base material. It is a fixing jig, and the greening base material is fixed to the first fixing jig by using the bolt (claim 2).

  In the above fixing structure, when the pitch Pa in the Y direction of the ridges that are standing is equal to the pitch P2 in the Y direction of the mounting holes formed in the greening base material, or an integral multiple thereof becomes the pitch P2. The first fixing jig is fixed by fixing the clamp to a protrusion at a position corresponding to the pitch P2 of the mounting hole of the greening base material, and directly attaching the first fixing jig to the fixed clamp. Can be used to stably attach the greening base material.

  However, as described above, it is normal that an integral multiple of the pitch Pa in the Y direction of the protruding ridges does not coincide with the pitch P2 in the Y direction of the mounting holes of the greening base material. In another aspect of the structure for fixing the greening base material to the folded plate roof according to the present invention, the one end has a locking hole that can be engaged with the clamp fixed to the ridge with a degree of freedom. In addition, a second fixing jig that can be fixed to the first fixing jig at the other end is further used. And the greening base material is fixed using the bolt of the 1st fixing jig fixed to the 2nd fixing jig (Claim 3).

  In this way, the second fixing jig that can be engaged with the clamp fixed to the ridge with a degree of freedom is used, and the first fixing jig is fixed to the second fixing jig. By doing so, it becomes possible to fix the first fixing jig on the folded plate roof at an arbitrary pitch different from the pitch Pa in the Y direction of the protruding ridges. By fixing the first fixing jig so as to coincide with the pitch P2 in the Y direction of the mounting hole of the greening base material to be fixed, the greening base material is used by using the first fixing jig. It can be fixed securely.

  It is also possible to use a second fixing jig having a shape that allows the fixing position to be adjusted between the other end side and the first fixing jig. In this case, it is easier to adjust the pitch of the first fixing jig.

  In the structure for fixing a greening base material to the folded plate roof of the present invention, the clamp attached to the ridge and the second fixing jig may obstruct the laying of the greening base material. In order to avoid this, the present invention further provides a fixing structure for the above greening base material, wherein the raised folding plate roof is provided with a raising material, and the first fixing jig is It arrange | positions on the raising material, and the 2nd fixing jig fixes the other end to the clamp which fixed one end to the said protrusion in the location where the raising material is not arrange | positioned, and a 1st fixing jig. Also disclosed is a structure for fixing a greening base material to a folded-up folded-plate roof characterized by being fixed to a roof.

  In this fixing structure, since the greening base material is fixed using the first fixing jig arranged on the raising material, the clamp attached to the ridge and the second fixing jig are greened. It is possible to effectively avoid hitting the bottom surface of the base material. Furthermore, since the attachment state of the first fixing jig is also stabilized, the fixing of the greening base material itself is further stabilized.

  In the above aspect, the raising material may be any material that can ride on the ridge (stand) while avoiding the clamp fixed to the ridge (stand). May be a flat plate material having a large area. In this case, as the raising material, it is desirable to use a material made of foamed resin for the purpose of weight reduction. Specific examples include foamed polystyrene, foamed polypropylene, foamed polyethylene, foamed urethane, and foamed vinyl chloride. Instead of foamed resin, it may be made of non-foamed synthetic resin or wood.

  As the raising material, a panel material having a flat top surface obtained by bending a thin iron plate such as tin plate into a box shape, a square pipe made of resin or steel, a channel material, or the like can also be used. In this case, the raising material is arranged in a direction perpendicular to the roof slope direction of the folded plate roof. At that time, it is desirable to arrange the raising materials with a gap, and the second fixing jig is attached using the gap.

  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 (claim 6). The mode of vegetation planting may be the same as in the case of conventionally known rooftop greening. Although soil may be laid in the greening base material and plants may be grown there, a vegetation mode in which a conventionally known planting mat is laid on the greening base material is more preferable. In this 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 (Claim 7), and in that case, between the vegetation mat and the vegetation base material. Preferably, a ventilation space is formed.

  Moreover, it is also a preferable aspect that a non-woven fabric is laid on the upper surface of the vegetation base material and has a rooting function there. Thereby, it can prevent that the root of a plant reaches a roofboard, and can prevent the unnecessary damage of a roofboard. It is also possible to prevent damage to the roof by laying a sheet having such a rooting function on the lower surface of the greening base material.

  In another aspect of the standing folded-plate roof greening structure according to the present invention, a net is hung on the planting mat, and the net is fastened by using a bolt attached to the first fixing jig. (Claim 8). By placing a net on the planting mat, it is possible to prevent the plant and soil from being scattered by wind etc., and even if the plant is stable and difficult to fix by planting with thin soil, it is stable The fixed effect is obtained. Furthermore, by fastening the net using bolts, the net is prevented from being scattered and the stability of the standing folded plate roof greening structure is improved.

  In the above description, the direction perpendicular to the Y direction which is the eaves direction is expressed as the X direction as the roof gradient direction, but in the present invention, it is not essential that the roof has a gradient in the X direction. In view of the essence of the invention, the roof may be a folded-plate roof, and even if it is a horizontal roof without a slope, it is included in the scope of the present invention.

  According to the present invention, a member such as a bolt used for fixing a greening base material can be stably erected by using a protruding ridge. Moreover, whatever the pitches P1 and P2 in the X direction and the Y direction of the mounting holes formed in the greening base material are, using bolts erected using the ridges (standing up) Standing can be stably mounted on a folded roof. For this purpose, a rooftop greening structure with a stable structure can be built 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 standing folded plate roof, and FIG. 2 shows a clamp that is fixed to a ridge that is standing. FIG. 3 is a plan view showing the greening base material fixed on the standing folded-plate roof. FIG. 4 shows a first fixing jig used in the fixing structure of the present invention, and FIG. 5 shows a second fixing jig. FIG. 6 is a view for explaining one embodiment of the fixing structure of the greening base material according to the present invention, and FIGS. 7 to 9 are standing views made using the greening base material fixed by the fixing structure shown in FIG. The folded-plate roof greening structure is shown. 10 and 11 are views for explaining another embodiment of the greening base material fixing structure according to the present invention.

  In addition, as shown in FIG. 1, the standing folded plate roof R has a mountain-shaped portion 1 that runs in the X direction that is the roof gradient direction and is continuous at a predetermined pitch Pa in the Y direction that is the eaves direction. At the top 2 of the part 1, a ridge 4 (standing up) 4 having a roundness when the roofing plates 3 are connected runs in the roof gradient direction. The greening base material 10 (see FIG. 3) is fixed on such a standing folded-plate roof R to obtain a standing folded-plate roof greening structure according to the present invention.

  FIG. 2 shows the clamp 60 used therein. The clamp 60 includes a pair of left and right clamp pieces 61 and 61 having a certain lateral width. Each clamp piece 61 is in a vertical position substantially the same as the front end position of the sandwiching front end portion 62, a squeezing front end portion 62 that presses down the lower region of the protruding ridge 4 that is standing, It has a vertical part 64 and a horizontal part 65 located at the upper end of the vertical part 64, and the vertical part 64 is formed with a bolt hole 66 for a bolt used when fastening the left and right clamp pieces 61, 61 together. Has been. The horizontal portion 65 is also formed with a bolt hole 67 for a bolt used when fixing other members together. Note that the bolt holes 66 and 67 can be omitted when fixing with a drill screw without using a bolt and nut.

  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 may be such that when the left and right clamp pieces 61, 61 are tightened, the inner peripheral surface thereof partially contacts the protrusion 4.

  When fixing the clamp 60, the ridge 4 is sandwiched between the bulging portions 63 of the left and right clamp pieces 61, 61, and bolts 66 formed in both vertical portions 64 are tightened with nuts through a bottle. 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 greening base material 10 is fixed using the clamp 60 thus fixed. Although not shown in the drawings, a plurality of clamps 60 are fixed to the necessary portions of the protruding ridge 4 that is standing, and bolts are erected using bolt holes 67 formed in the horizontal portion 65 of the fixed clamp 60, The greening base material 10 can also be fixed directly to the bolt. However, as described above, the greening base material 10 is usually provided with the attachment holes 11 at a predetermined pitch (P1, P2) in the X direction which is the roof gradient direction and the Y direction which is the eaves direction. It is extremely difficult to fix a large number of clamps 60 on each protrusion 4 so as to coincide with the pitches P1 and P2, and it may be impossible in the Y direction.

  In the following embodiment, the pitch adjustment in the X direction is facilitated by using the first fixing jig 20 (FIG. 4), and the Y direction is achieved by using the second fixing jig 30 (FIG. 5). It is possible to easily and arbitrarily adjust the pitch. In addition, when the integral multiple of the pitch Pa of the protrusion 4 in the Y direction matches the pitch P2 of the greening base material 10 in the Y direction, the use of the second fixing jig 30 can be omitted.

  In this example, as shown in FIG. 3, the greening base material A fixed to the standing folded-plate roof R is constructed 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, has a water retention space 12 and a planting mat support 13, and a connecting uneven portion 14 is formed on the peripheral wall portion. A hole 11 is formed in each even portion, and the hole 11 is connected to the mounting hole 11 that communicates vertically when the adjacent unit greening base materials 10 and 10 are assembled using the connecting uneven portion 14. Become. 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 pitch P1 and the pitch P2 may be the same or different. 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. FIG. 3 also shows the first fixing jig 20 described above.

  As shown in FIG. 4, the first fixing jig 20 includes a long metal plate 21 and a plurality of bolts 22 fixedly standing on the metal plate 21, and an interval (pitch) between the bolts 22 is set. The pitch P1 is the same as the pitch P1 in the X direction which is the roof gradient direction of the mounting holes 11 formed in the greening base material A. Further, as will be described later, a hole 23 used for fixing the other end side of the second fixing jig 30 and the bolt nuts 25 and 26 (FIG. 6) is formed at a required portion. In addition, when fixing using a drill screw, without using the bolt nuts 25 and 26, the hole 23 can be abbreviate | omitted.

  As shown in FIG. 5, the second fixing jig 30 is a long metal plate 31, and long holes 32 are formed at both ends thereof. In addition, when fixing using a drill screw without using a bolt nut, the long hole 32 can be abbreviate | omitted. Depending on the form of the fixing structure, the flat plate-like second fixing jig 30a shown in FIG. 5a and the second fixing jig shown in FIG. The tool 30b is selectively used. Further, the second fixing jig 30c having a shorter length may be used as shown in FIG.

  In the construction, as described with reference to FIG. 2, the first fixing jig 20 is attached to the protrusion 4 which is the standing portion of the one mountain-shaped portion 1 of the standing folded plate roof R. The clamp 60 is fixed at the pitch of the holes 23 formed. The clamp 60 is similarly fixed to the chevron part 1 adjacent to the chevron part 1, which is located at a position substantially coinciding with the pitch P <b> 2 in the Y direction of the greening base material 10.

  Next, as shown in FIG. 6, a foamed resin plate 40 having an opening 41 capable of avoiding the fixed clamp 60 is laid on the ridge 4 that is standing as a raising material. The thickness of the foamed resin plate 40 is set to a thickness exceeding the height of the clamp 60 fixed to the protrusion 4. The shape and size of the foamed resin plate 40 in a plan view are arbitrary, and a plurality of foamed resin plates 40 are gathered together so as to cover the required area on the folded plate roof R. Also good.

  The required number of first fixing jigs 20 are temporarily arranged in the X direction on the foamed resin plate 40 spread and in the vicinity of the clamp 60 fixed to the protrusion 4. Next, one end portion of the flat plate-like second fixing jig 30a shown in FIG. 5a is provided with a long hole 32 formed therein and a bolt hole 67 formed in the horizontal portion 65 of the clamp 60 already fixed. The nut 69 is temporarily tightened through the fixing bolt 68 to be temporarily fixed to the clamp 60 side.

  Further, a bolt 25 is passed through a long hole 32 formed in the other end of the temporarily fixed second fixing jig 30a and a hole 23 formed in the first fixing jig 20, and a nut 26 is attached. By temporarily tightening, the second fixing jig 30a and the first fixing jig 20 are temporarily fixed. The same thing is performed between the other clamps 60 fixed to the ridges 4 on the same chevron 1 and the first and second fixing jigs 20 and 30. In FIG. 6, the first fixing jig 20 is disposed below the second fixing jig 30a. However, the first fixing jig 20 is disposed above the second fixing jig 30a. May be arranged.

  In this state, the first fixing jig 20 can slightly move in both directions of the X direction and the Y direction, so that the first fixing jig 20 is in a predetermined position according to the design specifications at the construction site. The jig 20 is positioned, and the nut 69 on the fixing bolt 68 side and the nut 26 on the bolt 25 side are tightened to fix the position of the first fixing jig 20. In addition, when required alignment can be performed only with the long hole 32 engaged with the fixing bolt 68, the long hole 32 on the other end side of the second fixing jig 30a may be a circular hole.

  In this aspect, since the back side of the greening base material A (unit greening base material 10) must avoid contact with the second fixing jig 30 and the first fixing jig 20, the member is A recessed portion 19 is formed on the back surface of the greening base material A (unit greening base material 10) to be positioned.

  Positioning and fixing are performed in the same manner for the second first fixing jig 20 located on the side. At that time, the interval between the reference first fixing jig 20 and the second first fixing jig 20 is in the Y direction, which is the eaves direction of the attachment hole 11 formed in the greening base material A. The second first fixing jig 20 is positioned so as to be the same as the pitch P2. As described above, this position adjustment is possible because the second fixing jig 30a has the long holes 32 as the locking holes at both ends, and the difference in pitch can be absorbed there.

  The necessary number of first fixing jigs 20 are similarly fixed to the mountain-shaped portion 1 of the folded plate roof R (the protruding ridge 4 that is standing) to lay the foamed resin. On the plate 40, a required number of bolts 22 are fixedly erected at a pitch P1 in the X direction and at a pitch P2 in the Y direction (see also FIG. 3).

  The required number of unit greening base materials 10 are arranged on the foamed resin plate 40 while the bolts 22 are passed through the mounting holes 11 formed in the unit greening base material 10 using the standing bolts 22. . By screwing the nut 28 into the bolt 22 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 28, the greening base material A fixed by the fixing structure according to the present invention stands on the folded plate roof R as shown in FIG. Complete.

  FIGS. 7-9 shows the standing folded board roof greening structure B made using the greening base material A fixed using the fixing structure shown in FIG. 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. 9a is a view seen from the eaves direction of the folded plate roof R in which the fixing structure portion appears, and FIG. 9b shows the first fixing jig 20 and the second fixing jig 20 shown in FIG. 9a. Only the part of the fixing structure with the fixing jig 30 is shown from above. 7-9, the same code | symbol is attached | subjected to the same member as the member shown in FIG. 6, and description about fixing structure is abbreviate | omitted.

  As shown in FIG. 7, the eaves edge 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. In the region defined by the parting materials 50 and 51, the foamed resin plate 40 as the raising material is laid as described above, and the first fixing jig 20 and the second fixing jig are formed thereon. The unit greening base material 10... Is fixed using 30 to be the greening base material A.

  As shown in FIG. 9b, in this example, the second fixing jigs 30a and 30c having different lengths shown in FIGS. 5a and 5c are used. On the right side of the figure, the first fixing jig is used. The second fixing jig 30a having a long length is used to fix the tool 20, and the second fixing jig 30c having a short length is used to fix the first fixing jig 20 on the left side. ing. In this way, the lengths of different lengths depend on the relationship between the pitch Pa of the mountain-shaped portion 1 of the folded plate roof R (the protruding ridge 4 that is standing) and the pitch P2 of the greening base material A in the Y direction. 2 fixing jigs may be used.

  In the example shown in the drawing, when assembling the standing folded-plate roof greening structure B, a rooting sheet 52 is laid between the foamed resin board 40 as the raising material and the greening base material A, The foamed resin plate 40 and the standing folded plate roof R are prevented from being damaged. In addition, a non-woven fabric 53 preferably having a rooting function for preventing soil outflow is laid on the fixed greening base material A, and an appropriate conventionally known planting mat 54 is disposed thereon. . Although not shown, it is desirable to install a soil blow-off prevention net on the upper surface of the planting mat 54, and by fixing the net with the bolts 22 used for fixing the greening base material A, the standing plate roof greening is standing. The entire structure B can be stabilized.

  When water is sprinkled from above the standing folded-plate roof greening structure B constructed as described above, the water permeates the planting mat 54 and accumulates in the water retention space 12 of the greening base material A, and the water is stored in the planting mat. 54 helps the plant 55 vegetated grow. Further, excess water including rainwater overflows the greening base material A and flows down.

  Although not shown in the drawings, a water uptake material may be placed in each unit greening base material 10 like a sponge in contact with the lower surface of the planting mat 54. In this case, water in the bottom of the water retention space 12 is placed. There is an advantage that can be sucked toward the planting mat 54.

  FIG. 10 shows a second embodiment of the fixing structure according to the present invention. Here, not the foamed resin plate 40 but a steel square pipe 40A is used as the raising material. The height of the square pipe 40A is higher than the height of the clamp 60 fixed to the angled portion 1 of the standing folded plate roof R, and the necessary number of square pipes 40A are arranged in the Y direction so as to avoid the clamp 60. Are arranged in parallel with each other at a required interval. As the second fixing jig 30, the second fixing jig 30b having different heights at both ends shown in FIG. 5b is used, one end thereof is fixed to the clamp 60, and the other end is connected to the first fixing jig 30b. It is fixed to the fixing jig 20. The first fixing jig 20 is provisionally arranged using the upper surface of the arranged square pipe 40A as a support base. Hereinafter, the first fixing jig 20 temporarily arranged in the same manner as shown in FIG. Is fixed at a predetermined position with respect to the clamp 60. In addition, the same code | symbol is attached | subjected to the member which show | plays the same function, The description is abbreviate | omitted.
