  DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

[1] Roof greening structure <1> Basic configuration The roof greening structure of the present invention greens the upper surface of a folded plate roof in which convex portions and concave portions are continuously formed.
The roof greening structure of the present invention is configured by fixing a plurality of rail members 2 in parallel on a folded plate roof 5 by a fixing bracket 1 and placing a greening base 3 between the rail members 2 (FIG. 1). .
Plants 4 are vegetated on the upper surface of the greening base 3. And the greening base | substrate 3 is fixed on the rail material 2 with the pressing metal fitting 5 attached to the fixing metal fitting 1 (FIG. 2).
In the Example of this application, although the upper surface of the folded-plate roof 6 which has the goby part 62 in the mountain part 61 is greened, the shape of the folded-plate roof 6 is not limited to this.
In some cases, an anti-scattering net (not shown) is further laid on the upper surface of the greening base 3 and fixed by the presser fitting 5.

<2> Fixing bracket The fixing bracket 1 is a member attached to the peak portion 61 of the folded plate roof 6, and includes an attachment portion 11 attached to the peak portion 61 and a bolt portion 12 fixed to the upper portion of the attachment portion 11 ( FIG. 3).
In the embodiment of the present application, the fixing furniture 1 is fixed by holding the goby portion 62 with the attachment portion 11 of the fixing bracket 1.
The fixing bracket 1 is also provided on the adjacent mountain portion 61. In addition, the fixtures 1 are arranged side by side at a predetermined interval in the flow direction of the folded roof 6.

<3> Rail material The rail material 2 is a long member juxtaposed on the folded plate roof 6 upper part.
The rail member 2 is formed into a substantially hat-shaped cross section by a top portion 21, a step portion 22 provided perpendicularly to both ends of the top portion 21, and a flange portion 23 provided horizontally at the lower end of the step portion 22 (FIG. 4). . By making the cross section into a substantially hat shape, the strength of the rail material 2 is increased.
A bolt insertion hole 24 is formed in the top portion 21.

<3-1> Arrangement of Rail Material The rail material 2 is provided on a mountain 61 that is parallel to the folded plate roof 6 and arranged in a direction perpendicular to the flow direction of the folded plate roof 6 (FIG. 1).
The rail member 2 is supported by the fixing bracket 1 by inserting the bolt portion 12 of the fixing bracket 1 through the bolt insertion hole 24 of the top portion 21. At this time, the attachment portion 11 of the fixing bracket 1 is included in a space defined by the top portion 21 and the two step portions 22 of the rail material 2 (FIG. 2).

<4> Greening base The greening base 3 is arranged side by side between the adjacent rail members 2 arranged.
The greening base 3 is a rectangular plate made of porous ceramics.
Porous ceramics are excellent in water retention, and can grow plants 4 on the surface. The plant 4 is preferably turf, sedum, moss or the like.
Since the porous ceramics are lightweight, the greening base 3 is easy to dispose.

<4-1> Arrangement of Greening Bases The greening bases 3 are arranged side by side between the adjacent rail members 2, but the side surfaces of the greening bases 3 correspond to the step portions 22 of the rail members 2, and both ends of the greening bases 3. The part is placed on the flange part 23 of the rail material 2.
By making the height of the greening base 3 substantially the same as the height of the step portion 22 of the rail material 2, the top portion 21 of the rail material 2 and the top surface of the greening base 3 become substantially the same plane.
Since the greening base 3 is placed on the flange 23 of the rail member 2, the center of gravity of the greening base 3 is located between the adjacent rail members 2, so that the rail member 2, the fixing bracket 1 and the folded plate roof can be used in an earthquake or a strong wind. Such force can be reduced.

<5> Holding metal fitting The holding metal fitting 5 is a square flat plate-shaped member (FIG. 5).
The pressing metal 5 forms a bolt hole 51 in the center.
The length of one side of the pressing metal 5 is made larger than the width of the top portion 21 of the rail material 2.
The four corners of the presser fitting 5 are folded downward to form convex pieces 52.

<5-1> Fixing with holding metal The holding metal 5 is inserted with the bolt part 12 of the fixing metal 1 into the bolt hole 51 with the greening base 3 arranged, and the nut 13 is inserted into the bolt part 12 from above the holding metal 5. Then, the holding metal fitting 5 and the rail material 2 and the greening base 3 located below the metal fitting 5 are fixed by the nut 13.
Further, the presser fitting 5 is pressed against the rail material 2 and the greening base 3 by the nut 13, but the convex piece 52 folded downward penetrates into the greening base 3 and prevents blowing up by the wind.

[2] Construction method of roof greening structure Next, a construction method of the greening structure of the folded-plate roof will be described.

<1> Arrangement of fixing brackets The fixing brackets 1 are mounted side by side on the mountain 61 of the folded roof 6. The interval between the fixing brackets 1 attached to the same peak portion 61 is substantially the same as the width of the greening base 3 (substantially the same as the length obtained by adding the width of the greening base 3 and the width of the top portion 21 of the rail material 2).
Since the fixing bracket 1 can be positioned at a predetermined interval along the peak portion 61, it can be installed in accordance with the width of the greening base 3, and the greening base 3 having various widths can be applied. By using the greening base 3 having a large width (long in the flow direction), the interval between the rail members 2 is increased, the number of the rail members 2 and the fixtures 1 can be reduced, and the construction period can be shortened.

<2> Installation of Rail Material Next, the plurality of rail materials 2 are placed on the mountain portions 61 on which the folded plate roof 6 is arranged in parallel, and are arranged perpendicular to the flow direction.
The rail member 2 is supported by the fixing bracket 1 by inserting the bolt portion 12 of the fixing bracket 1 through the bolt insertion hole 24 of the top portion 21.
Since the fixtures 1 are arranged at substantially the same interval as the width of the greening base 3, the rail member 2 is also at the same interval as the width of the greening base 3.
Since the rail member 2 has a substantially hat-shaped cross section, the strength is increased, the number of the fixtures 1 that support the rail member 2 can be reduced, and the construction period can be shortened.

<3> Installation of Greening Base After arranging a plurality of rail members 2, a plurality of greening bases 3 are installed between the step portions 22 of the adjacent rail members 2. Since the greening base 3 is made of porous ceramics, it is lightweight and can be easily installed.
Since the interval of the rail material 2 is substantially the same as the width of the greening base 3, the side surface of the rectangular greening base 3 corresponds to the stepped portion 22 of the rail material 2, and the end lower surface corresponds to the flange 23. For this reason, since the gravity center of the greening base 3 is between the adjacent rail members 2, it is possible to reduce the force applied to the rail member 2, the fixing bracket 1, and the folded plate roof during an earthquake or a strong wind.
And the plant 4 is vegetated on the upper surface of the greening base 3.

<4> Fixing by holding metal fittings The railing material 2 and the greening base 3 are fixed by inserting the holding metal fittings 5 into the bolt parts 12 of the fixing metal fittings 1, screwing nuts 13 into the bolt parts 12 and pushing down the holding metal fittings 5. To do.
By determining the length of the greening base 3 so that the corners of the greening base 3 are positioned below the presser bracket, a maximum of four greening bases 3 can be fixed by one presser bracket 5.
In addition, when only the diagonal corners of the greening base 3 are pressed down, the number of pressing metal fittings 5 can be reduced.

[Other Examples]
<1> Arrangement of Water Retaining Sheet A water retaining sheet 7 may be laid on the top surface of the top portion 21 of the rail material 2 (FIG. 6). At this time, the height of the greening base 3 is set to be substantially the same as the height of the upper surface of the water retaining sheet 7 laid, not the height of the rail material 2. Thereby, the upper surface of the greening base | substrate 3 and the upper surface of the water retention sheet | seat 7 become a substantially identical plane.
Then, the plant 4 is vegetated on the entire upper surface of the greening base 3 and the water retaining sheet 7.
Since the plant 4 can be vegetated on the entire upper surface of the greening base 3 and the upper surface of the water retaining sheet 7 positioned on the rail material 2, a large greening area can be secured in the roof structure.

<2> Greening tray In the above embodiment, a porous ceramic plate was used as the greening base 3, but it was constituted by a tray 31 having an open upper surface and a base material 32 such as soil disposed in the tray 31. The plant 4 may be vegetated on the base material 32 in the tray 31 (FIG. 7).
