Description

  The present invention relates to a rooftop greening system for folded plate roofs that can be easily installed.

  Conventionally, the roof of a building has been greened, and various greening systems have been proposed. There are various rooftop shapes, for example, there is a folded plate roof in which convex portions and concave portions are alternately positioned and extend linearly. As shown in FIG. 4, the greening system for the folded-plate roof bridges the tops of the respective convex portions by fixing the support members 34 to the tops of the convex portions 32 of the folded-plate roof 30 with bolts or the like. A planting mat 36 and the like are laid on a cross-linked support member (see Patent Document 1).

JP 2006-25768 A

  However, the operation | work which fixes a support member to the top part of the convex part of a folded-plate roof with a volt | bolt in this way is complicated. Then, an object of this invention is to provide the rooftop greening system for folded-plate roofs which can be easily installed in a folded-plate roof.

  In order to achieve the above-described object, the present invention provides a folding apparatus in which convex portions and concave portions are alternately positioned and linearly extend, and are installed on a folded plate roof having a protruding portion at the top of the convex portion. In the rooftop greening system for plate roofs, a first planting mat laid on the folded plate roof by inserting the protrusion from the bottom, and a second planting mat laid on the first planting mat The first planting mat is composed of a thermoplastic resin, and a bottom surface is coated with a synthetic resin different from the thermoplastic resin, and two or more first planting mats formed into a planar rectangular shape. The second planting mat is formed by juxtaposing planting mat members, and the second planting mat is made of a thermoplastic resin, and the first planting mat includes two or more second planting mat members formed in a planar rectangular shape. To make members and long sides cross and to be placed side by side Formed I, characterized in that said heat sealed at least a portion of the contact surface of the second planting mat member.

  As described above, according to the roof greening system for folded plate roofs according to the present invention, the first planting mat is laid directly on the folded plate roof without interposing the support members, so the support members are folded plates. The roof greening system can be easily installed on the folded-plate roof without requiring the work of fixing with bolts to the top of the convex portion of the roof. Moreover, according to the roof greening system for folded-plate roofs which concerns on this invention, coating is given to the bottom face of the 1st planting mat member which forms the 1st planting mat, and the 1st planting mat member and the 2nd Since the planting mat members are laid so as to cross each other, the strength can be sufficiently maintained even if the planting mat members are directly installed on the folded plate roof without providing the support members.

  In the roof greening system for folded plate roofs according to the present invention, the first planting mat member and the second planting mat member are preferably made of a nonwoven fabric containing polyester and a low-melting polyester as raw materials, and the coating Preferably has a root-preventing action, and preferably uses polyethylene as a main raw material.

  As described above, according to the present invention, it is possible to provide a roof greening system for a folded plate roof that can be easily installed on the folded plate roof.

  Next, the Example of the rooftop greening system for folded-plate roofs which concerns on this invention is described based on drawing. FIG. 1 is a front cross-sectional view showing a state in which the folded roof rooftop greening system according to the present embodiment is installed on the folded roof, and FIG. 2 is a plan view of the folded roof rooftop greening system according to the present embodiment. FIG. 3 is a perspective view showing a state in which the rooftop greening system for folded plate roof according to the present embodiment is installed on the folded plate roof.

  As shown in FIG. 1, the folded roof rooftop greening system according to the present embodiment is laid on a first planting mat 12 that is directly laid on the folded plate roof 10 and on the first planting mat 12. A second planting mat 14, and soil 16 is laid on the second planting mat 14.

  The first planting mat 12 is formed by arranging two or more first planting mat members 18 formed in a planar rectangular shape in parallel. The first planting mat member 18 is composed of a non-woven fabric (trade name: protector surface, manufactured by Shimizu Felt Kogyo Co., Ltd.) containing a thermoplastic resin such as polyester and low-melting polyester as a raw material. A manufactured root-proof sheet 20 is coated. The length of the long side 18A of the first planting mat member 18 is sufficiently longer than the interval between the convex portions 10A of the folded plate roof. The 1st planting mat member 18 was formed in the top part of convex part 10A of folded-plate roof 10 on the bottom face 18B, making the long side 18A intersect perpendicularly with respect to the extending direction of convex part 10A. By inserting the protruding portion 22 such as a screw, it is laid on the folded plate roof 10. In addition, when the protrusion parts 22, such as a screw, are not formed in the top part of 10 A of convex parts of the folded-plate roof 10, it carries out by attaching separately. Further, the protrusion 22 is inserted into the bottom surface 18B of the first planting mat member 18 by pressing the bottom surface 18B of the first planting mat member 18 against the protrusion 22.

  The second planting mat 14 is formed by arranging two or more second planting mat members 24 formed in a planar rectangular shape in parallel. The 2nd planting mat member 24 is comprised from the thermoplastic resin similar to the 1st planting mat member 18, and is formed in the same shape, However The root prevention sheet is not coated by the bottom face. The second planting mat member 24 is laid such that the first planting mat member 18 laid as shown in FIGS. 1 to 3 and the long sides 18A, 24A intersect perpendicularly. Parallel up. The second planting mat members 24 arranged in parallel are fixed by melting the contact portions with a burner or the like and heat-sealing them.

  According to the roof greening system for folded plate roofs according to the present embodiment, the bottom surface of the first planting mat member 18 forming the first planting mat 12 is coated, and the first planting mat member 18 and Since the second planting mat member 24 is laid in an intersecting manner, the strength can be sufficiently maintained even if the second planting mat member 24 is installed directly on the folded plate roof without providing a support member. Moreover, since the 2nd planting mat member 24 is heat-sealed, it does not flutter by a wind etc. Furthermore, the coating of the bottom surface 18B of the first planting mat member 18 can prevent water from evaporating from the bottom surface of the greening system, and can prevent drying from the bottom surface of the greening system.

It is front sectional drawing which shows the state which installed the Example of the roof greening system for folded-plate roofs concerning this invention in the folded-plate roof. It is a top view of the roof greening system for folded-plate roof which concerns on a present Example. It is a perspective view which shows the state which installed the roof greening system for folded-plate roofs concerning a present Example in the folded-plate roof. It is front sectional drawing which shows the state which installed the conventional greening system for folded-plate roofs in the folded-plate roof.
