  In rooftop greening, fixing water retention drainage base materials and parting materials to the roof surface is a particularly important issue in Japan where strong winds are blown by typhoons. On the other hand, ease of construction is also required. In the device described in Patent Document 1, the attachment 8a is attached to the protruding ridge, and the vegetation layer 54 and the parting material are fixed by using the attachment 8a. The attachment 8a stands the tip of the screw 8b. The screw 8b has a shape to be fixed by being brought into contact with the lower portion of the helical protrusion 4, and since the ground contact area of the tip of the screw 8b is small (substantially point contact), a stable fixing mode cannot be obtained and the screw is strongly tightened. If tightened, standing ridge 4 may be damaged. Further, the parting material is fixed to the edge of the mesh member 9 by welding or the like, and it takes time and labor for the work at the site, and the workability is not sufficient.

  The one described in Patent Document 2 is a structure in which a greening unit or a parting material is fixed to a bar fixed on a folded roof with an adhesive or tape, and has sufficient strength against negative pressure generated in a strong wind. There is a question whether to prepare.

  The present invention has been made in view of the circumstances as described above. A parting material surrounding an outer edge portion of a water retention drainage base material or the like disposed on a standing folded plate roof is provided. It is an object of the present invention to provide a parting material fixing structure that can be stably fixed to a helical protrusion.

  The present invention is a structure for fixing a parting material that surrounds an outer edge portion of a water retention drainage base material or the like arranged on a standing folded plate roof to the folded plate roof, in a position where the parting material should be fixed A clamp is fixed to the standing ridge so that the standing ridge is sandwiched from the left and right by a pair of clamp pieces, and the fixed clamp includes a parting material support, The parting material is fixed by using a parting material support.

  In the above fixing structure, the clamp is composed of a pair of clamp pieces that sandwich the standing ridge from the left and right, and the contact surface between the standing ridge and the clamp piece is not a point contact but a line or surface. As a result of the contact, the clamp is firmly fixed to the standing ridge portion, and the standing ridge formed on the folded plate roof is not damaged. Furthermore, since the parting material support is provided in the firmly fixed clamp and the parting material is fixed using the parting material support, the fixing of the parting material to the folded plate roof is extremely stable. At the same time, the work of fixing the parting material on site is also simplified.

  In the fixing structure of a parting material according to the present invention, a specific mode of providing the parting material support to the clamp is arbitrary, but one clamp piece as a clamp used for fixing the parting material in the roof gradient direction The form in which the parting material support in the direction along the ridge is integrally formed, and the parting material in the roof gradient direction is fixed using the integrally formed parting material support is From the viewpoint of both ease of use and high stability, it is extremely preferable.

  In the parting material fixing structure according to the present invention, the parting material having an L-shaped bent part on the lower end side is used as the parting material, and the L-shaped bent part is in the standing state in a state of being fixed to a clamp. A posture that enters the side of the water retention drainage base material placed on the folded plate roof secures the water retention drainage base material and the foamed resin insulation board placed under it more stably if necessary. More preferably.

  In the fixing structure for a parting material according to the present invention, the clamp has an engaging portion for a foamed resin heat insulating plate attached to the roof surface so that the upper surface of the folded plate roof becomes a flat surface. The water retaining drainage base material is disposed on the foamed resin heat insulating plate attached using the locking portion, and the foamed resin heat insulating plate and the parting material with respect to the clamp It is also a preferable aspect to adopt a structure in which the water retention / drainage base material is fixed integrally. By adopting this fixing structure, sufficient strength against negative pressure can be ensured for the entire greening structure constructed on the folded plate roof.

  In the parting material fixing structure according to the present invention, a material such as aluminum, stainless steel, or plastic can be used for the parting material. An aluminum parting material is particularly preferred because it is lightweight and has good workability.

  As the water retention drainage base material disposed on the standing folded plate roof, the water retention drainage base material used in the conventional rooftop greening can be arbitrarily used. 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 water retention drainage base material may be in a form that directly accommodates a planting layer composed of a guest soil layer or the like, or may have a form of having a water retention drainage function and placing a planting layer thereon. Further, the water retention / drainage base material may be a single material, or may be configured by combining a plurality of water retention / drainage base materials.

  According to the present invention, it is possible to fix the parting material on the standing folded roof with high stability. As a result, the roof greening structure having a stable structure can be fixed on the folded roof. Can be built on top of.

  Hereinafter, the present invention will be described based on embodiments with reference to the drawings.
