  As described in Patent Document 1, it is necessary to accommodate a heat shielding material, a greening base material, a lid net, and the like, which are materials necessary for greening, in a container fixed to a folded-plate roof to obtain a greening base material. There is an advantage that the construction can be facilitated, and the construction can be facilitated. However, if the greening structure described in Patent Document 1 is applied to the greening structure of a standing folded plate roof as described in Patent Document 2, the load of the greening structure is a mountain shape of the standing folded plate roof. It will be supported only by the tops of the ridges (stands) formed on the tops of the parts, and the containers made of wire mesh or the like are likely to be deformed. Therefore, it is necessary to give the container a high strength by making the wire mesh stitch fine or using a wire having a large diameter, and the cost for the container increases. On the other hand, in the greening structure described in Patent Document 2, a foamed resin heat insulating plate is attached using a clamp fixed to a standing ridge, and the folded roof surface is made flat, and the greening base material is placed thereon. Since it is fixed, the stabilization of the greening base material can be ensured, but it is necessary to arrange a foamed resin heat insulating plate to make the folded plate roof surface flat, and the construction is somewhat complicated It has become.

  The present invention has been made in view of the above circumstances, and in a fixing structure for fixing a greening base material on a folded plate roof, stable installation of the greening base material while being easy to construct. It is an object of the present invention to disclose a fixing structure capable of obtaining a posture.

  According to the present invention, the fixing structure for fixing the greening base material on the mountain-shaped portion of the standing folded plate roof is one or two in the direction orthogonal to the roof slope direction using the top of the standing protruding ridge. The first rod member described above is attached, and the greening base material is perpendicular to the first concave groove and the first concave groove in which the standing ridges enter the back surface, and the first rod member is The green base material has the standing protrusion inserted into the first groove and the first rod member inserted into the second groove. And it is characterized by being fixed to the folded-plate roof surface in a state where a part of the back surface is in contact with the horizontal top surface of the mountain-shaped portion of the folded-plate roof.

  In the fixing structure described above, the greening base material is fixed to the folded-plate roof surface in a state where its back surface is in contact with the horizontal top surface of the mountain-shaped portion of the folded-plate roof, and its mounting posture is extremely stable. Become posture. Moreover, the greening base material made the 1st rod member attached in the direction orthogonal to a roof gradient direction using the top part of a standing ridge protruding into the 2nd ditch | groove formed in the back surface. Standing in a posture, it is fixed to the folded-plate roof surface, and it is possible to reliably prevent the greening base material from moving in the direction of the roof slope during and after construction. For this reason, the ease of construction as well as the stability of the mounting is ensured. Unlike the prior art, it is not necessary to use a flat resin heat insulating plate in order to make the standing folded plate roof surface flat, so that the ease of construction is also secured from this. Furthermore, since a large concentrated load is not applied to the first bar member from above, a material having a small diameter can be used as the first bar member, resulting in a reduction in material cost.

  In one aspect of the structure for fixing the greening base material to the folded plate roof according to the present invention, one or two or more second bar members are attached to the first bar member in the roof gradient direction. The greening base material has a third groove on the back side, and the greening base material stands in a state where the second bar member is inserted into the third groove. It is fixed to the surface.

  In this aspect, since the movement of the greening base material in the direction orthogonal to the roof gradient direction is also prevented by the second bar member, the mounting posture of the greening base material is further stabilized. The second rod member may be attached to the first rod member at a position corresponding to the standing ridge, and in this case, the second concave groove is the third groove. Since the function as a concave groove can also be achieved, the third concave groove can be omitted.

  In the present invention, the bar member may be made of any material, but is preferably a metal bar, for example, a wire because it has a required strength in addition to ease of work and economy.

  According to the present invention, in the fixing structure for fixing the greening base material on the standing folded-plate roof, a greening base material fixing structure is provided that allows easy installation and a stable mounting posture of the greening base material. Is done.

  Hereinafter, the present invention will be described based on embodiments. In FIG. 1 and FIG. 4, R is a folded plate roof, and shows a cross section in the Y direction perpendicular to the roof gradient direction X. The standing folded plate roof R has left and right rising portions 1, 1, a horizontal top surface 2, 2 at the upper end thereof, and a standing rising portion 3, 3 rising vertically from the tip of the top surface 2. Using a long roof plate 5 provided, a fixture is used on a beam (not shown) while engaging the standing portions 3 and 3 of the adjacent roof plates 5 and 5 with each other. It is formed so as to be fixed. In the present invention, the portion formed by the horizontal top surfaces 2 and 2 at the upper ends of the left and right rising portions 1 and 1 is called the horizontal top surface 2 of the chevron, and the engagement between the standing top portions 3 and 3 The part stands and is called ridge 4.

  In the fixing structure of the greening base material according to the present invention, the greening base material 50 is placed on the folded plate roof R using the standing ridges 4 and the horizontal top surfaces 2 and 2 of the mountain-shaped portion of the folded plate roof R. Fix it. In fixing, first, one or two or more first bar members 10 such as wires are attached in a direction Y orthogonal to the roof gradient direction X using the top of the standing ridge 4. The first rod member 10 may be installed on the top of the ridge 4 by an appropriate method. In this embodiment, the fixing device 20 shown in FIG. 2 is used.

  Below, the fixing device 20 is demonstrated with the attachment method. The fixing device 20 has a pair of clamp pieces 21a and 21b that can hold the standing protrusion 4 from the left and right sides. As shown in FIG. 1, the fixing device 20 stands by the pair of clamp pieces 21a and 21b. The posture is such that the ridge 4 is clamped. Then, fixing bolts 24 are erected through openings 23, 23 formed in both horizontal top surfaces 22, 22, and the fixing bolts 24 are tightened with nuts 25. As a result, the pair of clamp pieces 21a and 21b are firmly fixed to the standing protrusion 4, and the fixing bolt 24 is erected vertically therefrom.

  Similarly, an appropriate number of fixing devices 20 are attached to the standing protrusion 4 of the folded plate roof R. In the example shown in the figure, the fixing devices 20 are attached to every other standing ridge 4 in multiple stages at a predetermined distance in the direction of the roof gradient direction X, and the fixing devices 20 at each stage are attached. Are arranged in a straight line in the Y direction orthogonal to the roof gradient direction X.

  The first rod member 10 described above is attached using a plurality of fixing devices 20 aligned in the Y direction that are fixed in this manner. In mounting, the first rod member 10 is temporarily locked by using the fixing bolts 24 standing on the plurality of fixing devices 20 aligned in the Y direction. From there, the locking tool 30 shown in FIG. 2 is attached. As shown in FIG. 2, the locking tool 30 has a box shape and includes four side walls 31 and a top surface 32. A first locking groove 33 is formed on two opposing side walls, and an opening 34 is formed on the top surface 32. 2 has a second locking groove 35 formed on two side walls orthogonal to the side wall on which the first locking groove 33 is formed, as will be described later. It is used when the second rod member 11 is fixed.

  After the first rod member 10 is temporarily locked as described above, the locking tool 30 is dropped while passing the fixing bolt 24 through the opening 34 formed on the top surface 32 thereof. As a result, the temporarily locked first bar member 10 is in a posture of entering the first locking groove 33 formed in the locking tool 30. By tightening the nut 26 in this state, the first rod member 10 stands and is in a state of being firmly fixed using the top of the protruding protrusion 4.

  A lattice-shaped frame member in which one or two or more second rod members 11 in the roof gradient direction are attached to the first rod member 10 can also be used. At that time, the second bar member 11 may be attached at any position in the Y direction of the first bar member 10, but the folded plate roof R stands at a position along the ridge 4. In the case where the second rod member 11 is inserted into the second locking groove 35 formed in the locking tool 30 at the time of fixing, the second rod is simultaneously mounted with the first rod member 10 when being attached. The member 11 is also fixed using the standing protrusion 4.

  Next, the greening base material 50 is stood and attached to the folded-plate roof. The greening base material 50 may be basically used in conventional rooftop greening. In this example, the greening base material 50 is an in-mold foamed resin molded product, and a large number of water storage cavities 51 are formed on the surface side. Yes. As shown in FIG. 3, on the back surface, when the stand is placed on a folded plate roof, the standing protrusion 4 and the fixing device 20 (and the second rod in the illustrated example) are fixed to the standing protrusion 4. The required number of first concave grooves 52 into which the member 11) can enter is formed. Further, the required number of second concave grooves 53 into which the first rod member 10 can enter is formed so as to be orthogonal to the first concave grooves 52. The depth of the first concave groove 52 and the second concave groove 53 is such that when the greening base material 50 is placed on the folded plate roof, the back surface thereof is the horizontal top surface of the mountain-shaped portion of the folded plate roof. The depth is such that it can be in contact with 2 and 2.

  Although the illustrated greening base material 50 is not essential, an appropriate number of slits 54 are provided as drainage grooves on the back surface portion in the vicinity of the first concave groove 52. The slit 54 has such a length that the back surface of the greening base material 50 reaches a position outside the top surfaces 2, 2 when the back surface is in contact with the horizontal top surfaces 2, 2 of the chevron of the folded plate roof. Has been. Further, although not essential, in the illustrated example, when the greening base material 50 is placed on the folded plate roof, the fixing bolts erected on the fixing device 20 fixed to the standing ridge 4. A through hole 55 (FIG. 1) through which the bolt can pass is formed at a position facing 24.

  In attaching the greening base material 50, the protruding protrusion 4 is set up in the first groove 52, the first rod member 10 is set up in the second groove 53, and the through hole 55 is set up in the above manner. The fixing bolts 24 are placed in the standing state on the folded roof. At that time, a part of the back surface of the greening base material 50 is in contact with the horizontal top surfaces 2 and 2 of the mountain-shaped portion of the folded plate roof R, and a stable posture is obtained. All fastening operations are completed by fastening the fastening nut 27 (FIG. 2) to the fastening bolt 24.

  In vegetation, an appropriate planting mat (not shown) or the like is placed on the greening base material 50, and a necessary watering or the like may be performed in a state where a scattering prevention mat (not shown) is attached thereon. Thereby, as shown in FIG. 4, the plant P grows on the greening base material 50. During vegetation, water may enter the area where the back surface of the greening base material 50 is in contact with the horizontal top surfaces 2 and 2 of the mountain-shaped portion of the folded-plate roof, but the water that has entered the top surface through the slit 54 described above. Therefore, it is possible to avoid corrosion on the top surfaces 2 and 2 of the chevron.

  In the structure for fixing the greening base material 50 to the folded plate roof according to the present invention, the first rod member 10 and the second rod member 11 when arranged are formed on the back surface. 2 and the third groove (as described above, the first groove 52 also serves as the first groove 52 in the example shown in the figure). Movement is restricted. Therefore, if it is possible to restrict the greening base material 50 from moving in the lifting direction by means such as the above-described anti-scattering mat, the first fixing tool 30 is used to fix the greening base material 50 with a short length. Only the rod member 10 is fixed, and the fixing of the greening base material 50 by the fastening nut 27 can be omitted, or the number of fixing portions can be reduced. In that case, since the through-hole 55 can be omitted or the number thereof can be reduced, the entire configuration can be simplified.

  Moreover, since the load from above applied to the greening base material 50 is received as a surface load in a wide area where the back surface of the greening base material 50 is in surface contact with the horizontal top surfaces 2 and 2 of the mountain-shaped portion of the folded plate roof, The stability of the greening base material 50 with respect to the load from is also obtained. In other words, since the concentrated load from above does not act on the first bar member 10 and the second bar member 11, even a thin wire or the like can have the required strength, Moreover, the pitch of the 1st rod member 10 and the 2nd rod member 11 can also be taken widely. This also leads to a reduction in material costs.
