  Embodiments of the present invention will be described below with reference to the drawings. In the drawings, the parts indicated by the same reference numerals as in the conventional example indicate the same or corresponding parts.

FIG. 1 shows a building B provided with one embodiment of the roof structure of the present invention.
The building B of this embodiment is a reinforced concrete building in which a building body B1 and a roof B2 formed thereon are integrally formed.

As shown in FIGS. 1 and 2, the roof B <b> 2 is configured to be inclined so that an upper surface portion (a planting portion described later) can be seen when viewed from a position away from the building B.
Moreover, the planting part S which put the soil 1 is provided on the said roof B2, It is comprised so that the plant growing in this planting part S can be appreciated in the position away from the building B.

Further, as shown in FIGS. 2, 3 and 5, a vinyl chloride waterproof sheet 4 is bonded and fixed to the upper surface of the roof B2, and water is further retained in the planting part S thereon. A possible water retaining mat 2 is provided so as to overlap the waterproof layer.
In addition, above the water retaining mat 2, a soil support net 5 is supported by a plurality of support members 3 fixed in a protruding state on the top surface of the waterproof sheet 4. It becomes possible to carry the soil 1 and make it difficult to slip off.

Incidentally, the waterproof sheet 4 is attached and fixed by adhesion to a waterproof sheet fixing bracket 6 fixed to the roof B2. Adjacent sheets are reliably integrated by welding.
With regard to the material of the waterproof sheet 4, the use of vinyl chloride makes it possible to ensure an appropriate strength, strengthen the soil 1 displacement prevention effect, and prevent the roots of the planting part S from penetrating. It becomes possible to plan.
As shown in FIG. 4, for example, as shown in FIG. 4, the waterproof sheet fixing bracket 6 is a hot melt made of a thermoplastic synthetic resin that melts polyester resin or the like on the upper surface of a stainless steel disc having a diameter of about 50 mm and exhibits adhesion. The washer body 6A is covered with an adhesive layer H. The washer body 6A is disposed on the roof B2 at predetermined positions in the vertical and horizontal directions and is screwed.
The waterproof sheet 4 is fixed to the roof B2 by setting an electromagnetic induction heating device above the waterproof sheet 4 covered on the washer body 6A, and heating the washer body 6A by electromagnetic induction heating. The washer layer 6A and the waterproof sheet 4 can be bonded by dissolving the adhesive layer H (see FIG. 5).

The water retaining mat 2 is formed by integrating a mat main body (corresponding to a water retaining main body) 2A formed by interlacing fibers made of water-absorbing polymer into a mat shape, and an adhesive portion 2B to the waterproof sheet 4.
The fiber material constituting the mat body 2A can be constituted by a water-absorbing polymer such as starch, cellulose, or synthetic polymer, for example.
The starch system and the cellulose system each have a graft polymerization system and a carboxymethylation system, and the synthetic polymer system includes a polyacrylate system, a polyvinyl alcohol system, a polyacrylamide system, and a polyoxyethylene system. There are various types.
The adhesive portion 2B is composed of an adhesive sheet containing vinyl chloride as a main component. The water retaining mat 2 is adhered to the waterproof sheet 4 by applying a solvent and bringing it into contact with the waterproof sheet 4 and pressing it. be able to. And since both the said adhesion part 2B and the waterproof sheet 4 are vinyl chloride as a main component, when welding with the said solvent, both are familiar and can adhere | attach strongly.
However, the attachment portion of the support member 3 to the waterproof sheet 4 is disposed so as to cover the base portion 3 a of the support member 3. And the main-body part 3b of the supporting member 3 penetrates the water retention mat 2, and protrudes upwards.
By adhering the water retaining mat 2 along the waterproof sheet 4, the water that has entered the planting part S flows along the roof slope on the waterproof sheet 4 toward the lower side of the slope. The water retaining mat 2 is sufficiently retained. Therefore, when the soil 1 is dried, the water retained in the water retaining mat 2 is supplied to the plants and plants of the planting part S, and it becomes possible to alleviate the drought.

The support member 3 is made of vinyl chloride, and includes a base portion 3a and a main body portion 3b as shown in FIG.
The base portion 3a is constituted by a disc, and the main body portion 3b is constituted by a resin bolt provided integrally and upright at the central portion of the disc.
And the supporting member 3 is installed in the state which the main-body part 3b protrudes on a roof surface by carrying out the surface bonding of the disk-shaped base part 3a on the waterproof sheet 4. FIG. The main body portion 3b is provided with a pair of locking ring members 3c that can be freely locked to the external threaded portion of the outer periphery, and the support net 5 is interposed between the locking ring members 3c. It can be pinched and fixed. Therefore, in a state where one locking ring member 3c is locked to the main body portion 3b, the through hole of the net 5 (the soil 1 is configured to pass through in the thickness direction of the planting portion S) 5b. The net 5 is placed on the one locking ring member 3c through the main body portion 3b, and the net 5 is fixed to both locking ring members while the other locking ring member 3c is locked to the main body portion 3b. The net 5 can be supported and fixed by the support member 3 by being sandwiched by 3c.
Further, the locking ring member 3c will be described. Like the base portion 3a and the main body portion 3b, the locking ring member 3c is made of a synthetic resin. As shown in FIG. The locking piece 7a is integrally provided.
Each locking piece 7a is formed in a posture inclined to one side with respect to the ring axis, and the locking ring member 3c is used as a bolt axis from one end side of the main body portion 3b made of the resin bolt. When the fitting operation is performed along each of the locking pieces 7a, the locking pieces 7a are easily bent and can be easily fitted. 7a is stretched so that it is difficult to remove.
Incidentally, the locking action of the locking ring member 3c to the main body portion 3b is effective when the tip end portion of the locking piece 7a is engaged with the outer peripheral male screw portion of the main body portion 3b. Further, in order to remove the locking ring member 3c from the main body portion 3b, the same operation as removing the nut from the bolt (by rotating the locking ring member 3c around the bolt axis along the male screw portion) is performed. To be implemented.
Moreover, since the latching position of the latching ring member 3c with respect to the main-body part 3b can be changed, it becomes possible to also change the support height of the net | network 5, for example, the soil layer of the planting part S It is possible to easily adjust the support height of the net 5 to a preferable value according to the set thickness dimension and the type of plant to be grown. The main body portion 3b and the locking ring member 3c are referred to as height changing means 8.

The net 5 will be described. As shown in FIG. 3, the net 5 is a resin net integrally formed so that a large number of juxtaposed vertical line portions and a large number of juxtaposed horizontal line portions intersect. A space surrounded by the adjacent vertical line portion and the adjacent horizontal line portion is secured as the through hole 5b. This through-hole 5b is set to a size that allows the soil 1 of the planting part S to penetrate, and the net 5 is supported on the roof B2 by the support members 3 as described above, from above. When the soil 1 is covered, it is considered that the soil 1 also passes through the through hole 5b to the lower side of the net 5.
Therefore, after the net 5 is installed, even if the planting part S is filled with the soil 1, the soil spreads over the water retention mat 2, and the net 1 is buried in the soil by depositing the soil 1 to a predetermined thickness. Is possible. As a result, this net 5 can carry the soil 1 of the planting part S and prevent the soil from falling along the roof slope.

  In addition, regarding the prevention of the slipping of the planting part S, in addition to the use of the supporting action of the net 5 and the soil 1 described above, the receiving part 11 made of the net 11A is formed on the inclined lower part 10 of the roof B2. It is also made use of the expected soil acceptance.

Specifically, as shown in FIG. 2, the lower edge portion of the net body 11 </ b> A having a finer mesh than the net 5 is installed on the lower roof slope side of the support member 3, and the lower edge portion is the roof B <b> 2. It is fixed to.
And 11 A of said net | networks are arrange | positioned in the state which wraps the inclination lower edge part of the planting part S, and the upper edge part is fixed with the hook-shaped stopper F along the surface of the planting part S. Has been.
As with the net 5, the net 11A is a resin net that is integrally molded so that a large number of juxtaposed vertical lines 11a and a large number of juxtaposed horizontal lines 11b intersect. (See FIG. 3), a space surrounded by the adjacent vertical line portion 11a and the adjacent horizontal line portion 11b is secured as the through hole (corresponding to the see-through portion 13) 13a. The through hole 11 c is formed smaller than the through hole 5 b of the net 5. Therefore, it is easy to receive the soil 1 of the planting part S flowing down from the inclined lower edge part covered with the net body 11A. However, as the plant of the planting part S grows, it is acceptable to extend to the surface side through the through hole 11c.
Furthermore, since the planting part S can be seen through the through hole 13a, it is possible to appreciate the lower edge of the planting part even when approaching the roof, and to improve the aesthetics of the planting roof. It becomes possible.

Next, a method for forming the planting on the roof of the building will be described with an example.
