DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a partition structure in a green roofing facility on which a waterproof sheet is laid.

[0002]

2. Description of the Related Art In recent years, a roof of a building or a veranda of a general residential house has been used to lay a waterproofing sheet made of, for example, a vinyl chloride resin, to form a land roof structure. Greening has become popular by installing greening equipment for cultivating plants.

Conventionally, in this type of greening equipment on a land roof having a waterproof sheet laid thereon, as a partition structure between a planting area and a non-planting area, for example, as shown in FIG.
3) A partition structure (24) in which bricks and concrete blocks are arranged on a mortar, or as shown in Fig. 6 (b), a block made of GRC is placed on a tarpaulin (33) with a connector (37). The assembled partition structure (34) is adopted.

[0004] In this type of greening equipment, the non-planting area (r ')
Of the waterproof sheets (23) and (33) are liable to be deteriorated by ultraviolet rays or thermal deterioration due to sunlight due to their materials, and cracks may occur over time due to water leakage. Such a tendency is more remarkable in the non-planting area (r ′) exposed to the sunshine than in the planting area (r) covered by the soil (s). Therefore, the planting area (r)
Does not require the waterproof sheet to be repaired for a long time, whereas in the non-planting area (r '), the need for repair of the waterproof sheets (23) and (33) due to deterioration increases.

[0005] However, in the conventional partition structure (24) made of bricks or concrete blocks, the installation work is easy, but the weight is large, so that an unnecessary load is applied to the frame and the frame is damaged. In repairing the waterproof sheet (23), the soil (s) inside the partition is once removed, and then the bricks and concrete blocks hardened by mortar are broken down, and the waterproof sheet (23) in the non-planting area (r ') is destroyed. ) Needs to be finished to the partition structure again after the repair, which is not only complicated, but also may cause unnecessary damage to the waterproofing sheet (23) in the non-planting area (r ') during the repair work.

Further, in the above-mentioned conventional partition structure (34) made of a GRC block, since it is relatively light in itself, a large load is not applied and it does not damage the frame, but when the waterproof sheet (33) is modified, After removing the soil inside the partition, it is necessary to disassemble the connector (37), disassemble it, reassemble the waterproofing sheet (33) in the non-planting area (r ') and reassemble it into the partition structure (34). Yes, similar to the partition structure (24) made of bricks and concrete blocks, it is not only complicated, but also the waterproof sheet (33) in the non-planting area (r ′) may be unnecessarily damaged during the repair work. .

The present inventor has proposed a waterproof sheet (4) as shown in FIG.
3) On the upper surface, an extended partition member (44) and a corner partition member (45) made of a PVC steel plate having a hat shape having an edge portion (e) are connected and arranged, and a waterproof sheet (43) and A rooftop greening partition structure formed by joining and integrating a watertight sheet (43s) with the edge (e) has been previously proposed (Japanese Patent Application No. 8-153763).

[0008] However, the partition structure proposed above is light in itself and has the advantage of not imposing a weight burden on the skeleton, as well as the waterproof sheet, but has the trouble of manufacturing members and assembling on site. There is a drawback of hanging.

[0009]
