DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a partition structure for a rooftop greening facility on which a waterproof sheet is laid and a method of repairing the partition structure.

[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) Brick or concrete blocks are placed on top of the partition structure (24), and mortar is used as a partition structure (24), or, as shown in Fig. 5 (b), a GRC block is placed on a tarpaulin (33) with a connector (37). The assembled partition structure (34) is adopted.

In the above-mentioned conventional greening equipment, since the waterproof sheets (23) and (33) are laid on the flat roof, the planting area (r) is provided.
Although rainwater does not leak to the skeleton side as well as irrigation in the above, leakage from the gap (e) between the partition and the waterproof sheet or from the gap (e ') between the partitions to the non-planting area (r'). is there. In the non-planting area (r '), a waterproof sheet (23)
However, (33) is liable to be deteriorated by ultraviolet rays or thermal deterioration due to sunlight due to its material, and cracks may be generated 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, in the planting area (r), it is not necessary to repair the waterproof sheet for a long period of time, whereas in the non-planting area (r '), it is necessary to repair the waterproof sheets (23, 33) due to deterioration. Will increase.

[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. .
