2. Description of the Related Art Conventionally, in a steel frame building or a unit building, a flat roof with a horizontal or extremely small slope may be provided. This flat roof was usually composed of a folded plate roof made of a corrugated iron plate. However, in recent years, flat roofs using ALC panels excellent in fireproofing, heat insulation and sound insulation have been constructed in order to improve the living performance of buildings. It is necessary to attach a waterproof sheet to the roof of the ALC panel for waterproofing. Therefore, as shown in FIG. 11, the waterproof sheet 102 is provided on the upper surface of the ALC panel 101 supported by the frame 100 made of channel material or the like. While sticking and waterproofing, the eaves of the flat roof is provided with a parapet 103 such as an ALC panel,
The edge of the waterproof sheet 102 was erected and stuck along the inner wall side of the parapet 103. That is, by fixing the end portion of the waterproof sheet 102 at a position higher than the upper surface of the ALC panel 101, rainwater that has fallen on the flat roof is prevented from entering from the edge of the waterproof sheet 102 and the waterproof performance is improved. It was

By the way, since the parapet needs to have a certain height, the parapet may not be able to clear the diagonal restrictions in the building regulations such as road diagonal lines and north diagonal lines. Especially, in case of unit type flat roof consisting of multiple roof units to shorten the on-site construction period, it is difficult to adjust the height dimension of the parapet according to various diagonal restrictions, and it is applied to buildings with diagonal restrictions. It was difficult to do. Therefore, in the unit type flat roof, there has been a demand for an eaves tip structure capable of fixing the edge of the waterproof sheet and providing a reliable waterproofing treatment without providing a parapet at the eaves tip portion.

An object of the present invention is to provide a unit-type flat roof eaves structure capable of performing a reliable waterproof treatment without providing a parapet.

[0005]

It is characterized by comprising a member and a waterproof sheet attached from the upper surface of the roof unit to the horizontal portion of the eaves member and the waterproof sheet fixing portion.

[0006]

In the present invention as described above, the parapet is not provided on the eaves of the unit type flat roof, and the horizontal portion protruding from the side surface of the roof unit and the waterproof provided substantially vertically downward or diagonally downward from the horizontal portion are provided. The eaves member with the seat fixing part was attached, and the waterproof sheet was attached from the upper surface of the roof unit to the waterproof sheet fixing part through the horizontal part of the eaves member, so rainwater that fell on the unit type flat roof protruded from the side surface of the roof unit. It flows through the horizontal portion and the waterproof sheet fixing portion, and is drained by eaves gutters and the like that are appropriately provided under the waterproof sheet fixing portion and the like.

Therefore, rainwater does not enter the roof unit from the edge of the waterproof sheet, and the edge of the waterproof sheet is surely waterproofed without providing a parapet at the eaves. Also, since the roof unit is formed flat,
It can be easily stacked and transported, and transportation efficiency is also improved. Furthermore, rainwater that falls on the roof unit is drained through the eaves member at the eaves gutter provided around the flat roof, so there is no need to install a drainage facility inside the building as in the conventional system, and the storage is easy. In addition, there is no risk of water leaking indoors, and waterproofing will be simple.
