Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a horizontal roof suitable for snowy regions and capable of snow melting and cooling in summer.

[Prior art and problems to be solved by the invention] In general, in snowy regions, roofs are steeply sloped to allow snow to fall naturally, but on the other hand, snow stops are installed to prevent danger, and snowfall is mainly done manually. The effort involved is excessive. Efforts have been made to solve these problems, but they are often economically difficult.

In view of the above circumstances, and based on many years of design experience, the applicant has discovered that horizontal roofs are suitable for roofs in areas with heavy snowfall. In other words, when we look at the phenomenon of snowfall along with the wind, the snow constantly tends to flatten, making it difficult for snow to accumulate on buildings with horizontal roofs. Then, by keeping the roof level and using the rain gutters as internal gutters, the remaining heat from the heater will melt the snow.

On the other hand, with pitched roofs, once the water melts, it forms limescale on the eaves and does not flow down to the ground.

Also, in the summer, if water is allowed to accumulate on the horizontal roof, a cooling effect can be expected.

This invention was developed by comprehensively considering the above circumstances.

[Means for solving problems]

This invention forms a prevention layer on the top surface of a horizontal roof to make almost the entire surface into a water storage tank, and the water storage tank is equipped with an overflow pipe and a drainage pipe with an opening/closing mechanism. The melted water is drained through open drainage pipes, and during the summer, the water is retained in a water storage tank constructed on the roof.

This is a horizontal roof that keeps the drainage pipes closed.

〔Example〕

The details will be explained below with reference to illustrated embodiments. The roof is a horizontal roof, that is, a flat roof, and a rising part 2 or a parapet is formed around it, and this roof 1
A waterproof layer 3 made of iron plates or the like is provided on the upper surface of the tank, and a relatively shallow water tank 4 is formed on the entire or substantially entire roof surface.

This water storage tank 4 is provided with a drain pipe 5 and an overflow pipe 6, each serving as a rain gutter, and it is desirable to provide each of them inside the outer wall 7. A valve 8 is provided at the bottom of the drain pipe 5 as an opening/closing mechanism. Drain pipe 5. The overflow pipes 6 are each covered with a heat insulating material, and their lower ends are gathered together to form a rain gutter 9, which is opened into a drainage channel 10 in the form of a trap.

In addition, it is desirable to install a snow gauge 11 on the roof and a heater 12 under the eaves of the eaves.

[Function and effect of the invention]

This invention has the above-mentioned configuration, and in winter, snow accumulates on the horizontal roof, but due to the influence of indoor heating, the snow on the roof melts from the bottom. Then, when the valve 7 is opened, water is drained through the drain pipe 5. In the summer, when the valve 7 is closed, water accumulates on the horizontal roof, forming a water tank, which cools the roof surface and provides an air-conditioning effect for the room below.

Excess rainwater on the roof is also drained away through overflow pipes.

Furthermore, according to the structure of the present invention, even in the case of heavy snowfall, the snow scatters, and since there is a layer of water between the snow and the roof surface, the roof surface and snow separate in the event of an earthquake, reducing the horizontal force that the snow load exerts on the building. significantly reduced.

Note that, as shown in the embodiment, by arranging the lower end of the rain gutter in a trap shape, freezing inside the drain pipe or the like can be prevented.
