Abstract

PURPOSE:To effectively vanish snow with a snow cover on a bent board roof made to be melted by driblets by alignedly providing a long size bent board at given intervals, standingly providing a chimney on the upper part of a long size bent board covering the interval, and covering the upper surface of the chimney with a snowbreak cover. CONSTITUTION:A bent board roof a is formed while alignedly provided by interposing a given interval 1 between adjoining song size bent board 1 and 1'. Then the interval 1 is sealed by covering between the top parts 2 and 2' of the adjoining bent board 1 and 1' with long bent board 3 and 3, and flat parts b and b having many threads are alignedly provided. After that, a chimney 4 is standingly provided leaving an appropriate interval in the longitudinal direction of the bent board 3 and 3 in the parts of (b) and (b). Moreover a snowbreak cover 5 is mounted on the direct upper part of the chimney 4, so that the infiltration of rain and snow into the chimney 4 is prevented. And an indoor warm air is led to be discharged from the chimney 4, and the snow cover on the roof a is melted by driblets to vanish snow.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a folded roof snow removal device that melts accumulated snow on a folded roof by directing warm indoor air onto the roof.

[Problems to be solved by conventional technology and invention]

In Niigata Prefecture, an area with heavy snowfall, various roof lightning extinguishing devices have been developed.

The main ones are as follows.

■ A method of dissolving snow by installing water spray devices such as water nozzles and water pipes on the roof.

■ A method of melting snow on the roof directly using heaters, warm air, waste heat, etc.

■ Attic heater A method of heating the attic with hot air, waste heat, etc. to indirectly melt snow on the roof.

However, the ■■■ method has the drawback that the roof is easily damaged and is not durable, and water leaks when the roof freezes 4 degrees. Unfortunately, it was less effective in cases of heavy snow.

The inventor of the present invention installed a large number of heat exhaust pipes with snow protection covers protruding from the roof surface, and conducted the exhaust heat inside the building directly into the snow from these heat exhaust pipes, melting the snow from the inside and extinguishing lightning. The company has developed a lightning extinguishing method and has already filed several patent applications including Japanese Patent Application No. 84724/1984.

The present invention utilizes these methods for a folded roof.

[Means to solve the problem]

The details are as follows with reference to the accompanying drawings.

When forming the folded plate roof a by arranging the long folded plates 1 side by side, the long folded plates 1 are arranged side by side with a predetermined gap ρ interposed between adjacent long folded plates 1.1°, Long plate 3 between adjacent nuchal parts 2 and 2°
A plurality of flat parts are arranged in parallel by covering the gap e, and heat exhaust pipes 4 are erected on the flat parts at appropriate intervals in the length direction of the elongated plate 3. There is a heat exhaust pipe 4 directly above the heat exhaust pipe 4.
This relates to a folding roof snow removal device characterized in that a snow cover 5 for preventing snow and rain from entering the roof is constructed over the folding roof a.

Further, long folding plates 1 are arranged side by side to form a folding plate roof a, a heat exhaust hole 4° is provided in this folding plate roof a in a water sprinkling state, and a heat exhaust pipe 4 is erected in the heat exhaust hole 4°. 7. A folded roof characterized in that a snow cover 4 for preventing snow and rain from entering the heat exhaust pipe 4 is installed on the folded roof a at the straight-h portion of the heat exhaust pipe 4. This relates to snow removal equipment.

[Effect]

In the first invention, warm air inside a building with a folded roof a is led to the folded roof a J: from a heat exhaust pipe 4 provided on the flat part of the folded roof a.

This heat exhaust cylinder 4 is constructed by arranging the folded plates 1 side by side with the tops of adjacent edges overlapping as in the usual method, but by arranging them with a predetermined gap a between them, and covering this gap σ with the long plate 3. Closed to form a multi-striped flat part on the folded roof a 1-1 Since the heat exhaust pipe 4 is erected on this flat part, the indoor warm air is led out onto the folded roof a on average, and the surface Since the snow is guided and discharged to the surrounding area by the snow protection cover 5 installed above, the snow on the folded roof a is not melted from the inside.

At this time, the warm air drawn out from the heat exhaust pipe 4 tends to head towards the front side -L, so the snow melting cavity tries to expand greatly towards the front side, but due to the slope of the roof, it is pushed towards the 5 rows of snow covers. It will not grow very large and will be melted directly by warm air.

Since this melted water is originally from the folded roof a, it will be drained away.

Moreover, the snow cover 5 serves to prevent snow and rain from entering the heat exhaust pipe 4.

In addition, in the second invention, the long folded plate 1 is directly joined at appropriate intervals, for example, in an overlapping state at the ends, not at the top 2 but at the intermediate top 2'' or at the slope 12 (it is better to dispose of water on the slope). A heat exhaust hole 4° is provided in the heat exhaust hole 4'', and a heat exhaust tube 4 is attached to the heat exhaust hole 4'' by an appropriate means, through which indoor warm air is led out in the same manner as described above.

The following is the same as the first invention.

〔Example〕

The drawing shows a case in which a long plate 3 having sleeve pieces 7 bent on the left and right sides is attached via a backing material 6 such as a wood wool plate.

The snow cover 5 is installed on a thin box-shaped support leg 8 attached to the top 2'' of the folded roof a through a backing material 6, but in the illustrated embodiment, one piece is attached to two rows of left and right heat exhaust pipes 4. Although the figure shows a case in which the snow covers are constructed over a folded roof a and joined in a direction transverse to the top of the folded roof a, the spacing between the five rows of snow covers is designed in consideration of the snow conditions in the area.

In the figure, reference numeral 9 is a net cover, and 10 is a condensation cover that prevents condensation from dripping into the heat exhaust cylinder 4. The figure shows a case in which the snow protection plate 11 is connected and suspended on the side to prevent snow from entering. .

Since FIG. 4 shows the case where two heat exhaust cylinders 4 are installed facing each other on both side slopes 12 of the long folded plate 1, care must be taken to prevent water leakage.

Of course, it may be one piece, or it may be provided on the top 2, and should be designed with snow conditions in mind.

〔Effect of the invention〕

Since the present invention is configured as described above, when constructing a folded plate roof, the folded plates are arranged side by side with a gap between them, and the elongated plates provided with the heat exhaust tubes are covered, and the heat exhaust tubes are covered with long plates. By simply installing a snow cover on top of the folded roof, warm indoor air is drawn out onto the folded roof, which melts snow on the folded roof little by little and extinguishes lightning, making it an excellent building that does not require snow removal. The purpose of this invention is to provide a folding roof snow removal device that exhibits excellent practicality.
