Description

TECHNICAL FIELD The present invention relates to a roof snow erasing device that melts snow on a roof by letting out warm air in the building onto the roof.

[Problems to be Solved by Conventional Techniques and Inventions] In Niigata Prefecture, which is a heavy snowfall area, various roof snow removing devices have been developed.

The main ones are as follows.

A method of removing snow by installing a watering device such as a watering nozzle or watering pipe on the roof.

A method of melting snow on the roof by directly melting it with a heater, warm air, exhaust heat, etc.

A method of heating the attic with a heater, warm air, exhaust heat, etc. to indirectly melt the snow on the roof and eliminate the snow. However, the method has the drawback that the roof is easily damaged and is not durable, or water leaks when the roof freezes.The method does not directly hit the snow, so the snow removal efficiency is poor, and in the case of heavy snow Is not so effective.

The present inventor projects a large number of exhaust heat pipes with a cover on the roof surface, and from this exhaust heat pipe, the exhaust heat in the building is directly drawn into the snow, and the snow is melted from the inside to extinguish the snow. We have developed a snow-melting method and have already filed several applications such as JP-A-62-242044.

The present invention is an improvement of the exhaust heat pipe in these systems.

[Means for Solving the Problems]

 The detailed description will be made with reference to the accompanying drawings.

Exhaust heat pipe 4 for discharging warm air in the building b is provided on the roof a, and a cover 5 is provided above the exhaust heat pipe 4 to prevent snow and rain from entering the exhaust heat pipe 4. In the apparatus, the exhaust heat pipe 4 is pressed onto the roof plate 1 by press drawing.
And a rising short inner cylinder 4c continuously formed with the rising short inner cylinder 4c and an outer cylinder which is fitted on the outside of the rising short inner cylinder 4c and is taller than the rising short inner cylinder 4c.
The present invention relates to a roof snow eliminator characterized by being configured with 4d.

[Action]

The warm air in the building b is led out onto the roof a from the heat exhaust tube 4. The warm air directly contacts the snow on the roof a and melts the snow from the inside. The snowmelt water will flow down on the roof a.

Since the rising short inner cylinder 4c of the present invention is formed in a continuous state with the roof plate 1 by drawing, the snowmelt water does not drip into the building b.

By the way, the short inner cylinder 4c is formed by directly press-drawing the roof plate 1, but it cannot be installed so high because it is drawn within the bore diameter. When the exhaust heat pipe 4 is low, the intake of warm air becomes poor, and snow and rain easily enter, but in the present invention, since the outer cylinder 4d is fitted, the intake of warm air is good, and snow and rain Intrusion is surely prevented.

〔Example〕

The case where the present invention is applied to a roof tile roof is illustrated. A support leg 8 is erected on the roof tile 2 through a packing 6, and a cover 5 is installed on the support leg 8. It is fastened to the avalanche angle 16 attached to the rod 2 and joined in a direction crossing over the roof a. In this case, the exhaust heat pipes 4 are formed in rows provided at a predetermined interval in the direction crossing the roof a, and the exhaust heat pipes 4 are formed in multiple rows from the eaves side to the ridge side.

In the figure, reference numerals 7c and 7d are rising short inner cylinders 4c, and warping collars of the outer cylinder 4d, 9 is a mesh cover, 10 is a dew condensation cover that prevents dew condensation from dripping into the heat exhausting cylinder 4, and 11 is snow. A snow plate that is hanged down in series on the front side of the dew condensation cover 10 so as not to be inserted, 12 is a fastening member, 13 is a fastening bolt, 14 is a reinforcing strip, and 15 is a thick reinforcing bar.

〔The invention's effect〕

Since the present invention is configured as described above, it is an excellent roof snow erasing device that does not cause dripping of snow-melting water into a building, absorbs warm air favorably, and prevents snow and rain from entering the building.
