Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention provides a roof structure that can be used for snowing without snowing labor and electricity costs.

[0002]

[Prior art]

 In heavy snowfall areas, snow removal work must be carried out to avoid damage to houses due to snow. Conventional snow removal methods mainly use snow removal using a hand-pushed snow removal tool, and some methods include melting and flowing snow by electric heat.

[0003]

[Problems to be solved by the device]

 The above-mentioned snow removal work that relies on human power is not only a heavy labor, but there is a risk of falling from the roof and injuring yourself.When using electric heat, a large amount of electricity is consumed, , Has a cost problem.

[0004]

[Means for solving problems]

 The present invention has been made for the purpose of solving the problems associated with the conventional snow removal work described above, and is configured as follows. A lower roof made of a material that does not allow gas to permeate, with a gas sealing member attached to the periphery, and a material with gas permeability that has a chemical heat storage material sealing member attached to the periphery of the lower roof. A partition plate disposed above and supported on the lower roof via a stopper that slides in the vertical direction, a gas pipe with a valve connected to a vacant chamber formed between the lower roof and the partition plate, and thermal conductivity. It is made of a material that does not allow gas to pass through, has an upper roof that is placed above the partition plate, and has a chemical heat storage material inside the space formed between the partition plate and the upper roof. It is provided with a structure in which gas is filled in an empty space formed between the lower roof and the partition plate described above.

As the chemical heat storage material filled in the space formed between the partition plate and the upper roof, a substance that undergoes a solid-gas reversible reaction is used, and when the gas is an NH ₃ gas system, Are, for example, CaCl ₂ , BaCl ₂ , NH ₄ Cl and (NH ₄ ) ₂ SO _4, etc., and are appropriately selected depending on the amount of snow and the angle of the roof. Since a substance that undergoes a solid-gas reversible reaction is used as the chemical heat storage material, the partition plate must have excellent gas permeability, and the material for the lower roof is used that does not have gas permeability.

A stopper provided below the partition plate and supported on the lower roof is supported elastically by an appropriate spring force or the like, and slides downward when the amount of snow on the upper roof exceeds a specific amount. , It is configured to return upward as the snow is melted and slides down.

[0007]

[Action]

 In the roof according to the present invention having the above-mentioned structure, the partition plate supporting the filled chemical heat storage material is pushed down by the load due to the increase in the amount of snow, and at the same time, it is enclosed between the partition plate and the lower roof. The gas is pressurized. Then, the equilibrium state between the chemical heat storage material and the gas collapses, and the chemical heat storage material absorbs the gas to cause an exothermic reaction, raises the temperature and transmits it to the upper roof, and melts the snow on the upper roof to slide it off. When the snow on the upper roof slides down, the equilibrium between the chemical heat storage material and the gas collapses again, and the chemical heat storage material emits gas and returns to its original state.

【Example】

 An example of the structure of the roof according to the present invention is shown in FIG. The lower roof 4, which is made of a material that does not allow gas to permeate and has a gas sealing member 3 provided around it, is supported by the ceiling plate 2 and the wall 1 to which the supporting plate 5 is attached, and has a material having gas permeability. A partition plate 8 which is manufactured and provided with a member 7 for sealing the chemical heat storage material on the periphery thereof, and which is provided with a stopper 6 that can slide in the vertical direction as described later based on FIG. 2, is arranged above the lower roof 4. It is supported by the lower roof 4, and the gas pipe 10 with a valve is connected to the vacant space formed between the lower roof 4 and the partition plate 8. It is made of a material that has excellent thermal conductivity and is impermeable to gas. The upper roof 12 is arranged above the partition plate 8 to form a space between the upper roof 12 and the partition plate 8, and the chemical heat storage material 9 is filled in the space between the partition plate 8 and the upper roof 12. Gas is filled in the empty space formed between the lower roof 4 and the partition plate 8. There. The member denoted by reference numeral 11 is a roof movable sealing member for coping with relative movement in the vertical direction of both roofs facing each other in the figure.

The structure of the stopper 6 disposed between the lower roof 4 and the partition plate 8 is shown in FIG. A support rod 13 connected to the lower surface of the partition plate 8, a pair of spring receivers 14 and 14 attached to the lower roof 4, springs 15 and 15 supported by each spring receiver 14, and a spring guide 16 supporting each spring 15. 16 and the ends of the springs 15 are engaged with the concave grooves provided on both sides of the support rod 13 and are composed of locking pieces 17, 17, which are disengaged when the amount of snowfall exceeds a specific amount and the partition plate 8 is pushed down, the snow is melted, and it extends upward and pushes up the partition plate 8.

Six sets of stoppers 6 made of stainless steel were used to support a 4 m ² upper roof 12 made of aluminum and a partition plate 8 made of a porous material. The spring constant of each spring 15 is 5. 8 kg of (NH ₄ ) ₂ SO ₄ was filled on the partition plate 8 as the chemical heat storage material 9. After degassing the inside with a vacuum pump through the valved gas pipe 10, 2 m ³ of NH ₃ gas was supplied at a pressure of 8 atm to close the valve.

When the above-described roof was inclined 20 degrees with respect to the ground to artificially make snow, when about 30 cm of snow was accumulated, the snow naturally slipped down the roof. When he continued to make it snow more, when the amount of snow reached 30-50 cm, the snow naturally slipped off the roof. After the snowfall was over, there was no change in the roof.

[0012]

[Effect of device]

 The roof according to the present invention is made of the gas permeable material as described above, and is made of the partition plate and the gas impermeable material supported on the lower roof by the gas impermeable material through the stopper that slides in the vertical direction. The chemical heat storage material is filled inside the space formed between the upper roof and the upper roof, and the space between the lower roof and the partition plate is filled with gas. The partition plate that supports the load is pushed down by the load that accompanies the increase in the amount of snow, and at the same time, the gas enclosed between the partition plate and the lower roof is pressurized to equilibrium state between the chemical heat storage material and the gas. When the snow falls on the roof, the chemical heat storage material absorbs gas and causes an exothermic reaction, raising the temperature and transmitting it to the upper roof, melting the snow on the upper roof and causing it to slide off. Equilibrium of wood and gas is scrap Since the chemical heat storage material is returned to the original state by generating a gas, it is not necessary to the that by the human-powered snow removal, power consumption also is not required.
