Abstract

(57) [Abstract] [Purpose] To prevent the roof from decaying due to the dew condensation when forming the ground plate, and to suppress the temperature rise in the attic due to solar radiation. [Structure] A moisture absorbing / releasing material 2 that absorbs and releases moisture is integrally attached to the back surface of a rigid plate 1.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a field board to be installed on a rafter or a main house to put a roof material through a waterproof sheet in a general house or the like.

[0002]

[Prior art]

 Conventionally, a non-water-absorbing heat insulating material has been integrally attached to the back surface of a rigid plate so that the rise in the room temperature due to solar radiation is suppressed by the heat insulating effect of the heat insulating material.

[0003]

[Problems to be solved by the device]

 However, especially in winter, when the dew condensation occurs on the back surface of the plate due to a decrease in outside air temperature or a decrease in temperature of the plate due to nighttime radiation, the plate will rot. Furthermore, there is a risk that the dew condensation water will drip and the ceiling will be rotted by moisture, and there is room for improvement in terms of preventing decay and preventing condensation dripping. The purpose of the present invention is to prevent dew condensation and to surely prevent the decay of the ceiling due to the drip of dew condensation, and to use the means for that to sufficiently suppress the temperature rise in the attic due to solar radiation. There is a point to do.

[0004]

[Means for Solving the Problems]

 A characteristic feature of the present invention is that a moisture absorbing / releasing material that absorbs and releases moisture is integrally attached to the back surface of the rigid plate body to form the base plate.

[0005]

[Action]

 In other words, since a moisture absorbing / releasing material is attached to the back surface of the plate, if there is a decrease in outside air temperature, a decrease in temperature due to nighttime radiation, and a rise in relative temperature, moisture is absorbed and retained, and dew condensation can be prevented. Also, the absorbed moisture is released to the outdoors by exhaust ventilation during the daytime when the temperature rises. Therefore, even if the back surface of the plate body or dew condensation occurs due to a decrease in the outside air temperature, the dew condensation can be absorbed by the moisture absorbing / releasing material so that it does not drip on the ceiling, and the decay of the ceiling due to the dew condensation can be reliably prevented. . In addition, a humidifier is used to supply moisture to the moisture absorbing / releasing material, and at night, the attic is forcedly ventilated by a fan so that the moisture contained in the outside air is absorbed by the moisture absorbing / releasing material. When the fan is forcedly ventilated, the moisture absorbed by the moisture absorbing / releasing material is vaporized by forced air exchange during the day, and the attic can be cooled by latent heat of vaporization of the moisture. To further explain, since a large amount of heat is required to vaporize water, the cooling capacity of the undergarment due to latent heat of vaporization is extremely large, and even in the summer, the temperature rise in the attic due to solar radiation can be sufficiently suppressed, Indoor temperature rise can be suppressed sufficiently.

[0006]

[Effect of device]

 As a result, it became possible to prevent dew condensation, and thus to prevent the decay of the ceiling due to the dripping of dew condensation, and to provide an even more excellent floorboard that is effective for cooling the attic.

【Example】

 As shown in FIG. 1, a moisture absorbing / releasing material 2 that absorbs and releases water is integrally attached to the back surface of a rigid plate body 1 such as plywood or particle board, and is used as a roofing material for a building such as a house. Formed the field board used to mount the. The moisture absorbing / releasing material 2 is, for example, a soft wood fiber board, foamed porous material, rock wool or glass wool containing a well-known super absorbent resin, a wood piece board, and a wood assembly with the front and back faces facing each other. Such as a plate. Next, a usage pattern of the above-mentioned base plate will be described. As shown in FIG. 2, the floor board is placed on the rafter 4 with the moisture absorbing / releasing material 2 facing the attic 3, and the roofing material 6 is placed on the rigid board 1 via the waterproof sheet 5, Even if dew condensation occurs on the back surface of the plate 1 due to a decrease in the outside air temperature, the dew condensation is absorbed by the moisture absorbing / releasing material 2 to prevent the roof 7 from decaying due to the dew condensation. Then, an intake port 8 is formed for the attic 3 and an exhaust pipe 9 is connected, and a fan 10 driven by a commercial power source or a solar cell is provided at the exhaust pipe 9 to exhaust the air inside the attic 3. While exhausting from the cylinder 9, the outside air is introduced into the attic 3 through the intake port 8 so that the attic 3 can be forcibly cooled, and the heat insulating material 11 is lined on the back surface of the ceiling 7. That is, the attic 3 is forcedly ventilated by the fan 10 at night so that the moisture contained in the outside air is absorbed by the moisture absorptive and desorptive material 2, and the attic 3 is forcedly aerated by the fan 10 in the daytime and the absorptive and desiccant 2 is absorbed. The water absorbed by the above is vaporized, and the attic 3 is cooled by latent heat of vaporization of the water.

[Other Embodiments] The types of the plate 1 and the moisture absorbing / releasing material 2 can be appropriately selected from known ones, and a specific means for integrally attaching the moisture absorbing / releasing material 2 to the plate 1 is also available. It can be appropriately selected from known ones. The form of use of the base plate can be changed appropriately.

It should be noted that reference numerals are added to the claims of the utility model for convenience of comparison with the drawings, but the present invention is not limited to the configuration of the accompanying drawings by the entry.
