Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof in a hot spring bath, a roof of a hot water pool, etc., where dew condensation easily occurs.

[0002]

2. Description of the Related Art Conventionally, an inner layer material such as a ground board is laid on a support member such as a main house, and a mounting member such as a rafter orthogonal to the support member is provided, and a roof plate is roofed on the mounting member. Is commonly used.

However, such a roof is
When used in a hot water pool, etc., the humidity in the room is large and the temperature difference between the room and the outside air is large.Therefore, moisture enters the roof from the room through the joints of the inner layer materials and causes dew condensation. There is a problem that paint such as wood and rafters may peel off and rust, or if the inner layer material is wood, it may be corroded and corroded.

[0004]

DISCLOSURE OF THE INVENTION The present invention is intended to solve the above-mentioned problems and prevents moisture from invading the inside thereof, and also improves the heat insulating property, so that it can be used in a bath or a warm water pool. Even if it is used, it is intended to provide a roof which is less likely to cause dew condensation and has less heat loss in the room.

[0005]

In order to achieve this object, the roof of the first invention comprises a support member (1) such as a purlin on a support member (1).
Laying a non-breathable plate (2) provided with a rising part (2a) and a peripheral part (2c) bent outward from the tip of this rising part (2a) at both ends, and this non-breathing plate (2) The inner layer material (3) is overlaid on top of it, and the adjacent non-breathable plate (2) is placed on the upper surface portion (15c) of the rafter (15) having the flange portion (15a) arranged on the support member (1). ) Is overlapped, the rafters (15) are fixed to the support member (1), and the roof plate (14) is roofed on the rafters (15).

Further, the roof of the second invention is the specific invention of the first invention, and further, the retaining plate (7) and the upper rafter secured by the retaining plate (7) on the peripheral edge portion (2c). (10) and the presser plate (7) is fixed with a fixing tool, and the upper inner layer material (12) is further disposed on the upper rafter (10) to dispose the inner layer material (3) and the upper inner layer. An air layer (13) is formed between the material (12) and the roofing board (14) on the upper rafter (10).

[0007]

[Operation] According to the first invention, the non-breathable plate is laid on the support member, and the inner layer material is laid on the support member. As a result, the two ends of the non-breathing board adjacent on the rafters are
Compared with the conventional configuration that is fixed on the
It is possible to accurately block moisture at the overlapped part of the edge.
Ri, baths, even moisture is very high places such as heated pool, moisture through the joint and the inner layer member can be prevented from reaching the interior of the roof. Therefore, even if it is applied to a roof that easily condenses inside, such as a hot spring bath or the roof of a wet water pool, it does not easily rust or corrode the roof plate or the like due to condensation, and it has excellent heat insulation properties. This has the effect of reducing loss.

According to the second invention, in addition to the operation of the first invention, since the upper rafter can be arranged on the rafter and an air layer can be formed in the vertical direction of the rafter, this air layer Acts as a heat insulating layer, and even if some moisture leaks to the air layer, it is difficult for dew to condense. Moreover, it has the effect of improving the sound insulation function.

[0024]

According to the first aspect of the present invention, the non-breathable plate is laid on the support member, the inner layer material is laid on the non-breathable plate, and the contact point, that is, the peripheral portion of the non-breathable plate is on the upper surface of the rafter. Since they are overlapped , both ends of the non-breathing board that is adjacent to the rafters are separated.
Compared with the conventional configuration that is fixed on the
It is possible to accurately block moisture at the overlapped part of the edge.
Ri, baths, even moisture is very high places such as heated pool, moisture through the joint and the inner layer member can be prevented from reaching the interior of the roof.

Therefore, even if it is applied to a roof where hot water such as a hot spring bath or a hot water pool roof is subject to dew condensation, the roof plate is not likely to rust or corrode due to dew condensation, and has excellent heat insulation. This has the effect of reducing heat loss.

According to a second invention, the first invention
In addition to the effect , an upper rafter can be placed on the rafter, and an air layer can be formed in the vertical direction of the rafter, so this air layer becomes a heat insulating layer, and even if some moisture leaks to the air layer, dew condensation will occur. Hard to do. Moreover, it has the effect of improving the sound insulation function.
