Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation structure for a ceiling of a building.

[0002]

2. Description of the Related Art Conventionally, the ventilation of a building such as a house is not limited to forced ventilation by a ventilation fan or the like in a kitchen or bathroom, or natural ventilation by a window, etc. Since the ceiling of the house was isolated from the outside of the building by the outer wall, the ceiling was not ventilated.

[0003]

However, warm air with a high water content, which is trapped during the rainy season, and air, which has a high water content due to the infiltration of water and water vapor from the floors above and below the ceiling, are used in winter. There is a problem that it may be cooled and dew on the ceiling.

Further, since warm air having a high water content stagnates,
There was a problem that molds and the like could easily propagate on the ceiling.

Further, since there is no place for stagnant air to flow in the ceiling above, not only the noise from the upper and lower floors reverberates between the floor plate above and the ceiling plate below, but there is no place for the sound to escape. There was a problem that it was difficult to attenuate and the sound insulation of the upper and lower floors was poor.

The present invention has been made in order to solve the above-mentioned problems, and provides a ventilation structure for the ceiling above which it is possible to prevent the formation of condensation on the ceiling to suppress the growth of mold and to improve the sound insulation of the upper and lower floors. The purpose is to do.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the ventilation structure for the ceiling of the present invention is shown in FIG. 1 and will be described below. FIG. 1 is a perspective view of a main part with a part of a ventilation structure in the ceiling behind being cut away.

The ventilation structure of the above-ceiling 1 has a ventilation port 3 provided in an outer wall portion 2 located in the above-ceiling space 1. This ventilation port 3 is an upper end of a lower floor wall panel 21 constituting the outer wall portion 2. It is made by utilizing a nut screwing operation opening portion 211 provided in the portion. A ventilation draft 4 (edge frame) is attached to the ventilation port 3. Further, a drainer barrel cover 5 is attached to the outside of the ventilation port 3.

The opening 211 for screwing operation of the nut is
It is a through hole for work for screwing the nut 7 into the long bolt 6 for connecting the lower floor wall panel 21 and the upper floor wall panel 26. The opening 211 for screwing operation of this nut is surrounded by the upper lateral core material 212 of the lower floor wall panel 21, the lower frame member 213, and both side frame members (not shown in the figure). The outer side plate 214 and the inner side plate 2 of the lower floor wall panel 21
The ventilation port 3 is formed by closing the hollow portion 216 sandwiched by 15.

The ventilation gullet 4 is for preventing small animals from invading the ceiling space 1 from the ventilation port 3 by the blade 41 thereof. The size of the ventilation gutter 4 is such that the ventilation port 3 is just edged, and its depth is such that it does not hit the nut 7 screwed to the long bolt 6. If necessary, the blade 41 may be opened and closed, and a bimetal or the like may be used to open and close or adjust the opening degree depending on the temperature difference and humidity difference between the ceiling 1 and the outside of the building.

The drainage barrel cover 5 hides the barrel gap 8 interposed between the lower floor wall panel 21 and the upper floor wall panel 26, and also serves as a drainer. It is attached between the lower floor exterior material 22 and the upper floor exterior material 27 which are attached to the panel 21 and the upper floor wall panel 26, respectively. At the upper end portion of the drainage barrel cover 5, a mounting portion 51 fixed to the lower portion of the upper floor wall panel 26 with a screw 91 or the like is provided. The mounting portion 51 is hidden by the upper floor exterior material 27. On the lower side of the mounting portion 51, a downward slope is projected to the outside of the lower floor exterior material 22,
The water that has flowed down along the upper floor exterior material 27 and is flowing down the lower floor exterior material 2
A running water guide portion 52 that guides the outside of 2 is provided. Further, on the lower side thereof, the body difference 8 and the ventilation opening 3 are hidden so as not to be seen from the outside front side so as not to impair the aesthetic appearance, and a cover portion for preventing water from entering through the ventilation opening 3. 53 is provided. Further, on the lower side thereof, that is, on the lower end of the drainage barrel cover 5, there is a drainer that allows the water that has flowed down from the flowing water guide portion 52 through the cover portion 53 to flow outside the lower floor exterior material 22. A drainer 54 is provided.

The above-mentioned constituent members of the ventilation structure for the ceiling are assembled as follows. First, the lower frame member 2 is inserted into the screwing operation opening portion 211 of the nut of the lower floor wall panel 21.
13 and frame members on both sides (not shown in the figure) are attached to form the ventilation port 3, and the ventilation hood 4 is attached to the ventilation port 3 with a screw 92 or the like. After that, the upper floor wall panel 26 is erected on the lower floor wall panel 21 thus erected via the floor 93 and the body difference 8, and the long bolt 6 and the nut 7 are connected. Next, the lower floor exterior material 22 is attached, the drainage barrel cover 5 is attached, and a packing (not shown) or the like is interposed between the drainage barrel cover 5 and the attachment portion 51 of the upper drainage exterior material 27. Attach. Then, by attaching the ceiling 94, a ventilation structure for the ceiling ceiling 1 is completed.

According to the above embodiment, since the ventilation port 3 is provided in the outer wall portion 2 located on the ceiling back 1, the ventilation port 3 is provided.
The outside air flows into the attic 1 via the air and the air flows out from the attic 1, so that the air does not stagnant in the attic 1.
Therefore, the growth of mold is prevented by preventing the dew condensation on the attic 1, and the sound is not trapped on the attic 1, and the sound insulation of the upper and lower floors is excellent.

According to the above embodiment, the lower floor wall panel 21 and
Attach the nut 7 to the long bolt 6 for connection with the upper floor wall panel 26.
Screw operation of a nut that is a through hole for work for screwing
The action opening 211 is used as the ventilation port 3.
So, a separate ventilation port is provided in the outer wall part 2 located in the above-ceiling space 1.
No need.

Further, in the above embodiment, the ventilation gutter 4 is attached to the ventilation port 3, but the invention is not limited to this, and the ventilation grate 4 may not be attached. Ventilation dust may be provided inside the drainage barrel cover 5.

Further, in the above embodiment, the ventilation port 3
Although the drainage barrel difference cover 5 is attached to the outside of the above, it is not limited to this, and it goes without saying that the drainage barrel difference cover 5 may not be attached.

Furthermore, in the above embodiment, the drainage barrel cover 5 is composed of the mounting portion 51, the flowing water guide portion 52, the cover portion 53 and the drainage portion 54, but the invention is not limited thereto. However, if the body difference 8 and the ventilation port 3 are hidden from the outside front so as not to impair the aesthetics and water can be prevented from entering from the ventilation port 3, It may be configured to.

Further, in the above-mentioned embodiment, the case of the house by the panel construction method has been described, but the present invention is not limited to this, and it can be applied to the house by the conventional construction method.
