[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the roof structure of a building, and more specifically, the present invention relates to the roof structure of a building dyeing structure, and more specifically, the invention relates to the roof structure of a building dyeing structure, and more specifically, the roof structure of a dyed building is a structure that easily fills the upper part of a building, including the attic surface (ceiling surface). This allows dew condensation, adhering moisture, smoke, odors, etc. to be smoothly removed to the outside. This invention relates to improvements in the roof structure of buildings, particularly simple buildings and temporary buildings, that require ventilation in a broad sense.

[Conventional technology]

Traditionally, this kind of simple Pi buildings and temporary buildings3
For example, it can be used to prevent smoke that easily fills the upper part of an indoor building, such as an outdoor simple building used for cueing a garden bar, or to prevent moisture from building up in a relatively large building, such as an outdoor temporary bathhouse. General natural ventilation using convection is not sufficient to achieve a ventilation effect in a broad sense in buildings, etc., where odors must be eliminated individually, such as in animal husbandry books. ventilation effect 4
7. Therefore, in normal cases, the correlation between the indoor space volume used for J and the installation location is considered, and a powered ventilation fan with sufficient exhaust capacity is installed accordingly. .

(Problem to be Solved by the Invention) However, in the case of conventional ventilation means in buildings that use power ventilation fans as described above, it is necessary to specify the installation position of the applicable power ventilation fan. In addition, the space volume is ventilated in each installed part, thereby promoting convection throughout the interior and achieving a ventilation effect. Not only is it difficult to provide ventilation, that is, quick ventilation, but it also requires a constant drive of a powered ventilation fan, which increases costs.

This invention is an attempt to improve these conventional problems, and its purpose is to improve the roof structure of a building and to utilize the suction effect of outside air flowing on the roof surface to improve the structure of the attic. Ventilation can be performed from the whole surface, and by extension, from the entire indoor surface. The object of the present invention is to provide a roof structure for this kind of building.

[Means to solve the problem]

In order to achieve the purpose of navigation, the roof structure according to the present invention has a predetermined roof slope, each purlin material is constructed at predetermined intervals parallel to the ridge direction, and each of these 1) 1 A roof (hut) structure is formed by each vehicle timber installed at predetermined intervals perpendicular to the roof timbers, and a four-piece board part,
For this installation, a ventilating roof plate consisting of a rising oblique side rising from the base plate and a hanging extension part extending this rising oblique side is provided, and the above-mentioned 8. In heavy timber I-, the lower part of each ventilation roof board is attached to the base plate, and the extension part on the upper part is attached to the base plate, and the lower part of the L part is attached to the base plate. The ventilation roof panels are horizontally roofed one after another so as to overlap with each other, and a suction space is formed between each ventilation roof board that communicates with the internal space between each rafter. A ventilation ceiling board consisting of a hanging part hanging down on one side of the ceiling face board part and a standing 4-inch end board part on the other side is installed,
When attaching the top and bottom panels of each ventilation ceiling panel, the hanging part on the lower side on the top side should be inserted through a gap inside the ζγ chirped end plate on the bottom side. A suction space communicating with the interior space is formed between each ventilation ceiling plate by sequentially extending horizontally and n-fold so as to overlap each other.

[For production]

That is, in this invention, the flow of outside air that blows up and blows through along the roof slope creates a negative pressure in the suction space between each ventilation roof plate formed on the roof surface of the second most layer. The internal air generated and filling the ceiling surface of the lowest floor is sucked in evenly through the suction space created by opening the gap between each ventilation ceiling panel, and is then discharged to the outside through the internal space and the suction space. At the same time, the condensation 9 of moisture on each ceiling panel surface and the adhesion on the upper part are allowed to flow down along each surface, and are received sequentially on the inner surface of the lower tier, and from the hanging part of the lowest tier. It can be leaked outside.

〔Effect of the invention〕

As detailed above, according to the present invention, each purlin material is constructed at predetermined intervals parallel to the ridge direction with a predetermined roof slope set, and A roof (hut) structure is constructed by each rafter installed at a predetermined interval, and the mounting is carried out on the base plate, the rising oblique part rising from the base plate, and the rising hypotenuse part. A ventilation roof board consisting of an extended hanging extension is provided, and is located on each rafter, and the lower part of each ventilation roof board is attached to the base plate, and the part of the ventilation roof board is attached to the bottom side. By installing the extension part on the upper stage side and the lower part side in order so that it overlaps the base part,
Between the phases η of each ventilation roof board of the stiff roof, a suction space is formed which communicates with the internal space between each rafter. Heavy down-
A ventilation ceiling board is provided consisting of a hanging part and a standing end plate part with a vertical extension on the other side, and a ceiling face plate part of each ventilation ceiling board is attached to each side of the main building material. At the same time, the lower part of the 1st floor on the lower side of the upper level is overlapped with the inner side of the standing end plate on the upper side of the lower level with a gap in between, so that even this S can be achieved. Since a suction space that communicates with the interior space is formed between each of these ventilation ceiling panels, it is generally formed on the roof surface of the top layer by the flow of outside air that blows up and blows through along the roof slope. Negative pressure is generated in the suction space between each ventilation roof panel, and the inside air that fills the ceiling surface of the lowest floor is averagely drawn from the suction space created by opening the gap between each ventilation ceiling panel. This allows air to be sucked into the ceiling and exhausted to the outside through the interior space and the suction space. In addition, odors, etc. can be expelled quickly and smoothly, resulting in extremely good ventilation.

At the same time, condensation of moisture that tends to form on the surface of each ceiling panel, as well as any adhesion on the upper part, is caused to flow down along each surface, and is sequentially received on the inner surface of the lower side. , because it can finally flow outside from the lowest hanging part, it is possible to effectively eliminate unpleasant dripping of condensed water and deposits from the ceiling surface, and it is also possible to effectively eliminate the unpleasant dripping of condensed water and deposits from the ceiling surface. ``Secondly, by installing a net to prevent thick objects from entering, it is possible to prevent fallen leaves from entering each suction space, and since it does not use a powered ventilation fan for ventilation, equipment costs and maintenance are reduced. It has excellent features such as low cost, relatively simple overall structure, and can be provided easily and inexpensively.
