Description

TECHNICAL FIELD The present invention relates to a roof structure of a building, and more specifically,
Ventilation in a broad sense that easily fills the upper part of the building, including the back side of the building and the ceiling side, and also allows the condensation, moisture, smoke, odor, etc. on the same side to be smoothly removed to the outside. Buildings with action, especially simple buildings, relate to the improvement of the roof structure of temporary buildings.

[Conventional technology]

Smoke in buildings such as barbecue houses that tend to be filled with smoke, moisture in temporary baths where water vapor tends to concentrate at the top of buildings, or relatively large animal pens that tend to fill the entire building When it is necessary to eliminate each odor, general ventilation using only convection cannot provide sufficient ventilation, so the correlation between the indoor space volume to be applied and the installation position must be correlated. Considering this, a power ventilation fan with sufficient discharge capacity is provided to obtain the forced discharge effect.

[Problems to be Solved by the Invention]

However, in the case of a ventilation means in a conventional building that uses a power ventilation fan, the space volume is ventilated for each installation part, which promotes the convection of the entire interior, thereby exerting a ventilation effect. It was difficult to quickly provide uniform and simultaneous ventilation of the entire volume. Further, since it is necessary to constantly drive the power ventilation fan, there is a problem in that it is expensive.

Further, Japanese Patent Application Laid-Open No. 62-63749 discloses an invention of a roof structure material, but since the shielding member has a guide plate, it is not suitable for a gently sloping roof, and the shielding member faces the pillar. There is also a problem in the strength of the roof as a whole.

The present invention is intended to improve such conventional problems, to improve the roof structure in a building, to utilize the suction effect of the outside air flowing through the roof surface, It is an object of the present invention to provide a ventilation roof structure for a building that can perform ventilation.

[Means for Solving the Problems]

A plate is provided, and on each of the lumbers, the lower side mounting board portion on the lower side of the ventilation roof board is mounted, and the upper extension is extended so that it overlaps with the upper side mounting board portion. Sequentially roofing, constructing a suction space part that communicates with the internal space part between each hanging lumber between each ventilation roof plate, and further, the ceiling face plate part in the center part and one side part of the ceiling face plate part. Stand up to the hanging part and the other side of the ceiling plate. A ventilation ceiling plate consisting of a rising end plate portion is provided, and a ceiling surface plate portion of each ventilation ceiling plate is attached to each of the main material sides, and a hanging portion on the lower side of the upper stage is a rising end on the upper side of the lower stage side. The inner side of the plate portion is sequentially laterally overlaid so as to be overlapped with a gap, and a suction space portion communicating with the internal space portion is formed between the ventilation ceiling plates.

Further, the invention of claim 2 is one in which each ventilation roofing board is laterally roofed on the upper part of each rafter near the ridge, and the remaining portion is laterally roofed. is there.

Further, in the invention of claim 3, a net for preventing foreign matter intrusion is stretched on each ventilation roof plate.

[Work]

That is, in the present invention, a negative pressure is generated in the suction space between the ventilation roof plates formed on the roof surface of the uppermost layer due to the flow of the outside air blown up along the roof slope and passing through, The inside air filled in the ceiling surface of the lowermost layer can be sucked on average from the suction space portion where the gaps between the ventilation ceiling plates are opened, and can be discharged to the outside through the inner space portion and the suction space portion.

At the same time, including rainwater that flooded from the space of the ventilation roof plate,

〔The invention's effect〕

As described in detail above, according to the invention of claim 1, a predetermined roof slope is set, and each main building material that is installed in parallel at a predetermined interval in parallel with the ridge direction is orthogonal to each main building material. The roof assembly is made up of the hanging lumbers that are erected at predetermined intervals, and is composed of the mounting board portion, the rising slope portion raised from the mounting board portion, and the extension portion extending from the rising slope portion. In addition to installing the lower ventilation board on the lower side of the ventilation roof board on each lumber, the mounting extension on the upper side overlaps the mounting board on the upper side. In this way, by laterally roofing, a ventilation space that communicates with the internal space between the hanging lumbers is formed between each of these ventilation roof boards, and further, with a ceiling face plate at the center. , And a hanging part hung on one side of this ceiling plate, Provide a ventilation ceiling plate consisting of a rising end plate part that has been raised on the other side of the well face plate part, and attach the ceiling face plate part of each ventilation ceiling plate to each main material side, and the lower part of the upper side , By sequentially laterally roofing so as to be overlapped with a gap inside the rising end plate portion on the lower side of the upper side, between each of these ventilation ceiling plates,
Since the suction space part that communicates with the internal space part is configured, the inside of the suction space part between the ventilation roof boards formed on the roof surface of the uppermost layer by the flow of outside air that is blown up along the roof slope and blows through. Negative pressure on the
Smoke, moisture, odor, etc., which fill the ceiling surface of the bottom layer, are sucked in evenly from the suction space part with the gap between the ventilation ceiling plates opened, and this is sucked in and out. It can be exhausted quickly and smoothly to the outside through the parts, and a very good ventilation effect can be obtained.

At the same time, even for dew condensation such as moisture and smoke deposits that tend to occur on the surface of each ceiling plate at this time, they are made to flow down along each surface and sequentially received on the inner surface on the lower side of the ceiling plate. Finally, since it can be made to flow out from the lowermost hanging part to the outside, it is possible to effectively eliminate unpleasant dripping of dew condensation water or deposits from the ceiling surface.

Moreover, since the ventilation roof board is fixed to the hanging wood and the ventilation ceiling board is fixed to the main building material, the strength of the roof can be sufficiently secured, so that it can be applied to a medium-scale or large-scale roof. .

In addition, according to the invention of claim 2, the ventilation structure is limited to the upper part close to the ridge on the hanging lumber, and the other parts are roofed with a normal side-roofing roof, thereby A lean roof structure can be obtained according to the scale.

Furthermore, according to the invention of claim 3, by installing a net for preventing foreign matter invasion on each ventilation roof plate, it is possible to eliminate the invasion of the fallen leaves and the like into each suction space portion, and for the ventilation action. Since it does not use a power ventilation fan, the facility cost and maintenance cost are low. At the same time, the overall structure itself is relatively simple and has many excellent features such as easy and inexpensive provision.
