Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) This invention relates to a building ventilation structure, and more particularly to an air circulation ventilation structure within each exterior wall panel of a building and inside the building.

[Conventional technology]

In order to prevent condensation and to prevent deterioration of the durability of the building structure, it is necessary to allow air to circulate inside the exterior wall panels, under the floors, or in the ceiling of conventional residential buildings. Measures such as simply providing air circulation holes between the structural members that form the sealed space or providing underfloor ventilation holes on the sides of the foundation were applied to each individual structure individually.

[Problem to be solved by the invention]

However, installing these individual ventilation holes is only a local measure and does not provide an active ventilation function throughout the building. Because it was dependent on the register (ventilation hole) on the top or satush, there were many related parts and required a lot of man-hours to construct.

This invention was made in view of the above-mentioned problems with conventional building ventilation, and it provides a consistent ventilation function for each room, as well as parts of building replacement structures such as under floors, inside external wall panels, and ceilings/attics. The purpose is to provide a building ventilation structure that can be systematically obtained.

[Means to solve the problem]

For this reason, in the present invention, air circulation gaps are provided between the outer core material of the building floor panel and the half foundation or shell difference member disposed adjacent thereto. Grooves that communicate with the gaps are carved in the lower parts of the members, and air holes that communicate with the gaps are bored in the upper and lower core materials of each outer wall panel arranged on each floor panel, The outside of the half-sill or each floor difference member is provided with a foundation drainage member or each curtain plate member having air circulation holes at the lower part, and the roof nosing member or gable member is provided with air circulation holes on the lower inner side thereof. The purpose is to achieve the above objective by configuring the building's air circulation ventilation system to provide multiple air circulation holes in the horizontal plane on the edges around the ceiling for the ceiling panels on each floor. .

[Effect]

With the building ventilation structure as described above, each of the building structural parts and each room can consistently have an active ventilation function. In addition, each component is simple, so the cost is low.

〔Example〕

The present invention will be explained below based on examples.

FIG. 1 shows a vertical cross-sectional view of an essential part of an embodiment of the external wall section from the foundation to the roof of a three-story building having a ventilation system/structure according to the present invention.

(Configuration) 1 is the fabric foundation of the building, 2 is the IF floor panel, 3 is the 2F floor panel, 4 is the roof, 5 is each external wall panel, which may be painted walls,
Alternatively, a siding material may be attached to the outside. 6 shows the ceiling panels on each floor.

1) An air circulation gap G is provided between the half base 7 placed on the foundation/IF floor fabric l11 and the outer end core material 8 of the IF floor panel 2, and the half base 7 and the floor panel core There is a gap G at the bottom of material 8.
A groove C that communicates with the gap G is carved, and an air hole H that communicates with the gap G is bored in the core material 5a at the lower end of the outer wall panel 5. A basic drainer 8 made of vinyl chloride steel plate is provided in the corresponding part of the groove C on the outside, and an air hole H is provided at the lower part of the base drainer 8, and the external air A flows through the air hole H9, the groove C9, the gap G, and the core material 5a. In addition, the air A under the floor 9 inside the outer wall panel 5 is also circulated/ventilated through the air holes H, and the air A in the interior under the floor 9 also merges with the outside air flow and is circulated/ventilated upwardly inside the outer wall panel 5.

2) There is an air circulation gap G between the outer end core material 3a of the IF ceiling/2F floor panel 3 and the girth difference 10, similar to the space between the half foundation 7/core material 2a.
Further, grooves C communicating with the gap G are carved in the lower part of the core material 3a and the barrel difference 10, respectively. Both of these members 3a.

Each lower/upper end core material 5a of each of the upper/lower outer wall panels 5 of 10 is provided with air holes H communicating with the gap G.

A curtain plate 11 made of vinyl chloride steel plate is attached to the outside spanning the upper and lower outer wall panels 5, and has an air hole H in its lower part. Therefore, the external air A flows through the dashed line path H-
Flow/ventilation is carried out upwardly within the exterior wall panel 5 through C-G-H.

On the other hand, a plurality of air holes H are continuously bored in the flat part of the surrounding edge 13 for the ceiling panel 6 of the IF room 12, and the air A in the room 12 passes through the air holes H. Then, together with the air A in the attic 14, it passes through the groove C and joins with the external air flow A at the gap G, and passes through the upper air hole H to upwardly circulate/ventilate the inside of the outer wall panel 5.

3) 2F Ceiling/Attic Finally, an air hole H is bored in the core material 5a at the upper end of the outer wall panel 5 of the 2F ceiling to guide the rising air in each of the lower outer wall panels 5 to the attic 15. In addition, the surrounding edge 13 for the ceiling panel 6 of the room 12 on the second floor is
Similar to the IF ceiling section, a plurality of air holes H are provided,
The air in the room 12 is guided to the attic space 14 and the attic space 15.

On the other hand, a nose shield (or gable) 17 made of vinyl chloride steel plate is installed to cover the head connecting member 16 of the roof 4, and is bored inside the lower part of the bridge to suck outside air A through a hole H into the attic space 15. Provide circulation/ventilation.

As described above, in the 3F building of this embodiment, each of the outer wall panels 5 from the building foundation 1 to the roof 4 is
The interior is not only exposed to outside air, but also to the floor 9 and each room 12. Since the air in each attic 14 is systematically and consistently distributed/ventilated to the attic 15 space, the ventilation function is extremely reliable.
The conventional independent ventilation means on the indoor side can be omitted.

(Other Examples) Although the above example shows the national side in the case of a 3rd floor building,
Of course, the present invention is not limited to this, and the shape and quantity of each gap G, groove C, and each air hole H, as well as the basic drainage 8. Curtain board 11, gable 17 and ceiling edge 1
The shape of the third grade is not limited to only the country side, and various modifications can be used.

〔Effect of the invention〕

As explained above, according to the present invention, since the outside air of the building and the air inside the nine rooms under the floor, the ceiling, the attic, etc. are consistently circulated/ventilated through the exterior wall panels, each component is It is simple and provides an effective ventilation function at low cost.
