Description

[Detailed description of the invention] [Technical field] The present invention relates to the structure of an opening in a fabric foundation that can improve the ventilation efficiency of the underfloor space by arranging an air guide pipe with one end located at the back of the opening in the fabric foundation. .

[Background technology]

Ventilation holes are provided in the underfloor space of houses to ventilate the underfloor space, but these ventilation holes are simply holes drilled through the fabric foundation and do not provide sufficient ventilation to the center of the underfloor space. The temperature in the underfloor space is high,
There is a problem that condensation occurs.

[Purpose of invention]

The present invention is based on the use of an air guide pipe, and aims to provide a structure for a cloth foundation opening that can solve the above-mentioned problems.

[Disclosure of invention]

An embodiment of the present invention will be described below based on the drawings.

1 to 3, the structure of the cloth foundation opening of the present invention is such that an opening 9 is provided in the cloth foundation 3 surrounding the underfloor space 2, and an air guide pipe 6 is arranged extending from the back of the opening 9 into the underfloor space. ing.

The under-floor space 2 is provided below a room in a house, and has a floor body 23 supported by a main drawer 21 and a joist 22.
It is a space surrounded by a cloth foundation 3 surrounding the periphery, and a subfloor surface 10 below the floor body, and the cloth foundation 3 has an opening that allows the underfloor space 2 to be conducted to the outside as described above. 9 is provided.

In this embodiment, the openings 9 are formed as rectangular through-holes in the cloth foundation 3 that sandwich the underfloor space 2. Further, a ventilation plate 5 is attached to the opening 9, and the ventilation plate 5 is provided with a ventilation hole 4.

The air guide pipe 6 has a rectangular cylindrical body and has an upper surface 2.
5. Both the lower surface 26 and its side surfaces 27, 27 are formed by the ventilation material 7 having a mesh shape. Thereby, the air guide pipe 6 can ventilate between the inside thereof and the underfloor space 2 through the ventilation material 7.

In this embodiment, the air guide pipe 6 connects the opposing openings 9 with each other. Both ends of the air guide pipe 6 are inserted from the back side of the opening 9 to form an air guide pipe 6 in which one end 12 is located at the back of the opening 9 and the other end 13 extends into the underfloor space 2. . Further, in this embodiment, the air guide pipe 6 is divided into three parts, with the end air guide pipes 6b, 6b fitted on both sides of the middle air guide pipe 6a, and the middle air guide pipe 6a is provided with a support base 29. It is placed on the subfloor surface 10 via.

Also, inside the air guide pipe 6, there is a first baffle plate 31 located approximately in the center of the underfloor space 2, which is perpendicular to the direction of the air guide pipe and spans horizontally between both side surfaces 27, 27.
On the other hand, a second baffle is provided between the baffle plate 31 and the opening 9, extending inward from the upper and lower surfaces 25, 26, inclined toward the opening, and vertically opposed to each other with a gap in between. Boards 32, 32 are provided, and the second baffle board 3 is provided on both sides 27, 27.
2 and 32, and the third
baffle plates 33, 33 are attached. The baffle plates 31, 32, and 33 facilitate the introduction of outside air into the underfloor space.

However, some of the outside air flowing into the air guide pipe 6 from the opening 9 through the vent 4 of the ventilation board 5 passes through the ventilation material 7 and is released into the underfloor space 2, and the majority of the air flows inside the air guide pipe 6. Go straight ahead. By going straight, the wind pipe 6
The outside air flowing near the side surfaces 27, 27 collides with the third baffle plates 33, 33, and the direction of the flow is changed by the collision, and the air flows toward both sides of the air guide pipe 6. and is released into the underfloor space 2. Furthermore, the air flowing through the upper and lower surfaces 25 and 26 passes through the ventilation material 7 as well as the third baffle plates 33 and 33 due to the collision with the second baffle plates 32 and 32, and passes through the underfloor space 2.
It is released above and below. Also, the outside air flowing through the center can be discharged to the sides of the air guide pipe 6 by the first baffle plate 31, and the outside air flowing in through the opening 7 can be efficiently introduced into the underfloor space 2. Note that the outside air flowing in from the other opening 7 also flows through the air guide pipe 7.
It can be introduced into the underfloor space 2 through.

In FIG. 4, one end 12 of the air guide pipe 6 opens at the back of the opening 9 at a distance slightly from the back of the cloth foundation 3, and the other end 13 passes through the subfloor surface 10 and the other end 13 opens into the underfloor space 2.
Another embodiment in which the opening is shown is shown below. The air guide pipe 6 is provided with a ventilation material 7 inside the floor subsurface surface 10 and near the opening at the other end 13, so that the outside air flowing through the air guide pipe 6 efficiently exchanges heat with the floor subsurface surface 10 and is cooled. The air can be discharged into the underfloor space 10.

As shown in FIG. 5, the opening 9 may be formed circularly and a circular ventilation plate 5 may be attached.

[Effect of idea]

In this way, the structure of the fabric foundation opening of the present invention is that an opening to which a ventilation plate is attached is provided in the fabric foundation that surrounds the underfloor space, and one end is located at the back of the opening, and the other end is an air guide pipe that extends into the underfloor space. By providing a ventilation pipe with a ventilation material that allows ventilation between the airflow pipe and the underfloor space, ventilation can be carried out naturally even in the center of the underfloor space, and the inside of the underfloor space can be ventilated. It can remove moisture, prevent condensation, and improve ventilation efficiency.
