Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation structure and a ventilation member for a wall or floor of a structure constituting a space, and more particularly to an indoor wall of a building, an inner wall of a storage space of a building, and a tatami base. The present invention relates to a ventilation structure suitable for ventilation in an air conditioner or the like, and a ventilation member suitably used for ventilation of a tatami ground.

[0002]

2. Description of the Related Art In recent years, many buildings are constructed using airtight building materials such as concrete panels.
In such a highly airtight building, dew condensation on the surface of the wall member is a major problem.

That is, in a highly airtight building, it is difficult for the water vapor generated in the room to escape to the outside. Therefore, the water vapor generated in the room passes through the decorative material on the wall surface and reaches a building material constituting the wall surface, for example, a concrete panel. If the temperature difference between the concrete panel and the room is large,
This water vapor is condensed on the panel wall, and the cosmetic material comes off,
It causes stains, molds, and the like.

[0004] In addition, in RC concrete buildings, since it takes time for the poured concrete to dry, moisture evaporates from the wall surfaces. Therefore, dew condensation on the wall surface may occur. Further, since the concrete containing water has a low temperature, when water vapor generated in the room comes into contact with the wall surface of the concrete, dew condensation is likely to occur. For this reason, it can be said that the above-described problem caused by condensation is more likely to occur.

[0005] Therefore, in order to prevent condensation on the surface of the wall member, it is conceivable to provide a ventilation layer in order to discharge water vapor so as not to stay near the surface.

[0006]

Conventionally, this type of ventilation layer is constructed by providing a plate or the like on the surface of a wall material, providing irregularities, and mounting an interior panel thereon. Such a structure has the drawback that the construction is troublesome and the construction cost is high. The same applies to a storage space such as a closet, a closet, a storage, or the like.

When tatami is laid in a concrete building, the concrete floor c is covered with mortar m,
Tatami 6 'was laid on it (see FIG. 8). for that reason,
Water vapor that has passed through the tatami mat 6 'is condensed on the surface of the mortar m, causing mold to occur and causing the tatami mat 6' to rot, as in the case of the wall surface described above. However, no special measures have been taken in this regard in the past.

[0008] A first object of the present invention is to provide a ventilation structure capable of easily forming a ventilation layer on a wall surface.

[0009] A second object of the present invention is to provide a ventilation structure for ensuring air permeability in a tatami ground.

A third object of the present invention is to provide a ventilation member which can be used to construct a ventilation structure for ensuring the ventilation of a tatami base.

[0011]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above-mentioned object, and a first aspect of the present invention relates to a ventilation structure for a wall portion of a structure constituting a space. And a spacer panel having a concave portion communicating with at least one direction, wherein the spacer panel is disposed between the wall surface portion and a covering member covering the wall portion, and the spacer panel is disposed therebetween. A ventilation structure characterized by performing ventilation with the air is provided.

According to a second aspect of the present invention, there is provided a ventilation structure of a base of a tatami mat in a case where tatami mats are laid, wherein a spacer panel having a concave portion communicating in at least one direction, and a tatami mat is formed. A ventilation member disposed along an outer edge of at least one side of at least one tatami mat at an arbitrary position on the tatami mat surface to be provided, wherein the ventilation member has a concave portion of the space panel, and a space outside the tatami mat. The space panel is provided with a ventilation hole for communicating with the ventilation panel, and the space panel is arranged so that a concave portion thereof communicates with the ventilation hole.

According to a third aspect of the present invention, there is provided a ventilation member which is installed on a floor together with a tatami mat and communicates a space between a base of the tatami mat and a bottom surface of the tatami mat with a space above the tatami mat. The timber is provided with a plurality of holes that open along the longitudinal direction of the timber, on a surface aligned with the tatami top surface when the timber is arranged with the tatami mat, and the timber has a side surface of the tatami mat. A communication member is provided at a position below the tatami mat on a surface opposite to the tatami mat to provide communication between the space below the tatami mat and each of the plurality of holes.

In this case, the communication portion includes a second hole provided corresponding to each hole, a notch provided corresponding to each hole, and a step portion cut along the longitudinal direction of the square bar. Any one form may be sufficient.

The operation will be described.

The operation of the first embodiment will be described.

The spacer panel is disposed between the wall and the covering member covering the wall. Since the spacer panel has a concave portion communicating with at least one direction, the ventilation can be efficiently performed.

The operation of the second and third aspects will be described.

The ventilation member is arranged along one outer edge of the tatami mat. Further, the spacer panel is arranged so that its concave portion communicates with the ventilation hole of the ventilation member. Therefore, moisture and the like in the space below the tatami mat reach the ventilation member through the concave portion. Then, it is quickly discharged to the outside through the ventilation holes of the ventilation member.

The ventilation member can be formed by using, for example, a square material. That is, holes are provided in a surface that is arranged on the floor together with the tatami mat and that is aligned with the upper surface of the tatami mat and in a position below the tatami mat on a surface facing the side surface of the tatami mat. Further, a structure provided with a communicating portion for communicating both holes may be used.

[0021]

Embodiments of the present invention will be described below with reference to the drawings.

A first embodiment of the present invention will be described with reference to the drawings.

In this embodiment, as shown in FIG. 1, moisture in the lower space of the tatami 6 is guided to the ventilation member 2 by the spacer panel 1 and discharged to the upper space of the tatami 6 through the ventilation member 2.

The spacer panel 1 guides the moisture in the lower space of the tatami 6 (the space between the base of the tatami and the bottom of the tatami) to the ventilation member 2. The spacer panel 1 is shown in FIG.
As shown in FIG. 2, a plate-like member is provided with convex portions 10 on both sides thereof over the entire surface. A region between the convex portions 10 constitutes a concave space 11 communicating with at least one direction (FIG. 3).
reference). At the time of construction, the spacer panel 1 is provided with the concave space 11.
Are arranged in a direction crossing the longitudinal direction of the ventilation member 2. Since the exhaust resistance in the concave space 11 is small, the moisture in the space below the tatami mat can easily reach the ventilation member 2 through the concave space 11.

The ventilation member 2 constitutes a discharge passage for discharging the moisture guided by the spacer panel 1 to the space above the tatami mat 6. In addition, the ventilation member 2
Are arranged side by side with the tatami mat 6 and also serve as a floor interior material together with the tatami mat 6. However, in order to provide the ventilation member 2 separately from the tatami mat 6, it is necessary to make the shape and size of the frame member constituting the house different from the conventional one.
However, this is an obstacle to implementing the present invention. In this embodiment, in order to avoid such a situation, the ventilation member 2 is built in the outer edge portion of the tatami 6 in advance.

As shown in FIG. 4, the ventilation member 2 is made of a square material. Tatami body part 6
A plurality of ventilation holes 20 that are open along the longitudinal direction of the square bar are provided on a surface aligned with the upper surface of the square bar (see FIG. 1). A second ventilation hole 21 is provided on a portion of the square member facing the side surface of the tatami main body portion 60 below the tatami main body portion 60. Then, the ventilation hole 20 and the ventilation hole 2
1 communicates with the inside of the ventilation member 2. Thus, the moisture in the lower space of the tatami mat enters the ventilation member 2 through the ventilation hole 21 and is discharged to the upper side of the tatami through the ventilation hole 20. In FIG. 4, only a part of the communicating portion connecting the two ventilation holes 20 and 21 is illustrated.

The dimensions of the ventilation member 2 are as follows.
It is determined in consideration of the fact that it is built into the outer edge portion of (or placed side by side with a tatami mat). That is, the length L is made to coincide with the long side of the tatami mat. The height H is the same as that of a normal tatami mat. Although the thickness W is not particularly limited, considering the appearance of the tatami 6,
The value in which the portion incorporating the ventilation member 2 is substantially equal to the width of the outer edge portion of a normal tatami mat is set.

The tatami 6 has a tatami main body 60 that is thinner than a normal tatami by the thickness of the spacer panel 1.

The operation of the spacer panel 1 and the ventilation member 2 in this embodiment will be described.

The recessed space 11 of the spacer panel 1 has a small airflow resistance. Therefore, the moisture in the lower space of the tatami 6 can easily reach the second ventilation hole 21 of the ventilation member 2 through the concave space 11. Then, the air is discharged from the ventilation hole 20 through the communication portion in the ventilation member 2.

As described above, according to this embodiment,
By forming a ventilation layer on the lower side of the tatami, it is possible to reliably discharge moisture to the upper side of the tatami and prevent dew condensation. Further, the construction work for forming the ventilation layer is easy. Further, when the ventilation member is built in the tatami mat, it is not necessary to change the dimensions of the frame member of the house.

In this embodiment, emphasis is placed on not changing the shape and dimensions of the frame members of the house, and the thickness of the tatami body 60 is reduced by the thickness of the spacer panel. But,
It is not necessary to reduce the thickness of the tatami mat if the height of the threshold or the like can be increased by the height of the spacer panel. A tatami mat of the same size as the conventional one can be used.

It goes without saying that the ventilation member 2 may have any shape and size as long as the shape and dimensions of the tatami and frame members can be changed.

The specific shape of the ventilation member 2 is not limited to that shown in FIG. For example, as in the case of the ventilation member 2 'shown in FIG. 5, a notch 22 may be provided for each ventilation hole 20 in the lower part, and the second ventilation hole 21 may be provided here. In such a structure, there is little possibility that the pipe portion connecting the ventilation hole 20 and the ventilation hole 21 is clogged by dust or the like.
Also, even if it is jammed, it is easy to remove dust and the like. In addition, since the ventilation member 2 is symmetrical, either the left or right side may be installed facing the tatami main body 60. Therefore, the work efficiency of the work of attaching the ventilation member 2 to the tatami mat 6 (or the work of installing the ventilation member between the tatami mats) is higher than that of the ventilation member having the asymmetric structure (for example, the structure of FIG. 4). Furthermore, moisture from either the left or right side,
The air holes 21 can be reached. Therefore, the efficiency of discharging moisture is higher. Since the ventilation member 2 is arranged along the outer periphery of the tatami, the ventilation member 2 can be arranged not only at the outer periphery of the room but also at the center of the room. This high discharge efficiency is more remarkable when the ventilation member 2 'is installed near the center of the room.

The ventilation member 2 "shown in FIG. 6 is an example in which a stepped portion 23 cut out along the longitudinal direction of the square member is provided, and a second ventilation hole 21 is provided on the surface of the stepped portion 23. In such a structure, there is little possibility that a pipe portion connecting the ventilation hole 20 and the ventilation hole 21 is clogged by dust or the like.

The ventilation member 2 having the structure shown in FIG.
Since it can be manufactured simply by making a hole in a square bar with a drill, it is advantageous in terms of cost. In this case, if the ventilation hole 21 is made to penetrate to the opposite side surface, it does not matter whether the left or right side surface faces the tatami as in the case of the ventilation member 2 ′. Therefore, the efficiency of discharging moisture is increased as in the case of the ventilation member 2 '(FIG. 5).

In the above embodiment, the ventilation member 2 is
Was built into the long side. However, it may be built in the short side of the tatami 6. Further, the ventilation member 2
Need not necessarily be built into the tatami mat 6. The tatami mat 6 and the ventilation member 2 may be configured as separate members.

In the above-described embodiment, the ventilation member 2 is built in the tatami mat. In addition, it is conceivable to provide a ventilation hole in a threshold or the like so that the threshold itself functions as a ventilation member.

The embodiment described above aims at discharging moisture in the space below the tatami mat. However, the action of discharging moisture by the above-described spacer panel 1 is also effective for ordinary house walls and floor materials. For example, as shown in FIG. 7, the spacer panel 1 may be arranged between the floor material 3 and the inner wall material 5 of the house and the concrete c. When the heat insulating panel 4 is used, the spacer panel 1 is installed between the heat insulating panel 4 and the concrete c. The same spacer panel as that of the first embodiment can be used. By doing so, the floor material 3, the inner wall material 5
And the moisture in the clearance space with the concrete c can be quickly discharged.

In the above-described embodiment, mainly the ventilation in the room and the ventilation in the tatami floor of the building have been described, but the present invention is not limited to this. For example, the present invention can also be applied to a storage space in a room such as a closet, a closet, and a storage. In addition, the present invention is not limited to buildings, and can be applied to indoors of moving bodies such as ships and vehicles. Further, the present invention can be applied to a storage device such as a container.

[0041]

According to the present invention, the inner wall surface of a building and / or
Or, by attaching a spacer panel to the floor surface, the inner wall surface and / or the bottom surface of the storage space,
A ventilation layer can be constructed, and dew condensation on the wall surface can be prevented. Therefore, it is possible to avoid occurrence of various problems due to dew condensation.

In addition, according to the present invention, by installing the spacer panel and using the ventilation member, it is possible to improve the air permeability of the tatami base. As a result, dew condensation on the tatami mat base can be prevented, and various problems due to dew condensation can be avoided.
