DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plug structure disposed at an opening of a ventilation layer in the ventilation layer construction method in order to prevent insects, small animals, rain and snow from blowing into the opening. is there.

[0002]

2. Description of the Related Art A ventilation layer method is one of the methods for discharging water to the outside without retaining water in a wall. A ventilation layer is provided between a wall as a building body and an outer wall. In addition, a method is provided in which gaps are provided near the lower end of the outer wall, under the eaves, or near the roof eaves, and these gaps are used as air outflow / inlet ports to discharge wet air.

[0003] Further, since the ventilation layer necessarily has a portion that communicates with the outside air, rain and snow, and in some cases, insects and small animals may enter there. When rain or snow enters, the wood rots or the heat insulating function of the heat insulating material is reduced, thereby shortening the life of the house.

[0004] Therefore, a plug structure is generally arranged at the opening of the ventilation layer to prevent the intrusion of the plug structure. There are various types of this plug structure, and various improvements have been made.

[0005]

The main purpose of the plug structure is to prevent intrusion of rain, snow, etc. as described above, but of course, the inflow of air from the opening is sufficient. Must be secured. However, a structure for preventing intrusion of rain, snow, and the like, and a structure for ensuring sufficient inflow of air from the opening are not compatible with each other.

That is, if it is attempted to prevent rain and snow from entering, the amount of air flowing into the plug structure may be so small that it hardly exerts an effect. The product was being manufactured in such a way as to find points. That is, there was no ideal plug structure.

[0007]

Means for Solving the Problems In view of the above points, the present inventor has finally completed the present invention as a result of intensive research. The feature of the present invention is that two opposed flat plates are provided. What is claimed is: 1. A plug structure comprising a ventilation member having a plurality of communication holes, wherein said ventilation member is provided with a plurality of rows of ventilation holes arranged intermittently at regular intervals and at intervals. The point is that it is formed by small members.

That is, the present invention is characterized in that the ventilation member is formed by a plurality of rows of ventilation small members. Since the ventilation small members are intermittently arranged, the ventilation small members are present in the flat plate. Zones and non-zones will alternate. Then, even if the wind of rainwater blows into the small ventilation member on the entrance side and the part of the small hole is covered with water, water will drip at the place where the small ventilation member is cut. It is thought that it is harder to penetrate inside from there.

Here, the "flat plate" is a member for holding a ventilation member to be described later, and is provided so that the ventilation member is fitted in a gap between two opposed flat plates. There is no limitation on the material or structure.

The "venting member" is a member for letting the air which has reached the main body flow into the main body and for damping rainwater or the like, and is an aggregate of many small holes. In general, many structures have a shape such that a plurality of plastic cardboards are stacked in the same hole direction. In the ventilation member of the present invention, it is possible to use this conventional member. However, because of the structure of being arranged intermittently, it is necessary to cut it into several parts without arranging it as it is, and a "flat plate" is indispensable in the sense of securing a gap.

The gap may be left as it is as a gap, or another member may be arranged here.
Suitable additional members are a coarse net or a nonwoven fabric for filtering air flowing into the main body. Further, the number of the gaps may be any number, but preferably 1 to 3.

Further, the plug structure of the present invention can be installed not only at the lower end position of the outer wall of the building but also under the eaves or on the top of a large roof. Among them, the structure of the type installed on the top of the large roof conforms to the shape of the “ridge”, and if the two plug structures of the present invention are combined in a V-shape, it can be easily installed on the roof. It is suitable.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in more detail with reference to the drawings.

FIG. 1 is an exploded perspective view showing an example of a plug structure 1 for a ventilation layer opening according to the present invention (hereinafter referred to as "the present invention structure 1"). 1
Is formed by two flat plates 2 and three small ventilation members 3 disposed between the two flat plates 2.

Each of the small ventilation members 3 is a member having a large number of ventilation holes 4, and these many ventilation holes 4 are arranged so that the directions thereof are all aligned. Also three small ventilation members 3
Are arranged in parallel with each other at intervals, so that two bar-shaped spaces 5 are formed.

FIG. 2 shows a structure obtained by combining two structures 1 of the present invention shown in FIG.
FIG. 2 is a schematic cross-sectional view showing a use state of a roof plug structure having a shape bent at the center).
The outside air W blown into one (the left side in the figure) of the present invention structure 1 flows into the other (the right side in the figure) the present invention structure 1 after passing through the three small ventilation members 3. In addition,
In the connecting portion of the two structures 1 of the present invention, the lower flat plates 22 are separated from each other and communicate with the attic. The air in the attic is drawn into the structure 1 of the present invention in accordance with Bernoulli's law and discharged from the structure 1 of the present invention on the right side.

When a wind mixed with rain flows into the structure 1 of the present invention, when passing through the small ventilation member 3 and the rod-shaped space 5, the cross-sectional areas thereof are different. As soon as it comes out of the space 5, the flow velocity is reduced, and it hits the wall forming the ventilation hole 4 of the next small ventilation member 3. Has become.

FIG. 3 shows another example of the present invention, in which a net 6 is fitted into a rod-shaped space 5. The net 6 is made of a mesh having a roughness smaller than the diameter of the ventilation hole 4 and is fitted in a zigzag manner as shown in the figure.

[0019]

As described above in detail, the plug structure for an air-permeable layer opening according to the present invention comprises:
A plug structure comprising a ventilation member having a large number of communication holes, wherein the ventilation member aligns the communication direction of the ventilation holes,
In addition, the invention is characterized by being formed by a plurality of rows of small ventilation members intermittently spaced apart, and is an extremely advanced invention having various effects as described below.

Since the ventilation hole is not continuous from the inlet to the outlet and has a gap in the middle thereof, the blown rainwater or the like stops in the gap and does not reach the inside. Even if each ventilation hole is somewhat large, the high water stopping performance can be maintained, so that the entry of rainwater or the like can be prevented without impairing the ventilation performance. Since there is a gap in the middle, it is easy to reduce the weight.
