The present invention includes an invention relating to a ventilation panel and an invention relating to an outer wall structure using the ventilation panel. Therefore, the ventilation panel will be described first, and then the outer wall structure will be described.

FIG. 1 shows an example of a ventilation panel according to a first embodiment of the present invention. The ventilation panel shown in FIG. 1 includes, for example, a plate material 11 and a convex portion 12 provided on the plate material.

The plate 11 is made of, for example, resin, metal or the like. Specifically, an ABS resin, a polypropylene resin, or the like can be used. The thickness of the plate 11 is
It can be thin if strength allows. For example, it can be 1 mm or less, more specifically, about 1 mm to 0.7 mm. Further, in the present embodiment, the convex portion 12 is formed integrally with the plate member 11 as shown in FIG. That is,
Structurally, a part of the plate member 11 is formed so as to protrude toward one surface side. Therefore, the convex portion 12 is formed on one surface side of the plate member 11, and the corresponding concave portion 13 is formed on the opposite surface. As described above, since the plate material 11 and the convex portion 12 are integrated, the structure is simple, the handling is easy, and the plate material 11 and the convex portion 12 can be integrally formed of the same material.
It can be easily manufactured as a building plate. Moreover, since it is lightweight, conveyance is easy and handling is easy at a construction site. Of course, the load on the building frame is small.

In the present embodiment, the convex portion 12 is formed in a square shape in both a cross section parallel to the surface of the plate member 11 and a cross section perpendicular to the cross section. One side of the rectangular outer shape may be, for example, about 12 mm. The protruding height can be, for example, about 5 mm. And it is formed in a matrix with a plurality of rows and a plurality of columns. With such a distribution of the protrusions 12, a space is secured between the protrusions 12. Moreover, this space
They are in communication with each other. Therefore, when this ventilation panel is attached to an object to be attached, each projection 1
The space between the two forms a ventilation layer.

Next, a second embodiment shown in FIG. 2 will be described. The ventilation panel shown in FIG. 2 has a plurality of protrusions 12 arranged in a matrix on one surface of a plate material 11, similarly to the panel shown in FIG. Also in this example, the convex portion 1
2 is formed integrally with the plate material 11.

In the present embodiment, the projections 12 are
The cross section parallel to is circular, and the cross section perpendicular to it is formed in a shape in which the top of a semicircle is cut flat.
The protrusion 12 is formed, for example, to have an outer diameter of about 12 mm and a protrusion height of about 5 mm. Also in this case, similarly to the first embodiment, the space between the projections 12 forms a ventilation layer.

Next, a third embodiment shown in FIG. 3 will be described. The ventilation panel shown in FIG. 3 has a rectangular projection 12 having the same shape as that of the panel shown in FIG. Other structures are the same as the example of FIG.

The projections 12 are not limited to one side of the plate material 11 and may be formed on both sides. Also, the convex portion 1
The distribution of 2 is not limited to the matrix and the houndstooth check, but may be another distribution mode.

Further, the plate material 11 can be formed into a standard shape for architectural use, and cut and used as needed. By doing so, the cost can be further reduced.

Next, a first embodiment relating to an outer wall structure of a building formed using the above-described ventilation panel will be described with reference to FIGS. 4 and 5. FIG.

FIG. 4 shows a part of a wall structure of a wooden house as a building. In FIG. 5,
It shows a partial cross-sectional structure of a wall surface of a building.

In FIG. 4, after a structural plywood 23 is attached to pillars 21 and studs 22 of a building with nails or the like, a moisture-proof sheet 24 is adhered thereon. It is stacked with the lath 30 in a direction protruding toward the inside of the object. Then, for example, the screw 30 and the ventilation panel 10 are driven into the pillar 21, the stud 22, and the like via the lath 30 and the ventilation panel 10, so that the lath 30 and the ventilation panel 10 are fixed to the building body of the building. At this time, a process of winding the insect repelling tape 32 is performed on the lower end sides of the ventilation panel 10 and the lath 30. A drainer 33 is provided on the lower end sides of the ventilation panel 10 and the lath 30.

In this state, mortar 40
Is painted. The mortar 40 reaches the recess 13 of the ventilation panel 10 through the mesh of the lath 30 (see FIG. 5). Thus, an outer wall structure is formed.

In this example, the lath 30 and the mortar 4
Although the outer material is constituted by 0, the present invention is not limited to this. For example, a siding board or the like may be used as the exterior material.

In this example, a heat insulating material is not shown, but, for example, it is loaded between the pillar 21 and the stud 22. Further, instead of or together with the structural plywood 23, a heat insulating material may be attached to the outer surfaces of the columns 21 and the studs 22. Further, the heat insulating material is applied to the pillar 21 and the stud
2 may be provided only on the outer surface. Glass wool, styrene foam, or the like can be used as the heat insulating material.

In this manner, as shown in FIG. 5, the mortar of the exterior material is applied to the outside of the structural plywood 23 with the ventilation panel 10 interposed therebetween. that time,
Each of the convex portions 12 of the ventilation panel 10 is made up of the plate material 11 and the
3, and as a spacer, a space is secured between each of the plurality of convex portions 12 distributed. The space between each convex part 12 is
Since the ventilation panel 10 has the structure shown in FIG. 1 and communicates with each other, this space functions as the ventilation layer 14.

Therefore, according to the present embodiment, there is an effect that a ventilation layer can be secured by arranging a ventilation panel having a simple structure and easy to handle inside the exterior material.

In the above-described example, the ventilation panel 10 and the lath 30 are overlapped and attached at the construction site, but the present invention is not limited to this, including other examples described below. The ventilation panel and the lath may be produced in a state of being connected in advance. For example, a metal ventilation panel and a lath are joined and connected by welding or the like, a lath is bonded to a resin ventilation panel with an adhesive, and the ventilation panel and the lath are connected using a connector. The connection can be made in various modes such as connection.

Next, a second embodiment of the outer wall structure of the present invention will be described with reference to FIG.

FIG. 6 shows an example in which a heat insulating treatment is performed on the outer wall of the foundation. In the example of FIG. 6, a heat insulating material is provided on the outside of the foundation to improve heat insulation at the foundation. Such insulation is typically provided at ground level (ground) GL.
Attached to its outside along a foundation 50 which continues from the bottom to the bottom.

In the outer wall structure shown in FIG. 6, a heat insulating material 60 is attached to the outside of the foundation 50, and the outside ground portion (GL)
On the upper side), the ventilation panel 10 and the lath 31 are fixed with nails or the like, and the mortar 40 is painted from outside thereof. In addition, the heat insulating material 60 and the ventilation panel 10
For example, it can be fixed to a foundation with an anchor bolt or the like.

With such a configuration, on the surface of the heat insulating material 60, the convex portion 12 of the ventilation panel 10 functions as a spacer between the plate material 11 and the heat insulating material 60, as shown in FIG. Space is secured between the parts 12. And
Since these spaces communicate with each other, the ventilation layer 14
Is formed.

In this example, the heat insulating material 60 is not covered with the ventilation panel 10 below GL. This is because the heat insulating material 60 is under the ground and is not directly exposed to rain.
However, in consideration of the penetration of moisture in the ground, it is preferable to use a heat insulating material having as little hygroscopicity as possible, for example, styrene foam.

FIG. 7 shows a third embodiment of the outer wall structure. The present embodiment is an example in which the heat insulating material 60 is covered with the ventilation panel 10 below GL, that is, even in the ground.

In the outer wall structure shown in FIG. 7, a heat insulating material 60 is attached to the outside of the foundation 50, and the outside ground portion (GL)
From above (from above) to the underground portion (below GL), it is covered with the ventilation panel 10, and the above-ground portion is further covered with a lath, and the mortar 40 is painted from the outside thereof. Further, the heat insulating material 60 and the lower end of the ventilation panel 10 are waterproofed by the seal material 70. The heat insulating material 60 and the ventilation panel 10 can be fixed to the foundation 50 with, for example, anchor bolts or the like.

With such a configuration, the surface of the heat insulating material 60 is covered with the ventilation panel 10 from the upper end to the lower end. In this state, the projection 12 of the ventilation panel functions as a spacer between the plate 11 and the heat insulating material 60. As a result, a space is secured between the respective convex portions 12. Since these spaces communicate with each other, the ventilation layer 14 is formed. For this reason, water vapor evaporating from the foundation can be released upward through the ventilation layer 14.

According to the present embodiment, since the heat insulating material 60 is covered by the ventilation panel 10, it does not receive the penetration of moisture in the ground. Therefore, even a heat insulating material having a strong hygroscopic property can be used without getting wet. Specifically, it becomes possible to use glass wool having excellent heat insulation performance.

In the examples shown in FIGS. 4, 5 and 6,
Although the example using the ventilation panel shown in FIG. 1 is shown, the present invention is not limited to this. A ventilation panel of another form, for example, a ventilation panel having a structure shown in FIGS. 2 and 3 can be used.

As described above, according to the embodiment of the present invention, it is possible to easily and securely secure the ventilation layer inside the exterior material.
It can be done reliably. For this reason, in a highly airtight house, water vapor can be released by the ventilation layer inside the exterior material, and decay of wood due to condensation or the like can be prevented.

The ventilation panel according to the present embodiment can be easily formed by, for example, integrally molding a resin material, and can be manufactured at a low cost. Moreover, since it is thin and light, there is an effect that handling in operations such as transportation and mounting is easy. As a result, the ventilation panel can be easily mounted, and the construction period can be shortened as compared with the case where the spacers are individually mounted.

[0047]

According to the present invention, it is possible to provide a ventilation panel which can secure ventilation with a simple structure, can be easily mounted, and can be manufactured at low cost.

Further, according to the present invention, when forming the outer wall structure, it can be easily constructed with a simple structure, and the construction period can be shortened.
