DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used as a heat insulating panel for an outer wall of a wooden house.

[0002]

2. Description of the Related Art In a wooden building such as a wooden house, especially in winter, indoor steam heated by the humidity difference between the inside and the outside of the house condenses on the inner surface of the outer wall, and the wooden building material is corroded. The service life will be shortened.

[0003] Therefore, at present, a wooden house is provided with a ventilation layer method to allow the outside air to flow through the ventilation layer on the inner surface of the outer wall, so that the steam generated in the building reaches the outer wall through the inner wall and is discharged together with the outer air flow. However, it is implemented to prevent dew condensation from occurring inside the outer wall.

FIGS. 9 and 10 are explanatory views of a conventional ventilation layer method. In a conventional ventilation layer method, a wooden base 71 is placed on a foundation 70 and a column 72 and a shaft member 73 are assembled. Then, an inner wall (not shown) using a heat insulating material is constructed, and windproof paper or a plate member 74 is stretched outside the inner wall.

[0005] Next, a ventilation layer body edge 75 is attached to the column 72 and the shaft member (stud) 72 'from the upper surface of the plate material or the windproof paper 74 by nailing, and a ventilation layer metal piece 76 is attached to the lower edge. 77 is stretched by the thickness of the rim 75 so as to form a ventilation layer between the plate member 74.

Accordingly, in winter, since the temperature of the air in the ventilation layer formed between the outer wall material 77 and the windproof paper (or plate) 74 is higher than the temperature of the outside air, it flows in from the ventilation layer metal. The outside air rises between the outside wall material 77 and the windproof paper 74 and is discharged to the outside of the cabin.

FIG. 10 shows the structure of the ventilation layer in the wall opening formed by the conventional ventilation layer method shown in FIG. 9 with the outer wall material 77 removed, and as can be seen from FIG. With respect to the opening O composed of the frame 78 and the vertical frame 79,
The rim 75 of the ventilation layer is attached to the horizontal frame 78 with an interval S therebetween.

[0008] Therefore, in the lower part of the opening O, arrow A ₂₀ via the ascending air flow A ₂ is the interval S between the cylinder edge of the vent layer laterally
At the upper part of the opening O, the air flow in the ventilation layer is increased by the arrow A ₂₀ via the space S between the body edge 75 and the horizontal frame 78.
Flows from the side as shown in FIG.

[0009]

In the conventional ventilation layer method for the outer wall, it is necessary to heat-insulate at the site and then to perform an additional method. The heat insulation method and the ventilation layer method are sequentially performed in two stages. Doing so requires a lot of labor and construction costs are high.

[0010] In the case of a ventilation layer construction method on site, the construction of the rim for the ventilation layer is complicated, and the surroundings of the opening (window) O as shown in FIG. Wrong or inadequate construction accuracy does not achieve sufficient ventilation, and the building does not have the useful life as designed.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned defects, and to achieve the elimination of the complexity of on-site construction by using a panel which has both a heat-insulating material and a ventilation layer produced in a factory. Things.

[0012]

As shown in FIGS. 1 and 2, for example, as shown in FIGS. 1 and 2, an upper surface formed by a vertical frame member 1, 1 'and a horizontal frame member 2 has a rectangular shape. A surface material 3 having a surface slightly wider than the body is stretched, and a heat insulating material 6 is formed in a space formed by the frame and the surface material between the surface material and the heat insulating material upper surface. 31 groups of grooves formed on the inner surface of the face material
Air passages such as notches 32 extending from the edge of the face material to the inside of the frame
To form a heat insulating panel with a ventilation layer in which the air of the ventilation layer G in the frame is communicated outside beyond the frame.

Therefore, the heat insulating panel with the ventilation layer of the present invention is used as a wooden building material, and the portion protruding from the frame of the face material is nailed to the frame of the pillar or base and used for the outer wall construction. An outer wall equivalent to a wall subjected to layer construction can be formed easily and accurately. Moreover, the ventilation path is
It is formed only on the face material so that it communicates outward beyond the body
Causes a decrease in the strength of the frame as a structural material of the panel
Can be formed reasonably without any problems. Also, since the upper surface of the frame is flush, the joining of the face material 3 to the frame is performed by the vertical frame materials 1 and 1 '.
In addition, the entire upper surface of the horizontal frame member 2 can be joined and firmly implemented, and the space maintaining member 4 can be easily attached. In addition, between the face material 3 and the frame, from the frame inside the frame
Since the air passage 31 which communicates with the outside is present, panel
The outer material such as a plate material or a sheet material is stretched on the
However, in the panel, the ventilation of the ventilation layer G inside the frame body to the outside of the frame body can be suitably and sufficiently achieved without hindering the ventilation function .

The gas permeable layer G is made of a material having a small moisture permeability resistance.
And a space maintaining material 4 comprising a mounting portion 41 around the periphery
Is formed by being interposed between the heat insulating material 6 and the inner surface of the face material 3, so that the space is maintained not only for the filling of the glass wool heat insulating material but also for the injection of the foamed resin. Moisture that is transmitted through and propagates through the space maintaining material and is appropriately discharged to the outside by the airflow of the ventilation layer G communicating with the outside of the frame , so that dew condensation on the inner surface of the face material 3 can be prevented.

Further, as an air passage between the inside of the frame and the outside of the frame,
Since the oblique grooves 31 are formed on the inner surface of the face material, the opening O over the entire width of the panel is partitioned by the horizontal frame 8 and the vertical frame 9 at the center of the panel as shown in FIG. Even when the panel central portion is partitioned by the frame, the outside air can flow through the grooves 31 opened to the side of the panel as shown by arrows A ₁ (inflow) and A ₃ (outflow) to the ventilation layer G in the panel. Guaranteed.

【Example】

[Example 1 (FIG. 1, FIG. 2, FIG. 3, FIG. 4)] The vertical frame members 1, 1 on both sides and the intermediate vertical frame member 1 'are fixed to the upper and lower horizontal frame members 2, 2, and the width is reduced. A rectangular wooden frame having a length between the pillars, a length between the base and the upper horizontal shaft member, and a flush upper surface was prepared. Next, as shown in FIG. 3, a space-retaining material is formed by molding a paper material having a small moisture-permeation resistance into a shape having a pyramid-like projection of substantially pyramid on the entire surface and having a flat mounting portion 41 on four sides. 2 and 3, as shown in FIG. 2 and FIG.
Placed on top.

Next, a group of grooves 31 obliquely parallel to one surface is cut and formed in the face plate 3 of the structural plywood having a surface slightly wider than the frame body and having high moisture permeability, and the grooves 31 are formed on the inner surface. The face material 3 is placed on the frame so that the frame materials 1, 1 ', 2, the mounting portion 41 of the space maintaining material 4, and the face material 3 are nailed.
The frame, face material and space maintaining material were integrated.

Next, the integrated frame is placed on a platen of a conventional press table such that the face material 3 faces down, and the open surface of the frame is placed on the press table upper plate via a release paper 5. And the foamable urethane resin was injection-molded through the injection hole 21 of the frame material.

The resulting panel has a solid structure with the upper surface flush.
Since the face material having a surface that is slightly wider than the frame body is fixed to the frame body, the frame body is fitted between the pillars of the building so that the face material 3 is on the outside air side, the flat portion out of the four sides of the frame body was nailed to the framework of the columns and foundation sequentially wall surface can be formed, the only face material in the framework of the pillars and the foundation just nailing
Thus, a heat-insulating outer wall with a ventilation layer having a simple appearance in which the structural frame reinforces the framework could be easily formed. Moreover, the traffic within the frame
A ventilation path for communicating the gas layer G with the outside of the frame is formed on the inner surface of the face material by the groove 3.
Open it from the inside of the frame over the frame at a depth of 1
In use, an exterior material such as a plate material is placed on the upper surface of the face material 3 during use.
The air permeability of the panel itself can be maintained even when the panels are used in layers.

In a house in which the panel of this embodiment is stretched as an outer wall, the peripheral edge of the face material 3 is fixed to the shaft material or the pillar surface.
Irrespective of the configuration, the groove 31 on the inner surface of the face material 3 forms a ventilation path at the interface with the base surface, the shaft material, and the column surface, and the inside of the heating room has a considerable temperature with the outside. Due to the difference, the air A ₁ flowing from the groove 31 at the edge of the face material 3
Is in the panel increases the ventilation layer G as a free upward flow A _2, the face plate 3 above the outlet air A ₃ becomes from the grooves 31, the panel outside air was bubbled.

Therefore, even when the room is heated in winter when the temperature difference between the room and the outside is large, the room humidity rises, and even if the temperature and humidity propagate through the heat insulating material and permeate the space maintaining material, the ventilation layer G Since the outside air is circulated, no condensation was formed on the inner surface, that is, the inner surface of the outer wall, though the face material 3 had high moisture permeability resistance.

FIG. 4 shows a case in which an opening (window) O extending over the entire width of the panel is provided in the middle of the panel of this embodiment. As is clear from FIG. 4, a horizontal frame 8 of the opening partitions the middle of the panel. In other words, even when the horizontal frame 8 closes the groove 31 of the face plate 3 of the panel, an arrow A is formed through the lower edge and the right and left edge grooves 31.
₁ as the outside air flows into the panel, will free flow in the panel as indicated by the arrow A _2, and discharged as indicated by the arrow A _3.

Further, since the space maintaining material 4 has a small moisture permeation resistance, it efficiently discharges the humidity transmitted through the heat insulating layer, and forms a ventilation layer G communicating with the whole inside of the panel by scattered pyramid-like projections. and for which the air flow a ₂ in the panel was effectively flows in the free direction.

Example 2 (FIGS. 5, 6, 7, and 8) Only the face material was changed from Example 1, and the other steps were the same.
That is, the surface material 3 in contact respectively to the upper and lower ends equivalents
Notch 32 for communicating the inside and outside of the horizontal frame member 2
And, similarly to the first embodiment, the vertical frame members 1 and 1 ′ and the horizontal frame member 2
A frame body having the same upper surface , a space maintaining material 4, and a surface material 3
And nailing, foam insulation (hard urethane resin)
Was formed and filled into the inner surface of the space maintaining material 4.

As shown in FIG.
The outside wall of a wooden house was formed by nailing between pillars with the outside air side. The outside air flows into the ventilation layer G inside the panel from the notch 32 at the lower edge as shown by an arrow A ₁ , rises as free flow as shown by an arrow A ₂ inside the panel, and is discharged from the notch 32 at the upper edge. Then, it flowed into the upper panel 3 from the notch 32 on the lower edge thereof (arrow A ₃ ).

In the case of the panel of this embodiment, when an opening extending over the entire width is provided in the middle and the horizontal frame 8 (FIG. 4) partitions the middle of the panel, the edge of the panel abutting on the horizontal frame 8 is also cut. Chip 3
2, the intended object of the present invention was achieved as in Example 1.

[0027]

As described above, in the air passage forming means for forming the oblique grooves 31 in the face material of the first embodiment, the processing accuracy is required, but the air can be dispersed widely.
When the opening O is provided in the middle portion of the panel, no special ventilation path needs to be formed. Naturally, when the groove 31 group is provided in the vertical direction and the opening O is formed in the middle of the panel, the horizontal frame 8
A notch 32 is required at the edge that abuts (FIG. 4).

The air passage forming means of the second embodiment is easy to process, but has a notch at the edge of the face material 3.
To order, Yosu attention a partial decrease in strength in handling-out invited
However, there is no notch in the frame itself.
After fitting the panel between the frame members,
As in the case of the panel of Example 1, the frame functions as a reinforcing structural material
In addition, the panel itself suitably develops heat insulation and air permeability.
Conduct. In addition, the notch 32 as an air passage is formed on the upper surface of the frame material.
The distance between the surface and the top of the face
Is open to the edge of the face material beyond the upper surface of the frame.
Notch 32 is ventilated even if plate or sheet material is stretched on top
It acts as a road.

As a heat insulating material, glass wool or the like can be used.
Other conventional materials can be used. Further, the space maintaining material only needs to have a low moisture permeability resistance and a shape retaining property against the pressure of the heat insulating material. For example, a corrugated molded paper or a molded nonwoven fabric may be used.

When a glass wool layer whose surface has been formed or a foamed material whose surface has been formed into a corrugated shape or the like is formed as a heat insulating material, the shape preserving surface of the heat insulating material may be reduced. Since the space is maintained in contact with the face material, the space maintaining material is unnecessary.

The dimensions and shape of the frame and the application of the vertical and horizontal intermediate members are also freely selectable within the scope of the present invention, and can be formed into an appropriate shape in accordance with the 2 × 4 construction method of the Building Standard Law. When the horizontal intermediate material is put into the material to be injection-molded by foaming, it is convenient to make the horizontal intermediate material surface lower than the surrounding frame material surface, for example, so that the horizontal intermediate material does not block the flow of the injection foaming liquid.
Furthermore, if the upper and lower surfaces of the frame are flush,
Filling work on a press table is easy.

[0033]

According to the present invention, the panel itself is a frame having a flush upper surface.
Form in which a face material having a surface slightly wider than the frame is stretched on the body
Since it is equipped with a heat insulating material and a ventilation layer at the site, simply fitting the panel frame between the shafts and fixing it with the
Regardless of the form that is installed smoothly, the outer wall equivalent to the one that has been subjected to heat insulation construction and ventilation construction is once and easily,
Moreover, it can be performed accurately, and it is possible to reduce labor on site and shorten the construction period, thereby reducing the construction cost.

Further, since the upper surface of the frame is flush, the bonding of the surface material 3 to the frame is firmly performed by bonding to the entire upper surfaces of the vertical frame materials 1 and 1 'and the horizontal frame material 2. It is possible to easily attach the space maintaining material 4. Moreover, only the face material 3 has a frame
Damage to the frame as a panel structural material due to the presence of the ventilation passage in a form that communicates from inside the body over the frame to the outside
Air flow to the frame outside the no frame body ventilation layer G is sufficiently be achieved, even when stretched the exterior material of the plate or the like on the panel surface, the frame body
Ventilation from outside to the frame can be sufficiently achieved.

When used in a 2 × 4 construction house, the structural plywood stretched on the outer wall surface has a high moisture permeability resistance, but even if glass wool is used as a heat insulating material, the plywood is connected to the outside of the panel frame.
The presence of the ventilation layer G does not cause internal dew condensation inside the wall, and eventually lowers the heat insulation performance of the building,
It does not adversely affect the durability of the building.
