Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a framed wall structure including a ventilation passage in a wall and a house made of the framed wall structure.

[0002]

2. Description of the Related Art In recent years, a house with a framed wall structure has attracted attention due to the trend of Western-style architecture and the demand for a high level of earthquake resistance. This is the vertical frame 2, horizontal frame 3, and bearing surface material 9 shown in FIG.
The wall panel 10 in which the floor joists 4 are combined with each other, or the floor panel 11 in which the floor joists 4 and the load bearing surface materials 9 are combined are tightly connected to each other, thereby exhibiting structural strength.
It has a feature that it can easily obtain a higher structural strength than a wooden frame structure that tightly connects the beams 17, the base 18, the girders 19 and the braces (not shown). Moreover, since the outdoor side of the wall panel 10 shown in FIG. 4 is covered with the load bearing surface material 9 and the indoor side is covered with the interior base material 12 such as gypsum board, the airtight performance required from the viewpoint of energy saving is also high. It's also easy to get. On the other hand, the fact that the inner and outer surfaces of the wall panel 10 shown in FIG. 4 are covered with the bearing surface material 9 and the like means that the air in the wall panel 10 is sealed and immovable, which makes it possible to move in the summer. This air acts as a heat storage unit, and radiant heat from this air may cause an extremely unpleasant living environment in which "it is hot even if the room temperature is adjusted". Regarding the reduction of the radiant heat, the air in the wall panel 10 shown in FIG. 4 can be moved by connecting the underfloor space 14, the intra-wall space 13 and the attic space 15 as shown in FIG. However, it is difficult to provide a ventilation path as shown in FIG. 5 while maintaining the structural strength of the framework wall structure itself. for that reason,
As disclosed in Japanese Unexamined Patent Publication No. 07-42254, a ventilation path is separately provided on the outdoor side of the load bearing surface member 9 shown in FIG. 7, and as shown in Japanese Unexamined Patent Publication No. 09-125544, the upper and lower portions shown in FIG. There has been proposed a construction method in which the gap provided by making the short side of the horizontal frame 3 shorter than the short side of the vertical frame 2 is regarded as a ventilation path. However, in the method of separately providing the ventilation path on the outdoor side of the load bearing surface material 9 shown in FIG. 7, the outer wall has an excessive thickness, which causes a problem in terms of design. Further, it has been pointed out that the exterior material 24 must be supported after securing a ventilation path and the risk of the exterior material 24 falling down. Further, the method of making the short sides of the upper and lower horizontal frames 3 shorter than the short sides of the vertical frames 2 shown in FIG. 8 cannot secure the strength of the framed wall structure itself, and structural danger is pointed out. It had been. Therefore, conventionally, as shown in FIG. 5, the vertical frame 3 has to be secured in the wall panel 10 by providing the horizontal frame 3 and the head joint 1 with a slight vent hole 20 that does not affect the structure. .

[0003]

However, since the ventilation passage inside the wall that is secured only by providing the small ventilation holes 20 in the horizontal frame 3 and the head joint 1 shown in FIG. 5 is limited to the vertical direction, the structure is structurally improved. From the standpoint of 2 ventilation holes on each wall panel
If 0 could not be provided, there was a risk that air that could not be moved would still be present and that a sufficient ventilation passage inside the wall could not be secured. In addition, even if a ventilation hole is provided in the lintel or window sill at the opening, the window frame may block the ventilation hole 20 and an effective ventilation path may not be secured. The present invention has been made in order to solve the above-mentioned conventional drawbacks, and an object of the present invention is to form an immovable air in a framed wall structure and a house made of the same while maintaining essentially high structural strength. It is an object of the present invention to provide a framed wall structure capable of securing an in-wall ventilation path capable of suppressing radiant heat in the summer and a house made of the framed wall structure.

[0004]

In order to achieve the above object, a first aspect of the present invention is to provide a ventilation hole provided in a vertical frame which constitutes a wall body and a ventilation hole provided in a lateral frame which constitutes the wall body. And a framed wall structure including a vent provided in a head joint that tightly connects the walls and a vent provided in a load bearing surface material that constitutes the floor, and these vents serve as an underfloor space and The present invention relates to a framed wall structure including an in-wall ventilation path that enables communication between an in-wall space and an attic space. According to a second aspect of the present invention, there is provided a ventilation hole provided in a vertical frame forming the wall body, a ventilation hole provided in a horizontal frame forming the wall body, and a ventilation hole provided in a head joint for tightly connecting the wall body, A framed wall structure having ventilation holes provided in a load-bearing surface material that constitutes a floor body, wherein the ventilation holes in the wall allow communication between the underfloor space, the space inside the wall, and the attic space. The present invention relates to a house having a framed wall structure including. According to a third aspect of the present invention, there is provided a ventilation hole provided in a vertical frame forming the wall body, a ventilation hole provided in a horizontal frame forming the wall body, and a ventilation hole provided in a head joint for tightly connecting the wall body. A framed wall structure having ventilation holes provided in a load-bearing surface material that constitutes a floor body, wherein the ventilation holes in the wall allow communication between the underfloor space, the space inside the wall, and the attic space. The present invention relates to a house having a framed wall structure including an openable and closable damper that communicates the outside air with the ventilation path inside the wall. Here, the ventilation hole means a hole provided in the vertical frame 2 or the horizontal frame 3 constituting the wall panel 10 shown in FIG. The space inside the wall refers to the space 13 inside the wall panel 10 shown in FIG. 1 or the space between the exterior material and the interior material in the wall portion shown in FIG. 6, and the ventilation passage inside the wall is shown in FIG. A path that connects the underfloor space 14, the in-wall space 13 and the attic space 15 to each other.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a framed wall structure according to the present invention, in which a vent hole 20 provided in a vertical frame 2 that constitutes a wall panel 10 and a vent hole 20 provided in a lateral frame 3 that constitutes the wall panel 10, 1 shows a framed wall structure including a vent hole 20 provided in a head joint 1 for tightly connecting a wall panel 10 and a vent hole 20 provided in a load bearing surface material 9 constituting a floor panel 11. Here, the ventilation holes 20 of the vertical frame 2 and the ventilation holes 20 of the horizontal frame 3
By combining and
When it is not possible to provide the air passage, the immovable air, which is still kept around the opening, can be moved horizontally through the ventilation hole 20 to ensure a sufficient intra-wall ventilation path. Therefore, the conventional problems can be solved. Here, the vent hole 20 may be provided by either on-site processing or factory processing, but as shown in FIG. 3, the lateral frame 3, the head joint 1 or the load bearing surface material 9 is previously prepared.
From the viewpoint of work efficiency, it is preferable to provide the ventilation hole 20 by factory processing. It should be noted that the vertical frame 2, the horizontal frame 3, the head joint 1 or the material of the load bearing surface material 9 and the size and shape of the vent hole 20 can be arbitrarily selected by checking the structural calculation. For example, the material may be solid wood such as cedar, pine, rice bran, etc. or structural laminated wood, and the size and shape of the ventilation hole 20 may be slit-like in the range of 100 mm × 8 mm to 200 mm × 25 mm, inner diameter. A hole having a diameter of 12 mm to 36 mm can be exemplified. Further, the vent hole 20 is not only provided in the center of the horizontal frame 3 or the like,
It may be provided in the end portion to form a comb-shaped hole. Further, as shown in FIG. 1, when a damper 26 that can be opened and closed is provided to communicate the ventilation path inside the wall with the outside air, further reduction of radiant heat can be expected by introducing cold air at night in summer. The damper 26 that can be opened and closed here is one that can connect the ventilation path inside the wall to the outside air, and is provided on any of the roof surface, the wall surface, and the outer peripheral surface of the foundation. For normal openings such as drake windows and skylights. It is a concept that includes joinery. Although the damper 26 is installed on the outer peripheral surface of the foundation in FIG. 1, it may be installed on the roof surface, the wall surface, or in a plurality of portions. Further, as shown in FIG. 1, when performing heat insulation work, polystyrene or polyurethane is used rather than the filling heat insulation method in which the wall panel 10 is filled with a fiber heat insulating material such as glass wool, rock wool, or cellulose fiber from the viewpoint of securing a ventilation path in the wall. It is preferable to use a foamed plastic heat insulating material external insulation method in which a resin such as polyethylene is foamed at a predetermined ratio with a foaming component. As the heat insulating material to be used, one having polystyrene as a main material is more preferable from the viewpoint of heat insulating performance and safety at the time of combustion. Such heat insulation work is preferable from the viewpoint that the bearing surface material is on the indoor side and the occurrence of dew condensation is suppressed. FIG. 2 is a perspective view of the framework wall structure according to the present invention. As a result, the window frame does not have a shape of pressing the lintel or the ventilation hole of the window sill around the opening, and a sufficient ventilation passage inside the wall can be secured, and the conventional problems can be solved. Further, the present invention can be applied to a framed wall structure and a house formed of the framed wall structure, for example, a so-called steel house in which a part of the structure is replaced with a lightweight steel.
