Description

[Detailed Description of the Invention] The present invention relates to an in-wall ventilation structure using a frame wall construction method.

Framed wall construction methods, in which structural plywood, gypsum board, etc. are attached to a wall framework made of wood, and heat insulating materials such as glass wool are placed inside, are now widely used in residential construction, for example, as the two-by-four construction method. It is used for. This is because this construction method has great advantages such as economical efficiency and shortened construction period.

By the way, in the conventional frame wall construction method, in order to improve effects such as heat insulation and sound insulation, the wall is densely filled with heat insulating material. However, when the insulation material is densely packed into the wall, air cannot flow through the wall, so
When the temperature difference between the inside and outside of a structure becomes large, water vapor in the air condenses, which causes, for example, corrosion of the structure.

Therefore, the inventor of the present application proposed the following intra-wall ventilation method in order to prevent dew condensation within the wall and deal with corrosion of the structure. That is, as shown in FIGS. 1 and 2, in this method, an inner lining material 3 and an outer lining material 4 are attached to an upper frame 1 and a lower frame 2, and a heat insulating material 5 is placed inside the wall. An air flow path 6 is provided between the outer lining material 4 and the heat insulating material 5, and communication members 7 are provided at the upper and lower portions of the outer lining material 4 to communicate the air flow path 6 with the outside. The interior is naturally ventilated.

By the way, although the communication member 7 is suitable for air circulation, if left as it is, it will also allow foreign matter such as rainwater and pests to pass through, and if such foreign matter exists within the wall, it will cause rot and bad odors. Cause.

The present invention was developed in view of the above problems, and its purpose is to prevent foreign matter from entering the air flow path provided within the wall.

In order to achieve the above-mentioned purpose, the in-wall ventilation structure of the frame wall construction method according to the present invention includes a communication member that communicates the air flow path in the wall with the outside, and an outer member that hangs down from the opening of the cladding. It is characterized by being constructed by an inner member facing the outer member and means for preventing entry of foreign matter.

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

FIG. 3 is a cross-sectional explanatory diagram of main parts showing an example of the intra-wall ventilation structure of the frame wall construction method according to the present invention;
9 indicates an outer member of the communication member 7, 9 indicates an inner member, 10 indicates an intrusion prevention means, and other symbols are the same as in FIG. 2 and the like.

A heat insulating material 5 is disposed inside the wall formed by an inner lining material 3 such as structural plywood and an outer lining material 4 such as gypsum board attached to the upper frame 1 and the lower frame 2. ,
The heat insulating material 5 is not filled entirely inside the wall, but rather leaves an air passage 6 on the outer covering material 4 side. The air flow path 6 provided on the side closer to the outside A of the structure is connected to the outer covering material 4 provided at the upper and lower parts of the wall.
It communicates with the outside A via the opening portion 11 of and the communication member 7.

The communication member 7 consists of an outer member 8, an inner member 9, and an intrusion prevention means 10, and is a set of transverse members having bent heat insulation made of extruded aluminum or the like, for example. In order to prevent direct inflow of rainwater, the upper member 8 hangs down from above and faces the front of the outer covering material 4, and an intrusion prevention means 10 is installed in the hanging part.
It has a protrusion 12 for locking one end. The inner member 9 covered by the outer member 8 has an extending portion 13 extending in the horizontal direction for draining water, and also has an extension portion 13 for locking the other end of the intrusion prevention means 10 in correspondence with the outer member 8. It has a protrusion 14. Note that the outer member 8 and the inner member 9 have an arc-shaped connecting portion 15,
It has 16.

The intrusion prevention means 10 includes an outer member 8 and an inner member 9.
For example, it is made of a punched metal 17, which is a metal plate with countless pores. In addition, glass wool 1 attached with silicone to give water repellency or impregnated with insect repellent etc.
8 on the punched metal 17, the air flow path 6 in the wall can be communicated with the outside while further increasing the waterproofing and insect-proofing effects.

According to the above-mentioned in-wall ventilation structure according to the present invention,
An outer member hanging down over the opening of the air passage so as to cover the front surface of the opening, an inner member facing the outer member, and a foreign matter intrusion prevention means provided between the outer member and the inner member. By providing a communication member consisting of the above, it is possible to prevent rainwater and pests from entering the wall, and therefore it is possible to exhibit a significant effect of preventing corrosion of the structure.
