  However, when performing attic ventilation using the conventional ventilation gallery described above, it is necessary to install a plurality of ventilation louvers in the horizontal direction. In order to improve the ventilation performance, a larger number of ventilation louvers must be installed, which is not only uneconomical but also may impair the design appearance.

  Therefore, the present invention can be suitably used to perform attic ventilation, etc., has excellent workability, is economical, has high ventilation performance and water stopping performance, and has a good design appearance. It aims at providing the ventilation structure using the louver for ventilation.

  In order to achieve the above object, the ventilation gallery of the present invention is provided with a plurality of chevron blades spaced apart in the longitudinal direction between elongated plate-like members arranged substantially in parallel. It is characterized by that.

  Here, the long plate-like member is rectangular, and the frame may be configured by providing rectangular and short plate-like members at both ends of the rectangular long plate-like member.

  Further, the ventilation louver may be formed by connecting left and right end parts and at least one intermediate part in the longitudinal direction, and may be configured to a required length by the number of the intermediate parts to be connected. Good.

  The long plate-shaped member and the plurality of mountain-shaped slats are hollow structural materials in which a plurality of substantially parallel plate-shaped partition portions are provided approximately vertically at substantially equal intervals between substantially parallel plate materials. May be formed by overlapping and joining members cut out vertically to a required angle.

  Further, in the ventilation structure using the ventilation louver according to the present invention, the upper end portion of the draining sheet is attached in advance to one of the long plate-like members of any one of the ventilation louvers. A slit-like ventilation port is provided in the wall, and the other long plate-like member in which the ventilation louver remains is attached to the back of the wall above the ventilation port, and the lower end of the draining sheet is A rising ventilation path is formed by being fixed to the lower part of the ventilation opening.

  The ventilation gallery of the present invention configured in this way is a configuration in which a plurality of chevron-shaped wing plates are provided at intervals in the longitudinal direction between the elongated plate-like members arranged substantially in parallel. When performing attic ventilation, etc., it is not necessary to install many as in the prior art, so that it is excellent in workability and economical. In addition, since the ventilation path between the slats is a mountain shape, the air passing through the ventilation path with the folding between the slats will contact the surface of the slats evenly, so that the infiltration of rainwater is suppressed and high ventilation performance is achieved. The water stop performance can be improved while keeping it. Furthermore, since the vertical ventilation louver is provided with a plurality of chevron blades spaced apart in the longitudinal direction, the interval between the long plate-like members is reduced compared to the case of a horizontal ventilation louver. Compared to the case of a vertical ventilation louver using a single-flow vane, the width of the long plate-like member can be shortened and the interval is narrow. It can also be installed in a space. In addition, since it can be implemented in a thin and slim aspect, the slats appearing on the surface are not conspicuous and the design appearance is good.

  Here, the long plate-like members are rectangular, and when the frame is configured by providing rectangular and short plate-like members at both ends of the long and long plate-like members, both ends are reinforced. As a result, the strength of the ventilation louver can be increased.

  In addition, when the ventilation louver is configured by connecting the left and right end parts and at least one intermediate part in the longitudinal direction, and is configured to the required length by the number of intermediate parts to be connected, Depending on the needs of the building to be applied, the length of the ventilation louver may be changed according to the required ventilation performance, and the degree of freedom in design is high.

  Also, a long plate-like member and a plurality of chevron blades are required from a hollow structure material in which a plurality of substantially parallel plate-shaped partition portions are provided substantially vertically at substantially equal intervals between substantially parallel plate materials. When the members cut out symmetrically with respect to the angle are overlapped and joined to form, the ventilation louver can be easily manufactured because the processing is simple.

  Further, in the ventilation structure using the ventilation louver according to the present invention configured as described above, the upper end portion of the draining sheet is attached in advance to one of the long plate-like members of any one of the ventilation louvers. A slit-like ventilation port is provided on the wall of the building, and the other long plate-like member where the ventilation louver remains is attached to the back of the wall above the ventilation port, and the lower end of the draining sheet is Since it is fixed to the lower part of the ventilation opening and a rising ventilation path is formed, there is no worry of rainwater entering the building.
