Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a ventilation structure near an upper part of an outer wall of a building.

[0002]

[Prior Art]

 Ventilation near the upper part of the outer wall of the building, for example, near the lower surface of the ceiling, is natural ventilation, and ventilation paths with the required cross-sectional area are provided with appropriate distribution, and the ends of the ventilation paths are covered with a grid on both the indoor and outdoor sides. Many have different structures.

[0003]

[Problems to be solved by the device]

 However, the conventional ventilation structure has problems that its construction is complicated and that its appearance is easily damaged. In other words, if the ventilation volume is to be made sufficient, the ventilation area will naturally increase, but there are many problems with the distribution and structure when distributed in a distributed manner. If each dispersed route is made large and the number is small, the size of the route tends to affect the member composition in the vicinity, making it difficult to keep the rain off the edge on the outdoor side. If it is made into individual pieces, the construction is troublesome, and the appearance of the outdoor end is often impaired. It is an object of the present invention to provide a ventilation structure that is easy to construct even if the ventilation path cross-sectional area is large, has a small effect on the nearby member structure, and does not impair the appearance.

[0004]

[Means for Solving the Problems]

 The ventilation structure according to the present invention is a ventilation structure in which a breathable rod member is arranged in a ventilation path of an upper edge of a building outer wall, and the breathable rod member is an elongated flat sheet with respect to a width of the flat sheet. A multi-layer sheet body to which corrugated sheets forming parallel holes along the direction are attached is bent at a substantially right angle along the longitudinal direction at the widthwise middle portion, and the folded multi-layer sheet body is laminated. It is formed by forming a rod-shaped body having a bent portion with a substantially L-shaped cross section.

[0005]

[Action]

 The air-permeable rod member has a plurality of fine holes arranged in parallel in a direction orthogonal to the longitudinal direction, is bent at an intermediate angle at a substantially right angle, and is further laminated to form a ventilation path in which each fine hole is finely divided. The presence of the corrugated sheet and the flat sheet for partitioning each of the small holes has a shape similar to a so-called honeycomb structure, and this breathable rod member also acts as a structural member having high strength and rigidity. Further, each end of the corrugated sheet and the flat sheet also serves as a screen for the end of the ventilation path of the breathable member.

【Example】

 FIG. 1 is an exploded perspective view showing an embodiment of the ventilation structure of the present invention, and FIG. 2 is a vertical sectional view of an outer wall portion to which the ventilation structure of FIG. 1 is applied. In the figure, 1 is a ventilation structure, 2 is a breathable rod member, 3 is an outer wall, 4 is a ventilation path, 5 is a reinforcing L-shaped member, 21 is a flat sheet of the breathable rod member 2, 22 is also a small hole, 23 Is a corrugated sheet and 24 is a multilayer sheet body. As shown in FIG. 1, in the ventilation structure 1 according to the present embodiment, a breathable rod member 2 is arranged in a ventilation path 4 on a side of an upper edge portion of an outer wall 3 of a building as a part of the ventilation path 4. The breathable rod member 2 is formed by adhering a corrugated sheet 23 forming narrow holes 22 arranged in parallel along the width direction to a long and thin flat sheet 21 to form a multilayer sheet body 24, which is formed in the width direction. Bending at a substantially right angle along the length direction at the intermediate portion, a plurality of sheets of this form are laminated and obtained. As a result of the stacking, since the narrow hole 22 is bent at a right angle in the middle, a rod-shaped body having a bent portion with a substantially L-shaped cross section is formed, and this is the breathable rod member 2. In this case, the multi-layer sheet body 24 is similar to a generally used water-resistant corrugated board box made up of a corrugated sheet made of plastic and a flat sheet, and the diameter of the narrow holes 22 is about the same. The multi-layer sheet body 24 having a thickness of 3 mm is adhered and laminated so as to have a required thickness.

In this embodiment, an L-shaped reinforcing L-shaped member 5 having an L-shape is adhered to the protruding corner side of the breathable rod member 2. This is because the breathable rod member 2 alone tends to be easily damaged or broken during transportation or on-site placement. However, this tendency is improved. This is because the material 5 is used as a part of the structural material to facilitate the construction. The breathable rod member 2 configured as described above is prepared as a long material, cut as necessary, and placed near the upper portion of the outer wall 3 as shown in FIG. In this case, between the upper end surface of the outer wall 3 using a hollow wall panel and the girder material 31, there is a ventilation path 4 toward the room, and the air permeable rod member 2 becomes a part thereof. Then, on the outer side surface of the outer wall 3, the bent corner of the breathable rod member 2 is placed on the lateral member 32 which is previously attached to the outer surface upper edge of the outer wall 3, and the breathable rod member 2 is attached to the ventilation path 4. It is placed so that one end facing vertically is in contact.

The other lateral end of the breathable rod member 2 faces the outside, and this is the end of the ventilation passage 4 on the outdoor side, above the lateral member protruding laterally of the beam member 31. The metal plate constructed from above is wound around the lower end of the reinforcing L-shaped member 5 for rain protection. Therefore, one side edge of the reinforcing L-shaped member 5 is slightly projected in advance as shown in the figure. A lattice frame 33 is attached to the indoor end of the ventilation path 4 that goes into the room, but the edge is shown as a form in which the rims of the ceiling are doubled with a gap. Instead, it may be breathable.

The ventilation structure 1 according to the present embodiment can be constructed and arranged as described above, and thus can be extremely easily installed. That is, the breathable rod member 2 has a flat sheet 21 and a corrugated sheet 23 around a large number of small holes 22 therein, and is similar to a honeycomb structure, and is a high-strength and high-rigidity material. The shape is simple, it can be used as a structural material to some extent, it can be easily arranged with little effort, and there is little influence on the structure of nearby parts. And since it is a small hole 22 with a wall that is partitioned by each of the above-mentioned sheets, its end portion has a screen form and has a simple appearance, and it is not necessary to arrange a lattice frame or the like. Therefore, the appearance is not spoiled. Further, the breathable rod member 2 can freely prepare a cross-sectional area and a length, and can cope with a wide range of ventilation capacity, and the ease of construction does not change even if the cross-sectional area as a ventilation path is increased.

The ventilation structure of the present invention can be modified in various ways other than the above embodiment. For example, if partition wall-shaped reinforcing plates that are orthogonal to the longitudinal direction are arranged at appropriate intervals within the cross section of the air-permeable rod member, the strength against compressive external force in the direction orthogonal to the longitudinal direction can be further improved, and it is easier to use. Become.

[Effect of the device]

 According to the ventilation structure of the present invention, its shape is simple and has strength, and its arrangement has little influence on the structure of nearby members, and construction is extremely easy. It does not change even if it is increased. In addition, no lattice frame is required at the end of the small holes, and the appearance is not damaged.
