Abstract

PROBLEM TO BE SOLVED: To maintain beautiful appearance of an external wall surface without intrusion of rain water etc., to an eaves back space by a level of an eaves ceiling and eliminate a large-scale ventilating bed. SOLUTION: Wall side ventilation structure is devised to carry out eaves back ventilation by forming a clearance B between a base part of an eaves ceiling 2 and an exterior wall 1. At this time, a bed material 4 is installed on an external wall surface on the lower side of the base part of the eaves ceiling 2, a lengthy decorative material 3 is installed in such a way to cover this bed material 4, and a ventilating passage with a height difference from a lower part of this lengthy decorative material 3 to an eaves back space above the eaves ceiling 2 through the clearance B is formed. Consequently, watertightness is improved without intrusion of rain water etc., to the eaves back space. Additionally, as the lengthy decorative material 3 is arranged on the lower side of the base part of the eaves ceiling 2, a designing property is improved without exposure of the neighbourhood of an upper end of the exterior wall surface. Additionally, as the ventilating passage 17 is formed as mentioned above, it is not necessary to assemble a large-scale ventilating bed on the back of the eaves ceiling, and accordingly, construction is facilitated.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall-side ventilation structure.

[0002]

2. Description of the Related Art A conventional wall-side ventilation structure forms a gap between a base of an eaves ceiling 60 and an outer wall panel 61 as shown in FIG. I can do it. The ventilation base includes a wall marginal edge 62 attached to the eaves ceiling, and a base material 6 attached above the outer wall panel 61 for attaching the wall marginal edge 62.
3, an L-shaped piece member 65 interposed between both members so that an air passage 64 is formed between the wall edge 62 and the base member 63, and a long plate 66 for covering the upper surface of the piece member 65. Composed of members. Further, the lower end of the base material 63 is fitted and attached to the step 67 formed on the upper end of the outer wall panel 61.

[0003]

However, depending on the level of the eaves ceiling 60, rainwater or snow may enter from the joint A between the base material 63 and the outer wall panel 61 when there is a strong wind, and there is a problem in watertightness. Further, since the lower end of the base material 63 located at the joint A is visible from the outside, the outer wall panel 6
There is a problem that the appearance of the outer packaging material of No. 1 is deteriorated. In addition,
In order to solve this problem, there is a structure in which a roof curtain plate similar to the exterior material of the outer wall panel 61 is attached to the surface of the base material 63, but it is costly. In addition, it is necessary to assemble a large-scale ventilation base made of many members as described above on the eaves ceiling, which makes the construction difficult.

Therefore, an object of the present invention is to prevent rainwater and the like from entering the space behind the eaves depending on the level of the eaves, maintain the aesthetic appearance of the outer wall surface, and eliminate the need to form a large ventilation base behind the eaves. The purpose is to provide a ventilation structure.

[0005]
