BACKGROUND OF THE INVENTION
The present invention relates to a dirt prevention structure for an outer wall, and more particularly to a dirt prevention structure for a residential outer wall provided with a sash window or the like, or an outer wall of a building formed of a curtain wall. Specifically, for example, it can be used for an outer wall antifouling structure comprising an antifouling panel using a plurality of glass panels and a photocatalyst.
[0002]
[Background]
In recent years, outer walls of houses and buildings have been formed with antifouling panels using a photocatalyst. Such an antifouling panel is provided with an antifouling effect by a photocatalyst by coating a titanium oxide paint on the surface of a metal plate, and can be expected to be effective in reducing cleaning costs and the like.
[0003]
[Problems to be solved by the invention]
By the way, as an outer wall of a building, a glass panel is often combined with an antifouling panel made of a metal plate from the viewpoint of lighting and design.
However, when the antifouling panel is arranged on the upper side of the glass panel, the dirt on the antifouling panel is easily washed away by rainwater, so that the rainwater containing the dirt reaches the glass panel and the glass surface is covered. On the other hand, there is a problem of getting dirty.
[0004]
Therefore, it is conceivable that a bowl-shaped draining member is provided between the glass panel and the antifouling panel, and the rainwater containing dirt is dropped downwards. Since it is returned to the panel side, it is still impossible to effectively prevent the glass surface from becoming dirty.
[0005]
Such a problem appears particularly prominently when an antifouling panel is used, but when a stone panel or an aluminum metal panel is arranged on the upper side of the glass panel, or in a house, etc., mortar or siding This may also occur when a sash window provided with a glass shoji is provided on the outer wall made of the like.
[0006]
An object of the present invention is to provide an outer wall antifouling structure that can reliably prevent the glass panel forming the outer wall from becoming dirty.
[0007]
[Means for Solving the Problems]
An outer wall dirt preventing structure of the present invention is an outer wall dirt preventing structure formed including a glass panel and an upper outer wall portion of the glass panel , and is provided on a cross member that holds the upper edge of the glass panel. A horizontal part that receives the water that passes over the seal part between the horizontal member and the lower edge of the outer wall part, and a drain part that drains the water that has flowed into the horizontal part downward, avoiding the glass panel below the horizontal part It is characterized by having.
[0008]
According to the present invention, dirty rainwater or the like that tries to reach the glass panel through the wall surface is received by the recumbent portion provided on the upper side of the glass panel, and then the drainage portion is discharged from the recumbent portion. Since the water is surely drained downward, there is no possibility that dirt is deposited on the glass panel, and there is no fear of the glass panel becoming dirty.
Then, by producing the cross member with an extruded shape member or the like, the recumbent portion is integrally provided simultaneously with the production of the cross member, so that the recumbent portion can be easily formed. In addition, even when another member is attached to the cross member to form the recumbent portion, such a separate member can be securely attached to the cross member along the longitudinal direction (transverse direction), so that the recumbent portion is easy. It does not cause problems such as failure or malfunction.
[0009]
In the dirt prevention structure of the present invention, it is preferable that a guide portion for guiding the flow of water from the recumbent portion to the drainage portion is provided.
In such a configuration, by providing the guide portion, there is no possibility that rainwater or the like leaks from between the recumbent portion and the drainage portion, and drainage can be performed more reliably.
[0011]
On the other hand, the drainage part may be provided along a sealing material that seals a vertical edge of the glass panel.
Although the surface of the sealing material is easily contaminated by oil and fat, in such a configuration, rainwater or the like flows down along the surface of the sealing material, so that the contamination on the sealing material can be washed off well.
[0012]
On the other hand, the drainage portion may be a hollow portion of a vertical member provided on the outer wall, and in such a case, there is no fear that the rainwater that flows down is scattered by the influence of wind or the like. Sexually improves.
[0013]
In the antifouling structure of the present invention, a photocatalytic coating may be applied to the upper wall surface portion of the glass panel.
In such a configuration, rainwater or the like containing a lot of dirt flows down from the wall portion coated with the photocatalyst, but it can be ensured that the rainwater does not reach the glass panel by the side wall portion. Therefore, the maintenance cost for cleaning the outer wall surface is greatly reduced.
[0014]
