Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for preventing stains on an outer wall, and more particularly to a structure for preventing stains on an outer wall of a house provided with a sash window or the like or an outer wall of a building formed by a curtain wall. Specifically, for example, it can be used for a stain prevention structure of an outer wall composed of a plurality of glass panels and an antifouling panel using a photocatalyst.

[0002]

2. Description of the Related Art In recent years, outer walls of houses, buildings, and the like have been formed with antifouling panels using a photocatalyst. Such an antifouling panel is provided with an antifouling effect by a photocatalyst by coating the surface of a metal plate with a titanium oxide paint, and can be expected to reduce cleaning costs and the like.

[0003]

By the way, as the 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, if the antifouling panel is arranged on the upper side of the glass panel, the dirt on the antifouling panel is easily washed down by rainwater, so that the rainwater containing the dirt reaches the glass panel and clears the glass surface. On the contrary, there is a problem that it gets dirty.

[0004] Therefore, it is conceivable to provide an eave-shaped drainage member between the glass panel and the antifouling panel to drop the dirt-containing rainwater downward. For example, the glass surface cannot be effectively prevented from being stained because it is returned to the glass panel side.

[0005] Such a problem is particularly conspicuous when an antifouling panel is used, but when a stone panel or an aluminum metal panel is arranged above a glass panel,
Further, in a house or the like, there is a possibility that a sash window having a glass shoji is provided on an outer wall made of mortar or siding.

SUMMARY OF THE INVENTION An object of the present invention is to provide a structure for preventing contamination of an outer wall which can reliably prevent a glass panel forming the outer wall from being stained.

[0007]

According to the present invention, there is provided a dirt preventing structure for an outer wall, which is a dirt preventing structure for an outer wall including a glass panel. And a drainage part for draining water flowing into the gutter part downward while avoiding the glass panel.

According to the present invention, dirty rainwater or the like, which tends to reach the glass panel along the wall surface, is received by the gutter provided on the upper side of the glass panel.
Since the water is reliably drained downward from the gutter part through the drainage part, dirt does not adhere to the glass panel, and there is no fear that the glass panel becomes dirty.

Further, it is preferable that the stain prevention structure of the present invention includes a guide portion for guiding a flow of water from the horizontal gutter portion to the drainage portion. In such a configuration, by providing the guide portion, there is no possibility that rainwater or the like leaks from between the horizontal gutter portion and the drainage portion, and drainage can be performed more reliably.

[0010] Further, it is preferable that the cross gutter portion is provided on a cross member for holding the glass panel. In such a configuration, by manufacturing the cross member from an extruded profile or the like, the cross gutter portion can be integrally provided at the same time as the production of the cross member, so that the formation of the cross gutter portion is easy. Further, even when a separate member is attached to the cross member to form the gutter portion, such a separate member can be securely attached to the cross member along the longitudinal direction (lateral direction), so that the gutter portion can be easily formed. There is no problem such as disconnection or malfunction.

On the other hand, the drainage section may be provided along a sealing material for sealing a vertical edge of the glass panel. The surface of the sealing material is easily stained by oils and fats,
In such a configuration, rainwater or the like flows down along the surface of the sealing material, so that dirt on the sealing material can be satisfactorily washed off.

On the other hand, the drainage portion may be a hollow portion of a vertical member provided on the outer wall. In such a case, there is no fear that rainwater or the like flowing down is scattered by the wind or the like. Therefore, drainage property is remarkably improved.

In the stain prevention structure according to the present invention, a photocatalytic coating may be applied to an upper wall portion of the glass panel. In such a configuration, rainwater or the like containing a lot of dirt flows down from the photocatalyst-coated wall portion, but such a gutter can surely prevent such rainwater from reaching the glass panel. Can be utilized most effectively, so that the maintenance cost for cleaning the outer wall surface and the like can be greatly reduced.
