Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a drainage structure on the outer wall of a building.

[Prior Art] Window glass forming the outer wall of a building is usually attached to a sash. FIG. 2 shows an example of this, in which the window glass 1 is fixed in the groove of the sash 2 with a sealant 6. In such a window glass, dust 8 accumulates on the convex portion of the sash, and when it rains, this dust flows down the outer wall together with rainwater and may adhere to the outside wall along the way. For this reason, as shown in Figure 3, designs have been devised to eliminate protrusions where dust can easily accumulate, and designs that make it easier to drain water. There is a strong desire to improve the problem of contamination of outer walls.

[Means for solving the problem] The present invention was made with the aim of solving the above-mentioned problem caused by the draining of window glass on the outer wall of a building. An opening is provided in the plate receiving part, and the opening extends along the joint part and opens into a rain gutter provided in the main body of the sash,
The upper surface of the opening has a drainage slope that slopes downward toward the rain gutter, and rainwater on the window glass surface is guided and discharged from the opening to the rain gutter provided in the main body of the building. It provides a drainage structure.

That is, the feature of the present invention is that rainwater running down the outer wall flows behind the joints of each windowpane, so that dirt adhering to the upper windowpane flows down with the rainwater and does not stain the lower windowpane.

Next, an embodiment of the present invention will be described in detail with reference to FIG. In the figure, 1 is a window glass that forms at least a part of the outer wall of the building, 2 is a sash for attaching the window glass, and the sash 2 has a plate receiving part 5 for supporting the window glass 1 at the joint part. The window glass 1 is fixedly supported by the sealant 6.

In the plate receiving part 5 of the sash 2, an opening 4 is provided along the sash 2, that is, along the joint of the window glass 1, and on the other hand, in the main body of the sash 2, a rain gutter 3 is provided inside the sash. provided by a structure, the opening 4 is opened to the rain gutter 3,
It is constructed so that rainwater flowing down the window glass surface located at the upper part of the plate receiving part 5 is guided to the rain gutter 3 through this opening part 4 and discharged. In this case, the upper surface of the opening 4 has a rain gutter 3 so that rainwater flowing down the window glass surface can easily flow into the opening 4 at the joint.
It has a drainage slope that slopes downward towards.

The size of the gap between the openings 4 is not particularly limited, but if the gap is too small, rainwater will be subject to flow resistance from the lower surface of the openings 4, so it is usually desirable that the gap is 3 mm or more.

In the present invention, the sash 2 uses an opening 4 provided in the plate receiving part 5 and a rain gutter structure provided in the sash body, which has a water gradient that is completely opposite to that of a normal drainer, to allow rainwater flowing down the window glass surface to flow through the opening. 4 can be brought inside and drained through the rain gutter.

In addition, the rain gutter 3 of Satsushi 2 is omitted from illustration.
Rainwater collected from the opening 4 is drained for each windowpane or for a plurality of windowpanes at the side of the sash.

[Effects of the invention] As explained above, the present invention is configured so that rainwater flowing down the window glass surface is guided and drained from the opening provided in the plate holder of the sash to the rain gutter provided inside the sash at the joint. Because of this, dust adhering to the surface of the window glass can be guided to the rain gutter inside the satsushi together with rainwater during rain. This prevents dust adhering to the surface of the window glass from being washed down one after another by rainwater on the lower window glass surface or the panel surface forming the outer wall of the building, adhering to these surfaces and contaminating them. This has a particularly great practical effect on heat-reflecting glass where dust contamination is easily noticeable.

[Brief explanation of the drawing]

FIG. 1 is a longitudinal sectional view of a draining structure according to the present invention, and FIGS. 2 and 3 are sectional views of a conventional example. In the figure, 1 is a window glass, 2 is a sash, 3 is a rain gutter, 4 is an opening, and 5 is a board holder.

Claims (1)
