Description

[Detailed Description of the Invention] (Industrial field of application) This invention is to install the condensation water generated in the frame part of the bay window facing the indoor side, which is installed in the frame of the building opening, to the main plate surface of the bay window. The present invention relates to a drainage structure of condensed water in a bay window that discharges without affecting.

(Problems to be solved by the invention) The vertical frame installed in the frame of the building opening and to which the bay window is attached is made of a metal such as aluminum alloy, and is arranged so that one side is in contact with the outside air and the other side faces the indoor side. In that case, dew condensation will occur on the surface of the frame on the indoor side when the indoor temperature rises outside the room.

On the other hand, the main plate such as wood horizontally arranged over the whole of the bay window extends right below the lower end of the frame, so that the main plate surface is condensed on the surface of the frame.
The water that falls along here causes the effects of pollution and corrosion.

For this reason, it is necessary to perform a treatment for discharging the condensed water at the lower end of the vertical frame without affecting the surface of the ground plate by the condensed water.

Conventionally, for example, as proposed by the applicant in Japanese Utility Model Laid-Open No. Sho 62-21279, a method of receiving condensed water by placing a saucer for condensed water on the main plate and abutting horizontally around the vertical frame has been adopted. However, it is difficult to completely collect water in the structure where the saucer is placed to face the vertical frame side like this proposal, because it is difficult to collect water completely, and it is projected on the main plate surface. This hinders the installation of objects on it, resulting in a reduction in the effective plane area of the ground plane.

This invention has been made in view of the actual situation of the invention of the above-mentioned application, and it is intended to newly propose a drainage structure that overcomes the above inconvenience.

(Means for Solving the Problem) In the present invention, a flat area larger than the cross-sectional area of the frame portion facing the indoor side of the vertical frame is given to the tray for collecting the condensed water, and this is arranged immediately below the lower end of the frame portion. As a result, the structure is such that the water collection is ensured, and at the same time, it is embedded in the surface side of the main plate so as to be substantially flush with the surface thereof, so that the installation of the object on the main plate is not hindered and the flat area can be effectively used.

The dew condensation water generated on the surface of the frame portion facing the indoor side of the vertical frame naturally falls from the lower end thereof, is directly received by the saucer having a larger area, and is discharged to the outside of the room through the saucer.

(Embodiment) The present invention will be described below with reference to the drawings illustrating an embodiment.

As shown in FIG. 1, the present invention condenses dew on the lower ends of the vertical frames F of the bay window W, which is erected adjacent to the pillar C constituting the skeleton of the building opening, and the frame parts f of the window frames F facing the indoor side. It has a structure for arranging a tray 1 for receiving water, for example, made of synthetic resin, through which condensed water is discharged to the outside of the room.

As shown in FIG. 2, the vertical frame F of the bay window W is supported by the column C of the frame of the opening and is installed around it. One side is exposed to the outside of the room, and the other side is a frame part f protruding toward the inside of the room. ing.
In the figure, 3 is a decorative material, 4 is a glass screen of the bay window W, and 5 is a lower frame of the bay window W.

The bottom plate 2 on which an object is placed is horizontally attached to the entire vertical surface of the bay window W, including the vertical frames F of the bay window W, and the lower portions of the frame portions f facing the indoor side of the F. The saucer 1 is embedded in the.

As shown in FIG. 2 and FIG. 3 which is a sectional view taken along the line XX, the plane area of the tray 1, that is, the size is the vertical frame F of the bay window W.
This is larger than the cross-sectional area of the frame portion f, and the main body of the tray 1 is installed immediately below the lower end of the frame portion f.

As shown in FIG. 3, the tray 1 has a flange 1a around its periphery.
When the flange 1a is formed, the upper surface of the flange 1a is flush with the top end surface of the base plate 2, or when the flange 1a is thin, it may be mounted on the top end.
If there is not, it is embedded and arranged as it is on the front surface side of the main plate 2.

As shown in FIG. 4, which is a sectional view taken along the line Y-Y in FIG. 2, a drain port 1b is opened on the outside of the tray 1, and a drain pipe 6 penetrating the main plate 2 is inserted into the drain port 1b. Are connected.

With the above configuration, as shown in FIG. 4, the water condensed on the surface of the frame portion f of the vertical frame F falls from the lower end into the tray 1,
It is guided to the outside of the building frame through the drainage port 1b and the drainage pipe 6.

A draining plate 7 is provided on the outside of the body under the opening, and a ground plate 2 is also provided.
Bottom plates 8 covering the bottom of the drainage pipe 6 are attached to the bottom of the drainage pipe 6, but the water falling from the drainage pipe 6 once falls below the draining plate 7 as shown in FIG. 4 and FIG. 5 which is a partially enlarged view thereof. It is received by the draining piece 7a, and the bottom plate 8 and the draining piece 7 are further received.
The water is discharged to the outside from the drainage ports 8a and 7b penetrating a.

If the condensed water is guided to the bottom plate 8 and discharged as described above, the condensed water is positively discharged through the drain pipe 6, so that there is an advantage that the backflow to the tray 1 does not occur even in a strong wind.

(Effects of the Invention) The present invention is as described above, and the flat area of the tray is larger than the cross-sectional area of the frame portion that is located on the indoor side of the vertical frame and causes dew condensation water, and the tray is directly below the lower end of the frame portion. Since it is placed almost flush with the main plate surface, it is possible to collect dew condensation water reliably and completely and discharge it outside the room, and at the same time, reduce the surface area of the main plate without reducing the surface area. It can be used effectively.
