Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sash structure in which a shoji slide opens and closes inside a window frame attached to an outdoor opening of a building, and in particular, a high watertightness against rainwater or the like with wind pressure in a barrier-free sash in which a lower frame upper surface is formed in a substantially flat surface. Relates to the device.
[0002]
[Prior art]
The outdoor opening of a building is generally provided with a window structure in which a frame is constituted by an upper and lower frame and left and right vertical frames, and a shoji slide is opened and closed inside.
In this case, conventionally, as shown in FIG. 33, a structure in which a ridge-like rail protrudes from the lower frame sash and a door wheel attached to the lower arm of the shoji is rotated on this rail is general. .
In addition, a step is provided on the outdoor outdoor streak rail and the indoor side streak rail of the outdoor opening of the building so that the indoor side is higher, or a step is provided on the outdoor and indoor sides of the rail groove. To prevent the entry of wind and rain.
More specifically, rainwater sprayed on window glass, etc., falls along the shoji and collects in the rail groove of the lower frame, and in particular, the summing part of the shoji and inner shoji, the shoji door-tower and the vertical frame sash. The wall of the rail groove prevents the entry to the indoor side, and flows out to the outdoors by the weight of the accumulated rainwater.
[0003]
However, if a barrier-free sash structure with the upper surface of the lower frame sash formed flat is used, there is no rail groove wall, and a large amount of rainwater that falls along the shoji screen during heavy rain with wind pressure etc. There was a technical problem that rainwater infiltrates along the flow of air and the watertightness becomes a problem unless it is easy to collect on the upper surface of the lower frame sash and ensure airtightness.
In particular, the amount of water collected on the outdoor side of the lower part of the sliding shoji summons is more than before, and the summoning part has a complicated airtight and watertight structure between the inner and outer shojis. In the case of outdoor sashes, it is necessary to improve the drainage as well as the airtightness because rainwater is more easily penetrated due to wind pressure.
In addition, when it becomes a middle- and high-rise building, it receives wind pressure close to 500 Pa, and in order to prevent rainwater from entering the room, an airtight line is secured between the shoji and the window frame sash, and the upper surface of the lower frame that forms the airtight line It is necessary to provide a lower frame recess for drainage in order to ensure high drainage from the rainwater. In this case, it is also necessary to prevent rainwater flowing along the inner frame lower frame recess from entering the inside of the outer door. there were.
[0004]
[Problems to be solved by the invention]
The present invention relates to a sliding shoji that slides open and close on the lower frame surface of a sash composed of an upper and lower frame and left and right vertical frames attached to an outdoor opening of a building.
