However, a barrier-free type sash structure in which the upper surface of the lower frame of the sash is formed flat does not have the rail groove walls. In an outdoor sash, a middle or high-rise building receives a wind pressure of about 500 Pa. In order to prevent rainwater from entering the room due to a pressure difference due to the temperature difference between the outside and the room, secure an airtight line between the shoji and the sash frame, and high drainage from the upper surface of the lower frame that forms the airtight line It was necessary to secure the nature. In addition, 3-6
Japanese Patent Application Laid-Open No. 8285 discloses an example in which the upper surface of the lower frame of the sash (running portion of the sliding shoji) is formed substantially flat. However, since it is intended to be airtight, tight materials are provided on both sides of the projecting piece. Is a constituent requirement. As a result, the opening and closing operation force of the shoji increases due to the resistance of the tight material on both sides, and the outside material is prevented from entering the lower frame recess by the tight material on both sides of the protruding piece, so that the pressure of the outside air and the lower frame Since the pressure difference in the concave part becomes large and it is difficult to stably seal over the entire length of the protruding piece in the longitudinal direction, rainwater flows intensively due to this pressure difference from a weakly sealed part and invades the indoor side. There were technical challenges.

[0006] With this structure, a horizontal tight member provided between the sliding piece hanging down from the side wall of the rising frame on the upper portion of the lower frame base member and the indoor side wall of the shoji lower frame against wind and rainwater blown from the outdoors. An airtight line is formed of the material, and a drainage recess provided therebelow acts as a pocket for storing rainwater. In more detail, if the upper surface of the sash lower frame is made a barrier-free type with a flat upper surface, rainwater easily accumulates between the shoji and the lower frame, especially in the case of rainwater with wind pressure, a pressure difference occurs between the outside and the room If only the airtight line formed by the horizontal tight material provided on the lower frame and the sliding piece of the lower frame of the shoji, the seal part becomes wet by the capillary phenomenon when the seal part becomes wet with rainwater, and the wind pressure from the outdoor side Rainwater is pushed out into the room and it is difficult to prevent rainwater from leaking into the room.However, a drainage recess is provided almost directly below this airtight line as a pocket to allow rainwater to flow in, and a drainage recess underneath. By providing the hollow portion, rainwater is not trapped in the seal portion, and the rainwater accumulates in the drainage concave portion so that a pressure difference between the outside and the inside of the room can be countered. A horizontal tight member is provided as a sealing means between the slide piece hanging down from the indoor side wall of the sliding door lower frame and the indoor side wall of the lower frame concave portion. There is no horizontal tight material between the side wall of the lower frame recess and
Since there is a slide groove aimed at drainage, this gap allows the sliding door to open and close smoothly, and when wind pressure is applied to the door surface from the outdoor side, the indoor side wall of this slide piece and the horizontal tight material are The seal is improved by being strongly pressed, and the gap K (see FIG. 2) between the slide piece and the slide groove wall on the outdoor side increases in proportion to the wind pressure. Flows. In the present invention, since the slide piece is provided on the inner side wall of the lower frame room, it operates as follows. Referring to FIG. 15 in the case where the shoji sliding piece is on the outdoor side and FIG. 16 in the case where the shoji sliding piece is on the indoor side, a glass holding packing 71 is provided between a glass member 70 and a shoji member such as a lower sliding door frame. The gap is sealed, but when a large wind pressure is applied to the door surface, the glass is strongly pressed to the indoor side, and there is a high possibility that the outdoor seal of the packing material part is weakened, and rainwater enters from this part Will come. The lower frame has a glass frontage drainage port 73, a lower frame lower drainage port 74, and a cutout portion of a door wheel mounting portion, and the like. As shown in FIG. Since it communicates with the indoor side, the pressure difference between the glass frontage and the room increases due to the wind pressure, and a large amount of rainwater infiltrates due to the pressure difference. On the other hand, when the slide piece is provided on the indoor side wall, the inside of the lower frame communicates with the outside air as shown in FIG. It works to prevent a large amount of water from flowing out from the lower drain port to the lower frame flat surface. 15 and 16 show the cross-sections of the outer sash and the inner sash, which are arranged side by side for convenience. However, when the actual sash and the inner sash are closed, the rainwater that has entered the frame of the lower frame from the glass seal surface is used. If the slide piece falls on the flat surface of the lower frame and the slide piece is provided outside the room, it will flow into the room as it is, but if the slide piece is provided on the indoor side wall, the pressure of the glass frontage approximates the outside air In addition, the slide piece provided on the indoor side wall acts to prevent rainwater from entering the room. In addition, even if the top flat member for the shoji slide is formed integrally for the inner shoji and the outer shoji,
Each of them may be formed separately, and the drainage recess may be provided on the side of the top sliding member for the sliding door, or may be formed in combination with the lower frame base member. Also, the hollow portion of the lower frame may be provided on the lower frame base member side, or may be formed integrally with the upper sliding flat member, but the upper flat flat member for sliding sliding door and the lower frame base member are separately formed. Then, the processing of the drain port and the like becomes easy.

[0007] Here, the drain recess and the drain hollow communicate with the outside air through the lower frame outdoor drain port, and a part of the upper surface of the lower frame is cut off in accordance with the position of the combining portion of the outer sash and the inner sash. It is desirable to provide a cut-out flat surface drain port, and to cut out a part of the upper surface of the lower frame in the corner portion of the sliding door frame and the vertical frame sash in the same manner as described above to provide a corner drain port. In addition, an airtight line made of a horizontal tight material arranged between a rising piece from the base member of the lower frame and a sliding door slide piece, and an airtight line made of a vertical tight material arranged between a vertical frame recess and a sliding door door frame. It is desirable that the sliding part of the sliding door slide downward from the lower part of the side wall of the lower frame of the sliding door after forming a bent part on the indoor side so that the butted part is formed on substantially the same surface and the airtightness of the corner part is ensured. . Further, a detachable sash is easily attached and detached, and a Kendon-type sash is attached to the sash frame such as the sash frame and the lower frame in order to ensure maintainability.
