  However, in the outer wall described in Patent Document 1, each sealing material is provided at a position that enters the indoor side from the outdoor surface of the outer wall, and the front end of the side piece of the opening frame or the sash window frame and the window edge exterior material Since the sealing material between the portions is provided to be exposed to the outdoor space, there is a problem in that sufficient waterproofness cannot be ensured. In other words, since the sealing material is located close to the indoor space, when the sealing material is cut off due to deterioration or the like, there is a concern that rainwater or the like may immediately enter the indoor space. Furthermore, the sealing material provided exposed in the outdoor space is likely to deteriorate quickly due to the influence of temperature fluctuations, ultraviolet rays, and the like, and the water stoppage may be impaired from this point. Moreover, since the sealing material is exposed to the outdoor side, there is a problem that the appearance design of the outer wall is inferior.

  An object of the present invention is to provide a sash window that sufficiently secures water-stopping performance and is excellent in appearance design.

  The sash window of the present invention is a sash window provided with a window frame body disposed closer to a room in an opening provided on an outer wall of a building, and a panel body supported inside the window frame body, The outer wall is configured to include an outer wall housing and an outer wall finishing material that covers an outdoor surface of the outer wall housing, and the window frame body includes an upper frame body, a lower frame body, and left and right vertical frame bodies, The upper frame body, the lower frame body, and the vertical frame body include a prospective piece portion extending outwardly in the prospective direction along the opening of the outer wall, and the outdoor edge of the prospective piece portion in succession. A fixed piece portion extending along the outdoor surface of the outer wall housing and fixed to the outer wall housing is provided, and at least one of the upper frame body and the vertical frame body is located indoors relative to the fixed piece portion. A finding piece portion extending inward in the finding direction continuously to the prospective piece portion, and a finding direction of the finding piece portion A folding piece portion extending continuously to the outside in the prospective direction and continuously extending from the end, and the prospective piece portion, the finding piece portion, and the outdoor surface having a substantially concave cross section recessed from the folded piece portion to the indoor side are formed, The outer wall finishing material at a position corresponding to at least one of the upper frame body and the vertical frame body includes an outer surface portion covering the fixed piece portion of the window frame body, and the prospective piece portion continuous to the outer surface portion. A folding portion extending to the indoor side of the prospective direction, and an indoor side edge of the folding portion is connected to the finding piece portion of the window frame.

  Here, the panel body supported on the inner side of the window frame body may be a face material such as a glass panel which is supported by the window frame body so as to be immovable and forms a (Fix) window. It may be one or a plurality of shojis supported by the frame so as to be opened and closed. When the panel body is a shoji, for example, a sash window of an arbitrary opening / closing type such as a sliding window, a single sliding window, an open window, and an open window can be configured.

According to the present invention, in the internal sash window disposed on the indoor side of the prospective direction from the outdoor surface of the building outer wall, the fixed piece of the window frame body is fixed to the outdoor surface of the outer wall frame. Water can be stopped between the window frame body and the outer wall housing at the fixed piece position. At this time, as a water stopping method, a sealing material is interposed between the fixed piece portion and the outer wall casing, or a waterproof sheet or waterproof asphalt that covers the surface of the outer wall casing is used to cover the fixed piece portion. A general water stop structure can be adopted. And since such a water stop structure is covered with the outer wall finishing material, it is not exposed to the outdoor space and is not easily affected by temperature fluctuations or ultraviolet rays, so that it can be prevented from deteriorating and visible from the outside. It is possible not to impair the appearance design of the outer wall.
Further, in the upper frame body and the vertical frame body of the window frame body, a bent portion of the outer wall finishing material is provided along the prospective piece portion, and the indoor side edge of the bent portion is located on the window frame body finding piece portion. By connecting to, the distance from the outdoor space outside the bent portion to the water stop position in the fixed piece portion, and the distance from the water stop position to the indoor space can be increased, respectively. Water stop performance can be improved compared to sash windows. That is, even if rainwater enters from between the front end of the bent portion of the outer wall finishing material and the finding piece portion of the window frame body, this rainwater is between the prospective piece portion of the window frame body and the bent portion of the outer wall finish material. It is necessary to move a long distance until it reaches the water stop position through the space between the fixed piece and the outer wall finishing material, so that rainwater does not easily enter the water stop position. ing. Further, even if rainwater reaches the water stop position, the rain water is first blocked by the water stop structure and cannot enter between the window frame body and the outer wall housing. Furthermore, even if rainwater enters between the window frame body and the outer wall housing, the distance from the intrusion position to the indoor space is at least the thickness dimension of the outer wall housing. The possibility of rainwater intrusion can be almost eliminated. Moreover, since the water stop position is covered with the outer wall finishing material, it is possible to reduce the influence of wind pressure and atmospheric pressure difference in the outdoor space, and from this point, it is possible to prevent rainwater from entering the indoor space.

  In addition, in the upper frame body and the vertical frame body of the window frame body, the prospective piece portion, the finding piece portion, and the folded piece portion form an outdoor surface having a substantially concave cross section that is recessed toward the indoor side. By inserting the bent part of the outer wall finishing material into the wall and finding the indoor side edge of the bent part and connecting it to the piece part, express the profound feeling of appearance by the expected size of the bent part of the outer wall finishing material The appearance design of the outer wall can be further improved. At this time, since the bent portion of the outer wall finishing material is inserted into the recess of the outdoor surface of the upper frame or the vertical frame, the indoor side edge (the end) of the bent portion can be made invisible from the outdoor side. Therefore, the design can be improved. In addition, by appropriately setting the expected position of the finding piece part and the expected dimension of the folded piece part, the expected dimension of the bent portion of the outer wall finishing material and the expected position of the panel body can be set independently and arbitrarily. . That is, if the expected position of the locating piece part is moved to the indoor side and the expected dimension of the folded piece part is lengthened, the expected dimension of the bent part can be increased without changing the expected position of the panel body. If the expected dimension of the folded piece is made longer without changing the expected position of the part, the expected position of the panel body can be changed to the outdoor side without changing the expected dimension of the bent part. This makes it possible to adjust the expected position of the panel body according to the thickness dimension of the outer wall, the type of the panel body, the finish on the indoor side, etc., while improving the appearance design of the outer wall and window. The degree of design freedom can be increased.
