By the way, in such a curtain wall, the impression given from the appearance is emphasized. Therefore, for example, in order to configure a curtain wall that gives a simple and sharp impression even if an opening / closing window is provided, the arrangement of each member and the reduction in the number of parts are technical issues.
However, in the curtain wall as described in Patent Document 1, since the window opening frame is formed by the vertical and invisible, the vertical and vertical around the window sash composed of the shoji and the window frame. Both innocents will exist. For this reason, on the exterior from the inside and outside, the finding dimension of the members around the window sash is increased, which may give a complicated impression.
Moreover, in the curtain wall as described in Patent Document 1, in addition to the upper frame, the lower frame, and the left and right vertical frames constituting the window frame of the window sash, the window frame is fixed to the vertical and invisible eyes and both of them. Because of the use of brackets, etc., the number of parts used is large, making it difficult to improve workability and reduce the cost of the product.

  An object of the present invention is to provide a curtain wall capable of giving a simple and sharp impression, improving workability and reducing the cost of a product.

  The curtain wall of the present invention is a curtain wall panel, a vertical member and a horizontal member that support the curtain wall panel, an opening / closing window portion, and the opening / closing window portion is attached to one of the vertical member and the horizontal member. A window frame, the open / close window portion includes a rectangular frame-shaped window frame, and a shoji that is opened and closed with respect to the window frame, and the window bracket is formed of the four sides of the window frame. Two sides for mounting opposite to each other are attached to one of the vertical member and the cross member, and two sides of the window frame facing each other other than the two sides for mounting are the above It is characterized in that it is placed against the curtain wall panel through a sealing material.

According to the present invention, the two sides for attaching the window frame are attached to any one of the vertical members such as the vertical and the middle bone and the horizontal members such as the eyeless and the horizontal rail by the window fitting. Therefore, a part for attaching the window frame to either the longitudinal member or the transverse member is not required, and the number of parts can be reduced. As a result, it is possible to improve workability by reducing the assembly man-hours, reduce the number of parts, and reduce the cost of products resulting from the reduction of the assembly man-hours.
And the two sides for window frame abutment are only accommodated against the curtain wall panel via a sealing material, so a vertical member is provided between the window frame abutment and the curtain wall panel. And the other of the cross members is not interposed. For this reason, the exterior and interior of the curtain wall can be simplified, and a sharp impression can be given as if the open / close window is floating between the curtain wall panels.

In the curtain wall according to the aspect of the invention, the window fixture may be any one of a projecting portion forming member that forms a projecting portion projecting from the two mounting sides, and the projecting portion forming member as the vertical member or the horizontal member. It is preferable to provide the connection body connected to one side.
According to such a configuration, for example, it is not necessary to form a protrusion on the window frame side, and the width dimension (finding dimension) of the window frame can be reduced. For this reason, the window frame can be made inconspicuous in the portion where the opening / closing window portion and the curtain wall panel are pressed against each other.

In the curtain wall of the present invention, a pressing edge is attached to one of the vertical member and the horizontal member, and the protrusion is formed between one of the vertical member and the horizontal member and the pressing edge. It is preferred that the member is arranged.
According to such a configuration, a concave groove can be formed between one of the vertical member and the cross member and the pressing edge by attaching the pressing edge to one of the vertical member and the cross member. And by arranging the projecting portion of the projecting portion forming member in the concave groove portion, a sealing material or a backup material is disposed between one of the vertical member and the transverse member and the projecting portion, or between the pressing edge and the projecting portion. A gap can be formed. Therefore, the indoor / outdoor communication between the opening / closing window portion and one of the vertical member and the horizontal member can be easily blocked only by closing the gaps with a backup material, a sealing material, or the like.

In the curtain wall of the present invention, when the two attachment sides are attached to the vertical member, the connecting body includes a connector for connecting the protruding portion forming member to the vertical member, and the protruding portion forming member. A support tool connected to the vertical member, and the support tool supports the vertical load of the opening / closing window portion supported by the vertical member in a state where the protrusion forming member is connected to the vertical member by the connection tool. It is preferable that the connector has a pressure receiving piece that supports the projecting portion forming member from the indoor side or the outdoor side and receives wind pressure applied to the opening / closing window portion.
According to such a configuration, for example, when the wind pressure (wind load) and the vertical load are supported by one connecting member, the shape of the connecting member becomes complicated, and the rigidity capable of supporting both loads is ensured. The connecting member is enlarged. On the other hand, in this invention, since each load can be shared and supported with a connection tool and a support tool, each shape of a connection tool and a support tool can be simplified, and it can reduce in size. Therefore, the support piece of the support tool can be disposed closer to the vertical member, and a large vertical load can be supported without increasing the size of the support tool.
Further, since the support tool only needs to support a vertical load, it is not necessary to connect the support tool to the vertical member with a screw or the like, and the number of man-hours to be connected can be reduced. Then, while supporting the support member connected to the protruding portion forming member with the vertical member, the protruding portion forming member can be connected to the vertical member by the connecting member, and the load of the opening / closing window portion is separately supported by an operator or the like. However, since it is not necessary to perform the connecting work of the connecting tool, the connecting workability can be improved.

Further, in the curtain wall of the present invention, when the two sides for attachment are attached to the cross member, the connecting body is an upper side that connects the protruding portion forming member to the cross member on the upper side of the window frame. A pressure-receiving piece that receives a wind pressure applied to the opening and closing window portion; and a lower-side connection tool that connects the protruding portion forming member to the cross member on the lower side of the window frame. Preferably, the lower connector has a pressure receiving piece that receives wind pressure applied to the opening / closing window portion, and is placed on the cross member to support a vertical load of the opening / closing window portion.
According to such a configuration, the lower connection tool can be placed on the cross member to support the vertical load of the opening / closing window part, and the wind applied to the opening / closing window part on the upper side of the window frame by the pressure receiving piece of the upper connection tool. The pressure can be received, and furthermore, the wind pressure applied to the opening / closing window portion on the lower side of the window frame can be received by the pressure receiving piece of the lower connector.

In the curtain wall of the present invention, the shoji includes a shoji and a face material held by the shoji, and the shoji is directed toward the window frame so as to cover the window frame in a window closed state. It is preferable to have an extended indoor piece or outdoor piece.
According to such a configuration, the indoor side portion or the outdoor side portion of the movable shoji screen on the movable side covers the fixed side window frame when the window is closed, so that the fixed side window frame is conspicuous on the appearance from the inside or outside. Without impressing, it is possible to give an impression that the movable shoji screen is emphasized more than the fixed window frame. For example, when the indoor piece portion is disposed on the indoor side of the window frame, the movable shoji screen can be emphasized more than the fixed-side window frame from the indoor appearance. Further, for example, when the outdoor piece is disposed on the outdoor side of the window frame, the movable side shoji can be emphasized more than the fixed-side window frame in terms of the external appearance.

In the curtain wall according to the aspect of the invention, it is preferable that the window frame is configured by a quadruple frame of an upper frame, a lower frame, and left and right vertical frames, which are shapes having the same cross-sectional shape.
In addition, it is preferable that the heel frame is configured by a four-round framework of an upper ridge, a lower ridge, and left and right vertical ridges, which are sections having the same cross-sectional shape.
According to such a configuration, the structural members of the window frame or the shoji-koji have the same cross-sectional shape. Therefore, it is possible to reduce the cost of the product by sharing the parts and improve the workability by improving the compatibility of the parts. It can give a simple and sharp impression with a uniform appearance.

Therefore, the indoor / outdoor communication between the opening / closing window portion 4 and the stand 25 can be easily blocked by simply closing the gaps with the backup material 10A, the sealing material 10B, or the like.

(4) Since the connecting tool 521 that supports the wind pressure and the supporting tool 522 that supports the vertical load are configured by separate brackets, the shapes of the connecting tool 521 and the support tool 522 are bent into an L shape or a lightning bolt. It can be made simple and can be downsized. Therefore, the support piece 522B of the support 522 can be disposed closer to the vertical body 251 and a large vertical load can be supported without increasing the size of the support 522.
Further, since the support tool 522 only needs to support a vertical load, it is not necessary to connect the support tool 522 to the vertical 25 with the screw 11 or the like, and the number of connecting steps can be reduced. The support tool 522 connected to the square pipe 51 can be connected to the square pipe 51 by the connection tool 521 while supporting the support tool 522 with the vertical 25, and the load of the opening / closing window portion 4 is separately supported by an operator or the like. Since it is not necessary to perform the connecting work of the connecting tool 521, the connecting workability can be improved.
(5) Since the indoor piece portion 433E of the movable shoji 43 on the movable side covers the fixed-side window frame 44 in the window closed state, the fixed-side window frame 44 is not conspicuous from the indoor appearance. An impression that the shoji screen 43 is emphasized more than the window frame 44 on the fixed side can be given.
(6) The upper rod 431, the lower rod 432, and the left and right vertical rods 433, 434 have the same cross-sectional shape, and the upper frame 441, the lower frame 442, and the left and right vertical frames 443, 444 have the same cross-sectional shape. Because it is a shape material, it is possible to improve the workability by reducing the cost of products by sharing parts and improving the compatibility of parts, and in appearance, give a simple and sharp impression with a sense of unity around the face material 42 Can do.
