  However, in the above-described curtain wall, in the case of the structure of fixing the bracket of (1) to the outer surface, the bracket itself is exposed to the outer surface, so the appearance is deteriorated and the design of the appearance is degraded. There was a problem that. In addition, in this case, since a bracket is required for each position, there is a disadvantage that the cost for parts increases and the construction time is also increased.

Further, in the case of the structure in which the right member and the left member of the standing are integrated by fastening the screws or the like as in the above (2), the right member and the left member of the standing are restrained. Therefore, there is a problem that the right member and the left member do not shift relative to each other, and it is not possible to realize the follow-up property of the interlayer displacement and the absorption structure such as the thermal expansion of the cross member (eyeless).
Furthermore, in the case of the above structure (3), the number of bracket members provided in a square can be reduced to half as compared with, for example, the above structure (1), but still part of the bracket is exposed to the outside Therefore, there is a problem that the design of the appearance is impaired, and there is room for improvement in that point.

And it is reinforced by the connection flange by which the indoor side end plate to which a stand and a housing are connected is tightened together, and it becomes a structure which raised rigidity. Therefore, since the wind load received by each side (fixed side member and movable side member) can be transmitted to the housing via the rigid high co-tightening portion, the wind pressure resistance of the side can be increased.

Further, in the case of the side according to the present invention, as described above, the connecting flange has the function of transmitting the wind pressure strength. And since the connecting flange extends from the inner surface facing inward of the movable member to the fixed member in the longitudinal direction, the conventional iron external bracket provided on the outside of the member is unnecessary. become. Therefore, the connecting flange can be formed of the same material as aluminum and the like as the vertical body, and the material and the manufacturing cost can be reduced, and the workability can be further improved.

  And it is reinforced by the 2nd connection flange 23B by which the indoor side end plate 14A to which the cross 2 and the housing 5 are connected is tightened together, and it becomes a structure which raised rigidity. Therefore, since the wind load received by each side 2 (the fixed side member 11 and the movable side member 12) can be transmitted to the housing through the rigid joint portion with high rigidity, the wind pressure of the side 2 can be increased. it can.

  In addition, in the form 2 of the present embodiment, as described above, the second connection flange 23B has a function of transmitting the wind pressure strength. And since the second connecting flange 23B extends from the inner surface of the movable member 12 facing inward to the fixed member 11 in the blind axial direction P, it is provided on the outer side of the member 2 Eliminates the need for traditional iron external brackets. Therefore, the connection flange 23 can be formed of the same material as aluminum and the like as the vertical main body, the material and the manufacturing cost can be reduced, and the workability can be further improved.

  Furthermore, in the present embodiment, the joint sleeves 21 and 22 including the connecting flanges 23A and 23B are embedded in the cross 2 and can be hidden so as not to be exposed to the outside of the cross 2 to improve appearance in appearance It is possible to eliminate the conventional external bracket.

  Further, in the present embodiment, since the fixed side joint sleeve 21 and the movable side joint sleeve 22 are separate members with respect to the fixed member 11 and the movable member 12, respectively, the joint sleeves 21 and 22 are fixed. As compared with the case where the members 11 and 12 are integrally formed, a complex-shaped mold is not required. In addition, since the joint sleeves 21 and 22 may be attached to the cross members 11 and 12 at the time of construction, the transportability of the cross members 11 and 12 can be improved.

Further, in the present embodiment, since the joint sleeves 21 and 22 can be mounted on both the fixed member 11 and the movable member 12, the balance of the rigidity of both can be stabilized. For this reason, the wind pressure resistance performance of the welt 2 can be enhanced, and deformation such as twist of the welt 2 can be suppressed.
In addition, since one type of joint sleeve can be shared by the fixed member 11 and the movable member 12, the joint sleeve can be manufactured with one type of mold material.

  Further, in the present embodiment, the self weight receiving piece 32 of the movable side joint sleeve 22 mounted on the movable method standing member 12 is upward on the self weight receiving piece 31 of the fixed side joint sleeve 21 mounted on the fixing method upright member 11. The movable weight of the curtain wall 1 received by the movable member 12 can be efficiently transmitted to the fixed member 11 via the movable joint sleeve 22 and the fixed joint sleeve 21.

  Further, in the present embodiment, since the joint sleeves 21 and 22 are disposed in a state of projecting upward relative to the fixing direction member 11 and the movable direction member 12, they are provided on the upper side with respect to those projecting portions. The side walls 2 of the frame unit 1A of the curtain wall 1 can be fitted and connected. In addition, when the sealing material is filled between the upper and lower frame units 1A and 1A to form a joint, the sealing material is provided on the outside of the projecting portions of the joint sleeves 21 and 22, so the sealing material is inside the cross section. Flow can be suppressed.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention.

  For example, in the present embodiment, the fixed side joint sleeve 21 is provided on the fixed side member 11. However, the fixed side joint sleeve 21 may be omitted without being provided. Further, the fixed side joint sleeve 21 is not limited to the same shape as the movable side joint sleeve 22.

  In addition, although the fixed side joint sleeve 21 and the movable side joint sleeve 22 are separately provided from the directional members 11 and 12, respectively, and are configured to be removable, the joint sleeves 21 and 22 may be separated from each other. 11 and 12 may be integrally formed. That is, as shown in FIG. 10, in the movable side wall 16B of the movable member 12, the connecting flange 23B extending inward (in the fixed member 11) in the blind axial direction P from the inner surface facing the inner side It may be integrally formed. Further, in the fixed side wall 14B of the fixing member 11, a connecting flange 23A extending integrally from the inner surface facing inward to the inner side (the movable member 12 side) in the blind axial direction P is integrally formed. It is also good.
