Abstract

(57) [Summary] [Purpose] In the back mullion curtain wall,
To obtain a horizontal member roll prevention structure that prevents the horizontal member roll due to glass load without using a downstop. [Structure] A flange 10 is formed integrally with the horizontal member 1 so as to make surface contact with the outer side surface of the mullion 2 and restrain its rotation. Prevented falling.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a horizontal member tumbling prevention structure for preventing a horizontal member from tumbling due to a glass load in a back mullion curtain wall.

[0002]

[Prior Art]

 Fig. 3 shows the structure of a conventional back mullion curtain wall for preventing horizontal members from collapsing. The cross member 1 is attached to the attachment member 3 fixed to the mullion 2 via bolts 4. A glass 5 is attached to the cross member 1, and a down stopper 6 is provided to prevent the cross member 1 from rolling due to the load of the glass 5. The falling stopper 6 is attached to the outer side surface of the mullion 2 by a screw 7, and is configured to support the cross member 1 and prevent its fall.

[0003]

[Problems to be solved by the device]

 Since the conventional structure for preventing the horizontal members from rolling is constructed as described above, the downstop 6 must be manufactured as a separate part and screwed to the mullion 2 with the screw 7. For this reason, it took a lot of man-hours to manufacture and install the descent stop and to assemble it to the mullion, and this was a factor of cost increase. The present invention has been made to solve the above problems, and to obtain a horizontal member tumbling prevention structure in a back mullion curtain wall that can prevent horizontal member tumbling without using a descent stop. The purpose is.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problem, the horizontal member roll prevention structure according to the present invention is a horizontal member roll prevention structure for a back mullion curtain wall, in which the horizontal member is brought into surface contact with the outer side surface of the mullion to prevent its rotation. It is characterized in that the restraining flange portion is integrally formed.

[0005]

[Action]

 Since the cross member roll prevention structure according to the present invention is constructed as described above, the flange portion integrally formed with the cross member is in surface contact with the outer side surface of the mullion, and the glass load applied to the cross member causes Even if the cross member tries to rotate, the rotation of the cross member is restricted by the surface contact between the flange portion and the outer side surface of the mullion to prevent the cross member from rolling.

[0006]

【Example】

 1 and 2 show an embodiment of the present invention. The cross member 1 is attached to a mounting member 3 which is screwed to the mullion 2 in advance via bolts 4, and a glass 5 is fitted into the cross member 1. A flange portion 10 is formed integrally with the horizontal member 1 at a portion extending along the outer side surface of the mullion 2 so as to make surface contact with the side surface.

Then, the horizontal member 1 is attached to the mounting member 3 which is screwed to the mullion 2 by the bolt 4, and when the glass member 5 rolls down, the flange portion 10 makes surface contact with the outer side surface of the mullion 2. However, it is prevented by restraining the rotation. Therefore, unlike the conventional one, it is possible to prevent the horizontal member from being crushed without the need to use a special down-locking component.

[0008]

[Effect of the device]

 As described above, according to the horizontal member roll prevention structure of the present invention, the flange portion integrally formed with the horizontal member can prevent the horizontal member from rolling due to the glass load without using a separate component. Therefore, compared with the conventional one, it is not necessary to manufacture the downstop and to assemble it to the mullion, and it is possible to significantly reduce the number of man-hours and to achieve the effect of cost reduction equivalent to that. Play.
