Description

[0001]
[Industrial application fields]
The present invention relates to a fastener for a curtain wall that is interposed between a curtain wall main body and a casing and used to fix the curtain wall main body to the casing.
[0002]
[Prior art]
As shown in FIG. 6, a washer frame 2 is constructed by connecting a receiving part 11 in a horizontal direction to the upper end of a washer part 10 whose front surface 2a has a bulging arc shape extending in the lateral direction. The support receiving piece 11 is positioned on the tightening receiving piece 4 of the L-shaped main body frame 1 constituted by standing the fastening receiving piece 4 at the tip of the mounting piece 3 arranged in the horizontal direction, There is a structure in which the tightening receiving piece 4 and the washer piece 10 are fixed to each other with screws 18 so that the main body frame 1 and the washer frame 2 are integrated with each other.
[0003]
[Problems to be solved by the invention]
In the conventional curtain wall fastener, the connection bolt is passed through the tightening receiving piece 4 and the washer 10 through the bracket provided on the curtain wall body, and the connection nut is screwed to the bolt end protruding from the tightening receiving piece 4. The through holes 6a and 6b through which the connecting bolts 8 pass are screwed to each other for the purpose of fixing the curtain wall main body to the casing by fastening. It must be constituted by a horizontally long slot provided in the tightening receiving piece 4 and the washer piece 10 integrated together.
[0004]
On the other hand, the contact surface (front surface) of the washer part 10 with the bracket is formed in a bulging arc shape so that the bracket and the tip edge of the contact surface are always in line contact and the curtain wall body is attached to the housing via the fastener. However, if the through holes 6a and 6b are formed as horizontally long holes in order to make the position adjusting function, sometimes the contact surface of the washer part 10 does not come into line contact with the bracket. , Point contact at multiple points, and the ideal tightening state by connecting bolts is not achieved.
[0005]
The present invention has been made by paying attention to the drawbacks of such a conventional example.
[0006]
[Means for Solving the Problems]
A washer frame is formed by connecting a receiving part piece in the horizontal direction to the upper end part of the washer part piece whose front surface has a bulging arc shape along the horizontal direction, and the receiving part piece of the washer frame is arranged in the horizontal direction. The washer piece is configured by positioning the fastening receiving piece on the tip of the attached fitting piece and positioning it on the fastening receiving piece of the L-shaped body frame, and combining the body frame and the washer frame with each other. A through hole of a connecting bolt for connecting a curtain wall is provided at the front edge of the front surface in contact with the curtain wall main body, and a screw for screwing the connecting bolt is engraved on one side of the tightening receiving part of the through hole. A horizontally long adjustment hole in which the through hole partially coincides is provided in the tightening receiving part piece arranged on the rear side of the washer part piece.

【Example】
The drawings show an embodiment of a fastener for a curtain wall according to the present invention, FIG. 1 is a longitudinal sectional view in use, FIG. 2 is a partially cutaway plan view, FIG. 3 is a perspective view of a washer frame, and FIG. FIG. 5 is a perspective view showing the relationship between the main body frame and the washer frame. FIG. 6 is a longitudinal sectional view of a conventional example.
[0008]
In the drawing (members corresponding to conventional examples are indicated by the same reference numerals), A is a curtain wall fastener, and the fastener A is configured by combining the main body frame 1 and the washer frame 2 with each other. Is composed of an L-shaped body in which a fastening receiving piece 4 is erected at the tip of the mounting piece 3 arranged in the horizontal direction. The mounting piece 3 has a through hole 6 of a fixing bolt 5 for fixing to the housing B. In addition, the tightening receiving piece 4 is provided with a pair of adjustment holes 9 and 9 of a connecting bolt 8 for connecting the bracket 7 of the curtain wall main body C.
[0009]
The main body frame 1 is made of steel, and the adjustment hole 9 is made of a horizontally long slot. Further, the reason why the adjustment holes 9 are paired is that in the embodiment, each of the pair of unit bodies C ′ and C ″ constituting the curtain wall main body C is attached by the washer frame 2 in the bracket 7. The adjustment hole 9 and the washer frame 2 may have a single structure.
[0010]
In the washer frame 2, a receiving part 11 is continuously provided in a horizontal direction at the upper end of a washer part 10 having a front surface 2 a formed into a bulging arc shape along the lateral direction, and the washer part 10 of the receiving part 11 is provided. The receiving piece 12 is erected at the tip of the side, and the cross section of the front end 2a ′ of the front face 2a that is in contact with the curtain wall main body C of the washer piece 10, that is, the bracket 7, passes through the connecting bolt 8. A through hole 16 is provided, and a screw 13 for screwing the connecting bolt 8 is engraved on the tightening receiving piece 4 side (the back side of the washer piece 10) of the through hole 16.
[0011]
Thus, the attachment piece 3 is fixed to the housing B by the fixing bolt 5, and the upper end of the tightening receiving piece 4 of the main body frame 1 is formed at the corner formed by the washer piece 10 and the receiving piece 11 of the washer frame 2. The main body frame 1 and the washer frame 2 are combined so that the connecting bolt 8 is screwed into the screw 13 through the adjustment hole 9 from the tightening receiving piece 4 side, and the through hole 16 is passed through the main body frame 1. And the washer frame 2 are temporarily fixed to each other, and each washer 2 is moved with respect to the tightening receiving piece 4 along the adjustment hole 9 to adjust the position, and then the height adjustment bolt 14 provided in the curtain wall main body C is received. The connecting bolt 8 is placed on the support piece 11 so that the main body C is hooked to the fastener A, and the connecting bolt 8 is passed through the through hole 15 provided in the bracket 7 on the main body C side. Curtain wall body by screwing and tightening the connecting nut 17 to the tip A is attaching to the skeleton B.
[0012]
【The invention's effect】
Since the present invention is configured as described above, it is possible to adjust the position of the washer frame by freely moving the washer frame with respect to the main body frame. Can do.
[0013]
As a result, it is sufficient that the through hole provided in the washer part of the washer frame is formed with the minimum necessary diameter at the front edge of the front face of the washer part that is the contact edge of the curtain wall body. Only the leading edge of the front surface of the bulging arc shape is linear so that the piece comes into contact with the curtain wall main body or the bracket, so that there is no backlash, and a curtain wall with a stable mounting state can be obtained.
[0014]
In addition, since the main body frame and the washer frame can be temporarily fixed by the connecting bolt by using the screw of the through hole, there is no inconvenience in handling.
