Description

[Detailed description of the invention] The present invention relates to a curtain wall panel mounting device, in which a reinforcing frame consisting of left and right vertical reinforcing members and top and bottom horizontal reinforcing members is arranged around the four circumferences of the back side of a rectangular-shaped face plate. A bracket is attached to each corner of the reinforcing frame to connect the left and right vertical reinforcement members and the upper and lower horizontal reinforcement members, and each of the brackets is fixed to a fastener attached to a mullion, thereby reducing wind loads, etc. It is an object of the present invention to provide a curtain wall panel mounting device having sufficient strength against external forces.

Hereinafter, embodiments of the curtain wall panel mounting apparatus according to the present invention will be described in detail with reference to FIGS. 1 to 6.

FIG. 1 is a front view showing a curtain wall using a curtain wall panel 1. As shown in FIGS. 2 and 3, the curtain wall panel 1 is made of an aluminum face plate 2 and aluminum left and right vertical reinforcing members. 3, 4 and iron upper and lower horizontal reinforcement members 5,
6 and a reinforcing frame 10 framed by 6.

The surface plate 2 is formed into a rectangular shape and has a bent portion 2a whose upper end is bent inward. Further, the reinforcing frame 10 is attached to the back surface of the top plate 2 as shown in FIG. 4 A, B, and C.
0 is an upper bracket 7, each corner of which will be described later.
7 and lower brackets 8,8.

Further, numeral 9 in the figure is an aluminum horizontal frame material formed to have the same cross-sectional shape as the left and right vertical reinforcing members 3 and 4, and the horizontal frame material 9 and the left and right vertical reinforcing members 3 and 4 are shown in FIG. Attach the corner brackets 11 to the corners where the cut surfaces cut at an angle of 45° are in contact with each other.
After fitting, they are connected with screws 12. Furthermore, the upper and lower horizontal reinforcement members 5 and 6 and the left and right vertical reinforcement members 3 and 4 are connected to the upper brackets 7 and 7 as described above.
The reinforcing frame 10 is further strengthened by being connected by bolts and nuts via the lower brackets 8 and 8, and by fixing the lower horizontal reinforcing member 6 and the horizontal frame member 9 by screwing bolts and nuts 16 and 17. connected.

The attachment state of the reinforcing frame 10 constructed in this manner and the surface plate 2 is shown in FIGS. 6A and 6B. That is,
The bent portion 2a of the surface plate 2 and the mounting member 13 having an L-shaped cross section fixed to the upper horizontal reinforcing member 5 are fixed with screws 14, and an appropriate number of screws are provided in the longitudinal direction of the lower end side and the left and right ends of the surface plate 2. After inserting the provided screw portion 2b into the holes 9a, 3a, and 4a drilled at the positions corresponding to the screw portion 2b of the horizontal frame member 9 and the left and right vertical reinforcing members 3, 4, The reinforcing frame 10 is attached to the back surface of the top plate 2 by screwing nuts 15 together.

Here, of the external force such as wind load on the surface plate 2, the portions A and A separated by the two-dot chain line in FIG.
The external force that B receives is handled by the upper and lower horizontal reinforcing members 5 and 6, and the external force that B and B receives is handled by the left and right vertical reinforcing members 3 and 4, respectively. However, at this time, the upper and lower lateral reinforcement members 5,
6 uses a material stronger than the left and right vertical reinforcing members 3 and 4.

In addition, the upper and lower horizontal reinforcement members 5 and 6 and the left and right vertical reinforcement members 3,
4 is made by fixing the connecting plate 18, which is fixed to the upper and lower brackets 7 and 8 by screwing bolts and nuts 16 and 17, to the upper and lower horizontal reinforcing members 5 and 6 by welding, etc. 3 and 4 and the brackets 7 and 8 are directly fixed together by screwing bolts and nuts 16 and 17 together. In addition, 19 in the figure is a square washer.

In addition, the left and right vertical reinforcement members 3 and 4 of the upper bracket 7
An engagement groove 7a that engages with a fastener 24, which will be described later, is formed on the surface that comes into contact with the lower bracket 8, and a slit hole 8a for positioning is formed on the contact surface of the lower bracket 8 that comes into contact with a fastener 23, which will be described later. .

The state in which the curtain wall panel constructed as described above is attached to a mullion will be described with reference to FIGS. 7 to 9.

Figures 7, 8 and 9 are E in Figure 1.
-E line sectional view, F-F line sectional view, and G-G line sectional view. , 24 are fasteners fixed to the brackets 21, 22.

The above brackets 21, 22 and fasteners 23,
24 are each formed into an L-shaped cross section,
They are fixed by screwing bolts and nuts 16 and 17 through positioning slit holes 21a, 23a and 22a, 24a formed in one side surface that abuts each other.

Further, the other side surfaces of the brackets 21 and 22 have positioning slit holes 21b and 22b drilled in the other side surfaces of the brackets 21 and 22, and positioning slit holes drilled at appropriate positions of the mullion 20. It is fixed to the mullion 20 by screwing bolts and nuts 16 and 17 through 20b.

On the other hand, the lower bracket 8 of the curtain wall panel 1 is attached to the other side of the fastener 23, but this attachment is done through a positioning slit hole 23 drilled in the other side of the fastener 23.
This is accomplished by screwing a nut 17 onto a bolt 16 inserted through a slit hole 8a for positioning the lower bracket 8.

Further, the upper bracket 7 of the curtain wall panel 1 is attached to the other side of the fastener 24, but this attachment is carried out by engaging the engagement groove 7a formed in the upper bracket 7 to the other side end 24a of the fastener 24. It is accomplished by doing.

Therefore, when installing the curtain wall panel 1, first insert the engagement groove 7 of the upper bracket 7.
a to the other side end 24a of the fastener 24, and then the lower bracket 8 and the fastener 23
Since it is only necessary to secure them together by screwing together the bolts and nuts 16 and 17, the installation work can be easily performed.

In the figure, 25 is a caulking material, 26 is a backup material thereof, and 27 is a caulking material.

As described in detail above, the curtain wall panel mounting device according to the present invention reduces the wind load etc. received by the surface plate 2 by the upper and lower horizontal reinforcement members 5 and 6 and the left and right vertical reinforcement members 3 and 4.
Moreover, the upper and lower horizontal reinforcement members 5, 6 and the left and right vertical reinforcement members 3, 4 are connected via brackets 7, 8, and are fixed to the mullion 20 via these brackets 7, 8. Since it is attached to the fasteners 23 and 24,
Since it becomes possible to transmit all the external force applied to the top plate 2 to the mullion 20 side via the bracket, damage to the top plate 2 can be prevented.

In addition, the brackets 7 and 8 are the left and right vertical reinforcement members 3 and 4.
and the connection of the upper and lower horizontal reinforcement members 5 and 6, and the fastener 2
3 and 24, and is also easy to attach to the fasteners 23 and 24, which provides practical effects such as easy attachment work.
