BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of a method for fixing an aluminum sash frame according to the present invention will be described with reference to the accompanying drawings, but the present invention is not limited thereto.
FIG. 1 is a schematic front view showing an embodiment in which the present invention is applied to a sliding door aluminum sash frame serving as an entrance to a balcony on each floor of a high-rise building. 2A is a schematic vertical sectional view taken along the line YY in FIG. 1, FIG. 2B is a schematic view taken along line bb in FIG. 2A, and FIG. 2C is c in FIG. 2A. FIG. FIG. 3 is a schematic front view showing a connection state of the upper frame side fastener. FIG. 4 is a schematic front view showing a connected state of the lower frame side fastener.
[0012]
In FIG. 1, reference numeral 1 denotes an aluminum sash frame, which includes an upper frame 1a, a lower frame 1b, and left and right side frames 1c and 1d. Reference numerals 2 and 3 denote glass doors fitted in the aluminum sash frame 1. In this case, the inner glass door 2 is fixed (fitting-out), and the outer glass door 3 is a single sliding door that moves and is a sweeping type. Has become. By opening and closing the single sliding door, a person enters and exits a balcony (not shown).
[0013]
The aluminum sash frame 1 is fixed to the openings facing the balconies on each floor of the high-rise building via fasteners at the mounting points P and Q, which are located slightly inside from both ends. The lower frame 1b is fixed at attachment points R and S located slightly inside from both ends so as to be able to sway via fasteners, and both of them employ dry fixing.
[0014]
First, a method of fixing the lower frame 1b of the aluminum sash frame 1 will be described with reference to FIGS. Since the fixing means of the lower frame 1b is the same at the mounting points R and S, taking the mounting point S as an example, the cross section is approximately the upper end of the RC erection upper part 4 constituting the lower side of the opening. The L-shaped first base fitting 5 is fixed. The first base metal 5 may be fixed to the surface of the RC erection upper part 4 with a fastener such as a bolt, but is integrally fixed by being embedded in the RC erection upper part 4. At this time, it is preferable that the first base metal member 5 is welded to the reinforcing bar 4a in the RC erection upper part 4 by welding W because the fixing state becomes strong. The first base fitting 5 is made of, for example, steel and has a predetermined size and thickness.
[0015]
The horizontal surface of the first base metal fitting 5 is exposed on the surface of the RC erecting upper part 4, and the first fastener 6 having a substantially L-shaped cross section is fixed to the horizontal surface by welding W. Further, a second fastener 7 having a substantially L-shaped cross section is mounted on the lower frame 1b of the aluminum sash frame 1 in correspondence with the first fastener 6 via a bolt 8 and a nut 9 incorporated into the lower frame 1b. And fix it. When fixing the second fastener 7, the lower cover 10 having a substantially L-shaped cross section is fixed between the lower frame 1 b and the second fastener 7.
[0016]
The first fastener 6 and the second fastener 7 are made of, for example, steel and each have a predetermined size and thickness, and both have vertical holes provided with long holes for bolt insertion, respectively. The long hole of the first fastener 6 is a vertically long hole 6a which is long in the vertical direction, whereas the long hole of the second fastener 7 is formed in the horizontally long hole 7a which is long in the horizontal direction. The vertically elongated hole 6a and the horizontally elongated hole 7a are opposite to each other at the attachment points R and S, that is, at the attachment point R, the first fastener 6 is formed as a horizontally elongated hole, and the second fastener 7 is formed as an elongated hole. However, the relationship between the horizontally long holes and the vertically long holes of the first fastener 6 and the second fastener 7 may be reversed.
[0017]
The second fastener 7 is fixed to the first fastener 6 with a fastening bolt 11 and a nut 12 as shown in FIG. At this time, it is possible to finely adjust the height level of the lower frame 1b by using the vertically long hole 6a of the first fastener 6 and to adjust the height level at both the attachment points R and S. Thereby, the lower frame 1b can be leveled out. As described above, if the vertically long holes and the horizontally long holes are in the opposite relationship at the mounting points R and S, for example, the height level regulated by the horizontally long holes of the first fastener 6 on the mounting point R side is used as a reference. The horizontal frame of the lower frame 1b can be obtained only by finely adjusting the height level on the side of the mounting portion S, thereby simplifying the operation. However, it is also possible to finely adjust the height level of the lower frame 1b by using the vertically long holes of the second fastener 7 on the mounting location R side.
[0018]
After positioning the lower frame 1b with the tightening bolts 11 and the nuts 12, a washer is welded to the second fastener 7 of the horizontally long hole 7a to fix the position in the out-of-plane direction. The in-plane sway can be secured by fixing only the washer.
[0019]
Next, a method of fixing the upper frame 1a of the aluminum sash frame 1 will be described with reference to FIGS. Since the fixing means of the upper frame 1a is the same at the mounting points P and Q, the mounting point Q side will be described as an example. At the attachment point Q, a second base fitting 14 having a substantially L-shaped cross section is fixed to a lower end of the ALC plate 13 (lightweight cellular concrete) constituting the upper side of the opening with a fastener (not shown) such as a bolt. I do.
[0020]
A third fastener 15 having a substantially L-shaped cross section is fixed to the vertical surface of the second base 14 by welding W. Then, a fourth fastener 16 having a substantially L-shaped cross section is fixed to the upper frame 1a via a bolt 17 and a nut 18 which are assembled into the upper frame 1a so as to correspond to the third fastener 15. As shown in FIG. 2, an upper cover 19 having a substantially L-shaped cross section is fixed to a horizontal surface of the second base 14 with bolts or the like.
[0021]
The third fastener 15 is provided with a horizontally long hole 15a for bolt insertion in a vertical surface portion, and the fourth fastener 16 is provided with a vertically long notch hole 16a in a vertical surface and is open upward. . A vertically long hole may be employed in place of the vertically long cutout hole 16a. In the case of a vertically long hole, the horizontal and vertical holes of the third fastener 15 and the fourth fastener 16 at the mounting points P and Q are used. May be reversed.
[0022]
The fourth fastener 16 is fixed to the third fastener 15 with a fastening bolt 20 and a nut 21 as shown in FIG. At this time, the side frames 1c and 1d can be vertically set by finely adjusting the position of the upper frame 1a by using the horizontally long holes 15a in the third fastener 15. Further, the vertical sash 16a of the fourth fastener 16 is used to facilitate the fitting of the aluminum sash frame 1 into the opening, and the aluminum sash frame 1 is finely adjusted when the height level of the lower frame 1b is finely adjusted. Can move up and down to follow. As described above, in the case where the fourth fastener 16 employs a vertically long hole instead of the vertically long cutout hole 16a, and the relationship between the horizontally long hole and the vertically long hole is reversed at the attachment points P and Q. For example, with reference to the position regulated by the vertically long hole of the third fastener 15 at the mounting point P, the vertical positioning of the side frames 1c and 1d can be performed only by finely adjusting the verticality at the mounting point Q side. Therefore, the work is simplified. However, it is also possible to finely adjust the verticality of the side frames 1c and 1d by using the horizontally long holes of the fourth fastener 16 on the mounting point P side.
[0023]
In order to improve the bonding strength between the fourth fastener 16 and the third fastener 15, the vertical surfaces may be welded last. Further, it is preferable that the washer 20a interposed between the connecting portions is also welded. Thereby, the proof stress against wind pressure can be further increased.
[0024]
In the above example, the lower frame 1b performs horizontal positioning and the upper frame 1a performs vertical positioning. Conversely, the upper frame 1a performs horizontal positioning and the lower frame 1b performs vertical positioning. May be. In any case, each tightening bolt is temporarily fixed in a state where horizontal extension and vertical extension are associated with each other. After the aluminum sash frame 1 is properly positioned, the tightening bolts are fully tightened, and thereafter, as described above. Attach the connection parts to complete the installation. In FIG. 2, reference numeral 22 denotes a draining member attached to the lower frame 1b with screws or the like, and reference numeral 23 denotes a seal member provided at a required location.
[0025]
In this manner, the upper frame 1a of the aluminum sash frame 1 is connected to the ALC plate 13 which forms the upper side of the opening through the third fastener 15 and the fourth fastener 16 and the second base 14. And the lower frame 1b of the aluminum sash frame 1 constitutes the lower side of the opening through the first fastener 6 and the second fastener 7 and the first base 5. It can be dry-fixed to the RC erection upper part 4 at two places.
[0026]
In the fixing portion of the upper frame 1a, the second base metal member 14 is firmly fixed to the ALC plate 13, and the third fastener metal member 15 and the fourth fastener metal member 16 are not only tightened by the fastening bolt 20 but also mutually fixed. , The mounting strength is remarkably increased as compared with the prior art. Further, in the fixing portion of the lower frame 1b, the first base metal member 5 is firmly fixed to the RC erecting upper part 4, and the first fastener metal member 6 and the second fastener metal member 7 can be swayed by the fastening bolt 11. It is possible to cope with in-plane deformation due to earthquake by fixing it properly. As a result, it was confirmed that the aluminum sash frame 1 was firmly attached to the opening of the skeleton, and sufficient strength was obtained even when a high-rise building received a strong wind pressure (2400 Pa to 6000 Pa). found.
[0027]
In addition, since it is a dry fixing method without using any conventional filling mortar, the filling mortar does not crack or peel off after construction, and it can always maintain appropriate quality after construction, Quality control is also easy.
[0028]
Furthermore, since the aluminum sash frame 1 is attached at only two locations P and Q on the upper frame 1a and two locations R and S on the lower frame 1b, the construction is simple, the construction period can be shortened, and the construction cost is reduced Can be achieved.
[0029]
In the above embodiment, the example is applied to the aluminum sash frame for the sweeping type external sliding door, but the present invention is not limited to this, and the aluminum sash frame for the sweeping type sliding door and the like. It can be widely applied to aluminum sash frames for various windows.
[0030]
