[0002]

2. Description of the Related Art Conventionally, when an outer wall panel is mounted, as shown in FIG.
An L-shaped metal member 51 is attached to the lower end of the “0”, and the outer wall panel 52 is fixed by the metal member 51. That is, FIG.
As shown in FIG. 15, the horizontal piece 51 a of the hardware 51 is fixed to the lower frame 50 a of the beam 50 with bolts 53, and the frame 52 a near the upper part of the outer wall panel 52 is bolted to the vertical piece 51 b.
It is fixed with. As shown in FIG. 14, the metal members 51 'located at the corners of the beam 50 and the column 56 have shorter lengths, but have the same fixing structure.

[0003]

However, the hardware 5
If the load-bearing framework is mounted between the beam 50 for fixing the support 1 and the beam 55 erected thereunder, the metal frame 51 cannot be attached due to interference with the load-bearing framework, and as a result, the outer wall panel 52 cannot be mounted. was there. In addition, since the bearing framework can be provided only at the position of the partition in the middle of the building, there is a problem that the degree of freedom of the floor plan is reduced.

Accordingly, it is an object of the present invention to provide an outer wall structure to which an outer wall panel can be attached even when a load-bearing framework is attached between a pair of beams erected on the outer periphery of a building.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An outer wall structure according to an embodiment of the present invention will be described with reference to FIGS. Pillar 6 standing on the periphery of the building
With the upper beam 1 such as a lattice beam installed with a space between them
A load-bearing framework 3 is mounted between the lower beams 2 . The upper end of the outer wall panel 4 is attached to the outdoor side of the load-bearing framework 3 by using two types of upper support hardware 5, 5 '.

As shown in FIG. 2, the upper support metal member 5 is an L-shaped metal member including a vertical piece 5a and a horizontal piece 5b which are bent at substantially right angles or joined by welding. Further, two bolt insertion holes 5c, 5c are provided side by side substantially at the center and one side of the upper portion of the vertical piece 5a, respectively.
One bolt insertion hole 5d is provided on the other side of the horizontal piece 5b. The two bolt insertion holes 5c, 5c of the vertical piece 5a
The intervals are set so that they can communicate with bolt insertion holes (not shown) provided in the columns 6.

As shown in FIG. 3, the other upper supporting metal member 5 'has a vertical piece 5 like the one upper supporting metal member 5.
Although it is an L-shaped metal piece composed of a ′ and a horizontal piece 5b ′, it is smaller than one upper supporting metal piece 5. Also, two bolt insertion holes 5c 'and 5c' are provided side by side on the vertical piece 5a ', and one bolt insertion hole 5d' is provided on one side of the horizontal piece 5b '. An interval is set between the two bolt insertion holes 5c 'and 5c' of the vertical piece 5a 'so as to communicate with a bolt insertion hole (not shown) provided in a connecting member 1a of the beam 1 described later.

In the mounted state, as shown in FIGS. 4 and 5, a vertical piece 5a of one upper support metal member 5 is fixed to a column 6 supporting an end of the beam 1 with a bolt 7, and the upper end of the outer wall panel 4 is fixed. Is supported and fixed to the horizontal piece 5b by bolts 8. Also, as shown in FIGS. 6 and 7, the vertical piece 5a 'of the other upper support metal member 5' is fixed to the connecting member 1a at the intermediate portion of the upper beam 1 with bolts 7, and the outer wall panel 4 is fixed.
The upper frame 4a is supported and fixed to the horizontal piece 5b 'by bolts 8.

As shown in FIG. 10, the lower end of the load-bearing framework 3 is fixed to the lower beam 2 via a fitting 9.
Specifically, the mounting hardware 9 has a shape in which the outer surfaces of a pair of channel steel webs are joined, and the upper flange 9a and the lower frame 3a of the load-bearing framework 3 are joined by bolts 10. Also, the lower flange 9
“b” is joined to the upper frame 2 a of the beam 2 together with the lower supporting hardware 12 by the bolt 11. The lower supporting metal 12 is a substantially L-shaped metal having a vertical piece 12a and a horizontal piece 12b having two bolt insertion holes each having a length substantially equal to the lateral dimension of the load-bearing frame 3. is there. In the mounted state, the horizontal pieces 12b are interposed between the lower flange 9b and the upper frame 2a and are integrally joined by the bolts 11 so that the vertical pieces 12a face the outdoors and face upward. Also, the lower flange 9b of the mounting hardware 9 and
A spacer 15 for height adjustment is interposed between the lower support metal 12 and the horizontal piece 12b.

The lower frame 4b arranged at the lower end of the outer wall panel 4 and the upper frame 4a 'arranged below the outer wall panel 4 are both placed on the outdoor side of the bearing frame 3.
Bolts 13 are used to support and fix to the vertical pieces 12a of the lower supporting hardware 12 that have risen . Further, at places where the load-bearing framework 3 is not attached, the outer wall panel 4 is supported and fixed in the same manner as in the conventional example shown in FIGS. Further, spring washers and flat washers are used at all bolted joints.

In this embodiment, it corresponds to the position of the load-bearing framework 3.
L-shaped upper support hardware on the outer surfaces of the upper beam 1 and the column 6
Fix the vertical pieces 5a ', 5a of 5', 5 and project to the outdoor side
The outer walls are attached to the horizontal pieces 5b ', 5b of the upper support hardware 5', 5
Since the upper end of the panel 4 is supported and fixed, the lower part of the upper beam 1
There is no member that hinders the mounting of the load-bearing framework 3
A substantially L-shaped lower support between the load-bearing framework 3 and the lower beam 2.
On the upper end of the lower beam 2 with the horizontal piece 12b of the object 12 interposed
Lower support that is fixed and rises outside the load-bearing framework 3
The inner surface of the lower end of the outer wall panel 2 is attached to the vertical piece 12a of the object 12.
Since the support is fixed, the space in which the lower end of the
Vertical piece 12 of the lower supporting hardware 12 above the upper beam 2
a and the horizontal piece 12b. For this reason,
Attach the load-bearing framework 3 between the beam 1 and the lower beam 2, and
The outer wall panel 4 can be attached to the outdoor side of the framework 3.
You. The shape of the upper metal support 5 (5 ') and the number and positions of the bolt insertion holes 5c, 5d (5c', 5d ') may be changed as appropriate.
