In this way, as shown in FIG. 2, the work of attaching the outer wall panel 2.2 to the steel frame column 3 and the clearance treatment of the outer wall panel 2.2 are completed. Then, the outer wall 1 is constructed by sequentially repeating such work.

As described above, the outer wall 1 according to this embodiment
In the mounting structure of No. 3, the outer joiner 6 has the close contact portions 13a and 13a.
Since the sealing tape 16 is sealed between a and each outer wall surface of the outer wall panel 2.2, the sealing property between both outer wall panels 2.2 and the outer joiner 6 is secured at this portion. Therefore, it is possible to easily perform the sealing process on the joint portion between the outer wall panels 2 and 2.

Further, since the joint cover 7 is covered on the outer joiner 6, it is possible to omit the filling of the caulking material even when it is necessary to seal the joint between the inner joiner 5 and the outer joiner 6. While you can
The structure of the joint portion does not appear on the outer skin material 10 side of the outer wall panel 1, and the appearance of the outer wall 1 can be improved. Moreover, the split roll portions 7b and 7b of the joint cover 7 are
Since it is formed so as to close between the roll portions 13c and 13c of the outer joiner 6 and the outer skin material 10 and 10 of the outer wall panel 2.2, the sealability between the outer wall panel 2.2 and the outer joiner 6 is further improved. Can be made.

In the present embodiment, the outer joiner 6 is provided with the concave portion 14 so that the inner joiner 5 and the outer joiner 6 are coupled with each other in the gap formed between the outer wall panels 2 and 2.

The stepped portions 10a, 10a have caulking material. 21 is filled. In addition, the inner wall material 9 on the side edge portion of the outer wall panel 2.2.
An inner joiner 22 as an inner holding member is interposed between the 9 side and the steel column 3.

The inner joiner 22 is made up of an endothelium material 9 and a steel column 3.
The sandwiching portions 23, 23 sandwiched between and are fixed by being penetrated by the tapping screws 4.4.
The convex portion 24 provided between 3 and 23 is the outer wall panel 2.
It is inserted between the two. The inner joiner 22 is made of, for example, a galvanized steel sheet, and has almost the same shape as the inner joiner 5 (see FIG. 1) in the first embodiment, but the height of the convex portion 24 is the outer wall panel. Inner joiner 5 is slightly smaller than the thickness of 2
Different from

On the other hand, a coupler 25 as a second intermediate member is fastened by a drill screw 15 to the side edge portion of the outer wall panel 2.2 on the side of the outer skin 10. The coupler 25 is
For example, it is made of a material having relatively high strength such as stainless steel, and both ends thereof are bent inward in a substantially semicircular shape. A joint cover 26 as a second covering member is attached to the coupler 25.

The joint cover 26 has a slightly lower step portion 26a at the center for reinforcement, and both side edges are curved inward. Further, the joint cover 26 has flat plate portions 26b and 26b extending from both sides of the step portion 26a in parallel with the outer wall panel 2.2.
The inside of 26b and the outer wall panel 2.2 are sealed with caulking tapes 27 as a sealing material. Further, in the joint cover 26, a receiving portion 26c serving as an engaging portion is fixed inside the stepped portion 26a by a joining means such as spot welding. Like the coupler 25, the receiving portion 26c is made of, for example, a stainless steel material, and both ends thereof are bent inward in a substantially semicircular shape.

The joint cover 26 thus constructed is
By engaging the receiving portion 27c so as to cover the coupler 25, the receiving portion 27c is attached to the outer joiner 22 and covers the outer wall panel 2.2.

The joint cover 26 is attached to the inner joiner 22.
When installing it on the outer wall panel 2.2
Caulking tapes 27, 27 are attached to the 10 side, and the joint cover 26 is fitted to the coupler 25 and the receiving portion 26c as shown by the arrow in the figure. And the flat plate portion 26b.2
Attach 6b to caulking tape 27.27.

As described above, the outer wall 1 according to this embodiment
In the mounting structure of, the joint cover 26 and the outer wall panel 2.2
Caulking tape 27.2 between each outer wall
Since it is sealed by 7, it is possible to secure the sealing property between both outer wall panels 2.2 and the joint cover 26 at this part, and to easily perform the sealing process of the joint portion between the outer wall panels 2 and 2. Can be given.

Further, in this embodiment, since the joint cover 26 is attached by the coupler 25, the large outer joiner 6 (see FIG. 1) as in the first embodiment is used.
It is possible to save the material cost without having to use the reference). Further, with the above-described mounting structure, the joint structure can be formed to be significantly thinner than the joint structure in the first embodiment, and the appearance can be further improved.
