In this state, apply the presser plates 5, 5 to both edges 2, 2 of the outer wall corner 1 and the edges 6a, 6a of the outer wall panels 6, 6, and attach the presser plates 5, 5 to the omega bolts 7, 7. It was supposed to be tightened with. In addition, the numbers 8 and 8 in the figure are wall frames, 9,
Reference numeral 9 denotes a bolt for fixing the corner brace 4 to the wall frames 8, 8.

(Problem to be solved by the invention) However, in the conventional mounting structure described above, the mounting procedure for the outer wall corner is as follows: tightening the bolts 9, 9, inserting the omega bolts 7, 7,
The holding plates 5, 5 must be attached and fixed to the omega bolts 7, 7 by tightening the nuts, which must be done in a certain order, and the work is very complicated and troublesome, and the degree of tightening of the nuts cannot be determined. This tends to vary depending on the builder, resulting in inconveniences such as not being able to achieve uniform construction accuracy.

In addition, the above series of installation work includes the exterior wall panel 6,
6 and the outer wall corner 1 between the joints 15, 15, and therefore a joint material or the like was required to cover the joints 15, 15.

(Means for Solving the Problems) In the exterior wall corner mounting structure of the present invention, a corner brace 4 made of lip angle steel is installed at the protruding corner 3 where two exterior wall panels 6, 6 meet on both lips. 4
While the opening between a and 4a is erected with the opening facing outward, a vertically long flat plate is bent at a substantially right angle across the entire length in the widthwise center of the plate, and the bent portion is attached to both of the outer walls. Corner part 1 fitted between panels 6, 6
a, bend the left and right edges of the corner portion 1a inward, and then fit the tip portions of the bent pieces 14, 14 into the lip portions 4a, 4a of the corner stud 4, respectively. Fitting recess 1
1 and 11, and the pieces on the free end sides of these fitting recesses 11 and 11 are bent.
contact portions 12 each curved in an arc shape bulging inward and abut against the inner surfaces of the lip portions 4a, 4a;
12 is formed, and the abutting portions 12, 12 of the outer wall corner 1 are forcibly fitted into the corner stud 4 from the opening, and the fitting recess is formed. 11,11
and the lip portions 4a, 4a are fitted, and the outer wall corner 1 is attached to the protruding corner portion 3.

(Operation) The operation of the present invention will be explained with reference to FIG. 2 showing one embodiment.

First, apply the abutting parts 12, 12 of the outer wall corner 1 to the lip parts 4a, 4a of the corner stud 4,
If the outer wall corner 1 is hit with a mallet or the like in this state, the bent pieces 14, 14 of the outer wall corner 1 will be pushed inward against their own elasticity.
As a result, the interval between the abutting parts 12, 12 narrows, and the abutting parts 12, 12 enter into the corner stud 4. At the same time, the fitting recess 1 of the outer wall corner 1 is
1, 11 and the lip portions 4a, 4a of the corner post 4
At the same time, the abutting portions 12, 12 abut against the inner surfaces of the lip portions 4a, 4a, thereby preventing the outer wall corner 1 from coming off the corner stud 4. In this way, since the exterior wall corner 1 can be attached by a simple operation such as hammering, conventionally, a gap is provided between the exterior wall corner 1 and the exterior wall panels 6, 6 for attaching the omega bolts for attaching the exterior wall corner. This eliminates the need for a joint material to close such gaps.

(Embodiment) Hereinafter, an embodiment of the present invention will be described with reference to the drawings with reference to FIGS. 2 and 3. In these figures, the same members, portions, and components as shown in FIG. 1 (showing a conventional example) are designated by the same reference numerals.

In Fig. 2, at the protruding corner 3 where the two outer wall panels 6, 6 meet, a corner post 4 made of lip angle steel is erected with the opening between the lip parts 4a, 4a facing outward. It is set up. Wall frames 8, 8 that support the outer wall panels 6, 6 are connected to each side surface (the upper and left side surfaces in the figure) of the corner post 4 erected in this manner by suspension bolts 9, 9. ing.

On the other hand, the outer wall corner 1 attached to the above-mentioned protruding corner part 3 is formed by bending a vertically long flat plate at a substantially right angle over the entire length in the longitudinal direction at the central part in the width direction. At the same time, the left and right side edges of this corner portion 1a are each bent inward, and a lip of the corner support post 4 is formed at the tip of each of the bent pieces 14, 14, respectively. The fitting recesses 11, 11 that fit with the parts 4a, 4a are bent, and the free end pieces of these fitting recesses 11, 11 are attached to the recess 1.
The contact portions 12, 12 are curved in an arc shape that bulges out into the inner surfaces of the lip portions 1, 11, respectively, and abut against the inner surfaces of the lip portions 4a, 4a. The corner portion 1a of the outer wall corner 1 is sized so that its left and right end portions are in contact with the side end portions of the outer wall panels 6, 6, respectively. In addition, the outer wall corner 1 has its contact portion 1 as shown in FIG.
The distance a between the edges of the corner studs 2 and 12 is made slightly narrower than the distance b between the lip portions 4a and 4a of the corner post 4, and the distance between the bottom surfaces inside the fitting recesses 11 and 11 is set to a corner width. Lip part 4 of support post 4
It is desirable that the distance b be slightly wider than the distance b between a and 4a. Further, it is preferable that the bending angles P, P of the bending pieces 14, 14 are each an acute angle larger than 45 degrees.

To attach the exterior wall corner 1 as described above to the protruding corner 3, first,
It is sufficient to simply place the abutting portions 12, 12 on the lip portions 4a, 4a of the corner stud 4 (see Fig. 3), and in this state hit the outer wall corner 1 with a mallet or the like. By doing so, the bent pieces 14, 14 of the outer wall corner 1 will be pushed inward against their own elastic force, and as a result, the interval between the abutting parts 12, 12 will narrow, and the abutting parts 12, 12 enters into the corner post 4. At the same time, outer wall corner 1
The fitting recesses 11, 11 and the lip portions 4a, 4a of the corner post 4 fit together, and the lip portion 4
The abutting portions 12, 12 abut against the inner surfaces of the a, 4a, thereby preventing the outer wall corner 1 from coming off the corner stud 4.

In this example, two exterior wall panels 6, 6 meet at the protruding corner 3, but the present invention is not limited to this. One is an exterior wall panel and the other is, for example, a sash frame, or both are sash frames. In either case, the outer wall corner 1 can be used.

(Effects of the invention) The exterior wall corner mounting structure according to the present invention has corner braces made of lip angle steel erected at the protruding corners, while fittings that fit with the lip portions of the corner braces are installed at the outer wall corners. Forming a recess and a contact portion that contacts the inner surface of the lip portion so that the fitting recess of the outer wall corner and the lip portion of the corner post are fitted together, and the contact portion is brought into contact with the inner surface of the lip portion. Because of this, external wall corners can be installed with a simple process such as simply hammering in. Not only does it eliminate the need for any parts to attach external wall corners to protruding corners, but it also makes it easy for the installer to install them. It is possible to obtain a certain level of construction accuracy and installation strength regardless of the location. Further, since the outer wall corners are provided with abutting portions that abut against the inner surfaces of the lip portions of the corner studs, the outer wall corners will not come off due to a slight external force. Furthermore, since no parts are required for attaching the outer wall corner to the protruding corner, the joint width between the outer wall corner and the outer wall panel can be eliminated. Therefore, members such as joint materials that were conventionally required are not only unnecessary, but also the appearance of the protruding corners can be improved. In addition, it is economical because the number of parts is much smaller than in the past.
