Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a projecting corner portion construction structure in which a projecting corner column is arranged in a projecting corner portion of a building, and a construction method thereof.

[0002]

2. Description of the Related Art Conventionally, as a projecting corner column used in a projecting corner construction structure for a projecting corner of a building, as shown in FIG. 21, two plate pieces 91 on the left and right are joined so as to be substantially perpendicular to each other. There is a projecting corner post 9 formed. The projecting corner post 9 is manufactured, for example, as follows.

First, as shown in FIG. 17, a plate member 910 such as a ceramic plate member is cut and a plate piece 91 is cut into an appropriate size. Then, as shown in FIG. 18, one side end portion 911 of the plate piece 91 is cut off obliquely to form a cut surface 9 at an angle of about 45 ° with respect to the front side surface 912 and the back side surface 913.
14 is formed.

Next, as shown in FIGS. 19 and 20, 2
Abutting the cut surfaces 914 of the plate pieces 91,
The two plate pieces 91 are joined so that the front side surfaces 912 thereof are substantially right angles. At this time, the cut surface 914 of the two plate pieces 91 is
An adhesive 92 is interposed between them. As a result, the two plate pieces 91 are bonded. In addition, the above two plate pieces 91
A tacker 94 is driven into the joint portion 93 to secure the joint strength. Next, as shown in FIG. 21, the outer corner portion 931 of the joint portion 93 is chamfered and cut, and the outer corner portion 931 is cut.
The chipping of No. 1 is prevented and the appearance design is improved.

[0005]

However, as described above, in the projecting corner post 9 used in the conventional projecting corner construction structure, the two plate pieces 91 are bonded using the adhesive 92 as described above. for that reason,
The adhesive 92 needs to be dried, which takes time to manufacture. In addition, the butt angle of two plate pieces 91 (for example, 90
It is necessary to have a holding jig for drying while holding (°).

Further, the adhesive 92 may protrude from the joint portion 93, which may deteriorate the appearance and design of the projected corner column 9. Therefore, in this case, it is necessary to scrape off the protruding adhesive 92. Further, as described above, the tacker 94 is struck on the joint portion 93 or the joint portion 9 is pressed.
It is also necessary to chamfer the outer corner portion 931 of No. 3. Then, it is necessary to repair the chamfered surface later.

Further, when a pattern pattern is formed on the front side surface 912 of the plate piece 91 and the pattern pattern shifts at the joint portion 93, an uncomfortable feeling is caused and the appearance and design of the projected corner post 9 is deteriorated. It may decrease. In addition, therefore, when joining the left and right plate pieces 91, it is necessary to carefully perform alignment so that the pattern patterns of the left and right plate pieces 91 do not shift. As described above, the projecting corner post 9 is not necessarily easy to manufacture, and as a result, it is difficult to obtain the projecting corner portion construction structure at low cost. In addition, when the projecting corner column 9 is constructed on the projecting corner,
The image of the right-angled corner remains, and it is difficult to obtain a soft feeling.

The present invention has been made in view of the above conventional problems, and it is easy to manufacture the projecting corner column to be used, easy to construct, inexpensive, and a projecting corner portion construction structure and a projecting appearance. It is intended to provide a corner construction method.

In addition, for example, a bond breaker may be attached to the front surface of the vertical joint protrusion, and an appropriate amount of the sealing material may be filled thereover (the gap between the small corner plate and the outer wall plate). Yes (see Figure 1).

Further, it is preferable that a ventilation layer is formed between the small corner plate and the fixed plate portion of the mounting plate (claim 5). In this case, it is possible to secure the air permeability of the rear side of the small corner plate and prevent the dew condensation.

Further, at the lower end of the projecting corner pillar, a projecting corner base drainer is disposed, and the projecting corner base drainer is a back plate portion fixed to the mounting plate and the back plate portion. And a draining plate portion that bends forward and downward at a lower portion, and the draining plate portion has wing portions that bend obliquely backward at the left and right ends thereof, and the wing portion is disposed below the outer wall plate. It is preferable to form an overlapping portion with the installed outer wall base drainer (claim 6). In this case, the rainwater that has flowed down to the base of the building along the projecting corner pillar can be discharged forward. Therefore, it is possible to reliably prevent the intrusion of rainwater from the base portion, and to obtain a durable corner construction structure with excellent durability. Further, since the wing portion forms a portion overlapping with the outer wall base drainer, it is possible to reliably prevent rainwater from entering.

Further, the draining corner base drainer is formed by forming a mounting portion which is bent forward on the back plate portion above the draining plate portion, and the mounting corner starter metal fitting is formed on the mounting portion. It is preferable that the lower end portion of the abutting portion abut (claim 7). In this case, the protruding corner starter fitting can be easily arranged at an accurate position, and the small protruding corner plate at the bottom can be easily arranged at an accurate position.

Next, in the second invention (claim 8), the fifth step is after the first step and is the sixth step.
It may be performed at any stage before the process. For example,
The fifth step may be performed after the first step, and then the second step may be performed.
