DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing an outer wall corner member for efficiently manufacturing an outer wall corner member such as an outer corner member and an inner corner member used at the outer wall corner of a building. .

[0002]

2. Description of the Related Art In recent years, there has been a remarkable increase in demand for ceramic exterior wallboards which are excellent in design of surface pattern and excellent in workability as exterior wallboards for houses. As shown in FIG. 7, the outer wall constructed using the ceramic-type outer wall plate uses an outer corner member 12 having the same pattern as the outer wall plate 11 in the outer wall corner portion 10. It is fixed to a pillar 14 with a nail 15 or the like via a base material 13.

[0003] Generally, the ceramic outer wall panel 11 is often formed by pressing an uneven pattern on the surface in order to enhance the design, but since the protruding corner member 12 has an L-shaped cross section, it is necessary to use an uneven pattern. It is extremely difficult to integrally mold. For this reason, the protruding corner member 12 of the concavo-convex pattern is formed by cutting one end surface of each of two strip-shaped plate members into a slope of slightly less than 45 ° and bonding both slopes with an adhesive to integrate the two plate members. Many products are manufactured by manufacturing.

[0004]

As described above, in the case of manufacturing an outer wall corner member such as an outgoing corner member and an ingoing corner member by bonding two plate members with an adhesive, the solidification of the adhesive takes place until the adhesive is solidified. , About 10 to 15 hours, the outer wall corner member is placed on a pedestal having a predetermined angle, and
It is necessary to keep it for about 0 to 15 hours. For this reason, the manufacturing efficiency of the outer wall corner member is poor, and it is not possible to quickly respond to the urgent order of the customer, which often causes trouble to the customer. In addition, a space is required in the factory where the outer wall corner members are allowed to stand until the adhesive is solidified, which is contrary to the demand for space saving of the work area in the factory.

[0005] The present invention has been made in view of such circumstances, and an object thereof is to substantially reduce the time required for bonding the outer wall corner members, and to quickly respond to an urgent customer order. It is an object of the present invention to provide a method of manufacturing an outer wall corner member that can cope with the problem, save space in a work area in a factory, and can automate or semi-automate the manufacturing process of the outer wall corner member.

However, an inside corner member in which the relationship between the front and back of the corner member 20 is reversed may be manufactured. In the case of a corner member, when cutting a strip-shaped plate obliquely, in contrast to the case of a corner member, an oblique cut is performed so that the front surface is narrower than the back surface, and the subsequent steps are performed. What is necessary is just to manufacture in the same way as the case of a corner member.

In addition, the present invention is not limited to the outer corner member and the inner corner member, but can be applied to a case where a polygonal outer wall corner member such as a hexagonal prism is formed. By setting the inclination angle of the placing member 36 and the inclination angle of the triangular reference base 47, the outer wall corner member having an angle other than less than 90 ° may be formed.
