Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outer wall material for a corner of a building which is generally called a homogeneous corner, a homogeneous corner, or a common corner, etc. More specifically, the present invention relates to a corner material designed in a tile style or the like and a method of manufacturing the same.

[0002]

2. Description of the Related Art A conventional corner material is formed so that the length in the vertical direction is substantially the same as the length in the short direction of one outer wall material called a horizontal siding plate. The plurality of protruding corner members formed as described above are sandwiched between joining plates called hat-type joiners or vertical jointers, and are sequentially piled up and constructed.

[0003] Such a corner material is manufactured by the following steps. First, the horizontal pasting siding plate is cut along a cutting line parallel to the short direction to form a pair of protruding corner divided bodies and bonded to the inclined end portions of the protruding corner divided bodies. The agent is applied to form an L-shaped corner material. Next, the triangular front corner portion of the bonding portion is chamfered, and the same color paint is applied to the chamfered portion. Further, the excess adhesive that has protruded into the inner portion opposite to the chamfered portion is scraped off, thereby completing the production of one corner material.

[0004]

In the conventional corner material as described above, since a plurality of slightly corner-formed corner materials are manufactured, the time required for the production is required to be somewhat longer. In addition, there is a problem that it is difficult to make the accuracy, dimensions and the like of the product uniform. In addition, not only are production costs and packing costs for manufacturing such corner materials high, but also because the corner materials are piled up sequentially at the construction site, construction is performed by inexperienced craftsmen. Then, an error occurs in the setting position of each corner material, or the corner material cannot be set to a regular position, so that the side joint of the corner material and the side joint of the horizontal pasting siding plate are linear. There is a problem that the construction cost may be high or the time may be wasted due to the modification. In addition, since a joining plate such as a hat-type joiner is used, the corner material is inclined by the thickness of the joining plate, which has the disadvantage that the wall surface is not finished beautifully. Therefore, there is a problem that the bonding portion of the corner material is easily broken at the time of construction. Further, in the corner material manufacturing step, an extra step of scraping off excess adhesive inside the portion where the corner corner divided bodies are bonded is required.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and it is possible to manufacture a corner material at low cost, and to quickly and appropriately form a corner material regardless of the technical skills of construction workers. It is an object of the present invention to provide a corner material for an outer wall and a method for manufacturing the same, in which a portion can be constructed and the strength of the corner material can be increased.
