BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an interior cloth corner base material to be attached to a corner of an interior surface such as an indoor wall surface to which an interior cloth is attached, and to a method of finishing the interior surface.

[0002]

BACKGROUND ART Conventionally, in order to finish an interior surface of a ceiling or a wall, an interior cloth pasted on the interior surface has been used. Further, at a boundary portion between the ceiling and the wall, a surrounding edge, a bottom joint, and the like are provided in order to distinguish between the ceiling and the wall.

[0003] Of these, the bottom joint is a groove-like parting provided along the boundary between the ceiling and the wall. At the edge of the groove of the bottom joint, a corner portion serving as a protruding corner is formed. The interior wall cloth on the wall side crosses the corner and reaches the inside of the groove, and abuts with the interior ceiling cloth on the ceiling side inside the groove. Here, a bottom jointer is provided at the corner as a base material of the interior wall cloth on the wall side (see Japanese Patent Application No. 10-256847).

FIGS. 7 and 8 show an example of a conventional bottom jointer. In the figure, at the boundary between the ceiling 100 and the wall 101, a bottom joint joiner 103 is provided along the upper edge of the wall 101 to form a bottom joint 102 extending in a groove shape along these boundary lines. I have.
A corner 104 is formed on the upper edge of the wall 101,
When the wall 101 having the corners 104 is finished with the interior wall cloth 105, the bottom jointer 103 also plays a role in shaping the corners 104. Here, the bottom jointer 103 is connected to the main body 10, one end of which is in contact with the ceiling.
3A, a cover 103B having an L-shaped cross section protruding from the other end of the main body 103A, and a positioning protrusion 103C protruding from an intermediate portion on the back surface of the main body 103A and detachable from the main body 103A. . The provision of the bottom jointer 103 allows the interior ceiling cloth 106 and the interior wall cloth 105 to be attached to the surface of the bottom joint joiner 103 as well.

At this time, the bottom jointer 103 and the wall 10
Putty 107 is placed on the stepped portion at the boundary with the interior surface of No. 1 to eliminate the step formed at the boundary,
The putty 107 is made with a trowel or the like.
