<P>PROBLEM TO BE SOLVED: To provide an opening internal corner backing material which allows a vertical external corner and lateral external corner to get a curved and chamfered shape and enables a good design to be kept in an internal corner of a wall face opening even when time has elapsed since building construction. <P>SOLUTION: The opening internal corner backing material 200 formed into L-shape is disposed in the internal corner between a column matrix 10 and a beam matrix 20 for forming a wall face opening of a building. A vertical backing main body 210 forming the one end side of L-shape of the opening internal backing material 200 is disposed along the internal corner side portion in the corner part of the column matrix 10, and the vertical external of the wall face opening formed into a chamfered curved shape is continuously disposed with regard to a linear vertical external backing material 110. A lateral backing main body part 220 forming the other end side with L-shape of the opening internal backing material 200 is disposed along the internal side portion in the corner part of the beam matrix 20, and the lateral external corner of the wall face opening formed into a chamfered curved shape and integrally formed with the vertical backing main body part 210 is continuously disposed with respect to a linear lateral external backing material 120. <P>COPYRIGHT: (C)2012,JPO&INPIT |
