PROBLEM TO BE SOLVED: To provide an internal-corner-section mounting structure which enables ends of a pair of boards to be accurately joined together leaving no space between them gap, in the state of being supported on a column, at the internal corner section where a pair of indoor wall surfaces crosses each other at a right angle, by using a simple constitution.;SOLUTION: A T-shaped cross-section board substrate metal fitting 10, which is formed of a tie plate-like thin iron plate 22 thin enough to enable the screwing and penetration of a screw 13 and which is composed of a base plate part 14 and a protrusive plate part 15 perpendicularly elongated from a central part of the base plate part 14, is arranged by positioning a joining part 16 along a corner part of the column 12; a backside of one part 18 of the base plate part 14 is brought into close contact with the column 12; and the screw 13 is screwed so that the other part 19 of the base plate part 14 and the protrusive plate part 15 can be protruded along the direction of each of the wall surfaces 21a and 21b. The end of one board 11a is fixed along the protrusive plate part 15, and the end of the other board 11b is fixed along the other part 19 of the base plate part 14.;COPYRIGHT: (C)2005,JPO&NCIPI
