<P>PROBLEM TO BE SOLVED: To provide a T-bar connection structure of a system ceiling, which is free from the risk of deformation of a T-bar or a T-bar connection fitting when the ceiling is disassembled, and is reusable, and to provide the T-bar connection fitting for use in the T-bar connection structure. <P>SOLUTION: A main T-bar 1 and an orthogonal T-bar 2 have erect pieces 1a, 2a, and transverse pieces 1b, 2b extending on both sides of lower edges of the erect pieces, respectively, and both the T-bars are inverted T-shaped members so that a ceiling surface plate is mounted on the transverse pieces. Then an edge of the orthogonal T-bar 2 is connected to a side surface of the main T-bar 1 via the T-bar connection fitting 3. The T-bar connection fitting 3 is a bent plate product, and has a main T-bar connection piece 4 arranged along the side surface of the erect piece 1a of the main T-bar 1, and an orthogonal T-bar connection piece 5 arranged along a side surface of the orthogonal T-bar 2. The main T-bar connection piece 4 and the orthogonal T-bar connection piece 5 of the T-bar connection fitting 3 have dowels 6, 8 arranged thereon, for fitting into holes 11, 13 formed in the erect pieces 1a, 2a of the main T-bar 1 and the orthogonal T-bar 2, respectively. <P>COPYRIGHT: (C)2009,JPO&INPIT |
