<p>PROBLEM TO BE SOLVED: To provide a connecting structure for the end of a steel pipe and a roof substrate material, enabling the roof substrate material to be disposed in the position as close as possible to the downstream end side of a roof material. SOLUTION: A tie-in plate 3 is fixed to the indoor-side surface of a column. The tie-in plate 3 is provided with an upper chord 5 and a diagonal member 6, which constitute a trussed girder. The upper chord 5 is composed of a round steel pipe, and the tie-in plate 3 is inserted for welding into the end of the upper chord 5 so as to fix the upper chord 5 and the tie-in plate 3 together. A closing plate 8 is joined to the end surface of the upper chord 5 by welding. The closing plate 8 is formed in a length equal to or greater than the length necessary to close the end surface of the upper chord 5. A purlin 9 is mounted on the lengthened area, and a folded plate 11 is fixed on the purlin 9 through a tight frame 10.</p> |
