PROBLEM TO BE SOLVED: To provide a panel structure for a steel house, which prevents degradation in flatness of a panel due to a bump of a screw head. SOLUTION: Channels are each formed by bending a thin steel plate to shape a web and flanges continuously extending from both edges of the same. One of the channels 1 thus formed is arranged at a predetermined location, and the other channel 2 is inserted into the one channel 1 via its end to form a superposed portion 28 to which a drilling screw 29 is driven, whereby the head 30 of the drilling screw 29 driven thereto is protruded from the flange of the other channel. Therefore protrusions 39 are formed on the flange 52 surface of the other channel 2 so as to have almost the same height as that of the head 30 of the drilling screw 29. COPYRIGHT: (C)2006,JPO&NCIPI
