<p><P>PROBLEM TO BE SOLVED: To not only inhibit joint opening, but also decrease the number of supporting members. <P>SOLUTION: Facing board members 170A, 170B, which are adjacent each other in the width direction, are stacked on the outer surfaces of lining board members 160A, 160B, which are adjacent each other in the width direction, in such a way that a longitudinal joint 176 formed between the edge 170L of the facing board member 170A and the edge 170R of the facing board member 170B is horizontally displaced from a longitudinal joint 166 formed between the edge 160L of the lining board member 160A and the edge 160R of the lining board member 160B. The edge 170L of the facing board member 170A and the edge 170R of the facing board member 170B are also fixed to a intermediate stud 120M by machine screws 173 respectively. The machine screw 173 penetrates through the edge 170L (or the edge 170R) in the width direction of the facing board member 170 and the edge 160R in the width direction of the lining board member 160, and is fastened to the intermediate stud 120M. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
