PROBLEM TO BE SOLVED: To provide an attic structure easy in construction, and easy in disassembling and reuse of a member. SOLUTION: A second floor part for placing an attic space is formed by sticking structural plywood 5 having the sufficient thickness in advance on a tie beam 3. An angle shape frame 6 for supporting a roof is formed in an inverse V shape by welding a box-shaped lightweight steel frame and has a flat beam part 6a horizontally extending inward from its both ends (an arm part). This flat beam part is fixed to the tie beam 3 just below by a bolt 9. COPYRIGHT: (C)2006,JPO&NCIPI
