Therefore, the builder fixes the partition wall by fixing the first interior board 1c forming one wall surface and then fixing the second interior board 1d forming the other wall surface via the locking metal fitting 20. Can be completed. Further, the locking metal fitting 20 includes a pair of upper and lower enlarged heads 21 and contracted portions 22 interconnected with each other via connecting plates 40 and 42, or a plate body 41 functioning as a reinforcing rib. Since the first and second inner boards 1c and 1d interconnected by the locking metal fittings 20 have relatively high rigidity, they form a hollow wall that is structurally and strength stable.

When the partition wall thus constructed is disassembled, an external force exceeding a certain limit is applied to the interior board 1 in the direction in which the interior boards 1c and 1d are separated from each other.
When added to c or the interior board 1d, the enlarged curved edge 25 of the enlarged head 21 pushes and spreads the left and right engaging portions 8 and passes through the opening 9, and the locking metal fitting 20 is the hollow portion of the reinforcing member 2. Pulled out of. Thus, the enlarged head 21 and the reinforcing member 2 are separated from each other, and the interior boards 1c and 1d are disassembled. Therefore, the interior boards 1c and 1d attached via the attachment structure of this example are separated from each other by a certain amount of external force, as in the first to third embodiments. , Can be dismantled and removed relatively easily.
