Also, a joint fitting 5b is coupled to the fittings 5a for keeping the projections thereof close to each other. The horizontal piece 5g of the fitting 5a is positioned between the support fitting 4 connected to a hanger bolt 3 and the fitting 5b, and the fittings 5b and 4 are tightened with a connection bolt 40.
