PURPOSE: To obtain high connection strength in the case a column is connected to horizontal members so as to cross therewith.

CONSTITUTION: A connection metal fixture for a structure has fixed pieces 32 fixed to the sides of a column 1 and vertical pieces 31 and 21 projected to the fixed pieces 32 approximately in vertical from the fixed pieces 32, the fixed pieces 32 are formed in a U-shape from a front view, and the vertical piece 31 is cut and raised in opposition to the column 1 from the end edges of holding pieces 32c held between opposite pieces 32b opposed to the fixed pieces 32 to form the connection metal fixture. Or, the vertical piece 21 projects a fixed piece 32a of a folded piece 21a of an auxiliary metal fixture having an L-shaped section provided with a fixed piece 22 fixed to the fixed piece 32a and the folding piece 21a folded approximately in vertical from the fixed piece 22 from a through groove 10 provided to the fixed piece 32a to form the connection metal fixture.
