Patent attributes
A structure enables free and reasonable designing of a cross section of an end of a steel beam in accordance with bending stress and a housed state of a PC steel, thereby providing an economic and reasonable building as a whole. A beam end block includes end plates and an anchor plate. The end plates are fixed at an end surface of an H-section steel in a direction substantially perpendicular to the longitudinal direction of the beam. The anchor plate is fixed to the H-section steel separately from the end plates, on a side opposite to a column, in a direction substantially perpendicular to the longitudinal direction of the beam. An end of the steel beam has an upper part and a lower part. The upper part protrudes toward the column more than the lower part and is mounted on a cogging. The beam end block has a height dimension larger than the height dimension of the H-section steel and has a lower end that is disposed at substantially the same height as a lower end of a side surface of the cogging facing the lower part of the end of the steel beam.
