PURPOSE: To improve the work efficiency by installing a sliding member on the lower surface of a large beam to be slid in the horizontal direction on a sliding railway fixed on a wall part.
CONSTITUTION: A beam 3 erected in the cross-direction of a rool is previously formed by a precast, and the beam 3 is lifted up along the sides of confronting wall parts 5 of a building 2 up to the height of construction position. The lifted-up beam 3 is slid in the longitudinal direction of the wall part 5 to be set in the construction position. Subsequently, the pre-stress is implemented on the whole of the beams 3 in the cross direction to be united into one body, and concrete is placed and filled in the beam 3 to construct a roof 1. Accordingly, it is possible to improve the efficiency of construction of a beam and safety of a work.
