The reinforcement of the column is exposed in the open side part of the hollow part, and a beam support bracket is provided continuously on the lower bottom surface of the hollow part,
Cut the protruding end of the beam end surface of the beam bottom reinforcement in beam C, and
When the C-beam is mounted on the beam support bracket, the protruding end of the beam lower end reinforcement of the PC beam is prevented from interfering with the tie reinforcement of the side opening in the hollow part of the PC column. Thereafter, a fixing bar passing through the same band reinforcement was placed in the hollow part, and the fixing bar was welded to the lower end bar of the PC beam, thereby making the PC beam
The beam bottom reinforcement of the beam is set in the hollow part of the PC column, and in this state, concrete is poured into the hollow part, thereby joining the PC beam to the column capital side surface of the PC column via the hollow part. On the other hand, in conjunction with integrally joining the PC column to the column head via the concrete poured in the upper panel zone, it is possible to use the PC construction method instead of using the cast-in-place concrete construction method to construct PC beams with different levels. This allows for installation on PC columns, which simplifies on-site construction, saves labor and shortens the process, and reduces construction costs.
