By vertically installing the small beams as one unit, the construction period is shortened compared to the conventional structure in which the small beams and floorboards are separated.Also, since the entire cross section of the small beams works effectively, problems such as deflection and cracks are avoided. Furthermore, since the upper end surface of the small beam protrudes outward from one side edge of the floorboard, this protrusion can be used to connect the adjacent P.
The connecting end of the C floor plate can be mounted on top.

れるものである。In addition, the cost reinforcement is surrounded between the upper end beam reinforcement buried in one side edge of the PC floor plate and the lower end beam reinforcement buried in the lower part of the PC floor plate, and thus the reinforcing bars of the minor beam are pre-attached to the floor plate with the minor beam. By arranging the reinforcing bars at the time of manufacturing, the assembly work of reinforcing bars for the small beams on site is omitted, and furthermore, each part of the upper end beam part and the reinforcing bars are exposed to a part of the footer provided on the end surface of the PC floorboard. Therefore, the joint concrete poured between the same PC floor plate and the adjacent PC floor plate is integrated with the floor plate end face of the floor plate with small beams and the PC small beams via the cotter and the exposed reinforcing bars in the cotter. This ensures that adjacent floorboards are joined together.
