Claims

[Scope of Claim for Utility Model Registration] (1) It is a precast beam with stirrups and bottom reinforcements buried, which is installed between the columns of a reinforced concrete structure and forms part of the girder, and the main body consists of the bottom plate and side plates. The upper part of the stirrup protrudes from the upper end of the side plate, the ends of the lower reinforcement protrude from both ends, and the hollow part between the side plates has shafts at required intervals in the length direction of the main body. A precast concrete beam characterized by having ribs protruding in a direction perpendicular to the direction and having both side plates connected. (2) It is a precast beam that is installed between the columns of a reinforced concrete structure and forms part of the girder, with the stirrup and bottom reinforcement buried in it. A precast concrete beam having a cross-sectional shape, with the upper part of the stirrup protruding from the upper end of the main body, and the ends of the lower end reinforcements protruding from both ends, the two of which are tied together to form a girder.
