止め具。[Claims] 1. After placing reinforced concrete for the floor and columns on the lower floor, and with the formwork for pouring the beams on the upper floor installed, The upper beam reinforcement and beam lower reinforcement of the reinforcing bars that make up the floor beams are combined with the column reinforcement of the column, and the beam stirrup reinforcement, abdominal reinforcement, and width stop reinforcement are used in the area other than the column reinforcement to reinforcing the beam. After forming a column hoop reinforcement at the beam intersection on the outer periphery of the column reinforcement, when pouring the beam of the upper floor on the formwork, the reinforcement structure of the beam is formed using the mold. The beam lower reinforcement is held by the beam lower reinforcement supporter which is bridged in the beam forming recess on the frame, and the beam upper reinforcement is held by a horse installed on the formwork, and the beam intersection column is held. With the hoop reinforcement arranged around the outer periphery of the column reinforcement, the beam lower reinforcement support and the horse are removed, the reinforcement structure of the beam is dropped into the recess of the formwork, and concrete is poured. In a reinforced concrete construction method in which a beam for the upper floor is formed and the upper floors are constructed in the same way, the lower beam reinforcement is arranged, and before the upper reinforcement is arranged, the reinforcement is placed around the column reinforcement at a predetermined interval. When a plurality of the beam intersection column hoop reinforcements are arranged and interposed, and the beam reinforcement is reinforced using the horse, the uppermost hoop reinforcement of the beam intersection column hoop reinforcement is connected to the beam intersection section. A reinforced concrete construction method characterized in that the reinforcement structure of the beam is connected to the upper reinforcement, the reinforcement structure of the beam is dropped into the recess of the formwork, and the beam intersection column hoop reinforcement is arranged at a predetermined interval around the outer periphery of the column reinforcement. . 2. After pouring reinforced concrete for the floor and columns on the lower floor, formwork for pouring the beams on the upper floor is installed, and the beams on the upper floor to be connected to the columns are constructed. The beam upper reinforcement and beam lower reinforcement of the reinforcing bars are combined with the column reinforcement of the column, and the beam stirrup reinforcement, abdominal reinforcement, and width stop reinforcement are used in the part excluding the column reinforcement to form the reinforcement structure of the beam. After forming column hoop reinforcements at beam intersections on the outer periphery of the column reinforcements, when placing the upper floor beams on the formwork, the formation of the reinforcing bar structure of the beams is performed using the beam formation on the formwork. The beam lower reinforcement is held by the beam lower reinforcement support block bridged in the recess, and the beam upper reinforcement is held by a horse installed on the formwork, and the column hoop reinforcement at the beam intersection is connected to the column reinforcement. The beam bottom support block and the horse are removed, the reinforcing bar structure of the beam is dropped into the recess of the formwork, and concrete is poured to form the upper floor beam. In a reinforced concrete construction method in which the upper floors are constructed in the same way, the beam upper reinforcement and the beam lower reinforcement are supported on the formwork by the beam lower reinforcement support and the horse. and a plurality of engaging bodies each having a space for engaging the beam intersection column hoop reinforcement and having an opening that elastically engages with the beam intersection column hoop reinforcement installed between the lower reinforcements; A beam intersection column hoop reinforcement width stopper comprising a flexible spacing piece that connects each engaging body and maintains the beam intersection column hoop reinforcements at a predetermined interval. 3. The beam intersection column hoop reinforcement width stopper according to claim 2, wherein the engaging body and the spacing piece are integrally molded.
