PROBLEM TO BE SOLVED: To increase the strength of a joint part by adopting novel structures of loop reinforcements and a steel plate installed therebetween in a joint structure of precast concrete floor plates. SOLUTION: In this joint structure of the floor plates, the end faces 10 of the floor plates 1 are positioned close to each other, and the loop reinforcements 11 are opposed to each other and alternately moved forward. The steel plates 3 are disposed on the inside of the loop reinforcements in opposed direction and in the lateral direction of the floor plate, and filling concrete 4 is deposited to form adjacent floor plates integrally with each other. The corner parts 11a of the loop reinforcements are formed in a generally right-angled channel shape by a hot bending. Also, the allocation of the steel plates is performed by continuously disposing the plurality sheets of steel plates, and the steel plates are disposed so as to abut on the insides of vertical reinforcements 11c connecting the corner parts of the loop reinforcements and on a side where a tension is applied thereto. In addition, notches 30 provided at the lower end edges of the steel plates are fitted to lateral reinforcements 11b receiving the tension of the loop reinforcements. COPYRIGHT: (C)2003,JPO
