PC MEMBER AND JOINING METHOD THEREFOR

PROBLEM TO BE SOLVED: To improve workability and save time and labor in joining by bringing PC members close to each other by using a jointing method which is not necessary to protrude a reinforcing bar from the PC member in joining of the PC members. SOLUTION: Coupling tubes 13, 23 connected with main reinforcements 11, 12, 21, 22 and opened to joining surfaces and further having injection holes 15, 25 for filler are embedded in the joining parts. A joint rod 16 is inserted into the coupling tube 15 of one PC member 10. The respective coupling tubes 13, 23 are opposed to each other and the joining surfaces are brought close to each other. The filler 30 is injected into the coupling tube 13 of the PC member 10 through the injection hole 15, so that the joint rod 16 is advanced and is moved in the coupling tube 23 of the other PC member 20. Thereafter, the filler 30 is injected into the coupling tube 23 of the other PC tube 20 through the injection hole 25, and the respective coupling tubes 13, 23 and a space between the joining surfaces are filled with the filler 30.
