JOINT STRUCTURE OF PRECAST CONCRETE MEMBER

摘要

<P>PROBLEM TO BE SOLVED: To reduce construction cost by making a welding operation on site unnecessary and reducing the amount of used grout material; to improve external appearance by making the width of a joint portion small. Ž<P>SOLUTION: Embedded members 5 for anchorage respectively jointed to reinforcing bars 4 disposed in plural stages in the vertical direction are embedded in a joint end face of one divided precast cylinder body 2. The embedded member 5 for anchorage is formed with pocket-shaped notched grooves 6 whose opening faces the outside, and formed with vertical grooves 7 having a same shape as the notched groove 6 and vertically continued by forming the notched grooves in concrete along the vertical direction. Reinforcing bars 8 disposed in plural stages in the vertical direction are installed in a joint end face of the other divided precast cylinder body 3 so as to project up to the outside, and anchorage members 9 fitted to the pocket-shaped notched grooves 6 are fixed to the tip end of the reinforcing bars 8 respectively.
