JOINING STRUCTURE AND JOINING METHOD OF PRECAST MEMBERS
To halve the number of grout flowing holes in precast members, reduce the labor required to form them, and improve the appearance of the precast member surface due to the grout flowing holes.SOLUTION: A grout injection channel 25 is provided in a first precast member 10 or a second precast member 20, which leads from the outside to a joint space 2. A plurality of sleeves 4 have one end face opening into the joint space 2 and a grout flowing port 5 on the cylinder wall near the other end. One grout flowing hole 15 is formed in the first precast member 10 for each sleeve 4, opening outward from the grout flowing port 5 of each sleeve 4. The grout injection channel 25, the joint space 2, the interior of the sleeve 4, the grout flowing port 5 and the grout flowing hole 15 are continuously filled with a grout 3.SELECTED DRAWING: Figure 6
【課題】プレキャスト部材に形成するグラウト流通穴の数を半減させ、その形成の手間を低減するとともに、プレキャスト部材の表面のグラウト流通穴による見栄えの悪化を改善する。【解決手段】第１プレキャスト部材１０又は第２プレキャスト部材２０に、外部から目地空間２へ通じるグラウト注入路２５が設けられ、複数のスリーブ４は、一端面が目地空間２に開口し、他端付近の筒壁にグラウト流通口５が形成されたものであり、第１プレキャスト部材１０に、各スリーブ４のグラウト流通口５から外部へ開口するグラウト流通穴１５が、各スリーブ４について１つずつ形成され、グラウト注入路２５、目地空間２、スリーブ４の内部、グラウト流通口５及びグラウト流通穴１５に、グラウト３が連続して充填されている。【選択図】図６
