FLOOR SLAB REPLACING STRUCTURE AND FLOOR SLAB REPLACING METHOD
To provide a floor slab replacing structure and a floor slab replacing method that suppress opening at a construction joint part of a replacing part constructed on an existing floor slab to prevent it from becoming a structural weak point.SOLUTION: A floor slab replacing structure 1 includes: a preceding replacing layer 3 formed on an upper surface of an existing floor slab 2; a following replacing layer 4 formed on the upper surface of the existing floor slab 2 in a state where an end surface 41 is abutted to an end surface 31 of the preceding replacing layer 3; and a reinforcement material 5 provided across the preceding replacing layer 3 and the following replacing layer 4. On the end surface 31 of the preceding replacing layer 3, a step with a lower side protruding toward the following replacing layer 4 side is formed. The end surface 41 of the following replacing layer 4 has an upper side protruding toward the preceding replacing layer 3 side to engage with the step formed on the end surface 31 of the preceding replacing layer 3. Furthermore, the reinforcement material 5 is a lattice-shaped face material parallel to the upper surface of the existing floor slab 2.SELECTED DRAWING: Figure 1
【課題】既設床版上に施工した打替部の施工目地部における目開きを抑制し、構造上の弱点となることを防ぐことを可能とした、床版打替構造および床版上打替工法を提案する。【解決手段】既設床版２の上面に形成された先行打替層３と、端面４１を先行打替層３の端面３１と突き合せた状態で既設床版２の上面に形成された後行打替層４と、先行打替層３と後行打替層４とに跨って設けられた補強材５とを備える床版打替構造１。先行打替層３の端面３１には、下側が後行打替層４側に突出する段差が形成されている。また、後行打替層４の端面４１は、先行打替層３の端面３１に形成された段差と係合するように上側が先行打替層３側に突出している。さらに、補強材５は、既設床版２の上面と平行な格子状の面材である。【選択図】図１
