CORE MATERIAL AND UPPER SIDE CORE MATERIAL REMOVING METHOD
To provide a simplified connection structure of an upper side core material to be removed with a lower side core material to be left.SOLUTION: A core material 4 for an earth retaining wall 1 has an upper side core material 11, a lower side core material 12, a splice plate 15, upper part fixing means 14b fixing the upper part of the splice plate 15 and an outer face of the upper side core material 11, and lower part fixing means 14a fixing the lower part of the splice plate 15 and an outer face of the lower side core material 12. The splice plate 15 has a first cutout part 21 formed on the right side of the lower part of the splice plate 15 and extended from an edge part 15a of the splice plate 15, and a first through-hole 22 formed on the left side of the lower part of the splice plate 15. The lower side core material 12 has a second through-hole 23 formed on the right side of the outer face of the lower side core material 12, and a second cutout part 24 formed on the left side of the outer face of the lower side core material 12 and extended from an edge part 12ba of the outer face of the lower side core material 12. The lower part fixing means 14a includes a first bolt 16 penetrating through the first cutout part 21 and the second through-hole 23 and a second bolt 17 penetrating through the first through-hole 22 and the second cutout part 24.SELECTED DRAWING: Figure 2
【課題】撤去される上側芯材と、残置される下側芯材との連結構造を簡素化する。【解決手段】土留め壁１用の芯材４は、上側芯材１１と、下側芯材１２と、添接板１５と、添接板１５の上部と上側芯材１１の外面とを固定する上部固定手段１４ｂと、添接板１５の下部と下側芯材１２の外面とを固定する下部固定手段１４ａとを備える。添接板１５は、添接板１５の下部の右側に形成されて添接板１５の縁部１５ａから延びる第１切欠き部２１と、添接板１５の下部の左側に形成された第１貫通孔２２とを有する。下側芯材１２は、下側芯材１２の外面の右側に形成された第２貫通孔２３と、下側芯材１２の外面の左側に形成されて下側芯材１２の外面の縁部１２ｂａから延びる第２切欠き部２４とを有する。下部固定手段１４ａは、第１切欠き部２１及び第２貫通孔２３を貫通する第１ボルト１６と、第１貫通孔２２及び第２切欠き部２４を貫通する第２ボルト１７とを含む。【選択図】図２
