CONSTRUCTION METHOD OF CONCRETE STRUCTURE AND FORM STRUCTURE
To provide a construction method of a concrete structure capable of constructing a new concrete structure even when a distance between an existing structure and a newly-installed concrete structure are narrow, and to provide a form structure of the concrete structure.SOLUTION: An outside form temporary-installation step includes: a lower plate part temporary-installation step of temporarily installing a lower plate part 51 covering a gap between a projecting part 133 and an outside face 332a opposed closely to the projecting part 133 from below from an empty part 14; an outside pressing part temporary-installation step of temporarily installing an outside pressing part 53 along the outside face 332a on an upper side of the lower plate part 51 after the lower plate part temporary-installation step; and a sand filling step of filling sand 54 between the outside pressing part 53 and the projecting part 133 on an upper side of the lower plate part 51. An outside form removing step includes: a sand removing step of removing the lower plate part 51, dropping the sand 54 into the empty part 14, and then removing the sand from between the outside pressing part 53 and the projecting part 133; and an outside pressing part removing step of removing the outside pressing part 53 from between a floating foundation 3 and a floor slab 1 constructed.SELECTED DRAWING: Figure 2
【課題】既設構造物と新設のコンクリート構造物との間が狭隘な場合でも、新設のコンクリート構造物を構築することができるコンクリート構造物の構築方法および型枠構造を提供する。【解決手段】外側型枠仮設工程は、突出部１３３と近接して対向する外側面３３２ａと突出部１３３との隙間を下側から覆う下板部５１を空部１４から仮設する下板部仮設工程と、下板部仮設工程の後に、下板部５１の上側において外側面３３２ａに沿って外側押さえ部５３を仮設する外側押さえ部仮設工程と、下板部５１の上側において外側押さえ部５３と突出部１３３との間に砂５４を充填する砂充填工程と、を有し、外側型枠撤去工程は、下板部５１を撤去し、砂５４を空部１４に落下させて外側押さえ部５３と突出部１３３との間から撤去する砂撤去工程と、構築された浮基礎３と床スラブ１との間から外側押さえ部５３を撤去する外側押さえ部撤去工程と、を有する。【選択図】図２
