To provide a construction method for a floating type foundation which can efficiently manufacture a floating type foundation made of concrete, and a trestle which is used in the construction method for the floating type foundation.SOLUTION: A construction method for a floating type foundation includes: a manufacturing step of manufacturing divided bodies on a trestle 4; an arrangement step of arranging the plurality of divided bodies side by side, and inserting a tendon into the plurality of divided bodies; and a tensioning step of introducing prestress to the plurality of divided bodies through the tendon and forming a floating type foundation. The trestle 4 includes: a manufacturing board 43 on which the divided bodies are mounted; a trestle main girder 41 for supporting the manufacturing board 43; a support member 42 for supporting the trestle main girder; and an edge cutting material 6 which is interposed between the divided bodies and the manufacturing board 43. The edge cutting material 6 can reduce a resistance force generated between the trestle 4 and the divided bodies when a horizontal force is made to act on the divided bodies.SELECTED DRAWING: Figure 5
【課題】コンクリート製の浮体式基礎を効率的に製作できる、浮体式基礎の施工方法と、この浮体式基礎の施工方法に使用する架台を提案する。【解決手段】架台4の上で分割体を製作する製作工程と、複数の分割体を並設するとともに複数の分割体に緊張材を挿通する配置工程と、緊張材を介して複数の分割体にプレストレスを導入して浮体式基礎を形成する緊張工程とを備える浮体式基礎の施工方法。架台4は、分割体が載置される製作板43と、製作板43を支持する架台主桁41と、架台主桁を支持する支持部材42と、分割体と製作板43との間に介設される縁切り材6とを備えている。縁切り材6は、分割体に水平力を作用させた際に架台4と分割体との間に発生する抵抗力を低減可能である。【選択図】図5
