SUSPENSION METHOD AND SUSPENSION STRUCTURE
PROBLEM TO BE SOLVED: To provide a suspension method and a suspension structure which suppress bending of a reinforcement cage.SOLUTION: A suspension method and a suspension structure relate to suspension of a box girder block reinforcement cage 150 in accordance with an overhanging construction method. The reinforcement cage 150 has a bottom slab reinforcement part 11 and a pair of side wall reinforcement parts 13. The suspension method comprises: installing first suspension support beam members 21 extending in the bridge axis direction under bottom slab reinforcement bars 17 of the bottom slab reinforcement part 11; installing second suspension support beam members 23 extending in a direction perpendicular to the bridge axis above the bottom slab reinforcement bars 17 and connected to the first suspension support beam member 21 with the bottom slab reinforcement bars 17 interposed therebetween; installing suspension support tensile members 35 extending almost vertically past the center portion of the side wall reinforcement parts 13 to suspend and support the second suspension support beam members 23 from both ends; installing a pair of suspension devices 37 above each of the pair of side wall reinforcement parts 13, with the upper ends of the plurality of suspension support tensile members 35 respectively connected; and suspending the pair of suspension devices 37 using prescribed suspension means.SELECTED DRAWING: Figure 6
【課題】鉄筋籠の撓みを抑制する吊下げ方法及び吊下げ構造を提供する。【解決手段】吊下げ方法及び吊下げ構造は、張出架設工法に係る箱桁ブロック用の鉄筋籠１５０の吊下げに関し、当該鉄筋籠１５０は、底版鉄筋部１１と、一対の側壁鉄筋部１３と、を有する。底版鉄筋部１１の底版下筋１７の下方で橋軸方向に延在する第１吊受梁材２１と、底版下筋１７の上方において橋軸直角方向に延在し底版下筋１７等を挟んで第１吊受梁材２１に連結された第２吊受梁材２３と、側壁鉄筋部１３の中央部を通過して略鉛直に延在し第２吊受梁材２３を両持ちで吊下げ支持する吊受張力材３５と、一対の側壁鉄筋部１３の各々の上方に配置され、各々に複数の吊受張力材３５の上端部が連結される一対の吊込装置３７と、が設置され、一対の吊込装置３７が所定の吊下手段によって吊下げられる。【選択図】図６
