LIFTING DEVICE, AND BOX GIRDER BRIDGE BUILDING METHOD
To provide a box girder block capable of suppressing future deterioration.SOLUTION: A lifting device 20 for a box girder block 14 includes an upper floor slab 5, lower floor slab 6, and multiple webs 7; and a pair of lifting units 22 that are placed at a distance from each other in the direction perpendicular to the bridge axis of the box girder block 14 and connected to each other by a connecting member 21. Each of the lifting units includes: a beam 23 that is longer than the length of the upper floor slab 5 in the bridge axis direction and placed above the upper floor slab 5 along the bridge axis direction; a first support arm 24 that is provided to one end of the beam 23 and includes a first support piece 26 for supporting the upper floor slab 5 from the bottom; and a second support arm 25 that is slidably arranged on the other end of beam 23, and has a second support piece 27 for supporting the upper floor slab 5 from the bottom on the lower end. Since box girder block 14 can be supported from the bottom and lifted, there is no need to provide an insert member on the top surface of the box girder block 14.SELECTED DRAWING: Figure 4
【課題】箱桁ブロックの将来の劣化を抑制する。【解決手段】上床版５、下床版６及び複数のウェブ７を備える箱桁ブロック１４のための吊り上げ装置２０は、箱桁ブロック１４の橋軸直角方向に互いに離間して配置され、連結部材２１によって互いに連結された１対の吊り上げユニット２２を備える。吊り上げユニットのそれぞれは、上床版５の橋軸方向の長さよりも長く、上床版５の上方に橋軸方向に沿って配置されるビーム２３と、ビーム２３の一端に設けられ、上床版５を下方から支持する第１支持片２６を下端に備える第１支持アーム２４と、ビーム２３の他端側にスライド可能に設けられ、上床版５を下方から支持する第２支持片２７を下端に備える第２支持アーム２５とを含む。箱桁ブロック１４を下方から支持して吊り上げ可能であることから、箱桁ブロック１４の上面にインサート部材を設ける必要がない。【選択図】図４
