BEARING REPLACEMENT METHOD FOR EXISTING CONCRETE BEAM
To provide a bearing replacement method for an existing concrete beam which can keep a wide work space, prevent inverse placement of concrete, minimize damage of concrete beam due to a replacement construction as low as possible, and minimize the sharing time in unstable temporary bearing as short as possible.SOLUTION: A bearing replacement method for an existing concrete beam in which an existing bearing 4 interposed between an existing concrete beam 5 and an understructure 2 is replaced with a new bearing S, the method executing a steps of: attaching an anchoring block for attaching an anchoring block 10 for anchoring an anchor A2 of an upper shoe of the new bearing S adjacent the existing bearing 4 and beside the existing concrete beam 5; and drilling an anchor hole for drilling an anchor hole 20 for inserting an anchor A1 of a lower shoe of the new bearing S on an understructure 2 of the new bearing 4 while bearing the existing concrete beam 5 by the existing bearing 4.SELECTED DRAWING: Figure 6
【課題】作業空間を広くとることができ、コンクリート打設が逆打ちとならず、取替工事によるコンクリート桁の損傷を極力小さくできるとともに、不安定な仮支承での共用期間を極力短くすることができる既設コンクリート桁の支承取替工法を提供する。【解決手段】既設コンクリート桁５と下部構造２との間に介装された既設支承４を新設支承Ｓに取り替える既設コンクリート桁の支承取替工法において、既設支承４の近傍の既設コンクリート桁５の脇に新設支承Ｓの上沓のアンカーＡ２を定着させる定着ブロック１０を取り付ける定着ブロック取付工程と、既設支承４で既設コンクリート桁５支承しつつ、既設支承４の脇の下部構造２に新設支承Ｓの下沓のアンカーＡ１を挿置するためのアンカー孔２０を削孔するアンカー孔削孔工程を行う。【選択図】図６
