Abstract
【解決手段】 レグ5の下端部27をピン11で支持した昇降装置3a、昇降装置3bを橋梁桁25の両端部付近に配置し、上げ越し状態とした橋梁桁25の端部付近を、ピン69を用いて支持梁9に結合する。次に、橋梁桁25を上昇させ、橋梁桁25の上げ越しがなくなった時点で、連結鋼材53を用いてピン69の回転を固定する。そして、橋梁桁25をさらに昇降させて片端を橋脚77に支持させた後、橋梁桁25の昇降装置3a側を下降させる作業と、レグ5の支持部23aをタフローラ13を用いて水平移動させる作業とを繰り返すことにより、橋脚77を支点として橋梁桁25を回転させ、橋梁桁25の他端を橋台79に支持させる。
