METHOD FOR REMOVING FILLET-WELDED PLATE
PROBLEM TO BE SOLVED: To provide a method for removing a fillet-welded plate that enhances work safety and stabilizes work quality and time, at the same time allowing prompt removal of a plate.SOLUTION: In a method for removing a filled-welded plate, a plate is cut first in a straight line in the vertical direction orthogonal to the planar direction, using a vertical cutter 20, at each of the cutting lines La to Ld positioned at inner side of each of the inner lines 10a2 to 10d2 of each of the beads 10a1 to 10d1. This separates a base plate 10 into welding plate parts 10A to 10H on the peripheral side with beads 10a1 to 10d1, respectively, and a non-welded plate part 10X in the central side without a bead. Next, the non-welded plate part 10X is removed from an upper flange 2a of a main girder 2. Then, each of the beads 10a1 to 10d1 of the welding plate parts 10A to 10H is cut in a straight line in the planar direction using a horizontal cutter 40, thus removing each of the plates 10A to 10H from the upper flange 2a.
【課題】作業の安全性を向上させつつ、作業品質及び作業時間を安定させることができて、プレートを早く撤去することができる隅肉溶接プレートの撤去方法を提供すること。【解決手段】隅肉溶接プレートの撤去方法では、先ず、各ビード１０ａ１〜１０ｄ１の各内側ライン１０ａ２〜１０ｄ２より内側に位置する各切断ラインＬａ〜Ｌｄで、平面方向と直交する縦方向から縦方向切断機２０を用いて直線状に切断する。これにより、ベースプレート１０を、周縁側で各ビード１０ａ１〜１０ｄ１がある各溶着プレート部１０Ａ〜１０Ｈと、中央側でビードがない未溶着プレート部１０Ｘとに分ける。次に、未溶着プレート部１０Ｘを主桁２の上フランジ２ａから取り外す。続いて、各溶着プレート部１０Ａ〜１０Ｈの各ビード１０ａ１〜１０ｄ１を平面方向から水平方向切断機４０を用いて直線状に切断し、各溶着プレート部１０Ａ〜１０Ｈを上フランジ２ａから取り外す。【選択図】 図７
