摘要
我国铁路钢桥为了减少疲劳控制因素,对箱型杆件的端隔板箱口里侧缩短焊缝长度,在箱口外侧用密封剂进行密封,使箱体成为密封体,防止钢梁里侧腐蚀,以便延长钢桥的涂装寿命。
For decreasing the fatigue-controling factors of the railway steel bridge, the weld length in the inside of the box end clapboard of the box girder construction is shortened, and the outside of which is sealed by a sealant, which made the box sealed. The ways can prevent the girder from corroding; and the paint life of the steel bridge is lengthened.
