摘要
正交异性钢桥面板是钢结构桥梁的重要结构件,正交异性钢桥面板由钢板、U肋和横隔板组成。以钢箱梁正交异性钢桥面板为例,介绍正交异性钢桥面板结构特点和组拼、焊接及工地连接工艺特点,探讨在目前焊接和组装工艺条件下,延长正交异性钢桥面板使用寿命的加工技术和工艺。
The orthotropic steel bridge deck is important component of the steel structure bridge,which is composed by the steel plate,the U-shaped stiffener and the diaphragm.The structural feature and craft characteristic for assembling,welding and site connection of the orthotropic steel bridge deck are introduced.Under the condition of the current welding and assembling,technology and technique to prolong the service life of orthotropic steel bridge deck were researched and discussed.
