Longitudinal and transverse small section hoisting construction method for wide steel box girder
The invention discloses a hoisting construction device and method for longitudinal and transverse small segments of a wide steel box girder. A temporary support, a transverse bridge direction guide rail, a longitudinal bridge direction guide rail, a cushion block, a transverse center hole jack, a longitudinal center hole jack and a vertical jack are utilized, wherein the transverse bridge direction guide rail, the longitudinal bridge direction guide rail, the cushion block, the transverse center hole jack and the longitudinal center hole jack are installed on the top of the temporary support; the transverse center hole jack and the longitudinal center hole jack are respectively connected with the cushion block through the threaded connecting rod, and the vertical jack is installed between the top of the cushion block and the bottom of the steel box girder section. The transverse center hole jack and the longitudinal center hole jack act on the threaded connecting rod so as to drive the cushion block to move along the transverse bridge direction guide rail and the longitudinal bridge direction guide rail, then transverse or longitudinal position adjustment of the steel box girder section is achieved, and height position adjustment of the steel box girder section is achieved through the vertical jack. The problems that an existing wide steel box girder is large in construction difficulty, high in danger, low in efficiency and the like can be solved, the linear precision is high after a bridge is formed, and the method can well adapt to complex and changeable urban viaducts.
本发明公开了一种宽幅钢箱梁纵横向小节段吊装施工装置及施工方法，利用临时支架与其顶部安装的横桥向导轨、纵桥向导轨、垫块与横向穿心式千斤顶、纵向穿心式千斤顶与竖向千斤顶，横向穿心式千斤顶、纵向穿心式千斤顶分别通过螺纹连接杆与垫块连接，所述竖向千斤顶安装于垫块顶部与钢箱梁节段的底部之间，通过横向穿心式千斤顶、纵向穿心式千斤顶作用于螺纹连接杆从而带动所述垫块沿横桥向导轨、纵桥向导轨移动，进而实现钢箱梁节段的横向或纵向位置调节，通过竖向千斤顶实现钢箱梁节段的高度位置调节。能够解决现有宽幅钢箱梁施工难度大、危险性高、效率低等问题，并且成桥后线形精度高，能够良好的适应复杂多变的城市高架桥。
