Method for integral staggered lifting and horizontal sliding of corridor steel structure
The invention provides a method for integral staggered lifting and horizontal sliding of a corridor steel structure. The method comprises the steps that S1, a steel truss is assembled on a basement top plate, a lifting platform is installed, a lifter is placed, and the lifter is connected with a lower lifting appliance through a steel strand; s2, after the truss lifting section is assembled, a lifter is subjected to graded loading, the whole truss lifting section is separated from the assembling jig frame by about 100 mm, and lifting is stopped; locking the hydraulic cylinder, standing for 12 hours, and checking whether welding seams and deformation of the structure, the temporary rod piece, the lifting point and the lifting platform are normal or not; s3, after checking, integrally and synchronously lifting to a position 50mm right above the designed elevation; s4, the hydraulic cylinder is locked, and pushing sliding construction is prepared; s5, the corridor is synchronously pushed and slid to the position over the designed elevation; and S6, a hydraulic lifter is adjusted, the corridor is synchronously lowered to the designed elevation position, after unloading is completed, a post-installation rod piece is installed, and lifting sliding equipment is dismantled.
本发明提供了一种连廊钢构整体错位提升及水平滑移的方法。所述方法包括：S1：在地下室顶板拼装钢桁架，安装提升平台，放置提升器，提升器通过钢绞线与下吊具连接；S2：桁架提升段拼装完成后，提升器分级加载，使其整体脱离拼装胎架约100mm，停止提升；液压缸锁紧，静置12小时，检查结构、临时杆件、提升吊点和提升平台的焊缝和变形是否正常；S3：检查无误后，整体同步提升至设计标高处正上方50mm处；S4：液压缸锁紧，准备顶推滑移施工；S5：将连廊同步顶推滑移至设计标高正上方；S6：调整液压提升器，将连廊同步下放至设计标高位置，卸载完成后安装后装杆件，拆除提升滑移设备。
