ZHANG YANGQING / LI YOULIN / ZHUANG XIAOZHUAN / ZHUANG GUANGQING

The invention discloses a single-column pier 102 steel cover beam swivel lifting installation method and a steel cover beam, the method is realized by means of the steel cover beam, and the method comprises the following steps: S1, carrying out steel bar detection on the single-column pier 102, carrying out anchor hole lofting, and then punching; s2, the steel cover beam is manufactured according to the steel bar detection result, the anchor hole lofting result and the punching result in the S1; s3, a jig frame 7 is assembled on the construction site, and lifting equipment is installed; s4, a steel cover beam is assembled on the jig frame 7 in the S3, and a steel hoop 2 of the steel cover beam is oppositely pulled through a bolt; s5, the steel cover beam assembled in the step S4 is lifted to the specified height through the lifting equipment in the step S3; s6, a swivel bracket 10 and a turntable are mounted between the steel cover beam in the S5 and the jig frame 7; s7, the rotating disc in the step S6 is rotated, so that the steel cover beam is rotated to a set position; and S8, a leveling steel plate 5 and a support 6 of the steel cover beam are installed. The method has the advantages that construction can be fast, the construction risk is reduced, and the method is not limited by clearance and site limitation.

本发明公开了独柱墩102钢盖梁转体提升安装方法及钢盖梁，该方法依靠钢盖梁实现，包括以下步骤：S1、对独柱墩102进行钢筋探测并进行锚栓孔放样，然后打孔；S2、根据S1中的钢筋探测结果、锚栓孔放样以及打孔结果制作钢盖梁；S3、在施工现场拼装胎架7以及安装提升设备；S4、在S3中的胎架7上拼装钢盖梁并将钢盖梁的钢抱箍2用螺栓对拉；S5、利用S3中的提升设备提升S4中拼装好的钢盖梁至指定高度；S6、在S5中的钢盖梁与胎架7之间安装转体支架10以及转盘；S7、转动S6中转盘使得钢盖梁转体到设定位置；S8、安装钢盖梁的调平钢板5和支座6。本发明具有可以快速施工，降低施工风险，不受制于净空及场地限制等优点。
