The invention provides a lower lifting point lifting device and a lower lifting point integrated integral lifting method, and relates to the field of steel structure engineering. The lifting device issymmetrically distributed on the circumference of a truss, and the lower lifting point lifting device comprises a lifting support, a hydraulic lifter, a steel strand, a lifting plate and two sets ofconnecting rods. According to the lower lifting point lifting device and the lower lifting point integrated integral lifting method, the lifting point form is simplified, three temporary rod pieces are omitted, the measure amount of a temporary structure is reduced, a large amount of high-altitude disassembling work after lifting in place is greatly reduced, and the construction period is shortened; and the truss is integrally lifted to the designed elevation, then rod piece welding and two sets of upper chords at the opening alignment position are carried out, the construction amount and construction difficulty of the site high altitude are greatly reduced, and the construction cost is reduced.

    本发明提供了一种下吊点提升装置及下吊点一体式整体提升方法,涉及钢结构工程领域,该提升装置对称分布在桁架的环周,下吊点提升装置包括提升支架、液压提升器、钢绞线、吊板以及两组连接杆,本发明简化了吊点形式,省去了三根临时杆件,减少了临时结构的措施量,也极大减少提升到位后大量的高空拆卸工作,节省工期;将桁架整体提升到设计标高,再进行对口处的杆件焊接和两组上弦杆,将大大降低现场高空的施工量和施工难度,减低施工成本。
