Large-volume steel net rack integral lifting device and construction method
The invention discloses a large-volume steel net rack integral lifting device. Lifting supporting columns are arranged outside side supporting structure columns; a lifting beam frame is installed between side lifting supporting columns in a supporting mode; the lifting beam frame is connected with a net rack lower chord preset lifting point through a hydraulic lifter; and the lifting supporting columns are connected with a net rack outer side lower chord preset lifting point through a chain block. A construction method includes the steps of determining initial offsets of an X axis and a Y axis; mounting the lifting support columns and the lifting beam frame; installing the hydraulic lifter and the chain block, and connecting the hydraulic lifter and the chain block with the net rack presetlifting point; and after lifting and adjusting, positioning and fixing a net rack. According to the large-volume steel net rack integral lifting device, the lifting supporting columns and the liftingbeam frame are arranged at the outer sides of the side supporting structure columns, so that a reserved mounting space is reduced, and the overall stability of the net rack is improved; the hydrauliclifter and the chain block are matched to lift the net rack, so that lifting control factors are reduced, adjustment is convenient, and the construction efficiency is improved; and the lifting supporting columns and the lifting beam frame are arranged on the outer side face of the net rack, so that dismounting is convenient, and the dismounting efficiency is high.
本发明公开了一种大体量钢网架整体提升装置，在边支撑结构柱外设提升支撑柱，边提升支撑柱之间支撑安装提升梁架，提升梁架通过液压提升器与网架下弦预设吊点连接，提升支撑柱通过手拉葫芦与网架外侧下弦预设吊点连接，施工方法的步骤为确定X轴和Y轴的初始偏移量；安装提升支撑柱、提升梁架；安装液压提升器、手拉葫芦并与网架预设吊点连接；进行提升、调整后定位固定网架；本发明通过在边支撑结构柱的外侧设置提升支撑柱、提升梁架，减少预留安装空间，提高网架整体稳定性；利用液压提升器和手拉葫芦配合对网架进行提升，减少提升控制因素，方便调整，提高施工效率；提升支撑柱和提升梁架设置在网架外侧面，方便拆卸，拆卸效率高。
