Block hoisting construction method for large-span spherical-crown-shaped bolt-sphere joint net rack
The invention discloses a block hoisting construction method for a large-span spherical-crown-shaped bolt-sphere joint net rack. The block hoisting construction method comprises the following steps that net rack components enter a site for acceptance inspection; paying-off and wire inspection on supporting points are carried out; two grid frames at the bottom are spliced into middle splicing units on the ground in a segmented mode; the second circle of net rack is spliced into small splicing units on the ground, the small splicing units are sequentially hoisted for high-altitude bulk packaging, and then the second circle of net rack is folded; the third circle of net rack is assembled and folded according to the same method, and the rest of net racks are assembled in the same way; and the assembled net rack is checked and accepted. According to the construction method, the construction method that the large-span spherical-crown-shaped bolt-sphere joint net rack is assembled on the ground and hoisted in a blocking mode is adopted, the construction period is shortened, and the influence on production can be reduced in the construction process.
本发明公开了大跨度球冠形螺栓球节点网架分块吊装施工方法，包括以下步骤：对网架构件进场进行验收；支承点进行放线、验线；将底部两格网架分段地面拼装成中拼单元；第二圈网架在地面拼成小拼单元，依次吊装进行高空散装，然后将第二圈网架合拢；按照相同的方法拼装合拢第三圈网架，依次类推将剩余网架拼装完成；对拼装好的网架进行验收。本发明采用大跨度球冠形螺栓球节点网架地面拼装、分块吊装的施工方法，不仅缩短了施工工期，而且在施工过程可以减少对生产的影响。
