Construction method of large-span elevated station building steel structure grid roof
The invention relates to a construction method of a large-span elevated station building steel structure net rack roof, which comprises the following steps of: placing a channel steel base, arranging short upright posts and long upright posts, then placing bolt balls in sequence, and welding net rack cross rods and inclined rods to form net rack units by relying on the short upright posts and the long upright posts; the gate-type lifting frame unit lifts and assembles the net rack in the middle lifting area; a lifting platform device A and a lifting platform device B are arranged. The construction method has the beneficial effects that the hoisting form of high-altitude bulk loading and block lifting is adopted, all-round scaffolds are erected on the floors on the two sides for high-altitude bulk loading, a net rack in the middle area is spliced on the floors, and the construction efficiency of the steel structure net rack roof is improved; for the middle lifting area of the net rack, net rack units are installed through a gate-type lifting frame system, the net rack units and the high bulk area are spliced into a whole through supplementing rods after partition hydraulic lifting, and the construction quality of the steel structure net rack roof is guaranteed.
本发明涉及一种大跨度高架站房钢结构网架屋盖的施工方法，包括以下步骤：摆放槽钢底座，并设置短立柱和长立柱，随后依次摆放螺栓球，依托短立柱和长立柱焊接网架横杆和斜杆形成网架单元；门式提升架单元对中间提升区的网架进行提升和拼装；设置提升平台装置A和提升平台装置B。本发明的有益效果是：采用高空散装加分块提升的吊装形式，两侧采用在楼面上搭设满堂脚手架进行高空散装，中间区域网架在楼面上进行拼装，提高了钢结构网架屋盖的施工效率；对于网架的中间提升区，采用门式提升架体系安装网架单元，分区液压提升后与高空散装区通过补杆拼接成整体，保证了钢结构网架屋盖的施工质量。
