Construction method for pre-arching steel structure roof truss of super high-rise building
The invention discloses a construction method for a pre-arching steel structure roof truss of a super high-rise building, and belongs to the technical field of construction of eccentric inclined super high-rise buildings. Comprising the following construction steps that S1, arching design is conducted on the large-span truss in an arc curve arching mode, and segmented manufacturing is conducted on the large-span truss according to the construction environment and working conditions; s2, pre-assembling the plurality of trusses which are manufactured in sections, and checking the accuracy of truss arching and important nodes; s3, the structural form of the supporting jig frame is designed, the supporting jig frame is arranged on a construction site, and then the truss is hoisted and assembled; s4, measuring and correcting a large-span truss formed by splicing a plurality of sections of trusses; and S5, a rear welding point is reserved, soil covering is conducted on the top face of the roof truss, and welding operation is conducted on the truss after soil covering is completed. The construction method is used for solving the construction difficulty of the roof truss involved in the eccentric inclined super high-rise building.
本发明公开了一种超高层建筑预起拱钢结构屋盖桁架施工方法，属于一偏心倾斜超高层建筑的施工技术领域。包括如下施工步骤：S1、采用弧形曲线起拱的方式对大跨度桁架进行起拱设计，并根据施工环境和工况对大跨度桁架进行分段制作；S2、对分段制作完成之后的若干桁架进行预拼装，检验桁架起拱和重要节点的精度；S3、设计支撑胎架的结构形式，并布设于施工现场，然后对桁架进行吊装拼装；S4、对多段桁架拼装形成的大跨度桁架进行测量校正；S5、预留后焊接点，并对屋盖桁架顶面进行覆土，覆土完成后再对桁架进行焊接操作。本施工方法用以解决偏心倾斜超高层建筑中所涉及到的屋盖桁架施工难点。
