Construction method for realizing perforation hoisting of upper-layer super-long steel structure through lower-layer net rack
The invention provides a construction method for realizing perforation hoisting of an upper-layer super-long steel structure through a lower-layer net rack, and relates to the technical field of building construction.The construction method comprises the steps that S1, a guide rail is laid at the upper end of the lower-layer net rack, and a movable transport vehicle is arranged; s2, a crane is arranged below the lower-layer net rack, and a suspension arm of the crane penetrates through the lower-layer net rack; s3, a crane is used for vertically hoisting the steel column to the position above the lower-layer net rack, and the steel column is moved to the installation point position to be installed; s4, transporting the steel beam to a hoisting operation point position by adopting a mobile transport vehicle, hoisting the steel beam to the upper end of the steel column by using a crane, and connecting the steel beam and the steel column to form a truss of steel frame; and S5, the steps S2-S4 are repeated to form a plurality of steel frames, and the steel frames are connected. Compared with a traditional construction technology, construction of the lower-layer net rack is not affected, overall lifting is not needed, other procedures are not affected, the overall construction period is shortened, the overall lifting risk and construction difficulty are reduced, and the problems that in the prior art, steel structure installation construction of the upper layer of a net rack steel structure factory building is large in difficulty, long in construction period, large in risk and the like are solved.
本发明提出一种透过下层网架实现上层超长钢结构穿孔吊装的施工工法，涉及建筑施工技术领域，包括：S1、在下层网架上端铺设导轨，设置移动运输车；S2、在下层网架下方设置吊车，使吊车吊臂穿过下层网架；S3、使用吊车垂直吊装钢柱至下层网架上方，将钢柱移动至安装点位安装；S4、采用移动运输车运输钢梁至吊装作业点位，使用吊车起吊钢梁至钢柱上端，连接钢梁和钢柱，形成一榀钢架；S5、重复步骤S2‑S4形成多榀钢架，进行钢架间的连接。较传统施工技术相比，不影响下层网架施工，无需整体提升，对其余工序无影响，节约整体施工工期，降低整体提升风险与施工难度，解决现有技术中网架钢结构厂房上层的钢结构安装施工难度大、工期长、风险大等问题。
