摘要
民航成都２０１机库网架重２１６７ｔ，平面尺寸１４０ｍ×８７ｍ，使用小型提升机具以及劲性柱与工具柱相结合的方法进行整体提升安装。提升过程中，利用机库建筑和临时支承系统，保证群柱和单肢的稳定；并且采用微机监测、远红外测距和近景摄影等先进技术，控制和调整提升与就位的同步，使网架在施工过程中的应力和变位满足设计要求，保证网架的安装精度。本文主要阐述网架整体提升安装法及提升工艺等。
Abstract The gird frame of Hangar#201 CAAC is installed by integral hoisting,the grid weighs 2167t,and its plan dimcnsion is 140m× 87m. Small hoisters,composite columns and tool columns are used for hoist-ing. Permanent building and temporary supports are used to stabilize columns in group &single. Computermonitoring,far infrared gear surveying,close shotting,and other advanced technology are used to controland adjust hoisting and shelving,so that the stresses and deformations are within the range of requirement,installation is precise. The integral hoisting of Hangar#201 contributes new experience and new way to ourcountry’s large span, heavy-duty frame installation. The paper describes grid frame installation method andhoisting technology.
