【 摘 要 】

The large span spatial steel was used in chop manufactory of the Chengdu integrated circuit manufacturing project. Because the steel truss was of great importance and the span of the single one was large, the crane was difficult to cover the aerial platform. Overhead accumulative slip construction scheme was based on construction conditions of engineering site. This paper introduced construction process of slippage of unequal height and the selection of equipment and preparatory work before sliding. At the same time, in view of the special unequal height support of the project, the heavy and difficult points of construction were analyzed. The state of the structure in the sliding process and the possible adverse effects on the slip were analyzed in detail, and some suggestions were put forward. To ensure the safety and reliability of the slip construction scheme, the bending, synchronism and the stress of key member of the structure were monitored during the sliding process.
