大跨度钢桁架的安装往往受到施工场地、塔式起重机起吊能力、工期及成本影响，安装难度较大。结合合肥华润万象城工程不等跨钢桁架的施工要求，设计一种特殊的滑移车架，利用设置在两侧支撑结构边的滑移导轨进行不同跨度和截面宽度钢桁架的滑移施工。工程应用证明，该滑移车架施工安全，节省了工期，降低了施工成本。

The installation of large span steel truss is often affected by the construction site, the tower crane lifting capacity, construction period and cost. Combined with the construction requirements of different span steel truss in Hefei MIXC, a special kind of sliding frame was designed,which used the sliding guide rail setting on both sides of the support structure to slide the different span and width steel truss. Through the engineering application, it proved that the sliding frame construction was safe, which saved the construction period and reduced cost.
