摘　　要：介绍了某艺术楼工程45m跨型钢桁架屋架(屋顶标高为29.57m和39.66m)的施工技术和施工方法。其安装方案是:高空拼装平台、滑移梁安装、轨道铺设→纵桁架的吊装、校正→横桁架的安装固定→屋面支撑的安装→屋面次梁的安装→逐步滑移→应力消除→就位卸载。已拼装好的桁架在端头各采用1台7150型履带式起重机吊装至高空平台上。屋面桁架在高空平台组装完2榀后,即2组桁架组成一个滑移单元,然后逐步累积滑移,如此反复,直至全部桁架滑移完成。The construction scheme and technology of a art building with 45m-span steel truss roof,roof elevation is 29.57m and 39.66m respectively,is given out.Its installation scheme is： firstly,assembling the high platform,installing the sliding beam,and laying the rail.Secondly,lifting and checking the longitudinal truss.Thirdly,installing and fixing the transverse truss.Fourthly,installing the roof support and its secondly beam.Finally,sliding the truss by steps,eliminating member stress and gradually unloading.Already assembled truss is lift to high platform by two 7150 type crawler cranes in the two ends.Two groups truss are assembled to a slip unit which gradually slides until to finish all truss sliding.
