36m 预应力混凝土折线形屋架是我国目前常用屋架中跨度最大者之一,由于屋架的跨度大,施工技术比较复杂;加上采用这种屋架的厂房都比较高大,下弦的标高常在16m 以上,给屋架的安装带来了一定的困难,施工中稍不注意,易产生质量事故。现就这种屋架在扶直吊装的过程中的一些技术问题,总结归纳如下,供参考。一、扶直吊装的过程中屋架要否绑杉杆的问题
The 36m prestressed concrete foldable roof truss is one of the most widely used roof spans in China. Due to the large span of the roof truss, the construction technology is relatively complex. The factory buildings with such roof truss are tall, and the elevation of the lower string is often more than 16m. The installation of the truss brings certain difficulties, and little care is taken during construction, which can easily lead to quality accidents. Some technical problems in the process of lifting and erecting the roof truss are summarized here for reference. First, whether the truss should be tied to the pine pole during straightening and lifting
