The steel structure roof hydraulic lifting device comprises a support arranged at the top ends of two concrete columns, a hydraulic lifter and a steel strand, a truss is placed between the two concrete columns, the support is fixedly connected with the concrete columns, the hydraulic lifter is fixedly connected with the support, the steel strand is arranged between the hydraulic lifter and the truss, the two endsof the steel strand are fixedly connected with the hydraulic lifter and the truss respectively, and a balance detection device is arranged at the bottom end of the truss. The steel structure roof hydraulic lifting device has the effect of reducing the operation risk in the truss mounting process.
Description
technical field [0001] The present application relates to the technical field of steel structure hydraulic lifting, in particular to a steel structure roof hydraulic lifting device and its construction method. Background technique [0002] At present, with the rapid development of steel structure technology, more and more steel structures have entered people's lives. The existing steel structures are usually combined with concrete columns as roofs, especially for venues and exhibition halls. [0003] Most of the existing steel structure roofs use a plurality of long-span trusses as supports, and the two ends of the long-span trusses are respectively fixedly connected with two concrete columns. When installing the truss, the truss is usually transported to the construction site, and then the truss is lifted to the designated position by a crane, and then the truss is welded and fixed in sequence at high altitude. [0004] Regarding the above-mentioned related technologies, t...
