Hydraulic device for demounting steel structure supporting frames

Abstract

The invention relates to the technical field of hydraulic devices, in particular to a hydraulic device for demounting steel structure supporting frames. The hydraulic device comprises cross beams, longitudinal beams, hydraulic jacks, brackets, adjusting plates, back shores, triangular stiffening plates and a stiffening plate. At least three longitudinal beams are laid at the upper ends of the cross beams, the back shores are installed in the middles of the upper ends of the longitudinal beams, and at least five adjusting plates are bedded between the back shore at the upper portion and the back shore at the lower portion. When loads exist on the top, the top loads are transmitted to the longitudinal beams, then the loads can be transmitted to the cross beams through the longitudinal beams,enough work space is achieved, stability and safety of supporting frame demounting are ensured, and therefore multiple supporting frames can be demounted synchronously at the same time according to field requirements or structural design requirements, and down-warping deformation of a main structure is controlled; and the problem that after a large-span steel structure is spliced at the high altitude, a temporary supporting system of the large-span steel structure can be hardly stably demounted is solved.

Description

technical field [0001] The invention relates to the technical field of hydraulic devices, in particular to a hydraulic device for unloading a steel structure support frame. Background technique [0002] With the rapid development of my country's national economy, the development of urban construction is also increasing rapidly, and people's living standards are constantly improving. On this basis, people have put forward higher requirements for buildings, not only to meet the basic functions of life, work, and residence. It also pays more attention to the appearance, shape and compatibility with the surrounding environment of the building. In order to meet various requirements, the building structure becomes more and more complex. As the building forms become more and more diverse, high-altitude and long-span steel structures are becoming more and more popular. [0003] With the continuous emergence of various large-span steel structure buildings, various installation techniq...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a hydraulic device for unloading the steel structure support frame, which has the advantages of smoothly unloading the temporary support system after the high-altitude assembly of the large-span steel structure is completed, and solves the problem of unloading the large-span steel structure. After the high-altitude assembly of the span steel structure is completed, it is difficult to unload the temporary support system smoothly
