Large-sized steel structure integral translation and hoisting combination construction process

Abstract

The invention discloses a large-sized steel structure integral translation and hoisting combination construction process, which is characterized in that a large-sized steel structure is divided into a plurality of roof truss internodes, and comprises the following steps that: A. internodes assembling the plurality of roof truss internodes on a translation device, and adopting the plurality of roof truss internodes which are assembled on the translation device as a section; B. utilizing the translation device to move the plurality of roof truss internodes which are used as the same section to a hoisting position; C. and utilizing a hoisting device to integrally hoist the plurality of roof truss internodes of the same section to a designed position so as to assemble and join the connection of the roof truss. The process solves the problems that when constructing the large-sized steel structure that the size of the integral structure is large, the span of a specially-shaped structure is large, the control difficulty of the structure stability and deformation is large, the restriction on the peripheral environment and the additional structure is multiple, the cross of the previous and the next procedures is multiple, the node structure is unique, and the like, and has the advantages of high installation precision and short construction period.
