Embodiment Construction
[0050] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0051] The purpose of the present invention is to provide a segmented hoisting construction method for large-span super-high steel frames, which solves the problem of large span, high storey height, large changes in high and low spans, and self-heavy. If the construction is carried out according to the traditional technology, not only It is complicated, and the construction efficiency is low, and the position of the components is difficult to control accurately, the stability of the connection between the components cannot be guaranteed, the overall strength of the frame is poor, and it is difficult to meet the technical problems of the structural force requirements.

A large span ultrahigh section steel framework segmented hoisting construction method comprising the following steps: flowing main structure construction, and pre-burying foundation bolts; segmentally mounting a section steel column; inspecting the main concrete structure before hoisting; setting out a section steel column mount axis control line and a section steel column mount elevation control line; carrying out rectification after each hoisting step in segmental hoisting, which includes column foot elevation regulation, column foot axis regulation and column body verticality rectification; hoisting section steel girders, using temporary bolts for fastening same, and finally carrying out high intensity bolt connection and welding. The invention provides a reasonable construction method for hoisting the large span ultrahigh section steel framework; pre-install preparation, fixing member positioning, and contentious rectification in an install process can ensure the members to have accurate positions; the members are stably connected with high intensity, thus satisfying structure force bearing requirements; the method is simple in hoisting, high in construction efficiency, and can satisfy construction quality requirements.
Description
technical field [0001] The invention relates to a segmental hoisting construction method of a large-span super-high steel frame, in particular to a segmental hoisting construction method of a large-span super-high steel frame. Background technique [0002] In the construction of construction projects, the form of building structure is becoming more and more novel and complex. In addition to the traditional masonry structure and reinforced concrete structure, the application of steel structure, steel structure and reinforced concrete mixed structure is also becoming more and more extensive. Sectional steel frames are mainly used in large-scale public buildings. This type of building structure often has the characteristics of large spans, high storey heights, large changes in high and low spans, and self-heaviness. If the construction is carried out according to the traditional technology, not only the operation is complicated, but also the construction efficiency is low, and ...
