Embodiment 1

[0037] like figure 1 Shown is the flow chart of the construction method of the cross-section H-shaped steel stiff column. Specifically include the following steps:

[0038] 1. Measurement and positioning: Before installing the cross-section H-shaped steel stiff column, measure and design the embedded parts and mark the cross axis of each installed steel column, as the basis for the installation and positioning of the steel column and control the installation parameters;

[0039] (1) Calculation of control line data and layout of embedded part control lines

[0040] Calculate the relative positional relationship between each embedded part positioning template and the axis. After the first concrete pouring of the civil construction pile is completed and the construction of the waterproof protective layer is completed, the control line of the positioning formwork is respectively projected on the surface of the first pouring of the reaming pile and the surface of the cushion lay...

Abstract

The invention discloses a construction method for an H-type steel stiff column with a cross fracture surface. The construction method includes the steps of measuring and positioning, inspecting and checking before hoisting the H-type steel stiff column, hoisting the H-type steel stiff column in place, fixing the H-type steel stiff column temporarily, correcting the H-type steel stiff column, fixing the H-type steel stiff column, welding H-type steel stiff column and the like. The axis and perpendicularity of section steel column installation can be controlled accurately, structural construction is high in precision, construction quality is reliable, and the construction method is suitable for installation and construction of the H-type steel stiff columns with the cross fracture surfaces in a high-rise building, a super high-rise building, a long-span structure and a common structure.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to a construction method of a cross-section H-shaped steel stiff column, which is suitable for the installation and construction of the cross-section H-shaped steel stiff column of high-rise buildings, super high-rise buildings, long-span structures and general structures. Background technique [0002] With the development of the national economy and the rise of high-rise and super high-rise buildings, the height of single buildings is getting higher and higher. As a form of cross-section H-shaped steel stiff column commonly used in steel concrete (SRC) structures, it has bearing capacity. High, high rigidity and good seismic performance have been more and more used in long-span structures, high-rise buildings and super high-rise buildings. [0003] During the installation process of the existing cross-section H-shaped steel stiff column, the axis and verticality are not easy...
