Embodiment 1）

[0031] See figure 1 , the construction method of the shaped steel column bracing frame of the super high-rise building frame column of the present embodiment, it is mainly implemented by the following steps:

[0032] ① Make the support frame: make the support frame 1 according to the design size, and the manufactured support frame 1 is a truss type support frame, such as figure 2 As shown, the support frame 1 is composed of vertical bars 11, cross bars 12, oblique bars 13 and top plate 14; the vertical bars 11 are vertically arranged with 4, and the horizontal bars 12 are arranged with 12 horizontal bars. The 12 horizontal bars are divided into upper, middle, and The lower three floors are set up, and each floor is provided with four. The four horizontal bars 12 on the upper floor connect the tops of the four vertical bars 11 in turn; the four horizontal bars 12 on the middle layer connect the middle parts of the four vertical bars 11 in turn. The bottoms of the four vertica...

Abstract

The invention provides a section-steel-column support frame construction method for a super-high-rise-building frame column. The method includes the steps that 1, a support frame is made; 2, bolts arefixedly arranged on the support frame through a calibration steel sleeve plate; 3, a concrete cushion of a building structure bottom plate is poured, and embedded parts are embedded; 4, the support frame is lifted and fixed; 5, lower reinforcing steel bars of the building structure bottom plate are bound and welded to the support frame; 6, slant supports are welded to the lower portion of the support frame; 7, a first steel column is fixedly installed on the support frame; 8, positions of section steel columns are corrected, and the section steel columns are anchored and fixed; 9, upper reinforcing steel bars of the building structure bottom plate are bound, and bottom plate concrete is poured; 10, a second steel column and rear steel columns are fixedly installed. According to the section-steel-column support frame construction method for the super-high-rise-building frame column, construction is easy, convenient, safe and reliable, the construction quality is easy to control, the embedded quality of the section steel columns in a foundation bottom plate or a ground beam can be guaranteed, and three problems that in a construction method for section steel columns of a traditionalbuilding structure frame column, the anchor bolt accuracy is poor, the stability of the support structure is poor, and as key construction procedures are occupied, the construction period is influenced are effectively solved.

Description

technical field [0001] The invention relates to a construction method for a pre-embedded foundation of a shaped steel column for a frame column of a super high-rise building, in particular to a construction method for a supporting frame of a shaped steel column for a frame column of a super high-rise building. Background technique [0002] In the vertical structure of super high-rise building projects, in order to reduce the section size of the frame column and increase the usable area, a large number of steel columns are used in the frame column as the skeleton to construct the steel concrete column. During construction, the steel column at the bottom is usually used and pre-buried The column foot bolts in the base plate concrete are fixed, so the construction quality of the embedded bolts directly affects the quality of the steel structure engineering of the entire building. The pre-embedded column bolts in the floor concrete are not only required to have no inclination, b...
