Section steel column for high-rise building section steel concrete combination structure, and construction method thereof

Abstract

The present invention discloses a construction method of a section steel column for a high-rise building section steel concrete combination structure. The section steel column comprises a plurality of column sections, wherein the column sections are sequentially connected from bottom to top, an interface position of two optionally adjacent column sections is provided with an inner sleeve interface, and an outer side wall of a connection position of the two adjacent column sections is provided with a buckle fixation type assembly. The construction method comprises that: the insert-connection type initial positioning of the two adjacent column sections is achieved through the inner sleeve interface; the cross extending line and the buckle fixation type assembly are combined to carry out positioning correction on the column; a scale measurement method is adopted to carry out column scale height adjustment; and the cross extending line and the buckle fixation type assembly are combined to carry out verticality correction on the full length of the column sections. With the section steel column of the present invention, the model of one construction interface in each floor of the traditional section steel column can be increased to the model of one construction interface in every two floors or three floors, such that more than half of the construction interfaces of the section steel column can be saved, the probability of deviation error due to construction interface operation can be greatly reduced, and the guarantee degree of installation quality can be improved.

Description

technical field [0001] The invention relates to the technical field of beam-column structure construction in civil engineering, in particular to a steel-shaped column for a high-rise building steel-concrete composite structure and a construction method thereof. Background technique [0002] With the improvement of architectural design level, people's requirements for high space and wide plane of buildings have become high-end. In addition to the requirements for high space and long span floors, the commercial floors and entrance halls of high-rise buildings also require wall column sections in plane layout. The occupied area is the smallest, and the usable area is the largest, so as to achieve the good effect of building function. These high-space and long-span floors are often located at the bottom of high-rise buildings, and the bearing capacity of beams and columns is large, so the cross-sectional size of reinforced concrete beams and columns is required to increase accor...

AI Technical Summary

Problems solved by technology

[0003] In the traditional steel-concrete composite structure, the steel columns generally need to be hoisted on each floor, and there are many construction interfaces, and the hoisting workload is large and the construction period is long; the positioning of the steel columns lacks safe, effective and accurate adjustment components and adjustment methods, so the positioning of the steel columns The accuracy is low, and it is impossible to effectively guarantee the important quality indicators of the code, such as the verticality of the steel column, the accuracy of the elevation, the horizontal rotation deviation angle of the column section is 0°, the distance between the steel and the steel bar, the thickness of the steel protective layer, and the thickness of the reinforced concrete protective layer.
