Construction method of large-diameter steel pipe column ring beam and operation platform

Abstract

The invention discloses a construction method of a large-diameter steel pipe column ring beam and an operation platform. The operation platform comprises a three-dimensional steel pipe frame composedof vertical steel pipes and transverse steel pipes, top steel bar supports are arranged at the tops of the vertical steel pipes, and horizontal steel bar supports are in inserted connection with the two ends of each transverse steel pipe. The prefabricated steel bar ring beam operation platform is used for overall manufacturing of ring beam steel bars, and the ring beam is hoisted and installed after manufacturing, so that the problems that on-site splicing of the ring beam steel bars and installation of steel bars are difficult, and quality is not easy to control are solved; pre-assembling work of the ring beam steel bars can be conveniently carried out in a steel bar machining area, manufacturing and machining of the ring beam steel bars can be ensured, the construction is convenient, the method is economic and practical, and the construction period is shortened. The structure is simple, the field installation efficiency is high, the quality is reliable, the construction period is short, and the labor intensity is low; all the components can be machined on the site and are directly assembled, so that the construction period is short; the construction quality meets drawing requirements.

Description

technical field [0001] The invention relates to a construction method and an operation platform of a large-diameter steel pipe column ring beam, belonging to the technical field of foundation and foundation construction in construction engineering. Background technique [0002] In super high-rise buildings, circular steel pipe columns are mostly used as vertical force transmission components. Such as figure 2 As shown, the current beam-column joints mostly use the ring beam connection form due to the cross-sectional characteristics of the circular steel pipe column. However, most of the existing ring beams are processed by traditional semi-finished products and then installed on site. This method leads to low work efficiency, Quality control is difficult and cannot meet the actual production requirements on site. Contents of the invention [0003] The object of the present invention is to provide a construction method and operating platform for large-diameter steel pipe ...
