Title:
PREFABRICATED THIN-WALLED HOLLOW PIER CONSTRUCTION METHOD BASED ON STEEL BAR POST-INSTALLATION
Document Type and Number:
WIPO Patent Application WO/2024/082720
Kind Code:
A1
Abstract:
A prefabricated thin-walled hollow pier construction method based on steel bar post-installation, comprising: dividing a pier column into a plurality of prefabricated sections, the plurality of sections being divided into two types of sections, i.e., I-type sections and II-type sections, wherein each I-type section is divided into two straight-plate modules and two U-shaped modules in the longitudinal direction, and each II-type section is divided into four L-shaped modules in the longitudinal direction; providing a main steel bar channel in the main steel bar position of each module, and providing a hoop steel bar channel in the hoop steel bar position of each of some of the modules of each section; installing the I-type sections and the II-type sections alternately at a pier position, during installation of each section, a hoop steel bar being inserted in each hoop steel bar channel and being connected to a preset hoop steel bar by means of a threaded sleeve, and main steel bars being inserted into main steel bar channels of upper and lower sections and being connected by means of threaded sleeves. The present invention greatly reduces the weight of each section of pier column, thereby facilitating transportation and installation, and the connection between the sections is firm, so that shear resistance is high.
