Title:
TUBULAR COLUMN FOR PRESTRESSED ANCHOR ROD, ANCHOR ROD, AND CONSTRUCTION PROCESS
Document Type and Number:
WIPO Patent Application WO/2021/223399
Kind Code:
A1
Abstract:
Provided is a tubular column for a prestressed anti-floating tensile steel bar combined anchor rod, the tubular column comprising a tubular column which is prefabricated with concrete and is provided with a steel bar framework and is a tubular column accommodating an anchor rod steel bar, the column having an inner diameter of 3-7 cm and an outer diameter of 14-30 cm, wherein a steel bar framework is provided in the tubular column prefabricated with concrete. A combined anchor rod is a pre-tensioned prestressed anti-floating tensile steel bar anchor rod, the tubular column is a tubular-column-shaped outer sleeve of anchor rod steel bar, the anchor rod steel bar passes through the tubular column, and bearing plates each having a hole in the center and being larger than the inner diameter of the tubular column are disposed at two ends of the finished tubular column. When stress is applied to the anchor rod exposed out of a surface of the bearing plates, the steel bar ends are fixed to the bearing plates by means of nuts, or the steel bar ends are welded and fixed to the bearing plates. The steel bar may be a single finish-rolled anchor rod steel bar or multiple finish-rolled anchor rod steel bars, and in the case of multiple finish-rolled anchor rod steel bars, the bearing plates need to be provided with multiple holes and prestress application devices for multiple steel bars.
