Title: ASSEMBLY TYPE STEEL PIPE CASING REINFORCED CONCRETE COMBINED JOINT AND MOUNTING METHOD
Abstract:
An assembly type steel pipe casing reinforced concrete combined joint and a mounting method, relating to the technical field of structural engineering, and for use in building column beams in a building structure. The combined joint comprises a high-strength outer-coating steel pipe, steel bar restraining plates, high-strength steel bars (5), conversion separation sleeves, and a common outer-coating steel pipe. The conversion separation sleeves are disposed at the upper end and the lower end of the common outer-coating steel pipe. The conversion separation sleeve at the upper end of the common outer-coating steel pipe is connected with the high-strength outer-coating steel pipe, and the conversion separation sleeve at the lower end of the common outer-coating steel pipe is connected with the high-strength outer-coating steel pipe. The high-strength steel bars (5) penetrate the whole common outer-coating steel pipe. The upper ends and the lower ends of the high-strength steel bars (5) are communicated with the interior of the high-strength outer-coating steel pipe. The high-strength steel bars (5) are connected with the conversion separation sleeves. The upper ends and the lower ends of the high-strength steel bars (5) are connected with the steel bar restraining plates. The combined joint well resolves the problems of unstable welding quality and long construction time due to the existence of a steel pipe welding segment during the construction using conventional column beams.
