Prefabricated column with space steel truss platform and capable of realizing pitch point cast-in-situ connection

Abstract

The invention discloses a prefabricated column with a space steel truss platform and capable of realizing pitch point cast-in-situ connection. The prefabricated column comprises a column body, a plurality of longitudinal stress steel bars and a plurality of column inner stirrups, the longitudinal stress steel bars are distributed along the side edge of the column body, the two ends of the longitudinal stress steel bars penetrate out from the two ends of the column body respectively, a steel truss connection structure is arranged at one end of the column body, and the longitudinal stress steelbars are inclined to the corresponding side correspondingly; the steel truss connection structure comprises steel plate strip hoops, the steel bar connection structure, at least one longitudinal supporting steel bar and a plurality of pitch point stirrups, the plurality of pitch point stirrups are arranged on the part, penetrating out of the end part of the column body, of the longitudinal stresssteel bars in a sleeving mode, the longitudinal supporting steel bars are longitudinally arranged at the end part of the column body, the steel plate strip hoops sleeve the part, penetrating out of the end part of the column body, of the longitudinal stress steel bars, the positions between the adjacent longitudinal stress steel bars and between the longitudinal stress steel bars and the longitudinal supporting steel bars are connected through the steel bar connection structure, and a feeding channel is arranged at the lower end part of the column body. The prefabricated column can simplify the construction process and save the construction period.

Description

technical field [0001] The invention relates to a prefabricated column with a space steel truss platform which can realize node cast-in-place connection. Background technique [0002] The traditional housing construction technology has low production efficiency, slow construction speed, long construction period, high material consumption, serious construction site pollution and high labor intensity. These series of conditions can no longer meet the needs of my country's healthy and sustainable development of the construction industry. The prefabricated concrete building is widely used in various construction projects because of its efficient industrial production, intensive and fast construction process, and green and environmentally friendly construction process. [0003] At present, in the overall prefabricated concrete structure, the connection between the upper and lower columns is mainly connected by steel sleeve grouting. After the strength is strengthened, the steel ...

AI Technical Summary

Problems solved by technology

The above process has the following defects: the installation of the joint components needs to be carried out twice, which increases the construction period of the joint construction; the installation and connection of the sleeve and the steel bar have strict precision requirements, which increases the difficulty of construction; the steel bar and grouting in the sleeve cannot be detected material anchoring quality
