Problems solved by technology
The traditional prefabricated shear wall structure formwork is fixed, and the formwork needs to be reset when the wall thickness is changed, which increases the cost of prefabrication
Moreover, it is difficult to hoist the prefabricated shear wall without hoisting parts, and the prefabricated shear wall is easy to be damaged during the hoisting process.

Embodiment Construction
[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0027] like Figure 1-5 As shown, a prefabricated prefabricated core tube with adjustable size includes prefabricated shear walls 1 connected in sequence. Prefabricated steel pipe-constrained steel-concrete columns 2 are arranged at all places, and the prefabricated steel-pipe-constrained steel-concrete columns 2 are connected to the prefabricated shear wall 1 through variable connecting stirrups 3, which are connected and fixed on the prefabricated Inside the shear wall 1. The shear wall connecting longitudinal reinforcement 5 is used for the connection between the prefabricated shear walls 1 . The variable connecting stirrup 3 is connected with the prefabricated shear wall 1 and the prefabricated steel pipe-constrained steel concrete column 2 .
[0028] The size of the variable connection stirrup 3 can be adjusted according to the size of ...

The invention discloses a size-adjustable prefabricated assembled core tube and a construction method thereof, belonging to the technical field of prefabricated assembly. The size-adjustable novel prefabricated assembled core tube includes prefabricated shear walls, prefabricated steel pipe-constrained steel concrete columns, Variable connection stirrups, double-pass connection joints of steel bars, longitudinal bars connected by shear walls; prefabricated shear walls are composed of two new prefabricated wall panels, corrugated steel bars, and wall panel connection steel bars; prefabricated steel pipe-constrained steel concrete columns are composed of prefabricated opening Composed of steel pipes and cross-shaped steel. The variable connection stirrup is connected with the prefabricated shear wall and prefabricated steel pipe-constrained steel concrete column. The size can be adjusted according to the size of the prefabricated shear wall and prefabricated steel pipe-constrained steel concrete column. The size can be changed flexibly, and the stirrup cage is automatically formed without Manual lashing. The new size-adjustable prefabricated core tube overcomes the formwork problem caused by the size fluctuation of the prefabricated structural core tube, as well as the problems of hoisting, installation and connection of prefabricated components.
Description
technical field [0001] The invention belongs to the technical field of prefabrication and assembly, and in particular relates to a size-adjustable prefabrication assembly type core tube and a construction method thereof. Background technique [0002] Prefabricated buildings are currently hot, and the state strongly supports the development of prefabricated buildings. The traditional prefabricated shear wall structure formwork is fixed, and the formwork needs to be reset to change the wall thickness, which increases the cost of prefabrication. Moreover, it is very difficult to hoist the prefabricated shear wall without hoisting accessories, and the prefabricated shear wall is easy to be damaged during the hoisting process. Therefore, the solution to the problem of factory prefabricated formwork and on-site hoisting of prefabricated shear walls is bound to become a problem that needs to be solved in the development of prefabricated buildings. And the core tube is the main st...
