Document Type and Number:
WIPO Patent Application WO/2021/073513
Kind Code:
A1
Abstract:
Disclosed in the present invention is a construction method combining a cast-in-place cylinder structure with a fabricated frame structure, mainly applied in the field of construction engineering for high-rise building construction, and high in construction speed, and also ensuring the overall stiffness of a building. The construction method comprises: 1. first constructing a cast-in-place cylinder part to the third-floor topping elevation by utilizing a slip-form construction technology; 2. carrying out hoisting and assembling operation on first-floor and second-floor fabricated frame structures; 3. enabling a vertical reinforcement cage to penetrate through a plurality of U-shaped rebars of first-floor and second-floor frame girders A, and placing the bottom of the vertical reinforcement cage to a foundation top surface of the cylinder; 4. pouring concrete in a cavity of a vertical through hole to enable the cast-in-place concrete to fill the vertical through hole and cavities of a plurality of horizontal holes, and after the concrete reaches certain strength, carrying out slip-form construction on third-floor and fourth-layer cylinders. The construction method for other floors can be carried out in the same manner; the plurality of U-shaped rebars are pre-embedded in joint ends of the frame girders A and the cylinders, and the plurality of U-shaped rebars are in one-to-one correspondence to the plurality of horizontal holes in position.
