High-rising building construction method and device

Abstract

The invention discloses a high-rising building construction method and device. The high-rising building construction method comprises the following steps that A, a vertical shaft frame, an operation platform and a vertical transportation device are installed on a building foundation, the vertical shaft frame is sequentially provided with a plurality of pairs of jacking devices in the height direction, one end of each pair of jacking device is fixedly connected with the vertical shaft frame, the other end of each pair of jacking device is fixed to a bracket of the cylinder wall of a building, and the operation platform is in a radial shape, is of an upper hook structure and comprises a plurality of ring beams and a plurality of radial beams connected to the ring beams; B, a displacement type inner formwork of the construction layer is installed, and steel bar engineering construction of the construction layer is carried out; C, a displacement type outer formwork of the construction layer is installed, and concrete of the construction layer is poured; D, the displacement type formwork of the construction layer is dismantled and cleaned; and E, the operation platform is lifted to the next construction layer, and the steps B-D are repeated till the building reaches the preset elevation. The construction method is simple and feasible, the construction period is short, and the safety risk and the engineering cost are reduced.

Description

technical field [0001] The invention relates to a construction method in the construction field, in particular to a construction method and a construction device for a towering structure. Background technique [0002] Tall and large chimneys have many construction cycles, high requirements for construction joints and verticality control of the cylinder wall, and thin aluminum skin formwork used for the outer wall of the construction is easy to deform, and it is difficult to control the thickness of the cylinder body, the thickness of the protective layer, and the quality of appearance molding; the construction of tall and large chimneys is continuous, Process inspection and acceptance are intensive, and due to the high vertical height, it is difficult for inspectors to pass through, and most of them work at heights, requiring high safety control measures for people, objects, and the environment. [0003] At present, most domestic construction techniques for reinforced concre...

Problems solved by technology

[0002] Tall and large chimneys have many construction cycles, high requirements for construction joints and verticality control of the cylinder wall, and thin aluminum skin formwork used for the outer wall of the construction is easy to deform, and it is difficult to control the thickness of the cylinder body, the thickness of the protective layer, and the quality of appearance molding; the construction of tall and large chimneys is continuous, Intensive process inspection and acceptance, due to the high vertical height, it is difficult for inspectors to pass through, and most of them work at heights, requiring high safety control measures for people, objects and the environment

[0003] At present, most domestic construction techniques for reinforced concrete chimneys use hydraulic sliding formwork and electric (hydraulic) formwork lifting techniques, but these two construction techniques have more or less defects and relatively high construction costs
