The invention relates to the technical field of construction engineering, and specifically discloses a device for enhancing the force of an advanced construction core tube structure, including an upper platform, a lower platform and a first telescopic cylinder; A fixed frame with an included angle of 45° on the inner wall and several support frames, the support frame is connected to the fixed frame, fixed joints are provided at both ends of the fixed frame, and retractable clamping plates are arranged in the fixed joints; The support frame of the upper platform is provided with a hoisting mechanism; the first telescopic cylinder is a double-acting telescopic cylinder, the upper end of the first telescopic cylinder is connected with the upper platform, and the lower end of the first telescopic cylinder is connected with the lower platform; the lower platform The supporting frame is provided with L-shaped hanging scaffolds for people to climb; it also includes a number of card slots arranged on the inner wall of the core tube to cooperate with the clamping plates. The purpose of the present invention is to solve the problem that the core cylinder has poor lateral force resistance when the core cylinder is constructed in advance.
Description
technical field [0001] The invention relates to the field of building construction, and specifically discloses a device for enhancing the stress of the core tube structure in advance construction. Background technique [0002] In the construction of super high-rise buildings, in order to reduce the settlement difference between the core tube and the outer frame and speed up the construction progress, the core tube structure often adopts hydraulic climbing formwork or steel platform formwork system for advanced construction, that is, the core tube is constructed first, and then the peripheral steel tube of the core tube is constructed. Frame structure construction, and finally the outer frame column, floor structure construction and subsequent curtain wall installation. The advanced construction of the core tube can fully develop the shrinkage and creep of the concrete, reducing the deformation difference of the vertical components, the damage of the non-structural components...
