Prestressed construction process for building high-rise building structure

Abstract

The invention discloses a prestressed construction process for building a high-rise building structure. All steel wire ropes in prestressed tendons are dispersedly anchored through first anchor bearing plates and corresponding first anchorage devices, so that the problem that stress on the surrounding structure of the first anchor bearing plates is concentrated after tension releasing is avoided; all the first anchor bearing plates are arranged along the spherical surface, i.e. the bearing surfaces of all the first anchor bearing plates are supported by an imaginary sphere, so that the stress is more uniform, and the stability of the anchoring structure is facilitated; and second anchor bearing plates, cavity molds and templates are relatively fixed, so that holes, through which the prestressed tendons can penetrate, of the second anchor bearing plates, the cavity molds and the templates are not staggered, the prestressed tendons can be arranged to be perpendicular to the outer surfaces of the templates all the time, the process requirement is met, and accurate implementation of prestress of the high-rise building structure is guaranteed. The prestressed construction process has the advantages of simple steps, convenience in operation and good effect.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a prestressed construction technology for building high-rise building structures. Background technique [0002] The structure of modern high-rise buildings is high in height, large in span, and heavy in load. In order to increase the bearing capacity and control deflection and cracks, prestressing construction technology is adopted; Tensioning method, one end of the wire rope needs to be anchored, and different construction techniques need to be applied for bonded prestressed tendons and unbonded prestressed tendons. All of them use centralized anchoring, which will cause concentrated stress, affect the service life of high-rise buildings, and may cause potential safety risks. Contents of the invention [0003] The purpose of the present invention is: in view of the existing prestressed tendons with bonded or unbonded prestressed tendons in the prior art, the fixed ends ad...
