Construction method for high-rise concrete structure

Abstract

The invention relates to a construction method for a high-rise concrete structure. The method comprises the following steps of: (1) concrete column construction; (2) concrete beam construction: mounting a high-strength prestressed concrete beam duct piece prefabricated in a factory for prefabrication by using a tower crane, mounting a reinforcement cage processed in a factory in the high-strength prestressed concrete beam duct piece in sections, pouring concrete by using a concrete pump truck, and forming a concrete beam after maintenance is finished; (3) concrete slab construction: mounting a corrugated sheet on the concrete beam, laying a board bar-mat reinforcement mesh processed in a processing factory, then pouring concrete by using the concrete pump truck, and forming the concrete slab after the maintenance is finished, thus the construction of the first layer structure of the concrete structure is finished; and repeatedly carrying out the steps (1)-(3) to perform the construction of the second layer structure of the concrete structure until the construction of the whole high-rise concrete structure is finished. The method in the invention is simple and practicable, does not need to support a scaffold and a template, effectively shortens the construction time, improves the construction efficiency, lowers the construction cost, improves the construction quality, and is a safe and reliable construction method for the high-rise concrete structure.

Description

technical field [0001] The invention belongs to the field of high-rise concrete structures, in particular to a construction method for high-rise concrete structures. Background technique [0002] High-rise concrete structures are generally divided into several layers, and each layer is constructed with cast-in-place concrete columns, concrete beams, and concrete slabs. During the construction process, formwork systems and support systems need to be set up layer by layer. The construction technology is mainly (1) steel bar processing (2) steel bar installation; (3) scaffolding; (4) formwork support; (5) pouring concrete; Larger potential safety hazards, and the appearance quality of the product is difficult to guarantee. However, the traditional prefabricated component assembly construction has been eliminated by the market because the main structure formed cannot guarantee to meet the seismic requirements.
