Prefabricated concrete structure connecting method

Abstract

The invention relates to a prefabricated concrete structure connecting method, which comprises the following steps that (1) a steel bar internal force converter is manufactured; (2) a steel bar is connected with one end of the steel bar internal force converter; (3) the steel bar and the steel bar internal force converter are positioned in a component according to design requirements; an anti-shearing groove is formed in the connecting end surface of the component; and concrete is cast to form a prefabricated component; (4) a connecting screw bolt between the steel bar internal force converters is selected; (5) when the manufacturing of the prefabricated components is completed and the prefabricated components are conveyed to a construction site to be installed, the connecting end surfaces of the two prefabricated components are attached and aligned; and at the time, the end surfaces of the steel bar internal force converters on the two prefabricated components are all attached and aligned; and (6) the screw bolt passes through a screw bolt connecting hole formed in each steel bar internal force converter and is tightened to the preset torque; and after all steel bar internal force converters are sequentially connected through the screw bolt, the two prefabricated components are also connected together. The invention provides the prefabricated concrete structure connecting method with the advantages that the process is simplified, and the reliability is high.

Description

Technical field [0001] The invention relates to a method for connecting an assembled concrete structure. Background technique [0002] The industrialization of the construction industry has become the direction of the development of my country's construction industry. In the process of industrialization of the construction industry, it has become inevitable to transform the current situation of buildings from on-site construction to factory-based prefabrication and on-site assembly. At present, most of the buildings in my country are constructed using cast-in-place reinforced concrete technology. With the popularization and application of prefabricated concrete technology, in order to ensure that the structural performance of prefabricated concrete structures is not lower than that of cast-in-place concrete structures, my country has also formulated corresponding technical regulations for concrete structures, including structural design to component prefabrication and on-site con...

Problems solved by technology

[0004] In order to overcome the deficiencies of complex process and poor reliability of the existing prefabricated concrete structure connection methods, the present invention provides a prefabricated concrete structure connection method with simplified process and good reliability, which directly adopts mechanical methods through the steel bar internal force converter Connecting the steel bars, the internal force converter of the steel bars does not affect the thickness of the protective layer of the steel bars, which can reduce the reduction of the concrete protective layer due to the assembly connection; it is also unnecessary to reserve the overhanging connecting steel bars, making the transportation and hoisting of prefabricated components more convenient
