Prefabricated hollow column and superposed beam connecting structure and construction method

Abstract

The invention relates to a prefabricated hollow column and superposed beam connecting structure and a construction method. The prefabricated hollow column and superposed beam connecting structure comprises a hollow column and a superposed beam, wherein the hollow column and the superposed beam are connected with each other; a beam hole is reserved in the beam and column junction area of the hollowcolumn according to the size of the superposed beam, and hoop ribs of the hollow column in the beam hole are normally arranged; bottom longitudinal stressed rebars and beam side constructed ribs or twisted ribs of the superposed beam are mechanically connected or connected in a binding mode within a 1 / 3 superposed beam support seat span range outside the hollow column; and upper longitudinal stressed rebars of the superposed beam are mechanically connected or connected in the binding mode within a 1 / 3 superposed beam midspan range outside the hollow column. The construction method of the rebars in the beam and column core area of the prefabricated hollow column of prefabricated concrete has the advantages of high construction speed and high installation efficiency and conforms to the development trend of assembled and standardized building industrialization.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a prefabricated hollow column composite beam connection structure and a construction method. Background technique [0002] At present, the development of the prefabricated frame structure system is becoming mature. The prefabricated column components in the conventional prefabricated concrete frame structure are too heavy, and it is extremely difficult to bind the steel bars in the core area of ​​the beam and column and support the formwork. The quality of the concrete pouring construction is not easy to guarantee, and the degree of industrialization is low. . Contents of the invention [0003] The purpose of the present invention includes, for example, to provide a prefabricated hollow column composite beam connection structure and construction method, which not only solves the problem of the bottom and upper longitudinal stress reinforcement of the composite ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention includes, for example, to provide a prefabricated hollow column composite beam connection structure and construction method, which not only solves the problem of the bottom and upper longitudinal stress reinforcement of the composite beam due to the normal setting of stirrups in the core area of ​​the beam column. And the problem that the beam side structural reinforcement or button reinforcement cannot be installed, and solves the problem of supporting formwork in the core area of ​​​​the beam and column without setting a beam nest in the hollow column range. The method has the advantages of fast construction speed, high installation efficiency, and conforms to the development trend of assembly and standardized construction industrialization.
