Problems solved by technology

[0007] However, when erecting prefabricated beams, it is necessary to make some supports on the edge of the prefabricated columns. When connecting the prefabricated upper columns and the prefabricated lower columns, it is time-consuming to locate the steel bars at the same position of the prefabricated beams.
However, there are many disadvantages in the existing method, such as: the method of making corbels at the side of the column, this method has a large amount of construction work and is uneconomical; set the legs at the bottom of the prefabricated upper column to support the prefabricated upper column, in addition, this method The method is time-consuming in the process of positioning the prefabricated upper column

Abstract

The invention discloses a prefabricated beam-column joint and a construction method thereof. The prefabricated beam-column joint comprises a prefabricated beam, a prefabricated column, a beam connecting rib and a joint rebar sleeve; the prefabricated column comprises a prefabricated upper column and a prefabricated lower column; the prefabricated beam is divided into two sections, and one ends ofthe two sections of prefabricated beam bodies are correspondingly arranged between the prefabricated upper column and the prefabricated lower column; and a joint area is formed between the prefabricated upper column, the prefabricated lower column and the two sections of prefabricated beam bodies, and the joint area is filled with concrete to form a joint section. According to the prefabricated beam-column joint and the construction method thereof, pre-embedded U-steel is arranged in the prefabricated beam so that the prefabricated beam can be directly erected on the prefabricated lower columnduring construction, and the construction speed of the structure is increased; and brackets or other structures are not required to be manufactured at the edge of the column to conveniently erect theprefabricated beam on the prefabricated lower column, so that the construction process is simplified.

Description

technical field [0001] The invention relates to a prefabricated building structure beam-column joint and a construction method thereof, in particular to a prefabricated beam-column joint and a construction method thereof. Background technique [0002] Precast concrete structures have the advantages of saving materials, speeding up construction progress, improving the quality of components, energy saving and environmental protection, etc. Precast concrete structures have broad development prospects. But as the beam-column joint, one of the important parts in the prefabricated structure, how to make the prefabricated beam-column joint to make it a whole. Many technical and construction problems have not been well resolved, and have become important issues restricting the promotion of prefabricated building structures. [0003] The existing methods for making prefabricated beam-column joints include: steel bars are connected by sleeve extrusion outside the joint area, joint ca...
