Embodiment Construction

[0017] The structure, processing and use of the present invention will be further described below in conjunction with the accompanying drawings.

[0018] figure 1 Shown is the overall schematic diagram of the present invention. The specific construction steps are as follows:

[0019] 1) Reinforced concrete beam-column joint units are prefabricated in the factory (such as figure 1 Shown are upper and lower units), and the reinforced concrete beam-column node unit includes a prefabricated reinforced concrete beam 1 and a prefabricated reinforced concrete column 2 . A long circular tunnel 3 is reserved in the prefabricated reinforced concrete column 2 . The end of the prefabricated reinforced concrete column 2 is covered with a steel sleeve 4, and the four inner sides of the steel sleeve 4 are provided with stud connectors 5, and the prefabricated reinforced concrete column 2 and the steel sleeve 4 are connected by pouring concrete through the stud connector 5 into a whole. ...

Abstract

The invention relates to a field connecting method among prefabricated reinforced concrete columns, facilitates to realize a novel prefabricated assembly technology mode of node factory prefabrication-beam column field connection, prevents the scene casting of concrete in a beam column node area, and belongs to the technical field of structural engineering. The method comprises the following steps: through long round hole ways are reserved in the prefabricated reinforced concrete columns; the ends are coated with steel sleeves; beam column nodes serve as a whole prefabricated unit for lifting on the scene; the steel sleeves at the ends of the upper and lower layers of columns are connected through butt welding joints after being aligned; and finally, concrete is cast in the round hole ways and cavities of the steel sleeves. The method has the advantages of simple configuration, convenience for construction, high field installation speed, low concrete wet operation load, little influence on surrounding environments, excellent stress performance, reliable force transfer, prevention of exposure of concrete cracks in connection areas by means of the steel sleeves, provision of restraint effect, convenience for material taking and processing, low use level of steels and good economical efficiency.

Description

technical field [0001] The invention relates to an on-site connection method between prefabricated reinforced concrete columns, belonging to the technical field of structural engineering. Background technique [0002] At present, the scale of engineering construction in my country is very large, but the technical level needs to be improved. Among them, the low level of industrialization is one of the key bottlenecks restricting the improvement of my country's construction industry. The development of structural prefabrication and assembly technology is an important way to improve the level of construction industrialization. Reinforced concrete frame structure is one of the most widely used structural forms, and its prefabricated assembly technology has received extensive attention in recent years. The existing prefabricated assembly technology is mainly for reinforced concrete beams and reinforced concrete columns. During construction, the beam-column components are prefabri...
