Field connecting method among prefabricated reinforced concrete columns
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.
