Abstract

The invention discloses a semi-prefabricated reinforced concrete column joint unit and application thereof, and belongs to the technical field of buildings and structural engineering. The designed semi-prefabricated reinforced concrete column joint unit is provided with a cross-shaped steel beam in advance, I-shaped steel for supporting and strengthening is arranged at an upper flange and a lowerflange, so that the cross-shaped steel beam can act as a lateral displacement resistance frame, side displacement stability during mounting is ensured, and the mounting speed is accelerated; and between columns, a prefabricated inter-column connecting part is used for connecting with end plates of the upper and lower columns by using bolts, sleeve connection between longitudinal bars is not needed, and a mounting process is more convenient and stable. The designed semi-prefabricated reinforced concrete column joint unit is taken as a semi-prefabricated integral unit, the industrialization degree and modularization degree are higher, and through accessory standardizing of inter-column connection and inter-beam connection, the semi-prefabricated reinforced concrete column joint unit is highin processing efficiency in a factory and is more aligned with a mode of construction industry future industrial development.

Description

technical field [0001] The invention relates to a semi-prefabricated reinforced concrete column node unit and its application, and belongs to the technical field of architecture and structural engineering. Background technique [0002] In the construction process, the operation of cast-in-place concrete technology has been widely used in the development of my country's construction undertakings. In the actual operation process, the development of my country's construction undertakings started relatively late, and the use of foreign advanced technologies and mature processes is very different. It soon spread to China, which promoted the development and application of concrete connection technology in our country. The use of concrete cast-in-place technology in our country has gradually moved towards a better technology after several generations of development and reform. In the actual construction process, the emergence of concrete cast-in-place technology has made valuable co...
