A prefabricated concrete structure beam-column connection node, connection method and repair method

Abstract

The invention discloses a prefabricated concrete structure beam-column connection node, a connection method and a repair method, wherein the prefabricated concrete structure beam-column connection node includes a joint plate, prefabricated beams connected to the left and right sides of the joint plate, and an upper layer connected to the top of the joint plate The prefabricated column and the lower prefabricated column connected to the lower end of the gusset plate; connecting blocks and grooved joints are arranged between the gusset plate and the prefabricated beam; the gusset plate, the connecting block and the grooved joint are connected as a whole through main steel strands. The beam-column connection node of the prefabricated concrete structure of the present invention has the characteristics of self-resetting, and the residual deformation after the earthquake is small, so as to ensure that the structure can quickly recover its building function after the earthquake. At the same time, the damage of the structure is limited to the connecting blocks that can be easily replaced or repaired, making it quick and easy to repair after the earthquake. In addition, the structure is all composed of detachable parts, and the sustainable development performance of the building can be improved through the convenient disassembly and recycling of prefabricated components.

Description

technical field [0001] The invention is applicable to the technical field of civil engineering, and relates to a beam-column connection node and method of a prefabricated concrete structure. Background technique [0002] Since 2011, when the State Council clearly stated "actively promote the industrialization of construction", the state has repeatedly issued policies to promote the industrialization of construction. Under the great attention of the Party Central Committee and the State Council, my country's construction industry has begun to develop in the direction of greening, industrialization, and informatization. The industrialization of new buildings focusing on prefabricated buildings is the focus of current development. Among them, the prefabricated concrete frame structure is one of the most common and widely used prefabricated structural systems, which has the advantages of reliable function, high durability, easy repair, rapid construction, reasonable cost and con...
