Abstract

The invention discloses a prefabricated concrete beam-column joint using medium-strength prestressed tendons. The joint comprising a prefabricated concrete beam, a prefabricated concrete column, medium-strength prestressed tendons, a joint area post-cast section, beam-top common stressed rebars and intra-column vertical rebars. The bottom of the beam is provided with only the medium-strength prestressed bars that extend out of the beam end and are bent up after passing through the midline of the prefabricated column to form hooks, reliably anchored to a joint core area, and the prefabricated concrete beam-column joint is formed with the prefabricated concrete beam and column through post-cast concrete. The invention reduces production and construction difficulty, decreases the sectional height and steel usage of the prefabricated concrete beam and ensures integrity and aseismic performance of the beam-column joint.

Description

technical field [0001] The invention relates to a prefabricated concrete beam-column node connection structure using medium-strength prestressed tendons, and belongs to the technical field of civil engineering prefabricated concrete structures. Background technique [0002] The frame structure is mainly constructed of beams, columns and beam-column joints, which is the most widely used structural form in construction engineering. The prefabricated prestressed concrete assembled monolithic frame structure meets the requirements of "building industrialization, housing industrialization" and green building. This type of structural system has the advantages of fast construction speed, low environmental pollution, guaranteed quality, and good durability. features. [0003] The core technology of precast prestressed concrete assembly integral frame structure is the joint connection structure form of precast concrete beams and precast concrete columns, and its quality directly af...
