Abstract

The invention relates to the technical field of buildings, and particularly relates to a hybrid connection joint of a fabricated concrete column and an H-shaped steel beam. According to the technical scheme, the hybrid connection joint of the fabricated concrete column and the H-shaped steel beam comprises the prefabricated concrete column, the H-shaped steel beam, a first connecting piece, second connecting pieces, a third connecting piece and high-strength bolt pairs; the prefabricated concrete column is provided with three sets of embedded bolt rods, the first connecting piece and the third connecting piece are fixedly mounted on the embedded bolt rods, and the two second connecting pieces are arranged on the upper side and the lower side of the first connecting piece correspondingly and fixedly mounted on the embedded bolt rods; and the H-shaped steel beam is connected with the first connecting piece, the second connecting pieces and the third connecting piece through the high-strength bolt pairs. According to the hybrid connection joint of the fabricated concrete column and the H-shaped steel beam, the technical problems that the connection strength of the concrete column and the steel beam is poor, the rigidity is small, the energy dissipation capacity is poor, and a steel structure joint is prone to brittle fracture damage under the earthquake action are solved.

Description

technical field [0001] The invention relates to the field of building technology, in particular to a hybrid connection node of an assembled concrete column and an H-shaped steel beam. Background technique [0002] Prefabricated buildings refer to buildings in which all parts of the building are prefabricated in the factory and then transported to the construction site for assembly, which omits concrete pouring and welding. Prefabricated buildings are more standardized in section size than on-site fabrication. The hybrid structure system can give full play to the respective advantages of concrete and steel, so that the comprehensive performance of the structure is better than that of the traditional concrete structure or steel structure. Therefore, it is easier to realize "strong columns and weak beams, strong joints and weak members, and easy repair after earthquake". [0003] In traditional buildings, the connection between concrete and H-shaped steel beams is to put embe...
