A bending-shear separated prefabricated frame column and its construction method

Abstract

The invention discloses a bending and shearing separation type prefabricated assembly-type frame column and a construction method thereof. A column section comprises an upper column section body and alower column section body; the spliced position of the column section bodies is located at a bending moment anti-bending point; a horizontal bottom-end steel seal plate is pre-embedded in the bottomend face of the column section, and a downwards externally-protruding shear key is arranged on the lower surface of the bottom-end steel seal plate; a horizontal top-end steel seal plate is pre-embedded in the top end face of the column section, and a downwards internally-sunken shear key groove which is matched with the shear key is formed in the upper surface of the top-end steel seal plate; thebottom-end steel seal plate and the top-end steel seal plate are tightly attached; the shear key is downwards clamped into the shear key groove, and the shear key and the shear key groove are tightlymatched; and the top-end steel seal plate and the bottom-end steel seal plate are fixedly connected into a whole through an anti-bending piece. According to the bending and shearing separation type prefabricated assembly-type frame column, bending and shearing members are separated, the vertical bearing capacity of the frame column can be guaranteed, the anti-seismic requirement is met, the structure is simple, processing, construction and mounting are convenient, and meanwhile the economically feasible performance cost ratio is high.

Description

technical field [0001] The invention relates to a vertical member of a frame structure, in particular to a prefabricated frame column for bending-shear separation and a construction method thereof. Background technique [0002] Due to the impetus of economic development and technological progress, as well as the huge demand for housing in the process of urbanization, labor shortage and other limiting factors, the foundation has been laid for the industrialization of housing and the application of prefabricated components. The prefabricated structure is a concrete structure made of prefabricated components as the main component, assembled, connected, and partially cast in place. Prefabricated components have high construction efficiency, low cost, and conform to the green construction principle of "four sections and one environmental protection", which is the development direction of the civil engineering field. [0003] At present, the prefabricated vertical member frame co...
