A non-damage adjustable stiffness prefabricated frame beam-column connection structure and its construction method

Abstract

The invention discloses a non-damage stiffness-adjustable prefabricated frame beam and column connection structure and a construction method thereof. The non-damage stiffness-adjustable prefabricatedframe beam and column connection structure comprises a prefabricated reinforced concrete column and a prefabricated beam which are connected; a pin joint device which enables the beam end of the prefabricated beam to vertically and freely rotate relative to the prefabricated column is fixed between the center of the beam end face of the prefabricated beam and the prefabricated column; the pin joint device is a vertical shear-resisting connecting lug plate set, and a pin joint shaft is arranged on the shear-resisting connecting lug plate set in a penetrating mode; and the pin joint shaft is located in the middle of a reserved gap between the reinforced concrete column and the prefabricated beam. Compared with the ideas of bending and shearing separation, strong shearing and weak bending, and bending shearing elasticity, a pre-embedded piece capable of being accurately positioned is prefabricated in a factory through a fabricated structure, processing is convenient, on-site mounting of the structure is easy and convenient, the mounting efficiency is improved, the economic feasibility is achieved, and the performance cost ratio is high; and structural steel bars are completely disconnected, the steel bar overlapping problem is avoided, and the advantage of convenient construction is achieved in the real sense.

Description

technical field [0001] The invention relates to a frame structure beam-column connection structure, in particular to a prefabricated frame beam-column connection with adjustable stiffness without damage and a construction method thereof. Background technique [0002] Due to the promotion of economic development and technological progress, as well as the huge housing demand and labor shortage in the process of urbanization, 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. It has high construction efficiency, low cost, and conforms to the green construction principle of "four sections and one environmental protection". It is the development direction of the civil engineering field. According to Article 6.1.1 of JGJ1-2014 Technical Regulations for Prefabri...
