Embodiment Construction

[0037] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0038] The technical problems addressed by the present invention are as follows:

[0039] 1) The structure of the connecting nodes is the key to the seismic performance of the prefabricated concrete frame structure. The components of the prefabricated concrete structure are generally joined at the joints, so that the performance of the connection is particularly important in the prefabricated concrete structure. The connection nodes are the necessary channels for the internal force transmission between components. Under strong earthquakes, the internal force borne by the beam-column joint connection is relatively large, so plastic deformation is more likely to occur. After the accumulation of plastic damage, it is easy to fail and fracture, resulting in the loss of structural integrity.

[0040] 2) The connection construction of joints is a key...

Abstract

The invention provides a replaceable energy consumption connecting assembly for connecting a fabricated frame beam column. According to the technical scheme, a replaceable energy consumption assembly is arranged at the connecting position of the fabricated frame beam column and consists of an energy consumption steel rod, a constraint part and a connecting part, one end of the replaceable energy consumption assembly is connected with a node anchor steel bar embedded into the column, and the other end of the replaceable energy consumption assembly is connected with a beam-end longitudinal steel bar embedded into a beam. Under an earthquake effect, the energy consumption steel rod yields prior to other members and parts and utilizes plastic hysteresis to consume earthquake energy. The replaceable energy consumption connecting assembly is used for connecting the fabricated frame beam column, can induce the plastic damage of the structure in a middle earthquake and a large earthquake to be concentrated on the energy consumption steel rod, the damage of abeam column member can be avoided while the seismic ductility of the structure is improved, and the structure can be rapidly repaired after the earthquake in a simple energy consumption part changing mode, so that the structure repair efficiency after the earthquake is remarkably improved. The application of the replaceable energy consumption connecting assembly meets the industrialization development requirements of buildings.

Description

technical field [0001] The invention belongs to the field of construction engineering and relates to an assembled concrete frame structure, in particular to a replaceable energy-consuming connection assembly applied to the beam-column connection of the assembled frame and a construction method thereof. Background technique [0002] In recent decades, prefabricated concrete structures have been favored by engineers more and more due to their characteristics of industrial production and prefabricated construction, and have been widely used and developed rapidly all over the world. With the in-depth study of performance-based seismic design theory, people have higher and higher requirements for the repairability of structures after earthquakes, and the research and application of high-ductility energy-dissipating components have received more and more attention. In developed countries and regions such as China, the practice of adding ductile energy-dissipating components to pre...
