Problems solved by technology
However, in order to achieve "equivalent to cast-in-place", this type of prefabricated frame usually needs to take more cumbersome construction measures at the joints of the nodes, which makes the engineering cost and design and construction time-consuming more than the traditional cast-in-place frame, and does not fully realize the "applicable and economical" , green, and beautiful" prefabricated structure requirements

The invention relates to the field of building technology, in particular to an assembled frame beam-column node with adjustable multi-level performance, including a connection assembly, a friction hinge assembly and a limit assembly, the two connection assemblies are respectively used to connect beam ends and column ends, and the friction hinge The two ends of the component are respectively connected with two connecting components so that the two connecting components can rotate relatively in the rotation plane. The two connecting components are limited in the direction of rotation of the components. The present invention is used in the prefabricated frame structure system. When the structure encounters different types and levels of disasters, it can provide multi-level adjustable stiffness, bearing capacity and deformation capacity according to the structural deformation state, and provide the required performance parameters. The characteristics of quick repair after the structure earthquake can realize high-performance prefabricated structure.
Description
technical field [0001] The invention relates to the field of building technology, in particular to an assembled frame beam-column node with adjustable multi-level performance. Background technique [0002] Among all kinds of prefabricated structures, prefabricated concrete frame structures are widely used, and are usually used in various hospitals, school buildings, office buildings, residences and other buildings with important functions in cities. The seismic safety of prefabricated frame buildings is the One of the key factors affecting the comprehensive disaster resilience of cities. In prefabricated frame structures, the performance of prefabricated beam-column connections has a significant impact on the overall structural performance and seismic safety. The characteristic of the equivalent cast-in-place beam-column joint in the related art is that its performance requirement is equal to that of the cast-in-place concrete beam-column joint, and the analysis and design ...
