Beam-end adjustable combined energy dissipation connection assembly of assembly type concrete frame

Abstract

The invention provides a beam-end adjustable combined energy dissipation connection assembly of an assembly type concrete frame. The connection assembly is arranged on the upper side and / or the lower side of the beam end of a beam-column connection of the assembly type concrete frame structure. The connection assembly comprises a column-direction adjustable combined joint (1), a core energy dissipation rod (2), a beam-direction fastening combined cap (3) and a constraint system (4). The adjustable combined energy dissipation connection assembly is made of metal material, and the core energy dissipation rod (2) is arranged in a post-cast tongue-and-groove, and is reliably connected with the tip thread of an in-column anchor bar through the column-direction adjustable combined joint (1). The application of the energy dissipation connection assembly is in accordance with the requirements of the development of building industrialization and has the advantages of simple structure, reliable force transmission and fast installation; by adoption of the energy dissipation connection assembly, the joint ductility is good, the energy dissipation capability is strong, and the assembly can be easily replaced after an earthquake.

Description

technical field [0001] The invention belongs to the field of construction engineering and relates to a prefabricated concrete frame structure, in particular to an adjustable combined energy-dissipating connection component of a prefabricated concrete frame. Background technique [0002] In recent decades, prefabricated concrete structures have been more and more favored by engineers due to their characteristics of industrial production and prefabricated construction, and have been widely used and developed rapidly. 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 countries and regions such as China, the practice of adding ductile energy-dissipating components to prefabricated structures has become increasingly mature, and the use of assemb...

Problems solved by technology

Even if various measures are taken to ensure the dimensional accuracy of the components during the manufacturing process, the dimensional errors of the components and the position errors of the components (such as steel bars) in the components are still inevitable; on the other hand, in order to ensure the smooth progress of the assembly, the There must be a certain degree of clearance between them to avoid collisions during assembly, and these clearances also make there are inevitable length errors between components during installation
