Prefabricated friction-energy-consuming self-resetting baffle communication node

Abstract

Provided in the invention is a prefabricated friction-energy-consuming self-resetting baffle communication node comprising node-domain rectangular steel tube concrete columns. A first baffle plate anda second baffle plate are arranged at the upper ends and the lower ends of the node-domain rectangular steel tube concrete columns respectively; and extending arms are arranged around the first baffle plate and the second baffle plate; H-shaped steel beams are arranged between the extending arms arranged in parallel between the first baffle plate and the second baffle plate; rubber gaskets are arranged between upper and lower flanges of the H-shaped steel beams and the extending arms; and the H-shaped steel beams and the node-domain rectangular steel tube concrete columns that are arranged inopposite are connected by high-strength prestressed steel strands with cables. The flange-included node-domain rectangular steel tube concrete columns are arranged at the top of the first baffle plate and the bottom of the second baffle plate. According to the prefabricated friction-energy-consuming self-resetting baffle communication node, the installation error is reduced; the prefabrication ofthe factory is realized; the node quality is improved; the node has the self-resetting function; the post-earthquake maintenance costs are lowered; and the anti-seismic capacity is enhanced.

Description

technical field [0001] The invention belongs to the technical field of building structure engineering, and in particular relates to an assembly type frictional energy consumption self-reset partition plate penetration node. Background technique [0002] my country is located in an earthquake-prone area. The current "Code for Seismic Resistance of Building Structures" [1] sets the three levels of fortification of "not damaged by small earthquakes, repairable by moderate earthquakes, and not collapsed by major earthquakes" to achieve building structures under frequent earthquakes. It is in the elastic working stage under the design earthquake; it enters the elastic-plastic working stage under the design earthquake, and its normal function can be maintained through repair after the earthquake; and it has the necessary anti-collapse performance under the rare earthquake. For existing buildings, once there is excessive residual deformation or the main stress-bearing components suf...

AI Technical Summary

Problems solved by technology

[0004] With the rapid development of my country's economy, the connection structure of rectangular reinforced concrete columns and steel beams has been applied in high-rise buildings and super high-rise buildings, but there is still a large amount of on-site welding work, and on-site welding of partitions and connecting plates and rectangular columns is required. There is no guarantee; when an earthquake or strong vibration occurs, the structure is easily damaged, it is difficult to repair, and the repair cost is also high
