Fabricated anti-seismic beam-column connection node structure

Abstract

The invention provides a fabricated anti-seismic beam-column connection node structure. The fabricated anti-seismic beam-column connection node structure comprises fixing columns and cross beams, a cavity is formed in a fixing column, a connecting hole is formed in one side of the cavity, a fixing plate is arranged in the cavity, a connecting block for connecting the fixing plate and a cross beam is arranged at the connecting hole of the cavity, and first damping assemblies is arranged between the connecting block and the cross beam. Supporting assemblies connected between the connecting block and the fixing column is arranged below the connecting block, and second damping assemblies is arranged between a supporting assembly and the fixing column. According to the fabricated anti-seismic beam-column connection node structure, the first damping assemblies are extruded to contract, so that part of earthquake energy can be consumed, the vibration influence is relieved, the cross beam can be reset under the action of the first damping assemblies, the supporting assemblies can diffuse thrust to the fixing columns, and the second damping assemblies effectively relieve vibration between the cross beam and the fixing columns; therefore, the earthquake energy can be diffused and reduced step by step, damage caused by earthquakes is reduced, and the anti-seismic strength of a beam-column connection node is improved.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to an assembled anti-seismic beam-column connection node structure. Background technique [0002] The construction industry is one of the pillar industries of my country's national economy, but my country's construction industry is still a labor-intensive traditional industry dominated by cast-in-place construction methods. With the development of my country's economy, the traditional extensive development model is no longer suitable my country's demand for high-quality construction products, my country needs to vigorously develop prefabricated buildings. As a new energy-saving and environmentally friendly building system, prefabricated steel structure buildings are known as one of the "green buildings" in the 21st century, and are the main development direction for promoting prefabricated buildings in my country. [0003] Due to the fixed structural form of the existing...
