Abstract

The invention provides a high-performance steel frame shock-absorption support. The high-performance steel frame shock-absorption support mainly comprises a third fixing plate and a support base body,the third fixing plate is located on the support base body, the support base body comprises a horizontal seismic-isolation base body and a vertical seismic-isolation base body, the horizontal seismic-isolation base body comprises a first fixing plate, a second fixing plate, a lead body and a buffer sleeve, a seismic-isolation body is arranged between the first fixing plate and the second fixing plate, the lead body vertically penetrates through the middles of the first fixing plate, the second fixing plate and the seismic-isolation body, the buffer sleeve is arranged on the outer wall of thelead body in a sleeving mode, the vertical seismic-isolation base body is fixed to the upper part of the second fixing plate and comprises elastic parts and a guiding part, the guiding part is locatedin the middle of the vertical seismic-isolation base body, a guiding rod is vertically arranged in a guiding area, and supporting rods are arranged on the vertical left side and the vertical right side of the guiding rod at equal distances correspondingly. The shock attenuation rate can be increased, the anti-seismic effect can be improved, and the quite high energy absorption capability is achieved.

Description

technical field [0001] The invention belongs to the technical field of building structures, and in particular relates to a high-performance steel frame damping support. Background technique [0002] Seismic isolation bearing is a kind of seismic isolation (vibration) technology developed in recent years for the bottom of building structures. Its feature is to effectively isolate the horizontal seismic force from being transmitted to the superstructure through the foundation, so as to reduce the level of the superstructure. Vibrations thus effectively protect the superstructure. The existing products are mainly lead-core rubber shock-isolation bearings. A wide variety of seismic isolation bearing products have been widely used in multi- and high-rise isolation structures. Although some breakthroughs have been made in the study of multi-dimensional earthquakes, they are rarely applied in practice. At present, the theoretical level that is more maturely applied to the calcula...

Problems solved by technology

Although some breakthroughs have been made in the study of multi-dimensional earthquakes, they are rarely applied in practice. At present, the theoretical level that is more maturely applied to the calculation and analysis of earthquakes in actual engineering structures has reached three-dimensional, so the seismic isolation research for three-dimensional earthquakes of structures is particularly important.

Under the three-dimensional earthquake, due to the conflict between the vertical stiffness requirements of the building structure and the vertical isolation, there are currently few devices for vertical isolation

However, the mechanical performance test results of laminated rubber bearings by scholars from New Zealand, Japan, China and the United States all show that the torsional ability of laminated rubber bearings is still very weak.

Applying laminated rubber bearings to the above-mentioned irregular structures is still difficult to solve the problem of excessive torsional deformation of the upper structure, and what is even more dangerous is that the torsional deformation of the upper structure is transmitted to the rubber bearings with weak torsion resistance, which will affect the The rubber bearings cause fatal damage, aggravating and reducing the overall seismic and torsional capabilities of the structure
