Shock isolation device of small low-rise building foundation

Abstract

A shock isolation device of a small low-rise building foundation comprises a building bearing plate (1), a building side baffle (2), secure supports (3), a foundation side baffle (4), tension springs (5), balls (6), ball connecting cages (7), a foundation bearing plate (8), a compression spring baffle (9) and compression springs (10). Each secure support (3) comprises a nut (3-1), a main connecting pin (3-2), connecting supporting plates (3-3), connecting bearing blocks (3-4), auxiliary connecting pins (3-5) and a secure rod (3-6). Each ball connecting cage (7) comprises upper rotating ball rings (7-1), rotating balls (7-2), connecting ribs (7-3), middle rotating ball rings (7-4) and lower rotating ball rings (7-5). The shock isolation device is ingenious in structure, easy to produce in a standardized mode, low in cost, obvious in shock isolating effect and suitable for being applied to the small low-rise building foundation. Furthermore, the secure supports (3) are applied, the stability of a body building is maintained when slight external force acts on the body building, and the discomfort feelings such dizziness of people can be avoided.

Description

technical field [0001] The invention relates to a building foundation shock-isolation device, in particular to a small-sized low-rise building foundation shock-isolation device. Background technique [0002] Seismological research proves that the propagation modes of seismic waves are mainly divided into longitudinal waves and transverse waves. The longitudinal waves are propulsive waves, which cause the ground to vibrate up and down, and are less destructive; the shear waves are shear waves, which cause the ground to vibrate back and forth, left and right, and are more destructive. ;In seismically active areas, earthquakes occur frequently, and the anti-seismic performance of buildings with traditional structures is low. Especially in rural areas and small towns in my country, residents generally build small low-rise buildings by themselves, and construction cost control is often the first consideration. Ordinary families Rarely adopt expensive anti-seismic structures; theref...
