Earth surface shock isolation band with low-frequency surface wave band gap and implementation method of earth surface shock isolation band

Abstract

The invention discloses an earth surface shock isolation band with a low-frequency surface wave band gap and an implementation method of the earth surface shock isolation band. The earth surface shockisolation band comprises a soil layer, the soil layer is of a frame structure and surrounds the exterior of a building, and shock isolation units which are vertically and upwards distributed in a two-dimensional lattice periodic arrangement mode are arranged on the surface of the soil layer; each shock isolation unit comprises a bottom plate fixed to the soil layer and a vertical rod fixed to themiddle of the upper surface of the bottom plate, and the same distance is reserved between the side edges of every two adjacent bottom plates; and the bottom plates are matched with two-dimensional crystal lattices in shape, and each bottom plate is located in the center of the corresponding two-dimensional crystal lattice. According to the earth surface shock isolation band, the structure is simple, manufacturing is easy, the wide band gap exists, attenuation of seismic surface waves is achieved, and the shock isolation band can be designed in a surface area outside the building according toan inherent frequency value of a target building.

Description

technical field [0001] The invention relates to the technical field of anti-seismic structures, in particular to a surface isolation belt with a low-frequency surface wave band gap and an implementation method thereof. Background technique [0002] The main threat of earthquakes to the safety of life and property is the collapse of buildings caused by earthquakes, especially the destruction of some important buildings and industrial facilities will bring irreparable disasters and losses, such as nuclear power plants and ancient buildings. The current anti-seismic isolation measures for buildings are mainly to install anti-seismic brackets at the bottom of the building, but this type of anti-vibration device is expensive and has limited anti-seismic capability, and this anti-seismic measure is powerless to ancient buildings with important cultural significance.

Problems solved by technology

The current anti-seismic isolation measures for buildings are mainly to install anti-seismic brackets at the bottom of the building, but this type of anti-vibration device is expensive and has limited anti-seismic capacity, and this anti-seismic measure is powerless for ancient buildings with important cultural significance

[0003] Most of the existing shock absorption methods are to fill the building foundation with shock-absorbing materials, which cannot make full use of the use area above the ground surface

Moreover, most of the shock-absorbing materials in the foundation are filled with solid materials, which generally require a large amount, causing a lot of inconvenience in installation and transportation, and the band gap width is small, and the shock-absorbing effect is poor, so it is difficult to widely popularize and apply.
