Embodiment 1

[0034] Embodiment 1, the anti-seismic device of the present invention includes multi-stage anti-seismic, which can gradually play an anti-seismic effect. Many bridges have bridge piers 1, and some of the bridge piers 1 are cylindrical, and some are rectangular or other shapes. The device 2 is ring-shaped, and wraps and fixes the bridge pier 1. If the bridge pier 1 is not cylindrical, the gap between the ring-shaped anti-seismic device 2 and the bridge pier 1 is filled with reinforced concrete of the same material as the bridge pier. The part of the bridge pier 1 is placed above the ground, and the part is placed below the ground, and the anti-seismic device 2 of the present invention is arranged on the outside of the bridge pier 1 below the ground, and the anti-seismic device 2 of the present invention is the same as the depth below the ground of the bridge pier 1 .

[0035] The anti-seismic device 2 includes an annular shell 3. The middle of the annular shell 3 is a bridge pi...

Embodiment 2

[0039] Embodiment two, on the basis of embodiment one, the physical anti-seismic bin 5 is divided into a first-level physical anti-seismic bin 35, a second-level physical anti-seismic bin 36, and a third-level physical anti-seismic bin 37 through two annular baffles 4. The baffle plate 4 has the same name as the plurality of annular baffle plates 4 in the first embodiment, because there are multiple annular baffle plates 4 in the first embodiment, and the annular baffle plate 4 here is also one of the multiple ones. Level physical anti-seismic chamber 35 is filled with carbon fiber material. Carbon fiber is mainly compounded with resin, metal, ceramics and other substrates to make structural materials. Carbon fiber reinforced epoxy resin composite material has comprehensive indicators such as specific strength and specific modulus in the existing It is the highest among structural materials. In areas with strict requirements such as density, stiffness, and weight, carbon fiber ...

Embodiment 3

[0040] Embodiment three, on the basis of embodiment one, if the first rack 14 contacts the ground and is not placed below the ground, a third spring 38 is connected to the lower end of the first rack 14, and a matching spring 38 is connected to the lower end of the third spring 38. Weight 39, because the longitudinal wave of the earthquake vibrates the first rack 14 and the ring baffle 4 when the amplitude of the device is up and down, if the amplitude is the same, then the first rack 14 and the ring baffle 4 move synchronously, the second A rack 14 also does not have a displacement movement, but in fact the body wave of the earthquake is an irregular movement. After vibrating several times, the first rack 14 and the annular baffle 4 must no longer move synchronously. It is more guaranteed that the first rack 14 is out of sync with the annular baffle plate 4. At the same time, in order to ensure that the first rack 14 can go down normally after it vibrates, the added third spri...

Abstract

The invention relates to a multi-stage anti-seismic bridge device. The multi-stage anti-seismic bridge device effectively solves the problem that existing bridge anti-seismic devices are all designedafter an earthquake acts on a bridge. According to the technical scheme, the multi-stage anti-seismic bridge device comprises an anti-seismic device. The anti-seismic device comprises a physical anti-seismic bin, a first-level anti-seismic bin and a second-level anti-seismic bin, wherein the physical anti-seismic bin is filled with a physical anti-seismic material, and a plurality of first anti-seismic devices uniformly distributed in the circumference are arranged in the first-level anti-seismic bin. A second pulley is coaxially connected with a third gear, a third rack meshes above the thirdgear, and the third rack is in contact with an annular baffle arranged at the front end. The multi-stage anti-seismic bridge device has an ingenious structure, the upper and lower amplitudes generated by seismic longitudinal wave are converted into transverse acting force, and the transverse acting force is used for carrying out buffering and energy dissipation on opposite acting force of an annular baffle plate, and the force of seismic wave transmission is weakened in the whole anti-seismic device according to the prolonged time and the action of a spring.

Description

technical field [0001] The invention relates to the field of bridge anti-seismic technology, in particular to a multi-stage anti-seismic bridge device. Background technique [0002] The concept of bridge anti-seismic is a technical measure taken to avoid bridge damage from earthquakes. The damage to bridges caused by earthquakes is mainly caused by ground damage and bridge damage. Among them, the surface damage includes ground fissures, landslides, landslides, bank slope slippage, and sand liquefaction. Ground fissures can cause bridge span shortening, elongation or pier subsidence. In steep mountainous areas or sandy soil and soft clay river banks, bridges can be damaged due to landslides, bank slope sliding and rock rolling caused by strong earthquakes. In the shallow saturated loose sandy soil, the earthquake action will easily cause the sandy soil to liquefy, causing the bridge to sink suddenly or unevenly, or even topple the bridge. Earthquakes often cause bank slope...
