Abstract

An earthquake-resistant facility for building or bridge features that a ball is arranged between two opposite concave rounded surfaces and when the bottom body with concave rounded surface vibrates, the ball rolls in both concave rounded surfaces and the top body with concave rounded surface is stationary.

Description

Building, bridge Aseismic device

This invention belongs to building (civilian construction, factory building and highrise building etc.) and bridge (also comprising railroad bridge etc.) in the generation earthquake the stable technical field that exempts from seismic damage takes place particularly can remain intact in the violent earthquake region.

Keep away the earthquake principle: utilize the steel metal ball body two with the concave spherical surface body of the mutual make-up of the identical material of spheroid (recessed spherical surface body belong to the vibrations object be the building foundation part be constitute one with ground the seismic origin just with it the fovea superior spherical surface body of make-up to belong to the fixed object that is not subjected to earthquake effect be building on the basis, the position shape of two mutual make-ups of concave spherical surface body

Image) passive rolling is recessed spherical surface body between the concave spherical surface, during as the vibrations of any direction of occurred level direction, be clipped in this moment that spheroid between the concave spherical surface of two mutual make-up concave spherical surface bodies is simultaneously passive does corresponding and recessed spherical surface body backscrolling, the rolling at this moment of this spheroid is that (this moment, the fovea superior spherical surface body did not produce corresponding horizontal direction or lengthwise movement because of the motion of recessed spherical surface body and spheroid to the concave spherical surface that occurs in two concave spherical surface bodies simultaneously, it belongs to fixed object, i.e. building on the basis.It is two bodies with building on the basis that the building of keeping away earthquake should be looked the basis, promptly be not one each other), when spheroid on recessed spherical surface body concave spherical surface is to be that the passive lowest point that leaves recessed spherical surface body concave spherical surface of spheroid scrolls up when minimum point (position before the passive movement) beginning of concave spherical surface is done horizontal motion (vibrations of horizontal direction) with recessed spherical surface body by the home position, meanwhile spheroid is also rolled downwards by the moving preceding peak (being the position on fovea superior spherical surface body concave spherical surface before spheroid moves) on the fovea superior spherical surface body concave spherical surface of corresponding left-hand thread of spheroid, this moment, spheroid is in height that following concave spherical surface the rises decline degree of depth on the fovea superior spherical surface body concave spherical surface of this spheroid at left-hand thread meanwhile just, be spheroid when on the concave spherical surface of two mutual left-hand threads, doing passive roll its spheroid itself because the motion (by the transverse vibration that laterally seismic wave caused of earthquake) of recessed spherical surface body horizontal direction any direction and in the concave spherical surface rising of recessed spherical surface body, at this moment, fovea superior spherical surface body itself does not but rise along with the rising of spheroid and promptly does the corresponding lengthwise movement that makes progress, its reason is that spheroid is when lower peripheral surface body concave spherical surface rises, but having done equivalent decline on the concave spherical surface of the fovea superior spherical surface body of left-hand thread rolls, therefore, spheroid can not be driven the fovea superior spherical surface body by the rising of self and move upward, descend (i.e. Zhen Dong moment counter motion) as the same by that analogy, clearly with reference to Figure of description I-1, accompanying drawing I-2, accompanying drawing I-3, accompanying drawing I-4, accompanying drawing I-5.

Because seismic wave (comprises longitudinally destruction employing cushioning between basis and building of seismic wave of lateral wave and longitudinal wave one, soft porous class material such as soft rubber or soft polyvinyl chloride plastic etc. play the absorption shock wave and reduce promptly longitudinally that seismic wave intensity can play cushioning effect, longitudinally seismic wave is far away to be lower than laterally seismic wave, do not do a statement herein), has the frequency height, amplitude of vibration is little, the characteristics that energy is big, the reverse landscape motion that laterally is any direction of horizontal direction thus is quite fast and frequent, sometimes be (with seismic wave frequency dependence laterally) finished moment therefore, in the fovea superior spherical surface body on the spheroid is that building on the basis is just more stable, so the building and the bridge that are provided with Aseismic device can not wreck because of earthquake takes place.

Building, bridge Aseismic device design according to above-mentioned principle.

By retrieval, inquiry is not seen this technology of employing as yet at existing building and bridge and pertinent literature thereof.

This invention system adopts equidistant three spheroids and its make-up and by the Aseismic device assembly of the upper and lower concave spherical surface body composition of certain concave surface curvature requirement mutually, the product that can be manufactured on the multiple model of same series according to the payload difference and the spheroid load-bearing position difference of building and bridge is with reference to Figure of description 2-1, accompanying drawing 2-2, accompanying drawing 2-3 and accompanying drawing 2-4.

This invention can guarantee to be provided with the building of Aseismic device and bridge in the violent earthquake region takes place; its building and bridge are excellent; can not wreck because of earthquake; therefore; the people's life, property are protected and ensure; avoided simultaneously giving heavy blow that the people masses in disaster area are brought and the lifelong misery that is difficult to bear because of earthquake disaster.To recovering normal work of the disaster area people and life, all can play active influence.This measure is benefited the nation and the people, and this is the tidemark of this invention.

The advantage of this invention: 1, protected the earthquake-stricken area people's life, property to exempt from injury and loss.2, reduce to reduce the economic loss of bringing to country because of earthquake, simultaneously the production in disaster area to the greatest extent again and the people's operate as normal and life are played a positive role and influence.3, the building that is provided with Aseismic device and bridge are not had all that to influence its compliance strong in either direction vibrations that the former meaning transverse vibration of earthquake takes place is horizontal direction.4, this technology is reliable, cost is low, and product structure is simple, easy construction, avoided in the past for improving the passive traditional method that the Antiseismic building performance strengthens fabric structure intensity (this measure need drop into substantial contribution, and the building cost straight line is risen) relatively.Simultaneously, save a large amount of steel and fund can for country.

Claims

Technical characterictic: utilize spheroid, on the concave spherical surface of the concave spherical surface body of two mutual make-ups, concave spherical surface body vibrations have instantly driven spheroid at it down and roll on the concave spherical surface on it, and this while of what, the fovea superior spherical surface body on its spheroid but keeps static.Thereby having protected the fovea superior spherical surface body is the safety and stability of building.

According to technical characterictic of the present invention, the request right protection is as follows:

1, all spheroids that utilizes are being kept away seismic structural (comprising a plurality of spheroids of deriving from this various ways at a plurality of upper and lower concave spherical surface body structure of a plurality of mutual make-ups) all in the rights protection scope on the concave spherical surface of two mutual make-ups.
2, by claim: the structure of keeping away earthquake and subtracting earthquake of various ways that (1) is derived from and close structure is about to spheroid as: the structure that the same concave spherical surface body of spheroid is an one, and to be embedded in the fovea superior spherical surface body be no matter its spheroid of one can freely rotate the form of structure that maybe can not rotate fixedly inlaying the place, all at the protection domain of this right.
