Abstract
The utility model discloses a high-damping lamination rubber gasket comprising an upper connection steel board, a lower connection steel board and lamination rubber, wherein the lamination rubber is located between the upper connection steel board and the lower connection steel board, and is formed by alternatively overlapping the rubber with a lead core and a middle steel board; an inner hole is formed at the center position of the lamination rubber; an opening of the inner hole is located at the bottom of the lower connection steel board; a layer of buffering protection rubber is arranged on the wall of the inner hole; a limiting steel bar is inserted into the inner hole; and a gap is reserved between the limiting steel bar and the upper connection steel board, and is 8mm high. According to the high-damping lamination rubber gasket disclosed by the utility model, the limiting steel bar is inserted in the lamination rubber, and is stressed to be bent, so as to supply damping force. Therefore, the effect of protecting the high-damping lamination rubber gasket can be realized, and the high-damping lamination rubber gasket has higher actual application value.
Description
Technical field
The utility model relates to construction engineering technical field, particularly a kind of high damping laminated rubber bearing.
Background technology
Earthquake is the natural calamity of a kind of serious threat human survival and development, and its sudden and destructiveness can make an area become a slice ruins in moment.Thousands of times earthquakes will take place every year in the whole world, this wherein damaging shake doughtily also have tens times.In recent years, violent earthquake has many times taken place in the whole world, comprises Wenchuan devastating earthquake in China, Indonesia's violent earthquake, the cajaput earthquake of Chinese Qinghai, Haiti violent earthquake, Chilean violent earthquake and year Japanese violent earthquake etc., has caused very heavy life and property loss to the mankind.Earthquake have an emergentness, its duration is often also shorter, generally all in tens to tens seconds, but the destructive power that earthquake causes be other natural calamities can't compare.Because earthquake is sudden, and also do not search out effective earthquake prediction means so far, casualties and property loss that each violent earthquake causes all are surprising.Along with the progress of society, urbanization is fast-developing, in case destructive violent earthquake takes place, will cause very serious consequence.Human in the process of struggling with earthquake, develop gradually and a rational and effective antidetonation approach-engineering structures damping control.
The high damping laminated rubber bearing can use separately in shock isolation system and need not to establish in addition damper, makes shock isolation system become fairly simple.The major cycle of ground motion requires the horizontal rigidity of shock insulation layer very little in principle when avoiding macroseism; But along with shock insulation layer horizontal rigidity reduce with severe earthquake action under the increase of seismic wave low-frequency range energy, will cause the horizontal sidesway of shock insulation layer significantly to increase, and due to economic considerations, the diameter of rubber vibration isolation cushion again can not be too big.
The utility model content
For this reason, the utility model proposes a kind of high damping laminated rubber bearing, can eliminate fully because the restriction of prior art and one or more problems that defective causes.
The utility model additional advantage, purpose and characteristic, a part will be illustrated in the following description, and another part will be significantly for those of ordinary skill in the art by the investigation to following explanation or acquire from enforcement of the present utility model.Can realize and obtain the utility model purpose and advantage by the structure of in the manual of literal and claims and accompanying drawing, pointing out especially.
The utility model provides a kind of high damping laminated rubber bearing; it is characterized in that; described high damping laminated rubber bearing comprises: on connect steel plate; under connect steel plate and laminated rubber; described laminated rubber is at described connection steel plate and connect between the steel plate down; described laminated rubber alternately is formed by stacking by rubber and the middle steel plate of band lead for retractable pencil; centre position at described laminated rubber has endoporus; the opening of described endoporus is positioned at the described bottom that connects steel plate down; be provided with one deck buffer protection rubber at inner hole wall; spacing rod iron is inserted in the described endoporus; described spacing rod iron with on be connected and remain with the slit between the steel plate, the height in this slit is 8 millimeters.
Preferably, described spacing rod iron is mild steel bar, and the top of described mild steel bar is the spherical crown shape.
Preferably, have 24 lead for retractable pencils in the rubber of described band lead for retractable pencil.
Preferably, the diameter of described lead for retractable pencil is 70 millimeters.
The utility model has inserted the mild steel bar as spacing rod iron in laminated rubber; the top of described mild steel bar is the spherical crown shape; and with on be connected and remain with the slit between the steel plate; the purpose of doing like this is to make going up of shock insulation pad connect steel plate in order to prevent from producing vertical displacement behind the shock insulation pad pressurized might contact rod iron; rod iron can not be out of shape as scheduled so that can not bring into play effective position-limiting action; the stressed bending of described mild steel bar can provide damping force, thereby plays the effect of protection high damping laminated rubber bearing.
