Abstract
The invention discloses a damping structural body which belongs to the field of building construction. The damping structural body comprises a rubber body and steel plates arranged in the rubber body. The damping structural body is characterized in that a viscoelastic damping layer is arranged in the rubber body. The damping structural body has the advantages of stable damping effect, capabilities of isolating horizontal vibration components in different directions and weakening the vertical vibration component of the structural body, low price, easiness in manufacturing, different shapes such as a square shape, a cylindrical shape and the like according to different operating places and operating requirements and suitability for construction of high buildings and large mansions, bridges and the like as well as the shockproof field of mechanical equipment.
Description
Technical field
The invention belongs to buildings in general structure field, relate in particular to a kind of against shock device.
Background technology
In China's town and country construction, high buildings and large mansions are in a compact mass.Along with the continuous increase that infrastructure drops into, it is like a raging fire that the construction of bridge, highway is also carried out.Follow increasing and the continuous increase of height of these building quantity, the comfortableness when how to guarantee the supporting capacity of structure under the effect of earthquake or wind-force, deformability and use has been put in face of the people.Along with the development of society, advanced equipments of high grade and precision such as communication, electric power, computer have also entered in the high buildings and large mansions, thereby in construction during building, should consider to guarantee when earthquake takes place that these technical equipment can normally move.For buildings in general, when being subjected to seismic interference, structural element promptly may enter the elastoplasticity duty, produces bigger displacement.Therefore, for guaranteeing the safety of building, should seek a good approach that solves constructure shakeproof.
Traditional structure is shockproof to be to come shockproof by the performance of structure itself.This structural system of having strengthened had both increased construction costs, and shockproof effect is also undesirable.The base isolation technology is a kind of reasonable, the effective earthquake resistant engineering method that develops rapidly in recent years.By being set, the shock insulation layer that one deck has enough reliabilities controls the transmission of ground motion to superstructure between building and basis.Checking factually, the earthquake response of shock-insulating building are about 1/7 of shock insulation not.At present, researched and developed multiple earthquake isolating equipment both at home and abroad, as frictional slip earthquake isolating equipment, steel ball earthquake isolating equipment etc.These devices or unstable properties, or cost is higher.
Along with the research and development of anti-seismic technology, it is shockproof that people have adopted a kind of lead core rubber support again.Lead core rubber support is that round lead for retractable pencil is set in common laminated rubber bearing, can significantly improve the damping characteristic of bearing, by changing the content of lead for retractable pencil area in the bearing, the damping ratio that can obtain expecting, prolong the cycle of building, reduce the effect of earthquake building.Reach the effect of shock-damping energy-dissipating by the hysteretic characteristic of lead core rubber support.Absorbing structure in the bearing is overlapped with natural rubber by steel sheet and makes, and is generally used for the weight of support of buildings, adds steel plate in the bearing and plays firm ballast effect, and laterally soft, proportion is suitable.Lead for retractable pencil and lead plug have been added at the center of absorbing structure.The function of lead plug mainly is that the kinetic energy of earthquake is transformed into heat energy, passes to building to stop vibrations.Absorbing structure can flexibly be out of shape in the horizontal direction during earthquake, directly passes to building with the power that stops earthquake, and in other words, absorbing structure plays a part the buffering seismic forces, when giving seismic forces to absorbing structure, is difficult to stop its slow motion in case distortion occurs.Although the damping of lead core rubber support is more satisfactory, its expensive price has also hindered its large-scale promotion application.And, because the damping of lead rubber bearing provides by the plastic strain and the Frictional Slipping of lead, its later stage damping stable wayward.
Summary of the invention
Problem for the shock-damping structure body that solves prior art exists the invention provides a kind of shock-damping structure body, and this structure is applicable to various vibration environments, and damping is stable and cheap.
The technical scheme that its technical problem that solves type of the present invention adopts is: design a kind of shock-damping structure body, comprise rubber bodies and be positioned at rubber bodies being the steel plate of arranging setting, it is characterized in that being provided with in the rubber bodies visco-elastic damping layer.
The present invention can vertically offer the hole in rubber bodies, place the metal cluster in the hole, embeds visco-elastic damping material between the metal bar; Also the hole can be offered vertically on rubber bodies and steel plate, the visco-elastic damping material of packing in the hole; The visco-elastic damping material layer can also be set between steel plate.
Damping material of the present invention can adopt solid-state viscoelastic material; Also can adopt viscous pill attitude damping agent.
The beneficial effect that the present invention had is:
(1) damping is stable, can not only isolate the horizontal vibrating component of different directions, can also weaken the vertical vibrations component of structure.
(2) cheap, make simple.
(3) the present invention can be according to different fields of employment and instructions for use, makes structures such as multi-form square, cylindricality, can be used for building high buildings and large mansions, bridge etc., also can be used for the shockproof field of plant equipment.
