Abstract
A viscoelastic damper for anti-earthquake civil engineering is composed of intermediate steel plate, two side steel plates, damping layers and lead pins. Said damping layers are stuck on both sides of intermediate steel plate. The side steel plate is stuck on outer surface of damping layer. The lead pins pass through them via holes to form a whole body.
Description
The present invention is a kind of antidetonation and damping device that is applied to civil engineering.
Along with the increase of building height, how to guarantee the travelling comfort of structure when earthquake or wind carry bearing capacity under the effect, deformability and use; Under the violent earthquake effect, how to guarantee the safety of structure to greatest extent, do not cause lives and properties to suffer heavy losses; Along with the development of society, high, precision and frontier technical equipment such as computer, communication, electric power and medical treatment enter building, and these technical equipment can normally be moved and the destruction of reason building structure not when how to guarantee that earthquake takes place, and cause or increase the weight of secondary disaster.Addressing these problems is the comparison difficulty, and for common buildings, when being equivalent to the seismic interference of basic intensity, structure promptly may enter the elastoplasticity working state, produces bigger displacement.One comparatively reasonable approach adopt the structural seismic response control technique exactly, make building satisfy the requirement of above-mentioned function, livability and safety of structure simultaneously.This is current aspect structural seismic, comprises the new way that test the various countries of China, develop, use and progressively grow up.
Viscoelasticity vibration damping energy dissipating damper is as a kind of effective means of building structure energy-eliminating shock-absorbing, alleviates the reactions of engineering structure under earthquake and wind-force effect such as multi-rise building, bridge, tower mast on can be largely, guarantees its Security under shaking by force.The visco-elastic damping material that viscoelastic damper uses is a kind of high molecular polymer.Visco-elastic damping material is used in military affairs, space flight, aviation, automobile and the mechanical engineering the earliest, but they all belong to the high frequency damping technology.The vibration that building or bridge produce under wind, geological process is the multi-freedom degree low-frequency vibration, and its damping technology is a new research field.At present, countries such as the U.S., Japan and New Zealand maintain the leading position in this Research on New with in using.External development and what use in engineering all is viscoelastic dampers of no lead dot, it is less that such viscoelastic damper exists initial stiffness, the bigger shortcoming of creeping of the distortion one under the long term loading.
Purpose of the present invention just provides a kind of dynamic responses of engineering structure under wind and geological process such as multi-rise building, tall and slender structure, bridge structure, large-span structure that can be used for alleviating, and improves the antivibration reliability of engineering structure and reduces the viscoelastic damper of lead pin for engineering structure of engineering cost.
Viscoelastic damper of lead pin for engineering structure of the present invention is made up of middle steel plate, both sides steel plate, damping layer, lead dot, both sides at middle steel plate are bonded with damping layer respectively, the outside at damping layer is bonded with the both sides steel plate respectively, on middle steel plate, both sides steel plate and damping layer, be respectively equipped with the lead dot hole, lead dot is through in the lead dot hole, and middle steel plate, both sides steel plate, damping layer are held together.Damping layer can alternately be arranged the steel plate and the damping material layer that are provided with by polylith and form multi-layer structure.
The invention has the advantages that this damper can be used for alleviating the dynamic responses of engineering structure under wind and geological process such as multi-rise building, tall and slender structure, bridge structure, large-span structure, the Aseismic Reliability that improves engineering structure also reduces engineering cost, its concrete advantage have following some:
1. " viscoelastic damper of lead pin for engineering structure " invented has enough rigidity, and distortion and the stability of control structure under wind action can reduce the time deformation of structure under action of long-term load effectively effectively;
2. " viscoelastic damper of lead pin for engineering structure " invented can absorb vibrational energy effectively by the visco-elastic damping layer that is arranged between middle steel plate and both sides steel plate;
3. " viscoelastic damper of lead pin for engineering structure " invented can improve its rigidity and energy dissipation capacity effectively by passing across the lead dot of both sides steel plate, middle steel plate and visco-elastic damping layer;
4. " viscoelastic damper of lead pin for engineering structure " invented can be used for the inhibition of the structural vibration that horizontal vibration and vertical motion cause;
5. " viscoelastic damper of lead pin for engineering structure " invented can be used for the vibration damping of building structure, bridge structure and large-span structure or the like various engineering structure;
6. " viscoelastic damper of lead pin for engineering structure " simple structure of being invented, power transmission is clear and definite, mechanism is clear.
Fig. 1 is a general structure schematic representation of the present invention, and middle steel plate 1, attachment hole 11 are wherein arranged; Both sides steel plate 2, attachment hole 21; Damping layer 3, lead dot 4.
Fig. 2 is the damping layer that multilayer steel plates, damping are arranged alternately the multi-layer structure of composition layer by layer.Comprising viscoelastic material layer 31, steel plate 32.
Embodiment of the present invention are as follows:
Make middle steel plate 1 and both sides steel plate 2 at first respectively, and on steel plate, be processed with lead dot hole and attachment hole respectively, and then making damping laminate, between middle steel plate 1 and both sides steel plate 2, paste damping layer 3 then, damping layer material can adopt nitrile butadiene rubber, wherein damping layer 3 also can alternately be arranged the steel plate of setting and the damping material layer that the damping material layer is formed multi-layer structure by polylith, at last lead dot 4 is through in the lead dot hole, middle steel plate 1, both sides steel plate 2, viscoelastic material 3 are held together.Just can realize the present invention according to the above.
