Abstract
The invention relates to the field of damper designs, in particular to a viscoelastic damper with more reliable performance and a longer service life. The viscoelastic damper comprises an inner steel plate, a viscoelastic material, an outer guide rail, an inner guide rail and two outer steel plates, wherein the inner steel plate is mounted between the two outer steel plates; the inner and outer guide rails are mounted between the inner steel plate and the two outer steel plates; and the inner guide rail is occluded with the outer guide rail. The viscoelastic damper has the advantages that through arranging positioning devices such as the inner and outer guide rails which are used for positioning the viscoelastic material and simultaneously mounting the outer and inner guide rails in a mutually occluded manner, negative torsional force is provided, the inner and outer steel plates of the viscoelastic damper are prevented from relatively moving in a torsional mode, new working reliability of the viscoelastic damper is improved, and the service life of the viscoelastic damper is prolonged.
Description
Technical field
The present invention relates to the damper designs field, it is higher to relate in particular to a kind of functional reliability, the viscoelastic damper of longer service life.
Background technology
Present known viscoelastic damper is generally formed by three-ply plate and two layers of viscoelastic material alternate combinations, and is general, and a middle block plate is connected with beam in the structure by connector, and the outside two block plates are connected with the beam of another layer in the structure by connector.When structure is subjected to earthquake or wind load, relative displacement takes place, inside and outside steel plate generation relative motion between deck, drive viscoelastic material and back and forth be out of shape heating, loss of energy, thus also rapid attenuating structure reduced in earthquake or wind load action vibration, realize the purpose of oscillation damping and energy dissipating.
The viscoelastic damper of this structure can run into following problem in engineering is used: be subjected to the restriction of connector rigidity, to produce relatively between viscoelastic damper middle steel plate and the outer layer plate during damper action and reverse, cause the viscoelastic material layer distortion inhomogeneous, the bight distortion is big, can destroy in advance, further be diffused into whole viscoelastic layer, cause damper to lose efficacy, existing thus viscoelastic damper can not be by the motion mode work of designing requirement, damping force does not reach requirement, can not the vibration of effective attenuation structure under earthquake or wind load action, functional reliability is lower, has also shortened the life-span of damper simultaneously.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of functional reliability higher, the viscoelastic damper of longer service life.
In order to realize the foregoing invention purpose, technical scheme of the present invention is:
Comprise interior steel plate, viscoelastic material, outer guide, interior guide rail, two blocks of outer steel plates; Steel plate is installed between two blocks of outer steel plates in described, described in guide rail and outer guide be fixed on slit between interior steel plate and the two blocks of outer steel plates simultaneously, the mutual interlock of interior guide rail and outer guide is filled with viscoelastic material at the end face of outer guide.。
Optionally, also comprise pin, be used for be arranged on interior steel plate, outer steel plate, outer guide, interior guide rail on locating hole cooperate fixing.
Optionally, the bottom of steel plate or outer steel plate has extension in described.
Optionally, the slit in described outer guide, interior guide rail are weldingly fixed on simultaneously between steel plate and the two blocks of outer steel plates.
The present invention is by being provided with positioners such as inside and outside guide rail, be used to locate viscoelastic material, interlock installation mutually between outer guide and the interior guide rail simultaneously, detorsion power is provided, prevented the relative twist motion of the inside and outside steel plate of the present invention, improve the reliability of the new work of this practicality, and increased application life of the present invention.
The present invention can also offer locating hole respectively on interior steel plate, outer steel plate, outer guide, interior guide rail, utilize dowel fixes, has better increased antitorque commentaries on classics performance of the present invention, makes work of the present invention more reliable, longer service life.
