Abstract
The present invention relates to a universal damper for high-rise buildings, which is composed of an upper sliding plate, a lower sliding plate, an upper universal ball, a lower universal ball, an upper universal ball seat, a lower ball seat, a spacing pull rod, a butterfly-shaped spring, etc. The universal damper is designed according to a principle that the upper sliding plate and the lower sliding plate generate slide under the actions of anti-tilting traction force and spacing of the upper universal ball, the lower universal ball and the spacing pull rod. When used, the universal damper is laid down on the base of a building, the lower base column of the universal damper and the base are in site cast into one body. A shearing force column at the upper end of the universal damper is connected with an interlaminar shearing force column of the building, a shearing force bean is installed on a sliding plate of the universal damper, and then is cast into one body by concrete. Tests in the use of construction show that the universal damper can earthquake energy by more than 7/8.
Description
What the present invention relates to is a kind of damping device, particularly a kind ofly is suitable between building foundation and the building body damping device that the prevention earthquake is used
Building constructions is more and more at present, and particularly tall building is also more and more, and the antidetonation that solves tall building is present very crucial problem.The shock-resistant arrangement of external design is also varied, steel ball dish isolator as the U.S., the rubber pad isolator of Japan etc., the advantage of these two big class isolators can weaken the shear wave amplitude of vibration in the earthquake, prolong the cycle of shake certainly of building, make it not shake altogether, thereby reduce the input of seismic energy building with the predominant period of earthquake.But the deficiency of this two classes isolator be the steel ball dish isolator of the U.S. when weakening shear wave, building height degree is risen, the building body pitches during the shear wave to-and-fro motion, this effect has weakened the weakening ability of steel ball dish isolator to shear wave.The rubber pad isolator one of Japan is that the amplitude of weakening earthquake shearing wave amplitude of vibration is less, the 2nd, and it is very inconvenient that the aging back of rubber pad is changed.Chinese patent 95227035.8 is used for the isolator of building foundation and building body, though overcome above-mentioned deficiency, structure is complicated.Chinese patent 96243536.8 slide block type vibration dampers, it is not very good to be used for the skyscraper effect.The present invention has designed a kind of universal damper that can be used for various buildings on the basis of preceding two patents.
The object of the invention is, a kind of amount of deflection that increases between connected piece is provided, and with vibration in improve a kind of damping device of its characteristic that automatically resets.This vibration damper is to adopt to slide up and down plate, universal spheroid, compositions such as universal ball seat, limit pull rod, butterfly spring up and down up and down, adopts to slide up and down plate produces slip under the antidumping pulling force of universal spheroid up and down and limit pull rod and spacing and effect in the buffering of butterfly spring principle design.This universal damper is simple in structure, and is easy to use, and it is good to be used for the building damping effect.
The universal damper of the present invention design, it by slide up and down plate, up and down universal spheroid, universal ball seat, limit pull rod, butterfly spring etc. are formed up and down, going up universal spheroid (15) is linking body structure with limit pull rod (5); Slide up and down plate (6), (7) at the middle part of limit pull rod (5), its lower slider plate (7) adopts bolt with lower seal tube (9); Universal spheroid (13) is enclosed within the below of limit pull rod (5) down, and then being inserted in guide sleeve (12), butterfly spring (11) is inserted in the periphery of guide sleeve (12), is inserted in spring pressure ring (10) again, its spring pressure ring (10) is withheld on butterfly spring, screws that nut is fixing to get final product; Go up universal spheroid (15) and be bumped in the universal ball seat (3), go up universal ball seat (3) and be fixed on the upper bush (4), upper bush (4) is welded on the upper sliding plate (6), is fixed with safety cover (2) on the top of last universal spheroid (15); Universal spheroid (13) is bumped into down in the universal ball seat (14) down, and following universal ball seat (14) is fixed on the lower sleeve (8), and lower sleeve (8) is welded as a whole with lower slider plate (7); Be welded with square sleeve (16) on the plate face of upper sliding plate (6), square sleeve (16) is fixing with shear column (1) welding, has the hole simultaneously on the plate face and is used for installing shear beam; The bottom of lower seal tube (9) is welded with foundation columns.

Further describe and provide embodiment below in conjunction with accompanying drawing
The universal damper of the present invention design, it by slide up and down plate, up and down universal spheroid, universal ball seat, limit pull rod, butterfly spring etc. are formed up and down, going up universal spheroid (15) is linking body structure with limit pull rod (5); Slide up and down plate (6), (7) at the middle part of limit pull rod (5), its lower slider plate (7) adopts bolt with lower seal tube (9); Universal spheroid (13) is enclosed within the below of limit pull rod (5) down, and then being inserted in guide sleeve (12), butterfly spring (11) is inserted in the periphery of guide sleeve (12), is inserted in spring pressure ring (10) again, its spring pressure ring (10) is withheld on butterfly spring, screws that nut is fixing to get final product; Go up universal spheroid (15) and be bumped in the universal ball seat (3), go up universal ball seat (3) and be fixed on the upper bush (4), upper bush (4) is welded on the upper sliding plate (6), is fixed with safety cover (2) on the top of last universal spheroid (15); Universal spheroid (13) is bumped into down in the universal ball seat (14) down, and following universal ball seat (14) is fixed on the lower sleeve (8), and lower sleeve (8) is welded as a whole with lower slider plate (7); Be welded with square sleeve (16) on the plate face of upper sliding plate (6), square sleeve (16) is fixing with shear column (1) welding, has the hole simultaneously on the plate face and is used for installing shear beam; The bottom of lower seal tube (9) is welded with foundation columns.In use, universal damper is positioned between building foundation and the building body, and the base foundation post of vibration damper becomes whole with the basis is cast-in-place, and the shear column on the vibration damper is connected with building interlaminar shear post, the vibration damper upper sliding plate is installed shear beam, builds up whole getting final product with concrete casting then.This universal damper can weaken more than 7/8 seismic energy through testing in building is used.
