Abstract
The invention relates to an anti-seismic device for a high-rise rotating mechanism. The high-rise rotating mechanism comprises a lower fixing component and a rotating body, the lower fixing component comprises a core column and a base, the lower end of the core column is fixed to the base, the upper end of the core column penetrates through the center of the rotating body, and the rotating body is sleeved on the core column. The anti-seismic device is characterized by comprising a yieldable rod, a damper and a seismic isolation layer, wherein the yieldable rod is arranged on the core column and connected with the rotating body, the damper is arranged between the core column and the rotating body, and the seismic isolation layer is arranged between the rotating body and the base. Compared with the prior art, the anti-seismic device is fine in anti-seismic performance and has a seismic resistance effect for a lower building.
Description
Technical field
The present invention relates to a kind of antishock device, especially relate to a kind of antishock device for high-rise rotating mechanism.
Background technology
Along with the development of urbanization process, a large amount of high-rise buildings stand erect in the city, and for people's view of ascending a height provides condition, now a lot of large-and-medium size cities all have and have rotation at the high-rise building top and go sightseeing layer to better meet this needs.The building of the top band rotating layer of building at present, the technology that usually adopts is: the upper convex portion with larger rigidity that high-rise (Super High) building top rotary building protrudes around its underpart main body fixed building is divided into axle and is rotated.
Real rotational structure, throw off completely its rotating part and bottom, and this is a difficult problem in structure design not only, and the structural seismic difficulty is very large, and is domestic and even rotation building is all seldom in the world.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of anti-seismic performance good for the defective that overcomes above-mentioned prior art existence, can strengthen simultaneously the antishock device that is used for high-rise rotating mechanism of substrustion anti-seismic performance.
Purpose of the present invention can be achieved through the following technical solutions: a kind of antishock device for high-rise rotating mechanism, described high-rise rotating mechanism comprises lower floor's fixation kit and rotating main body, described lower floor fixation kit comprises core column and base portion, base portion is fixed in described core column lower end, the rotating main body center is passed in the upper end, described rotating main body is sheathed on the core column, it is characterized in that, described antishock device comprises can surrender rod member, damper and Seismic Isolation of Isolation Layer, the described rod member of surrendering is located on the core column and with rotating main body and is connected, described damper is located between core column and the rotating main body, and described Seismic Isolation of Isolation Layer is located between rotating main body and the base portion.
Be provided with shock isolating pedestal in the described Seismic Isolation of Isolation Layer.
The described rod member of surrendering is by being located at buckle and the core column clamping on the core column.
The natural frequency of the frequency of described rotating main body and lower floor's fixation kit approaches.
Compared with prior art, the present invention has the following advantages:
1) horizontal rigidity of Seismic Isolation of Isolation Layer is very little, and the shear strain of top-out concentrates on this layer during earthquake, thereby reduces the suffered shearing of wheel, prevents integrally-built destruction.
2) can surrender rod member owing to being provided with, when running into general wind load and little shake, rotating main body and base portion are rigidly connected, and can not cause excessive relative storey displacement; When running into large shake, can surrender rod member and destroy voluntarily, so that Seismic Isolation of Isolation Layer plays a role.
3) between rotating main body and core column, be provided with damper, utilize the characteristics of discontinuous generation relative displacement between the energy-dissipating property of damper and rotating main body and the base portion, guarantee the performance of rotating main body energy-dissipating and shock-absorbing.
4) Seismic Isolation of Isolation Layer is located at high level, do not need the larger displacement headspace that specially occurs when earthquake for Seismic Isolation of Isolation Layer, also the construction measure corresponding with headspace needn't be set, and the overturning or slip resistance analysis moment of whole building structure and the ratio of overturning moment are increased, guarantee that overturning does not occur earthquake resistant structure when earthquake.
5) this programme is considered as tuned mass damper, TMD with the rotating main body at top, has not only solved the anti-seismic problem of rotating main body self, and the antidetonation of base portion is also had significant effect, has realized the antidetonation doulbe-sides' victory.

The specific embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Embodiment
Shown in Fig. 1～3, a kind of antishock device for high-rise rotating mechanism, high-rise rotating mechanism comprises rotating main body 6 and lower floor's fixation kit, this lower floor's fixation kit comprises core column 5 and base portion 7, base portion 7 is fixed in core column 5 lower ends, rotating main body 6 centers are passed in the upper end, and rotating main body 6 is sheathed on the core column 5, is rotated take core column 5 as axle.Seismic Isolation of Isolation Layer 3 is located between rotating main body 6 and the base portion 7, is provided with shock isolating pedestal 2 in the Seismic Isolation of Isolation Layer 3, and the shear strain of top-out concentrates on this layer during earthquake, thereby reduces the suffered shearing of rotating main body 6 bottom Force transmission partses, prevents integrally-built destruction.Because Seismic Isolation of Isolation Layer 3 is located at high level, do not need the larger displacement headspace that specially occurs when earthquake for Seismic Isolation of Isolation Layer, also the construction measure corresponding with headspace needn't be set, and the overturning or slip resistance analysis moment of whole building structure and the ratio of overturning moment are increased, guarantee that overturning does not occur earthquake resistant structure when earthquake.Can surrender rod member 4 and be connected on the core column 5 and with rotating main body 6 and be connected, when running into general wind load and little shake, rotating main body 6 is rigidly connected with base portion 7, can not cause excessive relative storey displacement; Can surrender the intensity of rod member 4 and determine according to earthquake magnitude, when earthquake magnitude reaches default earthquake magnitude, can surrender rod member 4 and destroy voluntarily, so that Seismic Isolation of Isolation Layer 3 plays a role.Damper 1 is located between rotating main body 6 and the core column 5, with not producing continuously the characteristics of relative displacement between the energy-dissipating property of damper 1 and rotating main body 6 and the base portion 7, guarantees the performance of rotating main body 6 energy-dissipating and shock-absorbings.
Apparatus of the present invention are applied to high-rise revolving restaurant, when design, considering quality and rigidity, regulate the frequency of revolving restaurant, the natural frequency of itself and lower floor's fixed building is approached, according to tuned mass damper, TMD (tuned mass damper) theory, when can make the revolving restaurant damping, the antidetonation of lower floor's fixed building has also been brought into play advantageous effect.
Apparatus of the present invention can also be applied to rotate sightseeing Room contour level rotation building except the revolving restaurant.
