Abstract
A kind of inner steel cylinder of chimney TMD damping device disclosed in the utility model, comprise steel corbel and damper, described steel corbel is located on the steel inner cylinder of chimney, and the bottom of steel corbel arranges damper, damper bottom is supported by platform girder steel, between platform girder steel and steel inner cylinder, arrange spring.The utility model improves the anti-seismic performance of suspension sleeve chimney under wind-induced vibration and geological process, adopt TMD quality coordination damping control system, using suspension steel inner cylinder as inertial mass, and be equipped with spring and be connected with concrete urceolus with damper, application resonance principle certain some vibration shape to structure are controlled.This cushion technique need not adopt traditional strengthening measure to main structure, simultaneously simple structure, implement convenient and damping effect is obvious, greatly can reduce the distortion of chimney under wind load and geological process.The utility model, under the prerequisite meeting the every normal function of chimney, has simple structure, required low cost, the obvious feature of damping effect.
Description
Technical field
The utility model relates to a kind of chimney internal cylinder damping device, is specifically related to a kind of inner steel cylinder of chimney TMD(tuned mass damper) damping device.
Background technology
Along with the development of civil engineering industry, structural design theory and numerical computation method constantly perfect, complicated, tall and slender structure is constantly built to and comes into operation, and the suspension sleeve chimney particularly in steam power station is constantly used as a kind of emerging form of structure.The Static Calculation problem of overhung construction can by strengthen structural meterials intensity, the methods such as the rigidity of structure are resolved, but the dynamic response of suspension sleeve chimney under wind load and seismic loading is comparatively complicated, how to improve the anti-seismic performance of suspension sleeve chimney under wind-induced vibration and geological process significant.
At present for suspension sleeve chimney, its steel concrete and the connection of steel inner cylinder adopt that platform girder steel directly welds with steel inner cylinder usually, platform girder steel and urceolus carry out the mode that is connected, due to the flex effect that temperature difference effect produces, this kind of mode easily produces larger thermal stresses at platform girder steel and steel inner cylinder junction.Patent CN201320820502.X discloses " a kind of chimney internal cylinder shock mount ", it mainly comprises the steel corbel be arranged on inner steel cylinder of chimney, steel corbel bottom arranges rubber cushion assembly, rubber cushion assembly bottom is supported by platform girder steel, this shock mount with damper can wind shake and earthquake time, when horizontal direction generation moderate finite deformation, compare rigidity (vertical direction) and stably bear the weight of steel inner cylinder thus the wind resistance of raising steel inner cylinder, antidetonation displacement capabilities, there is good compatible deformation ability, but this shock mount effectively cannot control the natural frequency of steel inner cylinder, the perturbed force of urceolus can not be offset preferably.
Summary of the invention
The purpose of this utility model is overcome the deficiencies in the prior art and provide a kind of inner steel cylinder of chimney TMD damping device.
The purpose of this utility model realizes with following technical proposals:
A kind of inner steel cylinder of chimney TMD damping device, comprise steel corbel and damper, described steel corbel is located on the steel inner cylinder of chimney, and the bottom of steel corbel arranges damper, damper bottom is supported by platform girder steel, between platform girder steel and steel inner cylinder, arrange spring.
Steel inner cylinder is connected with platform support steel beam by bolt with damper by described steel corbel.
Described steel corbel is located on steel inner cylinder by channel-section steel reinforcing prop, stiffening ring.
Described steel corbel and platform support steel beam are provided with ribs.
The inner steel cylinder of chimney TMD damping device that the utility model provides improves the anti-seismic performance of suspension sleeve chimney under wind-induced vibration and geological process, adopt TMD quality coordination damping control system, using suspension steel inner cylinder as inertial mass, and be equipped with spring and be connected with concrete urceolus with damper, application resonance principle certain some vibration shape to structure are controlled.When concrete urceolus bears dynamic action and vibrates, steel inner cylinder also produces relative inertness motion, the natural frequency of the horizontal rigidity adjustment steel inner cylinder of steel inner cylinder is changed by spring, when the natural frequency of steel inner cylinder and the frequency of urceolus reach certain relation, steel inner cylinder will apply active force in the other direction by spring and damper to urceolus, offset the perturbed force of urceolus, and concentrate energy dissipating by damper, make the dynamic respons exhaustion of urceolus.This cushion technique need not adopt traditional strengthening measure to main structure, simultaneously simple structure, implement convenient and damping effect is obvious, greatly can reduce the distortion of chimney under wind load and geological process.
The utility model, under the prerequisite meeting the every normal function of chimney, has simple structure, required low cost, the obvious feature of damping effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
A kind of inner steel cylinder of chimney TMD damping device, as shown in Figure 1, comprise steel corbel 5 and damper 2, described steel corbel 5 is located on the steel inner cylinder 4 of chimney, the bottom of steel corbel 5 arranges damper 2, damper 2 bottom is supported by platform girder steel 1, arranges spring 3 between platform girder steel 1 and steel inner cylinder 4.Steel inner cylinder 4 is connected with platform support steel beam 1 by bolt 6 with damper 2 by steel corbel 5, and steel corbel 5 is firmly located on steel inner cylinder 4 by channel-section steel reinforcing prop 7, stiffening ring 8, and steel corbel 5 and platform support steel beam 1 are provided with ribs 9.
In patent CN201320820502.X disclosed " a kind of chimney internal cylinder shock mount ", the major function of rubber cushion assembly is power consumption, does not establish spring, effectively cannot control the natural frequency of steel inner cylinder.The utility model compared with prior art, specially designed spring, with damper, suspension steel inner cylinder as matter block, jointly constitute TMD quality coordination damping control system, application resonance principle certain some vibration shape to structure are controlled.When concrete urceolus bears dynamic action and vibrates, steel inner cylinder also produces relative inertness motion, the natural frequency of the horizontal rigidity adjustment steel inner cylinder of steel inner cylinder is changed by spring, when the natural frequency of steel inner cylinder and the frequency of urceolus reach certain relation, steel inner cylinder will apply active force in the other direction by spring and damper to urceolus, offset the perturbed force of urceolus, and concentrate energy dissipating by damper, make the dynamic respons exhaustion of urceolus.This cushion technique need not adopt traditional strengthening measure to main structure, simultaneously simple structure, implement convenient and damping effect is obvious, greatly can reduce the distortion of chimney under wind load and geological process.
