Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
As shown in Figs. 1-3, a kind of high-rise outer wall decoration construction for being capable of self-balancing provided in this embodiment is hung with anti-wind shake
Basket, including hanging basket body 1, slide 2, sliding block 3 and damping spring 4, slide 2, sliding block 3 and damping spring 4 constitute one it is simple,
Economic vibrationproof system has prominent vibration-isolating effect；The bottom of the hanging basket body 1 sets parallel with 1 long side of hanging basket body
Slide 2, sliding block 3 can slide on slide 2,2 length of slide be preferably it is consistent with 1 length of hanging basket body, sliding block 3
Quality is needed according to resonance principle and local Climate Design；The both ends of the sliding block 3 are fixed on respectively by damping spring 4 hangs
The end of basket body 1, and damping spring 4 is parallel with slide 2, the rigidity of damping spring 4 is moderate, and sliding block 3 can be made to be applied calm
The center of slide 2 is maintained at during work condition；Damping spring 4 may be employed to be composed in parallel by a damper 5 and a spring 6；
The hanging basket body 1 is made of high-strength steel, has enough bearing capacities；The slide 2 is by the steel with enough bearing capacities
It is made；The sliding block 4 is made of the material of certain mass, such as cast iron, concrete block etc..When vibrationproof hanging basket vibration amplitude compared with
Hour, i.e., corresponding to the construction loads effect of windless condition when, sliding block 3 is maintained at the center of slide 3 under the action of damping spring 4
It is of reciprocating vibration nearby；When vibrationproof hanging basket amplitude is larger, that is, when corresponding to the construction loads effect for having wind state, set by special
The sliding block 3 of meter can resonate under wind action, so that the amplitude of sliding block 3 becomes very big, because damper 5 disappears
The energy of consumption and 3 amplitude of sliding block it is square directly proportional, so the sliding block 3 designed in this way can be with fluctuation dampers 5 greatly
The energy of dissipation vibrationproof hanging basket, so as to play the role of reducing vibrationproof hanging basket amplitude.In the present embodiment, the matter of sliding block 3 used
It measures as 18-22kg, increases in unobvious in the case that hanging basket bears a heavy burden, can significantly prevent hanging basket shaking in the construction process
It is dynamic, ensure the safety of construction personnel.
As shown in figure 4, the shape of sliding block 3 is cylinder, both ends are equipped with circular protrusion 10；There are two horizontal for vibrationproof hanging basket tool
Section is the slide 2 of C-shaped；Circular protrusion 10 is embedded in the C-channel of slide 2, and sliding block 3 can pass through the annular shape protrusion at both ends
10 slide on slide 2.
As shown in figure 5, damping spring 4 is composed in parallel by a damper 5 and a spring 6,4 one end of damping spring and cunning
Block 3 connects, and the end that the other end surveys hanging basket body 1 with place is connected；The enclosed hydraulic damping of velocity profile can be used in damper 5
Device；The periphery of the damping spring 4 can wrap up one layer of nylon cloth 9.
As shown in fig. 6, when vibrationproof hanging basket deviates equilbrium position, sliding block 3 is under gravity to vibrating phase
Anti- direction is slided, and damper 5 is made to do negative work, is played the role of the entire vibrationproof hanging basket energy that dissipates, is subtracted so as to play
The effect of few hanging basket amplitude.
The vibration attenuation mechanism of vibrationproof hanging basket of the present invention is as follows：
Basic principle is that in vibration, band fluctuation dampers consume energy using sliding block, so as to reduce the amplitude of hanging basket, in design,
The sliding block of consideration transference damping spring connection generates resonance, knows the energy of damper dissipation with shaking according to the acting formula of damper
Width it is square directly proportional, in order to which sliding block is made to generate maximum amplitude, optimize spring, damper, the selection of sliding block quality.
The spring added can enable sliding block be maintained at the center of hanging basket when entire hanging basket is static, can so make
Hanging basket is obtained when not rocking, center of gravity is remained on central axes so that hanging basket will not generate deflection.A spring is added in simultaneously
Afterwards, can be resonated by special design sliding block, the energy that increase damper dissipates, so as to play prominent vibration damping
Effect, concrete principle are as described below.
Basic principle：
Sliding block between upper lower skateboard does the forced vibration of damping, and since power is gained knowledge, obtaining its equation of motion has：
Order
Wherein ccFor critical damping, ζ is damping ratio, and c damps for damper, and x is the slider displacement letter that t changes at any time
Number, Be x to the first derivative and second dervative of time t, m is the quality of sliding block, and ω is the circular frequency of extraneous exciting force,
ωdFor self-vibration circular frequency, k is spring rate, F0For the amplitude of extraneous exciting force, t is the time.
So as to which equation is deformed into：
This is a nonhomogeneous Second Order with Constant Coefficients differential equation, and theoretical according to the differential equation, obtaining general solution has：
B, A are the constants related with primary condition, γ=ω/ωd
Because being forced vibration, when the time is longer, the vibration equation of sliding block deteriorates to following formula：
Damper work done is in the process：
In formulaAmplitude during forced vibration is done for sliding block, F is damping force, because adopting
With velocity profile damper, so
That is sliding block is in vibration, damping force work done and the amplitude of sliding block it is square directly proportional, in order to make
Vibration absorber has prominent effectiveness in vibration suppression, it should so that enough big of the amplitude of slider oscillation, i.e., sliding block is sent out as far as possible
Raw resonance.So damper work done is maximum, and the external world's (wind) that can dissipate to greatest extent is applied to the energy of hanging basket, that is, reduces
The amplitude of hanging basket.
By the derivation of front, the amplitude of sliding block to be caused to reach maximum, must be had：
It is maximized
Wherein γ=ω/ωd=, ζ=c/ (2m ω),
ω is related with the frequency that wind shake is moved in formula, and c is related with damper, and m is the quality of sliding block, ωdWith the rigidity of spring
It is related.
Example
In order to enable sliding block has maximum amplitude, ω, c must be there are one relational expressions between m, k.According to the operating mode often met,
The vibration frequency of wind load takes 8Hz, and c=2500N/mm, k=500N/mm are taken according to the rigidity of common damper and spring.For
Acquire the best in quality of sliding block, ω, c, relational expression between m, k is as follows：
HaveIt is minimized
It substitutes into solve and can obtain m=15.6kg, it is contemplated that slide friction that may be present if sliding block is too light, is not allowed
It easily slides, therefore under the operating mode, m=18kg~22kg can be taken.Sliding block is under the action of natural wind at this time, can generate compared with
Big vibration, so as to play good vibration isolating effect.
According to different regions, different natural wind frequencies can be taken, according to existing technique manufacturing situation, selection is suitable
Damper and spring, so as to acquire the optimum quality in different operating mode sliding blocks.
