Technical field
The utility model relates to a kind of new builing structure composite shock-absorbing (shaking) device---the anti-buckling support of tuning quality type (TMD-BRB), is a novel technique of civil engineering structure energy-dissipating and shock-absorbing (shaking) technical field.
Background technology
Anti-buckling support (BRB) is with its outstanding mechanical property, makes the features such as simple and maintenance cost is low, in recent years by a large amount of reinforcings for newly-built structure and existing structure.But traditional B RB has the restriction of threshold yield force, how to play a role more than middle shake, and shakes under condition in little shake and wind, compares the advantage of there is no with common support, cost is but higher than the latter.Tuned mass damper (TMD) is to apply one of wider control technology during current Wind Induced Vibration of Tall Buildings is controlled, but centralized TMD needs larger bracing or strutting arrangement and damping facility, and general industry and civilian construction are difficult to lay, and in function, tuning range is narrower, though checking shakes good, damping is not good enough; Though distributing TMD has made up the narrow problem of tuning range, its space hold is large, and financial cost is high.
The frequency-modulation mass anti-flection support (TMD-BRB) that Chinese patent (ZL200910077003.4) proposes, is incorporated into BRB cleverly by TMD function upper, has realized the combination of two kinds of dampers.It is characterized in that: utilize constraint sleeve as tuning quality, steel core is as vibrating the track.Between sleeve and steel core, remove limiting card in the past, by spring, realize connection.On constraint sleeve and steel core contact surface, add painting lubriation material, make sleeve become TMD oscillator and possess vibration condition.This On A Retrofitted Damper is taken into account damping (shaking) feature and the function of TMD and two kinds of dampers of BRB in theory simultaneously: wind shakes, under little shake condition, and oscillator can produce the effect of vibration that reverse inertia force weakens agent structure; And in middle shake, greatly under shake and super large shake condition, member can be brought into play again its BRB function, the plastic strain by steel core realizes power consumption.
But there are aborning several technological difficulties in TMD-BRB: the bad control of the friction of contact surface between (1) oscillator and steel core, even if adopt sliding agent, it is also more difficult that index of correlation will reach designing requirement; (2) sliding structure is to member initial bending, and the smoothness of slide plane etc. require harsh, and need fine finishining, and common building member processing factory is difficult to bear; (3) slideway is very easily blocked by solid particle polluters such as sandstone in processing and use procedure, and relevant maintenance is also pretty troublesome; (4) durability of sliding agent and sealing problem are difficult for solving.
Except above-mentioned technological difficulties, because sliding component is comparatively accurate, a series of expenses such as its transportation, installation, maintenance etc. all can correspondingly improve.Aspect marketing, there is predicament in the new technology that makes with high costs.For new technology can really be entered into the market, service society, the utmost point needs a set of cheap, simple and can meet the supporting working skill that relevant design requires.
Utility model content

Preferably, described roller form comprises infundibulate solid, cylindrical geometric body.
Preferably, described constraint sleeve inner can packing material.
Preferably, described packing material is concrete and all granular materials.
Preferably, described constraint sleeve two ends can be extended, and resilient element can stretch into confining part.
Preferably, described resilient element is that spiral draws high spring and Compress Spring.
Compared with prior art, the tumbling-type TMD-BRB the utility model proposes has obvious technology and economic advantages:
1, the utility model utilizes special roller that sliding friction is become to rolling friction, and friction factor is compared in the past and dwindled nearly 40 times, and the TMD performance of member is increased dramatically; And test according to static(al) tension and compression, the correlated performance of BRB also can meet the requirement of rules < < JG/T209-2012 building energy dissipation damper > >, illustrates that relative configurations has realized " the taking into account " to composite shock-absorbing function.
2, " combined type constraint sleeve " and " welding afterwards assembling method " of the utility model proposes, can guarantee that described rolling TMD-BRB member is on material usage, physical dimension and mode of appearance, compare no significant difference with former sliding component, but difficulty of processing and cost of manufacture reduce a lot, in general building unit processing factory, just can complete.
3, the engineering method that the utility model provides, avoided the harsh requirement to member steel core initial bending degree and the moving planar light slippery of oscillator sliding (rolling), as long as can reach the relevant regulations of common building standard (as < < GB50205-2001 code for acceptance of construction quality of steel structures > >), just can not affect the normal work of member, thereby more be conducive to integrate with mutually with existing building market.
4, the utility model avoided to sliding agent use, therefore need not consider the problem of any durability and sealing, in transportation, installation and use procedure, without adopting what special maintenance service, environmental suitability is strong.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Fig. 1 to Fig. 2 d, the present embodiment one is a kind of four pipe constraint cross core tumbling-type TMD-BRB.Its constraint sleeve, by four square band roller concrete filled steel pipes 5, combines around three grades of variable cross-section cross steel cores 2 of centre, and it is connected with spring 3a and 3b respectively with steel core two ends, jointly forms rolling TMD oscillator.
First, end boots seat 1 is welded on cross steel 2 and forms steel core.Boots seat 1 is spring 3a, 3b and the bearing that is connected of steel core, should possess certain out of plane stiffness.Cross steel 2 is three grades of variable cross-section cross steel cores: interlude be BRB active section be also TMD oscillator track; The second level is BRB changeover portion, and partial-length serves as TMD oscillator track; The third level is the linkage section of member and agent structure, is also to prevent that oscillator from moving past large limiting card at vibration processes meta simultaneously.For avoiding occurring end unstability, the thickness of the second level and third level steel core steel plate should be higher than active section.
By design size and number requirement, make (or purchasing) as shown in Fig. 3 a to 3c roller member several, and make (or purchasing) four square hollow steel pipes.As Fig. 4, select a steel pipe, after definite rolling contact surface, in steel tube surface, shown in operation I, slot, by fixed idler whell member 6 shown in operation II.For keeping the sealing of constraint sleeve 5, unsuitable with bolts herein.It is too many that in making, roller member 6 should not exceed constraint sleeve 5 table planes, should be controlled within the scope of 2-5mm.After roller member 6 has arranged, should first test in the plane and can normally roll, without difference one side of seal sleeve 5, concreting, vibrate and fill closely knit after, sealing another side, completes first " pipe car " and makes.Its excess-three of following the prescribed rules " pipe car ".
By shown in Fig. 5, make junction plate.For preventing that whole unstability from appearring in steel core, in the middle of junction plate, should weld a constraint floor is set.For there will not be whole unstability member (as member more in short-term), floor also can throw the reins to.
Press shown in Fig. 6 each " pipe car " is temporary fixed around steel core 2, cover junction plate 7.Be welded to connect plate 7 and sleeve 5, form TMD rolling oscillator, be also the constraint sleeve of BRB simultaneously.For improving the anti-buckling performance of confining part, junction plate 7 both sides should adopt full weld.After oscillator has been assembled, the experiment of gliding, to investigate the friction factor between TMD oscillator and track, if meet design requirement, adds shock mount at oscillator two ends, completes structure manufacture; If do not meet, cut junction plate, after suitably adjusting, re-start assembling, till reaching designing requirement.
For some larger members of camber of spring, may cause the long situation of steel core naked section, now can construct by shown in Fig. 7, sleeve 5 and junction plate 7 are stretched out to a part, but baffle plate 4 still maintains original position, then spring 3 (3a and 3b) is stretched in cylinder.So just can reduce steel core naked section length and make it local buckling can not occur herein, also not affect the flexible of spring simultaneously.
As Fig. 8, after member 13 is made, can be by the installation that achieves a butt joint of operation IV and agent structure.Because member is oblique placement, oscillator can be because there is initial a downslide in deadweight.So bottom spring 3a must possess pressurized resilience, and top spring 3b must possess tension resilience.If the correlated performance of spring can reach designing requirement, the situation that also allows to only have spring 3a or only have spring 3b to exist.
