Description
(1) technical field
The invention belongs to Construction Anti-earthquake technical field, is related to a kind of dissipation using surrender deformation mechanism in mild steel face and is shaken
The antivibrator of energy.
(2) background technology
Seismic activity in recent years acutely, causes great infringement, has even resulted in serious personnel to engineering structure
A series of earthquakes such as injures and deaths, Wenchuan, cajaput, Lushan, Ludian show that China's town building is still faced with serious earthquake and threatens.With
The issue of new edition seismic rehionalization map, 7 degree of China and region area of setting up defences above increase to the 58% of national area, 82% province
Can city and 57% prefecture-level city be in 7 degree and the above is set up defences region.The antidetonation of how efficient and economic enhancing building structure
Ability is one of important topic of current protection against and mitigation of earthquake disasters engineering.The newest antidetonation that energy-dissipating and shock-absorbing technology exactly grows up for this
Technological means, dissipated by the way of " defeating a force with a tenderness " inputting seismic energy, is played the effect of " electric fuse ", is sacrificed oneself, is protected
Full agent structure component.On the one hand structural seismic capacity is greatly enhanced, on the other hand the fast changeable after shake.
Common energy-consuming shock absorber can be divided mainly into four big class：Viscous damper, metal damper, viscoelastic damper
And frcition damper.Metal mild steel damper is subject to the generally favor of people with the characteristic of its cheap, dependable performance.
Metal mild steel damper is using the plastic energy dissipation energy after metal material surrender.Metal mild steel damper hysteretic characteristic is steady
Fixed, low-Cycle Fatigue Characteristics are good, damping clear mechanism, and damping effect is notable, and not influenced by ambient temperature.Conventional metal is soft
Steel antivibrator adopts in-plane deformation dissipation energy, and based on detrusion, rigidity is big, and energy dissipation capacity is strong.But Wasted-energy steel plate easily occurs
Out-of-plane buckling, it is wayward；For the type of attachment of power consumption section steel plate is mostly welded, the low week that on the one hand have impact on antivibrator is tired
Labor performance, is on the other hand difficult to quick-replaceable after shake.Particularly, existing mild steel damper is just subject in the corner of Wasted-energy steel plate
The control of stress initially enters surrender, and accumulating plastic deformation is very big, and it is tired that test shows that this is that the type antivibrator occurs low week at first
The stress point of labor rupture failure.
(3) content of the invention
It is contemplated that overcoming the disadvantages mentioned above of conventional metals mild steel damper, it is proposed that a kind of new employing iso-stress
The assembled mild steel damper of line optimization.The device utilizes mild steel in-plane bending-detrusion mechanism dissipation seismic energy, by ground
Shake energy concentrates on mild-steel energy-consumption piece, and through section optimal so that during coming earthquake, the equivalent stress of the piece outer ledge that consumes energy
Maximum is reached simultaneously, stress isobar is formed, and improves the energy dissipation capacity of antivibrator, and the effectively peak value of reduction accumulating plastic deformation,
So as to improve low-cycle fatigue ability.Using full articulated constuction, even if there is residual force after shake in antivibrator, also can be convenient
It is removed and replaced for, so as to reach the ability that fast quick-recovery uses function.By the antivibrator used in building structure coupling beam,
Can use as wall antivibrator between levels.
The present invention is included using the assembled mild steel damper of stress isobar optimization：Mild-steel energy-consumption piece 1, anti-buckling clamping plate
2, L-type connecting cleat 3, anchor plate 4, polyfluortetraethylene plate 5, precompressed fastening bolt 6, the high-strength connecting bolt 7 of friction-type are spacing
Bolt 8, pre-buried anchor bar 9, flexible packing material 10, clamping plate pad 11, the antivibrator line style 12 of stress isobar optimization, screw thread
Hole 13.
Wherein anchor plate 4 is embedded in concrete connecting-beam securely with pre-buried anchor bar 9, and anchor plate 4 is provided with spiral shell
Pit 13 is connected with anchor plate 4 by L-type connecting cleat 3 to connect L-type connecting cleat 3, mild-steel energy-consumption piece 1, mild steel consumption
Can piece 1 and 3 junction of L-type connecting cleat open bolt hole, and connected by the high-strength connecting bolt of friction-type 7, multigroup mild-steel energy-consumption
When piece 1 is in parallel, clamping plate pad 11 should be set, L-type connecting cleat 3 opens bolt hole with 4 junction of coupling beam anchor plate, also by rubbing
The high-strength connecting bolt of wiping type 7 connects, and anti-buckling clamping plate 2 arranges bolt hole in the vacancy of 1 boundary curve of mild-steel energy-consumption piece, passes through
Mild-steel energy-consumption piece 1 is clamped and prevents out-of-plane buckling by precompressed fastening bolt 6, places poly- between anti-buckling clamping plate 2 and mild-steel energy-consumption piece 1
Tetrafluoroethene plate 5 reduces the frictional force that face pressure causes, and arranges caging bolt 8 to position anti-buckling clamping plate in the middle part of mild-steel energy-consumption piece 1
2, the antivibrator line style 12 of stress isobar optimization is shaped as in the middle part of mild-steel energy-consumption piece 1, its exterior wraps up one layer of flexible filling
Material 10 prevents corrosion.
The intensity of antivibrator is not to be exceeded the intensity of coupling beam concrete parts, and the stiffnes s equivalent of whole coupling beam is firm into antivibrator
Degree is connected with two section concrete coupling beam rigidity, and overall coupling beam rigidity is equivalent with former concrete connecting-beam.Under frequently occurred earthquake, mild steel
Power consumption piece is in elastic stage, and antivibrator provides the initial stiffness equivalent with original reinforced concrete coupling beamses.Under earthquake of setting up defences,
Antivibrator initially enters yield situation, and mild-steel energy-consumption piece starts dissipation seismic energy by shearing lag return mechanism earthquake energy
Amount, and protect concrete component to exempt from destruction.Under rarely occurred earthquake, there is the larger shearing changing of the relative positions in coupling beam, antivibrator into compared with
Big mecystasises, dissipate a large amount of seismic energies, so as to reduce integrally-built seismic response.
The present invention deforms larger position, such as coupling beam or stratified deformation under geological process in being applied to engineering structure.
When being applied between two-layer, connection buttress should be set, multiple antivibrator parallel operations, connection can be set on connection buttress
Pier should have enough rigidity and intensity, it is to avoid surrender earlier than antivibrator and destroy.
Structural damage under severe earthquake action is concentrated on antivibrator by the invention, so as to avoid other concrete components, such as
, there is destruction in wall limb, be finally reached lifting overall structure anti-seismic performance, control damage, ensure shake after can quickly repair, reduce Jing
The purpose of Ji loss.
Beneficial effects of the present invention：
The present invention is metallic article, surface through strict antiseptic and rustproof process, with good durability；The present invention
Simple structure, clearly, dependable performance is easy for installation for mechanics approach, is easy to the quick-replaceable after shaking；The present invention is when earthquake occurs
The energy that the earthquake that can dissipate is transmitted to building, reduces the seismic response of agent structure；Can be used for high level, super high rise structure to subtract
Shake, effect are obvious；The strength and stiffness flexible design of the present invention, can be arranged as required to the diverse location in engineering structure.
