Stirrup 3 connects to form framework of steel reinforcement by steel wire lashing, core part of the force of the framework of steel reinforcement as reinforced column component
With the effect of concrete shared power.
When coming earthquake, under small shake effect, frame structure itself forms an entirety, resists by its own rigidity
Geological process.At this point, structure is in elastic stage, can restore after small stratified deformation and shake only occurs, structure does not occur
Damage and destruction.
When the coming earthquake shaken in middle shake and in surmounting, frame column suspension column construction designed by the present invention begins participating in resistance
Geological process consumes energy, and earthquake reduces the effect of structure.Armored concrete concrete column 1, which starts to generate, to wave, and waves
Mechanism is as shown in attached drawing Fig. 2, and for frame structure, shaft, which waves, drives superstructure starting unboiled water under geological process to redress
It is multiple mobile.Under biggish geological process, three lines of defence of the invention --- elastic cushion 5, presstressed reinforcing steel 6 and spring 11 are sent out jointly
Raw effect, resists geological process, earthquake energy, the specific working principle is as follows:
Under the horizontal thrust of geological process, structure transmits the force to reinforced column after 2 stress of basis of underground
1, there is 1 side of concrete column elastomeric elastic cushion 5 compressive deformation occurs under the thrust that concrete column 1 transmits, and make
Concrete column 1 can wave, by structure wave in the way of come earthquake energy.
Presstressed reinforcing steel 6 is pulled back shaft 1 when concrete column 1 waves and offsets to one side and deform using prestressing force, limitation
1 rocking tendency of concrete column is excessive, and superstructure is caused to generate excessive deformation.Steel boots 7 and steel plate 13 play protection RC coagulation
1 column bottom of earth pillar and basis 2 contact the effect of surface concrete and the effect of anchoring prestress reinforcing bar.
By the column bottom Uplift Mechanism schematic diagram of Fig. 2 it can be seen that when concrete column 1 waves, at the rim of a cup on basis 2
The extruding of elastic cushion 5 is the most serious, and when horizontal earthquake action power is excessive, the cup of meeting and basis 2 after excessive wave occurs for concrete column 1
It collides at mouthful.Spring 11 is arranged at basic rim of a cup, using its biggish rigidity and preferable elastic property, at this
It is directly contacted with concrete column 1 to resist the horizontal force of the transmitting of column 1, is further delayed by way of 11 compressive deformation of spring
Punching is transmitted to the active force on basic 2 rim of a cup concrete, and concrete column 1 is avoided to occur under big shake or super large geological process
Waving rear concrete generation collision greatly causes concrete to be crushed.Because the rigidity of spring 11 is larger, in the effect of identical power
Under, the compression deformation of spring 11 is much smaller compared with elastic cushion 5, so the setting of spring 11 can reduce shaft 1 and occur at this
Wave the amplitude of deformation, the horizontal displacement that limitation upper part structure generates.Meanwhile spring 11 and elastic cushion 5 cooperate at this,
Pass through the compressive deformation earthquake energy of itself.The steel plate 8 of connecting spring beam-ends plays connecting spring and protection beam-ends herein
The effect of concrete.
After earthquake event resolves, acted in the elastic restoring force of the prestressing force of presstressed reinforcing steel 6, elastic cushion 5 and spring 11
Under, concrete column 1 " rebound " returns to script position, and presstressed reinforcing steel 6, elastic cushion 5 and spring 11, which do not occur to destroy, to be also returned to normally
State.When geological process is transmitted from other direction, the mechanical behavior of concrete column 1 is identical as above-mentioned mechanism, and only direction changes
Become.And so on, frame structure can under geological process by under the action of this triple defence line by formed swinging structure come
Earthquake energy realizes " big shake can repair " or " super large to achieve the purpose that " no collapsing with strong earthquake " at even " super no collapsing with strong earthquake "
Shake can repair " target.
It is mainly logical it is an object of the invention to design a kind of reinforced concrete frame column of achievable runback bit function
It crosses and Aseismic Design is carried out to the suspension column of concrete column 1 and applies certain construction measure, by keeping concrete column 1 real in earthquake
The mode of existing " waving " carrys out earthquake energy, and concrete column 1 can return to normal condition, while concrete from master reset after shake
The suspension column of column 1 does not occur to destroy or slight damage only occurs to be still able to continue to use after simply repairing.
Thinking of the invention is individually carried out pouring and to form two individual components to concrete column 1 and with underground foundation
Mode reduces the constraint between concrete column and basis, so as to mitigate the destruction of suspension column, then by applying in contact surface
Certain construction measure is added to achieve the effect that Self-resetting.Concrete measure is as follows:
Filling placement elasticity is big, intensity is high, wear-resisting property is good between the suspension column and basic contact surface in rim of a cup basis
Elastic cushion 5, elastic cushion 5 select rubber, as " the first heavy defence line " for resisting geological process earthquake energy.In geological process
Under, the good elastic property of elastic cushion 5 makes its stress generate compressive deformation, allows concrete column that " waving " occurs, and passes through left and right
It shakes to consume energy；After geological process disappears, the elastic restoring force of rubber, which gives, makes it under the certain propulsive thrust effect of concrete column
Return to normal position, at the same rubber also act as the effect of confined concrete models and prevent between concrete column and basis because compared with
Big collision and there is a phenomenon where crushing of concrete.
It places no-cohesive prestressed reinforcement 6 in concrete column 1 to connect with the basis 2 at 1 column bottom of concrete column, as can
Concrete column is set to realize " the second heavy defence line " of runback bit function.When geological process reaches to a certain degree, concrete column 1 is shaken
Swing degree becomes larger, since concrete column 1 and basis 2 do not consolidate, so concrete column 1 is in rocking process center pillar by a relatively large margin
Foot will appear " lifting ", i.e., suspension column side is detached from basis and no longer contacts with basis, and the effect of deformed bar 6 is made in earthquake
It is acted on by prestressed so that concrete column 1 returns to normal condition with after disappearance.The application of structural initial pre stress can also make to mix
Solidifying earth pillar 1 forms an entirety with basis 2, is equivalent to the effect of consolidation in normal state.In order to protect the column of concrete column 1
Steel boots 7 are arranged in suspension column bottom in concrete at foot plate surface and basic 2 contact surfaces, on the basis of be laid with steel plate 13.While in order to
The tensioning of presstressed reinforcing steel is facilitated to be arranged and implement, in capital, anchored end is arranged in steel plate for the stretching end setting of deformed bar
Under basis in.
It is excessive to generate the amplitude waved under special violent earthquake effect for concrete column in order to prevent, so that the top of frame
Excessive displacement deformation occurs for structure, and the biggish spring 11 of rigidity is arranged in basic rim of a cup and suspension column contact position in the present invention, to support
The amplitude that the excessive horizontal thrust that anti-concrete column is subject to when waving is waved to limitation and restriction shaft, so that top is tied
Structure is unlikely to generate biggish deformation, and the setting of spring forms " the third weight defence line " of concrete column self-recovering function design.Bullet
The setting of spring 11 can also prevent the suspension column in basic rim of a cup occur it is biggish wave after deformation with occur biggish to touch at the top of rim of a cup
It hits and extruding is crushed concrete.Being placed on the steel plate 8 among suspension column and spring can be at shaft and basic downthrust
It is that stress is concentrated in face that line, which concentrates stress check calculation, has further prevented the damage of concrete, has been placed on basis and the steel among spring
Plate can make the concrete of surface of base at this not because excessive impact force generates destruction.Equally, the restoring force of spring can make
Concrete column is in post earthquake recovery to script state.Spring only connect with basis and passes to the horizontal thrust being subject in the present invention
Basis, 11 other side steel plate of spring contacted with the suspension column of concrete column 1 but and be not connected to, with guarantee concrete column 1 shaft only
By being allowed to generate the horizontal earthquake thrust waved and be allowed to restore the elastic restoring force of the spring of normal condition and rubber, without
By any pulling force.
What the present invention designed can be realized the suspension column construction of the reinforced concrete frame column of runback bit function, can make to be arranged
Triple " defence lines " collective effect under geological process do not produced while structure consumes geological process by way of waving
Serious destruction does not occur for raw excessive deformation, suspension column concrete, the important component of structure does not generate destruction or only generates slight
Destruction, thus building structure do not collapse destroy and can continue to come into operation after simply repairing.
The above content is merely illustrative of the invention's technical idea, and this does not limit the scope of protection of the present invention, all to press
According to technical idea proposed by the present invention, any changes made on the basis of the technical scheme each falls within claims of the present invention
Protection scope within.
