The technology of the present invention includes following features:
1) surrender the realization of abduction mechanism.The described replaceable power consumption for being applied to the connection of assembly concrete frame beam column Coupling assembly is arranged on the upside and/or downside of assembly concrete frame structure beam-ends, power consumption core steel plate and anchoring in post Axial tension is born by being reliably connected one continuous force transferring part of composition under Moment between anchor block in block and beam Or the effect of pressure.In the present invention, the linkage section sectional area of power consumption core steel plate is more than power consumption section sectional area, and passes through difference Change performance design, it is ensured that when the core steel plate that consumes energy bears axial tension or axial compressive force, anchoring in anchor block, beam in post Block anchoring bearing capacity respectively in post concrete and in beam-ends concrete and its it is reliably connected between power consumption core steel plate Elastic carrier power be all higher than consuming energy core steel plate the surrender tension or in compression of power consumption section simultaneously Jing after tension and compression cyclic hardening repeatedly most Large bearing capacity;The post of power consumption core steel plate is equal to the elastic carrier power that linkage section bears axial tension and pressure to linkage section and beam More than the power consumption section of power consumption core steel plate surrender tension or in compression maximum load capacity simultaneously Jing after tension and compression cyclic hardening repeatedly;Power consumption The power consumption section of core steel plate is tension or in compression to surrender and Jing after tension and compression cyclic hardening repeatedly, structure under its corresponding bearing capacity Beam, post body do not produce damage or damage very little, and significant plastic deformation does not occur.It is former in such differential Performance Design Under then, when the axial force that the core steel plate that consumes energy bears exceedes the yield force that design determines, surrender occurs over just power consumption core steel plate Power consumption segment limit in, and consume energy core steel plate beyond region be in elastic range.Therefore, under geological process, only consume Energy section may produce Plastic Damage, and remainder is remained intact or basic serviceable condition.Meanwhile, consume energy core steel plate soap-free emulsion polymeization Be placed in during constraint system surrounds, after the surrender of pressurized or tension, its power consumption section equably produces plastic strain, can play steady Fixed Hysteresis Behavior.Using the hysteretic energy of power consumption section, the energy of Seismic input structure progressively will be dissipated, so as to reduce earthquake Response.
2) the removable realization of defective component.The construction of the present invention causes the power consumption core easily damaged under violent earthquake Steel plate can be arranged in beyond bean column node, near the position on the upper and lower surface of beam-ends, possess open work surface, and anchor in post Gu being reliably connected between anchor block and power consumption core steel plate in block, beam, due to the design of differential performance-based, in seismic process It is middle to be within elastic range by protection, therefore when needing to change power consumption core steel plate, above-mentioned connection can very easily Release, and do not affect the reuse of anchor block in anchor block in post, beam.Again by the design of differential performance-based, in consumption Can be during core steel plate core segment to be pressurized or tension is surrendered, beam column body does not damage or damages very little, does not affect beam The reuse of post body.So as to, by removing the power consumption core steel plate for damaging, and new power consumption core steel plate is reinstalled, Reach quick reparation structure and recover the purpose of its function.
3) realization of the pressurized anti-buckling mechanism of core steel plate that consumes energy.The core that consumes energy is prevented by way of constraint system is set Amplitude flexing after the pressurized especially pressurized surrender of steel plate outside plane, in plane.In order to prevent constraint system from directly bearing axle To the effect of pressure, the length for constraining system is slightly less than the clear distance in post in anchor block and beam between anchor block, and obligatory point Gap is left between each respective surfaces of system and the core steel plate that consumes energy, so that lateral deflection is especially received when power consumption core steel plate is pressurized After clothes, restrained system is reliably prevented by the amplitude flexing in its face outside dough-making powder, and power consumption core steel plate mainly occurs uniformly Be compressed axially strain.Gap also for consume energy core steel plate it is pressurized when due to caused by poisson effect lateral expansion space is provided. In order to further reduce the friction between power consumption core steel plate and constraint system, also wrap up without viscous around power consumption core steel plate Knot material, non-cohesive material or can fill power consumption core steel plate and constraint system between gap.Such construction, makes power consumption core The for example same small-sized buckling restrained brace of the stress of heart steel plate, the energy dissipation capacity that can be played stably, and there is high ductility.
4) with good tolerance accommodation ability.The component of assembly concrete frame structure in factory's pre-production, so Assembled at the scene afterwards, even if adopt various measures in manufacturing process ensureing the dimensional accuracy of component, the size of component is missed In difference and component, the site error of each part is inevitable.On the other hand, in order to ensure assemble be smoothed out, component it Between must stay and set a certain degree of gap, the collision being just avoided that in assembling process, and the presence in these gaps also causes to install During site error is inevitably present between component and component.Described is applied to assembly concrete frame beam column company The replaceable power consumption coupling assembly for connecing, again by being reliably connected (such as welding) and beam column component phase after beam column installation is in place Even, the tolerance that above-mentioned reason causes can easily be coordinated, it is ensured that the convenience of construction and installation, it is ensured that the reliability of power transmission.
