Description

A kind of high-performance supporting member based on Self-resetting energy consumption
Technical field
The present invention relates to Construction Anti-earthquakes and cushion technique field, and wide frequency can be provided in shake more particularly, to one kind Domain is consumed energy, the high-performance supporting member of Self-resetting after shake.
Background technology
Support system is that building structure is resisted including earthquake and one of the important component of lateral force including wind load.Currently Design object allow generally for being supported on that big shake is lower that elastic-plastic deformation occurs, therefore to the deformation of supporting member and its connecting portion Performance and bearing capacity propose high requirement.Although traditional flexible support can provide lateral rigidity by tensile strength, It is gradually to be failed in earthquake due to constantly surrendering, generates idle running effect, lose energy dissipation capacity.Meanwhile flexible support exists Plastic deformation under geological process can be concentrated at position of joints, including screw hole and the gaily decorated basket position of tensioning, but the position Material, which may be because, not to be had enough ductility and shear lageffect and is easily broken, so as to cause catastrophic consequence. Although the buckling restrained brace risen recently can provide larger lateral rigidity and energy dissipation capacity, the institute after middle shake or macroseism Caused plastic deformation is difficult to repair, while may be lost if permanent deformation is excessive using the structure of buckling restrained brace The feasibility of reparation, to make total be forced to remove after shake.
Chinese patent ZL 201310602995.4 discloses a kind of circumferential viscous damping support.It include upper bearing plate and Lower support plate, is equipped with bearing weight body between the upper bearing plate and lower support plate, the upper bearing plate side edge extends downwardly simultaneously It bends inwards to form annular housing, bearing weight body top is cased with annular piston, is cavity structure, institute inside annular piston State that annular piston upper and lower ends face is bonded the upper inner wall of annular housing respectively and lower inner wall seals annular housing, the annular chamber Internal portion is connected to the cavity of annular piston, and viscous liquid is filled in the annular housing.This viscous damper is transported in high frequency Has the effect of preferable oscillation damping and energy dissipating when dynamic, but the energy consumption under high temperature and low-frequency vibration is then apparent insufficient.
Invention content
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind to be consumed based on Self-resetting The high-performance supporting member of energy.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of high-performance supporting member based on Self-resetting energy consumption, including Self-resetting energy-consuming parts, and be separately mounted to The body supports cylinder at Self-resetting energy-consuming parts both ends also carries end-fitting, the Self-resetting on the body supports cylinder Energy-consuming parts include outer barrel and piston guide rod, and viscous damper chamber and marmem cup spring group are additionally provided in the outer barrel One end of chamber, the piston guide rod sequentially passes through viscous damper chamber and marmem cup spring group chamber, and the other end is fixed A body supports cylinder is connected, the outer barrel is also fixedly connected with another body supports cylinder;
When vibration occurs, piston guide rod moves back and forth in outer barrel, and the damping liquid of viscous damper intracavitary is to piston Guide rod provides resistance, meanwhile, piston guide rod squeezes the marmem cup spring for being placed on marmem cup spring group intracavitary Group realizes oscillation damping and energy dissipating.
The viscous damper chamber includes the viscous damper cylinder being fixed in outer barrel, and resistance is filled in viscous damper cylinder Buddhist nun's liquid, the piston guide rod pass through viscous damping cylinder, are always positioned on the part in viscous damping cylinder also in piston guide rod It is arranged at least one piston, the throttle orifice to circulate for damping liquid is also distributed on piston.
The outer ring surface of the piston contacts sealing with the inner cylinder wall surface of viscous damping cylinder.
The viscous damper cylinder includes the viscous damper barrel for being close to outer tube inner wall, in viscous damper barrel The opening at both ends is also sealed and installed with damper cover board, and damper cover board is also fixedly connected with outer tube inner wall, the piston Guide rod sequentially passes through two pieces of damper cover boards, and sealing is kept between the piston guide rod and damper cover board.
The marmem cup spring group chamber includes the cup spring group chamber cylinder being fixed in outer barrel, in cup spring group chamber cylinder Marmem cup spring group is installed, the piston guide rod passes through cup spring group chamber cylinder and marmem cup spring group, institute The position limiting structure for being respectively held against marmem cup spring group both ends is also formed on the piston guide rod stated;
When piston guide rod moves back and forth in outer barrel, the position limiting structure at both ends, which is alternately squeezed with the cooperation of cup spring group chamber cylinder, to be located at Intermediate marmem cup spring group realizes oscillation damping and energy dissipating.
The marmem cup spring group includes multiple hard inner ring and marmem outer shroud, hard inner ring The internal face of outside wall surface and marmem outer shroud is provided with the chamfer being mutually matched, and is remembered by hard inner ring and shape Recall the extruding that contacts with each other between the chamfer of alloy outer shroud, button takes a shape between realizing per two adjacent hard inner ring Memorial alloy outer shroud.
It is also separately installed with one piece of gasket in two hard inner ring of outermost end in marmem cup spring group, and Meet:When piston guide rod moves back and forth, by resisting the gasket come extrusion shapes memorial alloy cup spring group.
The hard inner ring is smart steel inner ring.
The piston guide rod is being recessed abrupt change of cross-section slot, the shape at marmem cup spring group The inner opening diameter of memorial alloy cup spring group is matched with abrupt change of cross-section slot, and the both ends of abrupt change of cross-section slot is made to form described be used for Resist the position limiting structure at marmem cup spring group both ends.
The cup spring group chamber cylinder includes cup spring group chamber barrel and cup spring group chamber lid plate, and the cup spring group chamber barrel is close to On outer tube inner wall, the cup spring group chamber lid plate is used to seal the opening of cup spring group chamber barrel, and fixes and connect with outer tube inner wall It connects.
The high-performance supporting member based on Self-resetting energy consumption of the present invention, collection lateral resisting, anti-buckling, Self-resetting, wide frequency domain The important function of seismic resistance such as energy consumption are in one.Wherein, Self-resetting energy-consuming parts utilize viscous damping system and super-elastic shape memory Alloy cup spring group carries out joint energy consumption, and the marmem cup spring group energy consumption feature unrelated with loading frequency is utilized, improves Consume energy insufficient disadvantage under viscous damper low frequency.The Self-resetting performance of marmem cup spring group is utilized simultaneously, protects Nothing needs to change after card supporting member shake.
