Description
Technical field
The present invention relates to architectural energy consumption shock-damping structure, more particularly to a kind of light-duty high-performance buckling restrained brace.
Background technology
Earthquake is a kind of unavoidable natural calamity of human society, casualties caused by earthquake and the big portion of economic loss
Divide and come from building collapsing, therefore countries in the world all are being directed to carrying out earthquake resistant engineering mitigation work.The energy dissipating of building structure subtracts
Shake and refer to set appropriate energy dissipation component in building structure, energy dissipation component can be by energy-consumption shock-absorption device, wall, beam or node etc.
Supporting member forms, and the principle of energy-dissipating support is to increase damping and the rigidity of structure, and the earthquake reduced caused by geological process is anti-
Should, in addition, when agent structure produces interlayer lateral displacement, energy-dissipating support is by stress and energy dissipating, so as to avoid carrying antidetonation
The reinforcing of hypodynamic frame column simultaneously protects agent structure, and rational energy-dissipating support construction is the key for improving anti-seismic performance
One.
In the prior art, in general buckling-restrained energy-dissipation is made up of five parts in the vertical：Constraint surrender section, constraint are non-
Surrender section, without constraint surrender section, soap-free emulsion polymeization expandable material, surrender constraint mechanism.Buckling-restrained energy-dissipation it is various informative, but
Operation principle is substantially similar, i.e.,：Under external force, load is all born by core, and core is in axial tension or pressure for support
Effect is lower surrender power consumption, and peripheral constraint mechanism is supplied to core to bend to limit, flexing when avoiding the core from being pressurized.State at present
Inside and outside buckling restrained brace structural form can be generally divided into two classes：Clean steel type buckling restrained brace；With steel tube concrete
Soil is the buckling restrained brace of constraint element.But existing buckling-restrained energy-dissipation is because its core primary structure member is all by periphery
Constraint mechanism provides bending limitation, and requiring big for restraint in a disguised form requires that product quality is larger, that is, directly results in product
Deadweight it is larger, on the one hand, need to consume more materials in process of production, production cost is high, and there is also all for fabrication and installation
More inconvenient, on the other hand, structure own wt is larger to be unfavorable for damping.
Therefore, effective innovation has been carried out to prior art for disadvantages described above, this case.
The content of the invention
For disadvantages described above, the present invention provides a kind of light-duty high-performance buckling restrained brace, and the constraint support meanss will be pure
Die confinement section and the progress of concrete filled steel tube confinement section are compound, and structure is improved, it is ensured that have more preferable flexing about
Outside beam characteristic, the deadweight of support meanss itself is also largely reduced, the shock resistance of building is further strengthened, this
Outside, this kind of support meanss reduce the dosage of raw material, reduce production cost, while are easily installed and dismantle.
To achieve the above object, the present invention uses following technical scheme：
A kind of light-duty high-performance buckling restrained brace, including core plate, sleeve, dividing plate, slurry, end plate, described core plate include bending
Section, changeover portion and non-compliant section are taken, changeover portion is set, set then at changeover portion both ends for surrender section, surrender section both ends in the middle part of core plate
Non-compliant section is put, the main stressed member that core plate supports as the constraint；Surrender section of the described bush outer sleeve in core plate, transition
In section and non-compliant section of part, the external constraint component as core plate；Described dividing plate is arranged at sleeve inner, for dividing core
The space retained between plate and sleeve, while limit the out-of-plane deformation of core plate；Described filled therewith is in the portion that separator lined goes out
Divide in space, further the stress intensity of increase constraint support；Described end plate is arranged at sleeve both ends, as sleeve both ends
Seal block；
Accordingly, isolated material is set on the core plate for exist filled therewith, for isolating core plate and slurry, facilitates tearing open for core plate
Unload and reuse；
Accordingly, at least provided with a non-slipping block on the core plate for exist filled therewith, non-slipping block can be centrally located can also
It is symmetrical arranged；
Accordingly, the connection of the end of non-compliant section of core plate and outside can be connected by screw bolts or weld；
Accordingly, dividing plate is fixed on sleeve inner, and dividing plate is used for the shape with core plate butted part, is used for core plate and dividing plate
The profile of butted part is correspondingly arranged, so that dividing plate is fully wrapped around on core plate outline；
Accordingly, dividing plate is provided with gap with docking for core plate, and the gap provides space for the yield deformation of core plate；
Accordingly, hole is set on end plate, and the cross sectional shape of non-compliant section of the void shape and core plate is identical；
Accordingly, the hole set on end plate is more than the size of the cross sectional shape of non-compliant section of core plate, i.e. end plate and core plate is non-in the wrong
Take the intersegmental deformation space left when core plate is pulled out and compressed.
Beneficial effects of the present invention are：
The constraint support meanss are compound by clean steel type confinement section and the progress of concrete filled steel tube confinement section, and structure is changed
Enter, it is ensured that have outside more preferable buckling-restrained characteristic, also largely reduce the deadweight of support meanss itself, building is resisted
Shake ability is further strengthened, in addition, this kind of support meanss reduce the dosage of raw material, reduces production cost, while just
In installation and removal.
