Description
Technical field
It the utility model is related to architectural energy consumption shock-damping structure, more particularly to a kind of light-duty 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, general buckling-restrained energy-dissipation is made 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 energy 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：1. clean steel type buckling restrained brace；2. 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, in a disguised form requires product quality larger for restraint requirement is big, that is, directly results in product
Dead weight 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 the prior art for disadvantages described above, this case.
Utility model content
For disadvantages described above, the utility model provides a kind of light-duty buckling restrained brace, and the constraint support device is by clean steel
Type confinement section and concrete filled steel tube confinement section are for composite, and structure is improved, it is ensured that have preferably buckling-restrained
Outside characteristic, the dead weight of support device itself is also largely reduced, the shock resistance of building is further strengthened, this
Outside, this kind of support device reduces the dosage of raw material, reduces production cost, while is easily installed and dismantles.
To achieve the above object, the utility model uses following technical scheme：
A kind of light-duty buckling restrained brace, including core plate, sleeve, partition plate, slurry, end plate, the core plate include surrender
Section, changeover portion and non-compliant section, core plate middle part are surrender section, and surrender section both ends set changeover portion, then at the setting of changeover portion both ends
Non-compliant section, the main stressed member that core plate is supported as the constraint；Surrender section of the bush outer sleeve in core plate, changeover portion
With on non-compliant section of part, the external constraint component as core plate；The partition plate is arranged at sleeve inner, for dividing core plate
The space retained between sleeve, while limit the out-of-plane deformation of core plate；The filled therewith is in the part that separator lined goes out
In space, further increase constrains the stress intensity of support；The end plate is arranged at sleeve both ends, the envelope as sleeve both ends
Block；
Correspondingly, setting isolated material on the core plate there are filled therewith, for isolating core plate and slurry, facilitate core plate
Dismounting and reuse；
Correspondingly, at least setting a non-slipping block on the core plate there are filled therewith, non-slipping block can be centrally located
It can be symmetrical arranged；
Correspondingly, the end of non-compliant section of core plate can be connected by screw bolts or weld with exterior connection；
Correspondingly, partition plate is fixed on sleeve inner, and partition plate is used for the shape with core plate butted part, be used for core plate and
The profile of partition plate butted part is correspondingly arranged, so that partition plate is fully wrapped around on core plate outer contour；
Correspondingly, partition plate is provided with gap with docking for core plate, which provides space for the yield deformation of core plate；
Correspondingly, set hole on end plate, the cross sectional shape of non-compliant section of the void shape and core plate is identical；
Correspondingly, 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
The non-compliant intersegmental deformation space left when core plate is pulled out and compressed.
The beneficial effects of the utility model are：
The constraint support device is for composite by clean steel type confinement section and concrete filled steel tube confinement section, and structure is carried out
Improve, it is ensured that have outside more preferable buckling-restrained characteristic, the dead weight of support device itself is also largely reduced, to building
Shock resistance is further strengthened, in addition, this kind of support device reduces the dosage of raw material, reduces production cost, at the same time
It is easily installed and dismantles.
