Description
Technical field
The present invention relates to building structure aseismatic prevention technique fields, belong to structural damping and passively control scope, specially entirely
The anti-buckling support of the high ductility of assembled.
Background technology
Traditional anti-buckling support is also known as buckling restrained brace or undonded prestressed concrete.Its main force-mechanism is similar, branch
The core axle power unit of support provides lateral continuous support, without flexing when core cell can be made to be pressurized by external constraint unit
Unstable failure, support axial tension are all up its core section yield force with compression, and the tension and compression bearing capacity of component is close, from
And take full advantage of the intensity of material.Currently, there are two types of the main structural forms of anti-buckling support：（1）Steel tube concrete soil type is anti-
Buckling support,（2）The anti-buckling support of clean steel type is all constructively that core stress unit is placed within constraint element, area
It is not only that the type of constraint element is different.
Anti-buckling support is mainly used for improving the shock resistance of building, and in earthquake, anti-buckling supporting core unit is drawn
After lateral deflection clothes, plastic deformation consumption inputting seismic energy can occur, divide the plasticity energy dissipation capacity that material is utilized, main structure body
Damage energy consumption will reduce, and control the extent of the destruction of building in earthquake, extremely advantageous to earthquake-resistant structure.
The structural form of current anti-buckling support determines that its processing and manufacturing is relative complex, and energy-consuming parts are not after earthquake
It is convenient for changing, it usually needs entire component is removed, waste of material is caused.Importantly, the core of current anti-buckling support
Heart unit is axially loaded component, and limit ductility is substantially directly proportional to the energy consumption length of core cell, and maximum distortion ability is only
Tens millimeters, only several millimeters of yield deformation determines these performance parameters by the physical characteristic of its axially loaded mechanism and steel
It substantially cannot be as needed into accommodating adjustment.In rarely occurred earthquake come when attacking, current anti-buckling support very likely occurs
Because axial limit deformability is insufficient, i.e., ductility is insufficient and there is a phenomenon where fracture failures to exit work.In addition, current is anti-in the wrong
Song support has the also less of plastic deformation recovery capability, though some anti-buckling supports have the function, mostly uses prestress steel
Twisted wire and conversion steel sleeve are realized, cause structurally excessively complicated, actual processing inconvenience, and cost is very high, base in Practical Project
This is seldom used.
Invention content
The present invention is directed to overcome the deficiencies of existing technologies, provides a kind of high ductility of full assembled anti-buckling support, pass through phase
To simply constructing and modular design, the technical barrier that anti-buckling support is faced at present is solved, anti-buckling branch is improved
The application range of support, easy making process, replaces convenience at design flexibility.
In order to solve the above-mentioned technical problem, the invention is realized in this way：
A kind of anti-buckling support of high ductility of full assembled, it is characterised in that：It includes at least two transmitting axle force steel pipes, node company
It connects end plate, axis pin otic placode, axis pin, bending energy-wasting steel plate, middle part steel sleeve and reset reaction spring in arcuate surface；Two axis
Reaction spring is resetted to rigid connection between power transmission steel pipe, the transmitting axle force steel pipe for resetting reaction spring and being connect with its both ends
Two ends be respectively positioned in the steel sleeve of middle part and can opposite sliding；Axis pin otic placode is respectively welded in two transmitting axle force steel pipes
On both sides of the middle, the both ends of bending energy-wasting steel plate are articulated with the axis pin otic placode of two transmitting axle force steel pipes by axis pin in arcuate surface
On, and both ends can relatively rotate in face；Node connection plate is respectively welded at two transmitting axle force steel pipe outer ends.
The anti-buckling support of the high ductility of full assembled, it is characterised in that：It further includes positioning stiffened steel plates, described fixed
Position stiffened steel plates are set between middle part steel sleeve and transmitting axle force steel pipe.
The beneficial effects of the invention are as follows：1, force-mechanism is supported by essential distinction at present anti-buckling：Current is anti-in the wrong
Song support uses steel axial push-pull stress, the present invention to provide rigidity and bearing capacity using the in-plane bending of arch-shaped steel plate item,
Axial bearing capacity is provided by the counter-force for making steel plate occur bending and deformation, and passes to master by the non-compliant elastic lengths of steel pipes at its both ends
Body structure；
2, support performance parameter can be adjusted flexibly, and adapt to different demands：Core of the invention component is arch-shaped steel plate item, makes arch
The external force that steel plate strip is deformed and surrendered can be theoretical by selecting rise, thickness and the span of arch-shaped steel plate item to be adjusted flexibly
Upper its surrender bearing capacity and initial yield deformation can arbitrary combination collocation, greatly breach the performance ginseng of current anti-buckling support
Several restrictions, due to it is modular construction provide facility, can at any time replace, change as needed actual components bearing capacity and
The performance parameters such as yield displacement；
3, with high continuity：The crooked deformability of arch-shaped steel plate item is strong more than the axial deformation ability of steel, the present invention
Ultimate deformation ability can reach 2 ~ 5 times of common anti-buckling support, can meet be not broken under rarely occurred earthquake completely
It is required that；
4, energy consumption section is exposed facilitates observation damage and replaces：Different from the anti-buckling support of casing restricted type common at present, energy consumption
Unit is constrained on inside peripheral cell, and energy consumption unit of the invention is arch-shaped steel plate item, is located at external visibility region, and pass through
Axis pin is connected to stretch section, will not cause the destruction of adjacent linkage section, and can intuitive judgment degree of impairment, only arch is consumed after shake
It can section replacement；
5, internal spring components can provide restoring force, play runback bit function：Spring between two stretch sections, in original state
In free state, internal force is not provided, when after the earthquake, if residual deformation occurs for support, contained spring will be under pressure
Or pulling force, counter-force that spring is provided with deformation direction on the contrary, the afterflow of support can be reduced to a certain extent,
Restore to make the post-seismic deformation of agent structure obtain part, this kind of structural form is than the structure that current self reset curvature-prevention supports
It makes simpler, practical, economical.
6, the present invention is the full articulated constuction of clean steel, convenient for production quick, at low cost：Multiple functions can be achieved in the present invention,
But structurally very easy, each component is substantially mutual indepedent in production, and highly efficient in productivity, standard can be used in partial component
Steel section member further reduces costs.
