Description
Technical field
The utility model relates to a kind of novel buckling-restrained power consumption to be supported, and belongs to engineering structures power consumption buckling restrained brace field.
Background technology
Braced frame structure has solved pure frame structure excessive problem of side direction displacement under earthquake and high wind load action, therefore in building structure, and especially extensive use in the high building structure.But the normal tape support frame structure supports during pressurized under severe earthquake action and produces easily the flexing phenomenon, the destruction or the inefficacy that very easily cause support itself or connect, support simultaneously the hysteretic energy ability variation after the flexing, be difficult to effective power consumption, thereby the shock resistance of structure is reduced.For solving the problem of common support pressurized flexing, from the seventies in last century, India, Japan and the U.S. develop respectively various buckling-restrained power consumptions and support, double steel plate core buckling-restrained energy-dissipation such as people's developments such as the steel sand pulpboard buckling-restrained energy-dissipation of people's developments such as traditional buckling restrained brace, village's well of the people such as Watanave development be just quick, Cai Kequan, the shortcoming of having improved traditional supporting member flexing when pressurized is supported in these buckling-restrained power consumptions, not only realized the supporting member function of traditional support, and be a kind of energy dissipation component of superior performance.
The core cell of tradition buckling restrained brace is steel plate, and constraint element is interior back-up sand slurry or concrete rectangular steel tube.A large number of experiments show that interior back-up sand slurry or concrete can provide operative constraint for the core cell steel plate, so energy-dissipating property is excellent.Take traditional buckling restrained brace of the people such as Watanave development as the basis, develop various interior back-up sand slurries or concrete and support as the buckling-restrained power consumption of core cell constraint component.Interconnect as buckling restrained brace with the U-steel of filling mortar in two such as the just quick steel sand pulpboard buckling-restrained energy-dissipation that waits people's development of village's well, the double steel plate core buckling-restrained energy-dissipation of the people such as Cai Kequan development independently partly forms by two, and each part has core cell and interior back-up sand slurry or concrete rectangular steel tube constraint element.Above-mentioned buckling-restrained power consumption is supported and is all had in various degree the excessive problem of deadweight, has also increased to a great extent dead load in the energy dissipation capacity that improves support and structure.The people such as Cai Kequan improve double steel plate core buckling-restrained energy-dissipation, although the buckling-restrained power consumption support of the double-core all steel type weight reduction of developing, complex structure, production process is loaded down with trivial details.In addition, the sectional dimension of the core cell that above-mentioned various buckling-restrained power consumptions are supported has sudden change, so stress is concentrated and become an outstanding problem that needs to be resolved hurrily.
In a word, although over nearly 40 years, buckling-restrained power consumption supporting to develop has gone out so multiple types, excessive, the complex structure of conducting oneself with dignity, some position the problem that stress concentrates occurs easily and are not still effectively solved.Therefore, in the urgent need to develop a kind of light and handy, simple structure, cheap and cross section is supported without the novel buckling-restrained power consumption of sudden change.
Summary of the invention
The purpose of this utility model is: provide a kind of light and handy, simple structure and cross section to support the cheap function that effectively realizes its support and power consumption without the novel buckling-restrained power consumption of sudden change.
The utility model is that the buckling-restrained power consumption of a kind of Novel bamboo joint type steel pipe is supported, comprise: core cell core pipe (3), internal constraint unit and external constraint unit is characterized in that: described external constraint unit is comprised of outer sleeve (1) and outer tube (2) from outside to inside successively.
Described internal constraint unit is comprised of inner sleeve (4) and the real in-core collar (5) interval successively from supporting end to end.
Described outer sleeve (1), outer tube (2), core pipe (3), inner sleeve (4), the real in-core collar (5) are the rectangular steel pipe cross section.

2. from heavy and light.Outer sleeve of the present utility model (1), outer tube (2), core pipe (3), inner sleeve (4), the real in-core collar (5) and bearing (7) are steel, and inner sleeve (4) inner hollow, even if in the larger situation of sectional dimension, adopt follow-on buckling-restrained power consumption to support, increase cross inner support (6) in the inner sleeve (4), perhaps outer tube (2) and core pipe (3), regeneration concrete can be filled in gap between core pipe (3) and the inner sleeve (4), rubber concretes etc., still relatively traditional buckling restrained brace is lighter in the deadweight that buckling-restrained power consumption is supported.
3. simple structure.During installation need only with between inner sleeve (4) and the real in-core collar (5) in being installed in core pipe (3), outer tube (2) is installed outside core pipe (3) again, outer sleeve (1) then is installed outside outer tube (2) at a certain distance, at last bearing (7) is connected to core pipe (3) two ends, can finishes assembling of the present utility model.
4. unstressed concentration problem.The utility model core pipe (3) is elongated without the abrupt change of cross-section, has therefore avoided existing various buckling-restrained power consumptions to support some position and the problem that stress is concentrated occurred easily.
Cheap, be suitable for the processing of factory streamline.Can be widely used in the newly-built and strengthening and rebuilding engineerings such as high level, towering structure, road and rail bridge, to increase the structural entity energy dissipation capacity, reach the purpose of protection against and mitigation of earthquake disasters.
