Description
Technical field
The utility model relates to a kind of novel anti-buckling energy-consumption to be supported, and belongs to technical field of structural engineering.
Technical background
Japan's slope shake celestially with the mountain range earthquake of U.S. north after, anti-buckling energy-consumption supports the energy-dissipating and shock-absorbing member as a kind of superior performance, has obtained applying fast in the developed countries of many shakes such as Japan-US grade.Anti-buckling energy-consumption supports to be made up of kernel and peripheral two parts: inner core component directly bears the axial load effect, the general steel that adopt low-yield, why adopt the steel of low-yield, be to wish that anti-buckling energy-consumption supports and can enter surrender prior to framework under middle shake and big shake, thereby improve the ductile performance of structure and give full play to the power consumption effect of support; Peripheral constraint component is not directly born the axial compression effect, but it can improve the flexing load of inner core component to the effect of contraction of inner core component, make kernel portion that the total cross-section surrender take place under the external pressure effect, thereby improve the plumpness of member hysteretic loop and the energy dissipation capacity of member.
Anti-buckling energy-consumption supports and has " support " and " power consumption " two kinds of effects concurrently, is a kind of good energy-dissipating and shock-absorbing member that shows under geological process.Under little shake effect, anti-buckling energy-consumption supports and keeps elasticity, thereby for agent structure provides enough rigidity, guarantees that the sidesway of main body frame meets the demands; Under middle shake and big shake effect, anti-buckling energy-consumption supports and enters surrender, and by the surrender dissipation seismic energy of nuclear cross section in it, thereby the safety of protection main body frame is also effectively subdued earthquake response.
The anti-buckling energy-consumption support still is in the starting stage in China, the anti-buckling energy-consumption that China generally adopts on engineering at present supports, form by peripheral concrete filled steel tube and kernel steel plate mostly, kernel steel plate will brush one deck non-cohesive material, and and fill concrete between leave certain space, to prevent the pressurized dilatancy of peripheral concrete filled steel tube constraint kernel steel plate, manufacturing process is comparatively complicated, cost of manufacture is higher, and is unfavorable for realizing industrialized mass production.If less demanding, can adopt " one " font kernel usually to the yield load that anti-buckling energy-consumption supports; Higher if desired yield load, " worker " font kernel that then adopts three blocks of plates to be welded into usually, and the process of welding is bigger to the influence of steel wood property, can have residual stress and cause material around to become fragile, and anti-buckling energy-consumption supports and can just rupture under the few tension and compression circulation of number of times.
For overcoming the above-mentioned shortcoming that common anti-buckling energy-consumption supports, the utility model proposes a kind of brand-new assembling anti-buckling energy-consumption supports, it utilizes bolt that two " huge " font fastener set are lumped together as peripheral constraint component, utilize hot rolled H-shaped as the kernel primary structure member, thereby obtain a kind of low cost, high efficiency energy-dissipating and shock-absorbing member.Under geological process, hot rolled H-shapedly when pressurized, can reach total cross-section surrender, and flexing does not take place, this all is very favourable to the control earthquake malformation down diffusing seismic energy of becoming reconciled.Also to leave certain clearance between kernel that this anti-buckling energy-consumption supports and the periphery, but its gap is present between " huge " font fastener and the kernel, be the gap between steel and the steel, rather than the gap between concrete and the steel, machining accuracy is easy to satisfy; In addition, this anti-buckling energy-consumption supports the profit facility of drawing materials, and material cost is lower; Most operation can be finished in processing factory, and member is transported to the job site assembly unit and gets up to get final product, and site operation is very convenient simple; It utilizes H shaped steel as the kernel pressure-containing parts, and ductility is fine, and yield load can reach bigger tonnage; It is positioned over the periphery of kernel portion with confining part, thereby has realized the maximization of cross section efficient.
The utility model content
" huge " font fastener restricted type assembling anti-buckling energy-consumption that the utility model proposes supports, purpose is to provide a kind of brand-new fabricated support energy dissipation component, for main structure body provides the lateral resisting effect, and effectively power consumption under big shake effect, subdue geological process; Aspect the formation that supports at anti-buckling energy-consumption, the outstanding feature that anti-buckling energy-consumption of the present utility model supports is, kernel adopts hot rolling H shape steel, and the welding compound section kernel that supports compared with common anti-buckling energy-consumption has higher ductility and better energy dissipation capacity; In addition, this anti-buckling energy-consumption supports and adopts the combination light gauge cold-formed steel shape as peripheral constraint component, and is arranged in around the kernel portion, has realized the maximization of cross section load-carrying efficiency.
About beam ratio is the important parameter that anti-buckling energy-consumption supports, and it is the ratio that anti-buckling energy-consumption supports integral, flexible flexing load and kernel yield load, promptly
It has reacted the power of peripheral constraint portions to the effect of contraction of kernel.By rational about beam ratio is set, can guarantee the operate as normal that anti-buckling energy-consumption supports." huge " font fastener restricted type assembling anti-buckling energy-consumption that proposes for the present invention supports, and gets about beam ratio between 1.8-2.0, can guarantee that the periphery has enough effect of contractions.
" huge " font fastener restricted type assembling anti-buckling energy-consumption that the utility model proposes supports, it is characterized in that: contain " huge " font fastener and hot rolled H-shaped, wherein " huge " font fastener has two: first " huge " font fastener (1) and second " huge " font fastener (2), described each " huge " font fastener is welded mutually by a hat light gauge cold-formed steel shape and the grooved light gauge cold-formed steel shape that is embedded in this hat light gauge cold-formed steel shape inboard, concrete perfusion in the sealing rectangular tube that forms by described hat light gauge cold-formed steel shape and grooved light gauge cold-formed steel shape, described first " huge " font fastener (1) fastens at the marginal ridge place in the relative mode in inboard with second " huge " font fastener (2), and connects with bolt at described fastening place; Hot rolled H-shaped, be arranged in described first " huge " font fastener (1) and second " huge " font fastener (2) and fasten " H " figure space that the back forms, constitute inner core component; At described first " huge " font fastener (1), these two fasteners of second " huge " font fastener (2) with describedly leave the gap, the cross section dilatancy that produces in order to prevent described peripheral member from retraining described inner core component pressurized between hot rolled H-shaped.
