Specific embodiment
Embodiment: a kind of anti-buckling support, including energy consumption inner core 1, baffle 5, connecting plate 6 and constraint outer sleeve 7, constraint are outer
Sleeve 7 covers the periphery for being connected to energy consumption inner core 1, and the both ends of energy consumption inner core 1 extend outward constraint outer sleeve 7, and are connected by baffle 5
It connects on connecting plate 6, constraint outer sleeve 7 has one group of opposite and parallel horizontal interior wall, and energy consumption inner core 1 is in parallel, energy consumption
1 quilt cover of inner core connects in the space between the inner wall of the part constraint outer sleeve 7 corresponding with the part inside constraint outer sleeve 7
Anti- unstability device is reversed in installation.The energy consumption inner core of the part, for tool there are two side, each side is corresponding to constrain the interior of outer sleeve
Anti- unstability device is reversed in installation between one side of wall, i.e. horizontal interior wall, i.e. a horizontal interior wall and an energy consumption inner core；The torsion
Turning anti-unstability device includes torsionspring 2, limiting card 4 and guiding iron staff 3, and the guiding iron staff 3 is perpendicular to energy consumption inner core 1
Run through energy consumption inner core 1 on axial direction, and be fixed in energy consumption inner core 1, is oriented to the exposed two sides in the space of iron staff
It is covered and is connect thereon by torsionspring 2, the spring arm of force of connection 2 ontology of torsionspring is limited the limit of card 4 respectively and turns round in torsionspring 2
The inner wall of the constraint outer sleeve 7 of the upper and lower two sides of the twisted planar formed when turning.
In one embodiment, the anti-unstability device of the torsion is mounted on 1 quilt cover of energy consumption inner core and connects in constraint outer sleeve 7
In space between the inner wall of the part at internal both ends constraint outer sleeve 7 corresponding with the part at the both ends, You Shangyi
Embodiment could be aware that nearby space all has the possibility for installing energy consumption unstability device to entire energy consumption inner core, however, practicing
In, it has been found that it is more proximate to the initial position of load transmission, and corresponds to the end position of position in fact, i.e. energy consumption inner core
Space near two terminals forms twisted planar using torsionspring, needs the correction demand to energy consumption inner core stronger, and
And two positions are grasped, it can start to correct in source, not make displacement transfer, as far as possible so as to further decrease
The section of deformation inhibits the ability of deformation stronger.
Further, in general, energy consumption inner core is understood some and is in outside constraint outer sleeve, should be partially due to straight
Connect it is exposed, compare in constraint outer sleeve inside energy consumption inner core, due to it is unfettered and support, it is more weak, easily occur break
It is bad.Using anti-unstability device is reversed, guiding iron staff therein is combined with the limit of torsionspring, so that the displacement of the lines of energy consumption inner core
It is changed into angular displacement, also, reverses anti-unstability device and be in end nearby (being close to exposed energy consumption inner core part), to makes
Iron staff must be oriented to can form frame in the exposed energy consumption inner core part, have certain supporting role, and reversed
The twisting resistance of spring greatly reduces movement (rock and swing) of the exposed part under load effect on the basis of support,
So as to shorten to join domain range, the program realizes the purpose for preventing unstability.
In this embodiment, the energy consumption inner core 1 is the cuboid of strip, is plugged on the pact that shape is long cylinder rectangle
In 7 inside of beam outer sleeve, and central position is essentially in two horizontal interior walls, the iron staff is through energy consumption inner core 1 and is in
Two sides are symmetrical, and the restraining position of 2 installation site of torsionspring and its spring arm of force is centered on by perforative energy consumption inner core 1
And it is symmetrical.Central symmetry setting, so that the reaction force of two twisted planars is more consistent, for distortion correction, and torsion
The equal better effect of plane energy consumption.
In one embodiment, the torsionspring of marmem by being made.The torsionspring is served as reasons
Helical spring and the arm of force composition for being connected to helical spring both ends.The super elastic characteristics of marmem and other common gold
Category material, which is compared, to be had many advantages: the fatigue properties of super elastic shape memory alloy first are fine, and in other materials circulation not
It damages avoidablely, influences the service life；Secondly marmem recoverable strain value is very big, and ordinary metallic material is difficult to reality
Existing；Finally, due to which Ovshinsky bulk modulus is greater than geneva bulk modulus, shape memory alloy elastic modulus is increased with temperature
And increasing (opposite with common metal), this makes it still keep high elastic modulus at relatively high temperatures.Therefore, shape memory is utilized
Alloy can be fabricated to the spring section of the device.
Anti-buckling support described in above-mentioned each example, under geological process, energy consumption inner core is come by from building transmitting
Load, energy consumption inner core is deformed, and energy consumption inner core drives torsionspring to deform by the guiding iron staff being fixed thereon, and reverses bullet
Spring planar generates torque, and torsionspring is limited in the upper and lower two sides of the twisted planar formed when torsionspring torsion, turns round
The torsion for turning spring drives energy consumption inner core to result from the opposite movement of deformation direction, makes shape of the energy consumption inner core to nature when
And position is replied.
Anti-buckling support in each example as a result, in order to mitigate vibration to structure function, for the anti-buckling support of tradition, opposite end
Portion carries out unstability and reinforces design, slows down the impaired of inner core.In the case of seismic events, enabling capabilities are improved.Utilize marmem
It is made into torsionspring, device is anti-buckling support energy consumption inner core, torsionspring, outer sleeve upper limit card co-operation, is made
It slows down the impaired of inner core with certain runback bit function.Torsionspring belongs to helical spring, and the end of torsionspring is fixed
To other assemblies, when other assemblies are rotated around spring center, which retracts initial position for them, generates torque or rotation
Turn power.Torsionspring can store with separation angle energy or by fixing a certain dress around the spring body middle shaft rotation arm of force with static state
It sets.Limiting card can limit torsionspring position, can play the role of fixed spring, while can also play limitation bonding material
The effect of material, inner core.The device is simple to operation can be connected by way of assembling, convenient disassembly and after facilitating shake
Reparation and daily maintenance.
Under geological process, energy consumption inner core will receive the load come from building transmitting, and inner core can be deformed, inner core
Torsionspring deformation is driven, torque, torsion with higher are planar generated.Due to the presence of inner core limit card slot, generate
Torsion will drive inner core movement, so that it is returned to original position, therefore device has runback bit function.Structure is by earthquake
When effect, no matter end makes to realize Self-resetting by the restoring force of torsionspring in compression or tension, in reduction
The compressive deformation of core improves energy dissipation capacity and also ensures monolithic stability after inner core surrender, do not influence normally to support.
The preferable specific embodiment of the above, only the invention, but the protection scope of the invention is not
It is confined to this, anyone skilled in the art is in the technical scope that the invention discloses, according to the present invention
The technical solution of creation and its inventive concept are subject to equivalent substitution or change, should all cover the invention protection scope it
It is interior.
