The anti-buckling supporter disclosed by the utility model has the length of 10-50m and the slenderness ratio of 30, and can be used in a large power plant air cooling platform structure, a large and special industrial building, a large-space structure and some high-rise buildings, structural rigidity and the functionality of the building can be improved, and a major structure can be protected through inhouse yield energy consumption under design intensity, rare intensity and even oversized earthquakes.
Description
Technical field
The utility model belongs to civil engineering structure energy-dissipating and shock-absorbing (shaking) technical field, is mainly used in civil structure engineering, structural engineering.Suit in large power plant air cooling platform structure, large-scale and special industry building, large spatial structure and some highrise building, to install and use.
Background technology
The anti-flexing that some is set between the important node of civil engineering structure system supports and can replace common support; Can prevent pressurized flexing phenomenon, reaching increases the anti-side rigidity of structure, earthquake energy, raising shock resistance, effectively protects the effect of structure and facility.It is a kind of energy-dissipating and shock-absorbing member that anti-flexing supports, and hysteresis loop is full, can make structure obtain big damping ratio, reduces geological process; Also can change the power transmission rule of structural system, alleviate the seismic shear that other lateral resistant member is born; When earthquake takes place, also can a large amount of non-resilient sex change be received in anti-flexing supporting sleeve inside, be that agent structure is in elasticity, accurate elastic stage, the energy-dissipating and shock-absorbing effect is excellent.If also replaceable, and do not influence the normal use of structure through big damaged evil idea.
Common anti-flexing bearing length scope does not wait from 3 meters to 20 meters; Though can satisfy the needs of general building structure energy-dissipating and shock-absorbing, in special industry building such as large power plant air cooling platform structure, large-scale hangar, field, Large-scale Railway station or large spatial structure and some highrise building, use anti-flexing and support the energy-dissipating and shock-absorbing technology and be greatly affected.Making the bigger anti-flexing of length and support, mainly is the restriction that receives aspects such as steel core mother metal size (like hot-rolled profile, sheet material), machining (like the milling machine cutting) condition, on-the-spot lifting (lifting capacity and lifting requisite space) condition.Surpass 20 meters or slenderness ratio and surpass 30 overlength member and make length, be difficult to especially realize.
The utility model content
The utility model provides a kind of multistage and connect the anti-flexing support structure of overlength yardstick, length can reach 20～50 meters, and the anti-flexing of 10～20 meters length supports and also can adopt, and slenderness ratio can reach 30.Under the precondition that guarantees to provide endurance and stiffness to satisfy works operate as normal demand and energy-dissipating and shock-absorbing, solved because of section bar, problem that machine and construction and installation ran into, for wind resistance, vibration damping, energy-dissipating and shock-absorbing provide selectable product.
In order to realize above-mentioned effect, the utility model designs a kind of multistage and connects the anti-flexing support of overlength yardstick, and it is characterized in that: anti-flexing supports and comprises a plurality of segmentations; Each segmentation comprises steel core, is wrapped in the concrete of filling out in the steel sleeve, steel sleeve of steel core active section outward; And being in the flexible material between steel core and the concrete filled, each segmentation is carried out butt welding and is connected combination in the Butt Section, the steel core surface flexible material of mating formation; Assembling butt joint closed casing, concrete filled and sealing.Each combined section connects to flute profile weld bond and Butt Section vertical channel-shaped weld bond through the Butt Section level in the Butt Section; The Butt Section level staggers on the vertical channel-shaped weld bond position to flute profile weld bond, Butt Section each other, and is arranged within the Butt Section that is in beyond the active section cutting arc scope.
The steel core of the utility model can consume energy under design control displacement in surrender, and the flexing unstability does not take place.The flexible material of on steel core surface, mating formation, thickness are confirmed by design, in order to reduce the friction between steel core and constraint element, guarantee steel core dilatation smoothly, obtain outstanding hysteretic energy performance.Certain Butt Section, the middle part of the utility model has the double action of butt joint and spacing card, can guarantee the position relative fixed between steel core and the constraint element, and spacing card does not need to be provided with separately.The utility model can adopt that bolt connects, hinged, welding, or partly welds multiple connected mode such as half bolt connection and be connected with the key node of agent structure.
Compare with existing anti-flexing support technology, the utility model adopts sectional making, field joint assembling, on-site hoisting to connect, and can produce and install smoothly the anti-flexing support product of mesoscale, overlength yardstick (10-50 rice).Surrender bearing capacity, elastic stiffness and elastoplasticity rigidity can be controlled by design.For functional, the adjustment structural weak position of improving large scale structure, subdue seismic energy, reduce earthquake response and have obvious effect.
