Description
Technical field
The utility model relates to a kind of channel-section steel and combines anti-buckling support, specifically the anti-buckling support of channel-section steel combination filled-type twin-core.
Background technology
Earthquake is the natural calamity that a kind of randomness is very strong, brings grave danger can to people's the security of the lives and property, can only be prevented by technological means, reduces to greatest extent the loss that it causes.The Damage mechanism of building in earthquake is, inputting seismic energy is converted into deformation energy and the kinetic energy of structure, while surpassing its elastic limit, will there is Plastic Damage in malformation, Plastic Damage is accompanied by energy consumption, if the seismic energy that structure dissipates by damage is not enough to consume the energy of earthquake input, structure can not be resisted this earthquake so, and destruction immediately collapses.
Anti-buckling support is a kind of antidetonation new technology, and it is arranged on original structure, can be used as additional dissipative member; prior to main structure body, enter plastic state, dissipation inputting seismic energy, can be described as structural seismic " fuse "; and after shake, can change, can protect to greatest extent main structure body.
The operating principle of anti-buckling support and force-mechanism are very clear and definite, by restraining tube unit constraint axially loaded steel member, guarantee that whole unstable failure and local buckling failure do not occur when pressurized for it, axle power member will show the good mechanical property of tension and compression symmetry in earthquake so, and surrender a large amount of dissipation inputting seismic energies by this tension and compression, it is a kind of of metal energy-consumption shock-absorption device.
At present, anti-buckling support mainly contains two large classes: the anti-buckling support of (1) concrete filled steel tube filled-type; (2) the anti-buckling support of clean steel type.The anti-buckling support of concrete filled steel tube filled-type; can utilize the bending rigidity of concrete filled; the steel using amount supporting can be reduced greatly; but the production process of external constraint steel bushing is comparatively loaded down with trivial details; due to welding deformation reason; often can cause flat appearance degree not enough, the phenomenons such as Concrete Filled leakiness, the concrete curing cycle is also longer.Although and the anti-buckling support deadweight of clean steel type is lighter, process velocity is fast, owing to only relying on the bending rigidity of steel bushing to prevent its unstable failure, has inevitably increased the consumption of steel and the apparent size of support, the corresponding lifting of cost meeting is a lot.
In addition, the power consumption core section of current anti-buckling support common are the forms such as " one " font, " ten " font, " work " font, and the core of " one " font section does not have welding residual stress, and initial imperfection is less; And the core of " ten " font and " work " font section in group immediately, inevitably to carry out welding operation to power consumption core, and then produce initial stress and defect, by the low cycle fatigue property that greatly impact is supported.
Summary of the invention
The utility model is intended to overcome the defect of prior art, provides a kind of channel-section steel combination filled-type twin-core anti-buckling support, has simplified processing technology, has improved product quality and process velocity; Its two " one " font cores that adopt have not only promoted the low-cycle fatigue energy dissipation capacity supporting, and can make bearing capacity do more, and have further improved the utilization rate of material; It adopts the node connected mode of " work " font, has guaranteed that support node is in elastic state.
In order to solve the problems of the technologies described above, the utility model is achieved in that
The anti-buckling support of channel-section steel combination filled-type twin-core, is characterized in that: it comprises two yi word pattern steel cores and constraint steel casing, and two yi word pattern steel parallel core settings are also positioned at constraint steel casing, and constraint steel box house is filled with concrete; Described constraint steel casing comprises four steel plates of putting more energy into, two the first junction plates, a pair of channel-section steel, some batten plates and two the second junction plates, four steel plates of putting more energy into are welded on respectively the two ends of two yi word pattern steel cores, welding the first junction plate in the middle of two relative steel plates of putting more energy into; A pair of channel-section steel is oppositely arranged, they be positioned at two yi word pattern steel cores outside, with yi word pattern steel parallel core; This,, to being welded to connect by several batten plates between the side plate inwall of channel-section steel, is welded to connect by the second junction plate is elongated between side plate outer wall.
The anti-buckling support of described channel-section steel combination filled-type twin-core, is characterized in that: described in the put more energy into width of steel plate the inner identical with yi word pattern steel core, the width of the steel plate outer end of putting more energy into is greater than the width of yi word pattern steel core.
The described anti-buckling support of channel-section steel combination filled-type twin-core, is characterized in that: the flakiness ratio of described yi word pattern steel core is not more than
, f wherein
yfor steel yield strength.
The beneficial effects of the utility model are: before the surrender of power consumption core, can be structure larger anti-side rigidity and supporting capacity is provided, it acts on same conventional steel brace, but because the utility model whole unstable failure can not occur, material use efficiency is higher; A large amount of inputting seismic energies that can dissipate after the surrender of the utility model power consumption core, for structure provides additional damping, are a kind of metal dampers of function admirable; The mode that adopts channel-section steel and junction plate welding to form constraint steel casing has reduced welding capacity, is convenient to standardized production and guarantees product appearance, has reduced cost of manufacture, has improved process velocity; Adopt two " one " font cores, promoted its low cycle fatigue property, improved supported design tonnage and stock utilization.The utility model also has the advantages such as processing cost is low, good in economic efficiency, easy construction.
