Abstract
The invention discloses a damping and restrained brace combined damping energy dissipation device. The damping and restrained brace combined damping energy dissipation device is characterized in that a hysteretic damper and buckling restrained braces are separately and fixedly arranged at the upper part and the lower part of a connecting plate; a box body of which two sides are limiting baffles is buckled on the hysteretic damper; the hysteretic damper and the box body are connected in a sliding way; two buckling restrained braces are fixedly arranged at the lower part of the connecting plate in an equilateral triangle supporting structure form; the connecting plate is arranged between the two limiting baffles and is in interference fit with two collision buffer bodies. Compared with the prior art, the damping and restrained brace combined damping energy dissipation device is simple in structure and convenient to mount; effective energy consumption under different level earthquake actions can be realized; under the action of frequent earthquakes, the energy consumption is buckled by the hysteretic damper; under the action of fortification and rare earthquake, the energy consumption is buckled by the buckling restrained braces; when the hysteretic damper generates greater displacement, the liming can be realized by the limiting baffles, over great displacement is avoided, and the safety of buildings is guaranteed.
Description
Technical field
The present invention relates to architectural engineering cushion technique field, a kind of damping energy-dissipating device damping peace treaty bundle support combinations.
Background technology
Arranging one of the Main Means that displacement type damper is energy-dissipating and shock-absorbing technology in building structure, mild steel damper and buckling restrained brace are the most modal two kinds of displacement type dampers.Mild steel damper generally uses low surrender steel, can preferably realize the power consumption under frequently occurred earthquake effect, and effectively to realize the power consumption under larger earthquake effect, then need steel to have higher ductility simultaneously, design and production to mild steel damper propose higher requirement and challenge.Buckling restrained brace can preferably realize in, power consumption under big shake, but it is under little shake effect, does not the most play power consumption effect.How realizing energy-consumption shock-absorption device effectively power consumption under different earthquake performance standard is one of the problem that need to solve of present stage engineering cushion technique.
Summary of the invention
It is an object of the invention to a kind of damping energy-dissipating device damping peace treaty bundle support combinations designed for the deficiencies in the prior art, use the buckling-restrained shock-damping structure combined with damping, once earthquake and wind load reach or exceed the energy-dissipating and shock-absorbing limit of damper, then continued to play energy-dissipating and shock-absorbing effect by buckling restrained brace, realize the building structure effective power consumption under different earthquake performance standard, guarantee building safety, simple in construction, easy for installation, preferably resolve energy-consumption shock-absorption device problem of effectively power consumption under different earthquake performance standard.
The object of the present invention is achieved like this: a kind of damping energy-dissipating device damping peace treaty bundle support combinations, including mild steel damper, buckling restrained brace, it is characterized in that mild steel damper and buckling restrained brace are respectively fixedly disposed at the upper and lower of connecting plate, fastening both sides on mild steel damper is the box body of postive stop baffle, mild steel damper and box body are for being slidably connected, described postive stop baffle lower end is provided with crusherbull zone body, and crusherbull zone body is connected for fixing with postive stop baffle；Described connecting plate is arranged between two postive stop baffles and is matched in clearance with two crusherbull zone bodies；Described buckling restrained brace is two and is fixedly installed on connecting plate bottom with equilateral triangle supporting construction.
The present invention compared with prior art has simple in construction, easy for installation, it is possible to achieve the effective power consumption under different level geological processes, under frequently occurred earthquake effect, by mild steel damper surrender power consumption, set up defences and under rarely occurred earthquake effect, can consumed energy by buckling restrained brace, when mild steel damper generation larger displacement, can carry out spacing by postive stop baffle, avoid over-large displacement, it is ensured that building safety, preferably resolve energy-consumption shock-absorption device problem of effectively power consumption under different earthquake performance standard.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram；
Fig. 2 is that the present invention specifically uses schematic diagram.
Detailed description of the invention
Refering to accompanying drawing 1, the present invention is made up of mild steel damper 1, buckling restrained brace 2, connecting plate 3 and postive stop baffle 4, and described mild steel damper 1 and buckling restrained brace 2 are respectively fixedly disposed at the upper and lower of connecting plate 3；Fastening the box body that both sides are postive stop baffle 4 on described mild steel damper 1, mild steel damper 1 and box body are for being slidably connected；Described postive stop baffle 4 lower end is provided with crusherbull zone body 5, and crusherbull zone body 5 is connected for fixing with postive stop baffle 4；Described connecting plate 3 is arranged between two postive stop baffles 4 and is matched in clearance with two crusherbull zone bodies 5；Described buckling restrained brace 2 is two and is fixedly installed on connecting plate 3 bottom with equilateral triangle supporting construction.
Refering to accompanying drawing 2, the present invention being arranged in building structure, the box plate of its postive stop baffle 4 is fixing with the beam body of superstructure 6 to be connected, and two buckling restrained braces 2 are fixing with the beam column of substructure 7 respectively to be connected.Mild steel damper 1 uses low surrender type mild steel to make, surrender power consumption is realized when structure occurs less relative storey displacement, buckling restrained brace 2 has higher yield strength, ensure when less relative storey displacement unyielding, as the supporting construction of mild steel damper 1, the surrender power consumption when bearing bigger relative storey displacement, connecting plate 3 has enough rigidity, under rarely occurred earthquake effect, there is not moderate finite deformation and surrender.Soft firm damper 1 and buckling restrained brace 2 lay respectively at the upper and lower of connecting plate 3, both are fixing with connecting plate 3 is connected, preset clearance d between crusherbull zone body 5 and connecting plate 3 that postive stop baffle 4 lower end is arranged, its gap d is the maximum displacement limit value of mild steel damper 1 power consumption effect.Described mild steel damper 1, buckling restrained brace 2, connecting plate 3 and postive stop baffle 1 and gap d need to meet under frequently occurred earthquake effect, and connecting plate 3 does not collides with crusherbull zone body 5, mild steel damper 1 surrender power consumption.Under set up defences earthquake and rarely occurred earthquake effect, when connecting plate 3 and crusherbull zone body 5 do not collide, mild steel damper 1 individually consumes energy, and connecting plate 3 and crusherbull zone body 5 are when colliding, connecting plate 3 is carried out spacing by postive stop baffle 4, avoid the generation of over-large displacement, and carried out surrender power consumption by buckling restrained brace 2, it is ensured that building safety.Present configuration is simple, easy for installation, preferably resolves energy-consumption shock-absorption device problem of effectively power consumption under different earthquake performance standard.
More than simply the present invention is further illustrated, and is not used to limit this patent, all implements for equivalence of the present invention, within being intended to be limited solely by the right of this patent.
