Description
Technical field
The invention belongs to building antivibration area, is specifically the panel metal damper of a kind of steel-concrete composite slab constraint.
Background technology
For controlling the dynamic response of building structure under wind load and seismic load, usually need employing that mechanical device is set to its vibrational energy that dissipates, thus reach the object reducing vibration and protection agent structure.The vibration isolation of structure is mainly divided into Passive Control, semi-active control, ACTIVE CONTROL and Hybrid mode several.Wherein, Passive Control is the damper having arranged power consumption effect at structure suitable position, and absorption wind or Seismic input, to the energy in structure, reach the effect of reduction and adjust structure dynamic response.Passive Control technology because its simple structure is reliable, energy-dissipating property is stable, cheap, easy to maintenance and be widely used in engineering construction, or for the antidetonation of improving existing old buildings or wind resistance.The passive energy-consumption shock-absorption device adopted in current architecture configuration system is mainly divided into four large classes: viscous damper, metal damper, viscoelastic damper and frcition damper.Metal damper has the features such as stable mechanical property, energy dissipation capacity is strong, low cycle fatigue property is good, has the advantage of simple structure, processing facility, good economy performance concurrently, is widely applied in modern project.
At present mostly metal damper consumes energy with central layer inplane shear surrender, and adopts multi-form stiffening rib to retrain outside the face of power consumption central layer and be out of shape, and central layer is played stably power consumption effect.But because stiffening rib needs to weld with central layer, cause central layer self to produce initial stress and defect, easily obvious impact is caused on the performance of central layer.Due to the restriction such as stability of stiffener itself, specification and the size dimension of damper are greatly limited.And due to stiffening rib, to take part in the shearing of damper to a great extent stressed, makes the design of damper more complicated.For the problems referred to above, there is a kind of mode at present, independently a pair clamping plate are adopted to retrain the out-of-plane buckling of power consumption central layer, prevent the performance of out of plane constraint device to central layer itself from impacting, thus avoid the mutual interference of power consumption and clamping plate out of plane constraint in central layer face, achieve the decoupling zero that central layer design designs with constrained system, performance is more stable, process, design more convenient.
But at present conventional restraining plate is reinforced concrete floor, exists significantly not enough, show: (1), due to the outer stressed impact of needs and face of thickness of protection tier, restraining plate thickness is comparatively large, causes deadweight comparatively large, be unfavorable for the attractive in appearance and lifting installation of building.(2) layer of concrete easily ftractures and collides with damage, requires very high, be unfavorable for quality control and the application of damper to processing technology, transport and lifting mode.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, the panel metal damper of the steel-concrete composite slab constraint that a kind of performance is more stable, quality is better, easy for installation, applied widely is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of panel metal damper of steel-concrete composite slab constraint, comprise metal core board and two pieces of restraining plates, metal core board is sandwiched between two pieces of restraining plates, described metal core board offers some bar shaped vertical cores, the plate status of metal core board is become some bands by bar shaped vertical core; Described restraining plate comprises the layer of concrete of fitting with metal core board, and is coated on the steel box outside layer of concrete.
Further, described restraining plate also comprises stiffening rib, the outer end of stiffening rib and the inner box face of steel box affixed, the inner is stretched in layer of concrete.
Further, described restraining plate also comprises some shear keies, the outer end of shear key and the inner box face of steel box affixed, the inner stretches in layer of concrete.
Further, the two ends up and down of described metal core board are respectively arranged with the L-type junction plate for connecting top and the bottom beam.
The present invention compared with prior art, has the following advantages:
One, metal core board has bar shaped vertical core, the plate status of metal core board is become some bands by bar shaped vertical core, and each band independently consumes energy, and so effectively can improve deformation and the energy dissipation capacity of metal core board, thus improve the damping performance of whole damper; By the adjustment of the quantity to bar shaped vertical core on metal core board, length and width, can realize the Intensity Design in metal core board power consumption design process and the decoupling zero of rigidity Design, effectively can improve versatility, the scope of application is wider.
Two, for restraining plate, steel box can directly as the template of layer of concrete, simple structure, easy construction; Meanwhile, steel box shields to concrete filled, avoids the cracking of inner concrete layer in construction, transport and hoisting process and breakage, thus effectively improves the quality of whole damper.
Three, steel box directly replaces reinforcing steel bar bear, and the thickness of slab having broken away from reinforcing bar Minimal Protective layer limits, and reduces the thickness of restraining plate greatly, and whole damper can do thinner, gentlier, can improve the aesthetic property of building, is convenient to lifting simultaneously and installs.

Detailed description of the invention
Below by drawings and Examples, the present invention is further elaborated.
As shown in Figure 1, Figure 2 and Figure 3: a kind of panel metal damper of steel-concrete composite slab constraint, comprise metal core board 1 and two pieces of restraining plates 2, metal core board 1 is sandwiched between two pieces of restraining plates 2.Metal core board 1 offers some bar shaped vertical cores 23, the plate status of metal core board 1 is become some bands by bar shaped vertical core 23, and each band independently consumes energy.So effectively can improve deformation and the energy dissipation capacity of metal core board 1, thus improve whole damper damping effect.Meanwhile, by the adjustment of the quantity to bar shaped vertical core 23 on metal core board 1, length and width, can realize metal core board 1 and to consume energy the decoupling zero of Intensity Design in design process and rigidity Design, effectively can improve versatility, the scope of application is wider.
