Abstract

The utility model relates to the technical field of quake prevention and disaster prevention for building structures, in particular to an energy consumption quake reduction device. A self-resetting metal shearing damper comprises a square frame, an energy consumption steel plate arranged in the square frame, a pair of channel steel arranged on the left side and the right side of the energy consumption steel plate and two high-strength pre-stress steel cables. The square frame is formed by an upper connecting plate, a lower connecting plate, a left connecting plate and a right connecting plate, wherein the upper connecting plate, the lower connecting plate, the left connecting plate and the right connecting plate are provided with bolt holes. An upper side and a lower side of the energy consumption steel plate are fixed with the upper connecting plate and the lower connecting plate respectively in welding mode. Two ends of the channel steel are connected with the left connecting plate and the right connecting plate in welding mode, and the inner sides of the channel steel butt again the energy consumption steel plate. The two high-strength pre-stress steel cables are arranged in the square frame in crossing mode, and two ends of the two cables penetrate through the left connecting plate and the right connecting plate to be anchored on outer walls of the left connecting plate and the right connecting plate. By means of the pre-stress steel cables, residual deformation after an energy consumption device is yielded and deformed can be recovered, and residual deformation of the shearing damper after an earthquake is improved and reduced.

Description

A kind of Self-resetting metal sheet slitting damper
Technical field
The utility model relates to building structure aseismatic prevention technique field, relates in particular to a kind of energy-consumption shock-absorption device.
Background technology
Traditional structure design is by the key structure members such as beam, post, support opposing geological process.This design concept will cause important structural element to enter surrender power consumption state inevitably in earthquake, and it back and forth under the geological process fatigue damage can occur, and with fracture, and then cause structure generation Progressive Collapse when serious, jeopardize personnel's life.Even if structure does not collapse, it is very high to repair replacement cost after its shake, also can affect the normal usage function of building, brings huge negative effect can for the production of society, life.
Adopting the energy-dissipating and shock-absorbing technology is the new developing direction of design of building structures; this design concept is by being the additional energy-dissipating device dissipation inputting seismic energy of structure; protect main structure body not to be subjected in the earthquake centre or few damaged, can also be convenient for changing after the shake, do not affected the use function of structure.Simultaneously, energy-consumption shock-absorption device can also provide larger additional damping for structure, thus reduction the response spectrum of geological process, reduced the seismic forces of structure, make the building that need to carry out seismic design more economical, cost is lower.
This method for designing has many clear superiorities, but realizes that the basis of this design concept is, can provide anti-seismic performance good energy-consumption shock-absorption device.Energy-consuming shock absorber commonly used has viscous damper, viscoelastic damper, metal damper etc.Existing shearing-type metal damper mainly contains two kinds, and namely consume energy by the steel plate bending that the middle part that utilizes a series of parallel connections weakens (1); (2) by for shearing steel plate solder side adding rib, be a plurality of residential quarters lattice with steel plate partition, to prevent the outer flexing of steel plate surface, carry out shear energy dissipation.At present, also there is a problem in existing shearing type damper, namely is out of shape and can not recovers after its surrender power consumption work, has larger permanent set, will affect structure normal usage function and reparation.
Summary of the invention
The utility model is intended to overcome the defective of prior art, and a kind of Self-resetting metal sheet slitting damper is provided.The utility model adopts prestressed cable, and the permanent set after the energy-dissipating device yield deformation is recovered, thereby improves and reduced permanent set after the shearing type damper earthquake.
In order to solve the problems of the technologies described above, the utility model is achieved in that a kind of Self-resetting metal sheet slitting damper, and it comprises:
The square frame that the upper lower connecting plate in strap bolt hole and left and right sides junction plate consist of;
A Wasted-energy steel plate that is arranged in the described square frame, its up and down both sides respectively the same lower connecting plate are welded and fixed;
The a pair of up and down channel-section steel on both sides of Wasted-energy steel plate that is arranged on, channel-section steel two ends and left and right sides junction plate are welded to connect, and the channel-section steel inboard is near Wasted-energy steel plate;
Two high-strength prestressed cable wires, they are the diagonal cross setting in square frame, and the outer wall that is anchored at the left and right sides junction plate behind the left and right connecting plates is passed at two ends separately.
Described a kind of Self-resetting metal sheet slitting damper, described Wasted-energy steel plate is formed by a steel plate both sides waist weakening.
Described a kind of Self-resetting metal sheet slitting damper, described Wasted-energy steel plate and channel-section steel are equipped with stiffening rib.
Described a kind of Self-resetting metal sheet slitting damper, described Self-resetting metal sheet slitting damper is arranged on the building beam.
The utility model utilizes shear yielding power consumption in the steel plate surface, but does not weld stiffening rib at Wasted-energy steel plate, is undertaken outside the Wasted-energy steel plate face buckling-restrained by two-sided channel-section steel.This be because, be in fact on the power consumption material, to have caused artificially weld defect at steel plate welding stiffening rib, welding residual stress can have a strong impact on the low cycle fatigue property of metal damper, it is destroyed ahead of time occur, and can not take full advantage of its energy dissipation capacity.
The utility model can greatly improve the ability of building structure opposing horizontal earthquake action, improve the anti-seismic performance of structure, yield strength by changing Wasted-energy steel plate, width, highly, thickness, etc. parameter, yield displacement and the yield force of this damper can be adjusted easily, the multiple demand of different building structure can be satisfied; And overcome the shortcoming that permanent set is arranged after existing shearing-type metal damper plasticity consumes energy, reduce the permanent set of structure, thereby alleviated earthquake.
