Abstract
The utility model relates to an energy-dissipating and shock-absorbing damper, which has the characteristics of high stiffness, strong deformability and strong energy dissipation capacity, and has the advantages of having clear load carrying capacity, adopting a simple structure, being convenient to produce, needing low price, being easy to install and maintain, and having good durability. The energy-dissipating and shock-absorbing damper can be applied to a building with a multistory or high-rise concrete structure and a steel structure, and is connected with the main body of a building structure through bolt connection or welding to form an energy-dissipating and shock-absorbing structure system; the damper not only can play a role of dissipating energy and absorbing shock under the action of strong shock, but also can play a role of dissipating energy under the action of weak shock; and the safety of the building is ensured.
Description
Affiliated technical field
The utility model belongs to building and civil engineering structures anti-seismic technology field, relates to a kind of novel energy-dissipation shock-absorbing damp.
Background technology
Earthquake is the human the most serious sudden natural calamity that is faced, and China is as the economics of underdevelopment country of an earthquake pilosity, and taking economy, effective measures to improve the shock resistance of having built and planned to build building is problem demanding prompt solution.Geological process is equivalent to the input of energy, and therefore the works under severe earthquake action should have enough energy dissipation capacities, can avoid destroying.Traditional Aseismic Structure System is by the damage consumed energy of structure and supporting member, cause structural element damage in various degree to occur even collapse, this be unreasonable also be unsafe.Structure energy-dissipating and shock-absorbing technology is a kind of antidetonation prevention technique of new active, in the structural system that adopts the energy-dissipating and shock-absorbing technology, some nonload bearing element of structure is designed to have the particular components-damper of big energy dissipation capacity, during little shake, structure itself has enough lateral rigidities to satisfy instructions for use, and structure is in elastic stage; During big the shake, along with the increase of structure lateral deformation, the damper rate is introduced into inelastic state, produces big damping, the seismic energy of concentrated area dissipative structure, and the vibration of attenuating structure is reacted rapidly, thereby avoids or reduce the damage of agent structure.
Developed multiple dissipative cell at present both at home and abroad, wherein mild steel class damper is widely promoted practicality with its economic, practical property at building circle.Mild steel class damper mainly is by providing good plastic strain to realize energy-dissipating property after the steel surrender, still having stable hysteretic characteristic under the cyclic loading effect repeatedly, good low-Cycle Fatigue Characteristics after the surrender.
But the damper of development generally only plays a role under severe earthquake action both at home and abroad at present, more is the rigidity that relies on building structure itself to have under the little shake effect.
Summary of the invention
The purpose of this utility model provides a kind of novel energy-dissipation shock-absorbing damp, and not only damper can be brought into play the energy-dissipating and shock-absorbing effect under severe earthquake action, equally also can bring into play the power consumption effect under little shake effect, guarantees the safety of building.
The technical scheme that its technical problem that solves the utility model adopts is: the earthquake-damping damper is made up of several sections such as pressing plate, clamping plate, energy dissipating sheet, rubber packing materials, and pressing plate, clamping plate, energy dissipating sheet all adopt the Q235 steel.Clamping plate adopt 14 isometric steel plates of uniform thickness to be formed by stacking, and are symmetrical up and down, and the steel plate that has 3 hollow rhombus holes in the middle of the energy dissipating sheet adopts is formed, 6 altogether of energy dissipating sheets; Clamping plate and energy dissipating sheet are superimposed mutually, are connected by bolt with pressing plate.
Filled rubber vibration-absorptive material in the damper plays the bumper and absorbing shock effect.Under little shake effect, energy dissipating sheet and rubber play the power consumption effect jointly like this.
To have rigidity big for the energy-dissipation shock-absorbing damp of Zu Chenging thus, the characteristics that deformability is strong, energy dissipation capacity is strong, and it is stressed clear and definite, and simple structure is easily manufactured, cheap, be easy to installation and maintenance, good endurance.Not only performance energy-dissipating and shock-absorbing effect under severe earthquake action equally also can be brought into play the power consumption effect under little shake effect.
During concrete engineering design, can adjust quantity, width, thickness and the length of steel plate, select different rubber models, can design damper with different initial stiffnesses and energy dissipation capacity.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing 2 is energy-dissipation shock-absorbing damp exterior sideview views of the present utility model.
Accompanying drawing 3 is not for there being the damper lateral plan before the filled rubber vibration-absorptive material.
Accompanying drawing 4 is energy dissipating sheet (3) schematic diagram.
The specific embodiment is:
As shown in Figure 1, energy-dissipation shock-absorbing damp of the present utility model is by superimposed successively composition of energy dissipating sheet (3) of the clamping plate (2) of 14 equal thickness, equal length and 6 equal thickness, equal length, each 7 up and down on clamping plate, symmetrical up and down, connect by screw rod bolt (4), clamping plate (2) and energy dissipating sheet (3) are clamped with pressing plate (1).Filled rubber vibration-absorptive material (5) in the damper.
