Abstract

The utility model relates to a mild steel energy-dissipation vibration damper which has the characteristics of large rigidity, strong deformation capability and energy consumption capability, as well as the advantages of clear carrying capability, simple structure, convenient manufacturing, low price, easy installation and maintenance and good durability. The novel energy-dissipation vibration damper can be used in buildings with multilayered and high-rise concrete structures and steel structures, is connected with a building structure main body by adopting a bolt or welding so as to form an energy-dissipation vibration damping system, thus solving the safety problem of the structure under the action of rarely occurred earthquake.

Description

Novel energy-dissipation shock-absorbing damp
Affiliated technical field
The utility model belongs to building and civil engineering structures anti-seismic technology field, relates to a kind of novel mild steel 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.
Present known metal damper as triangle, X-shaped, circular arc, two annular, square frame shape mild steel damper, all is to come earthquake energy by plastic deformation of metal material.These metal dampers are because planform is single, and its initial stiffness is not high, and yield deformation is less than normal, and energy-dissipating property is undesirable, and when the energy-dissipating and shock-absorbing design of carrying out building structure aseismatic, rigidity, yield deformation and the energy dissipation capacity of existing metal damper can not be taken into account.Initial stiffness is too little, can not satisfy the normal use under the situation of little shake; Yield deformation and energy dissipation capacity are poor, under shake and the big earthquake situations condition enough energy dissipation capacities are arranged in can not guaranteeing.
Summary of the invention
The purpose of this utility model provides a kind of novel mild steel energy-dissipation shock-absorbing damp, increased substantially the initial stiffness of mild steel class damper, also can guarantee simultaneously the energy-dissipating property after steel are surrendered, can realize the antidetonation thought of dissipation seismic energy under the big shake effect, have good economic benefit.
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 sheets, 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 each 7 up and down, symmetrical up and down, 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.
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.
During concrete engineering design, quantity, width, thickness and the length of steel plate can be adjusted, damper can be designed with different initial stiffnesses and energy dissipation capacity.
