Description
Technical field
The present invention relates to a kind of device of amplifying energy consumption effect of damper, imitated more particularly, to one kind amplification damper power consumption
The scissor deformation amplifying device of fruit.
Background technology
Energy-dissipating and shock-absorbing technology is one of more ripe new and high technology of current world's earthquake engineering circle popularization and application, beautiful
State seismological expert is referred to as " one of 40 most important achievements of Nian Lai worlds earthquake engineering ".
Damper is widely used in building structure and bridge as energy-dissipating and shock-absorbing product, to ensure people's life and wealth
Production safety is made that significant contribution.But, because damper can only play good energy consumption effect under larger displacement,
And used at present damper in the structures such as the less shear wall of displacement, frame cylinder, it is impossible to gratifying effect is obtained, seriously. more
Constrain the application of damper in these structures.
The A of Chinese patent CN 102587532 disclose a kind of device of amplifying energy consumption effect of damper, including structural column,
Beam, connecting plate, head rod, the second connecting rod and damper, the structural column housing for connecting and composing device vertical with beam, housing
Three apexes be respectively equipped with connecting plate, wherein one end of head rod, the second connecting rod and damper is connected to a bit,
The other end is connected to three connecting plates.Head rod and the second connecting rod are not point-blank.Damper, first connect
The connected mode of extension bar and the second connecting rod is to be hinged.The connection of head rod, the second connecting rod and damper and connecting plate
Mode is to be hinged.The device, which has, can effectively amplify displacement and speed of the damper under strong wind or geological process, improve
The advantages of energy consumption effect of damper, but the device more takes space.
At present, known scissor deformation amplifying device is made up of damper, support, attachment means.In frame plane,
Damper one end is hinged with support 1, support 3, and the damper other end is hinged with support 2, support 4；Support 1, support 2 are articulated with
The somewhere of portion's Vierendeel girder, support 3, support 4 are articulated with the bean column node of lower frame one.Under geological process and wind load, structure
Effect takes place in generation relative storey displacement, deformation amplifying device, and damper two ends produce the relative displacement more than relative storey displacement, plus
The power consumption of big damper, improves the additional damping ratio of wind load and Structures under Earthquake, lifts integrally-built security.But
Due to no using unstability outside the anti-locking apparatus plane of special construction measure, under rarely occurred earthquake effect, malformation is larger, can
Damping force can be caused excessive, the outer unstability of plane occurs for device, damper two ends do not reach expected relative displacement, damper power consumption
It is relatively expected small, cause structure not reach the performance objective of design, the heavy damage under rarely occurred earthquake effect.
The content of the invention
The purpose of the present invention is exactly the defect in order to overcome above-mentioned prior art presence and provides a kind of amplification damper consumption
Can effect scissor deformation amplifying device, what apparatus of the present invention can amplify damper is displaced to more than 2 times of relative storey displacement, plus
The power consumption of big damper, improves the additional damping ratio of wind load and Structures under Earthquake；And use the anti-locking apparatus of construction measure
The unstability outside rarely occurred earthquake effect lower plane, ensures security of the structure under rarely occurred earthquake effect.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of scissor deformation amplifying device of amplifying energy consumption effect of damper, the device is arranged on by the structure of left and right two
In post and the up and down framework of two beams compositions, the device is supported and the 4th including damper, the first support, the second support, the 3rd
Support, the first described support is hinged on one end of damper, described the second support and the 4th support with the 3rd support simultaneously
