Description
Technical field
The utility model belongs to structural seismic field, especially for the antidetonation of complex high-rise building, is specifically related to a kind of damper amplifying device.
Background technology
Earthquake is a kind of natural phenomena, is that the vibration caused in curstal fault transient burst of energy process produces seismic wave simultaneously.China is the country of earthquake more than, the earthquake of earthquake magnitude more than 7 grades nearly nearly 100 times more than, the destructive power of earthquake is strong, and economy, the suffering heavy losses of personnel, become the research direction of world's field of civil engineering about earthquake research.The mode of damper is installed at tradition diagonal angle, and due under geological process, structure relative storey displacement is very little, causes the relative displacement of damper two ends very little, cannot give full play to the cushioning effect of damper.
Utility model content
The technical problems to be solved in the utility model: provide a kind of damper amplifying device, adopts traditional diagonal angle to install the mode of damper to solve prior art, cannot give full play to the problem of damper damping effect.
Technical solutions of the utility model:
A kind of damper amplifying device, it comprises damper, the first rigid support and the second rigid support hinged formation elbow braced structures, and damper is hinged on the summit of elbow support and the node of Structure Beam-column.
First rigid support and the second rigid support are steel pipe.
The angle theta on the first rigid support and ground
1be less than or equal to the diagonal of framework and the angle theta of beam, the length L of the first rigid support
1<L/cos θ
1, the length of the second rigid support is L
2.
The beneficial effects of the utility model:
The utility model adopts the rigid support of elbow shape, and namely its rigidity numerical value thought that the rigidity of rigid support is approximate and recognized infinity between being 1000 times to 10000 times of damped coefficient.By the displacement geometry amplification of elbow system, promote the damping force of damper, displacement equations multiple is 2-6 times, by this damper amplifying device, by the geometrical relationship that elbow supports, amplify the relative displacement at damper two ends when relative storey displacement is very little, reach the object of the damping effect giving full play to damper with this, solving prior art adopts traditional diagonal angle to install the mode of damper, cannot give full play to the problem of damper damping effect.
