Position hole 18, two spacing holes 18 arrange in the axis direction of outer barrel 10, and the diameter parallel of spacing hole 18 is in the axis of outer barrel 10, and two
The second chain 6 of section is each passed through a spacing hole of two pieces of limiting plates 12.
Embodiment three
For the present embodiment unlike embodiment one, this specific embodiment substitutes stretch-draw prestressing force rod iron, rubber blanket with steel strand wires
37 between the 3rd junction steel plate 31 and the 4th junction steel plate 32, and described rubber blanket 37 is made up of two layers of rubber blanket, two layers
Rubber blanket is fixed between the 3rd junction steel plate 31 and the 4th junction steel plate 32 by fixing device, the first steel cylinder 42 and the second steel
Cylinder 43 is in two layers of rubber blanket respectively, and other structures are identical.
Slip limit guide rail 13 in previous embodiment can be the retainer that multilayer is provided with ball or roller, retainer
It is fixed on outer barrel 10, the second chain 6 passes through from the centre of two layers of ball or roller.
The operation principle of assembled abnormity Column border node of the present invention：Assembled abnormity Column border node of the present invention includes node power consumption dress
Put and be arranged on the junction of Special-Shaped Column 1 and crossbeam 2 with spacing energy-dissipating device, node energy-dissipating device, spacing energy-dissipating device is arranged on
Special-Shaped Column 1 and 2 at least one angle of crossbeam；When earthquake occurs, the node of Special-Shaped Column 1 and crossbeam 2 is caused crossbeam by shearing force
1 is vertically subjected to displacement, and power consumption post 39 slides up and down in power consumption hole 41, absorbs the shearing force at bean column node, reduces crossbeam 2
Displacement, while elastic deformation occurs for the 4th junction steel plate 32 extruding rubber blanket 37, rubber blanket 37, absorbs the energy of consumption earthquake release
Amount；When earthquake occurs, when the angle between Special-Shaped Column 1 and crossbeam 2 becomes big, torsion spring 20 is stretched, and drive chain 4 is elongated, fixed pulley
14 promote drive chain 4 to rotate, and the first chain 5 of drive chain 4 and the connection end of the second chain 6 reach constantly close to limiting plate 12
During limiting plate 12, because the first chain 5 can not just be held limiting plate 12, driven by limiting plate 12 by spacing hole 18, drive chain 4
Dynamic outer barrel 10 rotates, and because inner cylinder 11 is fixed in Special-Shaped Column 1 by the second junction steel plate 7, is sent out between outer barrel 10 and inner cylinder 11
Raw to relatively rotate, the power consumption piece 9 between outer barrel 10 and inner cylinder 11 is broken, therefore the piece 9 that consumes energy absorbs the energy of consumption earthquake release,
When the rotation amplitude of outer barrel 10 is larger, the first junction steel plate 8 and the second junction steel plate 7 deform, or even fracture, further inhale
Receive the energy of consumption earthquake release.After earthquake terminates, rubber blanket 37 recovers original state, promote crossbeam 2 return to it is original from
Right shape, damaged spacing energy-dissipating device can be dismantled in junction, and install new spacing energy-dissipating device.Node energy-dissipating device and limit
The collective effect of position energy-dissipating device, it can ensure that the beam and column of this assembled abnormity Column border node is not broken in big rank earthquake by larger
It is bad.
