The present embodiment is what is different from the first embodiment is that this specific embodiment substitutes stretch-draw prestressing force rod iron, rubber pad with steel strand wires
Between third junction steel plate 31 and the 4th junction steel plate 32, the rubber pad 37 is made of two layers of rubber pad, two layers of rubber
Rubber mat is fixed between third junction steel plate 31 and the 4th junction steel plate 32 by fixed device, the first steel cylinder 42 and the second steel cylinder
43 are in respectively in two layers of rubber pad, and other structures are identical.
Sliding 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 cylinder 10, the second chain 6 is passed through from the centre of two layers of ball or roller.
The working principle of assembled abnormity Column border node of the present invention: assembled abnormity Column border node of the present invention includes node energy consumption dress
Energy-consuming device is set and limits, the junction of Special-Shaped Column 1 Yu crossbeam 2 is arranged in node energy-consuming device, and limit energy-consuming device setting exists
Special-Shaped Column 1 and at least one angle of crossbeam 2；When earthquake occurs, the node of Special-Shaped Column 1 and crossbeam 2 is led to crossbeam by shearing force
1 is vertically subjected to displacement, and energy consumption column 39 slides up and down in energy consumption hole 41, absorbs the shearing force at bean column node, reduces crossbeam 2
Displacement, while the 4th junction steel plate 32 squeezes rubber pad 37, flexible deformation occurs for rubber pad 37, absorbs the energy of consumption earthquake release
Amount；When earthquake occurs, when the angle between Special-Shaped Column 1 and crossbeam 2 becomes larger, torsional 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 connecting pin of the second chain 6 reach constantly close to limit plate 12
When limit plate 12, since the first chain 5 cannot just be held limit plate 12, be driven by limit plate 12 by limit hole 18, drive chain 4
Dynamic outer cylinder 10 rotates, and since inner cylinder 11 is fixed in Special-Shaped Column 1 by the second junction steel plate 7, sends out between outer cylinder 10 and inner cylinder 11
Raw to relatively rotate, the energy consumption piece 9 between outer cylinder 10 and inner cylinder 11 is broken, therefore the piece 9 that consumes energy absorbs the energy of consumption earthquake release,
When 10 rotation amplitude of outer cylinder 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, rubber pad 37 restores original state, promote crossbeam 2 be restored to it is original from
Right shape, damaged limit energy-consuming device can be dismantled in junction, and install new limit energy-consuming device.Node energy-consuming device and limit
The collective effect of position energy-consuming device 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.
