2, the nodal connection device of this patent is a kind of nodal connection device of recoverable function after shake, and the edge of a wing uses single-blade
Edge cover board type of attachment, by Reasonable Parameters design so that plastic failure occurs in splice region, and cantilever beam section and I-shaped beam section
Basic to keep elasticity, only need to replace attachment device can restore the use function of main structure after shake.Pass through square steel tube in reinforcing
The wall thickness of column and increase side's shape annular partition thickness, to realize effective reinforcement to Column border node domain and cantilever beam section；By to the wing
Edge cover board setting circular arc dog bone weakens area or the shearing that punches weakens area and reaches plastic hinge to realize effective weakening of bonding pad
The purpose of outer shifting.
3, attachment device of the invention is Self-resetting attachment device, can realize self-resetting, reduction remnants after structure shake
It deforms, structure main bearing member is delayed to damage process, guarantee the predetermined condition design object of structure dissipation seismic energy and drop
Rehabilitation cost after low shake is the new direction of steel construction development.
4, automatic runback device is connected with prestress wire by two toolings and is formed, what cover board and prestress wire were formed
Automatic runback device is compared with traditional drag-line automatic runback device, in the identical situation of prestress wire pretension, using runback
The total bearing capacity of the beam of position device can be higher；In the identical situation of bearing capacity of beam, the prestress steel twist of automatic runback device
Line pretension demand can reduce, and avoid prestress wire pretension to the overstressing load of I-shaped beam section；It is pre- by applying
Prestress steel strand pretension, the accumulation of the development and damage that are plastically deformed structure control make structure have good shock resistance
Energy and reset capability.
