Due on sliding guide and connecting rod.In damper work, for the stress collection for avoiding bearing to occur to a certain extent
Middle phenomenon, fixing piece cross section are designed as arc-shaped.
Preferentially, the damper is U-shaped mild steel metal damper.
Preferentially, the U-shaped mild steel plate of damper core is divided into two rows, be individually fixed in rectangular slide guide rod and up and down
In connecting rod.
Preferably, the damper is to limit steel plate and auxiliary stopper part by rectangle to constrain sliding guide and connect up and down
The lateral displacement of extension bar.
Preferably, by solid between the damper sliding guide and U-shaped mild steel plate, between connecting rod and U-shaped mild steel plate
Determine part to be fixedly connected, U-shaped mild steel plate end is using welding.
Preferably, extreme displacement protection board is arranged in damper, for occurring to exceed damper normal operation stroke when structure
When large deformation except range, it is ensured that damper remains to normal operation without because causing to lose to structure by unexpected destruction
Earthquake resistant control protective effect.
Preferably, the damper fix the fixing piece of U-shaped mild steel plate cross section be designed as it is specific arc-shaped.
The working principle of design of the present invention：
The main body of the Novel U-shaped mild steel damper by sliding guide, be vertically connected with bar and connect U-shaped mild steel plate and constituted, and
The laterally opposed displacement of sliding guide and connecting rod is constrained by rectangle limit steel plate, and the damper is connected to by screw hole
In structure energy-eliminating shock-absorbing system, in damper working condition, pull sliding guide or connecting rod that can drive the change of U-shaped mild steel plate
Shape increases additional damping, realizes the purpose of structure energy-eliminating shock-absorbing.
The device have the advantages that being：
The present invention provides a kind of novel U-shaped mild steel energy dissipation dampers, and rectangle limit steel is added in the damper
Plate and auxiliary stopper part, avoid U-shaped mild steel damper that buckling unstability occurs outside face；The fixing piece of fixed U-shaped mild steel plate, it is horizontal
Section is designed as specific arc-shaped, and the fixing piece of the form can prevent from fixing that occur serious stress concentration at U-shaped mild steel plate existing
As；The main body of the U-shaped mild steel damper of the construction by sliding guide, be vertically connected with bar and connect U-shaped mild steel plate and constituted；And it is sliding
Extreme displacement protection board is set on guide rod, prevents excessive deformation from causing the unexpected destruction of damper；Suitable for building structure energy dissipating
During support, energy dissipating node are connected with energy dissipating, have wide range of applications.
