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 that steel plate and auxiliary stopper part are limited 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 operate normally stroke beyond damper when structure
When large deformation except range, it is ensured that damper remains to operate normally without because causing to lose to structure by unexpected destruction
Earthquake resistant control protective effect.
Preferably, the cross section of the fixing piece of the fixed U-shaped mild steel plate of the damper is designed as specific arc-shaped.
Working principle of design of the 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 are as follows:
The present invention provides a kind of novel U-shaped mild steel energy dissipation dampers, joined rectangle limit steel 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 be designed as it is specific arc-shaped, the fixing piece of the form can prevent from fixing at U-shaped mild steel plate occur serious stress concentrate it is 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
Support, energy dissipating node have wide range of applications in connecting with energy dissipating.
