Preferentially, the U-shaped mild steel plate of damper core is divided into two rows, is individually fixed in rectangular guide bar and protecting crust
On.
Preferably, the damper is the non-longitudinal displacement that guide rod is constrained by protecting crust.
Preferably, using welding between the damper rectangular guide bar and U-shaped mild steel plate, protecting crust and U-shaped mild steel plate
It is fixedly connected with fixing piece.
Preferably, damper extreme displacement protection board is set to sliding guide both ends, occurs for working as structure beyond damping
During large deformation except device normal operation stroke range, it is ensured that damper remains to normal operation without because being led by unexpected destruction
It causes to lose the earthquake resistant control protective effect to structure.
Preferably, the cross section of the fixing piece of the U-shaped mild steel plate of damper fixation is designed as specific arc-shaped.
The working principle of design of the present invention：
The main body of the Novel U-shaped mild steel damper is by U-shaped mild steel plate, spring, sliding guide, rectangular guide bar, protecting crust structure
Into, and the non-longitudinal displacement of rectangular guide bar is constrained by protecting crust, and the damper is connected to structure energy-eliminating shock-absorbing by connector
In system, in damper working condition, pull sliding guide that can drive the deformation of U-shaped mild steel plate, increase additional damping, realize
The purpose of structure energy-eliminating shock-absorbing.
The device have the advantages that it is：
The present invention provides a kind of U-shaped mild steel energy dissipation dampers of spacing collar, add protecting crust in the damper, keep away
Exempt from U-shaped mild steel damper and buckling unstability occurs outside face；The fixing piece of fixed U-shaped mild steel plate, cross section is designed as specific circle
Arc, the fixing piece of the form, which can prevent from fixing, there is serious stress concentration phenomenon at U-shaped mild steel plate；The U-shaped mild steel of the construction
The main body of damper is made of U-shaped mild steel plate, spring, sliding guide, rectangular guide bar, protecting crust；And at sliding guide both ends
Extreme displacement protection board is set, prevents excessive deformation from causing the unexpected destruction of damper.The energy dissipation damper simple structure, cost
It is cheap, it is easy to produce in batches, can be applied in various structure energy-eliminating shock-absorbing systems.
