Background technique

Setting displacement dampers in building structures is one of the main means of energy dissipation and shock absorption technology. Mild steel dampers and buckling restraint braces are the two most common displacement dampers at present. Mild steel dampers usually use low-yield steel, which can better realize energy dissipation under frequent earthquakes, but to effectively realize energy dissipation under large earthquakes, the steel must have high ductility at the same time, which is suitable for soft The design and production of steel dampers pose higher requirements and challenges. Buckling-restrained bracing can better realize energy dissipation under moderate and large earthquakes, but it usually does not play an energy-dissipating role under small earthquakes. How to realize the effective energy dissipation of energy-dissipating shock-absorbing devices under different seismic performance levels is one of the problems to be solved in engineering shock-absorbing technology at the present stage.

The purpose of this utility model is to aim at the deficiencies of the prior art and design a damping and restraint support combined shock absorbing energy-consuming device, which adopts a shock absorbing structure combining buckling restraint and damping, once the earthquake and wind load reach or exceed the limit of the damper If the limit of energy dissipation and shock absorption is reached, the buckling restraint support will continue to play the role of energy dissipation and shock absorption, realizing the effective energy consumption of the building structure under different seismic performance levels, ensuring building safety, simple structure, convenient installation, and a better solution to energy consumption. The issue of effective energy dissipation of shock absorbers at different levels of seismic performance.

The purpose of this utility model is achieved in the following way: a damping energy-consuming device combined with damping and restraint support, including a mild steel damper and a buckling restraint support, which is characterized in that the mild steel damper and buckling restraint support are respectively fixed on the connecting The upper part and the lower part of the plate, the mild steel damper buckles the box body with limit baffles on both sides, the mild steel damper and the box body are in sliding connection, the lower end of the limit baffle is provided with a collision buffer body, and the collision buffer The body and the limit baffle are fixedly connected; the connecting plate is arranged between the two limit baffles and is in clearance fit with the two collision buffer bodies; the buckling constraint supports are two and are fixedly arranged with an equilateral triangular support structure at the bottom of the connecting plate.
