Description

A kind of metal damper that is provided with restraint device, stiffening rib
Technical field
The present invention relates to building engineering structure anti-seismic technology field, specifically, relate to a kind of building energy dissipating metal damper that is provided with restraint device, stiffening rib.
Background technology
The energy-dissipating and shock-absorbing of building structure is meant suitable energy dissipation component is set that energy dissipation component can be made up of supporting members such as energy-consumption shock-absorption device and diagonal brace, body of wall, beam or nodes in building structure.The metal energy consumer is that a kind of energy-dissipating property is superior, simple structure, easy to make, cheap, the energy-consumption shock-absorption device that is easy to change.It both can cooperate shock isolating pedestal or shock isolation system, as power consumption unit or stopping means wherein, can be used for building structure separately as energy-dissipating device again, and additional damping and rigidity are provided, and therefore was with a wide range of applications.
Because metal has good hysteretic characteristic after getting into plastic state, and in elastoplasticity hysteresis deformation process, absorbs significant amount of energy, thereby be widely used for making energy dissipative device dissimilar and structure.Chinese scholars, engineers and technicians have successively developed polytype metal energy consumer, at present main use X type, triangle and perforate shape adding damping and stiffness device arranged.This metalloid energy consumer has energy-dissipating property preferably, however because what adopt is the stress form plane outside, and initial stiffness is less, when required tonnage weight greatly time the, length also corresponding bigger.
To this, can adopt that the metal damper of stress form overcomes above-mentioned shortcoming in the plane.But the power consumption steel plate of stressed metal damper is prone to flexing outside the plane takes place in the plane, causes energy dissipation capacity decline, the unstable properties of damper.
Summary of the invention
The object of the invention is to overcome existing technical deficiency, has proposed a kind of metal damper that is provided with restraint device, stiffening rib, has overcome in the existing steel plate plane to be prone to take place outside flexing and the steel plate plane the lower defective of initial stiffness when stressed when shearing.
The present invention realizes through following technical scheme:
A kind of metal damper that is provided with restraint device, stiffening rib; The level that comprise the power consumption steel plate, is arranged on power consumption steel plate upper and lower connects steel plate, be arranged on the frange plate at power consumption steel plate two ends, be arranged on the stiffening rib and the restraint device of power consumption steel plate both sides; Said power consumption steel plate and up and down level connect between the steel plate through being welded to connect; The frange plate at said power consumption steel plate and two ends adopts and is welded to connect; The both sides of said power consumption steel plate are respectively equipped with restraint device, and this restraint device is provided with bolt hole, and the restraint device of said power consumption steel plate both sides connects fixing through bolt.
Further, said restraint device and said power consumption steel plate are separate.
Further, said restraint device level is arranged in the both sides of power consumption steel plate in pairs and does not intersect.
Further, said stiffening rib branch level and vertical both direction are elongated is arranged in the both sides of said power consumption steel plate and does not intersect.
Further, said stiffening rib branch level is arranged in the both sides of said power consumption steel plate with vertical both direction part and does not intersect.
Further, the direction of the local stiffening rib of said power consumption steel plate one side can be identical or different.
Further, said power consumption steel plate is a rectangle or square.
Further, said power consumption steel plate is provided with hollow out or does not establish.
Further, said hollow out shape can adopt circle, ellipse, rectangle, rhombus or bar shaped.
Further, said power consumption surface of steel plate sticks silica gel plate or rubber tile, is filled between the head and power consumption steel plate of anti-flexion device.
Further, be provided with the soft glass of antifriction usefulness between the frange plate at the bottom of restraint device and two ends.
Structural principle of the present invention: the power consumption steel plate is the power consumption parts of damper; And the initial stiffness of metal damper is provided, stiffening rib, the restraint device of said power consumption steel plate both sides can retrain the power consumption steel plate; Prevent that it from flexing outside the plane taking place; It is the fixed connection apparatus of metal damper that said level up and down connects steel plate, guarantees power consumption steel plate upper and lower side generation relative deformation, and links to each other with other building structure; The frange plate at power consumption steel plate two ends, the cripling phenomenon takes place and guarantees in stable hysteresis performance of large deformation stage in the steel plate that prevented to consume energy before surrender.
The present invention has the following advantages:
1, utilizes in the power consumption steel plate plane the bigger advantage of initial stiffness when stressed, and the flexing outside the plane of steel plate that prevents to consume energy of the mode through constraint, guaranteed the energy dissipation capacity and the stability of damper;
2, do not have the weld seam of intersection between the stiffening rib of power consumption steel plate homonymy, stiffening rib can elongated setting and need not to block, convenient welding, and welding quality guarantees easily.
3, restraint device is independent of the power consumption steel plate, avoided the power consumption steel plate on the welding put more energy into to the power consumption steel plate itself cause damage.
