Control field.
Background technology：
Anti-buckling support is in the outside compressive buckling for setting sleeve pipe constraint support of support, to solve common support by lateral deflection
The problem of bent and Hysteresis Behavior difference, is a metalloid surrender type damper.Anti-buckling support has advantages below：(1) its from
The bearing capacity of body is separated with rigidity, and requirement of the structure for bearing capacity can be met on the premise of the rigidity of structure is not increased；(2) hold
Carry power high；(3) ductility is good with Hysteresis Behavior；(4) can be used to protect agent structure；(5) support tension and compression bearing difference
It is small, adjacent members stress can be reduced.The application of anti-buckling support, improves antidetonation of the traditional support framework under middle shake and big shake
Performance.
Where all being undertaken by the core plate being connected with other components suffered by traditional anti-buckling support, outer sleeve and
Packing material is provided solely for constraining the effect of core plate compressive buckling, is bent with ensureing that core plate can enter in the case where tension and compression are acted on
Clothes, have the shortcomings that power consumption form is single.
The content of the invention：
To improve the energy dissipation capacity of traditional anti-buckling support, the invention provides a kind of anti-buckling branch of friction energy-dissipating formula
Support.
To achieve the above object, design of the invention is as follows.A kind of anti-buckling support of friction energy-dissipating formula, includes about
Beam component 1, piston 2, power consumption core 3；The middle part of power consumption core 3 sets piston 2, and confining part 1 is enclosed within the surface of piston 2；Constraint
Component 1 is fixed by end plate 4 with power consumption core 3 one end；Junction steel plate 5 is provided with the two ends of power consumption core 3.
The described section form of confining part 1 is square, rectangle or circle.
The quantity of described piston 2 is one or more, and the section form of piston 2 is surrounded with the section of confining part 1
Portion-form is consistent.
Described power consumption core 3 is the in-line or cross steel plate that middle part weakens.
When structure occurs relative storey displacement, power consumption core produces plastic deformation consumed energy, while consume energy core and constraint
There is relative displacement in component, the piston being fixed on power consumption core occurs relative motion with confining part, by piston and constraint
The friction consumed energy of component.
The present invention sets piston in traditional anti-buckling support, introduces friction energy-dissipating mechanism, effectively increases anti-buckling branch
The energy dissipation capacity of support.
