Embodiment
Specific embodiment of the utility model is described further below in conjunction with the accompanying drawings.
As shown in Fig. 1 to Figure 14, a kind of stiffness variable buckling restrained brace of leaded core material, including core plate 1, ribbed stiffener
2nd, put more energy into floor 3, packing material 4, band groove steel plate 5, external constraint component 6, lead for retractable pencil material 7, jacking apparatus, the core plate 1
Periphery sets external constraint component 6, and packing material 4, packing material 4 and core plate 1 are set between core plate 1 and external constraint component 6
Between apply whether there is binding material so that without cohering between packing material and core plate.Both sides set ribbed stiffener up and down at the both ends of core plate 1
2, floor 3 of putting more energy into is fixed on the top of ribbed stiffener 2, and the band groove steel plate 5 is fixed on inside external constraint component 6, and its position is with adding
The position of strength floor 3 is corresponding, and described put more energy into and is in close contact floor 3 with groove steel plate 5, the upper surface for floor 3 of putting more energy into
And the lower surface with groove steel plate 5 is provided with the groove that position is completely superposed, and places lead for retractable pencil material 7 between two pieces of steel plate grooves, adds
Strength floor 3, band groove steel plate 5 and the perforate at same position of external constraint component 6, one end of jacking apparatus are placed in perforate
In, the other end is placed on core plate 1.
As shown in Fig. 5 to Fig. 8, the jacking apparatus includes pulley groove 8, pulley 9, connecting rod 10, cylinder 11, the pulley groove
8 are fixed on the surface of core plate 1, and the pulley 9 is placed in pulley groove 8, can along slide, the pulley 9 by connecting rod 10 with
Cylinder 11 connects, and cylinder 11 is placed in floor 3 of putting more energy into, the perforate with groove steel plate 5 and external constraint component 6 at same position
In.
The external constraint component 6 is square steel tube or round steel pipe.The core plate 1 is using low surrender steel core plate.
Principle of the present utility model is as follows：
In the case of normal operating condition and frequently occurred earthquake, by the connection of jacking apparatus middle column body by core plate, ribbed stiffener,
Put more energy into floor and external constraint component forms an entirety, common stress, and the axial rigidity of external constraint component also serves as flexing
A part for constraint support integral rigidity, the axial rigidity of buckling restrained brace external constraint component can be rationally utilized, is improved
The overall axial rigidity of buckling restrained brace, and then improve structure anti-side rigidity.
In the case of middle shake and rarely occurred earthquake, core plate back and forth draws high stroke increase, and pulley groove propelling sheave is obliquely therewith
Motion, height of pulley increase, the overall motion upwards of jacking apparatus therewith, after reaching setting height, jacking apparatus is sent out because of gravity
Life come off, cylinder no longer contacts with floor of putting more energy into, external constraint component and core plate, ribbed stiffener and put more energy into floor no longer jointly by
Power, external constraint component axial rigidity is not as a part for buckling restrained brace integral rigidity, buckling restrained brace rigidity hair
After changing, can lift structure damping effect.
In the utility model, the size of external loads input is calculated by core plate tension and compression reciprocating stroke distance, is rationally set
At the time of pulley groove slope angle is put so as to control stiffness variation.When buckling restrained brace integral rigidity is undergone mutation, core plate tension and compression become
Shape is too fast, excessive, influences buckling restrained brace energy-dissipating property, put more energy into floor and external constraint component inside band groove steel plate it
Between set lead for retractable pencil material to carry out the energy of dissipative part Seismic input, slow down core plate moment tension and compression deformation.
