Description
Technical field
The present invention relates to a kind of energy dissipation and support device, particularly relate to a kind of preparatory tensile of double-core that increases span from resetting energy dissipation and support device.
Background technology
The shatter-proof design of present stage, except needing enough allowable strengths, more hoping has good toughness, to reach more economical and safer purpose.With regard to regard to the structural system of subduing energy dissipating, can after large deformation, cause remaining permanent deformation usually, make building that remaining stress arranged, cause potential danger, needing in the future, maintenance solves this problem.Present common support system subdues or frustrates that to bend energy dissipating be main with structural member, but under load-carrying repeatedly, subdues or frustrate the distortion that causes in the wrong, can influence safety and the degree of difficulty in rescue on the fabric structure.Bundle system in the wrong is subdued behavior and friction behavior is master's energy dissipating support research and application to frustrate, existing in many aspects concrete achievement, but these two kinds of energy dissipating behavior rod members also just can't solve the problem of permanent set all not from the function that resets.The system that therefore can reset certainly at present is main developing direction, and the reliable spring of the method that resets certainly or the mode of preparatory power are implemented.
Disclosed a kind of device of exerting pressure in No. 5819414 patent of U.S. bulletin, made the device global behavior be similar to spring and have, and produced the energy dissipating effect with the contact friction of intermediate article from the function that resets with the mode of bundle system.
See also Fig. 1 to shown in Figure 7, disclosed No. 2008/0016794 patent of the U.S. disclosed and a kind ofly with the mode of drawing preparatory power the device from reset function is provided.For convenience of explanation, Fig. 1 to Fig. 7 gives element numbers again.The side cut away view that Fig. 1 installs for this reason, Fig. 2 is the sectional drawing of section A-A.Device comprise internal layer base plate 12, a cover that inner core member 11, that a square steel is formed is fixed in first end of this inner core member 11 be overlying on inner core member 11 outer and equally by the square steel forms outer component 13, be fixed in the outer bottom 15 and 16 at these outer component 13 two ends and anchor ingot device 21 and preparatory power rod member 22.Inner core member 11 also have one in order to building framework in beam and column connected extension 111; 13 of outer components have two in order to building framework in beam and column connected extension 131.The friction energy dissipating plate 132 of the energy dissipating plate 112 in the inner core member 11, outer component 13, and the combination of angle steel 133 usefulness bolts 14, and rub energy dissipating to the relative displacement utilization of inner core member 11 and outer component 13.
Aspect the mechanics reaction, please consult Fig. 3 earlier to shown in Figure 5.Do not receive external force when installing, mechanical behavior is as shown in Figure 3.When the device pressurized; Inner core member 11, internal layer base plate 12 and outer component 13 are the compressed member in the device, and external force is as shown in Figure 4, are passed to the outer bottom 15 of offside by the extension, two ends 131 of outer component 13; Via outer bottom 15 and anchor ingot device 21 power is reached preparatory power rod member 22 again; Preparatory power rod member 22 is drawn, and strength is reached on the other end base plate 16, by inner core member 11 and extension 111 power is spread out of again.Can know to execute and carry down that outer component 13 has relative displacement δ with inner core member 11 by Fig. 5, energy dissipating plate capable of using 112, energy dissipating plate 132, angle steel 133 and bolt 14 energy dissipatings at external force F.
See also Fig. 6 and shown in Figure 7 again.When device is drawn, power member 22, anchor ingot device 21 and two outer bottoms 15 and 16 are tensional element in advance, and external force is as shown in Figure 6; Extension, two ends 131 by outer component 13; Reach on the outer bottom 16 via outer component 13, via outer bottom 16 and anchor ingot device 21 strength is reached preparatory power rod member 22 again, it is drawn; And strength reached on the other end outer bottom 15, reach the extension 111 of inner core member 11 again.Can know to execute and carry down that outer component 13 has relative displacement δ with inner core member 11 by Fig. 7, energy dissipating plate capable of using 112, energy dissipating plate 132, angle steel 133 and bolt 14 energy dissipatings at external force F.
This device utilizes the restoring force of preparatory power that permanent set is eliminated under earthquake.But be subject to the material property of tension member, this device axial deflection only limits to δ.
