Background technology
Primary structure and the principle of existing triangular steel plate damper are as follows.First, for providing reliable constraint to triangular steel plate 1-1, junction plate 1-2 need be slotted, and being connected by twin fillet wolt; Secondly, limiting plate 1-5 and junction plate 1-6 is connected to become entirety by twin fillet wolt; Finally, triangular steel plate 1-1 being connected with square sleeve 1-3, and being installed between limiting plate 1-5 by bearing pin 1-4, for ensureing stability, thin plate 1-7 can be added between square sleeve 1-3 and limiting plate 1-5.This production method can cause following problem:
The first, the contact between bearing pin 1-4 and limiting plate 1-5 is linear contact lay, and this concentrates bringing serious stress, causes local stress in spacing plate hole much larger than other positions, and enters surrender in advance, will cause serious fatigue damage under dynamic loading;
The second, due to the existence that stress is concentrated, when being subject to more energetically, the energy dissipation capacity of damper weakens, and even loses efficacy;
Three, the axis direction along bearing pin does not have reliable spacing measure, can produce movement in the axial direction at dynamic loading lower bearing pin, and finally departs from limiting plate 1-5 and cause damper to lose efficacy;
4th, for playing good energy consumption effect, existing triangular steel plate damper need be combined with the support had compared with large rigidity, is a kind of waste to support, and damper is born more energetically and then increases the weight of stress to concentrate in comparatively thin tail sheep situation.
Summary of the invention
The object of the invention is in order to solve existing damper stress concentrate and lack necessary spacing measure and bring respectively in the problem of exerting oneself greatly and power reciprocating load bottombearing damper lost efficacy, and then provide a kind of triangular steel plate damper.
Technical scheme of the present invention is: a kind of triangular steel plate damper comprises junction plate, junction plate, two pieces of limiting plates, multiple triangular steel plate and multiple square sleeve, junction plate offers multiple bar hole side by side, each bar hole is fixedly embedded with a triangular steel plate, the lower end of each triangular steel plate is fixedly connected with a square sleeve, two pieces of limiting plates are vertically fixed on junction plate, two pieces of limiting plates offer multiple installing hole respectively, multiple square sleeve is between two pieces of limiting plates, described triangular steel plate damper also comprises multiple T-shaped bolt and multiple nut, each T-shaped bolt includes axle head connector and threaded bearing pin, axle head connector is vertically arranged, threaded bearing pin level is fixedly connected on axle head connector, each threaded bearing pin to be located in a square sleeve and to stretch out square sleeve, nut driving is on the threaded bearing pin stretching out square sleeve part, axle head connector is installed in an installing hole of wherein one piece of limiting plate, nut is installed in an installing hole of another block limiting plate.
Described axle head connector is the connector that the side end face of being cut by cuboid has that rectangular contact face and upper and lower two ends are semicircle transition face, and the outer shape of axle head connector is with the internal via shape of installing hole and match.
The present invention compared with prior art has following effect:
1. T-shaped bolt of the present invention is that face contacts by axle head connector and the way of contact between nut with the installing hole on limiting plate, and be linear contact lay between existing column type bearing pin and installing hole, by line to face, contact area increases decades of times, and then avoiding the stress concentration phenomenon existed in existing damper, exerting oneself of damper is effectively improved.
2. the present invention is while avoiding stress to concentrate, and extends fatigue life and the length of service of damper, and effectively can improve the energy dissipation capacity of damper in situation of exerting oneself greatly.
3. between the installing hole of T-shaped screw bolt and nut of the present invention on limiting plate, only relative sliding vertically and not existing relatively rotates, and the length of T-shaped screw bolt and nut is greater than square sleeve aperture, spacing effect can be played to bearing pin, therefore under the prerequisite do not lost efficacy at limiting plate, T-shaped screw bolt and nut is positioned at the installing hole of limiting plate all the time, to glide out the installing hole of limiting plate and the phenomenon causing damper to lose efficacy from improving existing damper at dynamic loading long term.
4. adopt hinged between triangular steel plate of the present invention and T-shaped bolt, and T-shaped bolt and limiting plate can produce vertical relative sliding, can avoid film effect.
