Description

The efficient energy-consumption damper of metal
Technical field
The present invention relates to energy-consuming shock absorbers, more particularly, to a kind of efficient energy-consumption damper of metal.
Background technology
Common metal damper is that will have the metal derby compared with low-yield and be connected to building by additional support rod piece In structure, play energy-dissipating and shock-absorbing.When building structure is under the incentive action of earthquake, additional support rod piece hinders common metal Buddhist nun's device acts, and when the common metal damper is surrendered, will generate plastic deformation, thus the seismic energy of consumption s tructure, To achieve the purpose that damping.But before common metal damper surrender, which will produce flexible deformation, and Will not earthquake energy increase the rigidity of building structure, instead on the contrary due to being applied with elastic component in building structure The earthquake response of building structure can be caused to increase, therefore in order to improve damping effect, the common metal damper should be allowed to bend as early as possible Clothes generate plastic deformation, and the plastic deformation that reason does not generate fails beyond allowable range, to reach the mesh of lasting damping 's.It can be seen that common metal damper can not meet this requirement.
Invention content
It can as early as possible surrender under geological process the purpose of the present invention is to provide a kind of, plastic deformation can be generated and largely disappear Consumption seismic energy and non-reason consume energy and generating excessive plastic deformation leads to failure, to reach the gold of lasting damping purpose Belong to efficient energy-consumption damper.
The object of the present invention is achieved like this:

Specific implementation mode
With reference to embodiment and compares attached drawing invention is further described in detail.
A kind of efficient energy-consumption damper of metal, by be mild steel be made 1-5 energy consumption rod piece (AB, EF, GH, CD, JK it) is formed with 1-4 gusset plates, the upper end of the upper end of the 1st energy consumption rod piece A B and the 4th energy consumption rod piece CD are bolted on In Section 1 contact plate 1, the lower end of the lower end of the 2nd energy consumption rod piece EF and the 3rd energy consumption rod piece GH are bolted on Section 3 point On plate 3, the upper end of the lower end of the 1st energy consumption rod piece A B and the 2nd energy consumption rod piece EF are bolted in Section 2 contact plate 2, the The lower end of 4 energy consumption rod piece CD and the upper end of the 3rd energy consumption rod piece GH are bolted in Section 4 contact plate 4, the 1st energy consumption bar Part, the 2nd energy consumption rod piece, the 3rd energy consumption rod piece and the 4th energy consumption rod piece it is end to end, constitute diamond shape, and in up and down, left and right it is symmetrical The angle of arrangement, the 1st energy consumption energy consumption rod piece 2 of rod piece 1 and the 2nd is obtuse angle, the angle of the 3rd energy consumption energy consumption rod piece 4 of rod piece 3 and the 4th Upper end for obtuse angle, the 5th energy consumption rod piece JK is bolted in Section 1 contact plate 1, and the lower end of the 5th energy consumption rod piece JK passes through Bolt is fixed in Section 3 contact plate 3, long axis diagonal lines of the 5th energy consumption rod piece JK as diamond shape;One end of 1st installation bearing diagonal 5 It is fixed on first corner top in room, the other end of the 1st installation bearing diagonal 5 is fixed in Section 2 contact plate 2, and the 2nd installation is oblique One end of support 6 is fixed on the room second corner top opposite with first corner top, and the 2nd installs the another of bearing diagonal 6 One end is fixed in Section 4 contact plate 4, and the 1st installation bearing diagonal 5 and the 2nd installation bearing diagonal 6 are in alignment, the 3rd installation bearing diagonal 7 is vertical with the 1st installation installation bearing diagonal 6 of bearing diagonal the 5, the 2nd, and one end of the 3rd installation bearing diagonal 7 is fixed on the third wall in room The other end on angle top, the 3rd installation bearing diagonal 7 is fixed in Section 1 contact plate 1 or Section 3 contact plate 3.
Operation principle:Force analysis is as shown in Figure 2.
Assuming that the left and right ends of the damper are respectively by a horizontal pull F, then the 1st energy consumption rod piece A B, the 2nd energy consumption bar Part EF, the 3rd energy consumption rod piece GH, the 4th energy consumption rod piece CD internal force be respectively:
The internal force of 5th energy consumption rod piece JK is:N2=-tg θ F
When θ=45 °,N2=-F
If taking the cross section face of the 1st energy consumption rod piece A B, the 2nd energy consumption rod piece EF, the 3rd energy consumption rod piece GH, the 4th energy consumption rod piece CD Product is
Then the 1st energy consumption rod piece A B, the 2nd energy consumption rod piece EF, the 3rd consumption rod piece GH, the 4th energy consumption rod piece CD and the 5th energy consumption rod piece JK can be surrendered simultaneously at θ=45 °.
In the present embodiment, θ is taken>45 ° (such as θ=60 °), and it is A to take the cross-sectional area of bar AB, CD, GH, EFs1= 0.707As2, then N1>0.707F, N2>F can make the 1st energy consumption rod piece A B, the 2nd energy consumption rod piece EF, the 3rd under horizontal pull F effects Energy consumption rod piece GH, the 4th energy consumption rod piece CD and the 5th energy consumption rod piece JK can be surrendered as early as possible, and can more effectively dissipate seismic energy, reach To the purpose efficiently to consume energy.
If when design, making the 1st energy consumption rod piece A B, the 2nd energy consumption rod piece EF, the 3rd consumption rod piece GH, the 4th energy consumption rod piece CD not Energy consumption is participated in, the 5th energy consumption rod piece JK energy consumptions are left behind, then to reach the 1st energy consumption rod piece A B, the 2nd energy consumption rod piece EF, the 3rd consumption bar Part GH, the 4th energy consumption rod piece CD participate in the identical energy consumption that consumes energy, then the 5th energy consumption rod piece JK must generate sufficiently large plasticity and become Shape, it is possible to the deformation limit beyond the 5th energy consumption rod piece JK and so that damper is failed, this is improper.
