Description
Technical field
The utility model belongs to field of civil engineering, is specially a kind of two-way energy-dissipating and shock-absorbing mild steel damper, can be applied to civil structure shockproof control field.
Background technology
The main power consumption principle of mild steel damper is the dynamic response by metal material Hysteresis Behavior control structure good after entering elastic-plastic range.Which utilizes mild steel and there is excellent plastic deformation ability, can under the plastic strain exceeding yield strain tens times reciprocal transformation hundreds of time and do not rupture, reach the object of energy-dissipating and shock-absorbing in the process.
The mild steel damper of current design comprises rectangle, triangle, X-type, hollow diamonds etc., but they all can only play the effect of energy-dissipating and shock-absorbing at the fixed-direction of vertical monolithic according to position, and when larger relative displacement occurs orthogonal direction, easily there is shear failure in mild steel damper.
Utility model content
The purpose of this utility model is the mild steel damper proposing a kind of two-way energy-dissipating and shock-absorbing, this device utilizes the excellent energy dissipation behavior of hollow diamonds mild steel damper, and improved, be arranged in a kind of framework be made up of upper and lower cover plates and groove by four pieces of hollow diamonds mild steel damper single-sheet symmetrics, top adopts the mode of riveted joint to connect, and bottom is retrained by groove.Under the External Force Actings such as earthquake, when upper and lower cover plates to produce the relative displacement of a direction with interlayer, the mild steel damper monolithic that web surface is vertical with this relative displacement direction can bend and surrender and energy-dissipating and shock-absorbing, the web surface mild steel damper monolithic parallel with this relative displacement direction can skid off along groove, can not affect overall shock absorbing characteristics or destroy.
To achieve these goals, the utility model takes following technical scheme.
The two-way energy-dissipating and shock-absorbing mild steel damper of the one that the utility model proposes, by upper cover plate 1, top rivet 2, mild steel damper monolithic 3, groove 4, bottom rivet 5 and lower cover 6 form, wherein: upper cover plate 1 and lower cover 6 are circular sheet, mild steel damper monolithic 3 is by upper flange 7, hollow diamonds web 8 and lower wing plate 9 form, hollow diamonds web 8 is between upper flange 7 and lower wing plate 9, groove 4 comprises two pieces of groove monolithics 10 be arranged symmetrically with, each groove monolithic 10 cross sectional shape is " z " shape, gap is left between two groove monolithics 10 be arranged symmetrically with, mild steel damper monolithic 3 totally 4, pairwise orthogonal radial symmetric along upper cover plate 1 and lower cover 6 is arranged, the upper flange 7 of mild steel damper monolithic 3 is connected with upper cover plate 1 by top rivet 2, lower wing plate 9 puts into the gap location between two groove monolithics 10 from the side, and be connected with lower cover 6 by bottom rivet 5.
In the utility model, mild steel damper monolithic 3 is common low carbon Steel material, and its width is 50% ~ 100% of groove monolithic 10 length, and it is highly 1.5 ~ 2 times of width.The length of groove monolithic 10 is 60% ~ 80% of lower cover 6 radius.
In the utility model, mild steel damper monolithic upper flange 7 is connected with upper cover plate 1 by top rivet 2, groove 4 is connected with lower cover 6 by bottom rivet 5, the relative displacement this ensures that thering interlayer can be delivered on mild steel damper monolithic 3 effectively, avoids on mild steel damper web 8 perforate to realize and the riveted joint of framework and the problem such as the pressure that produces is concentrated simultaneously.
The two-way energy-dissipating and shock-absorbing mild steel damper of the one that the utility model proposes, by the combination of hollow diamonds mild steel damper is arranged in a kind of framework be made up of upper and lower cover plates and groove, form one and effectively to the new dashpot system pairwise orthogonal direction of relative displacement occurs plaing to the structure that relative displacement all occurs in pairwise orthogonal direction energy-dissipating and shock-absorbing effect, larger practical value can be had.
Effect of the present utility model is: under the External Force Actings such as earthquake, when upper and lower cover plates to produce the relative displacement of a direction with interlayer, the mild steel damper monolithic that web surface is vertical with this relative displacement direction can bend and surrender and energy-dissipating and shock-absorbing, the web surface mild steel damper monolithic parallel with this relative displacement direction can skid off along groove, can not affect overall shock absorbing characteristics or destroy.Such one side can strengthen the reliability and stability of whole shock absorption system, can not cause the relative displacement due to a direction that the mild steel damper worked at its orthogonal direction is destroyed, thus cause continuing cannot work when there is its orthogonal direction relative displacement, thus can not play the consequence of energy-dissipating and shock-absorbing effect.On the other hand also save cost, practicality and economy stronger.

Detailed description of the invention
Detailed description of the invention of the present utility model is described in detail below in conjunction with accompanying drawing.
Embodiment 1: as shown in the figure, comprises upper cover plate 1, top rivet 2, mild steel damper monolithic 3, groove 4, bottom rivet 5 and lower cover 6.Upper cover plate 1 and lower cover 6 are circular sheet, and upper cover plate 1 and lower cover 6 have the first circular hole.Mild steel damper monolithic 3 comprises upper flange 7, hollow diamonds web 8 and lower wing plate 9, wherein upper flange 7 has the second circular hole.Groove 4 comprises two pieces of groove monolithics 10 be arranged symmetrically with, and groove monolithic 10 has the 3rd circular hole.Mild steel damper monolithic 3 totally 4, the pairwise orthogonal radial symmetric along upper cover plate 1 and lower cover 6 is arranged.Top rivet 2 is through the first circular hole on upper cover plate and the second circular hole on upper flange 7, and the upper flange 7 of mild steel damper monolithic 3 and upper cover plate 1 are coupled together, lower wing plate 9 puts into groove 4 from the side.Groove monolithic 10 cross sectional shape is " z " shape, can first will be all connected with lower cover 6 with bottom rivet 5 by the groove 4 that the symmetrical groove monolithic 10 placed forms between two, then respectively the lower wing plate 9 of 4 pieces of mild steel damper monolithics 3 is inserted in groove 4, and upper flange 7 top rivet 2 is connected with upper cover plate 1.Under the External Force Actings such as earthquake, when upper and lower cover plates to produce the relative displacement of a direction with interlayer, the mild steel damper monolithic that web surface is vertical with this relative displacement direction can bend and surrender and energy-dissipating and shock-absorbing, the web surface mild steel damper monolithic parallel with this relative displacement direction can skid off along groove, can not affect overall shock absorbing characteristics or destroy.
Mild steel damper monolithic 3 is common low carbon Steel material, mild steel damper monolithic upper flange 7 to be connected with upper cover plate 1 by top rivet 2 and to realize consolidation, groove 4 to be connected with lower cover 6 by bottom rivet 5 and, groove to mild steel damper monolithic have vertical direction and and the constraint of its web surface vertical direction, the relative displacement this ensures that thering interlayer can be delivered on mild steel damper monolithic 3 effectively, the upper lower wing plate of the mild steel damper monolithic making web surface direction vertical with this relative displacement direction produces relative displacement thus yield deformation energy-dissipating and shock-absorbing occurs, there is not relative displacement in the upper lower wing plate of the mild steel damper monolithic that web surface direction is vertical with this relative displacement direction, but entirety skids off along groove translation.
