Utility model content
For the above-mentioned problems in the prior art, the utility model provides a kind of shearing type damper, this shearing type damper is provided with breach on its cant board, at the middle part of cant board, deformation occurs being subject to bootable shearing type damper of the present utility model under effect more energetically.
For solving the problem, the technical solution adopted in the utility model is:
A kind of shearing type damper, comprise: upper junction plate, lower connecting plate and the central layer be connected between described upper and lower junction plate, it is characterized in that, two ends, described central layer left and right are also respectively equipped with cant board, described cant board upper end is connected with described upper junction plate, described cant board lower end is connected with described lower connecting plate, and the two ends that described cant board is not connected with described upper junction plate and lower connecting plate are also provided with breach.
As preferably, described upper junction plate and described lower connecting plate be arranged in parallel, and described central layer is a rectangular slab and perpendicular to described upper and lower junction plate, described cant board is vertical with described central layer.
As preferably, described breach is positioned at the middle part of described cant board.
As preferably, described breach is multiple.
As preferably, described breach runs through described cant board completely and is divided into multiple part.
As preferably, described central layer plate face is provided with sash rib.
As preferably, described central layer plate face is equipped with sash rib and vertical stiffening rib.
As preferably, described central layer plate face is provided with vertical stiffening rib.
Compared with prior art, the beneficial effects of the utility model are: the shearing type damper that the utility model provides, by changing shape and the structure of cant board, distortion is guided to occur at the middle part of cant board, the region of stress concentration of cant board end is effectively spread, can ensure, under the prerequisite that damper is stressed, farthest to improve its deformability.

Detailed description of the invention
For making those skilled in the art better understand the technical solution of the utility model, below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As shown in Figure 1, a kind of shearing type damper, comprise: upper junction plate 1, lower connecting plate 2 and the central layer 3 be connected between upper and lower junction plate, central layer about 3 two ends are also respectively equipped with cant board 4, cant board 4 upper end is connected with upper junction plate 1, cant board 4 lower end is connected with lower connecting plate 2, and the arbitrary end at cant board about 4 two ends (i.e. the other two ends of relative upper/lower terminal) is also provided with the breach 41 (this breach 41 can be also can be multiple) running through cant board plate face; For avoiding the stress raisers at breach 41 place, in preferred embodiment of the present utility model, the inner port of breach 41 is fillet.
Preferred construction as shearing type damper is arranged, wherein: upper junction plate 1 and lower connecting plate 2 be arranged in parallel, central layer 3 is a rectangular slab and welds perpendicular to upper and lower junction plate, cant board 4 is vertical with central layer 3, and the upper end of cant board 4 is welded with the lower face of upper junction plate 1, lower end is welded with the upper face of lower connecting plate 2.In prior art, the cross section of cant board 4 mostly is rectangle, is wherein also no lack of the cross section having other shapes.And in the utility model, except arranging except breach 41 on cant board 4, also change the structure of cant board 4, as shown in Figures 2 to 4, two end sections of cant board 4 will want large compared with the section area at middle part, in the structure of a similar I shape.
Continue composition graphs 2,3,4, shearing type damper of the present utility model, for guiding its deformation to occur at the middle part of cant board 4, as preferably embodiment, breach 41 is positioned at the middle part at the two ends, left and right of cant board 4; Preferably, breach 41 be set to multiple can effective dispersive stress concentrated area, optimize internal force distribution, significantly improve the deformability of damper, wherein, the length of breach 41 can adjust accordingly according to the actual requirements, namely breach 41 can run through cant board 4, also can not run through cant board 4.As shown in Figure 2, the structural representation of the cant board of the first embodiment of the present utility model, when the length of breach 41 runs through cant board 4 completely, cant board 4 is divided into upper and lower two relative T-type structures by breach 41.Certainly, if breach 41 is more than three, and three breach 41 run through cant board 4 all completely, then cant board 4 is divided into multiple part independent of each other by breach 41.As shown in Figure 3, the structural representation of the cant board of the second embodiment of the present utility model, the length of breach 41 not as good as the half of breadth of section in the middle part of cant board 4, and when cant board about 4 two ends are equipped with breach 41, preferably, the breach at two ends, left and right is crisscross arranged.As shown in Figure 4, the structural representation of the cant board of the 3rd embodiment of the present utility model, because cant board more than 4 of the prior art adopts square-section, but in order to the technique effect that the utility model is mentioned can be reached, breach 41 can be set up in the basis of direct rectangular side riser 4 in the prior art, facilitate the improvement of existing cant board 4.Certainly, breach 41 can be one or more, also can run through cant board 4 completely.
For strengthening supporting capacity and the deformation rigidity of central layer 3 further, as preferably embodiment, shearing type damper of the present utility model, central layer plate face is provided with sash rib 5, also only can be provided with vertical stiffening rib 6, sash rib 5 and vertical stiffening rib 6 can select a setting, also can arrange simultaneously, as shown in Figure 1, in the preferred embodiment that the utility model provides, sash rib 5 and vertical stiffening rib 6 all have setting on central layer 3.
Above embodiment is only exemplary embodiment of the present utility model, is not used in restriction the utility model, and protection domain of the present utility model is defined by the claims.Those skilled in the art can in essence of the present utility model and protection domain, and make various amendment or equivalent replacement to the utility model, this amendment or equivalent replacement also should be considered as dropping in protection domain of the present utility model.
