Utility model content
Technical problem to be solved in the utility model is to provide and a kind ofly can ensures that damper has stable Hysteresis Behavior, avoids occurring intersecting the shock-resistant and energy-dissipating device of weld seam phenomenon in power consumption plate both sides same position.
For realizing above-mentioned technique effect, the utility model discloses a kind of shock-resistant and energy-dissipating device, comprise power consumption plate and be located in the framework on described power consumption plate surrounding end face, described power consumption plate comprises a leading flank and a trailing flank, on described leading flank, be welded with lateral stiffening plate, and be formed with transverse weld between described lateral stiffening plate and described power consumption plate, on described trailing flank, be welded with vertical stiffener, and be formed with vertical weld seam between described vertical stiffener and described power consumption plate, in the crossover location place of described vertical weld seam and described transverse weld, on described vertical stiffener, be provided with the groove caving inward.
The utility model is owing to having adopted above technical scheme, making it have following beneficial effect is: by the groove caving inward is set on vertical stiffener, dodge the crossover location of vertical weld seam and transverse weld, thereby avoid occurring in the both sides same position of power consumption plate the intersection weld seam of vertical weld seam and transverse weld simultaneously, avoid consuming energy plate by through welding, and the performance of major injury power consumption plate.
The utility model further improves and is, described power consumption plate comprises four end faces up and down, described framework comprises the horizontal connecting plate of being located at respectively in the upper and lower both ends of the surface of described power consumption plate, and be located at respectively the frange plate in the both ends of the surface of described power consumption plate left and right, the two ends up and down of described frange plate are fixedly connected with described horizontal connecting plate respectively.
The utility model further improves and is, the two ends of described lateral stiffening plate are individually fixed on described frange plate, and the two ends of described vertical stiffener are individually fixed on described horizontal connecting plate.
The utility model further improves and is, described groove surfaces is circular arc.The circular groove of surface smoothing, because there is no corner angle, can not cause extra stress to concentrate, and can not interfere with the performance of power consumption plate.
The utility model further improves and is, described groove is polygon.
The utility model further improves and is, described power consumption plate is made up of mild steel.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail.
First consult shown in Fig. 1～3, a kind of shock-resistant and energy-dissipating device of the present utility model mainly comprises a power consumption plate 11 for energy-dissipating and shock-absorbing, be located in power consumption plate 11 framework on four end faces up and down, and is located at the lateral stiffening plate 14 on power consumption plate 11 leading flanks and is located at the vertical stiffener 15 on power consumption plate 11 trailing flanks.
Wherein, coordinate shown in Fig. 4～6, framework is by being welded in respectively power consumption plate two horizontal connecting plates 12 in both ends of the surface Shang Xia 11, and two frange plates 13 that are welded in respectively in power consumption plate 11 left and right both ends of the surface form, and the two ends up and down of frange plate 13 are welded to connect with horizontal connecting plate 12 respectively, thereby be fixedly located in power consumption plate 11 outsides.Framework is bolted or welding is connected with building structural element, power consumption plate 11 is arranged on building structural element, to realize the energy-dissipating and shock-absorbing effect of power consumption plate 11 to building structural element.
