Mild steel yielding intensity is low, stable performance, and cheap, has good anti-low cycle fatigue property, and percentage elongation is big, Plastic deformation ability is relatively strong, has good hysteretic characteristic, can absorb substantial amounts of energy after entering mecystasis, is suitable for manufacturing Various types of energy-consumption shock-absorption devices.Mild steel is used to improve the shock resistance of building in a lot of states with Japan as representative at present Family and area are widely popularized.Mild steel damper is to utilize the feature that mild steel yielding intensity is low, plastic deformation ability is strong to make A kind of passive energy-dissipating device
Summary of the invention
Present invention aim at providing a kind of multi-dimensional direction surrender power consumption mild steel sinker, solving existing sinker can only face In or the problem that consumes energy of face outer single direction surrender.
For achieving the above object, the technical scheme that the present invention provides is as follows:
The invention provides a kind of multi-dimensional direction surrender power consumption mild steel sinker, including top board, multiple power consumption part and the end Plate, described power consumption part is arranged between described top board and described base plate.Described power consumption part axle center section is symmetrical parabolic profile, Multiple plastic yield-point can be formed under geological process;Cross section is circular, has centre symmetry, in horizontal plane each Direction has identical mechanical property, it is possible to realize the surrender power consumption of multi-dimensional direction.
Preferably, described power consumption part material is Low Yield Point Steel, uses perforation plug welding to be connected with top board, base plate.
Preferably, described multi-dimensional direction surrender power consumption mild steel sinker, also include connecting plate.
Preferably, described connecting plate is arranged at the lower surface of described base plate.
Preferably, described connecting plate uses with described base plate and is welded to connect.
Further, described multi-dimensional direction surrender power consumption mild steel sinker, also include edge girder, edge posts and support.
Preferably, described connecting plate and described support, described top board and described edge girder all use the connection of high-strength bolt Mode, it is simple to the installation of device, dismantle, keep in repair and shake after change.
Compared with prior art, present invention have an advantage that
The multi-dimensional direction surrender power consumption mild steel sinker that the present invention provides, its power consumption part axle center section is outside symmetrical parabolic Shape, it is possible to form multiple plastic yield-point under geological process, cause stresses re-distribution, effectively improves stress and concentrates effect Should, strengthen its plastic deformation ability and low cycle fatigue property, improve the utilization rate of material.Secondly, the cross section of power consumption part is circle Shape, has centre symmetry, and in horizontal plane, all directions have identical mechanical property, it is possible to realize the surrender of multi-dimensional direction Power consumption.Finally, the present invention provides multi-dimensional direction surrender power consumption mild steel sinker and building structure use the connection of high-strength bolt Mode, it is simple to the installation of device, dismantle, keep in repair and shake after change.
The multi-dimensional direction surrender power consumption mild steel sinker that the present invention provides is nonload bearing element, it is impossible to enough undertake building structure Weight, after sinker is installed, do not change the vertical applied force system of major structure of construction.

Detailed description of the invention
The multi-dimensional direction surrender power consumption mild steel sinker proposed the present invention below in conjunction with accompanying drawing and instantiation is made into one Step describes in detail.It should be noted that, accompanying drawing all uses the form simplified very much and all uses non-ratio accurately, only in order to side Just, the purpose that the present invention implements is aided in illustrating lucidly.
As Figure 1-3, the multi-dimensional direction surrender power consumption mild steel sinker provided for the present invention, including top board 1, multiple consumption Energy part 2 and base plate 3, described power consumption part 2 is arranged between described top board 1 and described base plate 3.Described power consumption part 2 axle center section For symmetrical parabolic profile, it is possible to form multiple plastic yield-point under geological process;Cross section is circular, has centrosymmetry Property, in horizontal plane, all directions have identical mechanical property, it is possible to realize the surrender power consumption of multi-dimensional direction.
Preferably, described power consumption part 2 material is Low Yield Point Steel, uses perforation plug welding to be connected with top board 1, base plate 3.
