Abstract
The utility model relates to an oval steel and lead energy dissipater. The oval steel and lead energy dissipater is characterized by comprising an upper connection plate, a lower connection plate, a stainless steel tube and a lead core. The stainless steel tube is a hollow oval thin-wall steel tube, and the two ends of the stainless steel tube are sealed through the upper connection plate and the lower connection plate respectively. The lead core is completely wrapped in the closed space formed by the stainless steel tube, the upper connection plate and the lower connection plate. The oval steel and lead energy dissipater is simple in structure, easy to machine and good in energy dissipation performance, and has the same performance as a common soft steel energy dissipater or the better performance than the common soft steel energy dissipater. The oval steel and lead energy dissipater is made of stainless steel and lead, so that the manufacturing cost is much lower than that of the low-yield-limit soft steel energy dissipater.
Description
Technical field
The present invention relates to the metal energy-dissipating device of a kind of energy dissipation unit, particularly a kind of low-yield---the plumbous energy comsuming device of oval steel, is applied to various structures and mechanical passive energy dissipation.
Background technique
Steel-lead energy dissipator combines the advantage of ringmild steel energy dissipator and plumbous energy comsuming device, the plumbous constraint that is subject to outside steel pipe in loading process, the pure plumbous energy comsuming device of Performance Ratio is superior, and the reason that encased steel plate is filled with plumbous due to inside is difficult for bending deformation, thereby can reduce the yield point of cross section reduction energy comsuming device, make it be easier to enter plasticity power consumption.Utilize like this plain carbon steel and plumbous combination to reach the yield point lower than common ringmild steel energy dissipator, thereby improve the performance of Metallic damper, cost-saving.
On October 19th, 2005, State Intellectual Property Office announced " steel-lead energy dissipator " patent of invention number: 200510033467.7, the disclosed technological scheme of this patent application is by stainless steel and the plumbous steel-lead energy dissipator forming, it is characterized in that the hollow i-shape component of described corrosion resistant plate, two ends are respectively with upper junction plate and lower connecting plate sealing, described lead is wrapped in the confined space of corrosion resistant plate, upper junction plate and lower connecting plate composition completely, and described patent is the shear action dissipation energy utilizing between upper junction plate and lower connecting plate.This patent of invention has well been utilized stainless steel and plumbous energy-dissipating property, but because being designed to the plumbous energy comsuming device of steel of I shape, be subject under external excitation effect, the easy getting up early drum of crossing of I shape encased steel plate is out of shape, web steel plate is easy to bending deformation, and it is reduced inner plumbous effect of contraction, thereby member energy-dissipating property reduces.
Summary of the invention
In view of the deficiency that prior art exists, technical problem to be solved by this invention is to improve the stability of stainless steel outer packed plate, and its unlikely getting up early drum of crossing is out of shape, and retrains the inner lead pouring into, to improve the energy-dissipating property of member; Member processing simultaneously proposed by the invention is more easy.
To achieve these goals, technological scheme of the present invention is: the plumbous energy comsuming device of a kind of oval steel, comprise upper junction plate (1), lower connecting plate (2) and be arranged at upper junction plate (1) and lower connecting plate (2) between Stainless Steel Tube (3), described Stainless Steel Tube (3) middle part is provided with lead for retractable pencil (4), described Stainless Steel Tube (3) is hollow ellipse shape Sheet Steel Pipe, two ends are tightly connected with upper and lower connecting plate respectively, and described lead for retractable pencil (4) circle wraps in the enclosed space of Stainless Steel Tube (3) and upper junction plate (1), lower connecting plate (2) composition.
Further, between described Stainless Steel Tube (3) and upper junction plate (1), lower connecting plate (2), adopt and be welded to connect.
Further, described upper junction plate (1) is provided with fills with plumbous hole (6) and exhaust port (7), and the plumbous hole of described filling (6) diameter is greater than exhaust port (7) diameter.
Further, the plumbous hole of described filling (6) and exhaust port (7) are provided with the bolt of filling with plumbous hole (6) and exhaust port (7) for sealing.
Compared with prior art, advantage of the present invention is:
(1) overall structure is simple, easy to process, is conducive to reduce manufacture cost.
(2) make full use of steel and plumbous good mechanical property, obtain the energy comsuming device that energy-dissipating property is good.
(3) combination of the steel lead by elliptical shape obtains a kind of energy comsuming device of low yield strength, effectively avoid existing web steel plate to be easy to bending deformation, and it is reduced inner plumbous effect of contraction, thus the defect that member energy-dissipating property reduces, than the object that reaches wind resistance and antidetonation and energy dissipating.

Embodiment
As shown in Figure 1, 2, 3, the plumbous energy comsuming device of oval steel of the present invention comprises upper junction plate (1), lower connecting plate (2), oval Stainless Steel Tube (3) and lead for retractable pencil (4); Oval Stainless Steel Tube (3) be hollow thin-wall pipe, and use respectively at two ends, lower connecting plate (1), (2) seal; Described lead for retractable pencil (4) is wrapped in the enclosed space of oval Stainless Steel Tube (3) and upper junction plate (1), lower connecting plate (2) composition completely.
Between described oval Stainless Steel Tube (3) and upper junction plate (1), lower connecting plate (2), adopt and be welded to connect.
Described upper junction plate is provided with fills with plumbous hole (6) and exhaust port (7).Upper and lower connecting plate is Q235 steel, and upper and lower connecting plate is reserved attachment hole (5) respectively, is convenient to be connected with structure and support with bolt.
When use, for security consideration, after filling with lead, can seal and fill with plumbous hole (6) and exhaust port (7) by bolt.
The plumbous energy comsuming device of oval steel of the present utility model is applied to the position of structure or machinery generation relative deformation, and due to the vibration of structure or machinery, energy comsuming device will be subject to relative shear power, as shown in Figure 1.Under shearing force effect, on energy comsuming device, lower connecting plate produces relative deformation, and lead for retractable pencil enters plastic yield very soon, and under reciprocating load, energy comsuming device carries out hysteretic energy, thereby reduces the vibration of structure or machinery.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
