Description

A kind of metal damper of Self-resetting bending energy-wasting
Background technique
The invention belongs to metal damper field more particularly to a kind of metal dampers of Self-resetting bending energy-wasting.Background Technology
To be damaged building structure less under seismic loading in wind load, damper is usually set in the structure Carry out dynamic response of the control structure under wind load and seismic loading.Damper type is a lot of, and it is big to be mainly divided into four Class: metal damper, viscoelastic damper, frcition damper and viscous damper.
Wherein, metal damper becomes by its simple mechanical property, good energy consumption effect and lower cost It is mostly used in the preferred instrument for repairing old building.However, most of metal damper is disposable using instrument, such as Low Yield Point Steel damper etc., after biggish seismic loading, it is necessary to replacement be carried out to impaired damper or to its core Heart dissipative member, which carries out replacement, just can guarantee the recycling of damper.
Summary of the invention
Goal of the invention: strong the object of the present invention is to provide a kind of damping effect and no replacement is required that core dissipative member can be real The metal damper for the Self-resetting bending energy-wasting being now recycled.
Technical solution: the metal damper of Self-resetting bending energy-wasting of the present invention, including by being connected with building structural member Sliding guide that guide rod interconnecting piece and cylindrical body set on the guide rod interconnecting piece one end are composed is sheathed on sliding guide Protecting crust and the arc Wasted-energy steel plate being symmetrically set between sliding guide and protecting crust, the both ends of the arc Wasted-energy steel plate and protection Spring is equipped between shell.
Furtherly, the sum of the diameter of the thickness and cylindrical body of the symmetrically arranged arc Wasted-energy steel plate of the present invention is equal to protecting crust Inside spacing.The both ends of arc Wasted-energy steel plate, which extend, is equipped with link block, and one end of spring is fixedly connected on the link block, another End is fixedly connected on protecting crust inner sidewall.
It further says, protecting crust of the invention includes upper protecting crust disposed in parallel, lower protecting crust and ties with building The protecting crust interconnecting piece that component is connected.Cover board is equipped between upper protecting crust and the two sides of lower protecting crust.Upper protecting crust and lower anti- It is connected and fixed between protective case by tightening latch.Arc Wasted-energy steel plate is bolted to connection on protecting crust inner sidewall.
Furtherly, the threaded hole being connected with building structural member is offered on guide rod interconnecting piece of the present invention.Protecting crust The threaded hole being connected with building structural member is offered on interconnecting piece.
The utility model has the advantages that compared with prior art, remarkable advantage of the invention are as follows: the metal of the Self-resetting bending energy-wasting damps Device realizes energy consumption by the plastic bending deformation of curved metal Wasted-energy steel plate, and can be by selecting different yield strengths, difference The spring of the curved metal Wasted-energy steel plate of thickness and different-stiffness grade adjusts damper cushioning ability, and mechanical property is simply simultaneously Convenient disassembly, it is cheap, it can be realized self-regeneration, can be recycled in building structure.

Specific embodiment
Further details of the technical solution of the present invention with reference to the accompanying drawing.
The metal damper of Self-resetting bending energy-wasting of the present invention, as shown in Figure 1, including sliding guide 3, being sheathed on sliding and lead Protecting crust 4 on bar 3 and the arc Wasted-energy steel plate 5 being symmetrically set between 4 liang of insides of sliding guide 3 and protecting crust, arc Wasted-energy steel plate 5 Both ends and protecting crust 4 between be equipped with spring 6, it is preferred that the both ends of arc Wasted-energy steel plate 5 are extensible to be equipped with link block 7, spring 6 One end be fixedly connected on the link block 7, the other end is fixedly connected on 4 inner sidewall of protecting crust.
Wherein, sliding guide 3 include the guide rod interconnecting piece 1 being connected with building structural member and be set to the guide rod interconnecting piece 1 The cylindrical body 2 of one end, as shown in Figure 2.Arc Wasted-energy steel plate 5 is bolted to connection on 4 inner sidewall of protecting crust, and cylindrical body 2 are located at the middle of arc Wasted-energy steel plate 5 and are fitted with arc Wasted-energy steel plate 5, i.e., the thickness of symmetrically arranged arc Wasted-energy steel plate 5 The sum of degree and the diameter of cylindrical body 2 are equal to the inside spacing of protecting crust 4.
Protecting crust 4 includes upper protecting crust 8, lower protecting crust 9 and the protection being connected with building structural member disposed in parallel Shell interconnecting piece 10, as shown in Figure 3.It is equipped with cover board 11 between upper protecting crust 8 and the two sides of lower protecting crust 9, as shown in figure 4, on and It is connected and fixed between protecting crust 8 and lower protecting crust 9 by tightening latch 12.
The threaded hole being connected with building structural member is offered on protecting crust interconnecting piece 10.It is offered on guide rod interconnecting piece 1 The threaded hole being connected with building structural member.And accordingly, the connection between each component can utilize spiral shell by the way that threaded hole is arranged Bolt is attached.
Working principle: when being acted on by earthquake or wind load transverse horizontal force, the sliding guide 3 of the damper generates cross To displacement, the cylindrical body 2 of 3 end of sliding guide follows movement, be symmetrically disposed on arc Wasted-energy steel plate 5 inside protecting crust 4 because with Cylindrical body 2 directly contacts, thus will limit the further displacement with reduction sliding guide 3, and cylindrical body 2 will make arc consume Energy plate 5 generates deformation, achievees the effect that energy-dissipating and shock-absorbing using its plastic bending deformation.It is set to the bullet at 5 both ends of arc Wasted-energy steel plate Spring is used to be supplied to the additional stiffness of metal damper, and the deflection of arc Wasted-energy steel plate 5 is adjusted, and realizes arc Wasted-energy steel plate 5 reset after deformation occurs.
