Metallic damper can pass through the most seismic energy of the inelastic deformation of ductile metal dissipation.Use gold
Earthquake can be concentrated on scheduled and replaceable structure member by belonging to surrender damper, to avoid causing not main structure
Recoverable damage.Principle is surrendered according to deformation, flexure type metal damper and axial deformation type metallic damper are the most
It is common.Existing metallic damper can effectively consume energy, but that there is also steel utilization ratios is low, and steel consumption is big；Manufacture
The problems such as difficulty is big, and maintenance is at high cost.
Summary of the invention
In order to make up the defect of the prior art, the invention proposes a kind of novel steel bar metallic dampers, by several
A parallel connected steel bar realizes energy consumption by plane inner bending surrender, and steel bar uses equicohesive section form, material
Utilization rate is high.Meanwhile steel bar is readily replaceable, and it is few using steel, more have practical value.Structure configuration is simple, manufacture and safeguard at
This is more relatively low than other metal dampers.
To realize the above-mentioned technical purpose, the technical solution of the invention patent is that the present invention is that a kind of novel steel bar metal is in the wrong
Take damper, including three steel bar, interior case and outer container parts.Outer container and interior case are solid by high-strength bolt and arrangement holding portion
Knot.Interior case is hinged by high-strength bolt and steel bar with outer container.
It is also resided in, and internal and outer container is rigid.
It is also resided in, and steel bar is designed using equicohesive section, and steel bar is divided into three sections, the edge both ends Liang Duan aperture, with
Interior case is hinged, and interlude edge is by interior case limiting displacement.
It is also resided in, and is arranged sliding slot on outer container, and steel bar is allowed to laterally move in stress, with realize steel bar without axle power
State generates the plastic deformation of material by bending substantially, to improve steel utilization ratio.
It is also resided in, and steel bar metallic damper allows designer by the steel bar of addition different number, to obtain
Different damping forces and deformability.
Compared with prior art, this patent beneficial effect is:
The invention patent is designed using equicohesive section, realizes total cross-section surrender, the surrender of material is made full use of to consume energy
Ability；It is few using steel, it is readily replaceable after steel bar damage；It can be by adding the steel bar of different number to obtain different dampings
Power and deformability；The invention patent has the advantages that batch production production is simple, easy for installation, maintenance cost is low etc., has higher
Practical value and economic benefit.
The invention patent is described further with reference to the accompanying drawing.

Specific implementation method
Below to the further explanation of the invention patent technology contents, but not to the limit of the invention patent substantive content
System.
Fig. 1 is the structural schematic diagram of the novel steel bar metallic damper of the embodiment of the present invention, and Fig. 2 is that the present invention is implemented
The structural schematic diagram of the novel steel bar metallic damper steel bar of example, Fig. 3 are that the novel steel bar metal of the embodiment of the present invention is bent
Take the side elevational view of damper；Fig. 4 is the structural schematic diagram of the novel steel bar metallic damper inner box of the embodiment of the present invention；
Fig. 5 is the structural schematic diagram of the novel steel bar metallic damper outer box of the embodiment of the present invention.As shown in Fig. 1,2,3,4,5,
Novel steel bar metallic damper, including interior case 1, outer container 2, interior case 1, outer container 2 and structural support consolidate.Outer container 1 and interior case 2
It is rigid.Steel bar 3 is divided into three sections, including one section 10 of steel bar energy consumption, two section 11 of steel bar energy consumption, three section 12 of steel bar energy consumption, steel
One section 10 of item energy consumption and steel bar three sections of 12 two sections of edges both ends apertures of energy consumption, hinged by high-strength bolt 4 with interior case 1, steel bar consumes
Two section of 11 edge of energy is by 2 limiting displacement of outer container.Steel bar 3 is connect with outer container 2 by high-strength bolt 5, and screw rod can be horizontal in sliding slot 6
To movement, i.e. permission steel bar is laterally moved in stress, with realize steel bar without axle power state.When an earthquake occurs, frame
Structure generates relative storey displacement, supporting member axial tension, in steel bar 3 steel bar consume energy one section 10, steel bar consumes energy two section 11 and steel bar
Energy consumption generates the changing of the relative positions under the action of interior case 1 and outer container 2 for three section 12, and steel bar 3 is caused to deform, to realize that metal yield consumes energy.
Steel bar metallic damper of the present invention allows to add the steel bar 3 of different number, with obtain different damping force and
Deformability using 20 steel bars 3 of setting in this example, while can be generated not by increasing or decreasing the thickness of steel bar 3
Same damping force.
According to theory analysis, the invention patent devises best geometry to steel bar 3, to realize wanting for equal strength section
It asks, prevents strain from concentrating on the Part portions of component.Steel bar consumes energy one section 10 to consume energy three section 12 with steel bar to be designed for variable cross-section, wide
Spending version is linear, length 30mm, end portion width 6.5mm；Steel bar consumes energy two section 11 for cross-section section, and length is
80mm, width 15mm.The diameter of bolt of high-strength bolt 4,5 is 7.5mm, and the screw rod of bolt is all made of high strength steel production.
The surface of prepared screw-bolt hole 9 and sliding slot 6 should carry out smooth treatment.
Steel bar 3 uses Q235 steel, with a thickness of 8mm；Interior case 1 and outer container 2 are all made of the Aldecor of Q460, thick
Degree is respectively 20mm and 12mm.
