One of type.
In order to improve the bonding strength of connector, facilitate the installation of metal energy-dissipation damper, the connector is connected by first
Fishplate bar, the second connecting plate, upper junction plate and lower connecting plate are formed by fixedly connecting;First connecting plate and the second connecting plate are in one
Clamp angle connects after being fixedly connected with building;The upper junction plate and lower connecting plate it is parallel and respectively with the first connecting plate and the
Two connecting plates are fixedly connected;The upper junction plate and lower connecting plate pass through the straightway of the second bolt and the metal dissipative cell
It is fixedly connected.
The utility model has the advantage that compared with the existing technology
1, the utility model it is rigid can to change metal energy-dissipation damper by changing core metal dissipative cell arc section curvature
Degree, to adapt to the actual demand of different operating environment.
2, the metal dissipative cell of the utility model is unyielding in small shake, can provide for building structure lateral rigid
Degree, in middle shake and big shake, hardware surrender energy consumption, reduces destruction of the geological process to main structure.
3, the utility model can be used in the aseismatic reinforcement engineering of existing structure, reduce the seismic response of existing structure,
It is set to meet current specifications requirement.
4, the utility model can directly replace the support structure in frame structure, frame-shear-wall structure and frame-tube structure
Part further decreases construction cost.
5, the utility model Energy Dissipation Mechanism is clear, and simple structure is low in cost, and replacement is convenient, using flexible, applicability
By force, it can effectively improve the anti-seismic performance of building structure, also can reduce high-rise and super high rise structure wind vibration response, while
Suitable for the rapid construction of assembled arthitecutral structure, there is good marketing application prospect.

Specific embodiment
Below in conjunction with attached drawing, a kind of metal energy-dissipation damper of the utility model is described in further detail.
As shown in Figures 1 to 5, a kind of metal energy-dissipation damper of the utility model, including connector 1 and metal energy consumption member
Part 2, connector 1 are fixedly connected with building, metal dissipative cell 2 by connector 1 and building connect, metal dissipative cell 2 by
Bolt-weld joint is constituted after local inclination in the middle part of a pair of of T section steel.Metal dissipative cell 2 divides for straightway and arc section, circle
Segmental arc both ends pass through straightway and connector 1 respectively and building connects.The straightway of metal dissipative cell 2 is equipped with multiple first
The both ends of bolt 3, above-mentioned a pair of T section steel are fixedly connected by the first bolt 3;The straightway of metal dissipative cell 2 is logical
The second bolt 4 is crossed to be fixedly connected with connector 1.Connector 1 is by the first connecting plate 5, the second connecting plate 6, upper junction plate 7 and lower company
