Energy dissipation and shock absorption mechanism

The invention provides an energy dissipation and shock absorption mechanism. The energy dissipation and shock absorption mechanism comprises a metal damper, a supporting or rigid wall for arranging the damper, and a connecting device connected with a structure. Two external connecting mechanisms are arranged on the metal damper; one of the external connecting mechanisms is connected with other connecting structures on a building, and the other external connecting mechanisms is connected with the building through the supporting or rigid wall; and the connection is riveting, bolt pin connection, bolt connection or welding. The energy dissipation and shock absorption mechanism comprises the metal damper, so the compression performance of the metal is used for dissipating the energy; the hysteresis curve of the energy is saturated, namely, under the condition of very small deformation (such as small vibration), the energy dissipation and shock absorption mechanism can enter plastic energy dissipation ...

Reinforcement method for concrete structure

A reinforcing method for concrete structure follows the steps as: surface treatment to the concrete structure to reveal structure sheaf and smooth and dust clean; preset super strength steel micro fiber on web texture in the same direction to form a steel micro fiber tape; spray coat on the concrete structure with a layer of high strength polymer mortar or resin mortar; stick the steel micro fiber tape to the surface; spray coat on the steel fiber tape with a layer of high strength polymer mortar or resin mortar and roll on along the fiber direction to form a close grained layer; finally spray coat protection layer to it.

Flexion energy dissipation preventing support

The invention discloses a flection and energy consumption preventing brace which comprises a core stress member, a restriction member, an isolation layer positioned between the core stress member and the restriction member, and a connecting member connected with two ends of the core stress member. The core stress member comprises two steel plates; and an elastic filling material is arranged between two steel plates. As the elastic filling material is adopted to solve the problems of the flection and energy consumption after the double steel plates are stressed, the material for the isolation material only needs to realize the separation of the double steel plate and a restriction sleeve, does not need to consider reserving a gap with certain thickness; therefore, common lipin or an organic material is applied on the surface of the double steel plates to meet the requirement, so manufacturing difficulty is greatly reduced.
