Embodiment Construction
[0043] The specific implementation of the self-resetting metal bellows damping appliance with position-limiting function of the present invention will be described below in conjunction with the accompanying drawings:
[0044] Such as figure 1 As shown, a self-resetting metal bellows damper structure with a position-limiting function includes an inner tube 1, a metal bellows 2, an outer tube 3, a connecting steel plate 4, a free end plate 5, a cross steel plate 6, and a prestressed tendon 7 , Anchor 8, limit arc end plate 9, arc strike plate 10.
[0045] The inner pipe 1 is passed through the right connecting steel plate 4, and the four arc-shaped end plates 9 at the right end of the inner pipe are welded to four limit arc-shaped end plates. The arc strike plate 10 connected to the steel plate 4 on the right side is welded and connected with the inner pipe. Insert the metal bellows 2 from the left side of the inner tube 1, put the metal bellows 2 outside the inner tube 1, and...

The invention discloses a self-resetting metal corrugated pipe damper with a limiting function. The self-resetting metal corrugated pipe damper comprises an inner pipe, a metal corrugated pipe, an outer pipe, a connecting steel plate, a free end plate, a cross steel plate, a prestressed rib, an anchorage device, a limiting arc-shaped end plate and arc striking plates. The inner pipe is a round steel pipe, the end part of the inner pipe is slotted to become a four-section arc plate so as to penetrate through the connecting steel plate, four limiting arc end plates are welded to the end part of the four-section arc plate of the inner pipe, the connecting steel plate is a circular steel plate, the four arc striking plates are welded on the inner side of the connecting steel plate and are used for being in welding connection with the metal corrugated pipe, the inner pipe and the outer pipe respectively, eight pore passages are reserved in the cross steel plate so as to be connected into the structure as a connector, the other end is in welding connection with the connecting steel plate, and the arc striking plates on the connecting steel plate are respectively welded with the metal corrugated pipe, the inner pipe and the outer pipe. The self-resetting metal corrugated pipe damper has the characteristics of high energy dissipation efficiency, stable performance and uniform stress, provides a limiting function through a free end plate, and ensures the stability of the structure.
Description
technical field [0001] The invention belongs to the technical field of energy dissipation and shock absorption of engineering structures, and in particular relates to a self-resetting metal bellows damper with a position limiting function. Background technique [0002] In recent years, in order to ensure the safety and applicability of engineering structures, engineering structure isolation, shock absorption and vibration control technologies have been continuously developed. Among them, metal dampers have been more and more widely used in the field of energy dissipation and shock absorption due to their simple structure, convenient manufacture, low cost, superior energy dissipation performance, and easy replacement. [0003] The metal damper dissipates part of the energy of the structural vibration through the yield hysteresis energy dissipation of the metal, thereby reducing the structural reflection, and concentrating the shock damage on the replaceable structural compone...
