Embodiment 1

[0026] Such as figure 1 As shown, the self-resetting combined disc spring U-shaped metal energy dissipation damper provided in this embodiment adopts fully assembled components, which are assembled by inner and outer sleeves, high-strength bolts, energy dissipation components and self-resetting components. The fully-assembled damper can reduce welding procedures, shorten the construction schedule, and is easy to control the quality. During use, it can be easily disassembled to replace damaged components, easy to repair and maintain, and easy to replace after an earthquake. It is cost-effective throughout its life.

[0027] In the damper of this embodiment, the outer sleeve is connected to the left end plate, the inner sleeve is connected to the right end plate, and the energy dissipation component and the self-resetting component are installed between the inner sleeve and the outer sleeve.

[0028] The energy-consuming part: the two sides of the U-shaped metal plate are respec...

Abstract

The invention discloses a fabrication type self-reset combined disc spring U metal energy dissipation damper, and belongs to the technical field of disaster prevention shock absorption. The fabrication type self-reset combined disc spring U metal energy dissipation damper is formed through parallel combination of a U metal damper and a combined disc spring, a U metal plate, high-strength bolts, anouter casing pipe, an inner casing pipe, left and right end plates and baffles are mainly included, the two sides of the U metal plate are fixed to the outer side of the inner casing pipe and the inner side of the outer casing pipe correspondingly through the high-strength bolts, the outer casing pipe is connected with the left end plate, the inner casing pipe is connected with the right end plate, one set of baffles are fixed to the outer side of the inner casing pipe, the other set of baffles are fixed to the inner side of the outer casing pipe, the combined disc spring is pre-pressed to bemounted on the outer side of the inner casing pipe in a penetrating and sleeving manner and is arranged between the two sets of baffles, the fabrication type self-reset combined disc spring U metal energy dissipation damper is applied to a lateral load resistance part in the building field of building engineering, the deforming and bearing force needs of a structure under the earthquake effect can be met, and the damper is simple in structure, definite in working mechanism, and capable of achieving stable energy dissipation performance and good self resetting performance.

Description

technical field [0001] The invention relates to the field of anti-seismic technology of civil engineering, and is an energy-dissipating and shock-absorbing component applied in the field of construction engineering. The assembled self-resetting combined disc spring U-shaped metal energy-dissipating damper has good energy-dissipating capacity and self-resetting capacity . Background technique [0002] Earthquakes can cause strong damage to structures, especially moderate and large earthquakes can lead to the collapse of structures. Just like the Tangshan earthquake and Wenchuan earthquake in China, they brought a heavy price to the people. The reason why the earthquake will cause huge damage to the structure is mainly because the existing structure does not have the ability to completely resist complex earthquakes, and the structure may suffer from an earthquake that is stronger than the fortification intensity, thus causing serious damage to it. damage damage. Although so...
