Abstract

The invention discloses a novel fabricated transformation type anti-buckling energy dissipation support and a manufacturing technology. The anti-buckling energy dissipation support comprises a main core material, an assistant core material, a main structure, a limiting unit located on the peripherals of the main core material and the assistant core material, connecting plates and connecting boltsused for connecting the main core material and the assistant material, structural connecting plates and structural connecting bolts used for connecting a support main structure, a non-bond material and a compression material. The limiting unit comprises a casing pipe, covering plates and a grouting material. The main core material and the assistant core material are located in the casing pipe; installation covering plates at two ends of the casing pipe form a sealed cavity, and the grouting material is arranged in the sealed cavity in a filling mode; the main structure is located among four stretching structural connecting plates, and the four structural connecting plates and the main structure are fixed by the structural connecting bolts; the main core material and the assistant core material are connected by the connecting bolts; and the main core material, the assistant core material and the main structure are connected by the structural connecting bolts. The anti-buckling energy dissipation support has the advantages of being good in stretchability, free of residual stress and residual deformation to support core bearing components, and good in durability and anti-seismic property.

Description

Technical field [0001] The invention relates to the technical field of bridge engineering structure and construction engineering vibration reduction technology, in particular to a novel assembly conversion type anti-buckling energy-consuming support and manufacturing process. Background technique [0002] The anti-buckling energy dissipation support generally mainly consists of an internal core force unit and a peripheral constraint unit. When the structure using the anti-buckling energy dissipation support is subjected to dynamic loads such as earthquakes, the energy dissipation effect is achieved through the hysteresis of the core material to achieve The role of the structure "fuse". [0003] At present, the anti-buckling energy dissipation supports in the domestic market are mainly divided into two categories according to the restraint method: ① pure steel anti-buckling energy dissipation supports; ② steel-concrete anti-buckling energy dissipation supports. In most projects, en...
