The application discloses a layered vertical energy dissipation support, and relates to the technical field of civil engineering structures, which comprises a lower steel cylinder assembly, an upper steel cylinder assembly and a middle energy dissipation assembly; the lower steel cylinder assembly is filled with concrete; the upper steel cylinder of the upper steel cylinder assembly is coaxially arranged with the lower steel cylinder and is located above the lower steel cylinder; the lower part of the upper steel cylinder is located outside the upper part of the lower steel cylinder, and an energy dissipation gap is formed between the lower part of the upper steel cylinder and the upper part of the lower steel cylinder; the middle energy dissipation assembly is arranged in the energy dissipation gap and is composed of a plurality of energy dissipation steel cylinders and a plurality of polyurethane layers alternately. The application provides flexible restoring force and damping through the polyurethane material, so that the support can effectively adapt to vertical tensile and compressive deformation, and the energy dissipation performance of the support is significantly improved through the shear deformation of the polyurethane material, and the shock absorption and vibration control performance of the support is improved. The support structure is reliable and is suitable for parts in structures that need to bear vertical loads and have shock absorption requirements.

This invention discloses an intelligent production line for prefabricated steel structure wall panel frames, divided into a material processing area, a logical sorting area, and an assembly and forming area according to the process flow. The material processing area includes a movable and changeable uncoiling and feeding mechanism and a keel machine. The logical sorting area is equipped with a sorting mechanism and a sorting controller, including a pushing unit and a flipping unit. The assembly and forming area includes an assembly and dragging mechanism, a conveyor line, and a nailing machine. The core of the invention lies in the sorting controller's logical comparison of the preset installation position parameters of the keel truss to be processed in the wall drawings—including the lowest point height value β and the length value λ—with the wall height boundary line h and the length threshold α. This comparison then controls the sorting execution module to adaptively sort the keel truss to the upward flipping area, the downward flipping area, or the short material area. This invention achieves adaptive intelligent sorting and attitude pre-adjustment of the keel truss based on spatial position parameters, significantly improving the flexibility, assembly efficiency, and quality stability of prefabricated steel structure frame production.
