Embodiment 1
[0034] refer to Figure 1 to Figure 5 , an anti-buckling energy-dissipating tube, comprising a constraining outer tube 1, a core energy-dissipating inner tube 2 and a cover plate, wherein the core energy-dissipating inner tube 2 has a coaxial gap arranged in the constraining outer tube 1;
[0035] There are at least two rows of energy-dissipating devices on the ring of the core energy-dissipating inner tube 2, and there are at least two energy-dissipating holes 6 in each row of energy-dissipating devices; Longitudinal stiffeners are provided, and transverse stiffeners are arranged between adjacent longitudinal stiffeners;
[0036] Both ends of the constraint outer tube 1 are respectively fixedly connected to the cover plate, and both ends of the core energy-dissipating inner tube 2 protrude from the cover plate and are sealed and connected.
[0037] Further, at least two energy dissipation holes are arranged at equal intervals.
[0038] Still further, at least two transverse...
Embodiment 2
[0053] refer to Figure 1 to Figure 5 , a manufacturing process of an anti-buckling energy-dissipating tube, the manufacturing process comprising the following steps:
[0054] Step 1: Derust and degrease the outer surfaces of the constraining outer tube 1, core energy-dissipating inner tube 2, longitudinal stiffeners and transverse stiffeners, left and right cover plates, and constrain the outer tube and core energy-dissipating The cross-sections at both ends of the inner tube are polished to make the cross-section smooth and flat;
[0055] Step 2: Install energy-dissipating devices on the 2 rings of the core energy-dissipating inner pipe by means of a gas cutting process. There are at least two energy-dissipating holes 6 in each row of energy-dissipating devices;
[0056] The third step: grinding and rounding the edges and corners in the energy-dissipating hole 6 to reduce the influence of stress concentration;
[0057] Step 4: Install longitudinal stiffeners on the outer w...
