Problems solved by technology
[0002] The anti-buckling support device is an existing technology. In order to improve its performance, those skilled in the art apply origami energy-dissipating structures to the anti-buckling support device, such as CN106639462A, CN106639465A, etc., the existing problem is: limited by the Due to the mechanical characteristics of the origami energy-dissipating structure used, if the origami energy-dissipating structure is made longer, the origami energy-dissipating structure will bend, so only a straight support section can be set in the middle to reduce the length of a single-section origami energy-dissipating structure , otherwise, the restraint sleeve can only be set outside the origami energy-dissipating structure to constrain the bending of the origami energy-dissipating structure (typically such as CN106049954A, CN107083812A). A connection structure is set between the section and the origami energy-dissipating structure, resulting in a large weight of the anti-buckling support device, and the production and installation are relatively complicated. For the scheme of setting a restraint sleeve, the restraint sleeve will also lead to an increase in weight, and the fabrication , installation complex issues

The invention discloses a buckling control supporting device with a rotational symmetry section. The buckling control supporting device is composed of an energy consumption section and two end restraining sections. Connecting plates are arranged at the two ends of the energy dissipation section correspondingly, and the two end restraining sections are connected to the two connecting plates correspondingly. The energy consumption section is divided into a plurality of sections along the axial direction; each section is of a tubular rotational symmetric structure formed by four paper folding structure units; the buckling control supporting device has the beneficial technical effects that the buckling control supporting device with the rotationally symmetrical section is provided, the overall length of the device can have the energy dissipation capacity under the condition that a constraint sleeve is not used, and the device is light in dead weight and relatively easy to manufacture and install.
