Internal and external double-sleeve restraining folded steel plate energy-consuming support

The invention discloses an internal and external double-sleeve restraining folded steel plate energy-consuming support. The support comprises a core cylinder, an internal sleeve arranged in the core cylinder, end pressure bearing plates arranged at cylinder openings in the two sides of the core cylinder, a cross-shaped fixing plate arranged in the internal sleeve and connected with the inner sides of the end pressure bearing plates, cross-shaped plates connected to the outer sides of the end pressure bearing plates, an external sleeve arranged outside the core cylinder in a connected mode, and external sleeve sealing plates connected to the two ends of the external sleeve. The core cylinder is formed by sequentially connecting multiple energy-consuming units. The good post-yielding energy-consuming ability of the support is utilized for reducing earthquake response to buildings, and the support is easy to manufacture, convenient to install and capable of being applied to the structure seismic aspect, and effe
