Outer casing pipe constraint folding steel plate energy consumption support

The invention discloses an outer casing pipe constraint folding steel plate energy consumption support. The support comprises an outer casing pipe, a core barrel arranged in the outer casing pipe, end bearing plates arranged at barrel openings of the two sides of the core barrel and outer casing pipe seal plates arranged at the ends of the two side of the outer casing pipe; the end bearing plates are connected with cross-shaped node plates penetrating through the outer casing pipe seal plates, and the core barrel is formed by sequentially connecting multiple energy consumption units. The support reduces earthquake responses of buildings through the good post-yielding energy consumption capacity, is easy to manufacture and convenient to install and can be applied to structural earthquake resisting and effectively reduce earthquake disasters.
