A multi-element blast structure

Abstract

The utility model provides a kind of multi-element anti-blast structure, including heat preservation energy-absorbing layer, the heat preservation energy-absorbing layer is fixed in the outside of protected structure;Composite anti-blast layer is arranged in the outside of heat preservation energy-absorbing layer, the composite anti-blast layer includes at least one composite anti-blast board;And fireproof insulation layer is arranged in the outside of composite anti-blast layer;Wherein, the inside of heat preservation energy-absorbing layer is provided with negative mass energy-absorbing connecting component, and the both ends of negative mass energy-absorbing connecting component are connected with protected structure and composite anti-blast layer respectively.The utility model integrates resistance shock wave, fragment, large splash multi-element damage function, and has heat preservation function simultaneously, can resist fragment penetration, large splash impact, can also attenuate shock wave by structural component plastic deformation, vibration and other forms multiple times, reduce the force finally acting on framework, and adopt assembly method, can realize quick and convenient construction and the construction of large area anti-blast structure.
