Description

Buffering and energy-absorbing structure for steel antiknock door for petrochemical industry Technical Field The utility model relates to the technical field of antiknock doors, in particular to a buffering and energy-absorbing structure of a steel antiknock door for petrochemical industry. Background The steel antiknock door is a special door made of steel materials and has high strength and good impact resistance. The structure is firm, and special hardware fittings and sealing materials are provided, so that shock waves and fragments generated by explosion can be effectively resisted. The anti-explosion protective barrier is often applied to places with explosion risks such as petrochemical industry, military industry and nuclear power, can ensure personnel safety and facility integrity, and provides a reliable safety protective barrier for key areas. The steel anti-explosion door is mainly used for blocking explosion impact, and the current steel anti-explosion door is insufficient in buffering and energy absorbing performance, concrete, perlite and the like are mainly filled in the steel door, the strength of the anti-explosion door is increased by using the filler, the explosion impact force is not conveniently and effectively absorbed, and deformation and damage of the steel anti-explosion door are easily caused. In view of this, we propose a cushioning and energy absorbing structure for steel antiknock doors for petrochemical industry.
