Abstract

The invention discloses an anti-impact composite protective door for civil air defense engineering, and belongs to the field of civil air defense engineering equipment. The anti-impact composite protective door includes a door body and a door frame, the door body includes an outer layer arch-shaped plate and an inner layer flat plate connected to the inner wall of the outer layer arch-shaped plate, a cavity is formed between the inner layer flat plate and the outer layer arch-shaped plate, a filling layer is arranged in the cavity, the filling layer includes a honeycomb skeleton and a fillingmaterial filling the honeycomb skeleton, the filling material is one or more of sand, concrete and polyurethane, and the outer layer arch-shaped plate and the inner layer flat plate are made of steelor glass fiber reinforced plastic composite materials. The anti-impact composite protective door has a simple structure and reasonable design, and the resistance to shock waves of the protective doorcan be effectively improved.

Description

technical field [0001] The invention relates to the field of civil air defense engineering equipment, in particular to an impact-resistant composite protective door for civil air defense engineering. Background technique [0002] The mouth of the protection project is the weak link of the project, and it is also the key strike point. The underground protection project bears the important responsibility of protecting the safety of internal personnel and equipment. Therefore, the protective door, as the most important protective equipment at the mouth, plays an important role in ensuring the overall safety of the civil air defense project. Therefore, it has always been the key content of protective engineering research. [0003] Most of the existing protective doors are made of reinforced concrete, and the door body usually adopts a flat door or an arched door. Because the resistance level of the protective door is usually very high, the door body of the reinforced concrete s...
