Sound-proof and explosion-proof civil defense door
The invention discloses a sound-proof and explosion-proof civil defense door which comprises a door frame, a civil defense door body, concrete arranged in the civil defense door body, a reinforcing device arranged on the door frame, an opening and closing device arranged on the civil defense door body and sound-proof sealing devices arranged on the door frame and the civil defense door body. The concrete comprises the following components in parts by weight: 330 parts of cement, 63 parts of fly ash, 15 parts of a polycarboxylate superplasticizer, 0.2 part of calcium gluconate, 155 parts of water, 13 parts of perfluoropolyether and 9 parts of lauramidohydroxysulfobetaine. The compactness of the hardened concrete is improved, the hardening strength is higher, and the overall impact-resistantprotection and sound-proof effects of the civil defense door are good.
本发明公开了一种隔音防爆式人防门，包门框、人防门本体、设于人防门本体内的混凝土、设于门框上的加固装置、设于人防门本体上的开关装置、设于门框和人防门本体上的隔音密封装置；所述混凝土按重量份数计包括水泥330份、粉煤灰63份、聚羧酸减水剂15份、葡萄糖酸钙0.2份、水155份、全氟聚醚13份、月桂酰胺羟磺甜菜碱9份；本发明提高混凝土硬化后致密性和具有更强的硬化强度，人防门整体抗冲击防护和隔音效果好。
