Abstract
The utility model discloses a reinforced concrete protection air-tight door, which comprises a door frame and a door leaf, wherein the door leaf comprises an outer layer steel plate and an inner layer steel plate; the inner surface of the outer layer steel plate is provided with a first heat insulating layer; the inner surface of the inner layer steel plate is provided with a second heat insulating layer; and a reinforced concrete layer is formed between the first heat insulating layer and the second heat insulating layer. Through the way, the reinforced concrete protection air-tight door has high strength, and can be used for blocking explosive shock waves; and moreover, high heat-insulating performance is realized.
Description
Technical field
The utility model relates to the civil air defense constructions and installations technical field, particularly relates to a kind of steel concrete airtight blast door.
Background technology
Civil air defense projects are called for short civil air defense constructions and installations, refer to for ensure wartime personnel with the underground protective structure that goods and materials are sheltered, people's air defence commander, medical aid build separately, and the combined ground building wartime of building can be used for antiaircraft basement.The steel concrete airtight blast door is a kind of safety protective door commonly used in the underground civil air defense constructions and installations, is used for stopping explosion wave etc., and existing steel concrete airtight blast door exists insufficient strength, the bad shortcoming of effect of heat insulation.
