In order to prevent that nuclear explosive shock wave and conventional weapon shock wave and its fragmentation from entering civil air defense constructions and installations, improve the survival ability of civil air defense constructions and installations, satisfy the instructions for use of civil air defense constructions and installations, need airtight blast door to be set at the civil air defense constructions and installations oral area.The airtight blast door that is used for civil air defense constructions and installations of current production, what adopt mostly is ordinary reinforced concrete and steel work airtight blast door, this class door volume is big, heaviness, processing, debugging and installation are all complicated, and working service management at ordinary times is also inconvenient.The steel work airtight blast door is in civil air defense constructions and installations cool place, humidity, under the environment of ventilation condition difference, and easy general corrosion during the southern area plum rain season particularly, this influences the functional requirement that its long preservation, wartime are used.While is along with the variation of international situation, the status of conventional weapon in modern war improves constantly, more and more be subject to people's attention, the Gulf War, Kosovo War, Afghan War are exactly typical example, a large amount of uses of conventional weapons such as precision-guided bomb, cruise missile, JDAM and air-to-ground guided missile, modern war has changed the high-tech conventional war under the nuclear threat condition into.But the airtight blast door that uses is only considered anti-nuclear explosive shock wave at present, anti-conventional weapon only relies on from designing means such as changing the oral area form and reaches, so current airtight blast door can not satisfy new service requirement fully, the content that existing airtight blast door exists following deficiency and is further improved:

1. airtight blast door is to act as the master with anti-nuclear explosive shock wave in the design in the past, therefore at present do not consider fragmentation penetration and shock wave compound action, the airtight blast door that designs with the nuclear explosion load obviously can not adapt to the needs that preventive works are built in the local conventional war of high-tech under the nuclear threat condition;

2. existing airtight blast door need rely on from designing the requirement that the method that changes the oral area form satisfies anti-conventional weapon fragmentation, and there is certain limitation in this method cost height in practice;

3. though existing ordinary reinforced concrete airtight blast door cost is low, fragility is big, destroys seriously the strike of the very difficult ripple that withstands shocks again after fragmentation hits.

Though 4. existing steel work airtight blast door good toughness, the cost height, and also its fire prevention, anti-early nuclear radiation, anti-corrosion capability are poor.

The utility model content

The purpose of this utility model provides a kind of novel airtight blast door, and this airtight blast door possesses the function of anti-conventional weapon fragmentation.

In order to achieve the above object, the airtight blast door that is used for civil air defense constructions and installations of the present utility model comprise door leaf, steel door frame with and locking, door frame wall and weather strip, door leaf is connected with door frame wall by the hinge page or leaf, between steel door frame and door leaf, be provided with weather strip, be characterized in that door leaf is the ultrahigh-strength active powder reinforced concrete structure, and steel plate is set behind door leaf, not only locking is set, also locking is set in a side near the door leaf that cuts with scissors page or leaf in a side away from the door leaf that cuts with scissors page or leaf.

The utlity model has following advantage:

The compound action that 1, can resist nuclear explosive shock wave, conventional weapon shock wave and fragmentation penetration satisfies the needs that preventive works are built in the local conventional war of high-tech under the nuclear threat condition;

2, the scope of application wider than existing airtight blast door reduces object of construction production changing the pro forma input of oral area, reduces construction costs;

3, than existing steel work airtight blast door better anti-early nuclear radiation, anti-corrosion capability are arranged.
