Abstract
The utility model relates to a protecting and sealing door used for civil air-defense construction, which aims to have the function of defending fragments of conventional weapons and comprises a door leaf, a steel doorframe, a sealing latch, a doorframe wall and a sealing strip. The door leaf is connected with the doorframe wall through a hinge leaf, and the sealing strip is arranged between the steel doorframe and the doorframe. The protecting and sealing door is characterized in that the door leaf is of an ultra-high strength active powder reinforced concrete structure, an armor plate is arranged behind the door leaf, and not only the side of the door leaf far from the hinge leaf but also the side of the door leaf close to the hinge leaf is provided with a sealing latch.
Description
Technical field
The utility model relates to airtight blast door, particularly ultrahigh-strength active powder concrete series airtight blast door.
Background technology
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.
Description of drawings
Fig. 1 is the assembling drawing of an embodiment of the present utility model.
Fig. 2 is the sectional view along the A-A line among Fig. 1.
Fig. 3 is the sectional view along the B-B line among Fig. 1.
The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, an embodiment of the present utility model comprises door leaf 1, steel door frame 2 with and locking 4, door frame wall 6 and weather strip 5, door leaf 1 is connected with door frame wall 6 by hinge page or leaf 3, between steel door frame 2 and door leaf 1, be provided with weather strip 5, present embodiment and the existing difference that is used for the airtight blast door of civil air defense constructions and installations are that door leaf 1 is ultrahigh-strength active powder steel concrete (RPC) structure, and steel plate 7 is set behind door leaf 1, in addition, not only locking 4 is set, also locking 4 is set in a side near the door leaf 1 that cuts with scissors page or leaf in a side away from the door leaf 1 that cuts with scissors page or leaf 3.
For the advantage to present embodiment describes, now ultrahigh-strength active powder steel concrete (RPC) structure is carried out concise and to the point introduction, ultrahigh-strength active powder steel concrete is a kind of high-strength and high ductility RPC composite material, and its main component comprises materials such as cement, steel fibre, silica flour, flyash, levigate quartz powder, water reducing agent.Present embodiment has reached following performance indications like this:
1.RPC under normal condition, compressive strength has reached 220MPa, intensity can reach 170MPa under the pumping condition.
2.RPC the anti-gamma-ray ability is 1.11 times of ordinary concrete, 60 thick ultrahigh-strength active powder concrete airtight blast door anti-gamma-ray radianting capacities are higher than 20 steel plate airtight blast doors.
3.RPC the anti-fragmentation penetration of airtight blast door ability surpasses 2 times of ordinary concretes.Can anti-conventional weapon shock wave and the compound action of its fragmentation.
4.120 the dull and stereotyped airtight blast door of thick 1320RPC can anti-100g, the 1000m/s fragmentation hits the secondary action again of back 0.4MPa nuclear blast superpressure, the dull and stereotyped airtight blast doors of 180 thick RPC can anti-100g, the 1000m/s fragmentation hits the secondary action again of back 0.6MPa nuclear blast superpressure, and 240 thick RPC arch protective doors can anti-150g, the 1000m/s fragmentation hits the secondary action again of back 7.3MPa nuclear blast superpressure.
5.80 thick 1320RPC airtight blast door can substitute existing Pyatyi 120 thick steel concrete airtight blast doors, price is high approximately by 10%, weight saving 25.5%; 120 thick 6025RPC airtight blast doors can substitute existing Pyatyi steel work airtight blast door, and price hangs down 15% approximately.
