Abstract

The utility model discloses an emergency refuge house device of fire hazards. An emergency refuge house which can become an enclosed space needs to be arranged in buildings, and metal water containers which are connected and communicated to each other are arranged on each concrete peripheral wall and the interlayer of the door body. When the fire occurs, the emergency refuge house utilizes the circulation of the water liquid in the water chambers which are on the concrete peripheral walls and the interlayer of the door body to form a heat-insulating, airtight, water-cooling space to keep the high temperature and the smoke of the fire resource out of the emergency refuge house, keeping the people in the emergency refuge house safe.

Description

Fire act of rescue chamber device

Affiliated technical field

The utility model relates to a kind of fire act of rescue chamber device, refers to that especially a kind of sealed chamber structure with fire-proof function establishes.

Background technology

Press, the reason that fire is fearful mainly is that the result that material combustion produces in the fire process obviously threatens personnel's life, no matter be the personnel of and neighboring region interior to fire burning system, but its relative seriousness is decided according to each fire situation.Fire is as follows for the general division of the effect of safety of human life:

(1) oxygen depletion

General human, it is comfortable movable to be used under 21% oxygen concentration of atmosphere.When oxygen concentration is lower than 17%, muscle function can go down, and this is the air hunger phenomenon.When 10%～14% oxygen concentration, the people but manifests false judgment power still consciously, and itself does not discover.And when 6～8% oxygen concentrations, death by suffocation will take place in breath stopped in 6～8 minutes.Excited and the activity that is caused by fire often increases the demand of human body to oxygen, so in fact when oxygen concentration is still high, promptly may occur the not enough symptom of oxygen.Can the oxygen concentration lower bound of common people survival be 10%, yet arrive this degree and how soon arrive, and is different according to diverse location in each fire and the burning system, is that volume and ventilative speed influence because this concentration is subjected to combustible concentration, burning velocity, burning.

(2) flame

Burn may cause because of the direct contact and the heat radiation of flame.Because the bright few and combustible substance disengaging of flame, so normal the generation directly of personnel in the neighboring region threatened, this point is different with burning gases and cigarette.Skin is as if maintaining more than 66 ℃ of the temperature (150) or being subjected to radiant heat 3W/cm ²More than, only must can cause burn in 1 second, so flame temperature and radiant heat thereof may cause immediately or be fatal afterwards.

(3) heat

Heat in the burning system and the personnel of neighboring region all have danger.No matter any oxygen expenditure of aunt or toxic effect by the hot air and the gas of flame generation, also can cause burn, heat collapse, dehydration and respiratory tract obturation (oedema).The horizontal temperature of breathing of the existence limit is about 131 ℃ (300 °F); But indoor air temperature still can be survived blink during up to 140 ℃.Breathe level height again, upwards count from the floor and generally be about 1.5 meters distances more than (5 Foot), when children occupy remarkable ratio among the personnel of room sometimes, then adopt 1.2 meters (4 Foot) level height on the Safety Design.For breathing, the temperature that surpasses 66 ℃ (150) just is difficult to stand, and it is slow that this temperature field may make the fire fighter rescue and indoor occupant is escaped.

(4) poisonous gas

The thermal decomposition and the combustion products composition kind of general macromolecular material are numerous and diverse, reach more than hundred kinds sometimes, and only be wherein a part of yet Human Physiology is had the gas product of concrete poisonous effect.The toxic composition of these gases can be divided three classes basically:

1. asphyxiating or stupor property composition.

2. to sense organ or respiratory apparatus composition excitatory.

3. other unusual toxic composition.

Though learn from the fire fatality statistics, most of victim causes death because of sucking unwanted combustion gases such as carbon monoxide, should not too emphasize sometimes, and be identical because there is not a fire condition.A part of in addition fire test also shows under many situations before arbitrary toxic gas no show lethasl concentration still, minimum survival oxygen concentration or shout the flat temperature of suction most and promptly arrive in advance.

(5) cigarette

Cigarette be material when burning or thermal decomposition take place institute discharge and disseminate solid-state in air, liquid particulate and gas.Cigarette is important product in the fire combustion process, because visibility is the building that can the refugee escape from breaking out of fire, and the fire fighter's influence factor that can find out fire, stamp out a fire.Cigarette can encourage alarmed situation, because it has sight line to cover and stimulating effect.In many situations, cigarette often makes us being difficult to TL than more Zao the reaching of temperature on the means of escape.

Traditional rooms of buildings, owing to material and bubble-tight reason, when meeting with fire, can't effectively completely cut off the threat that produces in the above-mentioned various combustion process to personnel's life, advanced administrative staff that can only be passive evacuates and fire extinguishing, tends to cause great casualties.

The utility model content

The utility model main purpose is to provide a kind of fire act of rescue chamber device; it mainly is the act of rescue chamber that in building or open-air building, is preset with confined space; when breaking out of fire,, and can protect the safety of personnel's life with the high temperature of isolated burning things which may cause a fire disaster, smog etc.

The utility model adopts following structure to realize above-mentioned purpose: a kind of fire act of rescue chamber device, it mainly is preset with the act of rescue chamber that can be confined space in building, wherein in each concrete perisporium and door interlayer body of this act of rescue chamber, be provided with the metal water container that interconnects perforation.

Each water receptacle in described concrete perisporium and the door interlayer body is provided with one or more hole for water sprayings to this outdoor sprinkling.Described perisporium is the fire prevention material.

In addition, be provided with automatic emergency light, water receptacle Water supply switch valve, oxygen supply in this act of rescue chamber.

This refuge chamber also can be provided with sanitary bath equipment.

Each metal water jar of described connection is located at the superficies of suitable chamber in the building, and has the hole for water spraying of outside sprinkling.

Adopt the utility model structure; when fire takes place; this act of rescue chamber can utilize the water liquid circulation of water receptacle in the interlayer of concrete perisporium and door body and form heat insulation airtight, a water-cooled space; and high temperature, the smog of burning things which may cause a fire disaster is blocked in outside the act of rescue chamber, with the take refuge life security of indoor occupant of protection.Wherein, each water receptacle in concrete perisporium and the door interlayer body is provided with some to outdoor hole for water spraying, except that the water liquid recycle stream that helps water receptacle is logical and be easy to cool off perisporium and keep the interior temperature, also have to make the effect of eliminating and reduce temperature near flame around this refuge chamber.Simultaneously, be provided with automatic emergency light, water receptacle Water supply switch valve, oxygen supply in this act of rescue chamber, help act of rescue use in the fire.
