Background technology
Several fire of high-rise building in recent years all cause by external-wall heat-insulation material, as: Beijing Chinese Central Television (CCTV) new address fire in 2009, teacher apartment, Shanghai in 2010 fire, prosperous mansion fire of Shenyang feudal dynasties ten thousand in 2011 etc.Building curtain wall heat insulating material for external and Building Curtain Wall Structures provide the important channel for these several fire rapid spreads.Modern high-rise building adopts building curtain wall to make exterior decoration mostly, and the building area of the annual building curtain wall of China reaches about 7,000,000 square metres at present, and market prospects are still good.This is too controversial to build bound pair both at home and abroad, and wherein countries such as Japan, Germany expressly provide and ban use of.Reason is the hollow structure of curtain wall for high rise building material internal vertical direction; When breaking out of fire, will look like a towering chimney; Become the important channel of The fire spreads quickly; And usually wait and finish less than evacuating personnel, curtain wall drops downwards with regard to reaching fire endurance, has a strong impact on crowd's safety.Therefore, can building curtain wall improve, and perhaps adopts which type of security against fire technology to guarantee fire safety, is one of security against fire technical barrier that presses for solution.
Summary of the invention
The technical problem that the invention will solve provides a kind of curtain wall for high rise building heat insulating material for external firebreak device; This device utilizes the air-flow barrier plate hollow structure of curtain wall for high rise building material internal to be divided into the space of many sealings; Stack effect when having avoided fire; Through the gas transmission branch pipe(tube) corresponding enclosure space is sprayed fire-retardant gas simultaneously, thereby effectively reduce heat insulating material burning rate of propagation or flame is suffocated.
For overcoming the above problems; The concrete technical scheme of the utility model is following: a kind of curtain wall for high rise building heat insulating material for external firebreak device; Comprise curtain wall decorative material, insulation layer and building structure wall; Several air-flow barrier plates are set between curtain wall decorative material and insulation layer, and every two air-flow barrier plates are up and down formed an enclosure space, and the air-flow barrier plate is to keep flat or movable fire prevention thin plate that tilting is laid; Between curtain wall decorative material and insulation layer, be provided with vertical gas transmission trunk line; The gas transmission trunk line passes every layer of air-flow barrier plate; In each enclosure space, be provided with horizontal gas transmission branch pipe(tube) and communicate with the gas transmission trunk line respectively, on the gas transmission branch pipe(tube), be respectively equipped with by-pass valve control and nozzle.
Be provided with flame temperature perception air bag in the described enclosure space; Be filled with fire-retardant gas in the flame temperature perception air bag; This gas is connected with pressure meter, and pressure meter has pressure and the automatic recurring structure of no signal arranged and carry out circuit through lead with external control system and be connected.
Described gas transmission trunk line is arranged on the inside that gas transmission trunk line between curtain wall decorative material and the insulation layer replaces with the building structure wall, passes building structure wall and insulation layer by the gas transmission branch pipe(tube), extend into respectively in each enclosure space.
This curtain wall for high rise building heat insulating material for external firebreak device adopts the air-flow barrier plate can effectively prevent spreading of the intensity of a fire; Prevent stack effect; Hollow structure with the curtain wall for high rise building material internal is divided into many enclosure spaces simultaneously, and valve and the nozzle that communicates with the gas transmission trunk line is set in each enclosure space, is used for the fire-retardant gas of control ejection; Reduce the oxygen concentration of enclosure space, reduce the burning velocity of insulation layer.
In each enclosure space, be provided with the air bag that fills fire-retardant gas, be used for perception flame high temperature action, air bag will have or not pressure signal to be transferred to external control circuit through the pressure meter that connects; With guarantee air bag on fire by combustion broken after; Gauge hand returns zero, and the lead short circuit that is attached thereto is transferred to control circuit with this signal; The control system opens by-pass valve control, fills fire-retardant gas through nozzle to corresponding enclosure space.
The gas transmission trunk line also can be arranged in the building body, and the gas transmission branch pipe(tube) that is attached thereto during fire is to the fire-retardant gas of enclosure space delivered inside.

Fig. 2 is curtain wall for high rise building heat insulating material for external firebreak device embodiment two structural representations.
The specific embodiment
Embodiment one:
As shown in Figure 1; A kind of curtain wall for high rise building heat insulating material for external firebreak device comprises curtain wall decorative material 1, insulation layer 3 and building structure wall 4, and several air-flow barrier plates 2 are set between curtain wall decorative material 1 and insulation layer 3; The distance of each air-flow barrier plate 2 and total quantity can be decided according to the height of building building body; Every two air-flow barrier plates 2 are up and down formed an enclosure space 6, and air-flow barrier plate 2 is the movable fire prevention thin plate that keeps flat or tilting is laid, and its angle of inclination is less than 90 ° more than or equal to 0 °; Air-flow barrier plate 2 can be regulated setting angle according to the distance between curtain wall decorative material 1 and the insulation layer 3 like this, makes installation more flexible.Between curtain wall decorative material 1 and insulation layer 3, be provided with vertical gas transmission trunk line 5; Gas transmission trunk line 5 passes every layer of air-flow barrier plate 2; In each enclosure space 6, be provided with horizontal gas transmission branch pipe(tube) 11 and communicate with gas transmission trunk line 5 respectively, on gas transmission branch pipe(tube) 11, be respectively equipped with by-pass valve control 8 and nozzle 7.
