Abstract
The invention creatively relates to a fireproof device for external heat insulation materials for a high rise building curtail wall. The fireproof device comprises an external decorative material of the curtain wall, a heat insulation layer and a building structure wall, wherein a plurality of airflow barrier sheets are arranged between the external decorative material of the curtain wall and the heat insulation layer; every upper and lower airflow barrier sheets form enclosed space; the airflow barrier sheets are movable fireproof sheets which are placed flatwise or slantwise; a longitudinal main gas pipeline is arranged between the external decorative material of the curtain wall and the heat insulation layer and penetrates through each airflow barrier sheet; a transverse branch gas pipeline is arranged in each enclosed space and is communicated with the main gas pipeline; and control valves and nozzles are arranged on the branch gas pipelines respectively. The device has the following beneficial effects: the airflow barrier sheets are utilized to divide the hollow structures inside the materials for the high rise building curtail wall into a plurality of enclosed space, thus avoiding the stack effect during fire, and meanwhile, the flame retardant gases are jetted into the corresponding enclosed space via the branch gas pipelines, thus effectively reducing the combustion and spread speeds of the heat insulation materials or extinguishing the flames.
Description
Technical field
The invention relates to a kind of fireproof device for external heat insulation materials for high rise building curtail, for blocking spreading fast of curtain wall for high rise building heat insulating material for external burning.
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, feudal dynasty Wan Xin mansion, Shenyang in 2011 fire etc.Building curtain wall heat insulating material for external and Building Curtain Wall Structures provide 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 7,000,000 square metres of left and right at present, and market prospects are still good.Both at home and abroad this is too controversial for the building bound pair, and wherein country's explicit stipulation such as Japanese, German bans use of.Reason is the hollow structure of curtain wall for high rise building material internal vertical direction, will be as a towering chimney when breaking out of fire, become the important channel of the fire spreads quickly, and usually wait complete 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, or adopt which type of security against fire technology to guarantee fire safety, is one of security against fire technical barrier in the urgent need to address.
Summary of the invention
The technical problem that the invention will solve is to provide a kind of fireproof device for external heat insulation materials for high rise building curtail, this device utilizes the air-flow barrier plate hollow structure of curtain wall for high rise building material internal to be divided into to the space of many sealings, stack effect while having avoided fire, by the gas transmission branch pipe(tube), corresponding enclosure space is sprayed to fire-retardant gas simultaneously, thereby effectively reduce heat insulating material burning rate of propagation or flame is suffocated.
For overcoming the above problems, concrete technical scheme of the present invention is as follows: a kind of fireproof device for external heat insulation materials for high rise building curtail, 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, every upper and lower two air-flow barrier plates form an enclosure space, and the air-flow barrier plate is to keep flat or movable fire prevention thin plate that tilting is laid; Be provided with vertical gas transmission main pipeline between curtain wall decorative material and insulation layer, the gas transmission main pipeline is through every layer of air-flow barrier plate, be provided with horizontal gas transmission branch pipe(tube) and communicate with the gas transmission main pipeline respectively in each enclosure space, be respectively equipped with by-pass valve control and nozzle on the gas transmission branch pipe(tube).
Be provided with flame temperature perception air bag in described enclosure space, be filled with fire-retardant gas in 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 by wire with external control system and be connected.
Described gas transmission main pipeline is arranged on the inside that gas transmission main pipeline between curtain wall decorative material and insulation layer replaces with the building structure wall, by the gas transmission branch pipe(tube), through building structure wall and insulation layer, is extend into respectively in each enclosure space.
This fireproof device for external heat insulation materials for high rise building curtail adopts the air-flow barrier plate can effectively prevent spreading of the intensity of a fire, prevent stack effect, the hollow structure of curtain wall for high rise building material internal is divided into to many enclosure spaces simultaneously, valve and the nozzle communicated with the gas transmission main pipeline is set in each enclosure space, for controlling the fire-retardant gas of ejection, reduce the oxygen concentration of enclosure space, reduce the burning velocity of insulation layer.
Be provided with the air bag that fills fire-retardant gas in each enclosure space, be used for perception flame high temperature action, air bag will have or not pressure signal to be transferred to external control circuit by the pressure meter connected, with guarantee air bag on fire broken by combustion after, the gauge hand back to zero, the wire short circuit be attached thereto, be transferred to control circuit by this signal, control system is opened by-pass valve control, by nozzle, to corresponding enclosure space, fills fire-retardant gas.
The gas transmission main pipeline also can be arranged in the building body, and the gas transmission branch pipe(tube) be attached thereto during fire is to the fire-retardant gas of enclosure space delivered inside.
