Abstract
The utility model discloses a fire-resistant and heat-insulating glass door and window or glass separating curtain wall system with the fire-resistant time limit of over three hours. The fire-resistant and heat-insulating glass door and window or glass separating curtain wall system comprises fire-resistant glass and a fire-resistant steel frame used for clamping the fire-resistant glass. A spraying device is arranged on the upper portion of the fire-resistant steel frame. The spraying device is connected with a fire control water source of a building and a valve of the spraying device is controlled by a temperature sensor. When a fire disaster occurs indoors and indoor temperature rises to a temperature set value of the temperature sensor, the temperature sensor is triggered and the spraying valve is opened automatically. Water of a fan shape is sprayed on a fired face of the fire-resistant glass. The C-type monolithic fire-resistant glass is used and the manufacturing cost of the C-type monolithic fire-resistant glass door and window or curtain wall is far lower than that of an A-type heat-insulating and fire-resistant glass door and window or curtain wall.
Description
Technical field
The utility model belongs to the building glass door and window or glass cuts off curtain wall, and particularly a kind of refractory heat-insulating glass door and window or glass with fire prevention time limit more than 3 hours cuts off curtain wall system.
Background technology
Traditional C class single-sheet fire-resistant glass door and window or curtain wall are because the physical characteristic of glass material itself begins softening transform under 700 ℃ the condition of high temperature.When running into fire, single-sheet fire-resistant glass door and window or curtain wall ambient temperature in the very short time sharply rises, in violent burning fire calamity, temperature is very soon near 1000 ℃, rising along with temperature, single-sheet fire-resistant glass is softening, sagging, it is thin to draw, and finally can break away from metal edge frame and can't cut off spreading of fire, so the fire prevention time limit of C class single-sheet fire-resistant glass is generally within 2 hours.In addition, because single-sheet fire-resistant glass does not have good heat insulating function, heat might be radiated the back of the body fire face of flame resistant glass, thereby the incendivity object of the fiery face of the back of the body that ignites causes spreading of fire.
The insulating fire-retarding glass of category-A insulating fire-retarding glass door and window or curtain wall is the MULTILAYER COMPOSITE sandwich structure, heat-insulating capability slightly is better than single-sheet fire-resistant glass door and window or curtain wall, but because the restriction of its production technology, make the space of a whole page of glass cannot do greatly (generally below 3 meters), therefore can't be fit to the curtain wall that surpasses 3 meters height spaces of a whole page of modern architecture.The category-A insulating fire-retarding glass is also owing to adopt the heat-barrier material of composite colloid shape, anti-ultraviolet ability is subjected to can wearing out after the irradiation of sunlight for a long time, jaundice, bubble occur, phenomenon such as the layering of coming unstuck, influence the outward appearance of door and window or curtain wall, be not suitable for being applied to sunlit occasion.In price, the price of category-A insulating fire-retarding glass is between 10 to 20 times of C class single-sheet fire-resistant glass.
Summary of the invention
The purpose of this utility model is on C class single-sheet fire-resistant glass door and window or curtain wall basis, provides a kind of fire-proof and thermal-insulation time to reach the insulating fire-retarding glass door and window more than 3 hours or cuts off curtain wall.
Insulating fire-retarding glass door and window of the present utility model or partition curtain wall comprise the fire prevention steel frame of flame resistant glass, this flame resistant glass of clamping, it is characterized in that, spray equipment is arranged at the top of described fire prevention steel frame, and this spray equipment connects the fire water supply of building, and the spray equipment valve is controlled by heat detector.
In the preferred case, the heat detector fire prevention steel frame that reclines.
Spray equipment is fan nozzle preferably, in order to form cascade.
The utility model is when running into the inside fire generation, be elevated to the desired temperature of heat detector when interior temperature, automatically the spray valve of fetching boiling water after heat detector triggers, water is the fiery face that is subjected to that fan shape is injected in flame resistant glass from spout, flame resistant glass is being subjected to the temperature decline of current contact back, keep the integrality of glass and do not burst, the current that spray can cut off flame to the heat impact of glass, simultaneously current are to the glass cooling of lowering the temperature, unexposed surface temperature keeps at a lower temperature always, plays heat-blocking action, and the fire prevention time reaches more than 3 hours at least, the time requirement that can be applicable to prevent fires is higher, simultaneously building fire is had the place of heat insulation requirement.The utility model can use C class single-sheet fire-resistant glass, aspect the cost cost well below category-A insulating fire-retarding glass door and window or curtain wall.
Description of drawings
Fig. 1 is a kind of embodiment schematic diagram of the utility model.
The specific embodiment
Insulating fire-retarding glass door and window or the partition curtain wall of automatic spray fire extinguishing shown in Figure 1 comprise the fire prevention steel frame of being made up of the fire prevention steel profile 1, fire prevention steel frame 1 clamping single-sheet fire-resistant glass 2, the clip position between framework 1 and the flame resistant glass 2 be lined with fire prevention expanding sealing strips 3 make prevent fires heat insulation, shockproof and leave the sufficient thermal expansion of flame resistant glass space between steel frame 1 and the flame resistant glass 2.Link 4 is arranged at the top of fire prevention steel frame 1, and spray equipment 5 is hung on the link 4, and spray equipment 5 is by the fire water supply of pipeline connection building, and the valve of spray equipment 5 is controlled by heat detector.
The spray equipment 5 preferred fan nozzles that adopt are in order to form cascade at glass surface.Under the bigger situation of door and window or width of curtain wall, spray equipment 5 needs to install many covers, determines distance between the spray equipment 5 according to the water yield of the hydraulic pressure of fire water supply and spray equipment nozzle, makes the whole covering glass door and window of current or the curtain wall of spray.
Flame resistant glass 2 can use C class single-sheet fire-resistant glass reducing cost, and avoid jaundice, bubble occurring after long-time the use, phenomenon such as the layering of coming unstuck.The triggering temperature of heat detector can be selected according to the actual requirements, the general selection is 60-100 ℃ of scope internal trigger, the heat detector fire prevention steel frame 1 that preferably reclines, the heat conduction by fire prevention steel frame 1 make temperature that heat detector records as far as possible near the temperature around door and window or the curtain wall.
Claims (3)
1. the insulating fire-retarding glass door and window of automatic spray fire extinguishing or cut off curtain wall, the fire prevention steel frame that comprises flame resistant glass, this flame resistant glass of clamping, it is characterized in that, spray equipment is arranged at the top of described fire prevention steel frame, this spray equipment connects the fire water supply of building, and the valve of spray equipment is controlled by heat detector.
