The fireproof and smoke-insulation device comprises a window in the exterior wall of a building, a main pipe fixed together with an exterior wall surface and a branch pipe communicated with the main pipe, wherein the exterior wall surface above the window is provided with a water curtain frame which is erected close to the wall and can be vertical to the exterior wall surface after being taken down; the water curtain frame is provided with a plurality of water nozzles and is connected with the main pipe through the branch pipe. The fireproof and smoke-insulation device is used for solving the technical problem of non-ideal isolating water curtain effect caused by dispersible water flow of the fireproof and smoke-insulation device for the exterior wall in the prior art. The fireproof and smoke-insulation device has the beneficial effects that the water curtain frame is usually erected close to the exterior wall surface above the window, so that the appearance of the building is not affected, and the daily life is also not affected. Once a fire happens, the water curtain frame is independently controlled to be taken down to form a 90-DEG included angle with the exterior wall surface, the automatic water inlet and supply speed is high, water is centrally supplied to form water curtain clustering so that afire dense smoke and flames are prevented from being diffused towards a higher layer through the window of the exterior wall, the spread of the fire is controlled, and the fireproof and smoke-insulation effects are good.
Description
Technical field
The utility model relates to fire prevention field, especially relates to the spacer assembly that a kind of building breaking out of fire prevents fire spreading.
Background technology
One of major disaster that can meet with in people's life is fire.Once breaking out of fire is particularly important to the control of fire spreading, this is directly connected to the number of casualties and the size of economic loss.From fire data in the past, there are fireproof door, quarantine measures such as fire prevention such as fire prevention cascade etc. in building inside, and after building catches fire, these measures have suppressed the intensity of a fire and spread to building last layer.But at the exterior wall of building, the window that big fire is easy to pass through fire bed is upwards diffused into adjacent next level window, thereby causes fire spreading to next level.Chinese patent Granted publication CN201969224U, on September 14 2011 Granted publication day, name is called the utility model patent of " a kind of exterior wall water curtain fire-extinguishing system for high-rise buildings ", discloses a kind of external wall water curtain fire extinguisher system.Comprise fire fighting supply subsystem, fire-fighting RACS, exterior wall sensing subsystem, exterior wall water curtain subsystem and indoor fire-fighting subsystem; Wherein, fire fighting supply subsystem one end is provided with two fire pumps and some siamese fire department connections, and the other end is provided with a valve group; Valve group is connected with exterior wall water curtain subsystem and indoor fire-fighting subsystem respectively; Fire-fighting RACS connects and controls exterior wall sensing subsystem, exterior wall water curtain subsystem and indoor fire-fighting subsystem; Exterior wall sensing subsystem is comprised of sensor and signal bus, and this signal bus is linked in fire-fighting RACS; Exterior wall water curtain subsystem by being responsible for, main, some arms, solenoid electric valve and fan type shower nozzle form, supervisor is connected with fire fighting supply subsystem by valve group, main is connected to supervisor and goes up, some arms are distributed on main; Solenoid electric valve and fan type shower nozzle are installed on each arm.The water outlet of the whole exterior wall water curtain subsystem of this utility model can only control to main, and this will cause need to prevent fires when isolation to one or two window of minority, and water outlet is slow, water yield disperses, and finally causes isolating water curtain effect undesirable.In addition, the arm of exterior wall water curtain subsystem and the fan type shower nozzle being installed on each arm take up room, and make troubles to the daily lifes such as user's airing.
Summary of the invention
In order to solve exterior wall water curtain fire prevention isolation device water yield in prior art, disperse the undesirable technical problem of isolation water curtain effect forming, the utility model provides a kind of skin fire-proof smoke insulation device, reach skin water curtain subregion is controlled to water outlet, effectively isolate the object of fire spreading.
The technical solution of the utility model is: a kind of skin fire-proof smoke insulation device, it comprises the window in skin, the supervisor fixing with wall face and the main being communicated with supervisor, the wall face of window top is provided with the water curtain frame that pastes wall uprightly and can put down rear vertical wall face, water curtain has set up several (operating) water nozzles, and water curtain frame is connected with supervisor by main.The room of building catches fire, and the window of smoke and fire from exterior wall comes up.Water curtain frame puts down, and water curtain frame becomes 90 degree angles to cover window top with wall face.Fire demand water flows into by being responsible for to flow out through main the water curtain frame putting down, then forms water curtain from (operating) water nozzle ejection, and the isolation intensity of a fire spreads to last layer., water supply fast for water speed is concentrated, and forms water curtain intensive, and fire-proof smoke insulation is effective.
As preferably, main sidewall is provided with apopore, and water curtain has set up T-shaped threeway, the horizontal tube of threeway and main socket, and vertical tube and the apopore of threeway adapt.Water curtain frame pastes wall does not uprightly intake, and water curtain frame puts down and becomes 90 degree angles with wall face, water curtain frame automatic feeding water.
As preferably, main sidewall outer surface is provided with outer groove, and the horizontal tube inwall of threeway is provided with inner groovy, and outer groove and inner groovy adapt, and inner groovy is connected with sealing ring.Encapsulation process is carried out in main and threeway junction, and anti-sealing outflows and reduces hydraulic pressure.
As preferably, water curtain frame comprises connecting and is cancellated transverse tube and vertical tube, and (operating) water nozzle is connected with vertical tube infall with transverse tube.
As preferably, water curtain has set up drag-line, and one end and the wall face of drag-line are fixed, and the other end of drag-line and water curtain frame are fixed; Prevent that water curtain frame from down rotating when water spray.
Compared with prior art, the beneficial effects of the utility model are: when occurring without fire, water curtain frame is affixed on window top wall face and erects, and does not affect architectural appearance, does not also hinder daily life.Once fire occurs, independent control put down water curtain frame, water curtain frame becomes 90 degree angles with wall face, automatic feeding water, fast for water speed, supply water and concentrate, formation water curtain is intensive, the dense smoke that obstruct lower floor catches fire and flare spread to last layer by the window of exterior wall, control spreading of fire, and fire-proof smoke insulation is effective.
