Technical Field
The invention relates to the field of building fire protection, in particular to a building fire protection and prevention device.
Background
At present, along with the development of urban economy, high-rise buildings are continuously increased, and the high-rise buildings in China are rapidly developed, except for building functions and urban planning requirements, the high-rise buildings are mainly determined by urban population concentration and shortage of construction land. Under the conditions of more and more population and more tense urban land, the high-rise building can be built, so that the land resource can be effectively saved, the building cost can be reduced, and the building cost can be increased
High urban greening rate and improved living environment of urban residents.
When high-rise building construction, need build scaffold help construction at the building outer wall, in the construction work of scaffold, need use a large amount of safety nets and wooden scaffold board, the conflagration takes place very easily. The fire fighting is usually carried by a fire hose or a fire extinguisher to extinguish fire, but due to the fact that the speed of people getting on and off a high-rise building is low, the fire is developed quickly, and the expected fire fighting effect cannot be achieved. In addition, the safety net causes the pollution in the external scaffold easily during concrete construction, and is higher because of the scaffold, and the safety net is difficult to wash.
On some building sites, a fire-fighting spraying system can be built when a scaffold is built by a construction side, fire can be controlled emergently in a spray head water spraying mode when a fire disaster happens, and personal safety of workers and safety of building materials are protected. The conventional fire-fighting spraying system for the construction site is generally characterized in that a fire-fighting pipeline is arranged along the outer wall of a building, the fire-fighting pipeline is connected with a water source, then spraying devices are arranged on each layer of a scaffold, the spraying devices are connected with the fire-fighting pipeline, an electromagnetic valve is arranged on the fire-fighting pipeline, and the remote control is realized through a switch box on the ground; when a fire disaster occurs, ground workers remotely control the fire-fighting spraying system to work through the switch box, so that the spraying devices on all layers of the scaffold spray water, and the purpose of fire extinguishment is achieved. However, such fire sprinkler systems are often simple in structure and still have many drawbacks, and the expected fire extinguishing effect cannot be achieved in case of an emergency fire.
The patent with the patent number of CN 203436717U provides a fire-fighting spray device for an external scaffold for high-rise building construction, wherein a vertical main fire-fighting pipeline is fixed on a building, the main fire-fighting pipeline is communicated with a transverse fire-fighting pipeline which is transversely arranged, the lower end of the main fire-fighting pipeline is communicated with a water supply source, the transverse fire-fighting pipeline extends into a scaffold structure, a spray pipeline is arranged at the outer end of the transverse fire-fighting pipeline along the horizontal direction, the spray pipeline is fixed on the scaffold, spray holes are formed in the spray pipeline, and a valve is arranged on the transverse fire-fighting pipeline; the valve on the transverse fire-fighting pipeline is an electromagnetic valve or a manual butterfly valve; the spraying pipeline is connected with the transverse fire-fighting pipeline through a tee joint, and the transverse fire-fighting pipeline is connected with the main fire-fighting pipeline through a joint; the lower end of the main fire-fighting pipeline is connected with a fire-fighting water pipe or is connected with the output end of a water pump in the water tank through a pipeline. When a fire disaster happens, ground workers open the remote control switch box to enable water to be sprayed out from the water spraying holes to extinguish the fire, so that the fire extinguishing effect is achieved. However, the patent does not consider that when a fire occurs on a construction site, ground workers often cannot find the fire immediately, cannot open the remote control switch box in time, cannot take effective measures aiming at the fire in the first time, often miss the best fire extinguishing occasion, and the practicability of the fire extinguishing box is greatly limited.
Patent No. CN 204364736U's patent has proposed a fire control shower nozzle, and it includes that the tube-shape has the body of external screw thread, and body and water piping connection are connected with the frame on the body, and the dish that dabbles is installed to the frame upper end, and the dish terminal surface that dabbles passes through the fixed screw to be realized rather than fixed connection, and the body terminal surface is equipped with the ball seat, is equipped with the temperature sensing element subassembly that can play and open or close the fire control shower nozzle between ball seat and the frame top. When the conflagration breaing out, when ambient temperature risees to the action temperature, easily melt soldering tin and receive high temperature melting, little copper spare displacement upwards for T shape frame breaks away from the set-square, and whole mechanism takes place out of balance, and is whole to drop, begins the water spray and puts out a fire, and the purpose that automatic work began putting out a fire when realizing meetting the condition of a fire begins to put out a fire. However, the water spraying radius of the spray head is not improved, the water spraying radius of the common spray head is often smaller, the fire extinguishing efficiency is low, and the emergency fire cannot be dealt with.
The applicant provides a spraying fire extinguishing device for a construction site, and aims to solve the problem that fire cannot be effectively extinguished in time when a fire occurs in the construction site.
