Description

Technical Field

[0001] The utility model belongs to the technical field of fireproof doors, in particular to a steel heat-insulating fireproof door. Background Art

[0002] Fire doors refer to doors that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. They are fireproof partitions with a certain degree of fire resistance, installed between fire compartments, evacuation stairwells, vertical shafts, etc. At present, there are many types of fire doors, among which heat-insulating fire doors mostly use the method of setting insulation boards to improve the thermal insulation effect, but the thermal insulation effect is general, and the door body cannot be cooled in time. When a fire occurs, the heat conduction is fast, the door body temperature will rise rapidly, the fire resistance time is short, and the fireproof effect is poor. Utility Model Content

[0008] A water supply assembly, wherein two water supply assemblies are arranged at the upper ends of both sides of the door body; the outlet end of the water supply assembly is connected to the water inlet of the cooling pipe group on the same side;

[0009] Spray assembly, there are two spray assemblies, which are arranged at the upper ends of both sides of the door body and located at the lower end of the water supply assembly; the inlet end of the spray assembly is connected to the outlet of the cooling pipe group on the opposite side.

[0010] The cooling pipe group is a serpentine pipe structure, arranged on both sides of the functional panel group and in the cavity formed by the steel outer panel shell; when a fire occurs, the water supply component is started to supply water to the cooling pipe group. The water flows in the cooling pipe group to cool the door body and play a role in heat insulation. After flowing in the cooling pipe group, the temperature of the water increases and the cooling effect becomes worse. The water can flow to the spray component to be sprayed out for fire extinguishing, thus achieving secondary utilization.

[0011] Furthermore, the door frame is provided with a temperature sensor and an alarm.

[0012] A controller is set up to receive signals from the temperature sensor. When a fire occurs and the temperature rises, the temperature sensor transmits a signal to the controller. The controller controls the alarm to sound and notifies personnel to check. According to the on-site situation, the water supply component is started to cool the door body and spray at the same time.

[0013] Furthermore, the functional panel group includes a glass wool panel located in the middle, heat insulation panels arranged on both sides of the glass wool panel, and flame retardant panels arranged on both sides of the two heat insulation panels. The glass wool panel has the functions of heat insulation and sound insulation.

[0014] Furthermore, the water supply assembly includes an openable storage box fixed on the door body, a water pump disposed in the storage box, and a water supply pipe connected to the water outlet of the water pump and housed in the storage box; the water outlet of the water pump is connected to the water inlet of the cooling pipe group on the same side.

[0015] A backup power supply can be set up to power the water pump; when the water supply component needs to be used, open the storage box, pull out the water supply pipe, connect the external water source, start the water pump to pump water, and the water enters the cooling pipe group and flows.

[0016] Furthermore, the water supply pipe is a retractable corrugated pipe, the inlet end of the water supply pipe is provided with a quick-connect joint, and the inside of the quick-connect joint is provided with an elastic plug-in ring sleeve, which can be connected to external water pipes of different sizes.

[0017] Furthermore, the spray assembly includes a support plate fixed on the door body, a water distribution pipe arranged on the support plate, and a plurality of nozzles arranged below the support plate and connected to the water distribution pipe; the water distribution pipe is connected to the water outlet of the cooling pipe group on the opposite side. Water flows in the cooling pipe group to cool the door body, and the water temperature rises, enters the water distribution pipe on the opposite side, and is sprayed out by the nozzle.

[0018] Compared with the prior art, the steel heat-insulating fireproof door described in the utility model has the following advantages:

[0019] (1) The steel heat-insulating fireproof door described in the utility model has a reasonable structural design. Water is introduced into the cooling pipe group through the water supply component to cool the door body, which can prevent the door body temperature from rising rapidly, effectively extend the fire-resistant time, and optimize the insulation effect;

[0020] (2) In the steel heat-insulating fireproof door described in the utility model, the water with increased temperature after flowing in the cooling pipe group can flow to the spray assembly and be sprayed out for fire extinguishing, thus realizing secondary utilization.
