Description

Technical Field

[0001] This application relates to the field of building fire protection construction technology, and in particular to a concealed structure for fire hydrants in urban buildings. Background Technology

[0002] A fire hydrant, formally called a fire hose reel, is a fixed fire-fighting facility, divided into indoor and outdoor fire hydrants. A fire hydrant box is a box-shaped fixed fire-fighting device installed on the fire water supply pipeline within a building. It consists of a box body, indoor fire hydrant, fire hose connection, hose, nozzle, fire hose reel, and electrical equipment, providing functions such as water supply, fire extinguishing, control, and alarm. Fire hydrant boxes can be installed in two ways: surface-mounted and concealed. Concealed installation is a very common method, where the fire hydrant box is embedded in a pre-reserved space within the building wall.

[0003] Concealed fire hydrant boxes are embedded in the wall. If the pre-reserved opening in the wall is uneven, gaps will be left between them, weakening the anchoring effect and affecting the fire resistance of the wall. Therefore, an improvement has been made to the concealed structure of fire hydrants in urban buildings. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides a concealed structure for fire hydrants in urban buildings, which overcomes the shortcomings of the prior art and aims to solve the problems in the prior art.

[0006] By adopting the above technical solution, a fixing frame is embedded in the reserved opening in the wall, and cement mortar is filled between the fixing frame and the reserved opening. The gap is filled through the consolidation effect, which enhances the overall structural strength and prevents loosening. The inner diameter of the fixing frame is strictly matched with the outer diameter of the fire hydrant box to ensure that there is no gap after the fire hydrant box is embedded, thereby improving the anchoring stability. Rock wool board is bonded to the side wall of the fixing frame, and the inner wall of the rock wool board is made to fit the outer wall of the fire hydrant box. The non-combustible and heat insulation properties of the rock wool board are used to compensate for the damage to the fire resistance limit of the wall caused by the concealed installation.

[0007] As a preferred technical solution of this application, the fire hydrant box is rotatably connected to the front side of the box door, and a transparent glass is fixedly installed inside the box door, with a fire prevention mark affixed to the outer surface of the transparent glass.

[0010] By adopting the above technical solution, the fire hose connects the fire nozzle to the fire hydrant valve, and the fire nozzle sprays water onto the burning material to achieve multiple functions such as fire extinguishing, cooling protection, isolation, and dilution. The fire hose reel is suitable for non-professional firefighters to extinguish initial indoor fires, and the alarm is used for manual alarm to issue an alarm signal in case of fire or other emergencies.

[0011] As a preferred technical solution of this application, a placement clip is fixedly installed on the inner wall of the fire hydrant box, and the fire hose is slidably engaged with the placement clip.

[0012] By adopting the above technical solution, the fire hose nozzle body is fixed by a clamp, avoiding bending and deformation caused by gravity or compression, extending its service life, and forming a standardized access path, reducing delays caused by disorganized equipment in emergency situations.

[0013] As a preferred embodiment of this application, two fire extinguishers are placed inside the fire hydrant box below the partition.

[0014] By adopting the above technical solutions, the main function of fire extinguishers is to extinguish initial fires, prevent the fire from spreading, and thus reduce casualties and property losses.

[0015] As a preferred technical solution of this application, the fire hydrant box is made of cold-rolled thin steel plate bent and welded, and the fire hose has rubber as the inner lining and linen woven material wrapped on the outer surface.

[0016] By adopting the above technical solutions, the fire hydrant box has high strength and rigidity, which can withstand the impact of falling objects or external damage at the fire scene. The rubber lining provides a seal under high-pressure water flow to prevent leakage, and the outer flax woven material enhances wear resistance and extends the service life of fire hoses when dragged on rough ground.
