Problems solved by technology

[0003] As long as the conventional fire doors block the fire through steel or steel-wood doors with flame retardants, they can prevent the fire from expanding within a certain period of time, but in a closed room where important equipment is installed, it is neither possible to transfer the equipment nor easy to extinguish the fire. , even if the fire door can temporarily stop the fire, it is still easy to cause equipment burns and property damage
[0004] Moreover, the conventional fire doors themselves do not have the functions of cooling and heat dissipation. If the fire doors cannot be cooled and insulated in time, the time for blocking the flame will be greatly reduced. If the firefighters cannot arrive in time, the fire doors will be burned. greatly increased risk

Embodiment 1

[0032] Such as figure 1 As shown, on the basis of the structure of Embodiment 1, an annular accommodating groove 4 is concavely formed on the circumferential side wall of the door panel 1, and a fireproof sealing strip is embedded in the annular accommodating groove 4, and the fireproof sealing strip is Water-swellable sealing strip5. In this structure, under normal conditions, there is an appropriate amount of gap between the outer side of the fireproof sealing strip and the inner side of the door frame 2, which is used to prevent the door panel 1 from being stuck by the fireproof sealing strip when the door panel 1 is closed, affecting the opening and closing of the door panel.

[0033] A water passage for passing cooling water is provided inside the door panel 1 , the water passage includes a plurality of annular pipes 6 , and the annular pipes 6 communicate with each other. A plurality of water outlets 6.1 are provided in the circumferential direction on the annular pipel...

Embodiment 2

[0038] Such as figure 2 , 3 As shown, a glass window 110 is also provided on the door panel 1, and the glass window 110 includes a glass frame 9 and a fireproof glass 10; the glass frame 9 is made of a fireproof material.

[0039] Specifically, an installation opening 1.1 is provided on the door panel 1, and the glass frame 9 is fitted in the installation opening 1.1. The inner wall of the glass frame 9 is provided with an annular installation groove 9.1, and the surroundings of the fireproof glass 10 are embedded in the installation groove 9.1.

[0040] As an improvement, when the fireproof glass 10 is embedded in the glass frame 9, squeeze and fill the fireproof glue in the installation groove 9.1 in the glass frame 9 to further improve the installation stability of the fireproof glass 10 and improve the fireproof glass 10 weeks. Directional sealing performance.

[0041] Preferably, the fireproof glass 10 has a double-layer structure, and a gap is provided between the tw...

Embodiment 3

[0043] Such as Figure 4 As shown, on the basis of the second embodiment, a number of dovetail grooves 11 are provided on the circumferential side wall of the mounting opening 1.1 on the door panel 1 along the thickness direction of the door panel 1, and are convex on the circumferential side wall of the glass frame 9. There are a plurality of limit protrusions 12 fitted with dovetail grooves 11. When the glass frame 9 is embedded in the installation port 1.1, each limit protrusion 12 on the glass frame 9 is fitted in the corresponding position one by one. in the dovetail groove 11.

[0044] Such as Figure 5 As shown, preferably, an annular fireproof sealing strip 13 is set on the peripheral outer wall of the glass frame 9 , and the limiting protrusion 12 is arranged on the outer sidewall of the fireproof sealing strip 15 .

[0045] Further, the fireproof sealing strip 13 is a fireproof sealing strip with a thermal expansion effect. When a fire occurs, the fireproof sealing...

Abstract

The invention discloses a door structure for a fire fighting access. The door structure comprises a door panel and a door frame, wherein the circumferential outer side wall of the door panel sinks inwards so as to form an annular containing groove, and a water swelling sealing rubber strip is embedded in the annular containing groove; the door panel is internally provided with a plurality of annular pipelines, and all the annular pipelines are communicates with each other; a plurality of water outlets are circumferentially formed in the door panel near the annular pipeline arranged at the outermost side, and are communicated with the bottom of the annular containing groove; the lower end of the door panel is provided with a water inlet communicated with the annular pipelines; a wall body is provided with a water supply mechanism, and the water supply mechanism is provided with a water outlet pipe. When the door is closed, the water outlet pipe is communicated with the water inlet; thewall body is provided with a smoke sensor and a controller. The smoke sensor and the water supply mechanism are separately and electrically connected with the controller. The invention provides the door structure for the fire fighting access, and a cooling passage is arranged inside the door structure; when a fire hazard occurs, a door body is cooled in time, so that the fire blocking time is prolonged.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, in particular to a door structure for a fire-fighting passage. Background technique [0002] A fire door is a door that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. It is a fire-resistant partition with certain fire resistance located in fire compartments, evacuation stairwells, vertical shafts, etc. In addition to the function of ordinary doors, fire doors also have the function of preventing the spread of fire and smoke. It can prevent the spread of fire within a certain period of time and ensure the evacuation of people. [0003] As long as the conventional fire doors block the fire through steel or steel-wood doors with flame retardants, they can prevent the fire from expanding within a certain period of time, but in a closed room where important equipment is installed, it is neither possible to tran...
