Technical Field
[0001] The present invention relates to the technical field of fireproof doors, and in particular to a heat-insulating, waterproof and 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. Fire doors have the function of preventing the spread of fire and smoke, and can prevent the spread of fire within a certain period of time to ensure the evacuation of personnel.
[0003] However, when the existing waterproof fireproof door encounters a fire, special fireproof materials are filled between the door and the door frame to delay the spread of the fire. However, in a high temperature environment, the thermal insulation effect is poor, which may cause harm to the users inside the door. For this reason, we propose a thermal insulation waterproof fireproof door. Summary of the invention
[0004] In order to solve the above-mentioned technical problems, the present invention provides a heat-insulating, waterproof and fire-proof door.
[0005] The present invention is implemented by the following technical scheme: a heat-insulating, waterproof and fire-proof door, comprising a door panel, a placement rack is fixedly connected to the front of the door panel, an installation opening is opened on the front of the door panel, a baffle is slidably connected inside the installation opening, a handle and a lock are installed on the front of the door panel, the door panel comprises a main board, a reinforcement layer is fixedly connected to the top and bottom of the main board, a fireproof layer is installed on the surface of the reinforcement layer, a heat insulation layer is installed on the top of the fireproof layer, a waterproof membrane is installed on the surface of the heat insulation layer, and a touch layer is installed on the surface of the waterproof membrane.
[0006] As a further improvement of the above solution, the back of the door panel and the back of the baffle are fixedly connected to a limiting plate, and the internal threads of the limiting plate are connected with bolts to facilitate the limiting and fixing of the baffle.
[0007] As a further improvement of the above solution, two triangular support blocks are fixedly connected to the bottom of the placement rack, and the backs of the triangular support blocks are fixedly connected to the front of the door panel, thereby improving the stability of the placement rack support.
[0008] As a further improvement of the above solution, the reinforcement layer includes a steel frame, the surface of which is cast by concrete and is used to support and protect the main board to ensure the stability of the main board.
[0009] As a further improvement of the above solution, the fireproof layer is fixedly connected to the surface of the reinforcement layer, and the fireproof layer is formed by processing mineral fiber material to provide fireproof performance for the door panel.
[0010] As a further improvement of the above solution, the heat insulating layer includes two glass layers, and cavity blocks are fixedly connected between the two glass layers at equal intervals, so that an air layer is formed between the two glass layers, and the air can reduce heat conduction.
[0011] As a further improvement of the above solution, the waterproof film is made of a PTE film to prevent moisture from entering the mainboard.
[0012] As a further improvement of the above solution, the touch layer is a cold-rolled steel plate, which is processed by a cold rolling process and has the characteristics of solid texture, tight structure and smooth surface.
[0013] As a further improvement of the above solution, the surface of the touch layer is sprayed with paint to reduce direct contact between the touch layer and oxygen, thereby improving the rust and corrosion resistance of the touch layer.
[0014] As a further improvement of the above solution, a communication port is provided on the front side of the door panel, and an observation eye is installed inside the communication port to facilitate observation of the situation outside the door panel.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. The present invention sets a door panel. During daily use, oxygen in the air is isolated by paint, thereby reducing direct contact between the touch layer and oxygen, improving the rust and corrosion resistance of the touch layer, and increasing the service life of the device. At the same time, the touch layer is a cold-rolled steel plate, which not only has a smooth surface, but also makes the device more resistant. When encountering water, the waterproof film will separate the water to prevent moisture from entering the interior of the main board. In the event of a fire, the air layer inside the insulation layer will reduce the transfer of heat, thereby reducing the impact of heat on users in the door. At the same time, the mineral fiber material outside the fireproof layer will block the burning of fire to prevent the fire from burning the door panel. The reinforcement layer of the main board is composed of a steel frame and concrete, which makes the door panel more compact and stable.
[0017] 2. The present invention provides a prevention rack to allow the deliveryman to place the takeaway on the rack, and then rotate the bolt to release the connection between the two limit plates, lift the baffle upward, and bring the takeaway in. The takeaway or items can be brought in without opening the door panel, thereby improving the safety of the device during use. BRIEF DESCRIPTION OF THE DRAWINGS

To protect and ensure the stability of the main board 4, a fireproof layer 6 is installed on the surface of the strengthening layer 5, and the fireproof layer 6 is fixedly connected to the surface of the strengthening layer 5. The fireproof layer 6 is formed by processing mineral fiber materials, which provides fireproof performance for the door panel 1. A heat insulation layer 7 is installed on the top of the fireproof layer 6. The heat insulation layer 7 includes two glass layers, and cavity blocks are fixedly connected at equal intervals between the two glass layers, so that an air layer is formed between the two glass layers, and the air can reduce heat conduction. A waterproof membrane 8 is installed on the surface of the heat insulation layer 7. The material of the waterproof membrane 8 is PTE film to prevent moisture from entering the main board 4. A touch layer 9 is installed on the surface of the waterproof membrane 8. The touch layer 9 is a cold-rolled steel plate. The cold-rolled steel plate is processed by cold rolling process and has the characteristics of solid texture, tight structure, and smooth appearance. The surface of the touch layer 9 is sprayed with paint 10 to reduce the direct contact between the touch layer 9 and oxygen, thereby improving the rust and corrosion resistance of the touch layer 9.
[0027] The implementation principle of an insulated, waterproof and fireproof door in the embodiment of the present application is as follows: during daily use, oxygen in the air is isolated by the paint 10, thereby reducing direct contact between the touch layer 9 and oxygen, improving the rust and corrosion resistance of the touch layer 9, and increasing the service life of the device. At the same time, the touch layer 9 is a cold-rolled steel plate, which not only has a smooth surface, but also makes the device more capable of resisting fire. When encountering water, the waterproof membrane 8 will separate the water to prevent moisture from entering the interior of the main board 4. In the event of a fire, the air layer inside the insulation layer 7 will reduce the transfer of heat, thereby reducing the impact of heat on users inside the door. At the same time, the mineral fiber material outside the fireproof layer 6 will block the burning of fire to prevent the fire from burning the door panel 1. The reinforcement layer 5 of the main board 4 is composed of a steel frame and concrete, which makes the door panel 1 more compact and stable.
[0028] When a user orders takeout, he or she generally has to open the door or ask the delivery man to place the takeout at the door and go out to pick it up later. This requires the user to contact the outside world, which poses certain safety issues to the user. The device allows the delivery man to place the takeout on the placement rack 2, and then turn the bolt to release the connection between the two limit plates, lift the baffle 3 upwards, and bring the takeout in. The takeout or items can be brought in without opening the door panel 1, thereby improving the safety of the device during use.
[0029] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
