Description

Technical Field

[0001] This utility model relates to the field of fire door technology, and more specifically, to a heat-insulating fire door. Background Technology

[0002] Insulated fire doors are fire doors that can simultaneously meet the requirements of fire resistance integrity and heat insulation in the event of a fire. They belong to Class A fire doors. Their main function is to prevent the spread of fire and the diffusion of high-temperature smoke, thus buying precious time for personnel evacuation. Insulated fire doors must maintain structural stability, prevent flame penetration, and limit heat transfer for a certain period of time.

[0003] For example, application number CN202022367721.X discloses a heat-insulating fire door, which uses a planar gear and a side locking tongue. The planar gear drives the straight toothed rack to slide horizontally, and the movement range of the side locking tongue is adjusted according to the depth of the groove. The above device solves the problem that "the structure of the fire door is a single rectangular structure, and the internal material can only block flames, but it is difficult to block the explosion caused by the fire. The explosion can easily damage the door body and affect the efficiency of the door body in blocking fire. In addition, during the use of the fire door, it is difficult to adjust the heat dissipation and locking structure of the door body according to the intensity of the fire, which makes the single locking tongue structure easily affected by the fire, increasing the safety of the door body in the locking and limiting process." However, traditional fire door core panels mostly use expanded perlite or rock wool materials, which can easily lead to low heat insulation efficiency. In addition, some manufacturers use cheap rock wool to replace aluminum silicate fiber in order to reduce costs, which can further reduce the fire resistance performance. Furthermore, poor control of the gap between the door body and the ground can easily lead to smoke leakage.

[0004] Therefore, a heat-insulating fireproof door is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a heat-insulating fireproof door to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a heat-insulating fireproof door, comprising a fireproof door body, a hinge body, an observation window, and a first adaptive sealing mechanism. The fireproof door body is provided in two sets, and a hinge body is provided at the edge of the side end face of the fireproof door body. An observation window is provided through the side end face of the fireproof door body, and a groove is provided at the edge of the fireproof door body. The fireproof door body is connected to the first adaptive sealing mechanism through the groove.

[0007] The first adaptive sealing mechanism includes a corrugated nickel-titanium shape memory alloy and borosilicate rubber. The outer surface of the corrugated nickel-titanium shape memory alloy is surrounded by borosilicate rubber, and the outer surface of the borosilicate rubber is inlaid with a ceramic fiber layer. Two sets of corrugated nickel-titanium shape memory alloy are provided, and the two sets of corrugated nickel-titanium shape memory alloy are arranged side by side. The outer surface of the borosilicate rubber is coated with a first nano-alumina coating.

[0008] Preferably, a second adaptive sealing mechanism is provided at the four corners of the fire door body, and the second adaptive sealing mechanism includes a limiting block and a nickel-titanium alloy memory plate. The upper end face and the side end face of the limiting block are provided with grooves, and the nickel-titanium alloy memory plate is embedded in the limiting block through the grooves. A sealing gasket is provided at the edge of the nickel-titanium alloy memory plate.

[0009] Preferably, the fire door body is composed of an outer protective layer, a titanium alloy honeycomb panel, a heat insulation layer and an inner protective layer. The outer protective layer is sprayed on one side of the titanium alloy honeycomb panel, and a heat insulation layer is provided on the side of the titanium alloy honeycomb panel away from the outer protective layer. The inner protective layer is provided on the side of the heat insulation layer away from the outer titanium alloy honeycomb panel.

[0010] Preferably, the observation window includes tempered glass and a nano-ceramic coating, wherein two sets of tempered glass are provided, and an aerogel microcapsule is provided between the two sets of tempered glass.

[0011] Preferably, the outer protective layer is a reflective heat-insulating coating, the titanium alloy honeycomb panel is a honeycomb panel made of titanium alloy with titanium alloy plates arranged on both sides of the honeycomb panel, the heat insulation layer is an aerogel heat insulation block with several groups of aerogel heat insulation blocks, and the inner protective layer is a stainless steel plate.

[0012] Preferably, the fire door body is provided in two sets, and the two sets of fire door bodies are symmetrically arranged. The hinge bodies installed at the edges of the fire door bodies are symmetrically arranged, and the fire door bodies are connected to the external wall by bolts through the hinge bodies.

[0013] Preferably, the fire door body is connected to the external wall via a hinge body to form a rotating structure that rotates around the center of the hinge body, and a temperature sensor is provided on the side end face of the fire door body.

[0014] Preferably, the temperature sensor installed on the side end face of the fire door body is electrically connected to an electric door closer, and the electric door closer is installed at the edge of the upper end face of the fire door body. The observation window is installed on the side end face of the fire door body by means of a fastener.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] Compared with existing technologies, this insulated fire door uses aerogel insulation blocks arranged in an insulation layer as the insulation material, thereby solving the problem that "traditional fire door core panels mostly use expanded perlite or rock wool, which easily leads to low insulation efficiency, and some manufacturers use cheap rock wool instead of aluminum silicate fiber to reduce costs, which further easily leads to a decrease in fire resistance." Furthermore, the first and second adaptive sealing mechanisms heat up and expand the corners of the fire door body, solving the problem of "poor control of the gap between the door and the ground, which easily leads to smoke leakage." At the same time, the aerogel microcapsules between the tempered glass expand when heated, forming insulated glass through the tempered glass, nano-ceramic coating and aerogel microcapsules, further achieving the insulation effect. Through the above structure, a highly efficient insulation effect is achieved.

[0017] Compared with existing technologies, this insulated fire door utilizes a fire door body composed of an outer protective layer made of reflective heat-insulating coating, a titanium alloy honeycomb panel made of titanium alloy, a heat insulation layer made of several sets of aerogel heat insulation blocks, and an inner protective layer made of stainless steel plate. The titanium alloy honeycomb panel supports the outer protective layer, heat insulation layer, and inner protective layer. The outer protective layer, made of reflective heat-insulating coating, reflects heat. The titanium alloy honeycomb panel provides heat insulation, while the heat insulation layer further enhances the insulation. The inner protective layer, made of stainless steel plate, protects the fire door body. Furthermore, two sets of fire door bodies are installed. When the fire door body is installed with a hinge, it is limited to rotate. The hinge rotates the fire door body by 90 degrees, which facilitates the heat insulation effect. The observation window allows for observation of the other side of the fire door body. In the event of a fire, the fire door body is heated, and the fire door body provides heat insulation and fire protection. When the fire door body is heated, the aerogel microcapsules between the two tempered glass panes expand and fill the gap between the tempered glass panes. The tempered glass, nano-ceramic coating, and aerogel microcapsules form heat-insulating glass, thus achieving the effect of heat insulation and fire protection.

[0018] Compared with existing technologies, this insulated fire door, in its use, utilizes a first adaptive sealing mechanism and a second adaptive sealing mechanism to heat and expand the corners of the fire door body, solving the problem of "poor control of the gap between the door body and the ground, which easily leads to smoke leakage". When the fire door body is heated, the corrugated nickel-titanium memory alloy in the first adaptive sealing mechanism and the nickel-titanium alloy memory plate in the second adaptive sealing mechanism are simultaneously heated, causing the corrugated nickel-titanium memory alloy and the nickel-titanium alloy memory plate to expand, making the fire door body tightly fit with the surroundings, thereby preventing smoke leakage. When the corrugated nickel-titanium memory alloy expands, it drives borosilicate rubber to fill the gaps between the fire door body and the surroundings. Furthermore, the ceramic fiber layer and the first nano-alumina coating improve the heat resistance of the borosilicate rubber, thereby preventing smoke leakage. At the same time, the nickel-titanium alloy memory plate connected by the limiting block expands with heat, thereby making the sealing gasket tightly fit with the surroundings, thus preventing smoke leakage. The above structure solves the problem of smoke leakage. Attached Figure Description

The adaptive sealing mechanism 4 includes a corrugated nickel-titanium shape memory alloy 41 and borosilicate rubber 42. The outer surface of the corrugated nickel-titanium shape memory alloy 41 is surrounded by the borosilicate rubber 42, and the outer surface of the borosilicate rubber 42 is inlaid with a ceramic fiber layer 43. Two sets of corrugated nickel-titanium shape memory alloy 41 are arranged side by side. The outer surface of the borosilicate rubber 42 is coated with a first nano-alumina coating 44. A second adaptive sealing mechanism 45 is provided at the four corners of the fire door body 1.

The upper and side surfaces of the fire door body 1 are provided with grooves, and a nickel-titanium alloy memory plate 452 is embedded in the limiting block 451 through the grooves. A sealing gasket is provided at the edge of the nickel-titanium alloy memory plate 452. The first adaptive sealing mechanism 4 and the second adaptive sealing mechanism 45 cause thermal expansion at the corners of the fire door body 1, solving the problem of "poor control of the gap between the door and the ground, which easily leads to smoke leakage." When the fire door body 1 is heated, the wavy nickel-titanium memory alloy 41 in the first adaptive sealing mechanism 4 and the nickel-titanium alloy memory plate 452 in the second adaptive sealing mechanism 45 are heated simultaneously, causing the wavy nickel... The titanium memory alloy 41 and the nickel-titanium alloy memory plate 452 expand when heated, making the fire door body 1 fit tightly against the surroundings to prevent smoke leakage. When the wavy nickel-titanium memory alloy 41 expands, it drives the borosilicate rubber 42 to fill the gaps between the fire door body 1 and the surroundings. The ceramic fiber layer 43 and the first nano alumina coating 44 are used to improve the heat resistance of the borosilicate rubber 42 and prevent smoke leakage. At the same time, the nickel-titanium alloy memory plate 452 connected by the limiting block 451 expands when heated, making the sealing gasket fit tightly against the surroundings to prevent smoke leakage and solve the problem of smoke leakage.

[0032] The fire door body 1 consists of an outer protective layer 11, a titanium alloy honeycomb panel 12, a heat insulation layer 13, and an inner protective layer 14.

The outer protective layer 11 is made of reflective heat-insulating coating, the titanium alloy honeycomb panel 12 is made of titanium alloy, and the heat insulation layer is made of several sets of aerogel heat insulation blocks.

A titanium alloy honeycomb panel 12 supports the outer protective layer 11, the heat insulation layer 13, and the inner protective layer 14. The outer protective layer 11, made of reflective heat-insulating coating, reflects heat. While the titanium alloy honeycomb panel 12 provides heat insulation, the heat insulation layer 13 further enhances the insulation. The inner protective layer 14, made of stainless steel plate, protects the fire door body 1. The heat insulation material consists of aerogel heat insulation blocks arranged in the heat insulation layer 13. This addresses the problem that "traditional fire door core panels often use expanded perlite or rock wool, which easily leads to low heat insulation efficiency, and some manufacturers use cheap rock wool instead of aluminum silicate fiber to reduce costs." This further addresses the issue of "easily leading to a decrease in fire resistance," and an inner protective layer 14 is provided on the side of the insulation layer 13 away from the outer titanium alloy honeycomb panel 12. Specifically, the inner protective layer 14 is a stainless steel plate. The observation window 3 includes tempered glass 31 and a nano-ceramic coating 32. Two sets of tempered glass 31 are provided, with aerogel microcapsules 33 positioned between them. The tempered glass 31, nano-ceramic coating 32, and aerogel microcapsules 33 form an insulating glass structure, thereby achieving a heat insulation and fireproofing effect. The aerogel microcapsules 33 between the tempered glass 31 expand when heated, further enhancing the heat insulation effect and achieving highly efficient heat insulation. Through the observation window 3... To facilitate observation of the other side of the fire door body 1, in the event of a fire, the fire door body 1 is heated, and the aerogel microcapsules 33 between the two sets of tempered glass 31 expand due to the heat, filling the gap between the tempered glass 31. Two sets of fire door bodies 1 are provided, and the two sets of fire door bodies 1 are arranged symmetrically. Hinges 2 are installed symmetrically at the edges of the fire door body 1, and the fire door body 1 is bolted to the external wall via the hinges 2.

The observation window 3 is installed on the side surface of the fire door body 1 by a snap-fit ​​mechanism. When installing two sets of fire door bodies 1, the fire door body 1 is limited by the hinge body 2 to allow rotation.

In this embodiment, the reflective heat-insulating coating, titanium alloy, etc., are commercially available materials known to those skilled in the art. They can be customized or selected according to actual needs. Here, we only use them without making any structural or functional improvements, and we will not elaborate further.

[0033] The working process of this utility model is as follows: First, the fire door body 1, composed of an outer protective layer 11 made of reflective heat-insulating coating, a titanium alloy honeycomb panel 12 made of titanium alloy, a heat insulation layer 13 made of several sets of aerogel heat insulation blocks, and an inner protective layer 14 made of stainless steel plate, achieves the effect of heat insulation. The outer protective layer 11 made of reflective heat-insulating coating reflects heat. The titanium alloy honeycomb panel 12 provides heat insulation, while the heat insulation layer 13 further insulates the door. The inner protective layer 14 made of stainless steel plate protects the fire door body 1. The hinge body 2 limits the installation of the fire door body 1, allowing it to rotate. The observation window 3 facilitates observation of the other side of the fire door body 1. When a fire occurs, the fire door body 1 is heated, utilizing its heat insulation and fireproofing effects.

Simultaneously, the corrugated nickel-titanium memory alloy 41 in the first adaptive sealing mechanism 4 and the nickel-titanium alloy memory plate 452 in the second adaptive sealing mechanism 45 are heated, causing them to expand and tightly fit the fire door body 1 against its surroundings. When the corrugated nickel-titanium memory alloy 41 expands, it drives the borosilicate rubber 42 to fill the gap between the fire door body 1 and its surroundings. The ceramic fiber layer 43 and the first nano-alumina coating 44 enhance the heat resistance of the borosilicate rubber 42. Simultaneously, the nickel-titanium alloy memory plate 452, connected by the limiting block 451, expands, further ensuring a tight fit between the sealing gasket and its surroundings, preventing smoke leakage.
