New type description: [Technical field to which the new type belongs] [0001] This creation relates to a fire door panel anti-deformation structure, which mainly refers to a type that can reduce the heat deformation of the fire door panel to improve fire safety. [Previous technology] [0002] Fire doors are the main fire safety building materials for modern buildings, and the fire doors can provide heat resistance and prevent flame penetration to have fire safety functions, and countries generally have fire standards to make the heating surface on the side of the door. When heated to the set temperature (925 ° C in China), the temperature of the non-heating surface on the other side of the door body must not be higher than the set back temperature (260 ° C in China), and the deformation of the door body must not exceed the set curvature to prevent outside The flame penetrates the inside of the body from the deformed door gap. [0003] Conventional fire door panels are mostly made of metal, and the fire door is provided with a heat insulating material in the metal door panel to prevent heat, but due to the metal characteristics, it will cause a large deformation when heated, so the current fire door test is aimed at The position of the fire door's side edge is the main test point to ensure that the fire door's side edge does not create a large fire gap. [0004] Please refer to the eighth figure, which is one of the conventional structures, and the fire door 1 'has metal door plates 11' on both sides, and a heat insulating material 12 'is provided between the two door plates 11', and the fire door Γ is set in the outer frame 2 ', and when heated by one side door panel 11' of the fire door Γ (as shown by the arrow), the fire door Γ will bend toward the heating direction, but will be generated when the door panel 11 'is heated. The center is convex and the side is bent correspondingly, which will cause the side bending deformation to be too large and produce a large gap a with the outer frame 2 ', and the larger the area of the door panel 11' will cause the side deformation to be relatively larger, and The larger gap a will further cause a passage for the flame to penetrate, so it is not easy for the conventional metal fire door to deform 1012015438-0 101204741 ^ Single number A〇101 Page 3 of 19 M431940 [0005] [0006] [0007] [0008] Reduction of loss. Although the conventional structure can be provided with a skeleton inside the fire door to reduce the amount of deformation, the skeleton itself will also be heated and bent when the skeleton is made of metal. Therefore, it is still difficult to reduce the door panel by the anti-deformation design of the skeleton. 11 'The amount of thermal deformation of the side edge. [New content] The main purpose of this creation is to provide a design of the central part and side parts of the door panel to reduce the amount of heat deformation of the door panel. Another purpose of this creation is to provide a central and lateral arrangement of the door panel that can provide thermally deformed extensions to further reduce the amount of thermal deformation of the door panel and have a combined overall texture.

The two sides of the central part and the inner ends of the two side parts are respectively fixed by spot welding or other methods. When the door body is formed by this creation, two door panels can be provided, and a heat insulating material is provided in the two door panels, and a side frame is provided on the side. Therefore, when the fire-resistant door panel on one side is heated, the area of the central part is smaller than that of the conventional fire-resistant door panel, which can have a small amount of deformation and slow down the influence of the side deformation. The amount of deformation at the outer end of the side can be effectively reduced to prevent a large fire gap between the side edge of the door panel and the outer frame, and it can have better fire safety effects. The first and second extensions corresponding to the different directions of the central and two sides of the plate surface can be set on the two sides of the central part and the inner ends of the two sides, respectively. The extensions are joined by spot welding or other suitable methods, so that the first and second extensions can be heated when it is heated 101204741 ^^^ 11 A0101 Page 4 of 19 1012015438-0 M431940 to provide deformation space to further reduce the central part , The amount of deformation on both sides.

The inner side is bent with a side wall, and the side wall is extended with a second joint end toward the first joint end, and the first joint end of the central part and the second joint end of the two side parts are fixedly connected. The inside of the combined door panel can not be viewed from the outside of the door panel, which can have a better overall texture, and when the central part is heated by the door panel, the central part with a smaller area can have a smaller amount of deformation when deformed, and the first curved part It can be provided to expand in the deformation direction during deformation to reduce the amount of deformation of the central portion affecting the side portion, and the side wall of the second extension of the two sides can also be expanded toward the deformation direction to reduce the amount of deformation, so that the amount of deformation at the outer end of the two sides Can be further reduced for better anti-deformation effect. [0010] In another embodiment of the present invention, the first extension of the central portion may have a side wall toward the inner side of the central portion, and have a third joint end in the direction of the side wall toward the outer side of the central portion; Can be bent toward the inner surface of the side, with the end edge facing the center of the side, with a second bend and a fourth joint end, and the second extension of the two sides can be placed at the first extension of the center The third joint end and the fourth joint end are fixedly connected, and the combined position is located inside the combined door panel, which cannot be viewed from the outside of the door panel, and can have a better overall texture. When the door panel is heated, the central part is deformed by heat In this case, the central portion with a smaller area may have a smaller amount of deformation, and the first extension of the central portion may be expanded toward the heating direction, and the first extension is a second extension of the traction side, and the second extension The second curved portion of the segment can be deformed correspondingly to reduce the amount of deformation at the outer end of the side portion for better deformation resistance. 10120474 Production Order No. Α ° 1ίΗ Page 5 of 19 1012015438-0 M431940 effective.
