Description

    BACKGROUND OF THE PRESENT INVENTION 1. Field of the Present Invention
  • The present invention relates to a fire-resistant structure for door panel, more particularly to a fire-resistant structure with lightweight calcium silicate plates filled up inside the hollow of a door panel.
    • 2. Description of Prior Act
  • The conventional fire-resistant structure for door panel generally involves filling the hollow inside the door panel with fire-resistant materials such as foamed phenolics. Therefore, even after the door panel is burned to ashes in a fire, the fire-resistant materials filled inside the door panel are capable of obstructing flames from spreading or passing through the door.
  • For instance, the conventional door panel 10 is shown as in FIG.S. 1 and 2. The fire-resistant performance of this door panel 10 lies in the structure of two pieces of magnesium oxide plates in the same size as the face panels 11, 12 inside the face panels 11, 12; then foamed phenolics 22 are filled inside the door panel 10. Therefore, in case of a fire, such a door panel 10 will be able to prevent fire from spreading and passing through using the fire-resistant properties of the foamed phenolics 22 and the magnesium oxide plate 23.
  • In most cases, however, the foregoing conventional door panel 10 uses foamed PVC materials, plastic injection materials, wooden or steel materials to make its upper rail 13, lower rail 14, left stile 15 and right stile 16. In a burning fire, the foamed PVC materials, the plastic injection and wooden materials are easily burned; and the steel material would be bent and deformed due to its high heat conductivity, which would result in burning flames penetrating through the deformed or burned-out door structure. As shown in FIG 1 and 2, even when the conventional door panel 10 has adopted such fire-resistant materials as foamed phenolics 22 and magnesium oxide plate 23, or even filled with handle reinforcing materials 17, heat insulating materials 20 or reinforcing materials 20, there is room for improvement of its fire-resistant performance.
    • SUMMARY OF THE PRESENT INVENTION
  • It is the objective of the present invention to provide a type of fire-resistant structure for a door panel, using calcium silicate plates to comprise an upper rail, a lower rail, a left stile and a right stiles on four sides of the door panel, and lightweight calcium silicate plates to fill up inside the hollow of the door panel, thereby enabling minimized weight, reinforced structure, and excellent fire-resistant performance to the door panel; the four sides of the door panel would not be burned or deformed in a fire, the flames may be prevented from spreading or penetrating through the door panel; the flames may be kept outside the door to prevent the flames from spreading or passing through the door.
  • It is another objective of the present invention to provide a fire-resistant structure for the door panel, using reinforcing iron or other reinforcing materials and one or more calcium silicate plates to comprise an upper rail, a lower rail, a left stile and a right stiles on four sides of the door panel to reinforce the structural strength of the door panel, and increase the fire-resistant performance by keeping the flames from penetrating or reaching through the four sides of the door panel.

    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • As shown in FIGS. 3 to 7, a door panel 30 of this present invention is mainly composed of two face panels 31, 32, an upper rail 33, a lower rail 34, a left stile 35, a right stile 36, and at least one lightweight calcium silicate plate 40.
  • The face panels 31, 32 are Sheet Molding Compound (SMC) panel made of reinforced glass fibers, on their front sides are smooth surfaces without grains or with imitated grains, on their reverse sides are coarse surfaces to increase friction when the face panels 31, 32 are glued.
  • An upper rail 33, a lower rail 34, a left stile 35 and a right stile 36 are made of calcium silicate plates to enable such features as robustness, resistance to fire and combustion, and they are constituted as surrounding margins of door panel 30 when the face panels 31, 32 are assembled to form the door panel 30 of this present invention. As shown in FIG. 3 or 8, the surrounding margins of the door panel 30 as disclosed in this present invention may be formed as multiple layers of laminated structures, using one or more pieces of multiple layers of calcium silicate boards to comprise the surrounding margins of the door panel 30, thereby reinforcing the structural strength of the door panel 30, and increasing its resistance to invading fire flames.
  • Instead of filling foamed phenolics 22 or other fire-resistant materials inside the hollow of the door panel 30, at least one piece of calcium silicate plate 40 is used directly, or preferably at least one piece of lightweight calcium silicate plate 40 is used, to fill up the hollow of the door panel 30 and to comprise the lamination of the door panel 30.
  • The door panel 30 using entire calcium silicate plate 40 as door core has the advantages including lightweight, robustness, and resistance to fire and combustion, particularly, the weight of the door panel 30 shall be minimized, and in case of a fire, the flames shall be kept outside of the door panel 30, thereby the fire is kept from spreading and penetration through the door panel 30.
  • Therefore, in case of a fire, flames could not reach through the surrounding margins of the door panel 30. Moreover, because of the upper rail 33, the lower rail 34, the left stile 35, the right stile 36 and the calcium silicate plates 40 all installed inside the door panel 30 to comprise a fire-resistant wall to resist heat, fire and deformation, the door panel 30 of this present invention has sufficient capability to resist fire, prevent flames from passing through the door panel 30, and avoid further spreading of the fire.
  • The foregoing fire-resistant structure of door panel 30 uses multiple layers of calcium silicate plate to form the surrounding margins of the door panel 30, with calcium silicate plates 40 directly embedded therein to comprise the inside lamination of the door panel 30. As shown in FIG 8, such a fire-resistant structure may be adopted in the installation of a door panel 30 equipped with the fixture of a glass window 50, a door panel 30 equipped with the fixture of a Venetian blind (not drawn in diagram), or a door panel 30 equipped with a handle reinforcement 55, to have the same performance of resisting flames from spreading and obstructing flames to pass through in case of a fire.
  • Furthermore, to increase decorative effects of the door panel 30, a piece of hardwood strip 37 as shown in FIG. 7 can be attached to the outermost side of the surrounding margins of the door panel 30, or, an additional protective coating 38 as shown in FIG. 7 can be pasted or painted on the surface of the hardwood strip 37 for better decorative effects.
  • As shown in FIGS. 3 to 8, in order to further reinforce the anti-bend structural strength of the door panel 30, a reinforcing iron plate 39 may be tightened to the innermost side of the surrounding margins of the door panel 30, for better anti-bend strength of the door panel 30.
