Definitions

  • the invention relates to a steel-structured door, comprising a steel door frame, a refractory thermal insulation, and a door panel on either face, said door panels making up external sides of the door.
  • Steel-structured doors are typically used for applications in which the door is employed for constructing a compartment retarding or stopping the spread of fire in a building.
  • Such typical applications include, among others, doors in shopping centers and office buildings between emergency exit staircases and other business premises or other space, doors between parking garages and exits, and so forth.
  • the rate of using a door can often be remarkably high, the door being thus subjected to numerous applications of load over the course of a day.
  • the in-door fire resistant thermal insulation employed in prior art fire rated steel doors comprises fire protection insulation based on mineral wool, such as PAROC FPS 14, ISOVER PKOL or the like.
  • the construction of a fire door set forth in the present invention provides for a steel-structured fire door, which complies with said new, more stringent regulations and enables its thickness to be substantially maintained within the conventional fire door thickness range.
  • the thermal insulation set inside a fire door of the invention comprises an insulation layer made from a gypsum material, the vaporization of crystal water present in said gypsum material in fire situation resisting effectively the transfer of heat through the door.
  • the layer of gypsum material can be made for example by cutting from a ready-to-use board of gypsum material, such as a building board composed of a gypsum material.
  • the layer of gypsum material can be made for example by casting the gypsum material to its position inside the door.
  • the solution according to the invention is not limited just to steel-structured fire doors, but it can be used advantageously also in other steel-structured door designs.
  • the door according to the invention is characterized by what is presented in the characterizing part of claim 1.
  • the applied directions relevant to the construction will be as follows.
  • the X-direction represents a longitudinal direction of the construction, hence for example a vertical direction of the door.
  • the Y-direction represents a lateral direction of the doorway opening. Consequently, the XY-plane is substantially the same as a direction of the door plane.
  • the Z-direction is a thickness or depth direction. As this invention is particularly concerned with the thermal engineering aspects of structural elements, the Z-direction is also generally consistent with the temperature gradient direction of an installed structure in the event of a fire.
  • a fire door 1 shown in fig. 1 comprises a steel door frame 2, a door panel 3 on either face of the door 1, and a refractory thermal insulation set inside the door frame 2 and the door panels 3, said thermal insulation being depicted more precisely in the subsequent figures.
  • Figs. 2 and 3 illustrate more accurately the internal fire door construction of the invention in cross-sectional views.
  • the refractory thermal insulation set in a space defined by the door frame 2 and the door panels 3 of the door 1 consists, in the illustrated embodiment, of mineral wool layers 4, as well as an unbroken gypsum material layer 5 interposed therebetween.
  • the gypsum material layer 5 is positioned in the internal space of a door in such a way that the gypsum material layer has its face in a substantially parallel relationship with the door panels 3 of the door 1. In addition, the gypsum material layer 5 substantially fills the space defined by the door frame in an XY-plane.
  • the gypsum material layer 5 is secured in place inside the door 1 by means of brace blocks 6, said brace blocks being attached to the door frame 2 and/or the door panels 3.
  • the brace blocks 6 are preferably made from steel hollow profile.
  • the gypsum material layer 5 can be made for example by cutting from a ready-to-use gypsum material board, such as from a building board of gypsum material.
  • the gypsum material layer 5 can be made for example by casting the gypsum material to its position inside the door 1.
  • the door frame is preferably made from steel profile, having its interior filled with mineral wool.
  • the door frame 2 has its steel profile provided with heat discontinuities, said heat discontinuities retarding the propagation of heat in a Z-direction across the door.
  • the door panels 3 are preferably manufactured in steel sheet. Attachment of the door panels 3 to the door frame 2 can be carried out for example by welding, a screw attachment and/or gluing.
  • the useful mineral wool in a solution of the invention is for example PAROC FPS 14, ISOVER PKOL or the like fire resistant mineral wool.
  • Fig. 4 shows diagrammatically the results of a fire test performed on a fire door construction of the invention. This particular fire test was conducted in a gas furnace, in which the door construction of the invention had been positioned to close the combustion chamber.
  • a line A represents, as a function of time, the average temperature rise measured at several measuring points in coincidence with the brace block 6 on the external surface of a door construction according to the invention.
  • a line B represents, as a function of time, the average temperature rise measured at several measuring points in coincidence with the refractory thermal insulation on the external surface of a door construction according to the invention.
  • a line C represents, as a function of time, the average temperature rise measured at several measuring points in coincidence with the door frame 2 on the external surface of a door construction according to the invention.
  • the temperature rise in coincidence with the refractory thermal insulation as represented by the line B, climbs in about 35 minutes to about 100°C, which temperature remains unchanged to the point of about 65 minutes, after which the temperature begins to rise further.
  • the initial temperature of the fire test is the normal room temperature, i.e. about 20°C.
  • This substantially flat section of the line B depicted in fig. 4 at the temperature of about 100° between time points of about 35 minutes and about 65 minutes and thereby representing the temperature of a fire door's external surface in coincidence with the refractory thermal insulation, results from the fact that crystal water, which is contained in the gypsum material layer 5 present in the thermal insulation, is escaping from the gypsum material.
  • This escape of crystal water by evaporation has a cooling effect on the thermal insulation and maintains it at a steady temperature until the evaporation of crystal water from the gypsum material is complete.
  • the relatively steep temperature rise at the time point of about 67 minutes along the line B represents a situation in which all of the crystal water has evaporated from the gypsum material, allowing the gypsum material temperature to rise again.
