Definitions

  • the present door frame is for being mounted in an opening in a wall and includes fixing elements attachable to the walls and a frame portion adapted to fit a door or the like and connected to said fixing elements.
  • the present invention is concerned with a door frame especially to be used in fire door assemblies, and preferably to be manufactured to steel sections, which frame is designed to be placed within the opening of a wall and comprises a portion, which is provided with a stop edge, which is adapted to fit the intended shutting element, a door or the like, whereby said portion constitutes a separate arrangement.
  • the frame furthermore comprises a number of fixing elements, which are arranged to be fixed preferably along two edges of the opening of the wall provided for the frame, and fitting into said opening, with said portion and the fixing elements being arranged to be connected with each other in such divergent positions inbetween them that said fitting to the shutting element and opening of the wall respectively is maintained after jointing the assembly.
  • Said door frame is especially well fitted to be used in fire door assemblies, but it can also be used for other types of door or for scuttles and windows.
  • the frame is designed to be manufactured of steel sections.
  • the frame When the last-mentioned method is used, as is preferably the case in cast concrete walls, whereby the frame enters into the casting mould assembly, other inconveniences present themselves, viz the frames have to be available at a very early stage of construction, the frame has to be separated from the element, which belongs to it, e.g. the door, which involves risks of mistakes and there may also arise difficulties in the fitting work and further the frame may easily be damaged, when the wall is constructed.
  • Said object is obtained by designing the frame so that the fixing element is a plane perpendicular to the opening of the wall in the intended position for mounting has a cross section, which is widening, preferably stepwise, in a direction towards one of the wall sides, and that said portion of the frame designed to cooperate with the shutting element at least at its outwards-facing sides, which are designed to cooperate with the fixing elements has a corresponding stepped cross section so that when the fixing elements are mounted in the opening of the wall, said portion of the frame can be pushed to the desired mounting position relative to the fixing elements from one side the opening.
  • FIGS. l-S illustrate an embodiment for concrete or brick walls, in which FIG. I is a horizontal cross section through the side members of the frame,
  • FIGS. 2 and 3 are cross-sectional views of corner coverings for the frame
  • FIG. 4 is a view of a comer
  • FIG. 5 is a vertical cross section of a threshold.
  • FIGS. 6 to 8 illustrate a second embodiment designed preferably for steel walls and walls of plaster slabs, in which FIG. 6 is a horizontal cross section through the side member of the frame,
  • FIG. 8 is a side elevational view of the frame.
  • the basic idea of the invention is the portion of the frame, which is arranged to support a door panel or the like, for example, hinges to be fitted to the frame in a conventional manner and be provided .with a stop edge against said frame and be able to be locked, not being placed directly within the opening of the wall, but being fastened to a number of long fixing elements, which have been mounted in the opening of the wall before the final insertion of the first said portion of the frame.
  • Said fixing elements which closely follow the wall ir respective of its tolerances, can be mounted to said portion of the frame in different positions, so that thereby an adaptation can be made between the opening of the wall and said portion of the frame.
  • FIG. I in which the numeral I indicates a cast opening in. a wall.
  • a fixing element 3 has been fastened.
  • the frame portion indicated by the numeral 4 has a hinge 5 and'a stop edge 6 and is in its turn fastened to the fixing element 3 by means of rivets 7, which can be riveted from the outside of the frame.
  • a suitable type of rivet being the socalled explosion rivet.
  • the cavity ofthe interior of the frame is suit ably filled wit some insulating material 8, such as rock wool by way of example.
  • the fixing element 3 thus presents a stepped shape with a first portion 3c extending in the direction towards the opening of the wall, and adjacent thereto a portion 4a located at a right angle to the plane of the wall, and further, a portion 3b pointing in a direction outwards and away from the wall.
  • the side 4b of the frame 4 which side also is pointing in a direction out wards and away from the wall, is fixed.
  • the threshold 9 of the frame is illustrated, which threshold is resting on the floor 13 with projections 28 and is fixed to a lower fixing element 10 by means of driving pins or self-threading screws 11 and 12.
  • the fixing element 10 is fixed to the floor 13 by means of steel nails 14.
  • the frames 6 and 9, respectively, must be dimensioned according to the measurements of the door and in order to make it possible to fix said frame to the fixing elements in spite of the fact that said elements 3 and possibly also 10 may occupy different positions due to the great tolerances of the dimensions of the opening of the wall, the holes for the rivets 7 and possibly also the screws 11 and 12 are suitably bored simultaneously in the same operation.
  • the corners of the portion 4 of the frame and/or the fixing elements can be jointed by special cover plates and mouldings 29 and 30 as per FIGS. 2 and 3, by means of which the corner joint is covered as seen in FIG. 4.
  • the frame according to the second embodiment is designed to be mounted on walls, which are built up of slabs 31 and 32 fastened to crossbars 20.
  • a fixing element 22 by means of rivets 21 is fastened to the crossbar 20, in this particular case a steel section, and carries the side members 23 of the frame. These members are fastened to the fixing elements 22 by means of rivets 24.
  • a so-called shadow moulding 25 is fastened, which shall cover the junction between the slab 32 and he fixing element 22.
  • the connecting upper part 26, see FIG. 7, of the frame at the top is supported by the side members 23 of the frame and is not fixed to the wall by any special fixing element. Also here there is a shadow moulding 27.
  • the shadow mouldings 25 and 27 may be mitered and welded together.
  • portion 4, and 23, 26, respectively, of the frame When mounting the portion 4, and 23, 26, respectively, of the frame it can be ready made and include side members, connecting header at the top, bottom portion, and threshold, jointed together by means of welding to form one integral unit. However, it can also be delivered in separate parts and be joined together in connection with the placing within the opening, by way of example using corner jointing elements.
  • a frame according to the invention which thus comprises an ordinary frame as well as fixing elements belonging thereto, a mounting with a good fit can be obtained in an opening of a wall, which is already built up, without the building itself having to be affected by any complicating working operations.
