Definitions

  • the invention relates to a fire door made of a box-shaped, an insulating plate enclosing door leaf in which a stiffening profile covering an end face of the insulating plate is arranged.
  • the width of the stiffening profile extends over the Thickness of the insulating plate, the stiffening profile to the end faces and / or to At least one open groove is defined inside the door leaf.
  • a fire door which is in the plate-shaped door leaf contains a frame which is formed from a profile which is in the plane of the Angled longitudinal edge strips pointing towards the inside of the door leaf and is equipped with a groove open to the sides of the door leaf.
  • a fire door is characterized by a special high stability without being heavy.
  • a box-shaped fire protection door enclosing an insulating plate is used
  • Door leaf in which an end face of the insulating plate overlapping Stiffening profile is arranged, which is angled towards the inside of the door leaf Longitudinal edge strips, a groove open towards the front of the door leaf and itself Has stiffening beads extending in the longitudinal direction of the profile.
  • the width of the stiffening profile extends over the thickness of the insulating plate and the stiffening beads at substantially even intervals across the width of the stiffening profile are distributed.
  • the width of the stiffening profile over this known design the thickness of the insulating plate extends, there is a significant weight reduction in that the groove open towards the end faces of the door leaf is only very small Depth can be carried out because the bending and torsional rigidity of the Stiffening profile by distributing the stiffening beads over the width of the Stiffening profile is improved.
  • the previously described known fire door in the profile forming the stiffening frame stiffening beads only provided in the soffits of the groove.
  • the invention is therefore based on the object of proposing a fire protection door, which is distinguished by a fire door known from DE 44 09 720 A1 characterized by improved dimensional stability, although it is inexpensive to manufacture and for the manufacture of the stiffening profile a negligible additional material required.
  • the invention achieves this Stiffening profile through the two laterally arranged pleat packs extraordinarily improved stiffening, especially since the fold gaps in the level of the door leaf are aligned and the depth of the folds is at least twice the Thickness of the steel strip corresponds.
  • Such a fold formation gives the stiffening profile despite a restriction of the folds to the two profile edge areas higher bending stiffness than a stiffening profile, stiffening beads distributed over its full width are arranged. Every fold in the stiffening profile causes a deflection of the steel strip material by 180 °, which means an additional one in the deflection areas The steel strip material is strengthened by corresponding structural changes.
  • Each fold package therefore forms a highly resistant area of the stiffening profile and thus increases the dimensional stability of a door leaf for a fire protection door extraordinary.
  • outer edge strips of the stiffening profile angled in mirror image and form a fold package facing each other underpinning thighs.
  • each pleat package with additional stiffening a smooth finish to the inside of the door, whereas the front faces the Can fully support the insulating plate. This is achieved in particular by the fact that preferably each inn of the outer edge strips at least over the base a fold package extends.
  • a further embodiment of the invention provides that in a middle piece of the stiffening profile forming the groove bottom at intervals its length distributed, weld bosses directed towards the end faces of the door leaf are.
  • the fire door consists of a box-shaped door leaf 1, which consists of two cover plates 2 and 3 is composed and contains an insulating plate 4.
  • FIG. 1 An upper horizontal end face of the insulating plate 4 is, as shown in Figure 1, by a Stiffening profile 5 covered.
  • Figures 2 and 3 illustrate that as well the two vertical end faces of the insulating plate 4 are covered by a stiffening profile 5 are.
  • the stiffening profile 5 is on the lock side of the door leaf 1 with a rectangular Opening 6 for a lock case 7 and on the hinge side of the door leaf 1 provided with a bore 8 for a threaded bolt 9 of a locking pin 10. While a lock faceplate 11 is inserted into the relevant end face of the door leaf 1 is, the threaded bolt 9 of the locking pin 10 in the threaded bore a base plate 12 held inside the door leaf 1.
  • the stiffening profile 5 consists of a Steel strip that can be hot-dip galvanized for corrosion protection reasons.
  • the steel strip is shaped into a stiffening profile 5 that both Long sides of a middle flat steel strip center piece 13 each in a semicircular shape pass over curved connecting strip 14.
  • On every connecting strip 14 is followed by a fold package 15. While the steel strip center piece 13 defines a groove bottom, form the mutually facing inner sides of the fold packs 15 groove reveals.
  • the depth of columns 16 and 17 corresponds twice the thickness of the steel strip, from which the stiffening profile 5 is made is.
  • Outer edge strips 18 of the stiffening profile 5 are angled in mirror image and form oppositely directed legs 19, which each fold package 15th undertake.
  • the stiffening profile 5 shown in FIG. 5 differs from the previously described stiffening profile 5 shown in Figure 4 only in that a fold package with only triple material overlap on both sides of the profile is formed, whereas in the exemplary embodiment according to FIG. 4 each pleat packet is one has five times the material overlap.
  • the stiffening profile 5 shown in FIG. 6 differs from that according to FIG 4 only in that the angled outer edge strips 18 with their opposing Thighs 19 meet.
  • the exemplary embodiment according to FIG. 7 shows one that corresponds to FIG Stiffening profile 5, but in the steel strip center piece 13 at intervals above it Warts 20 pointing to the end faces of the door leaf 1 are distributed in length are. The warts 20 lighten due to their direct contact with the inner surfaces the front of the door leaf 1 spot weld connections between the Stiffening profile 5 and the cover plate 2.
