Definitions

  • the invention relates to a fire protection roller shutter with a roller shutter with two outer, spaced layers of sheet steel plates, between which at least one layer of insulating mats is arranged, and in which the joints between the sheet steel plates are formed on their longitudinal edges in the form of interlocking curved strips.
  • Double-armored roller doors (DE-B-16 59 775) designed as two-shaft systems with two roller doors arranged one behind the other with their own drive rollers are known (DE-B-23 49 026).
  • the roller shutters consist of sheet steel slats, between which at least one layer of insulating mats is arranged, and in which the joints between the sheet steel slats are formed on their longitudinal edges in the form of interlocking curved strips.
  • the invention has for its object to achieve practically the effect of a fire-resistant double armor system with a single-shaft system, which is suitable for all classes of approval.
  • the two outer layers of sheet steel slats are outer sections of a roller shutter, which consists of a continuous piece and with the help of a central section also formed from the sheet steel slats forms a closed double armor, which together with the at its Sections of inner insulating mats with one end in a known manner on the tubular shaft, with the other end attached to the ceiling, is wound on the shaft in the rest position and rests in the operating position with the middle section on the floor.
  • the fire protection roller shutter shown is a single-shaft system with a continuous armor attached to a tubular shaft 7 and to the ceiling 8, made of galvanized, approximately 1 mm thick steel sheet lamellae 1, on the longitudinal edges of which the joints in the form of interlocking curved strips in a manner known per se are integrally formed with mats 2 inserted on the inside and fastened only at both ends fire class A1 in 40 mm thickness.
  • two hanging armor sections 11 and 12 are formed, which are connected to one another by a lower section 13.
  • This lower piece 13 is e.g. riveted steel strip springs 3 made of spring steel 50 / 0.8, for example, are pressed straight and thereby presses the armored part 12 hanging loosely against stops 6.
  • This part 12 is approximately 30 mm overhanging at 5 on the ceiling 8 and is thereby pressed in the upper area.
  • the part 11 hanging on the shaft 7 is made 70 mm wider (35 mm on each side) and runs automatically in the provided guide grooves 4 when it is closed, whereby it is also pressed outwards against the guides 4 by the springs 3.
  • the steel sheet lamellae 1 of the three armor sections 11, 12, 13 can run curved in the same direction from the shaft 7 to the ceiling 8. However, as shown in FIGS. 1 and 3, the lamellae shown in the lateral sections 11 and 12 run in opposite directions from the shaft 7 or ceiling 8 and meet in the central section 13, where they are articulated by a C-shaped connector 10 are interconnected.
  • the usual camber 16, 17 can be made of concrete with a sliding plate cover or directly from sheet metal.
  • the side guides 4 consist of folded 3 mm thick steel sheet, can be inserted into each other by a bead-shaped bend and are only held by a front pressure screw connection.
  • FIG. 6 and 7 show how the slats of the sections 11 and 12 are attached to the mats 2 on the shaft 7 and ceiling 8. While the attachment to the ceiling 8 takes place by means of angle iron and screws, special hangers 15 are provided on the shaft 7 (cf. also FIG. 2).
  • a fire test with a simple mat filling for T 30 resulted in 70 min stability (30 min required) and with a mat doubled on the side armor sections 11 and 12 for T 90 110 min stability (90 min required).
  • this new fire protection roller door is also suitable for T 120 and above. All that is required is a suitable choice of the insulation spacing 9 between the hanging sections 11 and 12, as well as dimensioning and material selection for the mat fillings 2.
