Definitions

  • the invention relates to a folding door with two door halves attached to a building, wherein the door halves have door leaves made of sheet steel articulated to one another by hinge connections.
  • folding gates are installed, for example, in buildings which are particularly to be protected, such as state criminal police or the like, the requirement arises to design the folding gates to be bullet-resistant.
  • a differentiation is made between different fire classes, whereby for example for fire class M 4 the folding door elements are provided with an 8 mm thick steel sheet and for fire class M 5 steel sheets with 13 mm thickness are provided. These steel sheets are sufficient to prevent conventional bullets from penetrating.
  • Weak points on such folding gates are the connections of the gate elements with the building opening, the divisions under the gate leaves and the center of the gate. Since a certain space must be left at these points to allow the movement of the parts, projectiles or projectile parts can pass through there.
  • DE-A-28 24 199 describes a device for connecting bulletproof glass to bulletproof composite panels on doors, windows and partitions, a catch chamber being formed between the pivotable glazing and the fixed part of the building in the closed state.
  • the invention has for its object to design a folding door in such a way that the bullet resistance is guaranteed everywhere.
  • trap chambers are provided at the connections to the building, at the branches and at the center of the gate, that the trap chambers are formed in the form of labyrinth arrangements from steel profiles and that the profiles on the gate side of the labyrinth arrangements are welded to the gate leaves.
  • an angle steel and on the top of the gate a steel bar lying in the closed state against the horizontal leg of the angle steel is arranged
  • an angle steel can be arranged be welded through one leg end and an elastic sealing strip can be arranged on the other leg end.
  • an angle profile can be arranged on the building side and a horizontally arranged steel strip on the building side, in particular in the case of a higher fire class as the upper connection, it being possible for a sealing strip lying against the steel strip to be provided on the angle profile.
  • a steel bar can preferably be anchored as the lower connection on the building side and a steel bar lying in the closed state against the steel bar can be arranged on the underside of the gate.
  • An elastic sealing strip can also be provided on the underside of the door.
  • a double-walled angle profile can be arranged in the corner recess of the wall as a side connection on the building side, a steel bar aligned parallel to the door can be attached to a leg and a T-shaped steel profile can be provided on the side surface of the door.
  • the legs of the T-profile can be connected to each other via an angle steel.
  • a sealing strip lying against the T-profile is preferably arranged, which can be clamped to the angle profile via an aluminum strip, the aluminum strip serving to absorb energy from ricochets due to the softness of the material.
  • the sealing strips serve to prevent bullet residues from passing through the gap without greater energy. Such remnants of the projectile are dampened and caught in the rubber profile.
  • a lining is arranged on the building-side angle profile, which can either consist of plastic and is attached to the angle profile and the building-side steel strip with aluminum profiles, or which can consist entirely of aluminum.
  • a lining also serves to absorb the energy from ricochets.
  • a steel bar can be arranged on each door wing in an embodiment of the invention and a steel bar projecting into the area of the other steel bar can be arranged on a steel bar.
  • a steel bar and a stop for the other steel bar can be arranged in the center of the door in each embodiment of the invention in the embodiment of the invention, an angular profile made of aluminum being arranged behind the double steel bar. It can further be provided that a seal is arranged between the door skin and the aluminum profile is, and that a sealing strip is clamped opposite the aluminum profile on an aluminum strip on the gate wing. These sealing strips and aluminum profiles also serve in particular to absorb the energy from ricochets.
  • the gate wings can have a frame made of steel tubes, the frame can be covered on both sides with a skin made of sheet steel and reinforcing plates made of steel can be arranged on the outside of the door on the inner wall of the steel skin.
  • the steel tubes can be square tubes, the steel skin can consist of a 3 mm thick steel sheet and, depending on the firing class, the reinforcement plates can be 8 or 13 mm thick, for example.
  • Sealing lips which preferably consist of rubber, can be provided in the area of the labyrinth arrangements.
  • layers for absorbing the energy from ricochets can be arranged in the labyrinth arrangements, which can consist of a synthetic rubber and / or an aluminum sheet and which are deformed when a projectile or part of a projectile hits, so as to absorb the kinetic energy of the projectile.
