For example, the fire door 30 has a plurality of dam beams 31 that can be arranged one above the other in the passage 7, wherein each dam beam 31 is positively engaged with its neighboring dam beam(s) 31 and sealed thereto. A wall profile 32 can be arranged in or on each side wall adjacent to the passage 7 or in or on a reveal on both sides of the passage 7, against which the fire door 30, in particular the dam beams 31, rests / rests towards the outside, so that the pressure of the cooling medium 10 and / or extinguishing medium 10 is introduced into the wall profiles 32. Furthermore, the wall profiles 32 and / or the fire protection gate 30, in particular the dam beams 31, can be provided with a vertical seal so that the cooling medium 10 and / or extinguishing medium 10 is held in the fire protection chamber 2.The wall profiles 32 can, for example, be designed as elongated, vertically arranged metal profiles, for example L-, H- or U-profiles.

[0043] The lowest dam beam 31 and / or the floor slab 4 in an area below the lowest dam beam 31 when the fire door 30 is closed can be provided with a horizontal seal so that the cooling medium 10 and / or extinguishing medium 10 cannot escape from the fire protection chamber 2 below the lowest dam beam 31.

[0044] Furthermore, a pressure bar 33 can be arranged on each side wall so as to be pivotable about a pivot point 34. The pivot point 34 is located in particular near the base plate 4, for example directly adjacent to the base plate 4. Furthermore, at least one actuator 35 is arranged for pivoting the pressure bar 33. When the fire protection door 30, in particular the dam beams 31, closes the passage 7, the pressure bar 33 can be pivoted about the pivot point 34 by means of the actuator 35 such that the fire protection door 30, in particular the dam beams 31, is pressed against the wall profile 32 by the pressure bar 33. To open the fire protection door 30, the pressure bar 33 can first be pivoted away from the fire protection door 30, in particular the dam beams 31, before the fire protection door 30, in particular the dam beams 31, are removed from the passage 7.

[0045] Furthermore, at least one actuator 36 can be provided for pressing the fire protection gate 30, in particular the dam beam 31, downwards against the horizontal seal.

[0046] Furthermore, a ceiling guide 37, in particular with an inlet curve 38, for guiding the fire protection door 30, in particular the dam beam 31, can be arranged below the ceiling plate 5.

[0047] Furthermore, at least one actuator 39 can be provided for moving the fire protection door 30, in particular the dam beam 31, from an open position lying below the ceiling plate 5 into a closed position in which the fire protection door 30 closes the passage 7, and in the opposite direction.

[0048] The dam beams 31 can be connected to one another by at least one dam beam belt 40 in order to be able to move them together between the open and the closed position and vice versa, wherein the dam beam belt 40 is attached to the dam beams 31 in such a way that they can come out of engagement with the adjacent dam beams 31 so that they can pass the inlet bend 38.

[0049] Fig. 4 is a further schematic view of the fire protection chamber 2, wherein the fire protection door 30 has been pushed from the open position along the ceiling guide 37, the inlet curve 38 and the open pressure bar 33 and rests against the floor with the lowest dam beam 31.

[0050] Fig. Figure 5 is a further schematic view of the fire protection chamber 2, wherein the pressure bar 33 has been pivoted toward the passage 7 by means of the actuator 35 in order to press the fire protection gate 30, in particular the dam beams 31, against the wall profile 32. Furthermore, the fire protection gate 30 is pressed from above against the horizontal seal by the actuator 36.

[0051] Fig. 6 is a schematic detailed view of the parking garage 20. In at least one of several levels 21.0, 21.1 to 21.7 of the parking garage 20, a plurality of vehicles 3 are parked on respective pallets 1, which can be displaced in a longitudinal direction and / or in a transverse direction via conveyor devices 17 within the levels 21.0 to 21.7.
