DESCRIPTION:

BRIEF SUMMARY
The present invention refers to a large-scale container which is preferably transportable and closable by a fireproof sliding door in accordance with the preamble of claim 1.
Large-scale containers of this type which store inflammable materials and have an entrance opening closable by a sliding door encounter sealing problems in the area of the ceiling-side guidance of the leaves in case of fire, that is when there is a danger of fire penetrating from outside into the large-scale container, so that heat penetrating into the interior of the large-scale container may ignite the easily inflammable materials stored therein.
The present invention is based upon the object to create a large-scale container of this type in such a manner that the sliding door is optimally sealed in a fireproof manner with respect to the large-scale container.
This object is attained in accordance with the present invention by the features set forth in the characterizing part of claim 1.
These constructive measures effectively avoid in the upper area of the guidance a penetration of heat from outside into the interior of the large-scale container, with the insulant-forming layers, which are known per se, expanding upon contact by heat in order to seal an otherwise existing passage between the leaves, on the one hand, and the fireproof bulkhead, on the other hand.
In any event, the time required by hot air to pass the mentioned passage is longer than the reaction time of the insulant-forming layers.
In accordance with an advantageous embodiment of the invention, the leaves are each provided in the overlapping area in closing position thereof with overlapping elbow-shaped brackets which are provided with insulant-forming layers as well.
In this manner, a labyrinth-type passageway is created which is closed by the insulant-forming layers upon contact by heat so that a fireproof seal is obtained also in this area.
Moreover, the essentially form-fitting joint between both leaves substantially avoids a distortion thereof during heat impact so that the operativeness of the sliding door is maintained.
According to a further feature of the invention, a barrier is arranged also in the bottom area between and parallel to both leaves which acts like a fireproof bulkhead and is provided with insulant-forming layers along the sides thereof facing the leaves.
Also in this case, a fireproof seal is created which contributes to optimize the fire protection behavior of the sliding door.
Further advantageous features of the invention are set forth in the dependent claims.
An exemplified embodiment of the invention will now be described with reference to the attached drawings in which
FIG. 1 shows a partial longitudinal section through a large-scale container in the area of the sliding door,
FIG. 2 shows a partial cross sectional view through the large-scale container also in the area of the sliding door,
FIG. 3 shows a partial section of a leaf in the corner area for suspension from the ceiling.
FIG. 1 shows a large-scale container 7 having a ceiling 8 which is provided with two parallel guide rails 12 spaced from each other at a distance for slidably supporting two leaves 1, 2 of a sliding door by means of rollers 13.
The leaves 1, 2 are provided with cranked suspensions 15, with their free end face supporting the rollers 13 which run in the guide rails 12.
Further mounted to the ceiling 8 is a fireproof bulkhead 10 which is positioned between the spaced leaves 1, 2, extends over the entire width of the sliding door and projects into the space between the leaves 1, 2.
The sides of the leaves 1, 2 facing the bulkhead 10 as well as the sides of the bulkhead 10 facing the leaves 1, 2 are provided with a fireproof intumescent coating (insulant forming layers) 14 which has a volume expanding during fire i.e. at increase of the ambient temperature to thereby completely fill the existing space between the fireproof bulkhead 10 and the respective leaves 1, 2 so that a penetration of heat into the interior of the large-scale container is prevented.
