Safety wall for a building

DETAILED DESCRIPTION It is accordingly an object of the invention to provide a wall, which overcomes the hereinafore-mentioned disadvantages of the heretofore-known devices of this general type and with which gas-tight sealing can be effected rapidly and reliably and with simple means.
The means to be employed for the sealing should in addition be reliably protected against mechanical or other actions.
In particular, reliable sealing of the wall should be ensured even when forces act on it.
With the foregoing and other objects in view there is provided, in accordance with the invention, a wall, particularly a wall of a containment for a nuclear plant, a pool or a cavern, comprising a bearing wall having surfaces; a sealing element covering at least one of the surfaces of the bearing wall; and a protective wall covering the sealing element; the protective wall being frictionally or force-lockingly connected to the bearing wall.
A force-locking connection is one which connects two elements together by force external to the elements, as opposed to a form-locking connection which is provided by the shapes of the elements themselves.
The sealing element seals the bearing wall gas-tightly and/or liquid-tightly.
The sealing element is protected by the protective wall against mechanical actions.
Such actions may be impinging parts, radiation, chemical actions or high temperature.
The protective wall does not need a foundation of its own, since it is fastened solely to the bearing wall.
Since this is a frictional connection, no relative displacement of the protective wall at right angles to the bearing wall can occur.
The sealing element is thus clamped between the bearing wall and the protective wall.
Detachment or loosening of the sealing element is impossible.
Since the protective wall is held by the bearing wall and thus rests on the same foundation, actions from the outside also cannot displace the protective wall relative to the bearing wall.
Actions from the outside cannot damage the sealing element
