Patent DE-4212225-A1 (DE)
Title: Gas=tight multi layer containment wall for nuclear installations - comprising supporting wall, covering sealing layer and outer protective wall, fastened firmly to the supporting wall
Inventor: DANISCH RUEDIGER DIPL ING
IPC: G21C13/00
Filed: 1992-04-13
Abstract: A containment wall for a nuclear installation, for example, a cave or tent. It comprises a sealing layer (4) arranged to cover a supporting wall (2) and over this a covering protective wall (5). The protective wall (5) is locked together with the support wall (2) by means of bolts (6, 8) which pass through the sealing layer (4) from the protective wall (5) and are anchored in the support wall (2). The sealing layer (4) has a gas tight seal to the anchor bolts (6, 8). Further it is firmly attached to the support wall (2) and or the protective wall (5) by means of an adhesive. The protective wall (5) is made up of components (5a-5f) which are attached firmly to the support wall and also interlock with each other. USE/ADVANTAGE - The wall is intended for use in nuclear containment constructions. It is especially useful when walls of an already constructed building are to have protective and sealing layers fixed retrospectively to them. This can then be achieved quickly, reliably and relatively cheaply. The wall protects against radiation, chemical effects and high temperatures. As the protective wall is attached to the support wall, only one foundation is needed and movement between the two (as would be the case in 2 separate walls) is avoided.

Title: Device for a floor shuttering
Inventor: DINGLER GERHARD
IPC: E04G11/48
Filed: 1993-03-18
Abstract: A support for a floor shuttering has a support head with an upwardly open groove, in which at least one engagement profile, e.g. a shuttering-panel element, can be inserted such that it is secured against unintentional removal by means of its hook edge. For this purpose, movable locking bars (59, 61, 62, 63) are mounted on the support head, which locking bars move outwards when the engagement profile is fitted in and, in the operating position of the engagement profile, grip over the hook edge thereof. A counterweight to the locking bar means that the latter is retained in the locking position and can be pivoted back manually. In contrast to gripover edges formed rigidly on the support head, securing by means of locking bars offers the advantage that the shuttering-panel element does not have to be pivoted for fitting it in or detaching it, which pivoting operation may cause problems in certain situations. <IMAGE>
