<p>It comprises inner shuttering elements (11, 11') arranged between recoverable outer shuttering panels (1, 1') and delimiting a median cavity (12). These inner shuttering elements are kept apart from one another by locking members (13) which are in contact over their entire length with these inner elements and apply them against stops (7, 7') integral with the outer panels. The locking members have a cross-section such that it possesses at least two different diametral dimensions, and thus permit the release, by rotation about their longitudinal axis, of the inner shuttering elements, it being possible therefore to recover the latter. The median cavity formed in the wall realised after pouring the concrete is intended to receive, for example, an insulating material such as a polyurethane foam. <IMAGE></p> |
