<p>Formwork system comprising first and second plate means (21, 25, 26) which therebetween form a casting space (24) for concrete or the like, and which have a number of spacers (22, 23), at least one of said plate means and the spacers being adapted to be incorporated into a finished wall after casting. The first plate means comprise first plate element (21) having groove and tongue profiles (32) at least along the edges which are adapted to lie horizontally when mounted. The first plate elements have such thickness that the first plate means alone can stand with required stability. First spacer elements (22) are adapted to co-operate with the groove and tongue profiles and have coupling members (22A) adapted to project into the casting space (24). The second plate means comprise second plate elements (25, 26) having longitudinal edges adapted to lie horizontally and substantially level with said edges of the first plate elements (21). Second spacer elements are adapted to be anchored between said longitudinal edges of the second plate elements (25, 26) and to project into the casting space with coupling members (23A) shaped for interconnection with the coupling members (22A) on the first spacer elements (22).</p> |
