Abstract

1314336 Shuttering for casting concrete JOHN LAING & SON Ltd 31 July 1970 [1 Aug 1969] 38754/69 Heading E1S A shutter for casting concrete walls is moulded from a lightweight thermoplastic or thermosetting resin and comprises a rectangular panel 10 having on its rear surface a peripheral flange 11 and intersecting reinforcement ribs 12-15 and 16-21, at least one rib (12 or 15 as shown) having a slot 22 to receive a tie bar which, in use, connects two opposed shutters, and having at each end a slot 25 extending parallel to the face of the panel to receive a reinforcing bar which extends along the edge of the panel. Adjacent shutters may be joined together by spring clips received in corresponding formations 27, each of which comprises an aperture in the flange 11 bounded by two abutments on the inside of the flange to prevent the clip from slipping. The tie bars are flat and each has a series of longitudinally spaced apertures; the ribs 12 and 15 are deeper than the other ribs and the flanges 11, and in the sides of each slot 22 are formed apertures which are aligned with a selected aperture in the tie bar and a wedge is inserted therethrough. In order that the shutter may be cut down, dummy slots 24 and dummy clip guides 27a are provided.
