<p>A formwork frame comprising a rectangular/polygonal circumferential frame may, using relatively small dimensions, be utilized as a cavity-forming frame to be place within a formwork/casting mould or, using relatively large dimensions, as a formwork/casting mould. The circumferential frame comprises loose intermediate pieces (10a-10d) to be jointed together with loose corner pieces (12a-12d). The corner pieces (12a-12d) and the end portions of the intermediate pieces (10a-10d) are provided with cooperating connecting means which are interlocked by means of external locking means in the form of wedges (14). The corner pieces (12a-12d) and the end pieces of the intermediate pieces (10a-10d) are provided with sloping faces for resting supportingly against each other. The connecting means of the corner pieces consist of fixed bolt means (possibly through-going bores for such bolt means) and the end portions of the intermediate pieces are formed with bores for said bolt means. Each of the bolt means is provided with a through-going lateral hole for one of said wedges (14).</p> |
