A sectional element for making an edge mould for a substantially horizontal plate, such as a balcony slab, has a vertical flange intended to form the edge of the mould, and a horizontal flange intended to form a mould part extending in underneath the edge portion of the plate. The distance between the top portion of the vertical flange and the horizontal flange defines the thickness of the plate. The sectional element consists of two separate sectional parts (1, 2) which can be joined together. One sectional part (1) has a vertical flange portion (3) forming the vertical flange, and first engagement means (7). The other section part (2) has a horizontal flange portion (5) forming the horizontal flange, and second engagement means (6) adapted, for joining together the two sectional parts (1, 2), to reversibly engage the first engagement means (7) in two different positions of engagement. The horizontal flange portion (5) and the second engagement means (6) are so unsymmetrically connected to each other that the distance defining the thickness of the plate is variable depending on which position of engagement the second engagement means (6) occupies when engaging the first engagement means (7). |
