<p>Method to manufacture a component part for a floor which in combination with several other component parts to compose a concrete floor, which floor (1) is provided on the downward facing surfaces with thermally insulating material as an encasing covering, and which composed concrete floor consists of a concrete slab (2) which is provided underneath with concrete ribs (3) at regular intervals, first an element (5) is cut out of a sheet (4) of thermally insulating material from a side of the sheet in the lengthwise direction, which element is L-shaped, one leg (7) of the L-shaped element (5) being formed from a part of the height of the side (6) of the sheet (4), in such a way that the end of the short leg (7) coincides with the underside (8) of the sheet (4), and the long leg (9) of the L-shaped element (5) being cut out of the inside of the sheet (4). Then the element (5) cut in an L-shape is taken out of the sheet (4), the element (5) cut in an L-shape is then placed in such a way that one leg (9) points upwards and the other leg (7) outwards, and in that the recess (10) of a sheet (4) is then placed on the upward pointing leg (9) that they form a shuttering, which shuttering is finally filled with concrete. So component parts which in cross-section are L-shape, U-shape, T-shape can be manufactured. <IMAGE></p> |
