The present invention relates to an arrangement in an arch enclosure (1), which is designed in the casting of an arch to constitute a mould for the arch essentially incorporated in an outer wall element. The invention is characterised in that the arrangement comprises a sheet metal profile generally with a horizontal U-shape. One leg (2) of this is designed to be placed on an upper boundary surface (3a) of a lower wall element (3) covering this. The other leg (8) has a width which represents a small proportion of the width of the said one leg (2). There is an intermediate section (7) adjoining the legs (2, 8), the width of which section is equal to the thickness of the arch. Between the said legs (2; 8) there are also stiffening elements (9, 10a, 10b) designed to prevent the legs (2, 8) being brough closer together or further apart by more than a predetermined amount. |
