<p>The production method is for a floor module in a prefabricated wet room unit and involves a surrounding frame of metal plate extending in a height direction between a lower edge and an upper edge. A reinforcement network is fitted in a bottom area of the frame and is welded to the inside of the frame above the frame lower edge. A floor well is fitted in an opening in the reinforcement network and its outlet issues below the frame lower edge, so that the floor well inlet extends above the reinforcement network and its outlet issues below the lower edge of the frame. The frame with the reinforcement network and fitted floor well are placed above a cast plug which surface-wise fills the space inside the frame and in its upper side a part is formed which rises to a highest point in contact against the floor well inlet. Concrete is cast inside the frame to a level with the lower edge of the frame.</p> |
