THE PRESENT INVENTION RELATES TO A METHOD AND APPARATUS FOR PRODUCING A COMPOSITE STRUCTURE COMPRISING A SHEET METAL BOTTOM PLATE (6) AND A CONCRETE LAYER (18). THE UPPER SURFACE OF THE BOTTOM PLATE (6) IS PROVIDED WITH ANCHORS (15) FOR ANCHORAGE TO THE OVERLYING CONCRETE, AND THE CONCRETE LAYER (18) IS CAST OVER THE BOTTOM PLATE (60, AND THE CONCRETE LAYER (18) IS SHAPED BY TAKING IT THROUGH A BORDERED CASTING SPACE (1, 5, 10, 13) AND COMPACTING IT BY VIRTUE OF A VIBRATING MOTION APPLIED ON AT LEAST ONE FORM WALL OF THE CASTING SPACE, SAID MOVEMENT PROVIDING A VIBRATING AREA (7, 8) ON SAID CASTING SPACE. THE BOTTOM PLATE (6) IS PRECUT TO DIMENSIONS AND THE BOTTOM PLATE (6) THUS OBTAINED CORRESPONDING TO DESIGN OF THE COMPOSITE STRUCTURE BEING FABRICATED IS ACTUATED TO MOVE SUPPORTED BY A MOVABLE CASTING BED (1) THROUGH SAID CASTING SPACE (2-10) DURING CASTING, WHEREBY THE FRONT END OF SAID CONCRETE LAYER (18) IS BORDERED BY PLACING TO THE FRONT END OF SAID BOTTOM PLATE (6) AT LEAST IN THE BEGINNING OF THE CASTING STEP SUCH A FRONT WALL (11) WHICH IS MOVABLE ALONG WITH THE MOTION OF SAID BOTTOM PLATE (6) AT LEAST PARTIALLY THROUGH THE LENGTH OF SAID VIBRATING AREA (7, 8). THE REAR END OF SAID CONCRETE LAYER (180 IS FORMED WITH THE HELP OF A REAR WALL (12) BORDERING THE REAR END OF THE CASTING SPACE (7, 8), SAID REAR WELL BEING MOVABLE ALONG THE MOTION OF SAID BOTTOM PLATE (6) AT LEAST PARTIALLY THROUGH THE LENGTH OF SAID VIBRATING AREA (7, 8).
