Schnürboden (shipbuilding)
In a shipyard, a large room or hall with a smooth floor, on which the construction plan of a ship was drawn in natural size, was referred to as a Schnürboden .
history
In the early days of shipbuilding, boats and ships were only created with the knowledge and skills of shipbuilders without drawings and fixed plans. With the introduction of iron and steel in shipbuilding, it was necessary to specialize and divide up the work of the shipyard employees in order to plan and prefabricate the individual parts of a ship. For this purpose, large weather-protected rooms or halls were created, which were called Schnürboden. With the development of shipbuilding halls, the attic of this hall could be used to record the curves of the frames , bulkheads and other parts in their original size from the information in the drawings . This floor is also called mall floor . The floor of the lace-up floor was carefully paved and painted. Good illumination of the cord floor was achieved through skylights. After all the important contours of the ship had been drawn or “untied” in their natural size, the outlines were transferred to wooden templates ( malls ). Their shape was recorded on the steel components and could then be made to fit exactly. Since the 1950s, the Schnürboden has been largely replaced by optical enlargement of very precise drawings, and since the mid-1960s by direct electronic control of the flame cutting machines. Today, ship constructions are developed with special shipbuilding CAD software.
