Definitions

  • the present invention relates to a teaching adjustable by means of screw clamps from profile elements, which are connected by means of tabs, for determining the bending curves for ship's outer profiles.
  • a ship's hull is made from individual extruded profiles which engage in a tongue-and-groove manner and are screwed together by means of flanges and screwed to one another and to the transverse chip skeleton.
  • the determination of the bending curve (saber), which is different for each profile according to the trunk curvature, is the task for the present invention. It is known that an adjustable gauge, which consists of profile elements, which are adjustably connected to one another by tabs and with screws are noticeable and still have movable needles to use for the precise removal of the contour of a car body, but this device is not applicable for the above-mentioned purpose, where the longitudinal curve (saber) of a particular profile with different flange thickness, which is obtained by a different bending behavior, must be determined.
  • FIG. 1 shows the jig attached to a hull under construction for removing the bending profile
  • Fig. 2 shows a section of the jig in elevation
  • Fig. 3 in cross-section, along the line A / a of Fig. 2.
  • Fig. 4 shows the cross section of FIG. 1st
  • the teaching 1 consists of a plurality of profile sections 2 of the same profile as it is used for the ship's skin 3, so that it fits into the profiles 3 and can be easily inserted into one another.
  • These sections 2 are connected to one another by tabs 4 with screws 5, the screw holes being so large or oblong holes that there is an angular adjustability.
  • the profile sections 2 are chamfered at the corners 6. The process is now as follows:
  • the gauge 1 It is first placed the gauge 1 with loosened screws 5 on the transverse chip skeleton 7 and bent so that it lies on the entire length. Then the screws 5 are tightened and thus fix the curvature.
  • the gauge 1 is now removed and placed either on the floor or on the bending machine, the curvature is measured and transferred to the stop blocks of the bending machine and thus this is then adjusted. Then the corresponding hull outer profile 3 is bent and mounted on the transverse span skeleton 7. Now the gauge 1 is used again and is placed on the assembled outer hull profile 3, thus determining the shape of the next outer hull profile 3 until the hull is finished.
  • the long flanges 8 are cut to the width of the other flanges (FIG. 4) on the profile sections 2 of the gauge 1, which come into contact with the transverse ribs 7 that a smaller width is created by this flange height, which causes a greater inclination of the gauge than it would correspond to the ship's cross-section when mooring and tightening with screw clamp 9 or the like (FIGS. 1 and 4). This marks a lower saber curve than it would correspond to the fuselage.
