Definitions

  • the purpose of the present invention is to provide a corrugated sheet made of metal or other deformable but shape rigid material which i.a. is adapted for use in a shell as referred to above and wherein the folds or waves are arranged in such a manner that when the sheet is in the form a generally flat condition or in a curved condition having a radius of curvature which is very great as compared with the amplitude value of the corrugations, no essential tensile stress is developed in the sheet along the plane so formed.
  • this is achieved by so forming the corrugations that they consist of substantially straight wave crests departing in opposite directions from the mean plane of the sheet, the individual wave crests being so arranged relatively to each other that the crests departing in one direction are broken by crests extending at an angle, preferably right angles, to the first mentioned crest and that the length of the curve measured along the surface of the sheet between any two parallel planes extending at a right angle to the said mean plane, is always essentially the same when measured along two sectional lines in two further parallel planes extending at right angles to the mean plane and at right angles to the first mentioned two planes.
  • the individual corrugations may be formed in the most varying manners.
  • the wave crests may be flattened at the top and this top may be of a very short length along the crest, to such a degree that the wave crest may even present itself in approximately nipple form.
  • the wave crests extending at right Patented Aug. 10, 1965 angles relatively to each other may be positioned at different distances from the mean plane of the sheet, and they may be of different width at the top and/or they may have different side slope angles.
  • the half wave length i.e. the distance between the wave crest tops in a direction at right angles to the direction of length of the crests may differ. All such various features will be of influence to the properties which are characteristic to each individual sheet, and the choice of this or that particular feature will depend upon the material used as well as upon the intended use of the sheet.
  • FIGURE 1 is a perspective view of the sheet.
  • FIGURE 2 is a sectional view taken along the line A-A of FIGURE 1.
  • FIGURE 3 is a sectional view taken along the line BB of FIGURE 1.
  • a sheet formed material is formed with a plurality of mutually parallel wave crests 1 of short length and transversely to the same a plurality of series of crests 2 of short length and lesser height than the former.
  • the sheet of the example is formed with a slightly S formed profile of the hill sides of the crests 1, so as to give marked wave tops 11 and valley bottoms 12, whereas the hill sides of the crests 2 are approximately rectilinear, in sectional view.
  • Such a double corrugated sheet is capable of absorbing tensile and compressive forces along the mean plane of the sheet, independently of the direction of such forces relatively to the direction of length of the individual wave crests, without thereby giving rise to any noticeable marginal tensions or tensions in the sheet as a whole.
  • a corrugated sheet made from a flattened sheet of deformable material having three sets of corrugations therein, the corrugations of each set being substantially parallel, the corrugations of the first set extending alternately in opposite directions from the mean plane of said material with wave crests equi-distant from the mean plane of said material, said second and third sets of corrugations being parallel to each other and at an angle with respect to said first set of corrugations, the corrugations of said second and third sets being spaced from each other and extending alternately inwardly from said wave crests in said first set of corrugations onopposite sides of said mean plane respectively, the distance of the wave crests of said second and third sets of corrugations from said mean planebeing less than the distance of the wave crests of said first setof corrugations from the mean plane, all of said corrugations being formed without elongation of said material, whereby when said sheet is subjected to tensile and compression forces along its mean plane the angles of said corrugations will vary without altering
  • said second and third sets of corrugations are at right angles to said first set of corrugations.
