Definitions

  • Such structural shapes are based upon compacted, previously slotted sections provided with folds acting as "hinges” which allow box-like sections to be pivoted to one another by hand so that they take a curved shape to be stiffened, however, by using a template or a rigid ribbing member screwed thereto to block the "hinges", thus preventing any swinging.
  • the present state of art provides other types of structural shapes that can be bent by hand about yielding notches and slots in the material. However, they also need stiffening templates to be secured thereto in their desired shapes.
  • the present industrial invention seeks to provide a method of manufacturing structural shapes and the structural shapes obtained therefrom that can easily be bent by hand and blocked in their final shapes by punching pliers, screws or other suitable fastening means without using templates or rigid ribbing members to block the bent sections in their desired shapes .
  • This object is achieved by slotting the flat starting band to form elongated and/or transversal slanting slots with a suitable pitch along with squeezed folds and orthogonal bends to provide a structural shape having the features described above.
  • the flat band is cut beforehand both by forming elongated slots and transversal slots inclined to the central axis . Further slotting to remove material away can also be provided to form suitable coupling recesses for snap-fitting further shapes.
  • the shaping of the cut band is made according to the previous slotting and the desired section of the structural shape.
  • the novel method of manufacturing structural shapes consists of three simultaneously coexisting mechanical methods of shaping structural shapes which will be described below in detail .
  • One mechanical method of the present invention allows a structural shape to be curved by weakening the material by slotting it with a defined pitch in the longitudinal direction so that the curved surface of the material is split up so as to come near to a continuous curved line.
  • Another mechanical method of the present invention causes surface portions of the structural shape to pivot to each other so as to be positioned in facing relationship and squeezed after a turnover of one surface portion by 180° with respect to the other surface portion.
  • Still another mechanical method of the present invention allows the structural shape to be self-blocked and stiffened by connecting the overturned opposite surface portions of the structural shape to each other by securing means such as punching or fastening screws .
  • the structural shape is rotated at the same time about an axis perpendicular to the plane of bending as well as the opposite slotted surface of the structural shape are caused to slip on each other, such surfaces being either partially connected to or completely separated from each other.
  • Fig. 1 of sheet I shows a band, preferably of metal, in which two rows of slanting notches are cut in the side edges of the band with a length about - as long as the width of the band;
  • Fig. 2 shows a squeezed band bent at the central axis
  • Fig. 3 shows the L-shaped structural shape obtained by bending the band of Fig. 2 at right angle in the middle;
  • Fig. 4 shows the cross section of the shape of Fig. 3;
  • Fig. 5 shows a curved, structural shape stiffened by fastening screws in a S-shaped configuration having both concave and convex bendings ;
  • Fig. 6 of sheet II shows a band, preferably of metal, in which Z- shaped slots with a defined pitch which are 2/3 as long as the length of the band are cut;
  • Fig. 7 shows the -shaped structural shape obtained by a double bending of the slotted band, the first one being a squeezed bending, the second one being a 90° bending, both bendings being 1/3 as wide as the width of the band;
  • Fig. 8 shows the cross section of the structural shape of Fig. 7;
  • Figs . 9 and 10 show the bent structural shape stiffened by fastening screws both in concave and convex curvatures .
  • Fig. 11 of sheet III shows a band, preferably of metal, provided with Z-shaped slots with a defined pitch formed centrally and being ⁇ as long as the width of the band;
  • Fig. 12 shows a T-shaped structural shape obtained by a squeezed bending at the central axis and two opposite bendings at 90°;
  • Fig. 13 shows an alternative embodiment of the T-shaped structural shape provided with a flat lining inserted thereon;
  • Fig. 14 shows the section of the structural shape of Fig. 12
  • Fig. 15 shows the bent structural shape of Fig. 13 and stiffened by fastening screws .
  • Fig. 16 of sheet IV shows a band, preferably of metal, having two parallel rows of Z-shaped slots with a defined pitch formed at the outer sides of the band so that the central portion equal to the half width of the band is not slotted;
  • Fig. 17 shows a structural shape obtained by bending the slotted portion to provide a U-shaped section, as shown in Fig. 18;
  • Fig. 19 shows a possible application of the structural shape as arch, in which supporting uprights for stiffening the carrying structure are provided;
  • Fig. 20 shows the details of such an arch.
  • Fig. 21 of sheet V shows a structural shape obtained from a band, preferably of metal, by slotting and shaping it in the form of " ⁇ ", as shown in Fig. 22;
  • Fig. 23 shows a curved structural shape stiffened by fastening screws, to which a further shape is snap-fitted, said structural shape being suspended to a hook and an adjusting spring;
  • Fig. 24 shows an application of the structural shape described above in a barrel vault .
  • Fig. 25 of sheet VI shows a particular T-shaped structural shape bent and stiffened by punching pliers and made by applying the method of forming T-shaped structural shapes according to the present invention, such structural shapes being shown both with concave and convex curvatures;
  • Fig. 26 shows the cross section of the T-shaped structural shape
  • Fig. 27 shows a particular embodiment of the notches to avoid the overlap of the surfaces when the structural shape is bent inside the slotted portion
  • Fig. 28 shows the structural shape of Fig. 3 having a slotted portion provided with a particular extensible band which allows the structural shape to be used as curved perimetrical member for finishing metal false ceilings, as shown in Fig. 29.
  • Figs. 30 to 39 of sheet VII show some sections of structural shapes to which the solutions of the present invention are applied.
  • the structural shape of Fig. 3 essentially consists of a band (1) , preferably of metal, provided with slanting slots (2) and (2') with a defined pitch parallel to one another and cut into the side edges of the band which is then bent and squeezed along its longitudinal axis (3) and further folded by 90° along axis (4) so that points (4') on the structural shape are the centres of the rotation axes (4") laying on the plane perpendicular to such axes which is also the plane of the notches of the opposite edges .
  • the bending is obtained by carrying out the methods described above as well as the stiffening and the blocking of the opposite surfaces to each other by fastening screws (5) .
  • the structural shape is even more stiffened with respect to the structural shape illustrated in Fig. 5 as the opposite surfaces are partially connected to each other by ridges (7") which prevent the surfaces of those portions of the structural shape from slipping.
  • a Z-shaped slotting is made centrally in a band (1") the side ends of which are not cut, the structural shape shown in Fig. 12 is obtained by a squeezed bending of the band along axis (8) and by bending the two ends by 90° in a divergent manner.
  • a lining shape (9) is inserted to such structural shape, as shown in Fig. 15.
  • Such structural shape finds application in round false ceilings of metal .
  • a Z-shaped slotting is made on both sides of a band (1"'), the central portion of which is not cut, and squeezed bendings are made along the longitudinal axes (10) and (10") by folding the material about the same surface of the band and then by bending by 90° along axes (10') and (10"), the structural shape shown in Fig. 17 which is bent and stiffened by fastening screws (5) or by punching (11) is obtained. Both blocking systems are valid as well as other systems achieving the same final object are applicable.
  • a possible application of the U-shaped structural shape described above is shown in Fig. 19 in a carrying structure of an arch in a wall, while Fig. 20 shows the U-shaped guide bent and stiffened, in which uprights (12) are inserted.
  • Fig. 23 shows a possible application both of the just described structural shape used as bent snap-fitted bar (18) and the bent perimetrical structural shape (18 ') already described and shown in Fig. 9.
  • a Z-shaped slotting is made on a structural shape for T-shaped structures commonly used for modular panels of false ceilings, a novel, interesting technical solution for a bent T-shaped structural shape shown in Fig. 25 is obtained.
  • Technical, functional, performance improvements of the structural shapes can be obtained by adjusting the thickness of the materials, the shape of the slots, and the blocking system.
  • Fig. 27 shows a notch (19) preventing the overlap of the material (20) during the "closed" bending
  • Fig. 28 shows a structural shape of the type of Fig. 3 which is lined by elastic PVC (21) and glued to the slotted surfaces (23) so as to allow such structural shape (24) to be used as bent perimetrical finishing members for false ceilings of metal, as shown in Fig.
