Definitions

  • This invention relates to a method of fastening metallic members.
  • metallic members such as angles and support plates
  • carrier materials such as gypsum board, wood, chip board and the like
  • Netherlands patent application 7807256 describes a spiked metal plate for attachment to gypsum panels , in which the spikes are prevented from becoming loosened. This is only avoided, however, when the metal plate is loaded in one specific direction, while furthermore, a specially shaped metal plate is required with a weakened line, or score line, to produce the desired effect.
  • the invention provides a method of fastening metallic members in which a metallic member is placed with a planar portion thereof in contact with a carrier material, whereafter by means of a punch at least one tongue is liberated from the metal surface, which by moving the punch further downwards into said carrier material is bent to form a curved hook-shaped portion.
  • the invention also provides a punch for carrying out the method, which punch is elongated with a rectangular cross-section, there being provided a bevel on opposite sides of the longitudinal bottom of the punch at one end thereof, so that adjacent the bevels a portion of the bottom surface is maintained, the end face of the punch at said end being provided with a concave curvature extending from the bottom to the longitudinal top of the punch.
  • metallic members can be secured to a carrier material extremely firmly.
  • metallic members By adapting the force and velocity of stroke of the punch to the kind of carrier material, metallic members can be secured in a simple manner to both relatively soft material, such as gypsum board, and relatively hard material, such as cement-bonded chip board, with the metal plate being prevented from becoming detached by virtue of the hook-shaped curvature of the part bent from the metal plate.
  • relatively soft material such as gypsum board
  • relatively hard material such as cement-bonded chip board
  • Figures 1 and 2 respectively show, in top plan view and in side-elevational view, a metallic member 1 secured to a carrier material 2.
  • the metallic member is a corner- iron, but it is emphatically pointed out that the shape of the metallic member is completely irrelevant, so long as it has a planar portion to be secured to the carrier material.
  • the metallic member 1 is secured to the carrier material by means of hook-shaped portions 3.
  • the hook-shaped portions 3 have been formed by punching tongues from the material of the metallic member 1 by means of a punch 4, which tongues consist of tapered rectangular pieces.
  • the tongue members can be bent into hook-shaped members in the carrier material in the manner as shown, whereby an extremely firm connection is produced.
  • the connection is extremely strong when, as shown in the drawing, the hook-shaped portions are forced into the carrier material in opposite directions, so that loosening of the metallic members in the direction of stroke of the punch is not possible either.
  • more or fewer hook-shaped portions can be struck into the carrier material.
  • Figures 3 and 4 show a preferred embodiment of the punch in side and front elevational view, respectively.
  • Punch 4 is provided at its bottom, for a portion of its length, adjacent to its leading end, with a double bevel 5, 5', terminating at the bottom in a flattened portion 6 and at the front forming a dam 9.
  • the leading end is also provided with a curvature 7, 8, extending rearwardly from dam 9.
  • dam 9 has the shape of a trapezium with the short side of the trapezium being formed by the flattened portion 6.
  • the curvature 7, 8 has been formed from two circular arcs of circles having essentially the same radius R but with centers located at different levels. The distance between the centers is indicated by x in Fig. 3. This shape of the punch has turned out to be highly favourable to produce an optimal shape and curvature of the hook-shaped portions 3.
  • the punch is secured in a punching device known to those skilled in the art, and in which the stroke velocity and the impact force of the punch can be adjusted, while during the performance of the punch movement the metallic member is held down on to the carrier material.
  • a punching device known to those skilled in the art, and in which the stroke velocity and the impact force of the punch can be adjusted, while during the performance of the punch movement the metallic member is held down on to the carrier material.
  • some numerical values for the dimensions of the punch and the required stroke velocity and impact force for various carrier materials and a metallic member of steel sheet having a thickness of 1 mm to be fastened will be specified hereinafter by way of example.
  • the above values for the dimensions of the punch and the magnitudes of stroke velocity and impact force are given by way of example only and that the desired fastening of the metallic member to the carrier material can also be accomplished using punches having different dimensions and other kinds of metals, possibly with other thicknesses, and kinds of carrier material, using different stroke velocities and impact forces, and possibly using a different angle of stroke.
