Definitions

  • the present invention relates to a nail, in particular for connecting superstructures and substructures made of different or the same materials, such as e.g. for fastening superstructures made of various materials to substructures made of metal profiles.
  • Such nails are often used for example in prefabricated buildings, e.g. To fasten wooden panels to steel beams.
  • hardened steel nails are generally used when connecting superstructures to substructures made of comparatively hard material. These hardened nails can also be driven in with steel profiles. However, due to their hardening, these nails are extremely brittle and therefore only have a low elongation at break.
  • the fastening of wooden or chipboard to substructures made of steel profiles occurs e.g. due to temperature differences, tensions between the upper and the substructure, which cannot be compensated for by the shaft of the nail due to the low elongation at break of a hardened nail. This leads to breakage of the hardened nails.
  • the object of the present invention is therefore to propose a nail which is more suitable for the connection of upper structures and substructures made of different or the same materials.
  • a nail in particular for connecting upper structures and substructures made of different or identical materials, with a shaft and a tip connected to the shaft, the shaft of the nail covering an unhardened steel and the tip over a substantial part of its length of the nail has a hardened steel.
  • the aforementioned problem is therefore solved by a nail, the shaft of which is made of an unhardened steel, e.g. Carbon steel (C15 - C90), which is only hardened at the tip.
  • an unhardened steel e.g. Carbon steel (C15 - C90)
  • the hardened tip of the nail penetrates the substructure.
  • the uncured shaft of the nail is then anchored in the substructure, e.g. in a steel profile, and there is a firm connection between the upper structure and the substructure made of metal profiles.
  • This connection is flexible due to the non-hardened and therefore ductile shaft.
  • the shaft of the fastener can e.g. Catch expansion forces caused by temperature fluctuations. Due to the ductility of the shaft, there are no breaks and the connection between the upper and lower structures remains.
  • the nail of the present invention is therefore designed in such a way that after the nail has been driven in, the ductile shaft is anchored in the substructure. All static or dynamic forces and stresses occurring between the upper structure and the substructure are therefore absorbed solely by the ductile shaft of the nail.
  • the hardened tip of the nail is only used to form a passage when driving the nail in. Depending on the thickness of the substructure, after the nail has been driven in, the hardened tip of the nail is either completely in the substructure or it emerges from it. Since the hardened part of the nail is none The hardened part of the nail should be limited to the tip of the nail.
  • the shaft and the tip of the nail have a hardenable steel, the tip of the nail being hardened by heating.
  • the tip can be heated, for example, by flame curing or by induction.
  • the shaft of the nail can have a smooth, an annularly rolled or a helically rolled surface, or a combination of these surface shapes.
  • the grooves on the grooved surface of the shaft can be coated with e.g. microencapsulated adhesive.
  • a method for producing a nail in particular for connecting upper structures (18) and substructures (20) from different or similar materials, preferably the steps of producing a nail with a shaft and a tip connected to the shaft from a hardenable material , unhardened steel and hardening the tip of the nail by heating.
  • the nail described above is particularly suitable for fastening top and bottom structures made of different materials. Stresses that occur, for example, due to different thermal expansion of the upper and lower structures can be absorbed by the ductile shaft without the connection breaking. Because of the hardened tip, such nails can also be advantageously driven in using pneumatic nailing devices.
  • Fig.1 Different configurations of a nail with a hardened front
  • Superstructure on steel profiles. 1 shows various configurations of a nail according to the invention.
  • the nail 10 each has a head 12, a shaft 14 and a tip 16.
  • the head 12 and the substantial part of the length of the shaft are made of an unhardened carbon steel, while the tip 16 are made of hardened steel.
  • the shape of the shaft varies depending on the design.
  • the nail according to the invention can have a smooth shaft (Fig.1a)), a ring-shaped rolled shaft (Fig.1b)) or a screw shaft (Fig.1c)).
  • a combination of the different shaft shapes is possible.
  • an area of the shaft immediately adjacent to the tip may be hardened. Since only the unhardened area of the shaft enables a flexible connection between the upper and lower construction, this area is preferably made as large as possible, the length L2 correspondingly being as small as possible. Ideally, area L2 is limited to the tip of the nail, i.e. to the area that is particularly stressed when driving into a hard substructure.
  • the tip 16 is preferably hardened by heating the front region of the nail over the length L2. This can be flame curing, for example.
  • 2 shows the use of the nails according to the invention for connecting an upper structure 18, for example of wooden panels, on steel profiles 20.
  • the upper structure 18 rests on spacers 22 and is to be connected directly to the steel profile 20 underneath. This is done, for example, by driving the nails according to the invention using pneumatic nailing devices.
  • the hardened tip 16 of the nail penetrates the steel profile 20 lying under the upper structure 18 and thus enables the ductile part of the (annularly rolled) shaft 14 to be driven into the steel profile (see enlarged section from FIG. 2).
  • the shaft 14 of the nail 10 is then anchored in the steel profile, and there is a firm connection between the upper structure and the substructure. This connection is flexible due to the non-hardened and thus ductile part of the shaft 14 of the nail 10.
  • the shaft 14 of the fastening means can absorb the expansion forces which arise, for example, due to temperature fluctuations. Due to the ductility of the shaft, there are no breaks and the connection between the upper and lower structures remains permanent.
