Definitions

  • the present invention relates to a roof hook magazine for a nail setter, formed from several detachably connected magazin convinced roof hooks, each having a shaft, at one end of a receptacle for holding roofing or facade panels, slate slabs in particular is arranged on a roof surface, and at the another end region is formed an impact tip arranged at an angle to the shaft.
  • roof hooks for the attachment of roof or facade panels.
  • slates are fastened by means of such roof hooks on facades or roofing on a roof surface.
  • the use of roof hooks has become established, because with this type of attachment slate shingles need not be pierced for attachment with a nail and so even in case of storm stress no deflection of the bore hole is to be feared by a fixing nail.
  • the slate shingles of the roof hook has to mostly on one side to the shank of the roof hook angled impact tip and at the other free end of a recording, for example in the form of a clip.
  • a first roof hook is nailed over the impact tip with a hammer into the respective roof battens on the roof surface.
  • a second roof hook is then introduced into the roof batten to secure the slate to be mounted.
  • the slate to be mounted is suspended in the bracket of the roof hook and fixed therein.
  • roof hooks are at least partially glued together to form the roof hook strip on a polymeric binder or adhesive.
  • the roof hooks forming roof hooks have a nearly maximum packing density, since they are arranged substantially touching each other and bonded together. This ensures that the same size and thus manageability of the setting tool latter can be equipped with a much higher number of roof hooks per magazine and thus a reloading of the magazine of the setting device can be done at a much later date. This improves the speed of the roofer and thus effectively reduces the cost of roofing a roof while improving worker safety.
  • the roof hook strip according to the invention can advantageously be formed of stainless steel or bending wire as possible, in particular of AlSi 430 or AlSi 304 1.4301 X5CRM18-10.
  • a tensile strength of between 500 and 2000 N / mm 2 preferably a tensile strength of between 70 and 900 N / mm 2, may be preferred.
  • roof hooks are made of a bending wire, it is possible to first generate the mold in a conventional manner in a bending machine and to align it in the connection to one another and to glue it together via the polymeric binder or the adhesive. It is no longer necessary, the roof hooks manufacture in a complex injection molding process with the insertion of a reinforcing wire.
  • the bonding of the roof hooks may be appropriate for the bonding of the roof hooks to wrap only the tip with the polymeric binder or adhesive.
  • a particularly reliable connection of the roof hooks to a roof hook strip is given when the polymeric binder is formed by a contact adhesive, in particular a glue coating, which in particular has good adhesion properties on metal surfaces.
  • roof hooks are made of a different material, then it is of course also possible to modify the polymeric binder or the adhesive so that its adhesion properties are optimally matched to the surface of the roof hooks. This may be necessary if the roof hook is provided, for example, as a corrosion protection with a coating.
  • the polymeric binders used in the present invention may be selected from polyacrylates, polyvinyl chlorides, polyurethanes, polyamides, polyesters, alkyd resins, polyvinyl acetates, Polybutadienstyrolen, polyvinylidene, polychloroprenes, rubbers, maleates, polyolefins, epoxies, silicones, silane-terminated polymers, in particular silane-terminated polyurethanes , Polyamides and polyoxyalkylenes, and their co- and terpolymers or mixtures of these.
  • the polymeric binder or adhesive may further include a solvent.
  • a solvent for this example, water or an organic solvent such as acetone, methyl ethyl ketone, ethyl acetate, aromatic hydrocarbons such as toluene or xylene, aliphatic hydrocarbons such as hexane or heptane, halogenated hydrocarbons, or mixtures of these come into question.
  • the polymeric binder contains no solvent, but is a reactive system.
  • cyanoacrylates or silicone or silane prepolymers come into question as well as 1-K or 2-K polyurethane precursors or other mixtures, which result in a polymerization reaction, the polymeric binder mentioned above.
  • the polymeric binder or the adhesive contains at least one additive.
  • This can be selected from tackifiers, adhesion promoters, plasticizers, corrosion inhibitors, stabilizers, dispersing aids, dyes, pigments or mixtures of these.
  • Particularly advantageous of the aforementioned additives is the use of tackifiers, for example in the form of tackifying resins such as rosin or rosin derivatives. The advantage is that the tackifiers improve the tackiness and the cohesion of the polymeric binder and thereby more firmly anchor the packing contained therein in driving the roof hook into a substrate on the surface of the roof hook.
  • the Ausziehhong the roof hooks can be increased by certain types of packing in a particularly advantageous manner. It is advantageous, however, in any case, that the polymeric binder together with packing in the region of the shank of the impact tip is applied.
  • the extraction values of roof hooks can be increased especially by spherical or hemispherical packing in a special way.
  • Preferred embodiments of the roof hook according to the invention therefore consists in that the packing at least partially have a spherical or hemispherical shape and are in particular selected from hollow plastic microspheres, plastic microspheres, hollow glass microspheres, glass microspheres, ceramic microspheres or ceramic hollow microspheres or mixtures of these, wherein the composition is preferably applied in the region of the shank of the impact tip.
  • the polymeric binder comprises from 2 to 80% by volume of fillers, based on the amount of filler used, in particular from 5 to 70% by volume, preferably from 7 to 60% by volume. It has been found that compositions having such levels of packing have a particularly advantageous effect on increasing the pullout values of the fasteners coated with such compositions. Thus, this effect is already at relatively low levels of the aforementioned packing and increases with increasing amount of filler.
  • the aforementioned packing contents relate to the volume fraction of packing in the form of the bulk volume before it is mixed, for example, with the polymeric binder composition.
  • composition of the invention a variety of different packing can be used, such as particulate, layered or fibrous packing and mixtures of the aforementioned packing.
  • the particulate fillers may be of organic or inorganic origin.
  • Particularly suitable packing of the aforementioned type are, for example, silica particles, such as fumed silica or precipitated silica, glass foam particles, sand, clay, chalk, gypsum, talc, glass, ceramics, wood plastic, in particular polyvinyl chloride, or mixtures of the aforementioned packing.
  • the particulate fillers may be irregular in shape or, for certain applications, may have a spherical or hemispherical shape.
  • microspheres, open or closed hollow microspheres, as well as mixtures thereof are preferred.
  • ceramic microspheres, plastic microspheres or glass microspheres and the respective hollow microspheres in question are preferred.
  • Such a method for producing a roof nail strip according to the invention can be carried out for example with a conventional bending machine, wherein the bending machine is extended with a Magazin michs- and gluing unit over the prior art.
  • the roof hooks are first ejected from the bending machine so that they are arranged parallel to each other as possible touching each other in a unit for storing a DachhakenstMails parallel to each other.
  • a bending machine makes it possible to produce roof hooks of different lengths by simple programming, in particular to produce roof hooks with a length of between 50 and 200 mm, preferably between 70 and 120 mm.
  • the roof hook strip thus formed can be used in setting tools and then driven for example via a pneumatic piston from the setting tool in the wood of the roof frame ,
  • FIG. 1 a roof hook 1 according to the prior art is shown.
  • the roof hook 1 has a shank 2, on whose one end region a receptacle 3 for holding roof or facade panels is formed.
  • the other end area the roof hook 1 is provided with an impact tip 4 arranged at an angle to the shaft 2.
  • the receptacle 3 is shown here in the form of a bent hook.
  • the receptacle is formed so that it conforms to the edge region of the roof or facade panels and in particular has a projection which engages in a formed in the facade or roof plate groove, so as to prevent unwanted slippage of the roof or facade panel, for example, counteract the occurrence of external forces such as by storm.
  • FIG. 2 shows a roof hook strip 5 according to the invention, which consists of several with each other via a polymeric binder or adhesive lacquer releasably connected magazin convinced roof hook 1 from FIG. 1 is formed.
  • the impact tips 3 are coated with the polymeric binder.
  • the polymeric binder is applied here in the form of a Klebelacks in liquid form on the impact tips. After a short time, the adhesive coat solidifies and hardens, which leads to a bonding of the roof hooks 1 with each other.
