Description

Nagel nail
Einleitungintroduction
Die vorliegende Erfindung betrifft einen Nagel, insbesondere zur Verbindung von Oberkonstruktionen und Unterkonstruktionen aus unterschiedlichen oder gleichen Materialien, wie z.B. zur Befestigung von Oberkonstruktionen aus verschiedensten Materialien auf Unterkonstruktionen aus Metallprofilen. Derartige Nägel werden beispielsweise im Bereich Fertigbau häufig eingesetzt um z.B. Holzpaneele an Stahlträgern zu befestigen.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.
Bei der Befestigung von Oberkonstruktionen aus den verschiedensten Materialien auf einer vergleichsweise harten Unterkonstruktion z.B. aus Metallprofilen, können ungehärtete Stahlnägel nicht verwendet werden. In der Tat lassen sich solche ungehärtete Stahlnägel wegen ihrer geringen Härte nicht durch die harte Unterkonstruktion treiben, so daß sich die Nägel verbiegen.When fastening superstructures made from a wide variety of materials to a comparatively hard substructure e.g. made of metal profiles, uncured steel nails cannot be used. In fact, such unhardened steel nails cannot be driven through the hard substructure because of their low hardness, so that the nails bend.
Aus diesem Grund werden bei Verbindungen von Oberkonstruktionen mit Unterkonstruktionen aus vergleichsweise hartem Material im allgemeinen gehärtete Stahlnägel eingesetzt. Diese gehärteten Nägel lassen sich auch durch Stahlprofile eintreiben. Diese Nägel sind allerdings aufgrund ihrer Härtung äußerst spröde und weisen daher nur eine geringe Bruchdehnung auf. Bei Verbindungen von gleichen oder verschiedenen Materialien wie z.B. der Befestigung von Holz- oder Spanplatten auf Unterkonstruktionen aus Stahlprofilen treten z.B. durch Temperaturunterschiede Spannungen zwischen der Ober- und der Unterkonstruktion auf, die wegen der geringen Bruchdehnung eines gehärteten Nagels von dem Schaft des Nagels nicht ausgeglichen werden können. Dies führt zu Brüchen der gehärteten Nägel.For this reason, 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. When connecting the same or different materials, e.g. 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.
Aufgabe der ErfindungObject of the invention
Aufgabe der vorliegenden Erfindung ist es folglich, einen Nagel vorzuschlagen, der sich für die Verbindung von Oberkonstruktionen und Unterkonstruktionen aus unterschiedlichen oder gleichen Materialien besser eignet. Allgemeine Beschreibung der ErfindungThe 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. General description of the invention
Diese Aufgabe wird erfindungsgemäß gelöst durch einen Nagel, insbesondere zur Verbindung von Oberkonstruktionen und Unterkonstruktionen aus unterschiedlichen oder gleichen Materialien, mit einem Schaft und einer mit dem Schaft verbundenen Spitze, wobei der Schaft des Nagels über einen wesentlichen Teil seiner Länge einen ungehärteten Stahl und die Spitze des Nagels einen gehärteten Stahl aufweist. Das genannte Problem wird demnach erfindungsgemäß durch einen Nagel gelöst, dessen Schaft aus einem ungehärteten Stahl, z.B. Kohlenstoffstahl (C15 - C90), besteht und der lediglich an der Spitze gehärtet ist. Beim Eintreiben des erfindungsgemäßen Nagels in eine vergleichsweise harte Unterkonstruktion z.B. mit pneumatischen Nagelgeräten, durchdringt die gehärtete Spitze des Nagels die Unterkonstruktion. Der ungehärtete Schaft des Nagels verankert sich daraufhin in der Unterkonstruktion, z.B. in einem Stahlprofil, und es entsteht eine feste Verbindung zwischen der Oberkonstruktion und der Unterkonstruktion aus Metallprofilen.This object is achieved according to the invention by means of 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. According to the invention, 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. When driving the nail according to the invention into a comparatively hard substructure e.g. With pneumatic nailers, 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.
Diese Verbindung ist durch den nicht gehärteten und somit duktilen Schaft flexibel. Der Schaft des Befestigungsmittels kann die z.B. durch Temperaturschwankungen entstehenden Dehnungskräfte auffangen. Bedingt durch die Duktilität des Schaftes entstehen keine Brüche und die Verbindung zwischen Oberkonstruktion und Unterkonstruktion bleibt bestehen.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.
Der Nagel der vorliegenden Erfindung ist demnach derart ausgestaltet, dass nach dem Eintreiben des Nagels, der duktile Schaft in der Unterkonstruktion verankert ist. Alle zwischen der Oberkonstruktion und der Unterkonstruktion auftretenden, statischen oder dynamischen Kräfte und Beanspruchungen werden demnach alleine von dem duktilen Schaft des Nagels aufgenommen. Die gehärtete Spitze des Nagels dient lediglich zum Formen eines Durchtrittskanals beim Eintreiben des Nagels. Abhängig von der Dicke der Unterkonstruktion, steckt die gehärtete Spitze des Nagels nach dem Eintreiben des Nagels entweder vollständig in der Unterkonstruktion oder sie tritt aus dieser wieder hervor. Da der gehärtete Teil des Nagels keine Befestigungsfunktion zwischen der Ober- und der Unterkonstruktion übernehmen soll, sollte sich der gehärtete Teil des Nagels lediglich auf die Spitze des Nagels beschränken.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.
In einer bevorzugten Ausgestaltung der Erfindung weisen der Schaft und die Spitze des Nagels einen härtbaren Stahl auf, wobei die Spitze des Nagels durch Erwärmen gehärtet ist. Das Erwärmen der Spitze kann dabei beispielsweise mittels einer Flammhärtung oder durch Induktion erfolgen.In a preferred embodiment of the invention, 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.
Der Schaft des Nagels kann eine glatte, eine ringförmig gerollte oder eine schraubenförmig gerollte Oberfläche aufweisen bzw. eine Kombination aus diesen Oberflächenformen.The shaft of the nail can have a smooth, an annularly rolled or a helically rolled surface, or a combination of these surface shapes.
Zwecks Erhöhung der Ausziehwerte können die Rillen der gerillten Oberfläche des Schaftes mit einem z.B. mikroverkapselten Klebstoff versehen werden.In order to increase the pull-out values, the grooves on the grooved surface of the shaft can be coated with e.g. microencapsulated adhesive.
Es ist anzumerken, daß ein Verfahren zum Herstellen eines Nagels, insbesondere zur Verbindung von Oberkonstruktionen (18) und Unterkonstruktionen (20) aus unterschiedlichen oder gleichartigen Materialien, vorzugsweise die Schritte Herstellen eines Nagels mit einem Schaft und einer mit dem Schaft verbundenen Spitze aus einem härtbaren, ungehärteten Stahl und Härten der Spitze des Nagels durch Erwärmen aufweist.It should be noted that 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.
Es ist anzumerken, dass sich der oben beschriebene Nagel besonders gut zue Befestigung von Ober- und Unterkonstruktionen aus unterschiedlichen Materialien eignet. Spannungen, die beispielsweise aufgrund unterschiedlicher thermischer Ausdehnung von Ober- und Unterkonstruktion auftreten, können von dem duktilen Schaft aufgenommen werden, ohne dass die Verbindung bricht. Aufgrund der gehärteten Spitze lassen sich derartige Nägel darüber hinaus vorteilhaft mittels pneumatischer Nagelgeräte eintreiben.It should be noted that 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.
Beschreibung anhand der FigurenDescription based on the figures
Im folgenden wird eine Ausgestaltung der Erfindung anhand der beiliegenden Figuren beschrieben. Es zeigen: Fig.1 : Verschiedene Ausgestaltungen eines Nagels mit gehärtetem vorderenAn embodiment of the invention is described below with reference to the accompanying figures. Show it: Fig.1: Different configurations of a nail with a hardened front

Oberkonstruktion auf Stahlprofilen. In der Fig. 1 sind verschiedene Ausgestaltungen eines erfindungsgemäßen Nagels dargestellt. Der Nagel 10 weist jeweils einen Kopf 12, einen Schaft 14 und eine Spitze 16 auf. Der Kopf 12 und der wesentliche Teil der Länge des Schaftes bestehen aus einem ungehärteten Kohlenstoffstahl, während die Spitze 16 aus gehärtetem Stahl bestehen. Die Schaftform ist je nach Ausgestaltung unterschiedlich. So kann der erfindungsgemäße Nagel einen glatten Schaft (Fig.1a)), einen ringförmig gerollten Schaft (Fig.1b)) oder einen Schraubschaft (Fig.1c)) aufweisen. Alternativ ist auch eine Kombination der verschiedenen Schaftformen möglich.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. Thus, 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)). Alternatively, a combination of the different shaft shapes is possible.
Bei der Härtung der Spitze des Nagels kann gegebenenfalls ein unmittelbar an die Spitze angrenzender Bereich des Schaftes eine Härtung erfahren. Da nur der ungehärtete Bereich des Schaftes eine flexible Verbindung zwischen Ober- und Unterkonstruktion ermöglicht, ist dieser Bereich vorzugsweise möglichst groß ausgestaltet, wobei entsprechend die Länge L2 möglichst klein ist. Im Idealfall beschränkt sich der Bereich L2 lediglich auf die Spitze des Nagels, d.h. auf den Bereich der beim Eintreiben in eine harte Unterkonstruktion besonders beansprucht wird.During the hardening of the tip of the nail, 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.
Das Härten der Spitze 16 erfolgt vorzugsweise durch Erwärmung des vorderen Bereichs des Nagels auf der Länge L2. Hierbei kann es sich beispielsweise um eine Flammhärtung handeln. In Fig.2 ist die Verwendung der erfindungsgemäßen Nägel zur Verbindung einer Oberkonstruktion 18, z.B. von Holzpaneelen, auf Stahlprofilen 20 dargestellt. Die Oberkonstruktion 18 liegt auf Abstandhaltern 22 auf und soll direkt mit dem darunterliegenden Stahlprofil 20 verbunden werden. Dies erfolgt beispielsweise durch Eintreiben der erfindungsgemäßen Nägel mittels pneumatischer Nagelgeräte. Die gehärtete Spitze 16 des Nagel durchdringt das unter der Oberkonstruktion 18 liegende Stahlprofil 20 und ermöglicht somit ein Eintreiben des duktilen Teils des (ringförmig gerollten) Schaftes 14 bis in das Stahlprofil (siehe vergrößerten Ausschnitt aus Fig.2). Der Schaft 14 des Nagels 10 verankert sich daraufhin in dem Stahlprofil, und es entsteht eine feste Verbindung zwischen der Oberkonstruktion und der Unterkonstruktion. Diese Verbindung ist durch den nicht gehärteten und somit duktilen Teil des Schafts 14 des Nagels 10 flexibel. Der Schaft 14 des Befestigungsmittels kann die z.B. durch Temperaturschwankungen entstehenden Dehnungskräfte auffangen. Bedingt durch die Duktilität des Schaftes entstehen keine Brüche und die Verbindung zwischen Oberkonstruktion und Unterkonstruktion bleibt dauerhaft bestehen. 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.
