  • the invention relates to a fastening arrangement, a screw for a fastening arrangement and a use of a screw in a fastening arrangement.
  • the screw connection consists of a screw 150, a washer 152 and a nut 154 which is screwed onto the screw 150.
  • This example shows two such compounds of screw 150, washer 152 and nut 154. Washers may also be provided on the head side and head and mother side.
  • the component 1 12, as in the present case is a hollow profile, it is to be provided with a mounting opening 156 through which it can pass, or through which a tool can be passed. In this way, the screw 150 can be inserted through the mounting holes provided in the components 1 12, 1 14 from one side, while the washer 152 and the nut 154 are attached from the other side.
  • Such mounting arrangements 1 10 are subject to disadvantages. It is necessary to provide a mounting opening 156, so subject the hollow sections further manufacturing steps. In addition, the mounting apertures 156 weaken the fastener assembly and thus the entire structure associated with the fastener assembly 10. Furthermore, the fitter must work with two hands if he wants to attach the screw 150, 152, 154. From one side, the screw 150 must be inserted through openings of the components 1 12, 1 14 with one hand, while from the other side, washer 152 and nut 154 must be attached with the other hand. The requirement of mounting holes not only increases the manufacturing cost, but, with the same stability, the weight of the entire component construction. From DE 10 2007 004 970 A1 a thread-forming screw with a trilobular thread section is known. The screw is suitable for screwing into components with a core bore, in particular for light metal parts or components with a large screw-in depth.
  • DE 10 2004 034 246 B4 describes a screw for fastening two components together. With this screw succeeds a non-cutting production of a nut thread in one of the components to be joined together.
  • the DE 10 201 1 087 683 A1 discloses a screw that forms itself a thread in a parent component.
  • US 4,057,295 discloses container walls which are held together by bolts and nuts.
  • a fastening arrangement with at least one first component and at least one second component, at least one screw for fastening the components to each other, wherein the screw is formed as a thread-forming screw and a thread-carrying, a screw axis defining shaft and a head has, wherein the Screw is screwed into already prepared before a screwing Einschraubö Anlagenen the components and wherein during the screwing at least in the first component, a thread is formed, wherein the second component is such that the head during the entire screwing by applying force applying means is reached, and wherein the first component is a hollow profile, which is such that in the region of its screw-in opening no mounting opening for attaching a fastening means is provided by a second component not facing side of the first component, so that s one the components cohesive, acting in the direction of the screw axis force is generated exclusively by the first component contacting thread and the second component contacting head.
  • the aforementioned mounting opening "in the area" of the screw-in opening of the first component is to be understood as an opening in the component, which allows convenient access to the screw-in opening.
  • mounting openings are thus, for example, not any openings offset from the screw-in openings, through which the screw-in opening can be accessed only with the greatest effort.
  • the fastening arrangement can be produced much faster than a fastening arrangement of the prior art, since only the screw-in openings of the components have to be brought over one another, whereupon the thread-forming screw is simply screwed in from one side.
  • the other hand does not need to guide a nut, but it can, if necessary, affect or correct the alignment of the components relative to each other.
  • the fastening arrangement is part of a truss, a building-carrying shelf, a container or a static steel structure.
  • Such constructions can be of a very large scale, with a very large number of components to be connected together.
  • the advantages of the invention come into play especially, because on the basis of the invention, the constructions are much faster to produce than in the prior art. Furthermore, weight saving and saving on production costs play an even greater role, the greater the designs to be produced.
  • the fastening arrangement consists of metal.
  • the shank of the screw has a search tip. Since during assembly the screw-in opening of the first component can be covered by the second component, it is advisable to equip the screw with such a tip, which easily finds the screw-in opening of the first component.
  • the screw tapers away from the screw head and ends in a flattened or even a non-flattened search tip.
  • the shank of the screw has a threadless portion at its head end. This is to ensure that the thread of the screw in the assembled state is no longer in engagement with the second component, but rather that the screw can rotate freely in the second component by means of the unthreaded portion. This makes it possible to press the components together by the action of thread and screw head.
  • the thread in cross-section is at least partially out of round, in particular trilobular. Due to the high flank coverage of this thread form, a form-fitting connection between the screw and in particular the first component is achieved. This is an important prerequisite, especially for thin sheets, in order to be able to absorb high axial tensile forces.
  • At least one thread groove, notch, groove or the like is arranged on a thread-carrying shaft portion as a reverse rotation.
  • the boundaries of the groove act as engaging elements and thus contribute to anchoring the engaging at least in the first component thread.
  • a locking or stop toothing is attached to a head underside, which faces the second component. This also prevents inadvertent turning back of the screw.
  • the production cost of the components to be joined is to be reduced, it should be possible to provide designs with lower weight with the same stability and the assembly effort is to be reduced.
  • the invention relates to a fastening arrangement with at least one first component and at least one second component, at least one screw for fastening the components to each other, wherein the screw is designed as a thread-forming screw and a thread-carrying, a screw axis defining shaft and a Head has, wherein the screw is screwed into already prepared before a screwing Einschraubö Anlagenen the components and wherein during the screwing at least in the first component, a thread is formed and wherein at least a portion of the thread of the screw, a nut or sleeve is screwed.
  • the present invention provides mounting arrangements of high stability, it may be desirable in a particular case to nevertheless select a mounting arrangement of the conventional type, that is to say a screw in combination with a nut. Then it is useful if the thread-forming screw has a portion to which a nut is screwed. The installer can then decide during assembly, whether he wants to select this conventional type of connection in exceptional cases. In order to ensure the Aufschraubbarkeit the nut or the sleeve, these components may be equipped with internal threads that match a corresponding male threaded portion of the screw. It is also conceivable to use nuts or sleeves that have no internal thread. In this case, use is made of the thread-forming property of the screw.

It is also possible to unscrew a nut or sleeve without thread only on the protruding from the first component screw when the screw is finally positioned.
  • the force required to additionally position a nut or sleeve on the screw can be varied by providing nuts or sleeves with different inner diameters or different materials, at least in the area in which the thread is to be formed, be used.
