Definitions

  • the invention relates to a fastener and a fastening system for plates, in particular composite panels, which are preferably to be fixed to the outside of buildings.
  • Metal composite panels as typical examples of composite panels usually consist of a plastic core, which is planked on both sides with thin metal plates. Instead of the metal plates, another composite material harder than the core can be used in other composite plate systems. In particular, it is also conceivable to produce plates with a multilayer structure made of plastic. A problem with the attachment of such plates is that the connection between the plastic core and the surface-forming materials is often difficult. For attachment of such plates, it is therefore common to provide the plate with a through hole and then to screw. However, such fittings are not unproblematic, especially on the outside of buildings. In addition to the optical impairment is here in particular the lack of tightness of the outside to call, as at the screw head and through the through hole water can penetrate behind the composite plate.
  • a fastener which consists of a base plate and a threaded pin.
  • a holding element which in contrast to Base plate, which is circular in plan view, is elongated. The total length of the retaining element is greater than the diameter of the base plate.
  • an undercut recess is introduced in the composite plate. The section which is open to the surface corresponds in its diameter substantially to the diameter of the base plate.
  • the cutout has two opposite radial extensions, so that in this area the holding element can be used. By turning the retaining element it then engages behind at least the plate into which the cutout is made.
  • a disadvantage of the described embodiment is that only in the region of the ends of the holding element, which protrude beyond the base plate, a power transmission from the fastening element to the composite plate is possible. Especially with composite materials where the connection between the cover plate and the plastic core is relatively poor, but this is problematic. The force is applied over a too small surface area. Deformation of the cover plate and possibly tearing off the plastic core is therefore possible. From the FR1 099 003 A a fastener is known in which a plurality of retaining elements are pressed radially apart when the fastener is mounted. However, the fastening element has a large height in relation to its diameter and is hardly usable in thin plates. It is therefore the object of the invention to provide an improved fastening solution.
  • the fastening element according to claim 1 and the corresponding fastening system has a pin for attachment to a plate holder.
  • a pin may for example be a threaded pin which is fixed to a base plate of the fastener.
  • An attachment of the pin to the base plate can be done for example by welding.
  • On the base plate a plurality of retaining elements can be fixed.
  • the plurality of retaining elements is a distribution of the force with which the composite plate is fixed to a plate holder, such as a facade of a building, possible.
  • the plurality of retaining elements can be distributed over the circumference of the base plate. The selective introduction of force in the composite plate can thus be prevented.
  • the holding elements on a flat bearing area and a relative to this support area angled section.
  • the angled section is oriented so that it is at planar concern of the support area of the Has retaining elements on the base plate of the pin for attachment points away.
  • the angled area protrudes beyond the outer edge of the baseplate.
  • holding elements which essentially correspond to a circle segment
  • a transmission of force can take place over almost the entire circumference of, for example, a circular base plate.
  • the surface is therefore considerably larger than the known fastening system.
  • the plurality of retaining elements which allow, for example, a transmission of force over almost the entire circumference of the base plate, connected to each other via a plastically formable connection.
  • a plastic moldable connection it is possible to connect only one of the holding elements fixed to the base plate. This considerably simplifies the assembly work.
  • the region of the transition forms the plastically deformable connection in the region of the transition between the support region and the angled section of the holding elements by a web.
  • the retaining elements By bending the retaining elements are not only pressed radially outward by the action of a tensile force on the pin, but also the support area held flat on the base plate.
  • the connection between the fixedly secured to the base plate holding element and the adjacent holding elements thus serves only for mounting. Subsequently, the holding elements are fixed by the forces occurring in terms of their position anyway.
  • FIG. 1 the overall system 1 for fastening a composite panel is shown.
  • the composite plate 2 has in a known manner, for example, two directed towards the outer sides of metal plates which are interconnected by a plastic core.
  • a cutout 10 is introduced.
  • the cutout is, for example, in a plan view of the in the FIG. 1 left cover plate circular.
  • the cutout 10 has an undercut and does not extend over the entire thickness of the composite plate 2.
  • the cutout has the geometry of a truncated cone in the plate cross-section.
  • a fastening element 3 is provided for fixing the composite plate 2 to a plate holder, for example metal profiles on an outer wall of a building.
  • the fastening element 3 has a threaded pin 4.
  • threaded pin 4 instead of the threaded pin 4, of course, other preferably pin-shaped elements are provided with which the frictional connection to the plate holder is possible.
  • the illustrated threaded pin 4 is fixed to a base plate 5 of the fastener 3.
  • the attachment is preferably by welding, so as to allow a mass production inexpensively.
  • the diameter of the preferably substantially circular base plate 5 is chosen so that it is smaller than the opening diameter of the cutout 10 to the surface of the composite plate 2 out.
  • On the base plate 5 are also distributed over the circumference of the base plate arranged, a plurality of holding elements 6, 6 'is provided. These holding elements 6, 6 'have a support region 7, 7', and a chamfered section 8, 8 '.
  • the chamfered portion 8, 8 ' is angled relative to the support area 7, 7' preferably at 45 ° angle.
  • the outwardly directed surface of the angled region 8, 8 'thus abuts against the wall of the cutout 10.
  • FIG. 1 a solution is shown in which a plurality of holding elements 6, 6 'are connected to each other.
  • the holding elements 6 to fix all holding elements 6, 6 'of the fastening element 3, only one of the holding elements 6 to be firmly connected to the base plate 5.
  • this is realized by a screw.
  • the one, firmly connected holding element 6 can be welded to the base plate 5, for example by spot welding.
  • the holding element 6, which is screwed to the base plate 5, shows that the angle between the support area 7 and the angled portion 8 is just in one position, so that the chamfered area 8 projects beyond the base plate 5.
  • the total height of the fastening element 3, that is to say the thickness of the base plate 5 plus the thickness of the bearing regions 7, 7 ', is selected such that its height corresponds to the milling depth of the cutout 10.
  • the oriented in the direction of the free end of the pin 4 surface of the support areas 7, 7 ' is flush with the surface of the composite panel 2.
  • FIG. 2 1 shows a plan view from the side of the threaded pin 4 on a total of three holding elements 6, 6 ', 6 "It can be seen that the holding element 6 is provided with a bore via which a screwing of the holding element 6 with the base plate 5 is possible
  • a second holding element 6 ' is connected to the holding element 6, which is firmly fastened to the base plate 5.
  • a web 9 serves for the connection, which in the region of the transition between the support region 7 and the angled section 8 of the holding element 6 and the support region 7 'and the angled section 8' of the second holding element 6 'is formed.
  • the web 9 is plastically deformable FIG.
  • the third retaining element 6 " is connected to the retaining element 6 via a second web 9 '.
  • the third retaining element 6" is twisted so that it is erected in the direction of the free end of the threaded pin 4.
  • the two upright ends of the holding element 6 'and of the holding element 6 "which are remote from the holding element 6 are then lowered into the cutout 10, so that the webs 9, 9' are plastically deformed the retaining elements 6 'and 6 "in the cutout can be done mounting the plate 2.
  • FIG. 3 shows a plan view of a base plate 5 of the fastener 3.
  • the threaded pin 4 by welding attached.
  • a receptacle for the screw is also provided in the base plate 5 and designated 11.
  • the thread 11 for receiving the screw is provided in a region of the base plate 5 with a first diameter.
  • the base plate 5 On the opposite side, but over less than half of the circumference, the base plate 5 has a smaller radius. In this way, the insertion of the preassembled fastener 3 is facilitated in the cutout 10.
  • a chamfer 12 or 12' is formed in the base plate 5.
  • This chamfer 12, 12 ' runs so that the erected during pre-assembly holding elements 6' and 6 "can be pushed with their angled portions 8 ', 8" along this chamfer into the cutout 10.
  • the bevel 12 or 12' does not extend to the area of the reduced diameter of the base plate 5 Bevel 12 and 12 'and the beginning of the reduced diameter portion of the base plate 5, a portion which in the assembled state by abutment at the transition between support area 7' and 7 "and the angled portion 8 'and 8" the holding elements 6' and press 6 "radially outward.
  • FIG. 4 shows a plan view in which the preassembled fastener 3 is shown. A repeated explanation of the individual elements is omitted. The illustration is to illustrate the course of the chamfer 12 or 12 '. This begins at the ends seen in the circumferential direction of the fixedly mounted retaining element. 6
  • FIG. 5 shows the preassembled fastener 3 in a perspective view. It can be seen that the ends of the second holding element 6 'and the third holding element 6 "seen in the circumferential direction are set up in the direction of the free end of the threaded pin 4. In this way, the preassembled fastening element 3 can be inserted into the cutout 10. After the fastener 3 is inserted, then in the FIG. 5 upwardly bent ends of the holding elements 6 'and 6 "bent down and thus the respective angled region 8' and 8" is pressed into the gap formed between the base plate 5 and the cutout 10.
  • the holding members 6 'and 6 "are pushed down the more the angled portions 8' and 8", respectively, push outwardly as they abut the end of the chamfer 12,12 'and the outer periphery of the base plate, respectively 5 arrive in the area not reduced in radius.
  • the holding elements 6' and 6" are connected only via the webs 9 with the fixedly attached to the base plate 5 holding member 6 , The webs 9, 9 'must be plastically deformable.
  • the forming after the insertion of the fastener 3 can be done for example by means of a tool which is guided by the threaded pin 4. It can be provided, for example, a kind of stamp, which bears against the upright ends of the holding elements 6 and 6 'and is then guided in the direction of the base plate 5.
  • FIG. 6 A comparison with the simplified embodiment of a fastener with three individual holding elements 6 'and 6 "is in the FIG. 6 shown in a plan view. It will be appreciated that, in contrast to the preferred embodiment described above, the retaining elements 6, 6 'and 6 "have no connection with each other and are inserted individually into the cutout after inserting the base plate with the threaded pin 4. Then they become bolted to the base plate.
  • FIG. 7 is a section through such an arrangement shown. It can be seen that the holding elements 6, 6 'and 6 "although here also have an angled region, but this on the in the FIG. 7 shown lower side does not necessarily have to correspond to a cone. Due to the individual insertion of the holding elements, it is sufficient if they are displaceable in the radial direction of the base plate 5. The fixation takes place here by the individual screwing of the holding elements. Compared to the preferred embodiment described above, this has the disadvantage that the effort during assembly is considerably more complex and in particular a pre-assembly of the fasteners can not be done.
  • FIG. 8 Finally, a further illustration is shown with a disc which a height offset between the surface of the holding elements 6 and 6 'and the surface of the Composite plate compensates. This was preceded by the figure. This shim has the same function as in relation to the embodiment of FIGS. 1 to 5 has already been explained.
