Definitions

  • the invention relates to a fastening element, in particular for fastening a heat- and sound-insulating plate to a substrate, with a holding part which is preferably designed as a plastic injection-molded part and which consists of a hollow shaft piece which can be driven into the plate by means of a setting tool and one which is transverse to the shaft piece
  • Axle is integrally formed pressure plate, which is formed over a large area with respect to the shaft piece, the holding part being insertable into the plate at least so far by means of a sleeve of the setting tool which can be inserted into the shaft piece that the pressure plate rests approximately on the surface thereof, and with a pin a solid material, in particular made of metal, which can be inserted into the shaft piece and can be driven into the ground by the setting tool by means of a ram which can be moved longitudinally in the sleeve and can be subjected to an impact force.
  • a fastening element of this type is known, for example, from EP 0 189 569 B1 (FIG. 12).
  • Part of the shaft piece is with a relatively large inner diameter executed to be able to insert the sleeve; the rest represents a sleeve which is constructed as an axial guide and holding element of the pin.
  • a firm connection between the subsurface, for example an outer wall of the building, and the plate is achieved by the pin driven into the subsurface, the holding force resulting from the pin which is in contact with the contact surface with pressure.
  • Connections of this type have the disadvantage that it cannot be readily determined whether they are designed with a sufficient holding force. Neither immediately after their manufacture nor later, in particular without disassembling the plate, can the secure hold of the connection be checked without having to put up with a possibly considerable additional economic outlay. Apart from the possibly equally high costs that the repair can require in cases in which a plate detaches from the surface, there is also a very considerable risk of accident in the case of loose connections.
  • the holding part may have to be readjusted several times until the pressure plate assumes the desired position in relation to the plate.
  • the pin will come loose from its usually pre-assembled state on the holding part and that it can be expected from the outset that it will not be possible to drive it properly into the ground.
  • the invention has therefore set itself the task of designing a fastener of the type specified in the introduction and a setting tool for such a fastener so that immediately after making the connection between the plate and the substrate, its proper execution can be checked and a faulty connection is immediately recognizable .
  • the coupling can be overcome in a simple manner by the reaction force on the setting tool caused by the impact force on the impact plunger.
  • the impact force in the setting tool is applied explosively to the impact plunger, so that a return force is inevitable. This fact is exploited by the invention and thus put to a useful use; because if a proper connection has not come about after driving the pin, then the entire fastener is not released from the sleeve when the setting tool is withdrawn. It is particularly advantageous if the coupling can only be overcome by the reaction force if a holding force on the pin driven into the plate does not fall below a predeterminable size.
  • such a solution is particularly easy to implement if the coupling can preferably only be overcome by its destruction.
  • the holding part s.B. consists of a plastic and thus a material of relatively low strength, it can be arranged that the coupling can be destroyed without impairing the function of the fastener itself.
  • the coupling can each consist of a coupling element provided on the inner contour of the shaft piece and on the outer contour of the sleeve, the coupling preferably being able to be produced in the form of a threaded connection, a snap connection or a bayonet lock.
  • the coupling is particularly simple as a snap connection, which can be produced by a pure longitudinal movement of the shaft piece against the hollow plunger; it can be brought about quickly and safely with a simple hand movement.
  • a snap connection can be designed in such a way that in the shaft piece at least one cam protruding beyond its preferably circular cylindrical inner contour is provided with an overflow slope for the preferably circular cylindrical outer contour of the hollow tappet, the overflow slope being directed so that it is effective when the shaft piece is pushed onto the sleeve and that the cam can be brought into a recess in the hollow tappet using the overflow slope and the elasticity of the shaft piece and / or the tolerances between the inner contour of the shaft piece and the outer contour of the hollow tappet, wherein the cam and the recess can preferably be designed in the form of a ring.
  • the actual snap action can be brought about by the fact that the cam and the recess are oriented perpendicular to the common longitudinal axis of the shaft piece and the sleeve and their separation has opposing contact surfaces which lie one on top of the other when the cam has entered the recess.
  • the reaction force acts when the pen is hammered into the ground; If it sits firmly in the ground with the intended holding force, the cam will partially destroy or shear off due to the kickback and the setting tool can be released from the fastening element; otherwise the coupling remains and instead the fastening element, completely, is now removed from the connection with the substrate and the plate.
  • the pin is expediently preassembled in the holding part before its shaft piece is coupled to the sleeve of the setting tool.
  • the invention realizes the task according to the invention in a particularly simple manner only by relatively minor changes to the shaft piece and the sleeve.
  • only low costs are required because the required change of the shaft piece is only required on a production tool, for example an injection molding tool, and because the change in the sleeve also only means the correction of a tool; such one-time tool changes are provided at regular intervals anyway.
  • the fastening element and the setting device now form a relatively rigid unit before the connection between the plate and the substructure has been properly established, faulty connections can be avoided, which up to now have arisen when the fastening element does not assume its desired position when setting and must be adjusted.
  • the fastening element can now be captively fastened to the setting tool, a fact which is particularly pleasant during practical operation on a construction site and which helps to reduce the loss rate on fastening elements.
  • a fastening element 1 according to the invention and an associated setting tool 2 are shown in FIG. 1 in aligned common axis 3.
  • a sleeve 21 is provided on the setting tool 2 and can be inserted into the interior of a holding part 11 of the fastening element 1.
  • the circular cylindrical inner contour of the sleeve 21 serves as a guide 21a for an impact ram omitted in the drawing, which can be fired in the direction of impact 31 by the setting tool.
  • Such an arrangement is common in the art.
  • the holding part 11 essentially consists of a shaft piece 11a which extends in the direction of the axis 3 and which ends in a sleeve 11b of a substantially smaller diameter, and a pressure plate 11c which is integrally formed on the shaft piece 11a transversely to the axis 3. It is of relatively large surface area and has an annular shape, the opening provided in it for the insertion of the sleeve 21 into the shaft piece 11a can be closed by means of a captive cover 11d which is integrally formed on the fastening element 1 when the fastening element 1 is properly attached.
  • the holding part 11 is partially cut open in FIGS. 1 and 2, so that a pin 12 can be seen which is inserted into the area of the sleeve 11b adjoining the shaft piece 11a; this is possible to some extent because the pin 12 is usually made with a tip 12a.
  • the pin 12 is provided with a striking surface 12b on which the striker of the setting tool 2 strikes.
  • the sleeve 21 is provided on its inner contour with a recess 41, which is circular here and is a coupling element of a coupling 4 with the fastening element 1.
  • the cross section of the recess 41 essentially follows the cross section of a cam 42, which is designed here as a ring cam and forms the coupling element of the coupling 4 on the shaft piece 11a.
  • an overflow slope 42a is attached and directed so that an end edge 21b of the sleeve 21 can push away the cam 42 when the fastener 1 is pushed pre-assembled over the sleeve 21, and just so far that the cam 42 into the recess 41 occurs and the clutch 4 is made.
  • One contact surface 41b and 42b each on the recess 41 and on the cam 42 which then abut one another and are formed transversely to the axis 3, block the removal of the hollow plunger 21 from the fastening element 1.
  • FIG. 2 shows the individual phases in which a plate 5 is fastened to a substructure 6.
  • the right-hand partial figure a) corresponds to FIG. 1, it is only somewhat smaller than the other partial figures b) to d).
  • An outer contour 21c of the sleeve 21 is adjacent to and guided on an inner contour 11e of the shaft piece 11a after its insertion into the fastening element 1 in accordance with the partial figure b).
  • the fastener 1 is pushed over the sleeve so far that the cam 42 comes into the recess 41 and the clutch 4 is made.
  • the fastening element 1 is thus captively attached to the setting tool 2 and can only be removed again with considerable exertion of force.
  • the fastening element 1 is pushed into the plate 5 until the pressure plate 11c rests on its surface 51 in accordance with sub-figure c).
  • the end face of the sleeve 11b then lies against the base 6, tolerance compensation taking place, for example, as in the drawing, by upsetting the sleeve 11b.
  • the coupling elements 41 and 42 can be dimensioned taking into account the properties of the materials used for this purpose so that a predetermined holding force F stop can be achieved.
