  • the main body is preferably made of durable elastic material such. As elastic plastic or rubber, produced, which is advantageous restoring, that is, on the one hand deformable, on the other hand, would like to take the original shape again.
  • Head, bridge and base are advantageously penetrated by a passage which receives a fastener. So that the passage does not overtake the connector too much weakens, recesses in the base or in the region of the head are advantageously not executed, so that the passage is as completely as possible surrounded by the material of the body.
  • the fastener anchors the connector in the ground or in the substructure.
  • a fastener are best suited elongated metal elements, in particular nails, bolts, rivets or screws. Particularly preferred are in the context of the invention screws, because they can be tightened in stages. In addition, therefore, a screw is assumed as a fastener without this is to exclude other embodiments of the fasteners.
  • the passage is made with a thread to improve the power transmission to the connector.
  • the connector has a force-transmitting cover which is connected to the head.
  • the cover is adapted to the dimensions and the shape of the head, in particular the top of the head and is acted upon by the tightened screw with force.
  • the force-transmitting cover is flat, so plate-like or web-shaped and it can be made of any material that is suitable to transmit the forces acting on the cover by the screw forces on the body, in particular the head of the body.
  • the force-transmitting cover is made of metal, plastic or hard rubber.
  • the force-transmitting cover is preferably penetrated by a passage which is aligned with the passage of the base body, so that the base body and force-transmitting cover can be fixed together by a screw.

  • the receptacle is preferably mounted above a recess which penetrates the head.
  • the cover enhances power transfer from the fastener to the connector. Thanks to the force-transmitting cover, the fastening element transfers the holding force transmitted by the fastening element to the base body in a planar manner, especially on the head. As a result, the fastening element not only fixes the base body to the substrate or a substructure. Rather, when the fastener continues to exert force on the body, a holding force can be exerted on the cladding element to be fastened, not only selectively, but thanks to the force-transmitting cover over the entire cross-sectional area of the head. In this way, the cladding element is secured more secure than before.
  • Decking or other cladding elements can be particularly advantageously fixed by means of the connector described above to the substrate or a substructure, when the side edges of a decking board a groove, hereinafter: edge groove.

  • the side edges of the decking boards attached to the connector are spaced from each other by the width of the bridge.
  • the connector is adapted in each case to the dimension of the cladding elements to be laid.
  • the connector is small in size, for 25 mm thick decking it is larger in size.
  • the web is preferably about 5-10% higher than the lower groove cheek of the decking board, which is to be included in the groove. This embodiment, preferably together with a tapered towards the web and / or the top of the connector head allows a particularly simple insertion of the decking board in the groove of the connector.
  • the laying of the decking boards and the attachment to the connector is advantageously carried out in such a way that a connector is fastened to the substrate or a substructure, is typically screwed. However, the screw passing through the passageway in the connector is not yet fully tightened. If larger decking boards are laid, several connectors are fastened to the ground or substructure. If several rows of decking laid, so are several rows of connectors arranged.
  • a decking board with an edge groove is then placed with the side edge on the top of the base of the base body and the lower groove cheek of the edge groove is pivoted into the groove of the connector between the base and head.
  • the side edge is advantageously deposited on the head of the connector and the head is deflected so far that the lower groove cheek of the edge groove is lowered into the groove of the connector.
  • the decking is now securely held in the connector.
  • the screw in the passage of the connector is further tightened and deforms the connector.
  • the deformation of the connector is not punctiform but flat, by the screw, in particular the underside of the screw head, but also the thread of the screw, acting on the force-transmitting cover, which is inserted in a recess of the head.
  • the screw is tightened until a recess in the head of the connector, which is mounted below the force-transmitting cover, and which passes through the head sectionally as a recess open to the edge, reduced by compressing the head, as close as possible. In this way, holding force is applied to the decking to a greater extent than before, so that the decking board is better secured than in known connectors.
  • the deformability which is a characteristic of elastic connectors, remains unchanged. Since the recess does not extend in the area of the passage, the body is not unduly weakened and the force distribution is uniform.
  • FIGS. 1A and 1B a first embodiment of the connector 10 is shown.
  • the connector 10 comprises a deformable base body 12, a force-transmitting cover 30 and a screw 40.

In the illustrated embodiment, the base is 50mm wide and 35mm long. Centrally on the base 14 extends over the length of the base body 12 of the web 16, which has a width of 6 mm. This is 15 mm wide, so wider than the web 16. Therefore, the base 12 has an undercut 17 in the transition between the head 18 and web 16 on. In the illustrated embodiment, this undercut 17 is slightly chamfered. The undercut 17 forms with the top 19 of the base 14 has a groove 21 with the base 14 and the head 18 of the body as the lower and upper groove cheek.
  • the bottom of the base 14 has compensation recesses 20. These recesses 20 serve as compensation element in the case of deformation of the base body 12 and ensure that no waterlogging forms under the base body 12.
  • the head 18 has a recess 22.
  • This recess 22 has a diamond-shaped cross section and extends through the entire length of the head 18. The shape of the cross section is selected so that the lower side of the recess 22 extends parallel to the undercut of the head 18.
  • the cover 30 extends over the entire area of the head 18.

  • the Cover 30 is inserted through a slot 24 in the head 18 in the body.
  • the head 18 is therefore a bearing 23, in which the cover 30 is fitted and held in a form-fitting manner by terminal latches 25.
  • the cover 30 is made of corrosion-resistant metal and about 1.5 mm thick, but it can also be made of a dimensionally stable, non-brittle plastic. As a result, the cover 30 is weather-resistant and stable so that a favorable power transmission is possible and the cover 30 is not damaged or deformed.
  • the cover 30 has a passage 32 for the screw 40.
  • the passage 32 is aligned with a passage 34 of the main body. These passages serve to receive the screw 40, which extends through the entire main body 12.
  • the screw 40 has, in addition to the screw head 42, an external thread 46, via which the screw 40 can be screwed to a, not shown, substructure.

  • Wooden decking boards 50 are prepared in this embodiment, connected to each other via a connector 10 on a substrate 60 as a terrace floor 70 become.
  • the decking board 50 has an edge groove 52 on each of its longitudinal sides. By means of this edge groove 52, the decking boards 50 have been loosely inserted into the fastened to the substrate 60 connector 10 by pivoting or latching. The latching is done by moving the head when loading or laying the decking board 50. After inserting the decking board 50, the screw can be inserted into the connector 10 and tightened. As a result, the screw head 42 (vg. Fig. 1 ) exerts a pressing force on the cover 30.
  • This pressure is passed through the cover 30 on the base body 12 of the connector 10.
  • the elastic base body 12 deforms under this pressure, in particular in the region of its head 18.
  • the head 18 is pressed in the direction of the lower groove edge 54 of the edge groove 52 and thus the decking board 50 is fixed by the connector 10.
  • the decking board 50 rests against the base 14 of the connector 10 on its upper side 19. As a result, a gap 56 is formed between the substrate 60 and the decking board 50. Over this gap 56 waterlogging can be avoided.
  • the top 19 of the connector is flat. It is wider than the edge groove 52 so that the decking board 50 rests securely on the base 14.
  • the laying of the decking can be done by first the connector is fixed to the ground with the screw, but the screw is not yet completely screwed or tightened. Then the decking boards are inserted into the connector and now the screw is fully tightened through the gap between the decking boards. In this way, the connectors are already fixed before swinging the decking and the final, complete tightening of the screw can be done in coordination with the already inserted decking.
