AnwendungsgebietArea of application

Das Anwendungsgebiet der vorliegenden Erfindung ist das Bauwesen zum Verbinden von Bauelementen, von denen mindestens ein Bauelement aus Holz besteht. Bei der Montage von Bauelementen wie Platten, Balken, Pfosten und dergleichen stellt sich die Frage nach der Größe des Verbindungsmittels, insbesondere seiner seitlichen Ausdehnung, um Kräfte über eine größere Fläche zu übertragen. Überschreitet die Größe des Verbindungsmittels eine bestimmte Breite, ist dies nicht mehr ohne weiteres durch Extrusion realisierbar, was zu Produktionsproblemen und erhöhten Kosten führt.The field of application of the present invention is construction for connecting building elements, at least one of which is made of wood. When assembling building elements such as panels, beams, posts, and the like, the question arises regarding the size of the connecting element, particularly its lateral extension, in order to transmit forces over a larger area. If the size of the connecting element exceeds a certain width, this can no longer be easily achieved by extrusion, which leads to production problems and increased costs.

Further purposes, features, advantages and possible applications will become apparent from the following description of some embodiments and the associated drawings.
  • The Figures 1a, 1b and 1c show a front and rear view of the connecting device,
  • The Figures 2a, 2b and 2c show an exploded view of the Figures 1a, 1b and 1c ,

  • Figure 4 shows a side view of the screw connection device, and
  • Figure 5 shows a side view of the screw connection device connecting two components. A device according to the invention is shown in Figure 1b designated by the reference number 100.
  • Figure 5 shows a connecting device 100 according to the invention in the assembled state. The connecting system according to the invention is realized by attaching a first connecting element consisting of a first part 101 and a second part 102. The first part 101 has a series of screw seats/holes 104 and advantageously a first part of a link 105a. The second part 102 also has a series of screw seats 104 and advantageously a second part of a connection 105b. The first part of the first element 101 has an end 106 housed in the seat 117 of the first part of the second element 111. The second part of the first element 102 has a seat 107 that receives an end 116 of the second part 112 of the second element.

Zwischen dem ersten Teil des ersten Elements 101 und dem zweiten Teil des ersten Elements kann auch nur eine Kontaktfläche vorgesehen sein, die einen Anschlag zwischen den beiden Teilen 101 und 102 bildet.Between the first part of the first element 101 and the second part of the first element, only one contact surface can be provided, which forms a stop between the two parts 101 and 102.

Jedes Teil 101 und 102 des ersten Elements weist eine Reihe von Schlitzen/Löchern 104 für Befestigungselemente auf, die vorzugsweise in Richtung des ersten Teils des ersten Elements 101 geneigt sind. In diese Löcher werden Schrauben 201 zur Befestigung des ersten Elements an einem Bauelement 200 eingesetzt. Zur Erleichterung der Befestigung können Löcher 103 zur Positionierung des Elements mit Hilfe von Schrauben vorgesehen werden.Each part 101 and 102 of the first element has a series of slots/holes 104 for fastening elements, which are preferably inclined towards the first part of the first element 101. Screws 201 are inserted into these holes for fastening of the first element is inserted into a component 200. To facilitate fastening, holes 103 can be provided for positioning the element using screws.

Die Anzahl der Schrauben 201 des zweiten Teils des Elements 102 und damit auch die Anzahl der Schräglöcher 104 ist größer als die Anzahl der Schräglöcher des ersten Teils des Elements 101. Somit sind die Kräfte, die von den Schrauben am zweiten Teil des Elements 102 auf das Element übertragen werden, größer als die Kräfte, die von den Schrauben 201 am ersten Teil des Elements 101 übertragen werden. Dadurch wird eine Kraft erzeugt, und diese Kraft auf die Verbindung wird durch die Neigung und die Anzahl der Schrauben 201 erhöht. Die Verbindung zwischen den beiden Elementen steht nicht unter Spannung, so dass es sich auch um eine einfache Kopf-an-Kopf-Verbindung handeln kann, so dass die Verbindung auch nur durch zwei sich berührende Flächen gebildet werden kann.The number of screws 201 of the second part of element 102, and thus also the number of inclined holes 104, is greater than the number of inclined holes in the first part of element 101. Thus, the forces transmitted by the screws on the second part of element 102 to the element are greater than the forces transmitted by the screws 201 on the first part of element 101. This creates a force, and this force on the connection is increased by the inclination and the number of screws 201. The connection between the two elements is not under tension, so it can also be a simple head-to-head connection, meaning the connection can also be formed by just two touching surfaces.

Jedes Teil 101 und 102 des ersten Elements weist eine Reihe von Schlitzen/Löchern 104 für Befestigungselemente auf, die vorzugsweise in Richtung des ersten Teils des ersten Elements 101 geneigt sind. In diese Löcher werden Schrauben 201 zur Befestigung des ersten Elements an einem Bauelement 200 eingesetzt.

Screws 201 are inserted into these holes for fastening the first element to a building element 200. To facilitate fastening, holes 103 for Positioning of the element using screws is provided.

Die Anzahl der Schrauben 201 des zweiten Teils des Elements 102 und damit auch die Anzahl der Schräglöcher 104 ist größer als die Anzahl der Schräglöcher des ersten Teils des Elements 101. Somit sind die Kräfte, die von den Schrauben am zweiten Teil des Elements 102 auf das Element übertragen werden, größer als die Kräfte, die von den Schrauben 201 am ersten Teil des Elements 101 übertragen werden. Dadurch wird eine Kraft erzeugt, und diese Kraft auf die Verbindung wird durch die Neigung und die Anzahl der Schrauben 201 erhöht. Die Verbindung zwischen den beiden Elementen steht nicht unter Spannung, so dass es sich auch um eine einfache Kopf-an-Kopf-Verbindung handeln kann, so dass die Verbindung auch nur durch zwei sich berührende Flächen gebildet werden kann.The number of screws 201 of the second part of element 102, and thus also the number of inclined holes 104, is greater than the number of inclined holes in the first part of element 101. Thus, the forces transmitted by the screws on the second part of element 102 to the element are greater than the forces transmitted by the screws 201 on the first part of element 101. This creates a force, and this force on the connection is increased by the inclination and the number of screws 201. The connection between the two elements is not under tension, so it can also be a simple head-to-head connection, meaning the connection can also be formed by just two touching surfaces.

Jedes der Teile 111 und 112 des zweiten Elements weist eine Reihe von Schlitzen/Löchern 104 für Befestigungselemente auf, die vorzugsweise in Richtung des zweiten Teils des zweiten Elements 112 geneigt sind.

Zur Erleichterung der Befestigung können Löcher 103 zur Positionierung des Elements mit Hilfe von Schrauben 202 am Bauelement vorgesehen werden.Each of the parts 111 and 112 of the second element has a series of slots/holes 104 for fastening elements, which are preferably inclined towards the second part of the second element 112. Screws 201 are inserted into these holes for fastening the first element to a building element 200. To facilitate fastening, holes 103 for positioning the element with the aid of Screws 202 are provided on the component.

Die Anzahl der Schrauben 201 des ersten Teils des zweiten Elements 111 und damit auch die Anzahl der Schräglöcher 104 ist größer als die Anzahl der Schräglöcher des zweiten Teils des zweiten Elements 112, die geringer ist. Somit sind die Kräfte, die von den Schrauben 201 am ersten Teil des zweiten Elements 111 auf das Element übertragen werden, größer als die Kräfte, die von den Schrauben 201 am zweiten Teil des zweiten Elements 112 übertragen werden. Dadurch entsteht eine und diese Kraft auf die Verbindung wird durch die Anzahl und/oder die Neigung der Schrauben 201 erhöht.The number of screws 201 of the first part of the second element 111, and thus also the number of angled holes 104, is greater than the number of angled holes of the second part of the second element 112, which is smaller. Thus, the forces transmitted to the element by the screws 201 on the first part of the second element 111 are greater than the forces transmitted by the screws 201 on the second part of the second element 112. This creates a force on the connection, and this force is increased by the number and/or inclination of the screws 201.

Zur Erleichterung des Zusammenbaus der erfindungsgemäßen Vorrichtung 100 können die beiden Elemente beispielsweise mittels Verbindungen 105, 115 vormontiert werden, die durch ein vorstehendes Element 105a, 115a und einen gemütlichen Sitz 105b, 115b gebildet werden, und zur Fixierung der Teile in ihrer Position wird für jedes Element mindestens ein Stift 108 eingesetzt, der die Verbindung verriegelt und den Zusammenbau erleichtert. In einer nicht dargestellten Variante kann die Anzahl der Teile des ersten Elements und/oder des zweiten Elements mehr als zwei betragen, beispielsweise drei, wobei mindestens ein Teil eine größere Anzahl von Schrauben 201 und/oder Schraubensitzen 104 aufweist als die anderen Teile des Elements.To facilitate assembly of the device 100 according to the invention, the two elements can be pre-assembled, for example, by means of connections 105, 115 formed by a protruding element 105a, 115a and a comfortable seat 105b, 115b. To fix the parts in position, at least one pin 108 is inserted for each element, locking the connection and facilitating assembly. In a variant not shown, the number of parts of the first element and/or the second element can be more than two, for example three, with at least one part having a greater number of screws 201 and/or screw seats 104 than the other parts of the element.
