Definitions

  • the invention relates to a connecting device for connecting floorboards or panels to beams.
  • Floor areas for example terrace floors, are formed by floorboards or panels that are supported by a substructure.
  • the substructure comprises girders which are aligned parallel in a girder longitudinal direction and are arranged at even girder spacings.
  • the planks or panels are placed on the girders in such a way that they can transmit bearing forces to at least two girders.
  • Planks or panels can be made at least partially from wood, from composite wood, from a wood-plastic mixture (WPC: Wood-Polymer-Composite), from plastic, from metal, from stone or from ceramic.
  • WPC Wood-Polymer-Composite
  • Common decking boards have a thickness in the range from 15 to 30 mm, a width in the range from 9 to 16 cm and a length in the range from 1 to 3 m. With panels, the difference between length and width is smaller and often square panels are also used.
  • the substructure is designed in such a way that the boards or panels are not exposed to waterlogging.
  • Various solutions are known for connecting floorboards to beams. With simple solutions, the boards are attached to the beams with nails or screws. Other connections include fasteners that engage longitudinal grooves in the planks and are screwed to the beams. In the case of simple solutions, individual boards can only be removed with great effort after the floor has been installed.
  • the connecting elements are screwed to supports and connected to a board via a detachable snap-in connection, which makes it easier to detach and reinsert boards.
  • EP 2 878 743 B1 describes solutions with boards with locking receptacles, preferably in the form of two longitudinal grooves, in which locking heads engage.
  • the latching heads are formed in pairs on connecting elements.
  • the distance between the two locking heads of the connecting elements must match the distance between the locking receptacles or longitudinal grooves of the boards.
  • Either all usable boards must have a standard spacing between the latching receptacles or longitudinal grooves, or connecting elements with different spacings between the latching heads must be provided.
  • Holding areas of the connecting elements are held in grooves in the profile rails in such a way that the connecting elements with the locking heads can only be displaced in the longitudinal direction of the groove, but cannot be separated from the profile rail transversely to the longitudinal direction.
  • the profile rails are arranged parallel to each other as carriers.
  • the connecting elements must be inserted and positioned into the grooves of the profile rails from one end face of the profile rail. If the end faces of the profile rails are difficult to access, the insertion of the connecting elements can be very complex.
  • connecting elements must be inserted into the grooves before the profile rails are arranged.
  • connecting elements can fall out of the groove on one end face. If the installed profile rails do not have the correct number of connection elements after assembly, the profile rails must be removed again, provided with the correct number of connection elements and reassembled.
  • the connecting elements with the locking heads in this plurality of profile rails must each be correctly positioned so that all the locking heads of the connecting elements in these profile rails are each precisely assigned to a locking receptacle or longitudinal groove of the board to be used. If a locking head is damaged when removing a board so that the connecting element with the damaged locking head has to be replaced, then all boards must be removed and the profile rail with the defective connecting element dismantled so that the connecting elements up to the defective connecting element at one end of the profile rail must be removed can be taken. If the profile rails of the carrier are still connected to connecting profiles running transversely to the longitudinal direction of the carrier, then the connecting profiles connected to them must also be released in order to remove a profile rail.
  • the connecting elements must have a guide area that fits positively into a groove in the profile rails and two specific locking heads at a predetermined distance. Wooden floorboards show strong expansion changes across their length, depending on the moisture. Therefore, connecting elements that can be used with wooden planks must have variable-length areas between the locking heads, these variable-length areas being able to provide an unsuitable spacing between the locking heads during assembly, which is associated with locking problems.
  • the object according to the invention is to find a solution in which, if possible, all of the planks and panels that can be used for floor coverings can be connected to supports with little effort and using as few individual parts as possible.
  • connecting elements which extend in the form of a strip in an element longitudinal direction, comprise a first and a second main surface as outer surfaces, two side surfaces connecting the main surfaces and two end surfaces connecting the main surfaces and the side surfaces and in the second main surface have at least two grooves extending transversely to the longitudinal direction of the element, which considerably facilitate the construction of a floor with planks or panels and the removal and reinsertion of planks or panels compared to the solutions according to the prior art.
  • At least one plank or panel is attached to the first major surface of a connecting element. Thereafter, the connecting element with the at least a plank or board can be arranged at the desired location on at least two carriers so that each carrier in the area of the connecting element comes into frictional and / or form-fitting connection with an area adapted to the grooves of the connecting element.
  • the band-shaped connecting elements preferably comprise plastic, optionally wood-plastic material, or metal.
  • the connecting elements, at least in the grooves comprise areas with elastic material made of plastic or rubber.
  • the connecting device comprises connecting elements which can each be connected to at least one plank or plate and to at least two carriers. This eliminates the need to precisely position at least two elements for individual connections between a board or panel and at least two beams.
  • each band-shaped connecting element extends transversely to the longitudinal direction of the carrier over at least two carriers, with at least two grooves of each connecting element each receiving an area of the at least two carriers and a frictional and / or form-fitting retaining connection between the connecting element and achieve the at least two carriers.
  • the planks or panels arranged on the at least one connecting element can be removed from their position as part of the floor.
  • only the grooves of the at least one connecting element connected to the board or board need to be placed on the at least two carriers to achieve the holding connection.
  • planks or panels can be connected to beams using fewer individual parts. For example, if the connecting element is 1.8 m long and rests on six girders at regular intervals of 30 cm, six connections between the board and girders are achieved with this band-shaped connecting element, which requires the use of six connecting elements in the solutions from the prior art would. Because in the connection element according to the invention the first main surface is ready for connection to at least one plank or panel, essentially all planks and panels that can be used for floor coverings can be attached to the first main surface and connected to carriers via the strip-shaped connection element. For the connection between the first main surface and a plank or plate, the planks or plates, in addition to a contact surface, do not have to have any specific shaped elements, such as, for example, longitudinal grooves.
  • the connection between the band-shaped connecting element and the plank or board can be firmly established, for example by means of screws or an adhesive connection.
  • This fixed connection increases the load stability of the two-layer combination of plank or board and connecting element. This also applies if two or more planks or panels are attached to a connecting element.
  • the load stability is primarily determined by the tensile strength of the connecting element, with a high tensile strength being able to be provided with a thin connecting element.
  • connection element After the at least one plank or plate has been fastened to the connecting element, its orientation relative to the carriers is determined on the basis of the grooves in the connecting element. This is true because the grooves accommodate areas of girders so that the grooves run parallel to the longitudinal direction of the girders. The longitudinal direction of the connecting element and the main direction of the plank or panel are aligned parallel and run transversely to the longitudinal direction of the support. With the connection element according to the invention, the assembly and alignment problems that occur with various connection elements attached to the board can be prevented.
  • the connection of grooves of the connecting element with girders enables the connecting element and thus the board or board attached to it to be moved in the longitudinal direction of the girder. This ensures a desired positioning or position correction with little effort.
  • the connecting element in an advantageous embodiment has at least one stop element, but preferably at least two stop elements, each stop element protruding over the first main surface and the Positioning of a lateral edge allows at least one plank or plate to be connected to the connecting element.
  • stop elements can be designed, for example, as stop knobs or stop webs protruding from the first main surface.
  • stop knobs or stop bars can also define the distance between planks or panels running parallel to one another.
  • the stop knobs or stop webs form both a stop for the board or board connected to their connecting element and for the board or board of the adjoining connecting element. Between two boards or panels that are adjacent transversely to the longitudinal axis of the connecting element, a distance is created which corresponds to the corresponding extension of the stop knobs or stop webs.
  • stop knobs or stop webs are not formed on the edge of the connecting element, there is between the stop knobs or stop webs and the lateral edge of the connecting element a partial area of the first main surface on the one edge area of the plank or board of the neighboring one Connection element rests.
  • the width of the connecting elements according to the invention is adapted to the width of the common boards or panels.
  • the width of the connecting elements and thus their extension between the two side surfaces is in the range of 8-16 cm.
  • the connecting elements can also be narrower than the boards or panels connected to them. This is why a connecting element with the width of the narrowest common boards can be used for all boards and panels.
  • each plank or plate is connected to a connecting element and rests both on this and on an adjacent connecting element.
  • each plank or panel rests with a lateral edge area on the two connecting elements that are adjacent in the direction transverse to their longitudinal axes. Between the adjacent connecting elements there are central areas of the planks or panels without any underlying connecting elements. If the floor is to be laid out with wide plates, two adjacent connecting elements can be connected to each plate in a row, with one connecting element preferably protruding laterally over the plates and the other being set back a little laterally under the plates, so that the free edge of the plate can be placed on another adjacent connecting element.
  • the length of the connecting elements i.e. their extension along the longitudinal direction of the element, is preferably in the range of 1 to 3 m.

  • the depth of the grooves in the connecting element is preferably in the range of 7-27 mm.
  • the layer thickness remaining between the groove base and the second main surface is preferably in the range from 3 to 13 mm. In the case of terrace floors, the appropriate height of the structure, i.e. the substructure under the girders, the girders, the connecting element and the boards or panels is in the range of 100 - 170 mm.
  • the deformation of wooden planks can be reduced and / or impact sound insulation can be achieved using elastic material, for example between the groove base and the first main surface of the connecting element.
  • the grooves for achieving the frictional and / or form-fitting connections between the connecting element and the carriers are formed at fixed intervals on the connecting element in such a way that a groove is assigned to each carrier in the region of the connecting element.
  • a connecting element comprises grooves at equal intervals over its entire length, this connecting element can be used for carrier arrangements in which the distance between adjacent carriers corresponds to the groove spacing or a whole multiple of the groove spacing.
  • the distance between central areas of adjacent grooves is, for example, 10 cm, optionally 20 cm, in particular 30 cm.
  • Such connecting elements can be used for distances between the beams of 20 cm, 30 cm, 40 cm, 50 cm or 60 cm or 20 cm, 40 cm, 60 cm, or 30 cm, 60 cm.
  • each connecting element achieves a connection of at least one plank or panel to at least two beams.
  • Advantageous connecting elements have at least 5 grooves, but preferably at least 10 grooves, and can achieve connections to at least 5 or at least 10 carriers.
  • connecting elements can be placed on the carrier to be mounted, for example at both ends, before the carrier is fastened to an underlying structure.
  • This use of the connecting elements as assembly jig ensures that the carriers are available with the desired spacing and can be attached to a substructure in this desired arrangement.
  • the grooves of the connecting elements are adapted to a rectangular carrier cross-section. This is sufficient, for example, when the holding forces to be overcome to remove a connecting element with at least one plank or plate from the girders can be small, for example when the weight of the planks or plates ensures a sufficient contact connection to the girders.
  • the connecting device comprises profile rails, for example made of metal or plastic, which are arranged on a substructure as a carrier or on a carrier can be placed on and connected to these, for example with a screw connection.

  • the planks or boards and the beams can essentially be chosen freely.
  • the planks or panels only need to have a connecting surface that can be firmly connected to the first main surface of the connecting element.
  • the carriers only need to be connectable to the profile rail.
  • the height of the profile web between the main profile area and the free end of the profile web is at most as great as the depth of the grooves, but preferably somewhat smaller, so that the bearing forces of the boards or panels do not come from the free end of the profile webs be included.
  • the bearing forces of the planks or panels are transferred from the connecting elements to the main profile area via partial areas on both sides of the grooves.
  • Elastic material for achieving impact sound insulation is therefore preferably arranged on the connecting elements at least in contact areas with the main profile areas, that is to say on both sides of the grooves in the second main area.
  • An advantageous profile rail comprises a rectangular receiving area open in cross section on a first profile side, which is preferably adapted to a common cross section of carriers, the profile rail in the receiving area resting on the carrier with a contact surface opposite the opening of the receiving area.

  • Fig. 10 shows a further embodiment of a connecting element 3 with a first and a second main surface 3 a, 3 b, which are offset in partial areas towards the interior of the connecting element 3.
  • the connecting element 3 shown comprises an inner connecting surface from which ribs protrude on one side against a plank 1 and on the other side against the carrier 2.
  • the first and the second main surface 3a, 3b are both formed by the end faces of the ribs and by the U-shaped regions between adjacent ribs.
  • the end faces of ribs of the first main face 3a are arranged at the outer planar delimiting face of the connecting element 3 and bear against it at least one board 1.
  • the boards 1 cover bores 6 which lead through the inner connecting surface.
  • the ribs of the second main surface 3b face the girders 2 and include groove sections of the grooves 5.
  • the contact areas between a connecting element and girders 2 are reduced to areas of the ribs.
  • the connecting element 3 with at least one plank or plate can be arranged on carriers in such a way that each carrier in the region of the connecting element comes into frictional and / or form-fitting connection with an area adapted to the grooves of the connecting element.
  • Connecting elements 3 with inwardly offset partial surfaces comprise less material and can nevertheless ensure a high degree of dimensional stability. Another advantage of the connecting elements with inwardly offset partial surfaces is that between the boards 1 and the connecting elements 3 connected to them there are ventilated areas which avoid waterlogging on the underside of the boards. In addition, these connecting elements can be designed in such a way that they have a smaller thickness in the areas of attachment to the boards, which makes it easier to insert connecting screws.
