Description

The invention relates to a ridge system for attaching and / or connecting workpieces, in particular the connection of wooden planks for the production of solid wood panels and the connection of solid wood panels with each other

Such multi-part lattice systems with one or two-sided dovetail formation are particularly suitable for the production and installation of wall, ceiling and floor elements for timber constructions, preferably using renewable raw materials.

According to the current state of the art for the production of solid wood panels, the ridge strips are inserted in their entire length from the beginning or end of the dovetail groove, such as in the EP 1 734 200 A1 shown.

An absolutely firm connection is therefore no longer possible, so that in the patent the use of glue on the side edges of the dovetail grooves is mentioned. However, this contradicts the desire to avoid chemical products and also prevents the natural swelling and shrinkage of solid wood, causing the panels to warp.

According to the EP 2 823 114 A1 are milled for coupling and connecting solid wood panels with each other both in the same and in the angled plane at the longitudinal edges of the cross-layers to be connected parallel dovetail grooves. In these grooves then two mutually wedge-shaped ridge strips are used.

• – Die Koppelungsleisten werden gemäß der EP 2 823 114 A1 fest verspannt, mit der Folge, dass beim Brettsperrholz die außenstehenden Lagen nach außen gespreizt werden. Die inneren Lagen, die für eine sichere Verleimung wichtig sind, werden mit der durchgehenden Ausfräsung an der Kante des Holzpaneels eingekürzt und sind dadurch für eine Verbindung verloren.
• – Die Koppelungsleisten können aufgrund ihrer Länge nur in Längsrichtung der Holzfaser hergestellt werden. Die Kräfte der zu verbindenden Holz-paneele wirken sich daher quer zur Faserrichtung der Koppelungsleisten aus, welche dadurch an ihrer dünnsten Stelle brechen können (Haupt-krafteinwirkung).
• – Wegen der Länge der Koppelungsleisten, die in Richtung der Längskante eines Holzpaneels eingebracht werden, ist eine spätere Demontage eines Holzpaneels innerhalb einer Gesamtkonstruktion nicht mehr möglich, da angebaute Konstruktionen dies verhindern.

This type of coupling bar has the following disadvantages:

• - The coupling strips are according to the EP 2 823 114 A1 tightly clamped, with the result that in the cross laminated timber, the outer layers are spread outwards. The inner layers, which are important for a secure gluing, are shortened with the continuous cut-out on the edge of the wooden panel and are thereby lost for a connection.
• - The coupling strips can be produced only in the longitudinal direction of the wood fiber due to their length. The forces of the wood panels to be joined therefore have a transverse effect on the fiber direction of the coupling strips, which can thereby break at their thinnest point (main force).
• - Due to the length of the coupling strips, which are introduced in the direction of the longitudinal edge of a wooden panel, a subsequent dismantling of a wooden panel within an overall construction is no longer possible because attached constructions prevent this.

In the current state of the art, ridge strips are introduced in their entire length from the beginning or end of the dovetail groove. The disadvantage of this technique is that the ridge strips are made longitudinally to the wood fiber and thus the optimum durability of the material wood is not achieved. In addition, disassembly of a single wall within a building is not possible without sawing or milling out the parts.

By virtue of the invention, the above-cited disadvantages of the current state of the art can be avoided in a simple and cost-effective manner.

According to the invention, the lattice system comprises a workpiece having a dovetail groove extending in the groove longitudinal direction, and two formed as a ridge strips, outer parts which extend in Nutlängsrichtung and facing each other, wherein the opposite outer edges of the outer parts in the opposite groove flanks engage the dovetail groove, wherein the mutually facing inner edges of the outer parts are at least partially inclined to the Nutlängsrichtung, and wherein the outer parts in Nutlängsrichtung have a dimension of a maximum of 50 cm, in particular a maximum of 30 cm.

The dimension of the outer parts in Nutlängsrichtung is limited to about the size of the width of the workpiece or another workpiece. In particular, at least one of the workpieces to be joined is a wood plank, wherein the dimension of the outer parts in the groove longitudinal direction is preferably limited to the width of the wood plank. As a result, each wood plank can be fixed individually in a desired position with a dovetail groove milled transversely to the plank longitudinal direction.

The division of the ridge strip into several parts makes it possible to shape these wedge-shaped with each other in order to achieve an absolutely firm connection. The multipiece rail can be used anywhere on the dovetail groove and does not have to be inserted from the end of the same.

Multi-ply solid wood panels for walls, ceilings or floors can be produced with the multipiece ridge strip. Even the firm connection of wood panels with each other is possible.

Preferably, a mandrel protruding in the direction of the adjacent groove flank of the dovetail groove is provided on the mutually remote outer flanks of the outer parts for fixing the outer parts in the groove longitudinal direction.

The dovetail groove can be designed according to one embodiment as a bag-shaped milled recess and form a depth stop for the outer parts in the groove longitudinal direction.

According to a further embodiment of the ridge strip system, the outer parts form a form-locking connection, which couples the outer parts substantially groove-free in the groove longitudinal direction and allows a relative displacement of the outer parts transversely to the groove longitudinal direction.

Preferably, a center wedge is provided which extends in the groove longitudinal direction between the outer parts, wherein the mutually facing inner edges of the outer parts form a wedge-shaped gap for receiving the central wedge.

Here, the mutually facing inner edges of the outer parts may have a groove extending in the groove longitudinal direction of the dovetail groove for receiving the central wedge.

Alternatively, it is conceivable that the mutually facing inner edges of the outer parts are designed as inclined to the groove longitudinal direction, flat surface.

Particularly preferably, the two outer parts are formed identically in order to minimize the production cost.

According to another embodiment of the ridged system, the outer parts are made of solid wood, with the wood fibers of the outer parts standing upright in the dovetail groove. The central wedge is preferably also formed of solid wood, wherein the wood fiber of the central wedge preferably extends in the longitudinal direction of the dovetail groove. Wood fibers have a particularly high tensile strength in the fiber direction, so that a particularly strong and resilient connection is formed transversely to the dovetail groove between the two workpieces to be joined. A design of the two outer parts made of solid wood with standing upright in the dovetail groove fiber direction is possible due to the dimension of the outer parts in Nutlängsrichtung of less than 50 cm, in particular less than 30 cm.

According to an alternative embodiment, the outer parts are injection-molded parts, wherein the injection-molded parts are produced in particular from renewable raw materials. Such injection-molded parts are characterized by a simple shaping and good, homogeneous strength values, in particular also a sufficient tensile strength.

Further, another workpiece may be provided with a further dovetail groove which is parallel to and directly adjacent to the dovetail groove of the workpiece, the outer portions each protruding from the dovetail groove beyond the workpiece and engaging the further dovetail groove of the further workpiece.

The invention also comprises a multi-layer solid wood panel for walls, ceilings or floors, comprising such a rafter system, wherein the workpiece is a wood plank whose dovetail groove extends in the longitudinal direction of the wood plank and wherein the further workpiece is also a wood plank whose dovetail groove is transverse to the longitudinal direction of the wood plank Wooden plank runs.

According to a preferred embodiment of the multilayer solid wood panel corresponds to a dimension of the two outer parts of the lattice system in the groove longitudinal direction a maximum width of the wood plank whose dovetail groove extends transversely to the longitudinal direction of the wood plank.

Finally, the invention also includes a multi-ply solid wood panel for walls, ceilings or floors, with such a ridge system, wherein the workpiece is a Kantel whose Schwalbenschwanznut extending in the longitudinal direction of the shroud, and wherein the further workpiece is a wood plank, the dovetail groove transversely to the longitudinal direction Wooden plank runs.

In this case, a plurality of parallel arranged cantilevers are preferably provided which form a central position of the solid wood panel, being arranged on opposite sides of the boards wooden planks, each forming an outer layer, and wherein the edges are spaced apart, so that a cavity for receiving sound insulation material is formed.

The 1 shows a formed as a wood plank workpiece 17 with a dovetail groove 14 extending in a groove longitudinal direction 18 extends, as well as the splitting one on the outer edges 12 parallel ridge bar. By inserting the wedge-shaped middle part 15 be the two outer parts 11 the ridge system on the flanks of the dovetail groove 14 pressed and thus made an absolutely solid connection. So that the two outer parts of the ridge system are not moved in the longitudinal direction during the Anpressvorgangs, can Fixierdorne 16 be used on the outer edges. These are made by inserting the middle wedge 15 pressed into the flanks of the two opposite dovetail grooves. The 12 shows the use of the lattice system to build a three-ply wall. The planks in the middle layer are provided on both sides with a Schwalbenschwanznute in the longitudinal direction of the screed. The subsequent planks have in the direction of the central position dovetail grooves transverse to the screed. In the direction of the outer layers, the dovetail grooves are directed along the screed. The planks of the two outer layers have on the inside again dovetail grooves transverse to the screed. The fixation of the planks in each case in the middle of their width shifts the effects of natural swelling or shrinkage in the comb gaps between the individual planks. This avoids distortions in the overall construction. The position of the planks in the middle position is determined by the distance of the milling in the outer planks. The position of the planks in the outer layers is fixed by the use of a suitable mandrel in the predetermined position. The ridge system is preferably limited to the width of a screed with cross-milled dovetail groove. This allows each screed mounted in a simple manner and fixed exactly in the predetermined position.

The two-sided ridge system has three parts, the two formed as ridge strips, outer parts 11 on the inner flanks 13 run in a wedge shape, on the outer edges 12 however, they are aligned parallel to each other so that they fit into a matching dovetail groove 14 by inserting the wedge 15 form a solid construction. The strength of the ridge rail is increased by the fact that the wood fibers stand upright in the dovetail groove. In other words, this means that the wood fibers of the outer parts 11 in the Essentially perpendicular to a groove bottom 19 the dovetail groove extend. Since wood is particularly tear-resistant in the direction of the grain, the force for joining the workpieces thereby increases by a multiple. In the 1 . 2 . 3 and 11 the frontal wood surfaces are hatched. It also becomes clear that the wood fibers of the middle wedge 15 extend substantially in the longitudinal direction of the dovetail groove, so that the middle wedge 15 without appreciable deformation in Nutlängsrichtung between the two outer parts 11 let go.

Furthermore, a suitable mandrel is 16 on the two outer parts (ridge strips) 11 provided, the slipping in the longitudinal direction of the dovetail groove 14 prevented. According to 1 Such a fixing mandrel is made for example of hardwood and in one on the outer edge 12 of the outer part 11 provided blind bore pressed.

The outer parts 11 of the lattice system have in Nutlängsrichtung a dimension x of a maximum of 50 cm, in particular a maximum of 30 cm, so that a production of solid wood with standing upright in the dovetail groove wood fibers is easily possible. Particularly preferably, the dimension x corresponds to the outer parts 11 a maximum width b of the executed as a wood plank workpiece. As already mentioned above, this makes it possible to attach each screed in a simple manner and fix it exactly in the predetermined position (see 12 to 15 ).

In the embodiment according to the 2 and 3 show the two outer parts 21 of the ridge system on the inner flanks 31 an expiring groove 32 on, with the exterior parts 21 on the outer flanks 22 however, they are aligned parallel to each other so that they fit into a matching dovetail groove 23 by inserting the wedge 24 form a solid construction. The strength of the ridge rail is increased by the fact that the wood fibers stand upright in the dovetail groove. Since wood is particularly tear-resistant in the direction of the grain, the force for joining the workpieces thereby increases by a multiple. In a so-called leaking groove 32 the groove depth decreases in the longitudinal direction of the groove 32 (please refer 3 ).

The 4 shows a three-part rail system, in which the outer parts 44 and the middle wedge 44 be produced by injection molding. The components for the injection molding compound are wood fibers and optionally sugarcane reinforcements or binders. Due to the production at high temperature, the end products are extremely pressure-resistant and in this capacity are comparable to hardwood. In addition, they are not attacked by wood pests.

The two exterior parts 41 of the ridge system point on the inner edges 51 an expiring groove 52 on (see 5 ), with the exterior parts 41 on the outer flanks 42 however, they are aligned parallel to each other so that they fit in a suitable dovetail groove 43 by inserting the wedge 44 form a solid construction. Slippage in the longitudinal direction of the swallow-tail groove 43 is through a suitable thorn 45 on the two outer edges 42 prevented. The thorn 45 is preferably in one piece to the outer parts 41 formed. In addition, a gearing closes 46 the two outer parts 41 slippage among each other. The two exterior parts 41 are identical and will be like the wedge 44 produced by injection molding, preferably from renewable raw materials (bioplastic).

The 6 shows a manufactured by injection molding ridge system of two identical parts, wherein a part is rotated by 180 degrees, so that both parts form a unit and fit into a dovetail groove. The inner flanks of the two halves are wedge-shaped aligned with each other, so that they give a tight connection within the Schwalbenschwanznute by mutual displacement. Both parts have towards the center of a resilient arc with one-sided aligned teeth. This connects both parts with each other. By inserting a metal pin in the groove formed by both parts on the underside of the spring arches are pressed apart or the teeth dissolved, whereby disassembly is possible. Both parts have on the from the Dovetail groove projecting part of a bevelled edge, so that they can fix together a arranged transversely to Schwalbenschwanznute workpiece with dovetail formation in a freely selectable position. The two parts of the ridge system can be secured in position in their final position by means of a pin.

In the embodiment according to the 6 to 8th the trowel system has two identical parts 61 with one part rotated 180 degrees so that both parts form a unit and fit into a dovetail groove. The inner flanks 71 the two halves 61 are aligned wedge-shaped to each other, so that they result in a tight connection within the Schwalbenschwanznute by mutual displacement. Both parts have a springy bow towards the middle 72 with one-sided gearing 73 , This connects both parts with each other. By inserting a metal pin 81 in the of both parts 61 formed groove 63 at the bottom are the spring bows 72 pressed apart or the teeth 73 dissolved, whereby a disassembly is possible. Both parts have a beveled flank on the part projecting from the dovetail groove 62 so that together they can fix a workpiece with dovetail formation arranged transversely to the dovetail groove in a freely selectable position. The two parts 61 of the ridge system can in their final position by means of a pin 64 be secured in position. The production takes place by injection molding, preferably from renewable raw materials (bioplastic).

In the embodiment according to the 9 and 10 the trowel system has two identical parts 91 on, with a part rotated 180 degrees. Both parts fit together wedge-shaped (see position 101 ), are on the outside flanks 92 but aligned parallel to each other so that together they form a solid construction by mutual displacement in a mating dovetail groove. The protruding from the dovetail groove part has a T-shape 102 in order to fix planking, which are aligned transversely to the dovetail groove and have a corresponding shaping. The production of the ridged system is done by injection molding, preferably from renewable raw materials (bioplastic).

In the embodiment according to 11 The two-sided ridge system has three parts, the two outer parts 111 on the inner flanks 113 run in a wedge shape, on the outer edges 112 but are aligned parallel to each other. The exterior parts 111 are rounded off on one side (see position 115 ) so that they fit into a dovetail groove with a blind hole end and by inserting the wedge 114 form a solid construction. The strength of the ridge rail is increased by the fact that the wood fibers stand upright in the dovetail groove. Since wood is particularly tear-resistant in the direction of the grain, the force for joining the workpieces thereby increases by a multiple.

Using the above-mentioned ridge system, three-ply walls can be built, which guarantee a firm connection between the individual layers. These are preferably rotated in their fiber direction in each case by 90 degrees.

The 12 shows the structure of a three-ply solid wood wall with symmetrical structure of the wood layers. The planks 123 in the middle position are on both sides with a dovetail groove 122 provided in the longitudinal direction of the screed. The planks 124 In the outer layers, however, have dovetail grooves transverse to the screed. The fixation of the planks in each case in the middle of their width, using the above-mentioned Gratleistensystems 121 , shifts the effects of natural swelling or shrinkage in the ridge joints 125 between the individual planks. This avoids distortions in the overall construction. The position of the planks 123 in the middle position is the distance of the milling in the outer planks 124 specified. The position of the planks 124 in the outer layers is through the use of a suitable thorn 16 (please refer 1 ) fixed in the predetermined position. The above-mentioned grate system is preferably limited to the width of a screed with cross-milled dovetail groove. This allows each screed mounted in a simple manner and fixed exactly in the predetermined position.

Using the above-mentioned ridge system, five- or multi-layer walls can be built, which guarantee a firm connection between the individual layers. These are preferably rotated in their fiber direction in each case by 90 degrees.

The 13 shows the construction of a five-ply solid wood wall with symmetrical structure of the wood layers. The planks 133 in the middle position are provided on both sides with a dovetail groove in the longitudinal direction of the screed. The subsequent planks 135 pointing in the direction of the middle layer 133 Swallowtail grooves across the screed. Towards the outer layers are the Schwalbenschwanznuten 132 directed along the screed. The planks 134 the two outer layers have on the inside again dovetail grooves transverse to the screed. The fixation of the planks in each case in the middle of their width, using the above-mentioned Gratleistensystems 131 , shifts the effects of natural swelling or shrinkage in the ridge joints 136 between the individual planks. This avoids distortions in the overall construction. The position of the planks 133 in the middle position is given by the distance of the milling in the outer planks. The position of the planks in the outer layers is determined by the use of a suitable mandrel 16 (please refer 1 ) fixed in the predetermined position. The above-mentioned grate system is preferably limited to the width of a screed with cross-milled dovetail groove. This allows each screed mounted in a simple manner and fixed exactly in the predetermined position.

Using the above-mentioned lattice system multi-layer walls can be built, which guarantee a firm connection between the individual layers. These are preferably rotated in their fiber direction in each case by 90 degrees.

The 14 shows a five-ply wall with one-sided construction, wherein the number of layers is basically arbitrary. The construction starts with a layer of planks 141 with a one-sided milling a Schwalbenschwanznute in the longitudinal direction, which faces the following situation. The Bohlen 142 all other layers have on one side dovetail grooves transverse to the screed and on the other side a Schwalbenschwanznute in the longitudinal direction. Each ply is placed inwardly with the transversely aligned dovetail grooves, and forms outwardly with the longitudinally aligned dovetail groove the base for the subsequent ply. Exception is the outermost layer 143 , which is provided only on one side with dovetail grooves across the board. The fixation of the planks each in the middle of their width, using the above-mentioned ridge system, shifts the effects of natural swelling or shrinkage in the comb joints between the individual planks. This avoids distortions in the overall construction. The position of the planks in the middle position is determined by the distance of the milling in the outer planks. The position of the planks in the outer layers is determined by the use of a suitable mandrel 16 (please refer 1 ) fixed in the predetermined position. The above-mentioned grate system is preferably limited to the width of a screed with cross-milled dovetail groove. This allows each screed mounted in a simple manner and fixed exactly in the predetermined position.

Using the above-mentioned lattice system three- or multi-layer walls can be built, in which a central layer is formed for receiving sound insulation material.

The 15 shows a wall, where the middle layer of scantlings 153 which exists on both sides with a dovetail groove 151 are provided. The scantlings 153 are mounted at a suitable distance from each other to accommodate the sound insulation material can. The subsequent planks 152 point in the direction of the scantlings 153 Dovetail grooves transverse to the plank longitudinal direction, whose distance from each other and the position of the scantlings 153 pretends. The position of the planks 152 is through the use of a suitable thorn 16 (please refer 1 ) secured.

According to the 16 and 17 can be made using the ridge strip system according to 11 , three- or multi-layer walls are interconnected. Due to the bag-shaped milled recess of the dovetail grooves 162 in the walls have the outer elements of the lattice system 161 the desired depth stop. Preferably, the ridge system closes 161 flush with the wall plane (see position 171 ); however, a return can be specified as desired. Through the frontal milling of the dovetail grooves 162 in the horizontally running planks 163 In the middle layer, these clasp the rafter system like a prong and ensure a permanent and strong connection. The strength of the ridge system 161 is increased by the wood fibers standing upright in the dovetail groove. Since wood is particularly tear-resistant in the direction of the grain, the force for joining the workpieces thereby increases by a multiple. The 16 shows a three-ply wall with front blind holes 162 and inserted ridge strips.

The 17 shows multi-ply walls that recede using the ridged system 11 can be interconnected. Due to the bag-shaped milling of the dovetail grooves in the walls, the outer elements of the free-fall system have the desired depth stop. Preferably, the ridge system concludes so flush with the wall level, but also a return can be specified as desired. Due to the front-side milling of the dovetail grooves in the horizontally extending planks of the middle layer, these clasp the ridge system like a tine and ensure a permanent and strong connection. The strength of the lattice system is increased by the wood fibers standing upright in the dovetail groove. Since wood is particularly tear-resistant in the direction of the grain, the force for joining the workpieces thereby increases by a multiple. Another advantage is the possibility of a later - possibly necessary - disassembly of a structural unit.

To 18 can use wood shells 184 by means of the ridge system 181 according to the 6 to 8th be attached to solid wood walls or planks. The wall or the planks are doing with a dovetail groove 183 , the scrapers 184 with a swallowtail training 186 Mistake. This will allow the scantlings 184 in any position along the dovetail groove 183 be attached.

Further, after 18 planking 187 by means of the ridge system 182 according to the 9 and 10 on wooden scantlings 184 or solid wood walls. These are done with a dovetail groove 185 Mistake. The planking 187 will be at the butt joints with a ridge system 182 according to the 9 and 10 corresponding groove 188 Mistake.
