Description

The invention relates to a connecting device specified in the protection claim 1 type for connecting a first timber component and a transverse thereto, second timber component. Furthermore, the invention according to protection claim 9 relates to a connection arrangement with such a connection device.

Producing rigid connections between two wooden elements is nowadays particularly difficult in timber construction. However, such rigid connections are desirable, in particular with regard to a particularly aesthetic design language but also with regard to a particularly efficient use of materials. Since wood as a building material has a pronounced, orthotropic material behavior, it is particularly difficult to produce the rigid connection, since an occurring bending moment between the two wood components to be connected over a usually very small area or a very small lever arm must be transmitted. For smaller construction jobs, such as the construction of a carport, forces of more than 250 kN are generated. In connections made by conventional construction methods, such forces often can not be transferred without damage. In order to master this problem, these connections have been realized more and more often by dowel circles in the recent past. However, then there is the disadvantage that damage to the construction, for example transverse tensile failure, occur because the wood has a particularly pronounced swelling and swelling behavior.

It is therefore the object of the present invention to transfer forces and moments occurring in a timber construction at a connection of two timber components in a particularly efficient manner.

This object is achieved by a connecting device with the features of the protection claim 1. Furthermore, this object is achieved by a connection arrangement with the features of the protection claim 9.

Advantageous embodiments with expedient developments of the invention are specified in the other claims. Advantages and advantageous embodiments of the connecting device according to the invention are to be regarded as advantages and advantageous embodiments of the connection arrangement according to the invention and vice versa.

According to the invention, a connecting device is provided for connecting a first timber component and a second timber component extending transversely thereto. It is to be understood that a longitudinal direction of the first timber component and a longitudinal direction of the second timber component are mutually perpendicular, so that in a respective sectional image of the timber components respective grain lines of the first timber component and respective grain lines of the second timber component at least substantially transverse to each other.

The connecting device has a first fitting which can be connected to the first timber component and a second fitting which can be connected to the second timber component. The first fitting and / or the second fitting may each be made of a different material from wood. For example, the respective material of the two fittings may comprise a metallic material, for example steel, or may be made entirely of it.

The first fitting and the second fitting are fastened or fastened to each other by means of a first predetermined fastening unit. This means that the first timber component and the second timber component can be connected to each other via the connecting device by the first fitting and the second fitting are fastened to each other. In other words, the two timber components can be connected to one another indirectly via the connecting device.

In order to transmit forces and moments occurring in a timber construction at a juncture of two wooden components particularly efficiently, the invention provides that the first fitting of the connecting device and a rod against a longitudinal axis along a rod of the rod are connected or connected by means of a second predetermined fastening unit. Here, the rod is adapted to engage in a formed in the first wooden component, thread-free hole, wherein a longitudinal axis of the unthreaded hole and the longitudinal axis of the rod coincide at least substantially with each other. Further, an outer peripheral surface of the rod and an inner circumferential surface of the unthreaded hole may directly adjoin one another so that the rod in the unthreaded hole is prevented from rotating about a radius of the rod and / or against translational movement along the radius of the rod. Particularly preferably, an outer diameter of the rod and an inner diameter of the hole correspond at least substantially. Preferably, the rod and the unthreaded hole each have a circular cross-section.

This means that the second predetermined fastening unit may be formed as a plug connection, wherein the rod in the unthreaded hole of the first timber component is pluggable. However, it is particularly preferred, in particular, to be able to transmit higher forces and / or moments than by means of the pure plug-in connection if the second predetermined fastening unit comprises an adhesive, via which or by means of which the rod can be glued into the unthreaded hole of the first timber component ,

The connecting device may comprise at least one further rod, in particular three further rods, which are each designed to engage in a respective, unthreaded hole of the first timber component.

In the case of the connecting device according to the invention, the forces and / or moments between the two timber components are transmitted at least partially via at least one pin-shaped connecting means, that is to say via the rod. By the rod or rods each engaging or engaging in the first wooden component in a particularly expansive manner, that is to say deeply, a particularly long load path is created, via which the forces and / or moments occurring in the timber construction are particularly efficient between the two timber components can be transmitted. Here, the resulting forces, for example tensile and / or compressive forces, particularly advantageously parallel to a grain direction or fiber direction of the first timber component can be introduced into this, wherein it can be provided that the first timber component is designed as a support.

By virtue of the second fastening unit comprising an adhesive, it is ensured that the forces and / or moments occurring in the timber construction are transmitted along a major part of a longitudinal extension of the rod. In a comparison of the adhesive bond with a conventional screw, wherein the rod is formed as a threaded rod and the hole formed in the first timber member having an internal thread, which corresponds to the thread of the rod, stands for the transmission of forces and / or moments between the Both wood components a larger transmission range available because only a fraction of the threads are involved in a force and / or torque transmission in a threaded connection.

It has been found to be particularly advantageous that the rod has a rib structure on its outer peripheral surface. This means that the rod has a larger outer peripheral surface due to the rib structure than when the rod follows the outside of a shape of a regular circular cylinder. As a result, the transmission region is designed to be even larger due to a larger outer surface of the rod provided with the rib structure for transmitting the forces and / or moments.

Furthermore, it has proven to be advantageous for the second fastening unit to have an external thread on the rod and an internal thread on the first fitting. In other words, the rod and the first fitting are fastened together by means of a threaded connection. For this purpose, the external thread of the rod and the internal thread of the first fitting correspond to each other, so that in the connecting device, the rod and the first fitting are screwed or screwed together.

In a particularly advantageous embodiment of the connecting device, the rib structure is at least partially formed by the external thread of the rod. For example, the external thread may at least largely or completely extend over a longitudinal extent of the rod. In view of a particularly simple or low-cost manufacture of the connecting device, the rod may be formed in this case as a commercially available, conventional threaded rod. As a result, the connecting device can be adapted particularly advantageously to a respective timber construction to be constructed by the rod which can be inserted or inserted in the connecting device being produced by simply cutting the conventional threaded rod into a design of the connecting device.

An end face of one of the two timber components and a side face of the corresponding other timber component may together form a common end face. In order to be able to transmit forces and / or moments occurring particularly efficiently in such a positional arrangement of the two timber components in the timber construction at the junction of the two timber components, the connecting device may have a third fitting. The third fitting has a first receptacle into which the first fitting can be inserted or inserted. Furthermore, the third fitting has a second receptacle into which the second fitting can be inserted or inserted. This means that the first fitting and the second fitting in a fastened state, in particular in the finished timber construction, in the third fitting inserted or inserted. It can be provided, for example, that the third fitting is part of the first fastening unit. In other words, the first fitting and the second fitting can be fastened or fastened to one another by means of the third fitting.

According to another embodiment, the connecting device has a Alignment on, by means of which the first fitting and the second fitting are positionally latched or latched relative to each other. This is advantageous in that the two fittings relative to each other are particularly easy to align, whereby the connecting device is particularly easy to handle. In producing the fastened state of the first and the second fitting, an unintentional slipping or shifting of the first fitting with respect to the second fitting is effectively prevented.

It is particularly preferred that an engaging in a locking receptacle of the second fitting and protruding from the first fitting locking element of the alignment is formed by the rod, in particular the threaded rod. For example, for this purpose, the rod can be screwed through the first fitting, so that it extends on both sides of the first fitting. Thus, the rod can protrude beyond a contact surface of the first fitting, which is adapted to directly adjoin the second fitting. A portion of the rod, which protrudes from the contact surface, then forms the locking element. The latching receptacle can be embodied, for example, as a thread-free hole formed in a base plate of the second fitting, which corresponds to a diameter of the external thread of the rod, so that the rod can be engaged in the hole without the intermediary of a threaded connection, whereby the first and the second fitting are particularly strong easy and efficient positionally secure to each other.

In order to form the second fitting of the connecting device particularly resistant to bending, according to another embodiment, the second fitting may comprise a mounting plate and at least one web projecting therefrom. The attachment plate may be, for example, the base plate. Due to the particular vertically projecting from the mounting plate or base web, the second fitting has a particularly high moment of area moment of inertia, which results in a particularly high resistance to bending of the first fitting about a transverse axis of the first fitting.

As a result, the connecting device is particularly stable due to the particularly rigid fitting so that even higher forces and / or moments of timber construction can be transferred via the connecting device.

The invention further relates to a connection arrangement of the first timber component and the transversely extending second timber component, with a connecting device described hereinbefore. In the connection arrangement, the first fitting is connected to the first timber component and the second fitting is connected to the second timber component. Furthermore, the first fitting and the second fitting are attached to each other.

In order to transmit forces and moments occurring in the timber construction at the juncture of the two timber components particularly efficiently, it is provided in the connection arrangement according to the invention that the rod along a longitudinal direction of the first timber component engages in the thread-free hole formed therein, where the rod by means of a Adhesive is glued to the first timber component. In other words, in the connection arrangement, the connection device is used, in which the second fastening unit has the adhesive or in which the second fastening unit is formed by the adhesive.

By means of the connection arrangement, the forces and / or moments occurring in the finished timber construction are transferable in a particularly efficient manner at the connection point where the first timber component and the second timber component adjoin one another.

In the connection arrangement, it has been found to be particularly advantageous that the second fitting of the connecting device is at least partially embedded in the second wooden component. This results in, for example, the advantage that in a dimensional determination in a planning phase for the timber construction of the second fitting in the dimensioning of the second timber component is not considered. This means that the connection arrangement can be integrated in an existing design plan of the timber construction with particularly little effort, at least in the planning phase. Furthermore, the second or fully embedded in the second timber component or second fitting has a double functionality by reinforced in the connection arrangement of the second fitting the second timber component, in particular against bending about a transverse axis of the timber component. Furthermore, the second fitting does not protrude beyond an area of the second timber component, so that a particularly pleasing, step-free surface of the second timber component can be ensured.

In a particularly advantageous embodiment, the first fitting and the second fitting of the connecting device are fastened to one another via a connecting bracket of the first fitting, which protrudes beyond an edge of the first timber component parallel to a support surface between the two timber components. That means the first one Fastening unit can be arranged wholly or partially in a region of the connection console. This has the consequence that the first attachment unit is particularly easy to reach, so that the first fitting and the second fitting or the first timber component and the second timber component are to be attached to each other particularly little effort. Likewise, the two timber components or the first fitting and the second fitting are particularly easy to disassemble from each other because the first attachment unit is particularly easy to reach via the connection console.

It has proved to be further advantageous that the first fitting and the second fitting of the connecting device are fastened to one another via the first fastening unit, which comprises at least one screw connection. This means that the first fastening unit may have a screw connection or a plurality of screw connections, for example such that a hole provided with an internal thread is formed in the base plate or fastening plate of the second fitting. A longitudinal center axis of the threaded hole in the base plate or mounting plate of the second fitting and a longitudinal center axis of a threaded example formed hole of the first fitting then coincide. Thus, the first fitting and the second fitting by means of a screw known per se, for example, hexagon screw, screwed together. This is advantageous insofar as the screw connection is particularly easy to implement, wherein the screw, if necessary, again is particularly easy to solve.

If the connection arrangement is used in a timber construction, wherein an end face of one of the two timber components and a side face of the corresponding other timber component together form a common end face, the connection device may comprise the third fitting. It is then of particular advantage that a first end of the first fitting and the second fitting are connected to each other via the first fastening unit and a first end opposite the first end of the first fitting and the second fitting on the third fitting together and in relation to the two wooden components are fixed. For this purpose, the first fitting and the second fitting engage in the third fitting, in particular in the corresponding receptacles, and the third fitting is fastened to the two timber components by means of a third fastening unit. In this way, the two timber components are arranged in compliance with the advantages described above in a corner joint to each other.

In the figures, identical or functionally identical elements are provided with the same reference numerals.

The following will be a connection arrangement 1 and a connection device 2 described in a common description of the figures. 1 shows a sectional view of the connection arrangement 1 for a support connection of a first timber component 3 and a second timber component 4 with the connection device 2 , The corresponding section line is with BB in 3 located. The first wooden construction element 3 and the second timber component 4 run transversely to each other, that is, a grain or fiber direction 5 of the first timber component 3 and a grain or fiber direction 6 of the second timber component 4 are arranged transversely to each other. That means that the first wooden construction element 3 a support for the second timber component 4 can form.

The at the connection arrangement 1 used connection device 2 has a first fitting 7 on, which with the first wooden component 3 is firmly connected. To ensure that the first fitting 7 and the first wooden construction element 3 are held fixed to each other positionally, it can be provided that the first fitting 7 by means of at least one, in this case two wood screws 8th with the first wooden construction element 3 is screwed.

The connection device 2 or the connection arrangement 1 also has a second fitting 9 on which in turn a base or mounting plate 10 having. The second fitting 9 and the first fitting 7 borders via an outside contact surface 11 of the second fitting 9 and an inside contact surface 12 of the first fitting 7 directly to each other. That means that the first wooden construction element 3 and the second timber component 4 indirectly via the connection device 2 or over the two fittings 7 . 9 adjoin one another. This forms the contact surface 12 a support surface on which the second timber component 4 over the second fitting 9 is supported.

In the present example, the second fitting is 9 in the second timber component 4 embedded. For example, the second timber component 4 be provided with a material recess whose shape at least substantially an outer contour of the second fitting 9 equivalent. In other words, the second fitting 9 such in the second timber component 4 be sunk that the second fitting 9 not from an outer contour of the second timber component 4 protrudes.

To the second fitting 9 particularly reliable with the second timber component 4 to connect, it is provided that the second fitting 9 in a conventional manner with the second timber component 4 is screwed. This can be a variety of other wood screws 13 be provided, which in each case the second fitting 9 completely and the second wooden construction element 4 partially, in particular for the most part, penetrate. By the wood screws 13 the second wooden construction element 4 penetrate mostly, is an undesirable splitting of the second timber component 4 counteracted particularly effectively.

Alternatively or in addition to the wood screw 13 or to the wood screws 13 can the second fitting 9 and the second timber component 4 be joined together by a threaded bolt 14 the second fitting 9 and the second timber component 4 completely penetrating and at a top 15 of the second timber component 4 as well as at the contact surface 11 of the second fitting 9 for example by means of a nut 16 , is screwed.

To a relative movement of the two timber construction elements 3 . 4 to prevent each other are in the connection device 2 the two fittings 7 . 9 via a first predetermined fastening unit 17 connectable or connected with each other. For this purpose, the first fastening unit 17 a screw connection 18 or more screw connections 18 , in the present case four screw connections 18 , exhibit. In particular, the second fitting 9 having an internally threaded hole, which with an external thread of a cap screw 19 , in particular a hexagon screw, corresponds. A longitudinal center axis 20 the threaded hole of the second fitting 9 and a longitudinal center axis 21 one in the first fitting 7 trained holes fall together, so that by means of the first fitting 7 into the threaded hole of the second fitting 9 hineinestreckenden capscrew or hexagon screw 19 the first fitting 7 between the contact surface 11 the first fitting and the head screw head 19 is tense. In other words, the first fitting 7 and the second fitting 9 bolted together or screwed by the external thread of the cap screw 19 in the internal thread of the threaded hole of the second fitting 9 intervenes.

In order to ensure a particularly efficient transfer of forces and / or moments, which in a timber construction at the in 1 shown connection point, in particular between the two timber components 3 . 4 , occur is a pole 22 provided, which in relation to a longitudinal axis 23 the pole 22 non-slip with the first fitting 7 connectable or connected. In the connection device 2 can be the first fitting 7 and the pole 22 be connectable or connected to each other while in the connection arrangement 1 the fitting 7 and the pole 22 connected to each other. For this purpose, a second predetermined fastening unit 24 provided over which the rod 22 and the first fitting 7 each other positively, positively and / or materially connected to each other. So can the rod 22 and the first fitting 7 For example, be welded together, glued, etc. In the present example, the second fastening unit 24 an external thread on the rod 22 and an internal thread on the first fitting 7 on, wherein the external thread and the internal thread correspond with each other, so that the rod 22 through the intermediary of a threaded connection in the first fitting 7 can be screwed or screwed. The internal thread of the first fitting 7 is in a hole 25 formed, which in the present example the particular plate-shaped, first fitting 7 completely penetrates.

In the connection arrangement 1 has the first timber component 3 a blind hole 26 on, whose length and contour at least substantially a length and an outer contour of the rod 22 correspond. Positionally, the blind hole 26 of the first timber component 3 arranged such that the longitudinal axis 23 the pole 22 and a longitudinal center axis 27 , for example a drilling axis, of the blind hole 26 coincide with each other. Accordingly, the rod attacks 22 in the blind hole 26 that is, in the first timber component 3 , one. An inner diameter of the blind hole 26 and an outer diameter of the rod 22 each may be formed so that an outer peripheral surface 28 the pole 22 and an inner peripheral surface 29 the blind hole 26 directly adjacent to each other. However, it is particularly preferred if between the outer peripheral surface 28 and the inner peripheral surface 29 a gap is formed.

In the present example, the rod 22 and the first wooden construction element 3 in the connection arrangement 1 by means of an adhesive 30 glued together. In a building of the timber construction, in which the connection arrangement 1 is used, for example, be provided that first the rod 22 in the blind hole 26 is arranged and then between the outer peripheral surface 28 and the inner peripheral surface 29 formed gap by means of an adhesive, that is, by means of the adhesive 30 , filled in or refilled. But it is also conceivable that initially the blind hole 26 , at least in part, with the adhesive 30 is filled and then the rod in the blind hole 26 arranged, for example, inserted, which causes the adhesive 30 off the rack 22 is displaced and subsequently the gap between the inner peripheral surface 29 and the outer peripheral surface 28 fills.

For a particularly reliable adhesive connection between the rod 22 and the first timber component 3 to ensure the pole is pointing 22 on the outer peripheral surface 28 a rib structure 31 on. The rib structure 31 may be formed, for example, as in a well-known from the prior art reinforcing steel. The rib structure 31 on the outer peripheral surface 28 As a result, the outer peripheral surface 28 the pole 22 is greater than a rod which has a circular or annular cross-section over its entire longitudinal extent. As a result, a particularly large adhesive surface is created, so that the adhesive 30 over the particularly large adhesive surface with the rod 22 is in contact, so that particularly high forces and / or moments between the two timber components 3 . 4 are transferable. In the present example is the rod 22 formed as a threaded rod whose external thread extends over an entire longitudinal extent of the rod 22 extends. This means that the external thread of the threaded rod 22 or the rod 22 has a dual functionality. First, the external thread of the rod 22 Part of the second fastening unit 24 , by means of which the rod 22 and the first fitting 7 connected to each other. Second, by means of the external thread of the threaded rod 22 the rib structure 31 formed as the external thread, as described above, the surface of the rod 22 enlarged in comparison to a circular cylindrical or circular cylindrical trained rod.

The second fitting 9 the connection arrangement 1 or the connecting device 2 is in a sectional view along the in 1 shown section line AA in 2 shown. It is in the 2 particularly good to realize that the second fitting, which is the mounting plate 10 or the base plate 10 has, at least one of which projecting web 32 having. That means the second fitting 9 at least substantially may have a T-shaped cross-section. Here is the bridge 32 parallel and centered with respect to the base plate 10 arranged. The base plate 10 and the jetty 32 can each other the second fitting 9 form. For this purpose, the bridge 32 and the base plate or mounting plate 10 be connected to each other force, shape and / or cohesive with each other. Furthermore, the bridge can 32 and the mounting plate 10 be formed integrally with each other. It is also conceivable that the second fitting 9 several bars 32 having. Due to the footbridge 32 or due to the webs 32 is the second fitting 9 particularly stable against bending around a transverse axis 33 of the second fitting 9 formed, with the transverse axis 33 of the second fitting 9 and a transverse axis 34 of the second timber component 4 can coincide. In this way, the second timber component 4 by means of the second fitting embedded therein 9 particularly stable against bending around the transverse axis 34 educated.

In 3 where is a sectional view of the connection assembly 1 along the in 1 is shown particularly well an alignment unit 35 to recognize, by means of which the first fitting 7 and the second fitting 9 Positionally latched or locked relative to each other. The alignment unit 35 has a locking receptacle 36 on which at the second fitting 9 is arranged. In the present case, this is a in the base plate 10 trained hole, which is the base plate 10 penetrates in whole or in part. A longitudinal center axis 27 the hole of the detent receptacle 36 and the longitudinal axis 23 the pole 22 fall together. Furthermore, the hole of the locking receptacle 36 an inner diameter, which with the outer diameter of the rod 22 corresponds.

By the bar 22 in the present example, with the first fitting 7 screwed that is the rod 22 over the contact surface 12 of the first fitting 7 extends out, forms the rod 22 by means of the over the contact surface 12 In addition, extending portion a locking element 37 the alignment unit 35 , As the inner diameter of the hole of the locking receptacle 36 and the outside diameter of the rod 22 so correspond to each other that the rod 22 into the hole of the locking receptacle 36 can intervene without the intervention of a threaded connection, which is over the contact surface 12 extending portion of the rod 22 particularly easy in the hole, that is in the locking receptacle 36 , engageable. In this way, the first fitting 7 and the second fitting 9 in making the connection assembly 1 particularly fast and easy to align with each other.

So far, it has been described how by means of the connecting device 2 or by means of the connection arrangement 1 the support connection between the two timber components 3 . 4 is constructed. The connection arrangement according to the invention 1 and / or the connecting device according to the invention 2 but can / can also with a corner joint between the two wood components 3 . 4 be used. Such a corner joint is in 4 shown where a sectional view of the connection assembly 1 for the corner joint of the two wooden construction elements 3 . 4 with the connection device 2 along an in 6 shown section line DD is shown. In contrast to the support connection described so far form an end face 38 one of the two wooden construction elements 3 . 4 and a parallel side surface 39 the corresponding other wooden component 3 . 4 together a common, step-free formed end surface 40 , In the present example for the corner joint forms the first timber component 3 the support for the second timber component 4 so the frontal area 38 of the second timber component 4 along with the side surface 39 of the first timber component 3 with each other, the steplessly formed end surface 40 form. The connection device 2 has a third fitting for this purpose 41 which is in a front view of the connection arrangement 1 or the connecting device 2 in 5 is shown. The third fitting has a first shot 42 on, in which the first fitting 7 is pluggable. Furthermore, the third fitting 41 a second shot 43 into which the second fitting 9 is pluggable. That means the two fittings 7 . 9 in a fastened state, for example in the connection arrangement 1 , in the third fitting 41 are plugged in.

Correspondingly, in the corner connection, a first end 44 and the second fitting 9 over the previously described, first fastening unit 17 connected with each other. The first attachment unit 17 the corner connection or the support connection has a connection console 45 on which parallel to the contact surfaces 11 . 12 runs and between the two wooden construction elements 3 . 4 over a border 46 of the first timber component 3 survives. In other words, it's the first end 44 of the first fitting 7 over a distance 47 from the edge 46 of the first timber component 3 spaced so that between the first end 44 and the edge 46 the connection console 45 is trained. With reference to 1 is to be understood that also a second end 48 of the first fitting 7 from the first timber component 3 can be spaced, so that in the support connection between the two timber components 3 . 4 on both sides of the first timber component 3 the connection console 45 can be trained.

At the in 4 shown corner joint is the second end 48 of the first fitting 7 formed as a tab, which with the first receptacle 42 corresponds, so that the first fitting 7 over its tab and over the first shot 42 in the third fitting 41 intervenes. A first end 49 of the second fitting 9 is formed at the corner joint at least substantially the same as the first end 49 of the fitting 9 according to the in 1 shown support connection. Like the first end 44 and the second end 48 of the first fitting 7 are opposite, are also the first end 49 and a second end 50 of the second fitting 9 across from. In the present example, the second end 50 of the second fitting 9 at the corner joint also formed as a tab, which with the second receptacle 43 of the third fitting 41 corresponds, so that the second fitting 9 over its tab and over the second shot 43 in the third fitting 41 is plugged in.

So it's in 4 shown as the second end 48 of the first fitting 7 and the second fitting 9 over the third fitting 41 are fixed to each other. To the connecting device 2 that means the fittings 7 . 9 . 41 , in relation to the two wooden construction elements 3 . 4 to fix, is a third fixing unit 51 provided over which the third fitting 41 on the two wooden construction elements 3 . 4 is attached. In the present example, the third fastening unit 51 of the third fitting 41 a lot of holes 52 on which the fitting 41 penetrate obliquely and completely. In an assembled state of the connection device 2 if this at the corner joint performing connection arrangement 1 is used, so by means of the third fitting 41 the two fittings 7 . 9 to each other and the connecting device 2 on the two wooden construction elements 3 . 4 fixed.

The connection arrangement 1 or the connection device 2 can or can therefore be used in each case in a support connection as well as in a corner joint of a wooden structure. In this case, the respective connection arrangements differ 1 or the respective connection devices 2 only in the way a respective second end 48 . 50 the two fittings 7 . 9 in relation to each other and in relation to the two wooden construction elements 3 . 4 are attached.

With reference to 5 It should be noted that a width of the third fitting 41 at least substantially a width of the at the connection arrangement 1 involved timber construction elements 3 . 4 can correspond. It is also conceivable that the fitting 41 has a smaller width than the timber components 3 . 4 , In addition - and how in 4 recognizable - can the third fitting 41 in the two wooden construction elements 3 . 4 be embedded. For this purpose, the two wood components 3 . 4 each having a material recess, so that the third fitting 41 partly in the first wooden construction element 3 and partly in the second timber component 4 is embedded. A depth of the respective material recess advantageously corresponds to a thickness or thickness of the third fitting 41 so one of the wooden components 3 . 4 remote surface of the third fitting 41 together with the face 38 and the side surface 39 the common termination area 40 is formed.
