Furthermore, the invention relates a system of interconnected components.

A composite anchor of this type, which is used for the production of, for example, a structural structure, as well as a system of interconnected components is known from DE 197 01 458 C1 known.

To This type of structure structures are made for different Applications suitable. They are used in the construction of buildings as well used as in trade fair and stage construction or for example in the construction of roller coasters. The system composite anchor and cooperating components is designed to that the static and dynamic loads acting on the structure can be included. It comes besides the stability of the individual carriers and Support in particular also that the forces occurring at the Securely transfer nodes from interconnected supports or columns become.

One another aspect of such systems is their economics, d. H. that they are simple and inexpensive to manufacture and assemble are. In many cases it is also desirable that the composite system gives a pleasant aesthetic impression.

One typical example of The constructions mentioned here is the wooden building construction in which Beams or the like supporting elements to each other to sustainable wall, Floor and / or roof structures are connected. There are also different Material combinations are used, i. the material wood can with concrete, for example as filling material, as well as being combined with plastic or metal parts. For the material Wood come full wood, Glued laminated timber and other wood-based materials in question, with the full woods in particular in the form of roundwoods, Beams, squared lumber, Boards and crossbars can be designed compared to Size of her Cross section relatively high forces record and transmit are able to. A crossbar is understood here as a bar, by slitting one or more tree trunks and turning the cuts around its longitudinal axis and subsequent Connecting these parts to a new bar is formed, taking through the then inside, originally the outer parts of the tree or the trees forming arched surfaces a substantially centrally extending longitudinally through the cross bar opening is formed.

Links, especially in the area of the ends of these components, are variously developed and introduced to the practice Service. Here are just a few examples of known options indicated, such. B. transversely to the longitudinal axis of the beam in the range of groove and spring connections driven dowels with bolts and additional Screw nails or brand connections with cover plates or cones with transverse hardwood dowels or inset T-steel with dowels or cones, in particular journals and the like. More. frontal connections can known be achieved by a so-called beam impact, in which by means of transverse dowels special design, the beam sides in the region of their ends on both sides with supporting parts for power transmission are occupied.

From the already mentioned DE 197 01 458 C1 is a timber construction connection for the front-side connecting a crossbar known. It has a composite anchor, which is embedded in at least a portion of an opening extending within the crossbar along its entire length, in such a way that it is set back with its outer end opposite the beam end face. The composite anchor has a rod-shaped core with projecting spikes and at least one of the core ends a connection option.

With This wood connection is possible with a minimum number of components with low installation costs a visually appealing, frontal connection of a crossbar to create with another component. However, it is with this prior art wood connection not readily possible, a complete Structure to build, as they primarily for the frontal use designed in a crossbar.

From the DE 100 29 343 C2 a similar composite system for beam-shaped components is known in which it is provided that the composite anchor is provided with a through recess through which a connecting means extends freely longitudinally movable and engages in a counterpart embedded in a component counterpart. This ensures that a simplified and thus cost-effective attachment of the equipped with a composite anchor bar to any connection elements is possible.

The DE 203 06 942 U1 also uses generic composite anchors for producing a composite of several components. In order to produce a plurality of different connection nodes with few parts, with a simple mounting option is sought, it is provided here that the composite anchor next to the connection option for a first component has at least one connection option for another component, the obliquely or transversely in one direction is aligned with the first component and cooperates via an opening in the first component with a connection possibility of the other component.

In 1 is a construction shown that consists of three components 1 . 2 . 3 exists, which are firmly connected to each other via a compound anchor system. The component 1 is a one-piece wooden beam, which has a transverse bore. The two components 2 and 3 However, are formed as split in longitudinal section bars, ie they consist of sub-elements 2a and 2 B respectively. 3a and 3b ,

In every subelement 2a . 2 B . 3a . 3b recesses are incorporated, so that a composite anchor 4 respectively. 5 can be included. Every composite anchor 4 . 5 has thorns 6 on that in holes in the subelements 2a . 2 B . 3a . 3b of the components 2 . 3 intervention. After the composite anchor 4 . 5 in the recesses in the sub-element 2a respectively. 3a is inserted, the sub-elements 2a and 2 B respectively. 3a and 3b connected to each other, for example, glued, so that the composite anchor 4 . 5 firmly inside the device 2 . 3 is arranged.

In the present case are both composite anchors 4 . 5 provided with a longitudinal bore. Before connecting the sub-elements 2a and 2 B was still a fixing screw 7 used. This lies with her head 8th at the axial end of the composite anchor 4 on and interspersed both the composite anchor 4 as well as the component 1 and the composite anchor 5 to get into a - not shown - thread in the composite anchor 5 intervene.

Will the screw 7 then over an opening 9 tightened with an angle tool, a firm connection between the three components 1 . 2 . 3 produced.

This Construction principle is known in principle in the prior art.

In the embodiment according to 1 is new, however, that the composite anchor shown on the left in the figure 4 Although it is designed according to standard that the composite anchor shown on the right 5 However, has a bore which is partially provided with an internal thread, see below

This in 1 Outlined construction concept can be used in components of any nature. It can be used, for example, in crossbeams or in a wind band connection and other various configurations.

To facilitate the assembly of the system, a solution is advantageous, as in 2a and 2 B outlined. To recognize here is a two-part trained composite anchor 4 ie the composite anchor 4 consists of a part here 4a and a part 4b , Indicated is how the thorns 6 in recesses in two sub-elements 2a and 2 B intervention. The two parts 4a . 4b of the composite anchor 4 are on the side facing in the assembled state with a means 10 equipped for the positive and non-positive connection of the two parts, namely with one part of a tongue and groove system.

That part of the means 10 is through a dovetailed groove 11 formed, the other part by a correspondingly shaped spring 12 , The two parts 11 and 12 can be put together and then pushed into a direction of insertion E into each other. The swallowtail groove 11 thus forms an undercut for the spring 12 , so that both parts are immovable perpendicular to the insertion direction E. You can see it at the end of the spring 12 a small insertion bevel 13 ; equally is an insertion bevel 14 at the insertion opening of the groove 11 provided to the assembly process, ie the insertion of the spring 12 in the groove 11 to facilitate.

One too 2a and 2 B similar embodiment is in 3a and 3b to see. Basically, the same principle is realized here as it is in 2a . 2 B is shown. However, here is provided that the tongue and groove system 10 has an orientation transverse to the longitudinal axis L of the composite anchor 4 is oriented. Furthermore, spaced apart two tongue and groove systems 10 intended. Here are the two parts 4a and 4b of the composite anchor 4 in the transverse to the longitudinal axis L of the composite anchor 4 aligned insertion direction E are pushed into each other.

The groove 11 and the spring 12 can - as it is exemplarily in 3a is registered - be provided in the insertion direction E with a small cone angle α, in order to produce a non-positive bond when reaching the corresponding end position in addition to the positive connection NEN.

The two parts 4a . 4b The composite anchor can be firmly connected to each other by means of the dovetail tongue and groove connection after their insertion into the components. The insertion of the two composite anchor parts 4a and 4b in the components 2a respectively. 2 B can be done in a simple manner by the respective composite anchor parts by means of screws to the components 2a and 2 B be fixed. For this purpose, the two composite anchor parts 4a and 4b two unspecified holes on each.

The composite anchors 4 The type described can be used for the transmission of shear and shear forces and facilitate the production of prefabricated wood components (rod or sheet), which then z. B. with considerable ease of assembly at the construction site positively or non-positively assembled or pushed together.

In the 4 to 10 another embodiment of the inventive concept is illustrated. Just like in the 2 and 3 Here is the compound anchor 4 formed in two parts, ie it consists of the two parts 4a and 4b , wherein the division plane of the composite anchor 4 along the longitudinal axis L (s. 4 ) runs and this includes.

As it's best from the 6 to 9 it can be seen, are the two parts 4a and 4b of the composite anchor 4 each of holes 15 . 16 and 17 interspersed.

The hole 15 penetrates approximately in the middle of both parts 4a . 4b of the composite anchor 4 at an angle 45 ° to the longitudinal axis L, s. 6 and 7 ,

Meanwhile, the holes penetrate 16 and 17 the two parts 4a . 4b although also below 45 °, but to the direction Q transverse to the longitudinal axis L. Here is the one end of the composite anchor 4 arranged hole 16 in the opposite direction to that hole 17 arranged in the other end of the composite anchor 4 is arranged.

As it is best in 10 can be seen through the two juxtaposed parts 4a and 4b of the composite anchor 4 pin-shaped connecting elements 18 . 19 . 20 stuck to the two parts 4a . 4b firmly together. The connecting pin 18 gets into the hole 15 introduced the pins 19 and 20 into the holes 16 and 17 , By the arrangement of the holes 15 . 16 . 17 Angle is a firm connection between the parts 4a and 4b ,

In 10 is still to be recognized that more pens 21 and 22 can be inserted into corresponding bores which extend at an angle of 90 ° to the longitudinal axis L.

The in 11 in perspective and in 12 in sectional view shown composite anchor 4 is integrally formed and has a through hole 23 on, extending along the longitudinal axis L of the composite anchor 4 extends. The composite anchor 4 here is characterized by the fact that he has an internal thread 24 has, whose core diameter is smaller than the diameter of the through hole 23 , This gives the possibility of a bolt in 11 respectively. 12 from the right into the through hole 23 to let enter and its thread in the internal thread 24 screwed.

This bending moments can be taken in an improved way. There are in fact for himself in the hole 23 located bolt two points of support, namely one in the threaded area and one at the exit area of the bolt at the end of the composite anchor. By spacing the two support points moments can be better absorbed than is the case with previously known solutions. By passing the bolt through the hollow composite anchor and by screwing the bolt in the end located inside thread 24 creates a "change of criteria" to the "carrier on two supports". Through the input and end supports of the inserted bolt, the forces occurring are absorbed better over the located between the support points distance, so that so that higher forces and moments can be transmitted, as usual in previously known solutions.

When extending the internal thread 24 can - as with a backward to be screwed shear anchor - connect to a counterpart. This considerably increases the variety of applications due to the proposed embodiment. The composite anchor can - with appropriate choice of the thread in terms of its length - provide connectivity options from both sides.

The in the 13 to 20 solutions shown focus on further embodiments of the composite anchor, in which this is equipped with at least one flat-shaped connecting portion.

In 13 is a composite anchor 4 to see, the side each two flat-shaped connecting sections 25 having. The connecting sections 25 are at the same time as the composite anchor 4 poured, so that there is a one-piece composite.

Each connection section 25 has at least one hole 26 on, with which it is possible to screw the composite anchor on the surface of a component. Then the spikes protrude only in one direction into corresponding recesses in the component. Therefore, in the 13 to 20 sketched composite anchor 4 even with thorns 6 which extend in a direction away from the composite anchor body.

From the 15 and 16 goes out, by the way, that here too the through hole 23 is provided, the one-sided in the thread 24 passes.

The 17 to 19 show the composite anchor 4 in an alternative embodiment. Here is only a single surface trained holding section 27 is provided, which is oriented so that its surface normal N parallel to the longitudinal axis L of the composite anchor 4 runs.

The solution after 19 combines such a holding section 27 with the holding sections 25 that in the 13 to 16 you can see. The composite anchor 4 can both without (s. 17 . 18 ) as well as with through hole 23 - with and without thread 24 - Be provided (s. 19 ).

In 20 an application example is shown in which the composite anchor 4 to 17 respectively. 18 is used to two components 1 . 2 to connect with each other. The holding section 27 forms a solid support on the component 1 to the device 2 to fix relative to this. The definition of the holding section 27 done by screwing through holes 28 be screwed.

20 can be seen that it is possible with the composite anchor proposed here, in particular a wooden secondary beam to egg nem wood main carrier not visibly connect. The recesses for the spikes are inserted by means of a template in the face of the subcarrier in a known manner. The composite anchor is then fastened to the secondary beam with wooden construction screws, which are guided either directly through the body of the composite anchor or through the lateral retaining sections. The thus completed secondary beam is then on the main carrier by means of the front-side holding section 27 hung up and fastened there again with wooden construction screws. This creates a non-visible connection.

During the rotation of the composite anchor by 180 °, so that the holding section 27 z. B. would be placed on a concrete floor, it is possible, wooden stalks effectively and easy to install on z. B. connect the concrete surface or connect to this. This can also be done by means of dowels, which are performed by the cast or separate holding section instead of the timber screw. This type of composite anchor can be installed both in the production plant for the purpose of high prefabrication in individual stems or in stems that are already installed in finished wall surfaces, with the result that even complete wall surfaces already such foot parts, the z. B. can be connected to concrete surfaces, not visibly carry in itself.

The according to 13 to 20 proposed embodiments are particularly advantageous and preferred for the restoration of wooden structures.

In these solutions, it is of particular advantage that it is possible to fix the composite anchor laterally on a wooden support, ie it is not - as for example in 1 - the integrated conception is realized. The installation state of the composite anchor "only from outside" allows the attachment of the anchor to a one-piece wooden element in a very simple manner. For this purpose, the thorns are also provided pointing in one direction only.

It is with the composite anchor 4 according to the 13 to 20 So achieved the decisive advantage that an attachment of the anchor to a one-piece support is possible, from the outside.

In the 21 to 23 is seen as a system of components 1 . 2 and 3 in a simple manner by means of two composite anchors 4 can be connected to each other. The component 1 (Support) has a transverse bore for this purpose 29 on, through which a pipe 30 (preferably a steel pipe) can be plugged. Both compound anchors 4 are provided with a through hole along their longitudinal axis. The pipe 30 is chosen long enough that there are both compound anchors 4 completely interspersed and in addition still somewhat overhanging axially.

21 shows that the composite anchors 4 in the way it relates to 1 was explained in the components 2 respectively. 3 (Latches) are anchored. In 22 is outlined a preassembled installation situation in which the pipe 30 through the hole 29 in the component 1 is pushed through and the two components 2 and 3 laterally were set so that the pipe 30 both composite anchors 4 interspersed.

The fixation of the composite is done here by steel pins 31 that after the in 22 sketched pre-assembly can be driven in the manner shown.

How best 23 shows, is a preferably conical steel pen 31 so hammered that he is the device 1 including pipe 30 interspersed; that's the pipe 30 relative to the component 1 established.

The other two steel pins 31 become so across the components 2 and 3 driven that pipe 30 each directly in the axial end of the composite anchor 4 is enforced. This is the tube 30 also relative to the respective composite anchor 4 fixed, giving a total of the solid bond between the three components 1 . 2 . 3 is made.

Corresponding holes for the steel pins 31 in the components 1 . 2 respectively. 3 as well as possibly in the pipe can be mounted beforehand to facilitate the assembly. For example, the holes can be pre-drilled with a diameter of 5 mm and then driven steel pins with a diameter of 6 mm. Finally, the inlet holes of the steel pins can be closed with wooden plugs.

The proposal according to 21 to 23 allows a pure steel-steel connection, in the z. B. the Lochlaibungspressungen the composite anchor in the wood are no longer crucial. This results in higher power inputs and unlike pure wood-to-wood connections to the benefits of pure steel-steel compounds that are multi-layered.

Of the Composite anchor can with cast bevels of z. B. 2 ° provided be and have radii z. B. be at least 2 mm. The radii of the mandrels relative to the main body of the composite anchor are so executed, that no elevations form and the composite anchor fed into the for his Recording introduced cutouts is applied. The composite anchor may be provided with a zinc coating, where typical run lengths between 5 and 8 μm be.

The geometric dimensions of the composite anchor and the optionally existing holes in it depend on the respective applications. For example can for a wind band connection Wooden construction screws with a diameter of 12 mm are used, which corresponding dimensions of the composite anchor has the consequence. Also becomes the length of the composite anchor according to the to be transmitted Elected forces.

Equally suitable the invention proposal for the connection of stalk-shaped or sheet-shaped Components. Application examples are, for example, fasteners of Wall panels in wooden components.
