Description

"System of interconnected components"

The invention relates to a system of interconnected components, in particular a structural system, with a first component in which a composite anchor provided with thorns is let in, the thorns engaging in the first component, and with at least one further component.

There are a variety of structural designs for a variety of applications. They are used in the construction of buildings as well as in trade fair and stage construction or in the construction of roller coasters. They must be designed to absorb the static and dynamic loads acting on the structure. In addition to the stability of the individual beams and supports, it is particularly important that the forces occurring at the nodes are transmitted reliably by beams or supports connected to one another. Further requirements for structures exist in that they should be simple and inexpensive to manufacture. In many cases, they should also give an aesthetic impression.

BESTATIΘUNGSKOPIE A typical example of the constructions mentioned here is timber construction, in which beams or similar supporting elements are connected to one another to form load-bearing wall, floor and / or roof structures. Various combinations of materials are also used, ie the material wood can be combined with concrete as a filling compound and also with plastic or metal parts. Solid wood, glued laminated timber and other wood-based materials are suitable for the material wood, whereby the solid wood can be designed in particular in the form of round timber, beams, squared timber, planks and crossbeams, which can absorb and transmit relatively high forces compared to the size of their cross-section Location. A cross bar is understood here to be a bar that is formed by dividing one or more tree trunks and rotating the sections about their longitudinal axis and then connecting these parts to form a new bar, with the originally outer parts of the tree or the inner parts then lying inside Arched surfaces forming trees form an opening that extends essentially centrally along the crossbar.

Connections, particularly in the area of the ends of these components, have been developed in a variety of ways and put into practice. For this purpose, only a few known possibilities are given as examples, such as dowels driven in transversely to the longitudinal axis of the bar in the area of tongue and groove connections with bolts and additional screw nails or nail connections with cover brackets or tenons with transverse hardwood dowels or recessed T-steel with rod dowels or tenons, in particular shear tenons and the like. It is known that front-side connections can also be achieved by a so-called beam joint, in which the cross-directional dowel is of a special design Beam sides in the area of their ends are covered on both sides with supporting parts for power transmission.

All these connections have the considerable disadvantage that the systems constructed with them are very complex, both in production - e.g. in the case of butt joints via pins and grooves to be formed in the supporting parts to be connected - and also with regard to the large number of individual parts required, which, moreover, have to be adapted and complicated and frequently installed on-site in uncomfortable positions. In addition, these known connection systems can only be implemented in such a way that they are visible to the outside, unless in the relevant areas, e.g. additional lamination measures would be taken in the area of the tabs or dowel faces.

DE 197 01 458 Cl discloses a timber construction connection for connecting a crossbeam at the end. It has a composite anchor which is embedded in at least one area of an opening which extends over the entire length of the crossbeam, in such a way that its outer end is set back with respect to the end face of the beam. The composite anchor has a rod-shaped core with projecting spikes and a connection option on at least one of the core ends.

With this wood connection, it is possible to create a visually appealing, frontal connection of a cross beam with another component with a minimal number of components with little installation effort. However, with this known wood connection it is not easily possible to build a complete structure. build, as it is primarily designed for frontal use in a cross beam.

The invention has for its object to propose a system of the type mentioned, in which a variety of different connection nodes can be made with few parts, which is easy to install and is also visually appealing.

This object is achieved by a system with the features of claim 1.

Components in the sense of the invention are, in particular, elements of a supporting structure that are subjected to bending, torsion, tension or pressure, such as supports, posts, beams, bars or bars, but also elements to be connected to a support or supporting structure, such as in particular holders for Objects or apparatus to be attached to a carrier.

The system according to the invention has considerable advantages over previously known systems for laterally connecting components:

On the one hand, the forces, the resultants of which run transversely or obliquely to the alignment of the first component, are absorbed by the composite anchor in its interior. The composite anchor is supported in the interior of the first component via its spikes, so that the forces are effectively transferred over a large surface between the composite anchor and the first component, with the result that reinforcing elements are usually on the outer surfaces of the to be connected Components in the area of a node, such as nail plates, can be omitted.

On the other hand, all the parts necessary for the connection of two components can lie within the components, so that they cannot have a negative influence on the visual impression of a structure constructed with the system according to the invention;

Furthermore, a component with a composite anchor according to claim 1 is easy to manufacture, in particular the insertion of the composite anchor in a component can be extremely simple, as will be explained in the following.

Finally, the system according to the invention can be assembled on site and without great effort, since the node connections to be joined are stable and, in particular, no complex fittings to be attached from the outside are necessary.

It is fundamentally irrelevant whether the composite anchor or anchors in the case of elongated components is or are arranged at the end face of one or the ends of the component, in the middle or in an area in between, as long as care is taken during the production of the component is borne that the connection options of the shear connector are accessible from the outside.

In conjunction with the composite anchor known from DE 197 01 458 Cl, a complete supporting structure can thus be constructed in which all the connecting elements are connected to one another inside the NEN components. This offers considerable advantages not only visually, but also statically, as well as in terms of the manufacture of the components and the assembly, compared to previously known supporting structures.

A variety of connection types come into consideration as connection options. In an advantageous embodiment, the composite anchor has a bore with an internal thread as a connection option, which interacts with a connection option with a threaded bolt of a further component. The bore with an internal thread can be designed, for example, as a blind hole, the longitudinal axis of which runs parallel to or in alignment with the longitudinal axis of the further component. With a composite anchor designed in this way, including a corresponding opening in the first component aligned with the bore, it is possible in an extremely simple manner to place a further component laterally on the first component and with the first component, for example via a screw bolt provided on the end face of the component to be fitted to connect, as is easily possible, for example, with an end connection known from DE 197 01 458 Cl. The bore with an internal thread can also run through the composite anchor, so that a component can alternatively be connected to one of the two sides of the first component or two components on both sides of the first component.

Another advantageous connection possibility is that the composite anchor has a bore designed for a bayonet lock, which interacts with a connection possibility designed as a bayonet lock element of a further component. Here is the operation of the connection compared to the operation of the previously discussed bolt connection similar.

This connection system is of course also reversible, in which case the composite anchor in the first component has a bolt, in particular a threaded bolt, as a connection option, which interacts with a bore, in particular with an internal thread, of a connection option for a further component.

In another preferred embodiment, the composite anchor has as a connection option a through-hole extending through the composite anchor, into which a bolt connected to one of the other components engages, the bolt being provided on at least one side with a security against slipping out of the bore. The longitudinal axis of the bore can, like the longitudinal axes of the previously described connection options of the composite anchor, run parallel to the longitudinal axis of an obliquely or transversely connected component or be flush with it, in which case the bolt engaging in the bore is regularly fastened in the region of the end face of the component to be connected will be.

It is also possible for the bore and the bolt to run transversely to the alignment of the component to be connected and at the same time also transversely to the longitudinal axis of the composite anchor in the first component. This can be used, for example, to fasten double beams in pliers-like design to both sides of the first component, which have through holes on the front side, with which the beams are attached to both ends of the bolt and are prevented from slipping out by nuts or similarly acting securing elements placed on their ends. be secured. In this way, the components are even connected to one another in an articulated manner, which can be advantageous depending on the requirements of the system according to the invention.

If the composite anchor is rod-shaped, there is the advantageous possibility of providing connection options running transversely or obliquely to its longitudinal axis in different connection levels. In this way, a connecting node is to be created in which the forces are absorbed over a certain spatial extent of the shear connector, instead of - as is the case in many known connecting nodes - the resultants of the tensile or compressive forces absorbed by a connecting node intersect at one point and the connection node is thereby exposed to a considerably greater load.

In this case, it can also be advantageous if the connection options of adjacent connection planes are pivoted at an angle, in particular at an angle of 90 °, to one another. This makes it possible to connect several further components to the first component in different orientations. This in particular enables a construction with at least two of the further components to be connected to the first component, each of which has the same cross-section, is connected to the first component at the same height and extends in different directions from the first component, with the same What is meant by the same extent of the end connection faces of the further components with respect to the length of the first component. The components connected to the first component can be used, for example, for a mullion / transom construction in a wall construction lie in a horizontal plane while the first component is arranged vertically, it being useful and advantageous, for example, that the at least two components are connected to the first component in alignment with one another.

As already mentioned before, the composite anchors with thorns can be embedded particularly well in cross beams. When manufacturing the crossbar, the two halves of the crossbar are glued together from two parts. Thereafter, such are provided at the points where openings in the crossbar are necessary to access the connection option of the composite anchor. The composite anchor can then be inserted at the intended location in the longitudinal opening of one half of the crossbeam, whereupon the second half is glued to the first half under pressure, with the spikes pressing into or into the inside of the crossbeam intervene blind holes already provided.

The opening running longitudinally in the crossbar does not necessarily have to be in the middle, it can also run parallel to its central longitudinal axis. This can be used so that the composite anchor let into the recess can be laid into the tension or compression plane of the component. You can also change the surface torque of the component by moving the recess from a central position and thereby optimize the bending or torsional rigidity of the component for an assumed load case. This applies not only to crossbeams, but to a large number of other types of components. The components can also be made partially or entirely of concrete. Here, too, the spikes of a composite anchor, provided it is embedded in the component, enable the composite anchor to be anchored very firmly in the component. To ensure that the connection options remain accessible from outside the component, appropriate precautions must be taken so that openings remain in the component at the necessary points when the concrete is poured.

Likewise, the components can consist of different materials, in particular a composite material, in order to achieve sufficient rigidity of the component for the respective application.

As already mentioned above, the possibility of connecting one of the further components can be designed such that it enables an end connection of this component to the first component. This is particularly advantageous insofar as all parts necessary for the connection of the components lie inside the components connected to one another and are therefore not visible from the outside. In a particularly suitable embodiment, the component to be connected has for this purpose a composite anchor which engages in the component with spikes and has connection options on the end face.

For the reasons already mentioned, a composite anchor suitable for the system according to the invention should preferably be rod-shaped and have bores in different planes transversely or obliquely to its longitudinal direction, which in particular can be designed with or without an internal thread and as blind holes or as through bores. It can be advantageous if the holes are neighboring planes are offset from one another at an angle, in particular at an angle of 90 °. Even if an actual connection of another component is not provided for every connection possibility in a structural structure on the component in which the composite anchor is to be used, composite anchors designed in this way can be used universally.

So that bores can be made in the composite anchor, a flat surface is preferably formed on the surface of the composite anchor in the area of the planned bores in relation to its longitudinal axis.

The core of a composite anchor can be designed differently in cross-section, and its shape can be selected, for example, according to the recess available in a component for the composite anchor. The core preferably has a polygonal cross section, in particular with equilateral outer edges. This can result in advantages when positioning the composite anchor in the recess provided for it. The core cross section can be essentially square or else round, in particular circular.

As with the previously known compound anchor acting on the end face, it is also advantageous for the composite anchor with connection options for the lateral connection of workpieces if the spikes are arranged on mutually opposite sides of the compound anchor in substantially parallel planes to one another. This is particularly advantageous for use in components into which the composite anchor is pressed, since in this case the composite anchor is pressed with the NEN can be aligned in the printing direction so that they can be easily pressed into the material of the component.

Another particularly preferred embodiment of the system provides that the at least one further component is connected to the first component by a fastening element which passes through an opening on or in the composite anchor and engages directly in the material of the further component in a positive and / or non-positive manner , The advantage of this configuration is that no composite anchor has to be present in the further component. Rather, the fastener is fixed directly in the other component.

It is preferably also provided here that the fastening element is provided on one side with a security against slipping out of the opening. It is also advantageously provided that the composite anchor is rod-shaped and the opening runs along its longitudinal axis.

The fastening element used in this embodiment variant is preferably a screw. This screw can be designed as a self-tapping or self-drilling screw. It therefore preferably has at least one cutting edge at one end. It can thus be achieved that the screw can be screwed directly into the further component without further preparation, which makes the assembly of the system very easy and therefore economical.

A further embodiment also serves to facilitate assembly, according to which it is provided that at least one of the components in particular the first component, is formed at least in two parts in such a way that the composite anchor let into the component is each approximately half surrounded by a recess in the respective part. The two parts of the component are preferably screwed, nailed, glued or connected in a similar manner.

Further ease of assembly can be achieved in that a through opening is arranged in the component provided with a composite anchor, which adjoins or merges into the recess provided for the composite anchor. The through opening and the recess provided for the composite anchor advantageously run at an angle to one another. This enables a particularly simple tightening of the screw, as described in EP 1 216 332 B1.

The composite anchor for the described system of interconnected components is preferably rod-shaped and has at least one through hole in different planes transverse or oblique to its longitudinal direction and / or along its longitudinal direction.

The invention is explained in more detail below with the aid of drawings, which each show preferred exemplary embodiments of the system according to the invention and its parts. Show it

Fiq. 11 the section through a first component with a total of four integrated composite anchors.

Figures 1 and 2 show part of a mullion / transom construction with a first component designed as mullion 1, to which components designed as transoms 2, 3, 4 are connected. The post 1 is a cross bar with a square cross section, over the entire length of which a central recess 5 extends. A rod-shaped composite anchor 6 is let into this recess.

The bars 2, 3, 4 are also designed as cross bars, but with a rectangular cross section. They are arranged on three of the four sides of the post 1 at the same height. The bars 2, 3, 4 have recesses 7, 8, 9 also extend over their entire length and are located in the respective latch 2, 3 and 4 in different horizontal planes. Thus, the recess 7 of the bolt 2 is in one plane at three-quarters of its cross-section, the recess 8 of the bolt 3 at half the height of its cross-section and the recess 9 of the bolt 4 at one-quarter of its cross-section. A compound anchor 11, 12, 13 is let into each recess 7, 8, 9 at the end of the bar 2, 3, 4 facing the post 1. The composite anchors 11, 12, 13 are rod-shaped and each have a screw bolt running through them

14, the screw head 15 of which is supported on the end face of the composite anchor 11, 12, 13 facing away from the post 1 and engages with its thread in the composite anchor 6 of the post 1 (see FIG. 2).

On each transom 2, 3, 4, an oblique through-opening 16 runs from its upper side to the recess 7, 8, 9, which extends through the recess 7, 8, 9 in the region of the end face of the composite anchor 11, 12, 13 facing away from the post 1 ends. Via these through openings 16 it is possible to use a tool on the screw head

15 of the respective screw bolt 14 act in order to screw the screw bolt 14 into or out of a threaded hole provided in the composite anchor 6 of the post 1.

The possibility shown here of varying the vertical position of the composite anchors 11, 12, 13 by means of a corresponding arrangement of the recesses extending along the crossbeam has a large number of advantages. It is thus possible on the one hand to bring together components such as the bars 2, 3, 4 shown here at the same height, without the bars 2, 3, 4 at the same time transferred forces converge in one level of the composite anchor. In addition, it is possible to arrange the composite anchors 11, 12, 13 vertically so that they each lie in the tension plane of the bars 2, 3, 4. Finally, the area moment of a cross beam can be optimized for a assumed load case by suitable choice of the position of the recess extending through it in the longitudinal direction.

In Figure 2, the interlocking composite anchors of the previously described post / transom construction are shown enlarged. Each of the composite anchors 6, 11, 12, 13 has a rod-shaped core 17 which is provided with spikes 18 which are arranged in parallel planes near two opposite edges of the composite anchors 6, 11, 12, 13.

FIG. 3 shows a composite anchor according to the invention, with which a lateral connection of components to a first component, as described for example with reference to FIGS. 1 and 2, is possible. The composite anchor has a rod-shaped core 22. It is provided with a completely continuous bore 23 along its longitudinal axis a.

Horizontally aligned spikes 24 are provided on the core 22, the spikes 24 being connected to the core 22 in the region of two opposite longitudinal edges 25, 26 and their longitudinal axis lying at an angle of 45 ° to the respectively adjacent outer surfaces of the core 22. The spikes 24 are arranged on opposite sides of the core 22 in two vertical rows parallel to each other. Horizontal through bores 27, 28, 29, 31, 32 running through the core 22 are provided in horizontal planes between the mandrels 24, the through bores 27, 28, 29, 31, 32 in adjacent planes being 90 ° apart are. The Längenach sen b, c, d, e, f of the bores 27, 28, 29, 31, 32 run through the longitudinal outer edges 25, 26, 33, 34 of the composite anchor.

In order to enable the placement of a drill for drilling the core 22 horizontally, the longitudinally extending outer edges 25, 26, 33, 34 of the core 22 are flattened. The latter is particularly advantageous if the core 22 is made from solid material. Another way of manufacturing is to cast the composite anchor. Core elements can be provided in the casting mold, with which it is ensured that through-holes remain along the horizontal drilling axes b, c, d, e, f, which can then optionally be expanded with a drill or made to measure after casting. In this case, it is not necessary to flatten the outer edges.

The horizontal bores 27, 28, 29, 31, 32 can be provided with internal threads for fastening components. However, it is also possible to provide bolts 35, 36, 37, 38, 39 on the composite anchor as connection options, which are inserted into the horizontal bores 27, 28, 29, 31, 32. These bolts 35, 36, 37, 38, 39 can also have a vertical bore in the area of the vertical bore 23 of the composite anchor, through which a securing bolt 41 can be inserted along the longitudinal axis a of the composite anchor, so that the horizontal bolts 35, 36, 37, 38, 39 are secured against slipping out.

Such an arrangement is shown in FIG. 4, for example. The bolts 35, 36, 37, 38, 39, 41 are only shown schematically here. In particular, the securing bolt 41 can have a thread which interacts with a corresponding internal thread in the vertical bore 23 of the composite anchor in order to secure the securing bolt 41 against slipping out of the composite anchor. However, it is also possible that the bolts 35, 36, 37, 38, 39 which penetrate the tie anchor horizontally are formed in one piece with the core 22 of the tie anchor.

Furthermore, each of the horizontally extending bolts 35, 36, 37, 38, 39 can be provided at its ends with connecting, locking or locking elements, so that a connection to another component can be established and secured.

In another alternative, the horizontal bolts 35, 36, 37, 38, 39 can also be part of a composite anchor of a component to be connected, just as they can be an integral part of the component to be connected.

FIGS. 5a to 5c show different cross-sectional shapes for a composite anchor to be used preferably for the system according to the invention. Thus, the core 22 can be circular (FIG. 5a) or square (FIGS. 5b, 5c), the spikes 24 being able to be arranged in two parallel planes parallel to two opposite side faces, or the spikes 24 being arranged in parallel planes. gene, which are pivoted to the opposite side surfaces of the core 22 by 45 °.

FIG. 6 shows a system in section, which - analogous to FIG. 1 - has a first component 1 and a second component 2, which is connected to the first component 1. As explained in the previous figures, a composite anchor 6 with (not designated) mandrels is integrated in the first component 1 in the manner explained above. The composite anchor 6 has an opening (bore) 23 (see FIG. 3) which completely penetrates it along its longitudinal axis a. A screw 40 is inserted through this opening, which screw head has a defined contact surface on the composite anchor 6. The screw 40 has a thread at one end in a known manner. At the end of the thread, i.e. H. At one axial end of the screw 40, cutting edges are arranged which make it possible for the screw 40 to be self-drilling or self-tapping when it is tightened into the material of the second component 2. I.e. no pre-processing of the second component 2 is required before screwing in the screw 40. Rather, the screw 40 can be screwed directly into the second component 2 without preparation.

With this configuration, it is possible to achieve a very stable connection between the two components 1 and 2 in a particularly simple manner: the screw 40 is fixed on or in the screw anchor through its screw head and the opening extending along the longitudinal axis of the connection anchor 6 Composite anchor 6 fixed; the composite anchor 6 is in turn fixed by its spikes in the first component. On the other hand, the screw 40 engages in the material of the second component 2 in a non-positive and positive manner due to its thread. A variant of the solution according to FIG. 6 can be seen in FIG. 7. Here, two first components 1 are fixed to a centrally arranged second component 2. The configuration shown here corresponds otherwise to that according to FIG. 6. Here, two screws 40 are provided, which produce the respective connection between the components 1 and 2.

As can be seen from the embodiment shown in FIG. 8, the first component 1 is fixed here to the second component 2, which is formed here in two parts, by means of two screws 40. For this purpose, two composite anchors 6 are arranged in the first component 1, each of which is penetrated by the screws 40 along their longitudinal axis. With their self-tapping threads, the screws 40 dig into the material of the second component 2 to such an extent that a stable bond is ensured.

Another alternative embodiment is shown in FIG. 9. A total of four first components 1 are connected to the centrally arranged second component 2. The four components 1 are each fixed at (the same) angle relative to the second component 2. In each first component 1, as in the solution according to FIG. 8, two composite anchors 6 are again fixed, which are penetrated by screws 40 which engage with the material of the second component 2 with their self-tapping thread.

How the composite anchors 6 are integrated in the component 1 or arranged therein is shown in the exploded view shown in FIG. 10. The first component 1 consists of here at least two parts la and ib. In each part la, lb, a V-shaped recess 42 and 43 is milled, furthermore - not designated - bores for the mandrels of the composite anchor 6. The cross-sectional shape of the recesses 42 and 43 corresponds to the cross section of the composite anchor 6, so that after Inserting the composite anchor 6 into the recesses 42, 43 and pushing together the two parts la, lb of the component 1 of the composite anchor 6 is fixed in this component. In the left half of FIG. 10 it is indicated that both parts la, lb are joined together by means of an adhesive connection, while the right half of this figure indicates that the two parts la, lb are permanently connected to one another with a number of nails.

A corresponding cross-section through a component 1 similar to FIG. 10 with respective parts 1 a and 1 b can be seen in FIG. 11, the assembled state of the component 1 being shown here. Due to the bores extending deep into the material of the first component 1 for receiving the mandrels (not shown here), the composite anchors 6 are stably fixed in the first component 1.

With the proposed solution, it is possible to display a wide variety of connection options. The proposed system is primarily suitable for connecting - in the broadest sense - wooden sticks. Equally, however, two-dimensional structures can also be connected to one another. Furthermore, with regard to the material, it is also possible to connect parts made of wood, steel, reinforced concrete, masonry and other materials in addition to parts made of wood. The proposed self-tapping screws are basically suitable for all of the materials mentioned. The assembly anchor can be arranged in any direction. It is not necessary for the anchor to be positioned with its longitudinal axis in the direction of the main axis of the component.

With the system described or the composite anchor, assembly can be carried out very quickly and easily in an advantageous manner. The assembly itself can be carried out with the proposed design even under spatially difficult conditions, because only very little space is required for corresponding tools.

Furthermore, there is the possibility of connecting all materials to one another without a threaded sleeve or a similar device having to be arranged in the component in which no composite anchor is arranged. It is usually only provided that the self-tapping or self-drilling screw with a washer or washer is inserted into the longitudinal bore of the anchor and is then self-tapping in the other component.

It is particularly advantageous that a very firm bond is produced between the components to be connected to one another, which meets high demands on the statics.

Finally, it has proven to be advantageous that in the proposal according to the invention, edge distances of the screws to be carried out from the outer edge of the respective wooden part no longer have to be taken into account. This leads to a completely new application. Typical applications in the construction sector are the connections between wooden components. Examples include an impact beam with overlap, the connection of the beam to a solid part, an anchorage of wall panel ends, the connection of a canopy, the connection of a strut in a longitudinal wall to a support or to a threshold, the connection of a support to a threshold , the connection of a diagonal bandage to an eaves or a ridge, the connection of a strut in a gable to a support, the connection of a gable support to a gable frame, and similar applications.

It follows from the foregoing that a large number of further variations in the construction of a composite anchor which can be used for the system of components, as well as a large number of different supporting structures, are possible without thereby departing from the scope of the invention.
