Description

[0001] The present invention relates to a connecting element for beams, preferably for wooden beams.

[0002] The use of wood as a building material has been known since ancient times. Houses, dwellings, and other buildings have been constructed with wood as a primary or load-bearing material, i.e., the material that provides structural stability, since time immemorial. While availability and stability were originally the primary reasons for this, over time, design and processing options, as well as aesthetics, have been added. Today, sustainability also plays an important role in the use of wood as a building material.

[0003] Nowadays, metal fasteners are commonly used to hold several wooden construction elements together. In the simplest case, these can be metal nails, screws, and sometimes nuts. These fasteners also include so-called building fittings, or fittings for short, such as wood connectors, as well as shoes, anchors, or feet for connecting wooden elements to the substructure, for example, as a concrete screed or the like. Wood connectors include, in particular, angle connectors, strut connectors, and flat connectors, which are usually used to connect two wooden beams at right angles or in a straight line. Beam shoes and T-beam supports are also used to connect two wooden beams at right angles.

[0004] It is also common practice today to use similarly designed building elements in order to keep the number of different types of building elements to a minimum. This can simplify design, assembly, construction and storage. If, instead of simple beams and the like, identically designed assemblies are used multiple times, this can be referred to as modular construction. Such an assembly can, for example, consist of several wooden building elements that are held together as an assembly by connecting elements. This means that these parts of the building can be manufactured in advance as assemblies and then assembled on site, i.e. at the location of the building or structure, to form the building or structure.

[0005] The structures and buildings that are currently constructed from wood or with wood as a main or load-bearing building material typically include small buildings such as single-family homes, outbuildings such as sheds, garages, and carports, as well as smaller commercial buildings. Smaller residential buildings also include so-called tiny houses, in which the use of materials and living space are already kept to a minimum for the sake of sustainability, so that the aspect of sustainability can be further supported by the use of wood as a building material. In any case, such buildings can be assembled from modules. Such modularly constructed buildings, and in particular tiny houses and the like, are usually small and, in particular, single-story buildings, which are usually constructed and used at ground level.

[0006] However, the disadvantage of such modules so far is that they are comparatively large and heavy, which reduces the assembly steps at the building site. This typically requires a crane to unload the modules from the transport vehicle and assemble them into the building. This is especially true for multi-story buildings.

[0007] This is due to the fact that, to date, attempts have been made to manufacture the modules centrally as far as possible, with regard to assembly steps, and then transport them to the building site in such a way that on-site effort can be minimized. This also leads to comparatively complex logistics in terms of transport, as well as increased energy consumption and thus increased CO2 emissions, which contradicts the idea of ​​sustainability, especially in tiny houses.

[0008] Another disadvantage is that, despite the modularity that promises certain flexible construction and design options, existing modular buildings are limited to the predefined modules. Thus, modularity tends to limit design options when planning the building. This also applies to subsequent expansions such as the construction of an annex, which can only be achieved with comparatively high costs, if at all.

[0009] Another disadvantage is that a foundation slab is usually required in the subsoil, i.e. it must be created beforehand, on which the building with its modules is erected.

[0010] Another disadvantage is that with modular buildings such as tiny houses and the like, due to the high degree of completion of the modules ex works, there are comparatively few opportunities for the builder to lend a hand and reduce construction costs through their own work.

[0011] One object of the present invention is to improve or expand the possibilities for constructing a building with a beam construction. This should be made possible especially for wooden beams. In particular, the flexibility and design options should be improved or expanded. In particular, a modular construction method with the simplest possible building elements or assemblies that can be moved or carried by people should be enabled. In particular, the building owner's options for providing their own work should be increased. In any case, this should be possible in the simplest, most compact, most cost-effective and / or most sustainable way possible. At the very least, an alternative to the previously known options should be created.

[0012] The object is achieved according to the invention by a connecting element for beams, by a building, and by a building structure having the features of the independent claims. Advantageous further developments are described in the subclaims.

[0013] The present invention therefore relates to a connecting element for beams, preferably for wooden beams. The connecting element can also be referred to as a fitting, a connector or a wooden connector. The connecting element preferably comprises metal or is made of metal, although a corresponding plastic, possibly fiber-reinforced, can also be used as a material alone or in addition to metal, i.e. in combination with one another. In the case of a metallic design, the individual elements of the connecting element can be manufactured separately and then joined to one another in one piece, in particular by welding. Alternatively, the individual elements of the connecting element can also be manufactured integrally, i.e. in one piece or from a single piece, by primary shaping and / or by forming. This can also be done partially in each case. The beam to which the connecting element is to be connected during use can also be made of wood orwood, but alternatively or additionally also contain or consist of other comparably stable materials.

[0014] The connecting element has a base element with a vertical stop element and with a first horizontal contact element, which are aligned at an angle, preferably at right angles, to one another and are fixedly connected to one another, preferably welded or formed integrally, wherein the vertical stop element is designed to receive an end face of a vertical beam, preferably a vertical wooden beam, in a flat manner along the vertical axis by means of a stop surface, and wherein the first horizontal contact element is designed to receive the first side face of the vertical beam, which is immediately adjacent to the end face and aligned at an angle, preferably at right angles, to the end face, in a flat manner along the transverse axis by means of a contact surface, wherein the base element is designed to be fixedly connected to the vertical beam, preferably by means of at least one screw connection.

[0015] "Angular" means that the corresponding surfaces form an angle between them that is less than 180°, so that the two surfaces do not adjoin one another in a straight line, but rather one surface is inclined to the other by the adjacent angle of the jointly included angle. The lower value of the included angle is limited by the fact that there is still a sufficiently wide space between the two surfaces to accommodate the corresponding beam. The included angle is preferably at least 60°. "Right-angled" means an included angle and a adjacent angle of 90°.

[0016] The axis designations used are to be understood in Cartesian coordinates, so that the axes are aligned at right angles to each other. If the elements and surfaces extend primarily at right angles to each other, then the elements or surfaces are also aligned exactly according to the named axis in Cartesian coordinates. If, however, the elements and surfaces extend only at an angle but not at right angles to each other, the named axes are to be understood in such a way that the elements and surfaces extend essentially along the corresponding axis, but to an inverse extent along the corresponding other axis.

[0017] The previously described features of the base element make it possible to align the base element on two sides of the vertical beam, which is used or mounted at least substantially and preferably precisely aligned along the vertical axis, and to fasten it firmly to the vertical beam. For this purpose, the base element can be placed from above along the vertical axis onto the upper end face of the already fixedly mounted beam, whereby this movement can be terminated in a form-fitting manner by the stop surface of the vertical stop element striking the upper end face of the vertical beam. The base element can then be displaced horizontally in order to simultaneously bear flatly with its first horizontal contact surface against the first side face of the vertical beam, which can improve or complete the positioning of the base element relative to the vertical beam.This can lead to simple and reliable positioning, which can then be secured in place, for example by screwing.

[0018] The first horizontal contact element is further configured to receive the end face of a first horizontal beam, preferably a first horizontal wooden beam, facing away from the contact surface along the transverse axis in a planar manner along the transverse axis, wherein the base element further comprises a first horizontal wing which, facing away from the contact surface of the first horizontal contact element, is oriented at an angle, preferably at a right angle, projecting from the first horizontal contact element along the transverse axis and is fixedly connected to the first horizontal contact element, preferably welded or formed integrally, and wherein the first horizontal wing is configured to receive, by means of a contact surface, a side face of the first horizontal beam, preferably a first horizontal wooden beam, which side face is oriented at an angle, preferably at a right angle, to the end face, along the longitudinal axis in a planar manner,The base element is further configured to be fixedly connected, preferably by means of at least one screw connection, to the first horizontal beam. The wing can be fixedly attached, in particular, to the edge, i.e., to a vertically extending edge of the first horizontal support element, in order to accommodate the first horizontal beam laterally with as full a cross-section as possible, which can improve stability.

[0019] In any case, a similarly designed receptacle for a first horizontal beam can be created in order to position and fasten it to the base element in two directions arranged at an angle to one another in a manner similar to that described above with regard to the vertical beam, which can also preferably be done by means of a screw connection at this point.

[0020] The present invention is based on the finding that previously known connecting elements or wood connectors of this type are arranged laterally of the beams to be connected. This can lead to inaccuracies in positioning. It can also limit the load-bearing capacity or stability of the connection between the two beams.

[0021] According to the invention, a connecting element for beams is therefore provided, which has at least one base element or consists of at least one base element. The base element improves the positioning accuracy of the beams relative to one another and / or the stability of the connection between the two beams to one another in that, on the one hand, each of the two beams rests against the base element both with its end face and with a surface lateral to the end face. On the other hand, the contact surface of the first horizontal contact element lies between the side surface of the vertical beam and the end face of the first horizontal beam, which improves both the positioning accuracy and the stability. In particular, the vertical stop element of the base element can transmit the weight of the first horizontal beam securely and evenly to the end face of the vertical beam.

[0022] The connecting element according to the invention, or its base element, can be used particularly usefully in the construction of buildings, especially those made of wood or using wooden beams, since the connecting element can be used at all connection points between a vertical beam and a horizontal beam as described above. This eliminates the need for other connecting elements or wood connectors.

[0023] Beams can also be directly connected to one another in this way. If the beams are sufficiently short or lightweight, they can be handled by people, eliminating the need for a crane to erect the building. This can reduce construction costs and increase the flexibility of the project. This can also increase the client's ability to provide their own labor.

[0024] Furthermore, the connecting element according to the invention or its base element can be flexibly deployed or used within the beam structure of the building, which can improve or expand the flexibility and design options. This applies in particular to a modular construction, in which the connecting element according to the invention or its base element can be used multiple times as a modular element and, in particular, flexibly, as already mentioned.

[0025] According to one aspect of the invention, the contact surface of the first horizontal contact element has at least one through-opening along the transverse axis, preferably a pair of through-openings offset from one another along the vertical axis, and / or the contact surface of the first horizontal wing has at least one through-opening along the longitudinal axis, preferably a pair of through-openings offset from one another along the vertical axis.

[0026] A fixed connection to the corresponding beam can be established through the through-hole, which is one possible option for such a connection. This can be achieved, in particular, by means of a corresponding screw that penetrates or cuts into the material of the beam, or by means of a screw-nut connection through a corresponding through-hole or bore through the beam. The through-hole of the base element can also have a thread for screwing in the screw. This allows for various simple and cost-effective yet stable options for a fixed connection.

[0027] By arranging the through openings in duplicate or in pairs, the stability of the connection can be increased and, in particular, rotation around the axis of only one connection can be prevented.

[0028] According to a further aspect of the invention, the vertical stop element protrudes beyond the first horizontal wing along its longitudinal axis. Accordingly, the first horizontal wing is recessed along its longitudinal axis, so that screw heads located opposite the contact surface of the first horizontal wing can be accommodated within the contour of the vertical stop element. Thus, a flat cladding or the like can be applied from the outside, resting against both the vertical beam and the first horizontal beam, without the screw heads interfering.

[0029] According to a further aspect of the invention, the base element further comprises a second horizontal contact element which is aligned at an angle, preferably at a right angle, to both the vertical stop element and the first horizontal contact element and is fixedly connected, preferably welded or integrally formed, wherein the second horizontal contact element is designed to receive, by means of a contact surface, the second side surface of the vertical beam, which is directly adjacent to the end face and aligned at an angle, preferably at a right angle, to the end face and to the first side surface, in a flat manner along the longitudinal axis.

[0030] In this way, the corresponding aspects and advantages described above can be transferred to a further second horizontal support surface of a second horizontal support element and also used and applied on or at the second side of the vertical beam. Two horizontal support surfaces on the side of the base element can further improve its positioning as well as stability and support at the upper end of the vertical beam.

[0031] According to a further aspect of the invention, the contact surface of the second horizontal contact element has at least one through-hole along the longitudinal axis, preferably a pair of through-holes offset from one another along the vertical axis. Thus, a connection can also be made at this point using screws or the like, as described above.

[0032] According to a further aspect of the invention, the through-opening of the contact surface of the second horizontal contact element is offset along the vertical axis relative to the through-opening of the contact surface of the first horizontal contact element. This can prevent the screws or the like from touching or blocking each other when inserted sufficiently deep into the material of the vertical beam.

[0033] According to a further aspect of the invention, the second horizontal contact element is further designed to receive the end face of a second horizontal beam, preferably a second horizontal wooden beam, facing away from the contact surface along the longitudinal axis in a flat manner along the longitudinal axis, wherein the base element further comprises a second horizontal wing which is oriented away from the contact surface of the second horizontal contact element along the longitudinal axis at an angle, preferably at a right angle, projecting from the second horizontal contact element and fixedly connected to the second horizontal contact element, preferably welded or formed integrally, wherein the second horizontal wing is designed to engage, by means of a contact surface, a side surface of the second horizontal beam, preferably a second horizontal wooden beam, which side surface is oriented at an angle, preferably at a right angle, to the end face,along the transverse axis in a flat manner, wherein the base element is further designed to be fixedly connected to the second horizontal beam, preferably by means of at least one screw connection.

[0034] In this way, the corresponding aspects and advantages described above can be transferred to the second horizontal support element and to a second horizontal wing, and used and applied to attach a second horizontal beam. Thus, the beam construction can be expanded according to the invention to include a second horizontal beam.

[0035] According to a further aspect of the invention, the vertical stop element extends beyond the second horizontal wing along the transverse axis. This allows the corresponding properties and advantages described above to be implemented and utilized at this location as well.

[0036] According to a further aspect of the invention, the contact surface of the second horizontal wing has at least one through-hole along the transverse axis, preferably a pair of through-holes offset from one another along the vertical axis. Thus, a connection can also be made at this point using screws or the like, as described above.

[0037] According to a further aspect of the invention, the connecting element further comprises a first corner connector with a wing contact element and with a wing, which are aligned at an angle, preferably at right angles, to one another and are fixedly connected to one another, preferably welded or formed integrally, wherein the wing contact element is designed to bear flatly against the first horizontal wing by means of a contact surface along the longitudinal axis of the contact surface of the first horizontal wing, wherein the wing contact element is further designed to be fixedly connected, preferably by means of at least one screw connection, to the first horizontal wing of the base element, wherein the wing is designed to extend the contact surface of the first horizontal contact element of the base element along the longitudinal axis by means of a contact surface.

[0038] In this way, the connecting element according to the invention can be expanded by adding a first corner connector to the base element, providing additional mounting options, such as, in particular, the attachment of a third horizontal beam, as will be described in more detail below. The previously described advantages and properties can be transferred accordingly to the first corner connector.

[0039] According to a further aspect of the invention, the contact surface of the wing contact element of the first corner connector has at least one through-opening along the longitudinal axis, preferably a pair of through-openings offset from one another along the vertical axis, wherein the through-opening of the contact surface of the wing contact element of the first corner connector is arranged congruently with the through-opening of the contact surface of the second horizontal contact element. As a result, the corresponding properties and advantages as described above can also be applied and utilized for the first corner connector.

[0040] According to a further aspect of the invention, the wing of the first corner connector is further configured to receive, by means of the contact surface, a side surface of a third horizontal beam, preferably a third horizontal wooden beam, which is oriented at an angle, preferably at right angles, to a front side, in a flat, abutting manner along the transverse axis. This also allows a third horizontal beam to be positioned and secured relative to the vertical beam and relative to the two other horizontal beams using the connecting element according to the invention, as described above.

[0041] According to a further aspect of the invention, the contact surface of the wing of the first corner connector has at least one through-opening along the transverse axis, preferably a pair of through-openings offset from one another along the vertical axis. This allows the corresponding properties and advantages described above to be applied and utilized in the first corner connector as well.

[0042] According to a further aspect of the invention, the connecting element according to the invention further comprises a second corner connector with a wing contact element and with a wing, which are aligned at an angle, preferably at right angles, to one another and are fixedly connected to one another, preferably welded or formed integrally, wherein the wing contact element is designed to bear flatly against the second horizontal wing by means of a contact surface along the transverse axis facing away from the contact surface of the second horizontal wing, wherein the wing contact element is further designed to be fixedly connected, preferably by means of at least one screw connection, to the second horizontal wing of the base element, wherein the wing is designed to extend the contact surface of the second horizontal contact element of the base element along the transverse axis by means of a contact surface.

[0043] In this way, a second corner connector, preferably identical or mirror-symmetrical to the first corner connector, can be used or supplemented in order to transfer the corresponding properties and advantages already described to this extension of the basic element.

[0044] The present invention also relates to a building or a building structure with at least one connecting element as described above. A building is understood to be a complete or finished and usable building, and a building structure is understood to be its load-bearing elements or its load-bearing structure. Thus, a connecting element according to the invention can be used in a building or its building structure as described above, and its properties and advantages can be realized therein.

[0045] An embodiment and further advantages of the invention are illustrated and explained in more detail below in conjunction with the following figures. Fig. 1 a perspective schematic representation of a basic element of a connecting element according to the invention, viewed obliquely from below; Fig. 2 the representation of the Fig. 1 from the back diagonally from below; Fig. 3 the representation of the Fig. 1 directly from above; Fig. 4 a perspective partially exploded view of the use of the basic element of the connecting element according to the invention with one vertical bar and two horizontal bars, viewed obliquely from below; Fig. 5 the representation of the Fig. 4 with connected vertical beam; Fig. 6 a perspective view of the arrangement of the Fig. 5 with a third horizontal bar diagonally from above; and Fig. 7 a perspective view of a building structure of a building using connecting elements according to the invention.

[0046] The above figures are viewed in Cartesian coordinates. There is a longitudinal axis X, which can also be referred to as depth X or length X. Perpendicular to the longitudinal axis X extends a transverse axis Y, which can also be referred to as width Y. Perpendicular to both the longitudinal axis X and the transverse axis Y extends a vertical axis Z, which can also be referred to as height Z and corresponds to the direction of gravity or gravitational force. The longitudinal axis X and the transverse axis Y together form the horizontal X, Y, which can also be referred to as the horizontal plane X, Y.

[0047] Fig. 1 shows a perspective schematic representation of a base element 1 of a connecting element 1-3 according to the invention, viewed obliquely from below. Fig. 2 shows the representation of the Fig. 1 from the back diagonally from below. Fig. 3 shows the representation of the Fig. 1 directly from above. Fig. 4 shows a perspective partially exploded view of the use of the base element 1 of the connecting element 1-3 according to the invention with a vertical bar 4 and two horizontal bars 5, 6 from obliquely below. Fig. 5 shows the representation of the Fig. 4 with connected vertical bar 4. Fig. Figure 6 shows a perspective view of the arrangement of the Fig. 5 with a third horizontal bar 7 diagonally from above.

[0048] The already mentioned connecting element 1-3 according to the invention consists in the simplest case only of the basic element 1, see Fig. 1 to 3. The connecting element 1-3 can also be referred to as fitting 1-3.

[0049] The base element 1 has a vertical stop element 10, which is designed as a square surface, which is aligned in the horizontal X, Y during use. The vertical stop element 10 can also be referred to as a vertical stop plate 10 or simply as a vertical stop 10. The vertical stop element 10 has a corresponding square stop surface 10a, which is aligned along the vertical axis Z, ie its surface normal points along the vertical axis Z. In the considered embodiment of the Fig. 1 to 3 or in the application example considered the Fig. 4 to 6, the stop surface 10a points downwards along the vertical axis Z.

[0050] The base element 1 further comprises a first horizontal contact element 11, which is aligned at right angles to the vertical stop element 10. The first horizontal contact element 11 can also be referred to as the first horizontal stop 11. The surface of the first horizontal contact element 11 facing the vertical stop element 10 represents a contact surface 11a of the first horizontal contact element 11, which has a pair of through openings 11b, which are located directly above one another along the vertical axis Z and are spaced as evenly as possible from the two edges (not designated) of the first horizontal contact element 11 both along the vertical axis Z and along the longitudinal axis X.

[0051] The base element 1 further comprises a second horizontal contact element 12 as a second horizontal stop 12, which is also aligned at right angles to the vertical stop element 10 and at right angles to the first horizontal contact element 11. The second horizontal contact element 12 can also be referred to as a second horizontal stop 12. The surface of the second horizontal contact element 12 facing the vertical stop element 10 represents a contact surface 12a of the second horizontal contact element 12, which also has a pair of through openings 12b, which are spaced as evenly as possible from the two edges (not designated) of the second horizontal contact element 12 along the vertical axis Z, directly one above the other, and both along the vertical axis Z and along the transverse axis Y.The two through-openings 11b of the first horizontal support element 11 are offset along the vertical axis Z relative to the two through-openings 12b of the second horizontal support element 12. The two horizontal support elements 11, 12 and the vertical stop element 10 are each welded to one another at an edge (not designated).

[0052] The base element 1 also has a first horizontal wing 13, which is oriented away from the contact surface 11a of the first horizontal contact element 11 and extends perpendicularly from the first horizontal contact element 11 along the transverse axis Y. The first horizontal wing 13 is oriented vertically, so to speak, and is fixedly arranged by welding along the longitudinal axis X at the edge of the first horizontal contact element 11 that faces away from the second horizontal contact element 12. The first horizontal wing 13 can also be referred to as the first horizontal connector 13.The side of the first horizontal wing 13 which faces the second horizontal contact element 12 along the longitudinal axis X represents the contact surface 13a of the first horizontal wing 13, which also has a pair of through openings 13b which are spaced as evenly as possible from the two edges (not designated) of the first horizontal wing 13 along the vertical axis Z directly one above the other and both along the vertical axis Z and along the transverse axis Y.

[0053] Analogous to the first horizontal wing 13, the base element 1 has a second horizontal wing 14, which is oriented away from the contact surface 12a of the second horizontal contact element 12 along the longitudinal axis X and projects perpendicularly from the second horizontal contact element 12. The second horizontal wing 14 is also oriented upright and is fixedly arranged by welding along the transverse axis Y at the edge of the second horizontal contact element 12 that faces away from the first horizontal contact element 11. The second horizontal wing 14 can also be referred to as a second horizontal connector 14.The side of the second horizontal wing 14 which faces the first horizontal contact element 11 along the transverse axis Y represents the contact surface 14a of the second horizontal wing 14, which also has a pair of through openings 14b which are directly above one another along the vertical axis Z and are spaced as evenly as possible from the two edges (not labeled) of the second horizontal wing 14 both along the vertical axis Z and along the longitudinal axis X. The two wings 13, 14 of the base element 1 represent identical parts, ie they are identically designed, which simplifies production.

[0054] The base element 1 of the connecting element 1-3 according to the invention can now be used to connect several beams 4-6 as wooden beams 4-6 at right angles to one another by attaching a vertical beam 4 extending upwards along the vertical axis Z to a substrate (not shown), which can be done by means of another base element 1 of the connecting element 1-3 according to the invention. The vertical beam 4 ends along the vertical axis Z at its upper end with a square end face 40, which corresponds exactly to the contour of the stop surface 10a of the vertical stop element 10 of the base element 1.From there, a first side surface 43 and a second side surface 44 extend away along the vertical axis Z, which together end at a support edge 45, which represents a one-sided recess of the outer contour of the vertical beam 4 both along the transverse axis Y and the longitudinal axis X. In the further course, the vertical beam 4 extends with a square cross-section along the vertical axis Z, which extends both along the transverse axis Y beyond the extension of the vertical stop element 10 and the thickness or strength of the first horizontal contact element 11 and along the longitudinal axis X beyond the extension of the vertical stop element 10 and the thickness or strength of the second horizontal contact element 12.The two side surfaces 43, 44 each have a pair of through openings 41, 42, which are each arranged along the vertical axis Z directly above one another and corresponding to the through openings 11a, 12a of the two horizontal contact elements 11, 12.

[0055] To assemble the base element 10 of the connecting element 1-3 according to the invention, a person can now align the base element 10 so that the two horizontal contact elements 11, 12 face the two side surfaces 43, 44 of the vertical beam 4. The base element 10 can then be placed along the vertical axis Z from above, with the stop surface 10a of the vertical stop element 10 facing forward, onto the end face 40 of the vertical beam 4. If the horizontal alignment has not already been achieved, the person can now push the base element 10 with its two horizontal contact elements 11, 12 toward the two side surfaces 43, 44 of the vertical beam 4.In this arrangement, the base element 10 can be fixedly connected to the corresponding pairs of through-openings 11b, 12b of the two horizontal contact elements 11, 12 of the base element 1 by means of four screw connections (not shown) through the now congruently aligned pairs of through-openings 41, 42 of the two side surfaces 43, 44 of the vertical beam 4.

[0056] A first horizontal beam 5 can now be mounted on the first horizontal wing 13, which extends along the vertical axis Z and along the transverse axis Y. The first horizontal beam 5 in the form of a first horizontal wooden beam 5 ends along the transverse axis Y with a rectangular end face 50, to which a wing receptacle 52 aligned along the longitudinal axis X in the form of a recess relative to the remaining rectangular contour of the first horizontal beam 5 adjoins at right angles. The surface set back along the longitudinal axis X represents a side surface 53 of the first horizontal beam 5. The outer side (not designated) of the first horizontal beam 5 opposite the longitudinal axis X merges into the end face 50 with a contact surface 54 inclined at 45° and with a further inclination of 45°.

[0057] For assembly, the first horizontal beam 5 is now raised to the height of the base element 1 as previously described and then pushed past the first horizontal wing 13 along the transverse axis Y with its end face 50 of the contact surface 11a facing away from the transverse axis Y against the first horizontal contact element 11. In doing so, a lower edge (not designated) of the first horizontal beam 5 slides into a gap formed along the vertical axis Z between the support edge 45 of the vertical beam 4 and the lower edge (not designated). As a result, the first horizontal beam 5 rests directly on the support edge 45 of the vertical beam 4.Then, the first horizontal beam 5 is placed along the longitudinal axis X with its side surface 53 against the contact surface 13a of the first horizontal contact element 11 and is fixedly fastened there in this position by means of screw connections through the pair of through openings 13b of the first horizontal wing 13.

[0058] Analogously, a second horizontal beam 6 can then be attached to the second wing 14 of the base element 1. The second horizontal beam 6 is also designed as a second horizontal wooden beam 6 and ends along the longitudinal axis X with a rectangular end face 60, which is adjoined at right angles by a wing receptacle 62 aligned along the transverse axis Y in the form of a recess compared to the remaining rectangular contour of the second horizontal beam 6. The surface set back along the transverse axis Y represents a side surface 63 of the second horizontal beam 6. The outer side (not designated) of the second horizontal beam 6 opposite the longitudinal axis X merges into the end face 60 with a contact surface 64 inclined at 45° and with a further inclination of 45°. In the assembled state, the two contact surfaces 54, 64 of the two horizontal beams 5, 6 rest against one another.

[0059] In order to expand the assembly and connection options of the connecting element 1-3 according to the invention compared to the two previously described horizontal beams 4, 5, the connecting element 1-3 according to the invention comprises, in addition to the previously described basic element 1, a first corner connector 2 and a second corner connector 3, which are of identical design.

[0060] The first corner connector 2 has a wing contact element 20, which is oriented vertically and extends parallel to the first horizontal wing 13 of the base element 1 along the transverse axis Y. In use, the wing contact element 20 rests with a contact surface 20a flat against the side of the first horizontal wing 13 of the base element 1 facing away from its contact surface 13a. The wing contact element 20 of the first corner connector 2 also has a pair of through-openings 20b on the side of the contact surface 20a, which are arranged corresponding to the through-openings 13b of the first horizontal wing 13 of the base element 1.Thus, the two screw connections can each connect the first corner connector 2 and the first horizontal beam 4 to the first horizontal wing 13 of the base element 1 in a fixed manner through the corresponding through-opening 13b of the first horizontal wing 13 of the base element 1 and through the overlying through-opening 20b of the wing contact element 20 of the first corner connector 2.

[0061] The first corner connector 2 further comprises a wing 21, which can also be referred to as a horizontal connector 21. The wing 21 is fixedly arranged at a right angle with one edge (not designated) to the corresponding edge (not designated) of the wing contact element 20 of the first corner connector 2 and extends along the longitudinal axis X such that a contact surface 21a of the wing 21 of the first corner connector 2 extends the contact surface 11a of the first horizontal contact element 11 of the base element 1 in a flush manner. The contact surface 21a of the wing 21 of the first corner connector 2 also comprises a pair of through-openings 21b, which are arranged directly above one another along the vertical axis Z and are spaced as evenly as possible from the two edges (not designated) of the wing 21 along both the vertical axis Z and the longitudinal axis X.

[0062] In this way, a third horizontal beam 7 in the form of a third horizontal wooden beam 7 with a rectangular end face 70 can be attached along the longitudinal axis X to that outer side (not labeled) of the vertical beam 4 which is opposite the second side surface 44. The third horizontal beam 7 has a recess along the transverse axis Y, which forms a wing receptacle 72 of the third horizontal beam 7, with the side surface 73 of which the third horizontal beam 7 can be attached to the first corner connectors 2 along the transverse axis Y. In this position, the third horizontal beam 7 can now be held stationary there by screwing through the through-openings 21b of the contact surface 21a of the wing 21 of the first corner connector 2.

[0063] Analogously, a second corner connector 3 can be fastened as an identically designed component with a wing contact element 30 with a contact surface 30a with a pair of through openings 30b and with a wing 31 or with a horizontal connector 31 with a contact surface 31a with a pair of through openings 31b to the second horizontal wing 14 of the base element 1 in order to hold a fourth horizontal beam (not shown) stationary there.
