Abstract
Description
[0001] Title: LOAD TRANSFER ARRANGEMENT FOR A WOODEN COMPONENT
[0002] Technical background
[0003] The invention relates to a load transfer arrangement for a wooden or wood-based material component, with a lifting fitting embedded in a wooden component.
[0004] The object of the invention is to create a load transfer arrangement for absorbing large forces, in which shear stress on the fastening screws is avoided as much as possible.
[0005] The invention is particularly suitable for the repeated joining and unjoining of heavy wooden parts. For example, the invention is suitable for the repeated lifting of heavy wooden parts, but also for the repeated connection of loads that do not result from a lifting process, e.g., in the case of components joined together with the aid of the load transfer arrangement.
[0006] Summary of Revelation
[0007] One aspect of the invention relates to a load transfer arrangement for a wooden or wood-based material component, comprising a fitting embedded in a wooden component, wherein the fitting is plate-shaped with a first diameter, a thickness, and an outer surface with a central axis, and is embedded in a congruent recess in the wooden component, which has a second diameter corresponding to the first diameter, a depth preferably at least corresponding to the thickness, and an inner surface, wherein the fitting has a number, in particular a plurality, of screw holes extending in the thickness direction, through each of which a fastening screw screwed into the wooden component extends, wherein the fastening screws are arranged substantially parallel to each other and substantially parallel to the central axis of the fitting, and wherein the fitting has a fastening means for connecting to a connecting device.by which a vertical force acting parallel to the central axis of the fitting and a horizontal force acting perpendicular to it can be introduced into the fitting, wherein the vertical force can be introduced into the wooden component via the fastening screws and the horizontal force can be introduced completely or to a large extent from the outer surface of the fitting via the inner surface of the recess into the wooden component.
[0008] Due to the arrangement of the fastening screws parallel to the central axis of the fitting and the precisely fitting recess, and thus in the direction of or parallel to the object to be received.
[0009] December 18, 2025 1 / 19 Due to the vertical force on the one hand, and the perpendicular orientation of the outer surface of the fitting and the inner surface of the recess in the wooden component, and thus in the direction of or parallel to the horizontal force to be absorbed, on the other hand, the horizontal force is absorbed entirely or almost exclusively by the surface pressure between parts of the outer surface of the fitting and the inner surface of the recess, while the vertical force is absorbed exclusively by the fastening screws. This allows the fastening screws, as well as the size and diameter of the outer and inner surfaces, to be optimally adapted to the expected load components, and ensures that additional shear stress on the fastening screws is completely or almost completely avoided.A slight eccentricity of the vertical force in relation to the fastening screws is compensated for by a corresponding uneven tensile stress on the fastening screws.
[0010] By fastening the fitting in the recess and to the wooden component using the fastening screws, and by additionally providing a fastener for connection to a connecting device, the invention combines the advantages of timber construction with those of metal construction, particularly when the fastener includes, for example, an opening with an internal thread, especially a metric thread. In this way, the fitting can be easily and permanently connected to the wooden component using the fastening screws, which are typically wood screws. The fastener, through which horizontal and vertical forces are introduced into the fitting, can be used for repeatedly connecting and disconnecting a connecting device to and from the fitting.For example, a connecting device in the form of a timber connector can be repeatedly attached to and detached from the fitting, and thus from the permanently connected timber component, using a fastening element such as a bolt with a metric external thread, without weakening the permanent timber connection between the fitting and the timber component. This contributes to the sustainable reusability and reassembly of the associated timber structures.
[0011] A further aspect of the invention relates to a load transfer arrangement for a wooden or wood-based material component, comprising a lifting fitting embedded in a wooden component to be lifted, which is cylindrically plate-shaped with a first diameter, a thickness and a cylindrical outer surface with a cylinder axis and is embedded in a cylindrical recess in the wooden component, which has a second diameter corresponding to the first diameter, a depth preferably at least corresponding to the thickness of the lifting fitting and a cylindrical inner surface, wherein the lifting fitting is equipped with a number, in particular a plurality, of thickness-directed
[0012] December 18, 2025 2 / 19 is provided with screw holes through which a fastening screw extends into the wooden component, wherein the fastening screws are arranged parallel to each other and in the direction of the cylinder axis of the lifting fitting, wherein the lifting fitting has a fastening means for connecting to a lifting device, through which a vertical force acting in the direction of the cylinder axis of the lifting fitting and a horizontal force acting transversely thereto can be introduced into the lifting fitting, wherein the vertical force can be introduced into the wooden component through the fastening screws and the horizontal force can be introduced completely or to a large extent from the outer surface of the lifting fitting via the inner surface of the recess into the wooden component.
[0013] Within the scope of this disclosure, the terms horizontal force and vertical force can each refer to the local coordinate system of the respective fitting. For example, if several fittings are arranged perpendicular to each other, the direction of the horizontal force of one fitting can correspond to the direction of the vertical force of another fitting, and vice versa.
[0014] Due to the arrangement of the fastening screws in the direction of the cylinder axis of the lifting fitting and the precisely fitting recess, and thus in the direction of the vertical force to be absorbed, on the one hand, and due to the perpendicular orientation of the outer surface of the lifting fitting and the inner surface of the recess in the wooden component, and thus in the direction of the horizontal force to be absorbed, on the other hand, in the case of a load, the horizontal force is absorbed entirely or almost exclusively by the surface pressure between parts of the outer surface of the lifting fitting and the inner surface of the recess, while the vertical force is absorbed exclusively by the fastening screws.This allows both the fastening screws and the size and diameter of the outer and inner surfaces to be optimally adapted to the expected load components, ensuring that additional shear stress on the fastening screws is completely or almost completely avoided. A slight eccentricity of the vertical force with respect to the fastening screws is compensated for by a corresponding uneven tensile stress on the fastening screws.
[0015] The fitting may contain metal. It may be made of or consist of stainless steel, steel, aluminum, titanium, non-ferrous metals, or alloys thereof. The material may be chosen to achieve specific properties, such as corrosion resistance, non-magnetic properties, particularly low weight, etc.
[0016] An essentially parallel arrangement of the fastening screws to each other and to the central axis of the fitting can be a parallel arrangement ±30°, or ±20°, or ±15°, ± or 10°,
[0017] December 18, 2025 3 / 19 or ± 7.5°, or ± 5°, or ± 3°, or ± 2°, or ± 1°, or ± 0.5° mean.
[0018] The fitting and the recess can be circular, polygonal, or polygonal with rounded corners. The fitting and the recess can each be cylindrical or prismatic. Viewed along the cylinder axis, the shape of the lifting fitting and the recess can be polygonal or polygonal with rounded corners, rather than circular.
[0019] The load transfer arrangement according to the invention is particularly suitable for connecting and / or lifting wooden structural components in higher load ranges. The load transfer arrangement can be designed to absorb horizontal and vertical forces greater than 1 kN, 2 kN, 5 kN, or 10 kN. The horizontal force can be between 2 kN and 200 kN, between 5 kN and 175 kN, or between 10 kN and 150 kN. The vertical force can be between 5 kN and 200 kN, between 10 kN and 175 kN, or between 20 kN and 150 kN.
[0020] The first diameter can be at least 50 mm, 100 mm or 150 mm.
[0021] The thickness can be at least 5 mm, 10 mm, 15 mm or 20 mm.
[0022] The fastening screws can have a length of at least 50 mm, 100 mm, 150 mm or 200 mm.
[0023] The number of fastening screws can be at least 4, 5, 6, 7, 8, 9, 10, 11 or 12.
[0024] Advantageously, the fastening screws are arranged at equal intervals across the fitting, and / or in an arrangement where the fastening screws are arranged in a pattern whose center of gravity is approximately at the center of the fastener. Alternatively, the fastening screws can be arranged in a pattern whose center of gravity is not at the center of the fastener, but offset from it. In other words, it can be provided that the fastener is not located at the center of gravity of the fastening screw group, for example, for applications where horizontal and vertical loads occur simultaneously.
[0025] Preferably, the fitting is fully recessed. The depth of the recess can be at least 0.5, 1.0, 1.1, 1.2, 1.3, 1.4, or 1.5 times the thickness of the lifting fitting. Partial recession of the fitting is also possible, in which case part of its thickness protrudes from the recess and the protruding part can, for example, serve as a pin for positioning and
[0026] December 18, 2025 4 / 19 Can serve as a connection with other components.
[0027] The fitting can be at least partially (t>T>0) or completely (T=t) recessed into the wooden component. Furthermore, it is also possible to countersink it (T > t) into the wooden component.
[0028] The initial diameter and thickness of the fitting can be such that the surface pressure between the outer surface of the fitting and the inner surface of the recess allows the transmission of a horizontal force between 2 kN and 200 kN, between 5 kN and 175 kN, or between 10 kN and 150 kN, without exceeding the standard load-bearing capacity of the wood. Furthermore, the required edge distances must be maintained, i.e., the lateral or radial distance between the inner surface of the recess and an outer edge of the wooden component or any opening in the wooden component.
[0029] The fastening element can be an opening in the fitting into which a fastening element can be inserted as a connecting element to a connecting device, e.g., a timber connector attached to the fitting by means of a machine screw. The opening can be provided with an internal thread into which a fastening element with an external thread can be screwed, in particular a metal bolt with a metric external thread. The opening can be provided with an internal thread into which a lifting element with an eyelet can be screwed as a connecting element for inserting a lifting rope or hook, in particular a swivel lifting eyelet (swivel ring). The opening can also be designed without threads, in which case the fastening element could, for example, be a ball-bearing stud.The wooden component may have a blind hole in the base of the recess in the area of the opening, so that the connecting element (fastening element or lifting element) can be fully inserted.
[0030] The fastener can be positioned centrally in the fitting. Alternatively, the fastener can be positioned eccentrically.
[0031] The fitting can have more than one fastening element.
[0032] The fastening element can be a bolt or any other connecting device commonly used in building construction, which serves to connect static loads in a structure.
[0033] The connecting device can be a wooden connector, for example an angle bracket or a tie rod.
[0034] The connecting device may contain metal. The connecting device may include or consist of stainless steel, steel, aluminum, titanium, non-ferrous metals, or their alloys.
[0035] December 18, 2025 5 / 19 The fitting and the connecting device may be made of the same material or of different materials. For example, the fitting may be made of stainless steel and the timber connector of aluminum or an aluminum alloy.
[0036] The wooden component can be a wooden component to be lifted, the fitting a lifting fitting, the fastening element a lifting element and / or the connecting device a lifting device.
[0037] Another aspect of the invention relates to a load transfer system for connecting a first wood or wood-based material component to a second wood or wood-based material component. The system comprises a wood connector comprising a first surface and at least one second surface arranged at an angle to the first surface, wherein the first surface is designed to abut the first wood or wood-based material component and the second surface is designed to abut the second wood or wood-based material component. The surfaces can be arranged at a right angle, or at a right angle ± 30°, or at a right angle ± 20°, or at a right angle ± 10°, or at a right angle ± 5° to each other.
[0038] The system comprises a load transfer arrangement of the type described above with a fitting embedded in the first wooden component for connection to the first surface of the wooden connector by means of the fitting's fastening element.
[0039] The system comprises at least one further load transfer arrangement with a second fitting embedded in the second wooden component, the fitting being plate-shaped with a third diameter, a second thickness, and an outer surface with a central axis, and being embedded in a congruent second recess in the second wooden component, which has a fourth diameter corresponding to the third diameter, a depth at least corresponding to the second thickness, and an inner surface, wherein the second fitting has a number of screw holes extending in the thickness direction, through each of which a fastening screw extends into the second wooden component, wherein the fastening screws are arranged parallel to each other and parallel to the central axis of the second fitting, and wherein the second fitting has a fastening means for connecting to the second surface of the wooden connector.by which a vertical force acting parallel to the central axis of the second fitting and a horizontal force acting perpendicular to it can be introduced into the second fitting, wherein the vertical force can be introduced into the second wooden component via the fastening screws and the horizontal force can be introduced completely or to a large extent from the outer lamella surface of the second fitting via the inner lamella surface of the second recess into the second wooden component.
[0040] December 18, 2025 6 / 19 In other words, the system for the detachable and permanent connection of at least two wooden or wood-based material components comprises a wooden connector with at least two surfaces arranged at an angle to each other, and at least two fittings of the type described above, of which at least one is assigned to one of the two surfaces and is at least partially, preferably completely, received into a corresponding recess in the respective wooden component. The at least two fittings and the corresponding recesses are thus also arranged at an angle to each other.
[0041] The fittings can be positioned with their backs flush against the corresponding surface when mounted. More precisely, the top of each fitting can be positioned flush with the back of the corresponding surface of the timber connector.
[0042] With each of the fittings, shear stresses in the associated fastening screws can be prevented during use by transferring horizontal forces—that is, forces acting essentially perpendicular to the central axis of the fitting—via the outer surface of the fitting and the reveal or inner surface of the recess into the corresponding wooden component. Thus, with each of the fittings, essentially only vertical forces—that is, forces acting in the direction of or parallel to the central axis of the respective fitting—can be transferred via the fastening screws.
[0043] The load transfer system can contribute to providing a suitable, sustainable solution for repeatedly and reliably connecting or disconnecting (assembling and disassembling) timber or wood-based material components arranged at an angle to one another. Simultaneously, it eliminates the need to loosen or reconnect the fastening screws for disassembly and reassembly, and prevents the fastening screws from experiencing damaging stress during operation, even under high loads. These features result in a reliable, durable, and sustainable connection system.
[0044] The load transfer system can further comprise at least one fastening element for each fitting, which is inserted into and engages with the associated fastener to connect the respective fitting to the corresponding surface of the timber connector. The fastening elements can be bolts with external threads, for example, with metric external threads. The fasteners can be openings with associated internal threads, in particular metric internal threads. The timber connector can be an angle bracket, joist hanger, shear plate, or tie rod.
[0045] The features and design described above for the load transfer device
[0046] December 18, 2025 7 / 19 forms may apply accordingly to the further load transfer arrangement.
[0047] Multiple fittings and fasteners can be provided for each wooden component. For example, two or more fittings with corresponding recesses can be provided for each wooden component. One fastener can be provided for each fitting. Thus, two or more fittings can be provided for each first surface and two or more fittings for each second surface of the timber connector. The number of fittings for each first and second surface can be the same or different.
[0048] The fittings and fasteners of the load transfer system may be similar or different from each other in terms of shape, geometry, size and / or extent.
[0049] According to another aspect, the load transfer system of the type described above, together with the two wood or wood-based material components, can constitute a timber construction.

[0057] Detailed the
[0058] The load transfer arrangement 1 initially comprises a wooden component 2 to be loaded by means of a force H (Fig. 2), e.g. a wooden component to be lifted by means of a lifting force H, which is located in the
[0059] The example shown in 8 / 19 of December 18, 2025, consists of a number of cuboid wooden elements 2a glued together (“cross-laminated timber”) and is provided with a cylindrical recess 4. The load transfer arrangement further comprises a fitting 6 recessed into the recess 4, which is cylindrically plate-shaped with a first diameter d, a thickness t, and a cylindrical outer surface f with a cylinder axis Z.
[0060] The recess 4 has a second diameter D corresponding to the first diameter d, a depth T corresponding to at least the thickness t and a cylindrical inner surface F whose cylinder axis coincides with the cylinder axis Z of the lifting fitting 6, apart from any manufacturing tolerances.
[0061] To avoid play, the fitting 6 is inserted tightly into the recess 4, i.e. the first diameter d is practically identical to the second diameter D and, depending on manufacturing possibilities, slightly smaller or even larger than it, in order to ensure the tightest possible fit or even an interference fit.
[0062] The fitting 6 has a number of screw holes 8 which run in the thickness direction or in the direction of a cylinder axis Z of the cylindrical outer surface f of the lifting fitting 6.
[0063] Each screw hole 8 is fitted with a fastening screw 10, the fastening screws 10 also extending parallel to the cylinder axis Z and screwed into the wooden component 2. A flat underside 6a of the fitting 6 rests firmly against a flat base 4a of the recess 4.
[0064] The fitting 6 further comprises a fastening element for attaching a connecting element for connection to a connecting device, e.g., a lifting device. In the illustrated embodiment, the fastening element is formed by a central opening 12 with an internal thread 12a extending in the direction of the cylinder axis Z. As shown in Fig. 4, a lifting element 14, provided with an eyelet, can be screwed into the opening 12 as a connecting element. This lifting element is a swivel hoist ring. The eyelet 16 of the lifting element 14 can serve for inserting a lifting cable or a hook or spreader attached to a lifting cable. The bolt of the swivel hoist ring can represent the fastening element 14, while the eyelet 16 and the base body 18 of the swivel hoist ring together constitute the connecting device 20.
[0065] The eyelet 16 is pivotally connected to the base body 18 of the lifting element 14 about a pivot axis s extending transversely to the cylinder axis Z, so that the wooden component 2 can assume any inclined position during a lifting operation with the lifting force H acting vertically upwards (see Fig. 2), depending on the center of gravity of the wooden component and, if applicable, the position of other components.
[0066] December 18, 2025 9 / 19 terer lifting points. In this process, a vertical force HV directed in the direction of the cylinder axis Z and, if applicable, a horizontal force HH directed perpendicular to it are transferred from the lifting element 14 to the lifting fitting 6, wherein the vertical force HV is introduced into the wooden component 2 through the fastening screws 10 and the horizontal force HH is introduced wholly or mostly from the outer surface f of the lifting fitting 6 via the inner surface F of the recess 4 into the wooden component 2.
[0067] This achieves the advantage that the fastening screws 10 are not subjected to any or almost any shear stress, since the horizontal force is transferred exclusively or to the greatest extent via the outer surface of the lifting fitting and the inner surface of the recess into the wooden component ("hole bearing").
[0068] Corresponding advantages are also achieved in the further embodiment shown in Fig. 5, in which the fastening element 14 is a threaded bolt and the connecting device 20 is an angle bracket with two surfaces 22, 24. The embodiment shown in Fig. 5 serves to connect two wooden components 2 and 3 by means of the angle bracket 20. In the illustrated embodiment, two fittings 6 are inserted into two recesses in each wooden component 2, 3 and detachably connected to the angle bracket 20 via corresponding fastening elements 14, here bolts with metric external threads. As can be seen in the lower part of Fig. 5, the fastening elements 14 each extend into a corresponding blind hole in the respective wooden component.
[0069] The fittings 6 and their attachment in the corresponding recesses of the wooden components by means of fastening or wood screws correspond to those of Figs. 1 to 4. For the sake of clarity, some reference numerals have been omitted in Fig. 5.
[0070] The embodiment shown in Fig. 5 also offers the advantage that the fastening screws are not subjected to any or virtually no shear stress, since the horizontal force is transferred exclusively or almost entirely via the outer surface of the lifting fitting and the inner surface of the recess into the wooden component ("bearing capacity"). Furthermore, this embodiment has the advantage that the wooden components 2 and 3 can be repeatedly assembled and disassembled by tightening or loosening the fastening elements without weakening the connection between the fittings and the wooden components.
