Description

[Technical Field]

[0001] The invention relates to a system for connecting at least two structural parts, at least one of which is a wooden part and at least one of which is a beam, according to the characterizing part of claim 1, and to a device for this system.

[0002] The field of application of the present invention is structures for connecting structural components, at least one of which is made of wood. When assembling structural components such as panels, beams, columns, etc., the problem of moment transfer and the zonal elements to which this moment is applied arises. This problem complicates the design and static calculations of the structure in question. [Background technology]

[0003] EP3985189 discloses a connector for two components. It has two connection sections, each having a mounting side for the components and an opposite connection side, so that the two connection sections can be connected to each other in a suspension direction parallel to the connection sides. Each connection section has a shoulder on its connection side, transverse to the suspension direction. The shoulder has a notch that runs across its entire width, transverse to the suspension point, leaving a core in the bead. The end face of the shoulder away from the bead and adjacent to the connection side has a lip that runs across its entire width and is adjacent to the connection side. In the first locking position of the fittings, the lip of each fitting engages with the notch of the other fitting.

[0004] German Patent Application No. 112011101146 (DE112011101146) shows a metal mounting connector, by means of which a support element, such as a bracket, and a connecting element, such as a bracket, are connected to one another in a T-shape. The metal mounting connector is designed so that its front edge, intended to be attached to one side of the support member, is spaced apart from its rear edge, intended to be inserted into a shaped slot in the connecting element and secured by an interlocking pin or the like. The front and rear edge parts are connected to one another only by a plurality of branch-shaped parts. A second connecting element is inserted into a second structural part, which means that the connection does not allow any rotation between the two connecting elements.

[0005] International Publication No. 2021151097 (WO2021151097) describes a connection between a first structural element and a second structural element formed with a connector. The connection comprises a first structural element, a second structural element, and a connector. The connector comprises a first connector element secured to the first structural element by one or more angled fasteners received by the first connector element and the first structural element, and a second connector element secured to the second structural element by one or more angled fasteners received by the second connector element and the second structural element. The connector has a longitudinal axis extending from an upper portion of the connector to a lower portion of the connector. The one or more angled fasteners received in the first structural element and the one or more angled fasteners received in the second structural element are arranged at a non-orthogonal angle relative to the longitudinal axis. The first connector element has one or more elongated slots that receive one or more angled fasteners that are received by the second structural element, and the second connector element has one or more elongated slots that receive one or more angled fasteners that are received by the second structural element.

[0006] EP3366855 describes a device for connecting two vertical components, which consist of a beam made of wood, particularly glue-laminated lumber, and a connector for each end face of the beam to connect the end face to one of the vertical components. Each connector has two fittings, one of which can be fixed to the end face of the beam using one side and the other of which can be fixed to the respective vertical component using one side. The connector can be brought into contact with the other side and has two clamping jaws on both ends of the diameter that can be clamped to each other by at least one clamping element, running generally parallel to the other side. The beam has a steel lower chord that is fixed at each end face of the beam to a fitting attached thereto using at least one clamping element. This clamping element is provided to tension the lower chord.

[0007] EP3456892 also describes a connector for connecting two wooden parts at their end faces.

[0008] All of the above documents suffer from the problem of rigid behavior, so that moments are transmitted between two structural parts, and in addition the pivot points cannot be predefined, which makes static calculations difficult.

[0009] WO 2020 / 234111 A1 discloses a device for connecting parts, which comprises at least one pair of connecting elements, each of which is anchored to the first element to be connected, and a second connecting element anchored to the second connecting element and capable of coupling to the first connecting element. The first connecting element is connected to the second connecting element by squeezing it. In this type of connection, torque is also transmitted, and the connection does not allow rotation.

[0010] Japanese Patent No. 5234382 discloses a connection plate for connecting the end face of a horizontal member to the side face of a beam. This connection plate is fixed to the side face of the beam and protrudes from the connection plate to the side of the horizontal member. The connection is made by inserting the connection plate into a groove formed vertically in the end face of the cross member. The connection plate is a rod-shaped connection element that passes through the cross member.

[0011] The connecting plate engages the structural part and no longer allows rotation, so that the force moment is transmitted.

[0012] According to the art, beams are often calculated as supported, so there are no moments between elements. [Prior art documents] [Patent documents]

[0014] The object of the present invention is to provide a system for connecting at least two structural parts, at least one of which is made of wood and at least one of which is a beam, and a device for said system, wherein the connection formed by the system allows rotation between the structural parts, so that the connection can be considered in calculations as a perfect hinge, i.e. as if it does not transmit any moments. [Means for solving the problem]

[0015] This goal is achieved by a system according to the characterizing part of patent claim 1.

[0016] A connection system is proposed, comprising a connection device for connecting two structural components with two opposing surfaces. At least one of the structural components is a wooden element and at least one is a beam. The connection device comprises a first element and a second element, each having a base plate and each of which is fixed to the structural component. One of the two device elements has two flanges that form seats for one or more flanges of the other device element, which are substantially parallel to each other. The flanges of the two elements are substantially perpendicular to the base plate, and at least one of the flanges of the device element has a V-shaped opening, advantageously located at its upper end, and the flange of the device element with the V-shaped opening has at least one opening (hole) extending substantially horizontally. The other device element has at least one flange, which has a series of substantially circular holes, and the horizontal elongated holes in the first device element are associated with the circular holes in the second device element and are connected by pins. The holes in the second device element are connected to the V-shaped openings in the first device element.

[0017] When two flanges are present on the device element, both flanges have upwardly facing openings, for example V-shaped openings.

[0018] A V-shaped opening is any opening that is open at the top.

[0019] This system allows for the definition of the axis about which rotation occurs between two structural components. This particular axis is the axis about which forces act. By defining the range of rotation along this axis, the forces in the system can be better defined.

DETAILED DESCRIPTION OF THE INVENTION

[0023] The device according to the invention is designated by the reference numeral 100 in FIG. 1a.

[0024] The system according to the invention uses a device 100, 120 for connecting two structural components 201, 202 (Figures 3a-3b, 4a-4d, 5a-5c, 6), at least one of which is a wooden element and at least one of which is a beam.

[0025] The device 100 comprises a first element 101 and a second element 110. Advantageously, both elements 101 and 110 are made of metal. Each element has a base plate, which is fixed to a respective opposing structural part 201, 202 by a series of fixing elements 203, 204, advantageously by bolts and / or screws, and fastened by nuts.

[0026] Each element 101, 110 of the connection device 100 according to the invention has at least one flange. At least one element 101, 110 has at least two flanges extending substantially perpendicular to the base plate and a respective fastening surface of the element on the structural part 201, 202. One element 101, 110 has a series of substantially circular holes in the flange, while the other element has a series of elongated holes in the flange extending perpendicular to the base plate and a mounting surface of the element 101, 102 on the structural part 201, 202.

[0027] After the individual elements 101, 110 are anchored to their respective structural components 201, 202, in this embodiment, pins and / or anchoring elements are inserted into holes in the upper end of the second element 110. The second structural component with the anchored element 110 is then guided toward the first structural component with the anchored first element 101. The flanges of the respective elements are aligned, and bolts or anchoring elements are inserted into the V-shaped, or upward-facing, openings 102 in the flange of the first element. The upward-facing openings, e.g., V-shaped openings 102, facilitate the access of this type of connection, allowing rotation between the two elements 101, 110 and enabling alignment of the structural components. After alignment, pins and / or connecting elements are used to connect the two elements. The resulting connection allows for the definition of an axis forming a pivot point between the two elements. This axis 200 facilitates calculations, and therefore the design of the structure, by better determining the forces within the structure.

[0028] Advantageously, both the first element 101 and the second element 110 each have two flanges, the flanges of the first element externally surrounding the flanges of the second element 110 when the device 100 according to the invention is in the assembled state.

[0029] A particularly advantageous embodiment is shown in Figures 2a to 2g.

[0030] The first element 131 of the connection device 120 comprises a flange and a base plate, which is advantageously connected to a structural part, for example a wooden structural part of the plate, by means of fastening means, for example screws, passing through openings 134.

[0031] The flange of the first element 131 has an upwardly facing opening, preferably a V-shaped opening 132 at its upper end, and a series of substantially horizontally elongated openings 133 .

[0032] The second element 121 of the connection device 120 has two flanges. The second element 121 has a base plate, which is connected to a structural component, advantageously a wooden beam, by fastening means, such as screws, passing through openings 122. The two flanges of the first element 121 have a series of substantially circular holes 123.

[0033] During assembly in a first step, each element 121 and 131 is attached to a respective structural part.

[0034] In a second step, in this embodiment, a pin, screw, bolt, etc. 205 is inserted into the top opening in the second member 121 .

[0035] In a third step, the second element 121 is brought close to the first element 131, a pin, screw, bolt, etc. 205 is received in the upper opening 132, and the flange of the first element 131 is inserted between the two flanges of the second element 121.

[0036] In a fourth step, a pin, screw, bolt or the like 205 is inserted through the substantially horizontally elongated hole 133 in the first element 131 and the substantially circular hole in the second element.

[0037] The horizontal slots are preferably spaced 8 mm apart, ie ±15 mm, particularly preferably ±4 mm.

[0038] In a preferred embodiment, as shown in Figures 3a and 3b, the second element 150 comprises an insert 151 that is inserted into a slot in the second part 202 and secured by a series of pins and / or screws 206.

[0039] Figures 5a, 5b and 5c show that the pin 205 is inserted into a slot in the flange of the first element. As can be seen, the play provided by the substantially horizontal slot allows for adjustment of the connection and for the robustness of the connection between the first and second structural parts 201, 202.

[0040] In a preferred embodiment, a gap is formed between the first and second structures 201, 202 by the connection device 100, 120, 140. Between the first and second structures 201, 202, the space is at least partially filled with a fire-retardant material, for example foam. In this way, the connection device 100, 120, 140 is protected from heat. The play between the two elements of the connection device can be used to adjust the gap.

[0041] Advantageously, the lateral play (tolerance) between the first and second elements is between 1 and 11 mm, ie ±5 mm, particularly advantageously ±1.5 mm, ie 3 mm.

[0042] Advantageously, after the first element has been mounted to the second element, the second element can rotate relative to the first element about the pivot axis 205 by ±6°, preferably ±3°.

[0043] Finally, it is clear that additions, modifications or variations to the method and connecting plate described herein may be applied, which would be apparent to a person skilled in the art, without departing from the scope of protection afforded by the appended claims.
