Description

[0001] Title: EXTENDABLE CONNECTING DEVICE FOR CONNECTING BUILDING ELEMENTS TO AT LEAST ONE WOODEN ELEMENT

[0002] The present invention relates to a connecting device for connecting building elements with at least one wooden building element according to the preamble of claim 1.

[0003] Area of ​​application

[0004] The field of application of the present invention is construction for connecting building elements, at least one of which is made of wood. When assembling building elements such as panels, beams, posts, and the like, geometric tolerances often have to be accommodated in order to create a connection between the two elements. Despite these tolerances, a stable and secure connection must be ensured that can absorb the forces that occur.

[0005] State of the art

[0006] DE 203 17 488 discloses a connecting device for structural elements arranged at an angle to one another. A plate having a through-hole is fastened to the end face of the first wooden element. A metal plate having a contour substantially corresponding to the recess in the second wooden element is fastened to the second element. This second metal plate is fastened by means of a series of fastening elements and is connected to the first element by means of a bolt accommodated in a hole through the first metal plate. The described connection does not allow for the compensation of tolerances and the alignment of the fastening elements.CN102125728 also describes a device for connecting components, in which part of the device has a surface which substantially corresponds to the shape of the cavity into which it is inserted and in which it is fixed by means of a series of screws, and the connecting device has a seat in which a bolt is arranged for connection to a second component.

[0007] DE 3641 799 , which also describes an element which is inserted into a cavity of a building element and in which it is fastened to the cavity by means of a series of screws and connected by means of a bolt which is rotatably received by the second element which is fastened to a second building element .

[0008] None of the above-mentioned documents describes a device which can be pivoted within the recess in the component and which also enables the compensation of any lateral, height or orientation tolerances between the two components to be connected.

[0009] Description

[0010] The object of the present invention is to provide a device for connecting at least two components, of which at least one component is made of wood.

[0011] This purpose is achieved by a system according to the characterising part of claim 1 .

[0012] A connecting device for connecting building elements is proposed, of which at least one building element is made of wood, wherein the device comprises a head which has a surface with a segment (sector) of a circular cross-section, which surface has a series of openings as receptacles for fastening means, and wherein the head, which is connected to an element which can be fastened to a second building element in a laterally displaceable and rotatable manner, has a receptacle which receives a bolt on which a connecting element can be arranged so as to be laterally displaceable and adjustable in length and can be connected to a second building element and / or fastened to the latter.

[0013] Advantageously, the head has two side walls connected to the surface with a segment of a circular cross-section, and these side walls advantageously have through-holes that receive the bolt. Advantageously, the bolt is a screw that is tightened to the side walls of the device by means of a nut.

[0014] In the context of the present invention, a circular sector surface is understood to mean a surface with a circular sector-shaped cross-section, i.e. a circular arc.

[0015] The length-adjustable connecting element is inserted between the two side walls of the bolt. The connecting element has a head with a hole into which the bolt is inserted, and the head is advantageously arranged between the two side walls.

[0016] In this way, the circular sector surface can be rotated relative to the bolt and fixed in a cavity / recess of a wooden component. After the circular sector surface has been positioned, fasteners, e.g. screws, are used to fix the head to the component. The circular sector can have an alpha opening a that is less than, equal to or greater than 180°. With an alpha greater than 180°, the connector projects into the space between the two elements to be connected. In this way, the direction of the tensile force of the element in the component can be adjusted. The recess / opening advantageously has at least one circular sector surface. If the circular sector advantageously has an alpha opening (a) of less than 180°, this means that the combination of the two elements of the circular sector forms a full circle of less than 360°.This means that even if the connector is rotated, the end part does not protrude from the interior, thus avoiding the formation of an edge that can cause fitting problems between the panels and allow play in positioning.

[0017] After the head has been attached to the preferably wooden component, it is connected to the connecting element by means of a bolt.

[0018] The connecting element has means for lengthening or shortening, i.e., length-adjustable means. In this way, the connecting element, after being attached to a second structural element directly to the first connecting element, can be tightened to the other structural element by means of a screw or can have a head at the other end, such as is provided for connection to a wooden structural element.

[0019] In a further embodiment, the head of the device with a circular sparkling surface is attached to a second head with a circular sparkling surface or to another element attached to a building element, for example a foundation.

[0020] Further purposes, features, advantages, and possible applications will become apparent from the following description of some embodiments and the accompanying drawings. Accordingly, all features described and / or illustrated in the figures, taken individually or in any combination, constitute the subject matter disclosed herein, regardless of their grouping in the claims or their dependencies, where:

[0026] Figure 6 shows a circular sector with alpha greater than 180

[0027] A device according to the invention is designated in Figure 1 by reference numeral 100. The device 100 according to the invention connects a first wooden structural element 200 to a second structural element 201. Preferably, the system also connects a third structural element 202, which is arranged between the first structural element 200 and the second structural element 201.

[0028] REVISED SHEET (RULE 91) ISA / EP The connecting device 100 has a circular sector head 101, i.e., a surface with a circular sector-shaped cross-section, wherein the circular sector in this embodiment has an opening a of less than 180°. In this way, the head can be aligned in the structural element 200 before fastening, but without leaving the opening / cavity. The circular sector head has a series of holes 101a through which fastening elements 210, e.g., screws, e.g., wood screws, are inserted, which fasten the head 101 to the first wooden structural element 200.

[0029] In a first embodiment, the circular sector head 101 advantageously has two side walls 102 that are connected to the head and are opposite one another. As shown in Figures 1c, 1d, the two side walls 102 each have an opposite through hole 102a, which forms a seat for, for example, a bolt 103.

[0030] In a further embodiment not shown, the receptacle for the bolt is formed by a single wall.

[0031] A connecting element 106 with a head 104 is slidably mounted on the bolt 103. This connecting element 106 has means 105 for adjusting the length of the connecting element 106.

[0032] By laterally displacing the connecting element 104 on the bolt 103, the device 100 according to the invention can be aligned and adjusted. Furthermore, the head 101, which is connected to the connecting element 104 via the bolt 103, can be rotatably aligned within the structural element 200, as a result of which the inclination of the forces within the connection can be adjusted. Furthermore, as shown in Figures 1e, 1f, in the case of a non-ideal arrangement, e.g. if the connecting element 106 is tilted, the connection can be adjusted by rotating the head 101 on the bolt 103. Furthermore, the length-adjustable connecting elements can be used to adjust the tensile force between the two structural elements 200, 201 and the force which they exert, for example, on the structural element 202 lying between the two structural elements 200, 201.

[0033] Figures 1g, 1h, 1i and 1j show how the device 100 according to the invention can compensate for any lateral displacement. By displacing the head of the connecting element 104 on the bolt 103, a possible tolerance in the construction or other assembly problems can be compensated. Advantageously, the connecting element 106 has two threaded parts that are connected to one another via a sleeve 105 that adjusts the length of the connecting element 106. Advantageously, the sleeve 105 has means for improved fastening, e.g., by means of a wrench or the like.

[0034] In the present embodiment of the device 100 according to the invention, the connecting element 106 is connected at its opposite end to a head 101 which has a circular segment surface which is the same as the head arranged at the other end of the connecting device 106. This second head 101 also has two side walls 102 which receive a bolt 103 which is connected to the head of the connecting element 104, and the surface of the head 101 is shaped like a sector of a circle and has a series of holes as receptacles for fastening elements 210, for example screws or the like, and the second head 101 is also fastened to a building element, in this case also a wooden building element.

[0035] After fastening the two heads 101 in the respective, preferably wooden, structural elements, these two heads are connected by means of the connecting element 106, and the length of the connecting element 106 is adjusted by means of the connecting element 105. In this way, a force can be generated between the two structural elements 200 and 201, which generates a force on the third structural element 202. Advantageously, the third structural element 202 is a beam, a plate, or the like, and the first two structural elements 200 and 201 are walls.

[0036] Advantageously, the entire fastening element 100 is arranged in a space formed between the three structural elements. This space is advantageously closed, for example, by a cover 203, 204 made of wood, insulating material or the like. In this way, the connection is not visible from the outside. At a later time, the connection can be easily dismantled or checked for leaks. This may be necessary, for example, at the end of the work in order to check whether the connection formed by the device according to the invention has changed during assembly or whether the load has changed, for example due to the compression of a component during the construction progress.

[0037] Figure 2a shows a second embodiment 310 of the device 100 according to the invention, in which the recess in the component 200 is semicircular, followed by inclined walls which facilitate the insertion of the device 100 according to the invention into the recess.

[0038] As shown in Figure 2d, the operator can access the joint from two different sides during assembly, which are closed after fastening by the covers 204 and 205, so that the operator can assemble the joint while remaining above the support, the panel or the like. To regulate the pressure exerted by the first wooden component 200 and the second component 201 on the third component 202 arranged therebetween, it is advantageous to use the length-adjustable element 106, in particular a sleeve 105, which is used to tighten the joint produced by means of the connecting device according to the invention.

[0039] connection is screwed, adjusted.

[0040] As shown in Figure 1e, the connecting element 106 can be tilted so that the connection can be adjusted even if the two components are not perfectly aligned.

[0041] Figures 3a, 3b, 3c, 3d, and 3f show a further arrangement 311 in which a wooden structural element 200 is fastened to a reinforced concrete structural element 205, for example, a foundation, by means of the device 110 according to the invention. To fasten the device 110 to the reinforced concrete structural element, a connecting element 116 with an anchoring element 117 can be inserted into the formwork into which the reinforced concrete is poured. During curing, the connecting element is fixed in the reinforced concrete by at least partially protruding therefrom.

[0042] The head of the connecting element 114 is fastened to the side walls 112 of the head 111 by means of a bolt 113. Advantageously, the bolt 113 is accommodated in a slot-shaped hole 111a, which allows lateral displacement of the bolt.

[0043] Further variants of the arrangement according to the invention with a connecting device 140 according to the invention are shown in Figures 4a and 4b.

[0044] In the arrangements according to the invention, at least one wooden component 200, 201 always has at least a part of the semicircular and / or hoop-shaped receptacle / opening for receiving the head 101, 111, 141 of the device 100, 110, 120, 140 and 300 according to the invention pivotably within the opening / seat.

[0045] Figures 5a and 5b show further embodiments of an arrangement 350 with a connecting device 360 ​​having a circular sector 301 with a greater than 180°. In this arrangement, the surface of the circular sector offers a larger contact area with the wooden structural element 200 and more space for screw seats. With the connecting element 306, the distance between the two structural elements 200 and 201 can be adjusted and, in addition, the pressure on the structural element 202 can be determined. Access to the assembly area can be closed with the cover 204, which has the advantages described above.

[0046] The connecting bolt enables lateral adjustment between the rim segment element 301 and the head of the connecting element 304.

[0047] In certain situations, such as seismic events, it is desirable for the connecting elements to be able to dissipate energy during the earthquake. In a variant of the invention, a connecting element 106, 116, 146, 306 is provided that is dissipative or is connected to a dissipative element, i.e., capable of plastically deforming without breaking in order to dissipate energy during the earthquake. This element can also be made of metallic material and dissipate energy through deformation.

[0048] Advantageously, the connecting element is shaped so that it can be replaced after an event, e.g., an earthquake, in order to ensure its dissipative properties even afterward. For example, the connecting element may be formed from elastic material or a spring, which no longer guarantees its properties after an event, e.g., an earthquake, or the connecting element 106, 116, 146, 306 may need to be replaced for maintenance purposes and must therefore be replaceable.

[0049] The advantage is that the damping element only acts in one direction and is therefore unidirectional, so that the connection remains under tension in the other direction and thus the connection is guaranteed without the risk of the connection losing its structural stability.

[0050] In a preferred embodiment, acoustic decoupling can be present in the arrangement and / or device according to the invention. This acoustic decoupling can, for example, be a layer of material (e.g., an insulating layer) arranged between the circular sector section head and the component, or it can be arranged on the connecting element 106, 116, 146, 306, for example, a sleeve that acoustically isolates the connection.

[0051] In a preferred embodiment, alpha is less than 180° so that the head can be aligned without protruding from the recess.

[0052] Advantageously, the housing of the head 101, 111, 141, 301 is formed by at least one bore in a side wall connected to the surface-segmented head 101, 111, 141, 301. The bolt 103, 113, 143, 303, on which the connecting element is arranged laterally, is inserted into this bore. This side part is advantageously arranged centrally to the head.

[0053] The variants of the device and arrangement according to the invention described above serve merely to better understand the structure, mode of operation, and properties of the solution presented; they do not limit the disclosure by means of the exemplary embodiments. The figures are schematic, with essential properties and effects sometimes shown significantly enlarged in order to emphasize functions, operating principles, configurations, and technical features.
