Description

DEVICE FOR CONNECTING AT LEAST ONE SURFACE ELEMENT WITH A SUPPORTING STRUCTURE AND / OR AT LEAST TWO SURFACE ELEMENTS AND SURFACE ELEMENT

description

The invention relates to a device for connecting at least one surface element, for example a covering or cladding, to a supporting structure and / or of at least two such surface elements with one another. The invention further relates to a surface covering comprising a supporting structure and at least one surface element attached thereto.

Supporting structures with surface elements are used, for example, in hall construction, in roof and wall constructions, facade cladding, etc. used. The support structures themselves are typically constructed from a modular system of rod elements and node elements and thus form a framework, in particular a space frame, wherein the rod elements are connected to one another during the construction of the framework by means of the node elements. The supporting structures of roof and wall construction can be constructed both single-layered and multi-layered. As weather protection, design element or cover can be arranged between or on or over the elements of the support structure and / or supported on the elements of the support structure surface elements.

For hall and / or roof structures a covering of the supporting structure is usually provided. The roofing or cladding of the supporting structures is formed, for example in hall and / or roof and / or facade constructions, from a plurality of surface elements (Eindeckplatten, roof elements, cladding elements) which are attached to the support structure. This applies in addition to roofs alike for wall structures or curtain wall facades, which also Surface elements are connected to the elements of the support structure to obtain a cover to form a facade.

For example, elements of metal or metal alloys or of plastic come into question for the surface elements, as well as glass panes or surface elements of other such as ceramic materials or composite materials.

In order to cover flat surfaces, different fastening options, such as screw connections, clamping devices, tongue and groove connections and the like are known. A disadvantage of the known fastening systems is that they are indeed suitable for the formation of planar surface coverings, however, a three-dimensional, for example curved surface covering is feasible only with considerable additional effort. For example, for this purpose, the exact inclinations of different surface elements to each other must be planned precisely in advance and made appropriately adapted surface elements for each individual position in individual execution. On-site corrections, for example to adapt to actual requirements, are not or at least hardly possible. This requires a considerable amount of planning and, during assembly, an enormous logistical effort, so that the area element provided for this purpose is always available for each position. This entails corresponding costs for such surface coverings.

Object of the present invention is therefore an initially mentioned

Specify device and a surface coverage, in which the above-mentioned disadvantages are at least partially overcome. In particular, a flexible and movable connection of the surface elements to the support structure and / or the surface elements is to be made possible with each other and thus simplifies the construction and assembly of three-dimensional, in particular curved surface coverings and thus be economically feasible. This object is achieved according to the invention in terms of the device with the features of claim 1 and in terms of the area coverage with the features of claim 14. Advantageous embodiments, further developments and uses are specified in the respective dependent claims.

The inventive device for connecting at least one surface element to a support structure and / or at least two surface elements with each other is designed as a movable joint (in particular hinge) or has at least one movable joint (in particular hinge). This joint comprises at least a first joint element and at least one second joint element which is rotatably cooperating with the first joint element. This means that the first joint element is rotatable or tiltable relative to the second joint element in an assembled state. The first joint element or at least one of the first joint elements is connected to a surface element or connectable, in particular attached to the surface element or attachable or fastened or fastened or integrated or integrable in the surface element, the second joint element or at least one of the second joint elements is with the Support structure and / or at least one further surface element connected or connectable, in particular attached thereto or attachable or fastened or fastened.

The advantages of the invention are in particular that by means of this device, the angle (angle of rotation, tilt angle) between a surface element of a surface covering and an associated support structure and / or between two adjacent surface elements of a surface coverage adjustable and thus at least almost freely selectable. The connection between the surface element and the supporting structure and / or between the surface elements is flexible and movable due to the connecting device according to the invention. For a simple construction and assembly is also three-dimensional, especially curved Surface coverings on structures, in particular three-dimensional structures such as space frameworks, possible because the exact alignment of the individual surface elements can be done by means of the device according to the invention on site during assembly, without requiring the parts must be formed individually for each position. Thus, standard surface elements can be used, which also greatly simplifies the provisioning logistics during assembly. Overall, therefore, the manufacturing cost of three-dimensional, especially curved roof structures can be significantly reduced both due to a simplified design and due to standardizable parts production and simplified logistics and assembly.

Another advantage is that a supporting structure is exposed to a wide variety of loads even after its completion, for example expansion and contraction effects due to changing temperatures or loads due to wind, rain or snow. This also has an effect on the individual surface elements, in particular on their orientation and their angles to one another and to the supporting structure. The device according to the invention can respond flexibly to such changes, for example by adapting the angle to corresponding distortions or

Changes in the structure and / or the surface elements. Also worth mentioning are related burdens and changes that can arise from material changes over the years. Here, the movable connecting device according to the invention can eliminate or intercept or at least reduce the stresses and strains occurring and thereby avoid or reduce damage in the structure as a whole. This can extend the life of a structure or require maintenance and refurbishment at a later date. Overall, the device according to the invention thus provides for a correspondingly flexible surface coverage, which easily adapts to expansion or contraction of the support structure, for example under weather-related temperature fluctuations, by adjusting the angles between the individual surface elements or for carrying capacity. adapt automatically to the construction and thus provide for an appropriate distance compensation. Even heavy rainfall or snow load can be easily absorbed by the movable angle adjustment, which means that the entire construction has flexible application options, even in relation to weather and climatic conditions.

Preferably, the device is designed such that the surface element connected to the first joint element by means of its attachment to the support structure and / or one or more further surface elements and / or after this attachment relative to the support structure and / or relative to the one or more other surface elements the device is movable, in particular rotatable or tiltable. The device is thus designed such that the angle between the surface element and the supporting structure or between adjacent surface elements can be varied, in particular being adjustable in accordance with the respective requirements on site.

A variant embodiment provides that the maximum angle of rotation between the first joint element and the second joint element is 120 °, in particular at 40 °, preferably at approximately 10 °. Accordingly, the maximum rotational or tilting angle between the surface element and the supporting structure, with a corresponding connection of the second connecting element to the supporting structure, is in each case half of the abovementioned values, ie. the surface element can be tilted by up to ± 60 ° relative to the supporting structure, in particular by up to ± 20 °, preferably by up to ± 5 °. Two adjoining surface elements can be tilted against one another by an angle of up to ± 120 °, in particular up to ± 40 °, preferably up to ± 10 °.

A development of the device provides that the first joint element is a built-in element which is incorporated in the surface element, in particular in a lateral edge of the surface element, or which is integrated or can be installed or integrated. The first connecting element preferably has its end Outside anchoring elements for connection to the surface element, preferably by means of bonding, on. As a result, surface element and first joint element or first joint elements during assembly on site form a unit which can be easily attached to one or more second joint elements, which are preferably already mounted on the support structure, and thus form the movable joint of the device. The mounting element thus ensures easy handling and thus for a simple Flächenelementmontagc.

According to one embodiment, the first joint element comprises a base body with a preferably at least substantially cylindrical cavity with a longitudinal axis. The cavity has a slit-shaped first opening extending parallel to its longitudinal axis and is dimensioned such that a first joint element part of the second joint element, at least partially opposite the cavity, is at least partially receivable or received in the cavity, preferably with some play, and Although such that at least a portion of the first hinge member part engages behind an edge of the slot-shaped first opening. Furthermore, a second joint element part of the second joint element projects through the slot-shaped first opening out of the cavity, in such a way that the second joint element is movable, in particular rotatable or tiltable relative to the first joint element. The latter means that the dimensions of the second joint element in the region of the slot-shaped first opening are to be selected or chosen such that sufficient movement clearance remains between the second joint element and the first opening in order to ensure the desired mobility between the first and second joint element.

If the cavity of the first joint element is at least substantially cylindrical and the first joint element part of the second joint element is adapted to this shape, the rotational or tilting axis of the relative movement between the first and second joint element at least almost coincides with the longitudinal axis of the cavity. First and / or second joint element are expediently provided or equipped with suitable means by which they are attached to the support structure and / or the surface or the elements or attachable, in particular fastened or fastened. Optionally, this may also be provided special holding devices.

The second joint element part of the second joint element may have a connection region and / or a fastening plate, in particular a connection region adjoining the first joint element part and a fastening plate adjacent to a side of the connection region opposite the first joint element part for attachment to or in the support structure and / or the further surface element , The connecting region can be designed such that it tapers from the fastening plate to the first joint element part, in particular in its width and / or in its thickness. The mounting plate may have attachment means for attachment to the support structure and / or surface element, in particular at least one hole for forming one or more screw connections. The holes are preferably elongated holes in order to allow a certain tolerance compensation. Furthermore, tolerance compensation can be achieved by introducing washers.

Basically comes for the attachment of the second joint member to the support structure, optionally via a holding device, in addition to a screw by means of one or more screws, a clamping or a snap into consideration.

The second joint element can be inserted in the formation of the first joint part of correspondingly elastic or flexible material, for example of plastic, despite larger dimensions through the first opening into the cavity of the first joint element. The contribution In the cavity, however, can also be done by the training described below.

For example, it may be provided that at least one end face of the cavity of the first joint element, i. in the case of a cylindrical design, a cylinder base surface has a frontal, second opening which corresponds in its size and shape to the cross section of the cavity, so that the first joint element part of the second joint element can be inserted into the cavity via this frontal second opening in the direction of the longitudinal axis. The cavity may, for example, extend over the entire width of the first hinge element, so that the second hinge elements can be pushed into the cavity from the side via the second opening there. This applies in particular when the first joint elements in turn extend over the entire side of the surface element to which they are associated.

It is also possible that a recess is provided in the first joint element on at least one end face of the cavity, which adjoins the cylindrical cavity and at its slot-shaped first opening and extends parallel to the longitudinal axis of the cavity. The dimensions of the recess are matched to the dimensions of the first articulated element of the second connecting element so that the first articulated element can be introduced into the recess, preferably perpendicular to the longitudinal axis of the cavity, and into the cavity, preferably parallel to the longitudinal axis of the cavity of the main body of the first Gelenkεlements is displaceable. After insertion into the cavity, the recess can be filled out of the cavity to prevent it from falling out of the first gel replacement part of the second hinge element, or at least be closed to the outside, for example with silicone.

Of course, the first joint element may also have one or more end openings second and / or one or more openings of the type described above. In a further development of the device according to the invention, it is provided that the second joint element has first joint element parts on two mutually opposite sides, which each interact in a rotationally movable manner with a first joint element. The second joint element is thus a double joint element, via which two surface elements can be connected or connected to one another and / or to the supporting structure. This reduces the number of parts required, makes assembly easier and quicker.

The second joint element can also be designed star-shaped with a central base element and with three or more arranged around the base element first joint element parts, which cooperate in each case rotatably with a first joint element. A corresponding number of surface elements can thus be connected to one another and / or to the support structure via such a multiple steering element.

According to a further embodiment, one or more holding devices can be provided for connecting the device with and / or for fastening the device to the supporting structure. The holding device can in particular define the distance of the surface elements to elements of the supporting structure in such a way that the desired turning or tilting angle can be set. It can also fulfill a simpler installation and better accessibility of the various mounting elements.

The individual elements of the device according to the invention, for example first and second joint element and possibly also holding device are in their shape design as well as in the choice of materials and their arrangement and the nature of their attachment or attachment or integration on a surface element or on the support structure depending on the desired rotation or tilt angle and / or the weight of the surface elements and / or their shape and / or their material. Considered, for example, is a construction of first and / or second joint element of metal, in particular of aluminum, preferably of aluminum extrusion parts, and / or of steel, preferably cast steel. But also plastic and combinations of all the above materials are possible.

To prevent noise and / or wear and / or corrosion phenomena, it is possible to provide at least the cavity of the first joint element and / or the first joint element part of the second joint element with a coating.

As already mentioned, the use of the device according to the invention is advantageous for producing a surface covering comprising a supporting structure and at least one surface element. By means of the device, at least one movable connection is formed between the surface element or at least one of the surface elements and the support structure, in particular at least one element of the support structure, and / or between the surface element and at least one other surface element. This movable connection allows the setting of a tilt angle between surface element and support structure and / or other surface element, for example, according to a predetermined shape of the surface coverage to be produced.

The surface covering according to the invention comprises a supporting structure and at least one surface element. The surface element or at least one of the surface elements is connected to the support structure, in particular at least one element of the support structure, and / or at least one other surface element via at least one inventive device movable, in particular rotatable or tiltable connected. The advantages of this surface coverage result from the advantages of the device explained above. In particular, the area coverage is simple, fast and inexpensive to produce. Furthermore, it results from the use of the device according to the invention a great creative freedom in the design of the area coverage. Even three-dimensional, curved shapes can be realized with relatively little effort and thus cost. Finally, the movable connection of the elements of the surface covering with each other and / or with the support structure for a high flexibility, which increases the life of the surface covering and also extreme loads, such as large temperature fluctuations and unfavorable climatic conditions withstands.

The first joint element or at least one of the first joint elements of the device is preferably connected to the surface element, in particular incorporated or integrated in the surface element, and / or the second joint element or at least one of the second joint elements is connected to the support structure and / or at least one other Surface element connected, in particular attached and / or attached.

The surface elements may be, for example, metal plates, for example made of stainless steel or aluminum alloys. These are suitable, inter alia, as facade, wall elements or roof elements, for example, to form a shade roof. For this purpose, the surface elements may be perforated in a suitable manner, for example, they may be formed as perforated plates or perforated plates. However, the surface elements may also be glass or plexiglas plates, with or without a socket, wherein the socket can again be a plastic socket or else a metal socket or even a socket made of a composite material. Also surface elements made of composite material or ceramic are conceivable, depending on the requirement. In particular, the surface elements may each comprise two parallel panes, in particular glass panes, which are connected to one another at their edge, in particular by bonding, preferably by means of silicone adhesive. Usually, the two disks are spaced from each other, for example by means of suitable spacers between the disks. The first joint element or at least one of the first joint elements of the device can then be incorporated or integrated into the edge connection between the glass panes, in particular by adhesive bonding, preferably by means of silicone adhesive. The first joint element is in this case a built-in part. This creates a simple to handle during assembly and also in the deployment logistics unit of surface element and hinge element.

Depending on the application, it may be expedient that a plurality of first hinge elements are provided in series on at least one side edge (also: side edge) of a first surface element. But it is also possible that the first joint element extends over the entire length of one of the side edge. In this case, for example, a correspondingly dimensioned second joint element can be assigned to the first joint element, that is to say it also extends at least almost over the length of the side edge of the surface element. But it is also possible that a plurality of shorter-sized second hinge elements are assigned to this first joint element, for example by these are inserted in series in the first joint element.

Furthermore, a plurality of first hinge elements may be provided in series at the side edge of a second surface element adjacent to the first surface element, such that the first hinge elements of the first surface element and the first hinge elements of the second surface element in the surface coverage along the adjacent side edges of the two Surface elements are arranged offset from one another and each first joint element is assigned at least one own second joint element in a corresponding orientation. It is also it is possible for the first joint elements of the first surface element and the first joint elements of the second surface element in the surface covering to be arranged opposite one another along the adjacent side edges of the two surface elements and for each opposing pair of first joint elements to be at least one second joint element configured for movable cooperation with at least two first joint elements , assigned. In this case, the second joint element is a double joint element.

At least one sealing and / or damping element, in particular of flexible material for accommodating rotational or tilting movements of the surface element, preferably a sealing strip, may be provided between the surface element or at least one of the surface elements and the support structure. As a result, for example, noise, wear, corrosion and water and dirt entry can be avoided or at least reduced.

For reasons of sealing, but also for design reasons, for example in order to obtain a uniform, smooth surface, it may also be expedient, after the assembly of the surface elements, to fill the interstices between adjacent surface elements of the surface covering, in particular to eject them, for example with silicone. With such a filled or sprayed-in area covering, the articulated connection of the individual area elements to one another or to the supporting structure is no longer to be seen.

The supporting structure of the surface covering may be a single-layered construction or a two- or multi-layered space frame comprising the bar elements and, as a rule, node elements. The elements of the support structure, such as node elements and rod elements, may be formed of steel, in particular galvanized steel, stainless steel, stainless steel or aluminum. Furthermore, for these elements, fiber composite materials, such as carbon fiber reinforced Plastics (CFRP) and / or glass reinforced plastics (GRP), are used.

Overall, the invention provides a device for connecting a surface element with a supporting structure or of surface elements with each other, by means of which in a simple manner, with little staff, quickly and inexpensively surface elements are mounted in each provided inclination. Furthermore, the invention advantageously allows the formation of a curved, rounded or wavy Flächeneindeckung.

The invention will be explained in more detail below with regard to further features and advantages with reference to the description of embodiments and with reference to the accompanying schematic drawings. Show

Corresponding parts and components are provided in the figures with the same reference numerals.

FIG 1 and FIG 2 show a roof construction 10 in a perspective view. FIG 1 and FIG 2 show only a support structure 54 of the roof structure 10, a surface covering 1 1 of this roof structure 10 is not shown to illustrate the support structure 10 here. Possible surface coverings are shown in FIG. 3 and FIG. 4 and explained below.

A part of the roof structure 10 is in the form of a barrel vault 12, a subsequent thereto further part of the roof structure 10 is formed as a wavy curved roof 14. The latter is shown enlarged in FIG. The roof construction 10 comprises, as can be seen in FIG. 2, a two-layered room-type work. The space framework is of modular construction, with bar elements 16 being connected via node elements 18. are connected in such a way that essentially two parallel superimposed, here corrugated surfaces of rod elements 16 and node 18 result. Furthermore, in FIG 1 and FIG 2 supporting pillars 19 of the space frame can be seen.

The arched roof construction according to FIG. 1 and FIG. 2 can have a surface covering 11 according to the invention, ie this is formed using a variant of the device 22 according to the invention for connecting at least one surface element 44 to the support structure 54 and / or at least two surface elements 44 to one another , For this purpose, it is for example possible to connect the surface elements 44 via the device 22 with the rod elements 16 or the node elements 18 of the support structure 54 or generally with elements 52 of the support structure 54. At the same time, adjacent surface elements 22 can be connected to one another via the device 22.

FIG. 3 shows, in a side view, schematically an example of a surface covering 11, formed from numerous individual surface elements 44. These, which can not be seen in FIG. 3, are connected to one another via devices 22 according to the invention;

Devices 22 may be attached to a support structure 54. At least some of the surface elements 44 are inclined relative to each other, whereby the wave-shaped form of the surface covering 11 shown here arises. After mounting the surface elements 44, the spaces between the surface elements 44 were seen to be injected with silicone, so that only joints 45 are visible in this way to the outside. This results in a uniform, smooth surface of the surface covering 1 1, the devices 22 in the interstices are not visible.

FIG. 4 shows, in a plan view, schematically another possible surface covering 11, as may be provided, for example, in the roof construction 10 according to FIG. Here is the exemplified arrangement of the individual surface elements 44 to recognize each other. The individual areas chenelemente 11 may of course be inclined to each other to form a curvature, which is not apparent in the plan view.

FIGS. 5 to 10 show an embodiment of a device 22 according to the invention. 5 shows a side sectional view of the use of the device 22 for the movable connection of surface elements 44 with a support structure 54, FIG. 6 shows this arrangement in plan view. The device 22 comprises a joint formed by a first joint element 32 and a second joint element 20. It can be seen from FIG. 6 that each surface element 44 is movably connected to an element 52 of the support structure 54 via a plurality of devices 22. Each device 22 comprises a first hinge element 32 and a second hinge element 20, wherein the first hinge element 32 is integrated in the surface element 44 and the second hinge element 20 is fastened via a holding device 56 to the element 52 of the support structure 54. The individual devices 22 are arranged offset to each other in series along the adjacent side wheels of the two surface elements, in such a way that the devices 22 are determined alternately for each of the two surface elements, so that the overall result is a zipper-like arrangement. In this way, the two surface elements 44 can be mounted independently and quickly independently. Both surface elements 44 are independently movably connected to the element 52 of the support structure 54. The tilt angle (also: angle of inclination) of each surface element 44 relative to the support structure 54 can thus be adjusted individually.

The section in FIG. 5 is not continuous; rather, the section through the left surface element 44 and the associated device 22 is in the direction of the plane of the drawing before the section through the right surface element 44. By this representation, the function of the devices 22, the inclination of the surface elements 44, illustrate. 7 shows in a side view and FIG. 8 in a plan view the second joint element 20 of the device 22 from FIG. 5 in isolation. 9 shows in a side view and FIG. 10 in a sectional illustration along the line AA in FIG. 9 the first joint element of the device 22 from FIG. 5 integrated into the surface element 44. From this illustration, the embodiment is described in conjunction with FIG the joint during assembly of the surface element 44 to the support structure 54 and the interaction of the joint elements 20, 32 for realizing the desired movable connection between surface element 44 and support structure 54 and thus also the adjacent surface elements 44 to each other. The joint works here like a hinge and thus allows a Kippbzw. Rotational movement of the respective surface element 44th

The second joint element 20 comprises a first joint element part 26, which is received in the assembled joint in a corresponding cavity 36 of the first joint member 32. This first joint element part 26 is in the illustrated embodiment, the essential part of a cylinder, the cavity 36 is also substantially cylindrical, with a lateral slot-shaped first opening 40, from which the second joint member 20 protrudes. The rotational movement between the first joint element 32 and the second joint element 20 takes place about the central axis of the aforementioned cylinder of the first joint element part 26 which coincides with the central axis of the aforementioned cavity cylinder of the cavity 36. In the case of a plurality of devices 22 arranged one behind the other with respect to a surface element 44, as for example in FIG. 6, the above-mentioned central axes of the individual devices 22 must lie on a straight line.

The first joint element part 26 is adjoined by a second joint element part 27, which projects out of the first opening 40 of the cavity 36. This second joint element part 27 comprises, adjacent to the first joint element part 26, a connection region 28 to which in turn a fastening plate 24 adjoins. The connection region 28 tapers off starting from the mounting plate 24 in the direction of the first joint element part 26 both in terms of its width and in terms of its thickness. The first joint element part 26 extends with a length L along the width of the connection region 28, parallel to the transition between connection region 28 and attachment plate 24.

In the example shown here, two elongated holes 30 are provided in the fastening plate 24, via which the second joint element 20 is fastened by means of screw connections to the supporting structure 54. This attachment with a screw 58 is shown in FIG. 5, specifically the attachment to the element 52 of the support structure 54 takes place here via the already mentioned holding device 56. Optionally, in the context of the screw connection during installation suitable inserts or washers for a exact height adjustment of the second joint member 20 are arranged. Alternatively or in addition, however, other fastening variants or fastening means come into consideration, for example bolts or clamps (not shown) or even snap-in, gluing and / or welding. The elongated holes 30 allow easy handling during assembly, since the exact mounting position during assembly is still variable and thus a location-accurate placement of the second joint member 20 can be made locally. This gives the possibility for tolerance compensation.

The first joint element 32 of the device 22 shown in FIG. 9 and FIG. 10 comprises a base body 34 which has a substantially cylindrical cavity 36. The cavity 36 is dimensioned so that it can preferably accommodate the likewise substantially cylindrically shaped first joint element part 26 of the second joint element 20 with some play. Furthermore, a first slot-shaped opening 40 of the cavity 36, which runs parallel to the longitudinal axis 35 of the cylindrical cavity 36, is provided, through which the second joint element part 27 of the second joint element 20 projects out of the first joint element 32, when the second joint element Steering member 26 of the second hinge member 20 in the cavity 36 of the first joint member 32 is located.

In cases where the body 34 of the first mounting member 32 is formed of a relatively soft or elastic material, such as a plastic, the first joint member 26 can easily pass through the slot-shaped first opening 40 into the cavity 36 of the first joint member 32 be introduced. If the base body 34 of the first joint element 32 of a relatively rigid, inelastic material, such as steel or Aluminiumgus s, formed, for example, at least one of the end sides of the cavity 36, a second opening may be provided for the insertion of the second joint member 20 in the cavity 36 (not shown). However, it is also possible, as shown in FIG 9 and FIG 10, a to the slot-shaped opening 40 and the cavity 36 at one of its end faces adjoining and also provided in the direction of the longitudinal axis 35 of the cavity 36 extending recess 42. Of course, this also applies to the formation of the main body 34 of relatively soft or elastic materials. Also, one or more second openings and / or one or more recesses 42, for example, on both end sides of the cavity 36 may be provided simultaneously.

This recess 42 in FIG. 9 and FIG. 10 largely corresponds in its cross-sectional shape to the cross-sectional shape of the cavity 36, only the constriction at the first opening 40 is omitted (see FIG. 10). The length of recess 42 is at least as large as the length L of the first joint element part 26 with some play. The height H of the recess 42 corresponds with some play at least to the diameter D of the first joint element part 26 (see FIG. 7). This height H also has the recess 42 at its opening, so that the first joint element part 26 of the second joint element 20 can be easily inserted into the recess 42. For this purpose, the first joint element part 26 is inserted into the recess 42 perpendicular to the longitudinal axis 35 of the cavity 36, until it is pressed against the rear wall of the recess. ment 42 strikes. Then the first joint element part 26 is displaced parallel to the longitudinal axis 35 into the cavity 36 of the main body 34 of the first joint element 32, so that the second joint element part 27 of the second joint element 20 protrudes from the slot-shaped first opening 40 of the first joint element 32 (see FIG. 5 in FIG Connection with FIG. 9). The recess 42 may be filled or at least closed after installation with silicone adhesive, so as to prevent falling out or slipping out of the second joint member 20 from the cavity 36 of the first joint member 32.

The main body 34 of the second joint element 32 may be screwed, for example, with a surface element 44 or connected in any other way with this or attached thereto. In the example according to FIG. 5 to FIG. 10, the second joint element 32 is a built-in element integrated into the surface element 44. The surface elements 44 each comprise two parallel, spaced by spacers 50 glass sheets 48. The second joint member 32 is installed in each case via an embedding of silicone adhesive 46 between the two disks 48 of each surface element 44 and thus integrated into the surface element 44. For better adhesion in the silicone adhesive 46, the base body 34, as shown in FIG. 10, has a structured surface with protruding anchoring elements 33. Overall, the surface element 44 thus forms here a Hohlkammet- profile.

The silicone adhesive 46 glues the two glass panes 48 in their edge region. Against the interior of the surface element 44, the edge region in the example shown is delimited by the already mentioned spacer element 50 (also: spacer). This spacer element 50 is arranged at a predetermined distance from the edge of the glass panes 48 offset inwards and holds the panes of glass in two parallel planes. In addition, it acts as a limitation for the gluing of the glass panes 48 and the integration of the first hinge elements 32 to be introduced silicone adhesive 46th Of course, instead of the surface elements 44 shown here, two parallel glass panes 48 (likewise suitable for Plexiglas panes or PC panes) may also be surface elements comprising only one pane 48 made of ceramic, a composite material, metal, metal alloy, in the form of plates, perforated plates, Sheet metal etc. may be provided in connection with the use of the device 22 according to the invention.

Finally, in FIG. 5, the already mentioned element 52 of the support structure 54 is finally shown in cross section. In this case, a hollow profile is attached to which the device 22 is attached via the already mentioned holding device 56 (here a holding web, for example a flat iron, but for example also a threaded bolt, a threaded sleeve, a clamping profile or the like). Likewise, as an alternative to the hollow profile of course, pipes or angle profiles or other types of rod elements into consideration. The attachment can - as shown - done by means of screwing, but it is also possible, for example, a weld. Between the surface elements 44 and the element 52 of the support structure 52, a flexible sealing and / or damping element is arranged in each case. Of course, at other locations of the arrangement, in particular between moving parts and / or in the region of the screw, sealing and / or damping elements, for example, such as Unterbinduno- unwanted crunching noise, be provided.

As shown in FIGS. 5 and 6, the first joint elements 32 are provided on one or more side edges of the surface elements 44. Their number and design is adapted to the length of the side and the weight of the surface elements 44. The choice of material and detailed design of the various components of the device 22, in particular he hinge demes 20 and 32 depends essentially on the weight of the surface elements and also on the material of the respective counter-element or other contacting elements, for example, wear and contact corrosion and other negative or as low as possible keep or avoid. Optionally, it is useful to provide individual area, for example the cavity 36 and / or the first joint element part 26 with a suitable coating. This can also counteract unwanted noise.

5 shows a total of an embodiment of the device 22 according to the invention in its intended use. In the example shown, two adjacent surface elements 44 are connected by means of the device 22 via a holding device 56 with an element 52 of the Tragkonstrukti- on 54, as may be used, for example, in the roof structures 10 in FIG 1 and FIG. The surface elements 44 are due to their attachment or attachment via the devices 22 in the example shown here in its angle relative to the support structure 54 tilted or inclined, the tilt angle of the left Flächenele- element 0 ° and the right surface element is about 10 ° , In principle, this angle is almost freely selectable or adjustable for each surface element. The holding device 56 of the device 22 is formed in FIG 5 in the form of a flat iron and welded to the element 52 of the support structure 54.

The device 22 according to the invention can, instead of having a plurality of individual small second clamping elements 20 and matching small first hinge elements 32 distributed over the side edge of the planar element 44, be provided with a single second hinge element 20 extending over the entire length of the side of a planar element 44 and a correspondingly matching second hinge element 32 may be equipped. Also, a plurality of second hinge members 20 may be received in a first hinge member 32. It is useful to use elongate elements or elements 32, 20 extending over the entire length of one side, for example with high-weight surface elements 44.

In order to allow a certain tolerance compensation, the first joint elements 32 within the second hinge elements 20 can be longitudinally displaced be. Furthermore, in each case a certain amount of play can be provided here at the corresponding dimensions.

If two surface elements are to be mounted opposite one another, it is also possible to use specially configured joint elements 20, which are formed on two mutually opposite sides with joint element parts. A corresponding example is shown in FIG 11. This is particularly useful when elongated elements 20, 32 are used. The further embodiment of the double joint element 20 in FIG. 11 corresponds to the design of the second joint element 20 in FIG. 7 and FIG. 8, except that connecting regions 28 adjoin the fastening plate 24 with their oblong holes 30 on two opposite sides, which extend in opposite directions extend and taper and in each case ends in substantially cylindrical first hinge element parts 26. The first joint element parts 26 extend parallel to one another perpendicular to the plane of the drawing in FIG. 11.

These specially designed joint elements 20 could be formed in one piece. However, it is expedient to have a two-part construction, as shown in FIG. The left side of the joint element 20 in FIG. 11 is formed by a first part 62 and the right side in FIG. 11 by a second part 64. The parts 62, 64 are identical in their construction, they are merely associated with one another in such a way that a part is turned over. Both parts 62, 64 overlap in the mounting position shown in FIG 11 in the region of the mounting plate 24 with the slot 30, in such a way that each part 62, 64 forms the complete cross section of the elongated hole 30 in plan view (see FIG 8) , The two-part design makes it possible for the parts 62, 64 to be mounted independently of one another on the respective surface element 44 during assembly, the attachment to the support structure 54 can then take place successively, with the surface element 44 already connected to the part 62 or 64. The two-part design also allows height compensation between the surface elements 44 to be arranged on both sides. The decisive advantage is that the two-surface design of the specially designed joint elements 20, the two surface elements 44 are independently mounted, which brings a considerable ease of assembly with it.

The respective central axes of the cylinders of the first joint element parts 26 of the specially designed joint element according to FIG. 11 should expediently be aligned for the respective side in such a way that they lie exactly on a respective desired straight line, and the straight lines of both sides should advantageously be aligned as much as possible during the month be alignable so that they are at least largely in one plane. As a result, dislocations between adjacent surface elements 44, which can lead to unevenness in the overall surface, can be avoided. The arrangement on each side of a straight line is also important to stresses within the surface element 44, which otherwise occur in particular in the attachment of the surface element 44, when moving the surface element 44 by means of the device according to the invention or under loads of the support structure or the surface element can and should lead to damage of the surface element 44, to avoid.

It is clear to the person skilled in the art that in the device 22 according to the invention, instead of a connection with a hollow profile, it is also possible to connect it to any other element 52 of a supporting structure 54 that has been designed in a meaningful way, for example also a node element. The distance that the holding device 56 creates from the element 52 of the support structure 54 depends inter alia on the angle at which the surface element (s) should be tiltable, and of course on the shape of the surface elements 44. In particularly favorable cases It may also be possible to connect the device 22 according to the invention directly to the element 52 of the supporting structure 54 instead of via a holding device 56.

Instead of the second joint elements 20 according to FIG. 7 and FIG. 8 as well as according to FIG. 11, it is also conceivable to use a star-shaped second joint element with a central base plate and a first one extending around the base plate To provide hinge member parts 26, wherein the first hinge member parts 26 may extend around the base plate, for example in the form of a polygon and / or a closed ring around. Flat elements 44 with very short sides or with their corners can then be articulated to the first joint element parts 26 of such a second joint element 20.
