A device for securing façade components (1) to a building (2) has securing components which engage with the building (2) and the façade components (1). The latter have, on opposite corners, an edge bent towards the building (2) and an inwardly facing bead (4). U-shaped retaining sections (5) with two shanks (6) projecting from the building (2) are secured to the building (2). Between their shanks (6) these retaining sections (5) accept rod sections (13) with a domed cross-section which span at least two retaining sections (5), can be solidly secured to the retaining sections (5) at optional distances from the building (2) and have laterally projecting webs (14) running parallel to the beads (4) of the façade components (1). There are also clamping lugs with a threaded drilling, one jaw surrounding both a web of the rod section and a bead (4) of the façade component. On the rod section (13) are fitted tensioning bolts with a male thread which can rotate and are axially fixed and which pass through the threaded drilling in a clamping lug and, when rotated, cause the clamping lug to move relatively to the web (14) and bead (4) so that the latter can be clamped in the jaws of the clamping lug.

Description

B e s c h r e i b u n g Description
Vorrichtung zum Befestigen von plattenförmigen FassadenelementenDevice for fastening plate-shaped facade elements
Die Erfindung betrifft eine Vorrichtung zum Befestigen von plattenförmigen Fassadenelementen an einem Baukörper durch Befestigungsteile, die einerseits am Baukörper und ande¬ rerseits an den Fassadenelementen angreifen, wobei die Fassadenelemente an zwei einander gegenüberliegenden Kan¬ ten einen zum Baukörper hin umgebogenen Rand und an diesem Rand einen einwärts gerichteten Flansch aufweisen und die Befestigungsteile aus am Baukörper in gegenseitigen Ab¬ ständen befestigten U-förmigen Halteprofilen mit zwei vom Baukörper abstehenden Schenkeln sowie aus zwischen diesen Schenkeln aufnehmbaren Profilstäben bestehen, die wenig¬ stens zwei Halteprofile überbrücken und in wählbaren Ab¬ ständen vom Baukörper mit den Halteprofilen fest verbind¬ bar sind.The invention relates to a device for fastening plate-shaped facade elements to a building structure by means of fastening parts which engage on the one hand on the building body and on the other hand on the facade elements, the facade elements on two opposite edges having a bent edge towards the building body and one on this edge have inward-facing flange and the fastening parts consist of U-shaped holding profiles fastened to the building structure at mutual distances with two legs projecting from the building body and of profile bars which can be received between these legs and which bridge at least two holding profiles and at selectable distances from the building body can be firmly connected to the holding profiles.
Bei bekannten Vorrichtungen dieser Art sind die Befesti¬ gungsteile zwischen Baukörper und Fassadenelement wegen des kleinen, zur Verfügung stehenden Raumes nur unter Schwierigkeiten zu handhaben und gestatten insbesondere keine saubere Ausrichtung der Fassadenelemente unter Aus¬ bildung gleichmäßiger Fugen zwischen den Elementen. Außer¬ dem mußten bisher Befestigungsteile am Rand der Fassaden¬ elemente angebracht werden, die Bohrungen oder Schlitze am Rand durchdrangen. Hier steht besonders wenig Raum zur Verfügung, vor allem aber bieten diese Bohrungen und Schlitze Ansatzstellen für Korrosion.In known devices of this type, the fastening parts between the structure and the facade element are difficult to handle because of the small space available, and in particular do not allow a clean alignment of the facade elements with the formation of uniform joints between the elements. In addition, previously fastening parts had to be attached to the edge of the facade elements, which penetrated holes or slots on the edge. There is particularly little space available here, but above all these bores and slots offer starting points for corrosion.
Es ist Aufgabe der Erfindung, eine gattungsgemäße Vorrich¬ tung so weiterzubilden, daß die Fassadenelemente in gegen- seitiger präziser Ausrichtung leicht und bequem am Bau¬ körper befestigt werden können und dabei keine Korrosions¬ gefahr entsteht.It is an object of the invention to develop a generic device such that the facade elements in opposite side precise alignment can be easily and conveniently attached to the structure and there is no risk of corrosion.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Profilstäbe im Querschnitt hutförmig sind und seitlich abstehende, parallel zu den Flanschen der Fassa¬ denelemente verlaufende Stege aufweisen, daß Spannpratzen vorgesehen sind mit einer Gewindebohrung und mit einem Maul, wobei das Maul jeweils gemeinsam einen Steg des Profilstabes und einen Flansch des Fassadenelementes um¬ schließt, und daß am Profilstab Spannbolzen mit Außengewinde drehbar und axial unverschieblich gelagert sind, welche jeweils die Gewindebohrung einer Spannpratze durchdringen und bei ihrer Verdrehung eine Bewegung der Spannpratze relativ zum Steg und Flansch bewirken, so daß diese im Maul der Spann¬ pratze verspannbar sind.The object is achieved in that the profile bars are hat-shaped in cross-section and have laterally projecting webs which run parallel to the flanges of the facade elements, that clamping claws are provided with a threaded bore and with a jaw, the jaws each together having a web of the Closes profile bar and a flange of the facade element, and that clamping bars with external threads are rotatably and axially immovably mounted on the profile bar, which penetrate the threaded bore of a clamping claw and, when they are rotated, cause a movement of the clamping claw relative to the web and flange, so that they act in the Mouth of the clamping claw can be clamped.

Es zeigen:The following description of a preferred embodiment of the invention serves in conjunction with the accompanying drawing for further explanation. Show it:

Fig. 6 eine Ansicht ähnlich Fig. 5 mit einer abgewandelten Ausführungsform der Fassa¬ denelemente.FIG. 6 is a view similar to FIG. 5 with a modified embodiment of the facade elements.
Die Fig. 1 zeigt eine Gebäudefassade aus mehreren neben¬ einander angeordneten, jeweils gleich ausgebildeten plat¬ tenförmigen Fassadenelementen 1, z.B. in Form emaillierter Blechtafeln, wobei zwischen den einzelnen Elementen 1 je¬ weils Schattenfugen ausgebildet sind. Die Fassadenelemente 1 sind - vgl. Fig. 2 und 3 - mit Hilfe von noch zu be¬ schreibenden Befestigungsteilen vertikal an einem Baukör¬ per 2 angeordnet. Die Befestigungsteile greifen dabei in ebenfalls noch zu erläuternder Weise einerseits am Bau¬ körper 2 und andererseits an den Fassadenelementen 1 an. Die Fassadenelemente weisen - vgl. insbesondere Fig. 3 - an zwei einander gegenüberliegenden, gewöhnlich senkrecht verlaufenden Kanten einen zum Baukörper 2 hin umgebogenen Rand 3 und an diesem Rand einen einwärts gerichteten Flansch oder Bördel 4 auf. Am Baukörper 2 sind in gegenseitigen Abständen U-förmige Halteprofile 5 mit zwei vom Baukörper 2 weg gerichteten, abstehenden Schenkeln 6 befestigt (vgl. insbesondere Fig. 3). Die Befestigung erfolgt mit Hilfe von Schrauben 7 und Unterlegscheiben 8, wobei die Schrauben ein (bei der dargestellten Ausführungsform horizontal verlaufendes) Langloch 9 durchdringen und in einen im Baukörper 2 be¬ festigten Dübel 11 eingedreht sind. Das Langloch 9 er¬ möglicht eine seitliche Ausrichtung der Halteprofile 5 am Baukörper 2. Bei der dargestellten Ausführungsform erfolgt diese Ausrichtung in horizontaler Richtung. An den Schen¬ keln 6 der Halteprofile sind weitere Langlöcher 12 aus¬ gebildet.1 shows a building facade consisting of a plurality of plate-shaped facade elements 1 arranged next to one another and each of the same design, for example in the form of enamelled metal sheets, shadow gaps being formed between the individual elements 1. The facade elements 1 are - cf. 2 and 3 - arranged vertically on a structure 2 with the aid of fastening parts to be described. The fastening parts act on the structure 2 on the one hand and on the facade elements 1 on the other hand in a manner which is also yet to be explained. The facade elements point - cf. in particular Fig. 3 - on two opposite, usually perpendicular edges, an edge 3 bent towards the building body 2 and on this edge an inward flange or flange 4. U-shaped holding profiles 5 are attached to the structure 2 at mutual intervals with two projecting legs 6 directed away from the structure 2 (cf. in particular FIG. 3). The fastening is carried out with the aid of screws 7 and washers 8, the screws penetrating an elongated hole 9 (which runs horizontally in the embodiment shown) and are screwed into a dowel 11 fastened in the structure 2. The elongated hole 9 enables the holding profiles 5 to be aligned laterally on the structure 2. In the embodiment shown, this alignment takes place in the horizontal direction. Further elongated holes 12 are formed on the legs 6 of the holding profiles.
Die Halteprofile 5 nehmen zwischen ihren Schenkeln 6 im Querschnitt hutförmig gestaltete Profilstäbe 13 auf, die mehrere, mindestens aber zwei Halteprofile 5 überbrücken. Die Profilstäbe 13 weisen zwei seitlich von einem U-förmi- gen Mittelteil abstehende Stege 14 auf, die parallel zu den Bördeln 4 der Fassadenelemente 1 verlaufen. Die Pro¬ filstäbe 13 sind mit Hilfe von Schrauben 15, welche die Langlöcher 12 an den Schenkeln 6 der Halteprofile durch¬ dringen, in wählbaren Abständen vom Baukörper 2 mit den Halteprofilen 5 fest verbunden. Zwischen die Profilstäbe 13 und die jeweils benachbarten Schenkel 6 der Haltepro¬ file 5 sind Distanzstücke 16 eingefügt. Diese Distanz¬ stücke 16 sind, wie aus Fig. 3 ersichtlich, beidseits mit Zahnungen versehen, die in entsprechende Zahnungen an der Innenseite der Schenkel 6 bzw. an der Außenseite der Pro¬ filstäbe 13 eingreifen. Auf diese Weise kann vor dem Fest¬ ziehen einer auf der Schraube 15 befindlichen Mutter 17 der Abstand eines Profilstabes 13 vom Baukörper 2 ent- sprechend eingestellt werden. Nach dem Anziehen der Mutter greifen die erwähnten Zahnungen ineinander und halten den Profilstab in dem gewählten Abstand vom Baukörper, so daß von den Fassadenelementen 1 ausgehende Sog- und Druckbe¬ lastungen in den Baukörper 2 übertragbar sind.The holding profiles 5 receive between their legs 6 in cross-section hat-shaped profile bars 13 which bridge several, but at least two holding profiles 5. The profile bars 13 have two webs 14 projecting laterally from a U-shaped central part, which run parallel to the flanges 4 of the facade elements 1. The profile rods 13 are fixedly connected to the holding profiles 5 at selectable distances from the structure 2 by means of screws 15 which penetrate the elongated holes 12 on the legs 6 of the holding profiles. Spacers 16 are inserted between the profile bars 13 and the respectively adjacent legs 6 of the holding profile 5. As can be seen from FIG. 3, these spacers 16 are provided on both sides with serrations which engage in corresponding serrations on the inside of the legs 6 or on the outside of the profile rods 13. In this way, before a nut 17 located on the screw 15 is tightened, the distance of a profiled rod 13 from the structure 2 can be determined. be set accordingly. After tightening the nut, the teeth mentioned interlock and hold the profile bar at the selected distance from the structure, so that suction and pressure loads originating from the facade elements 1 can be transmitted into the structure 2.
Zwischen den der Befestigung der Profilstäbe 13 am Baukör¬ per 2 dienenden Halteprofile sind - vgl. Fig. 1 - Spann¬ pratzen 18 vorgesehen, deren Aufbau und Wirkungsweise im einzelnen anhand von Fig. 4 und 5 erläutert wird. Die Spannpratzen 18, die - abgesehen vom Rand der Fassade - normalerweise einander paarweise gegenüberliegen, umfassen in einem Schenkel 19 eine Gewindebohrung 21 sowie ein von zwei Backen 22, 23 gebildetes Maul 24. Wie aus Fig. 5 er¬ sichtlich, umschließt im fertig montierten Zustand das Maul 24 klemmend jeweils gemeinsam einen Steg 14 des Pro¬ filstabes 13 und einen Bördel 4 eines Fassadenelementes 1, so daß hierdurch zwei benachbarte Fassadenelemente 1 unter Ausbildung einer Schattenfuge 25 fest mit dem Profilstab 13 und damit mit dem Baukörper 2 verbunden sind, weil der Profilstab 13, wie bereits erläutert, über die Haltepro¬ file 5 am Baukörper 2 befestigt ist.Between the fastening profiles serving to fasten the profile bars 13 to the structure 2 there are - cf. 1 - clamping claws 18 are provided, the structure and mode of operation of which are explained in detail with reference to FIGS. 4 and 5. The clamping claws 18, which - apart from the edge of the facade - normally lie opposite one another in pairs, comprise a threaded bore 21 in a leg 19 and a mouth 24 formed by two jaws 22, 23. As can be seen from FIG Condition the jaw 24 clamped together a web 14 of the profile bar 13 and a flange 4 of a facade element 1, so that two adjacent facade elements 1 are thereby firmly connected to the profile bar 13 and thus to the structure 2, forming a shadow gap 25, because the profile rod 13, as already explained, is attached to the structure 2 via the holding profile 5.
Wie ebenfalls aus Fig. 5 hervorgeht, sind in jeweils zwei einander gegenüberliegenden Bohrungen 26 des Profilstabes 13 Spannbolzen 27 drehbar gelagert. Jeder Spannbolzen 27 weist zwei Bolzenabschnitte 28, 29 auf, die mit gegenläu¬ figen Außengewinden versehen sind. Diese Bolzenabschnitte 28, 29 durchdringen die glatten Bohrungen 26 frei drehbar. Der Spannbolzen 27 umfaßt ein Mittelteil 31 , das zum An¬ legen eines Verdrehwerkzeuges einen polygonalen, z.B. sechseckigen Querschnitt aufweist. Von dem Mittelteil 31 stehen die mit ihm fest verbundenen Bolzenabschnitte 28, 29 ab. Der Mittelteil 31 ist so bemessen, daß er frei drehbar und axial unverschieblich genau in das U-förmige Mittelteil des Profilstabes 13 hineinpaßt, wobei er mit seinen beiden einander gegenüberliegenden Stirnseiten an den Schenkeln des U-Profils anliegt. Auf diese Weise ist auch der gesamte Spannbolzen 27 axial unverschieblich, je¬ doch drehbar mit dem Profilstab 13 verbunden.As can also be seen from FIG. 5, 13 clamping bolts 27 are rotatably mounted in two mutually opposite bores 26 of the profiled rod. Each clamping bolt 27 has two bolt sections 28, 29 which are provided with opposing external threads. These bolt sections 28, 29 penetrate the smooth bores 26 in a freely rotatable manner. The clamping bolt 27 comprises a central part 31, which has a polygonal, for example hexagonal cross-section for applying a twisting tool. From the middle part 31 are the bolt sections 28, 29 firmly connected to it. The central part 31 is dimensioned such that it fits freely in the U-shaped central part of the profiled rod 13 so as to be freely rotatable and axially immovable, with its two opposite end faces resting against the legs of the U-profile. In this way, the entire clamping bolt 27 is axially immovable, but rotatably connected to the profile bar 13.
Die beiden Bolzenabschnitte 28, 29 des Spannbolzens 27 durchdringen jeweils die Gewindebohrungen 21 an den Schen¬ keln 19 der zwei einander gegenüberliegenden Spannpratzen 18. Wegen der gegenläufigen Außengewinde an den Bolzenab¬ schnitten 28 und 29 erfolgt somit bei einer Verdrehung des Spannbolzens 27 eine aufeinander zugerichtete Bewegung der Spannpratzen 18, wobei diese Bewegung eine Verschiebung der Spannpratzen 18 relativ zum Steg 14 des Profilstabes 13 und zum an diesen Steg angelegten Bördel 4 des Fassa¬ denelements 1 bewirkt, so daß diese Teile (Steg 14 und Bördel 4) gemeinsam im Maul 24 jeder Spannpratze 18 ver¬ spannbar sind.The two bolt sections 28, 29 of the clamping bolt 27 each penetrate the threaded bores 21 on the legs 19 of the two mutually opposite clamping claws 18. Because of the opposing external threads on the bolt sections 28 and 29, a rotation of the clamping bolt 27 thus leads to a facing one another Movement of the clamping claws 18, this movement causing a displacement of the clamping claws 18 relative to the web 14 of the profiled rod 13 and to the flange 4 of the facade element 1 applied to this web, so that these parts (web 14 and flange 4) together in the mouth 24 each claw 18 can be clamped.
Um den Spannbolzen 27 so am Profilstab 13 anzuordnen, daß er mit seinem Mittelteil 31 axial unverschieblich zwischen den Schenkeln dieses Profilstabes 13 gehalten ist, wird beispielsweise der Mittelteil 31 für sich in das U-förmige Mittelteil des Profilstabes 13 eingesetzt. Anschließend werden von beiden Seiten her die Bolzenabschnitte 28, 29 in den Mittelteil 31 eingeschraubt, wobei Schlitze an den freien Stirnseiten der Bolzenabschnitte 28, 29 der Auf¬ nahme eines Drehwerkzeuges, z.B. eines üblichen Schrauben¬ drehers dienen. Die beiden Bolzenabschnitte 28, 29 werden soweit in den Mittelteil 31 hineingeschraubt, daß sie mit ihren Stirnseiten im Mittelteil 31 aneinander anliegen, sich hierdurch gegenseitig kontern und einen festen Sitz im Mittelteil 31 erhalten. Man kann alternativ hierzu auch die Bohrungen 26, welche den Spannbolzen 27 drehbar auf¬ nehmen, im Profil - z.B. schlüssellochartig - so gestal¬ ten, daß in einem oberen, relativ weiten Bereich der Mit¬ telteil 31 hindurchgesteckt werden kann, woraufhin der Spannbolzen in einen entsprechend engen Teil der Öffnung abgesenkt wird, dessen Breite dem Durchmesser der Bohrung 26 entspricht.In order to arrange the clamping bolt 27 on the profile bar 13 so that it is held axially immovably between the legs of this profile bar 13 with its central part 31, the central part 31 is used for example in the U-shaped central part of the profile bar 13. The bolt sections 28, 29 are then screwed into the middle part 31 from both sides, slots on the free end faces of the bolt sections 28, 29 serving to receive a turning tool, for example a conventional screwdriver. The two bolt sections 28, 29 are so far screwed into the middle part 31 that they abut with their end faces in the middle part 31, thereby countering each other and get a firm fit in the middle part 31. As an alternative to this, the bores 26, which receive the clamping bolt 27 rotatably, can be designed in profile - for example, like a keyhole - in such a way that the middle part 31 can be inserted in an upper, relatively wide area, whereupon the clamping bolt in a correspondingly narrow part of the opening is lowered, the width of which corresponds to the diameter of the bore 26.
Die Fig. 4 zeigt den Zustand der Spannpratzen 18 vor der Montage der Fassadenelemente 1. Die beiden Spannpratzen 18 haben (gegenüber Fig. 5) noch einen relativ großen gegen¬ seitigen Abstand, so daß die Bördel 4 zweier benachbarter Fassadenelemente 1 an die jeweiligen Stege 14 des Profil¬ stabes angelegt werden können. Dabei kann zwischen Bördel 4 und Steg 14 auch eine vorzugsweise elastische Dichtung 32 eingelegt werden, die sich im übrigen über die gesamte (vertikale) Längserstreckung des Bördeis 4 erstrecken kann. Die beiden Fassadenelemente 1 werden so an den Stegen 14 des Profilstabes 13 festgehalten, daß sich zwischen ihnen die Schattenfuge 25 ausbildet. Anschließend wird durch diese Fuge hindurch ein Verdrehwerkzeug am Mit¬ telteil 31 des Spannbolzen 27, z.B. ein Schraubenschlüs¬ sel, angesetzt und dt-_r Spannbolzen verdreht. Wegen der gegenläufigen Gewinde an den Bolzenabschnitten 28, 29 be¬ wegen sich dabei die Spannpratzen 18 aufeinander zu, er¬ fassen in ihrem Maul 24 jeweils einen Bördel 4 und einen Steg 14 und verspannen diese im Maul. Es ist günstig, zu diesem Zweck die Querschnittsform des Maules 24 so auszu- bilden, daß es sich nach innen keilförmig verjüngt. Gün¬ stig ist es auch, die Öffnung des Maules 24 an wenigstens einer Randkante anzufasen, wie in Fig. 4 und 5 durch das Bezugszeichen 33 angedeutet. Hierdurch wird das Eindringen des Bördeis 4 und des Steges 14 in das Maul 24 (vgl. Fig. 4) erleichtert. Im übrigen unterstützt auch die Elastizi¬ tät der Dichtung 32 die Verklemmung der Teile 4 und 14 im Maul 24.FIG. 4 shows the state of the clamping claws 18 before the facade elements 1 are installed. The two clamping claws 18 (compared to FIG. 5) are still at a relatively large mutual distance, so that the flanges 4 of two adjacent facade elements 1 on the respective webs 14 of the profile rod can be created. In this case, a preferably elastic seal 32 can also be inserted between the flange 4 and the web 14, which can also extend over the entire (vertical) longitudinal extent of the Bördeis 4. The two facade elements 1 are held on the webs 14 of the profile rod 13 in such a way that the shadow gap 25 is formed between them. Subsequently, a twisting tool, for example a wrench, is attached to the central part 31 of the clamping bolt 27 through this joint and the clamping bolt is rotated. Because of the opposing threads on the bolt sections 28, 29, the clamping claws 18 move towards one another, grasp a flange 4 and a web 14 in their mouth 24 and clamp them in the mouth. For this purpose, it is expedient to design the cross-sectional shape of the mouth 24 in this way. form that it tapers inwards in a wedge shape. It is also advantageous to chamfer the opening of the mouth 24 on at least one edge, as indicated in FIGS. 4 and 5 by the reference number 33. This facilitates the penetration of the Bördeis 4 and the web 14 into the mouth 24 (see. Fig. 4). Moreover, the elasticity of the seal 32 also supports the jamming of the parts 4 and 14 in the mouth 24.
Die Verspannung des Bördeis 4 im Maul 24 läßt sich weiter¬ hin erleichtern und verbessern, wenn der Winkel α (Fig. 4) zwischen Rand 3 und Steg 14 des Fassadenelements 1 etwas größer als 90°, beispielsweise etwa 92° beträgt.The bracing of the Bördeis 4 in the mouth 24 can be further facilitated and improved if the angle α (FIG. 4) between the edge 3 and the web 14 of the facade element 1 is somewhat greater than 90 °, for example approximately 92 °.
Auf diese Weise lassen sich die Fassadenelemente 1 zuein¬ ander genau ausgerichtet, in einfacher Weise am Baukörper 2 befestigen. Aufgrund der Verspannung der Bördel 4 in den Spannpratzen 18 entfallen Bohrungen oder Schlitze in den Rändern 3, wie sie bisher zur Halterung der Fassadenele¬ mente 1 am Baukörper 2 erforderlich waren. Hierdurch sind erfindungsgemäß die mit diesen Bohrungen und Schlitzen gekoppelten Korrosions- und Rostansatzstellen vermieden.In this way, the facade elements 1 can be precisely aligned with one another and fastened to the structure 2 in a simple manner. Due to the bracing of the flanges 4 in the clamping claws 18, there are no holes or slots in the edges 3, as were previously required for holding the facade elements 1 on the structure 2. In this way, according to the invention, the corrosion and rust spots which are coupled with these bores and slots are avoided.
Um bei der dargestellten Ausführungsform die Fassadenele¬ mente 1 zusätzlich an einem Verrutschen nach unten zu hindern - soweit hierzu nicht bereits die Verspannung der Fassadenelemente in den Spannpratzen 18 ausreicht -, weisen die Fassadenelemente 1 an wenigstens einer Kante, im dargestellten Ausführungsbeispiel an der Oberkante, quer zu den einwärts gerichteten Bördeln 4 der Elemente 1 verlaufend einen nach auswärts gerichteten Umschlag 34 auf, der durch Schrauben 35 mit Muttern 36 an den Stegen 14 des Profilstabes 13 festgelegt wird (Fig. 1 und 2). Die Fig. 6 zeigt eine gegenüber Fig. 5 abgewandelte Aus¬ führungsform. Im Gegensatz zu Fig. 5 sind in Fig. 6 die Bördel 4 schmäler ausgebildet. Hierdurch wird die Schat¬ tenfuge 25 in Fig. 6 breiter als in Fig. 5. In order to additionally prevent the facade elements 1 from slipping downward in the embodiment shown - provided that the tensioning of the facade elements in the clamping claws 18 is not sufficient for this purpose - the facade elements 1 have at least one edge, in the exemplary embodiment shown on the upper edge, running transversely to the inwardly directed flanges 4 of the elements 1, an outwardly directed envelope 34, which is fixed by screws 35 with nuts 36 to the webs 14 of the profiled rod 13 (FIGS. 1 and 2). FIG. 6 shows an embodiment modified from FIG. 5. In contrast to Fig. 5, the flanges 4 are formed narrower in Fig. 6. As a result, the shadow gap 25 in FIG. 6 becomes wider than in FIG. 5.
