Description

Die Erfindung betrifft eine in Betonträger oder dergleichen einbettbare Schiene gemäß Oberbegriff der Ansprüche 1 und 2.The invention relates to a concrete beam or the like embeddable rail according to the preamble of Claims 1 and 2.

Ankerschienen der in Rede stehenden Art sind bekannt aus der DE-U-7 524 212, wobei die Anker- von der Seite her gesehen, einen rechteckigen Grundriß besitzen. Die Belastungsstabilität einer solchen Ausgestaltung ist oftmals unzureichend, wenn Belastungen in Schienen-Längsrichtung auftreten. Derartige Beanspruchungen erhält man z.B., wenn Dachflächen unter anderem zur Gehäuseaussteifung als Scheiben ausgebildet werden. Aufgrund der hohen Belastungen können Verformungen an der Schiene und der an diese angesetzten Endabschnitte der Anker auftreten. Diese Verformung ist aufgrund der flachstabähnlich gestalteten Anker möglich, da sie nur die Einbettung der Schiene stabilisieren, nicht aber die Schiene selbst. Sind solche Befestigungsschienen zur Halterung von Fassaden herbeigezogen, so können die erheblich belasteten Befestigungsschienen noch hohen Temperaturschwankungen unterliegen, was ebenfalls zu gewissen Verformungen der Befestigungsschiene führt.Anchor channels of the type in question are known from DE-U-7 524 212, the anchor from the side seen here, have a rectangular plan. The Load stability of such a configuration is often inadequate when loads are in the longitudinal direction of the rails occur. Such strains can be obtained, for example, if roof areas are used for Housing stiffeners are designed as disks. Due to the high loads, deformations can occur the rail and the end sections attached to it the anchor occur. This deformation is due to the Flat bar-like anchors possible because they only stabilize the embedding of the rail, but not the rail itself. Are such fastening rails used to hold facades, so the mounting rails still heavily loaded Temperature fluctuations are subject to what too certain deformations of the mounting rail.

Aus der US-A-1 499 983 ist es bekannt, die Schiene als Holzleiste zu gestalten und mittels Anker an einem Boden abzustützen. Die Anker sind im Wege eines Festklemmens mit der Holzleiste verbunden. In Querrichtung der Holzleiste gesehen, besitzen die Anker eine V-Form, wobei der Scheitel dieses V-Profils der Holzleiste zugekehrt ist.From US-A-1 499 983 it is known to use the rail Wood bar to design and anchor to one Support the ground. The anchors are clamped connected to the wooden bar. In the transverse direction seen on the wooden strip, the anchors have a V-shape, the vertex of this V-profile of the wooden strip turned towards.

Sodann ist es aus der DE-A-2 712 808 bekannt, anstelle einer Schiene zwei Armierungsstäbe in paraller Nebeneinanderlage vorzusehen, welche gemäß Figur 3 dieser Schrift von den horizontal verlaufenden Verbindungsbrükken von Bügeln untergriffen sind. Im Bereich dieser geradlinigen Abschnitte sind die Bügel an den Armierungsstäben angeschweißt. Es genügt, lediglich die beiden äußersten geradlinigen Abschnitte mit den Armierungsstäben zu verschweißen. Die die Bügel verbindenden Querstege erlauben keine Längsverschiebung einer Ankerschraube.Then it is known from DE-A-2 712 808 instead one reinforcement bar in parallel side by side to provide which according to Figure 3 this Writing from the horizontal connecting bridges are undermined by hangers. In the area of this straight sections are the brackets on the reinforcing bars welded on. It is enough just that two outermost straight sections with the reinforcing bars to weld. The connecting the brackets Cross bars do not allow the longitudinal displacement of an anchor bolt.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Schiene bei einfachem Aufbau so auszugestalten, daß trotz Anordnung einer Weichstoffschicht eine geringe Verformung der Schiene bei hohen Belastungen verwirklicht ist.The invention has for its object a generic To design the rail with a simple structure, that despite the arrangement of a layer of soft material, a slight Deformation of the rail realized under high loads is.

Dieses technische Problem ist jeweils durch die Merkmale der beiden Ansprüche 1 und 2 gelöst.This technical problem is due to the characteristics of both Claims 1 and 2 solved.

Die abhängigen Ansprüche stellen vorteilhafte Weiterbildungen der erfindungsgemäßen Lösung dar.The dependent claims represent advantageous developments the solution according to the invention.

Zufolge derartiger Ausgestaltung ist eine in Betonträger oder dergleichen einbettbare Schiene zur Ableitung von Kräften beispielsweise zur Halterung von insbesondere Fassaden-Verkleidungselementen von erhöhtem Gebrauchswert angegeben. Mit Vorteil läßt sich ein Ankerabstand von z.B. 150 mm vorsehen. Dieser geringe Ankerabstand gestattet auch beim bauseitigen Ablängen von Fixmaßen stets eine einwandfreie Verankerung der Schiene, ohne daß besondere Zusatzmaßnahmen vorgenommen werden müßten. Ferner ist ein solcher geringer Abstand von 150 mm auch hinsichtlich der in den Betonteilen angeordneten Bügelbewehrung zweckmäßig, um ein möglichst behinderungsfreies Einlegen der Schienen zu gewährleisten. Häufig bzw. in der Regel werden Bügelbewehrungen ebenfalls im Abstand von 150 mm angeordnet, so daß die Möglichkeit besteht, die an der Schiene sitzenden Anker jeweils zwischen den Bewehrungsbügeln anzuordnen. Sodann eignet sich die erfindungsgemäße Ausgestaltung auch besonders zur Ableitung von Belastungen in Schienenlängsrichtung zufolge der in Beanspruchungsrichtung vorliegenden ausreichenden Steifigkeit. Aufgrund der V-förmigen Ausgestaltung der Anker und deren Schweiß-Befestigungsstellen an der Schiene wird dieselbe selbst bei Vorsehen der das Eindrehen von Schrauben erlaubenden Schicht zur Schaffung des betonfreien Raumes stabilisiert. Was die Schicht der Schiene an Stabilität nimmt, wird dieser wieder durch die Gestaltung und Festlegung der Anker an der Schiene zugeführt. Die V-förmige Ausgestaltung der Anker verteilt die an jedem Anker wirksam werdenden Belastungen auf zwei in Schienenlängsrichtung hintereinanderliegende Punkte, und zwar über das zur Schiene hin offene V-Profil, wodurch die Schiene erheblich versteift wird, verbunden mit dem Vorteil einer hohen Stabilität. Entsprechend den aufzunehmenden Belastungen kann der Anker eine unterschiedliche Bügelform besitzen. Neben einer V-Form ist auch ein wellenförmiger Verlauf möglich, und zwar dadurch daß die Ankerbügel von einem in entsprechender Wellenform durchlaufenden und mehrere Anker hintereinanderliegend aufweisenden gebogenen Stab gebildet sind. Durch Einsatz von Rundstahl für die Ankerbügel ist auch eine Verletzungsgefahr erheblich vermindert, da keine vorstehenden, scharfkantigen Ecken vorhanden sind. Die Oberfläche des Rundstahles kann zur verbesserten Einbettung noch profiliert sein. Es läßt sich eine solche Wellenform bei der Biegung des Rundstahles verwirklichen, daß zwischen zwei Ankerausbiegungen sich ein in Schienenlängsrichtung verlaufender geradliniger Zwischenabschnitt erstreckt. Auf diese Weise können die Anker besonders fest der Schiene zugeordnet werden. Zur Stabilisierung der hintereinanderliegenden Anker und zur Erzielung einer höheren Tragfähigkeit ist ein parallel zur Schiene und im Abstand zu dieser die Bügelschenkel etwa auf mittlerer Länge verbindender Versteifungsdraht einsetzbar. Mit Vorteil kann die Schiene als Befestigungsschiene mit U-förmigem Querschnitt gestaltet sein. Deren U-Innenraum kann die Weichstoffschicht vollständig ausfüllen. Die entsprechende Füllung kann kontinuierlich eingeschäumt werden, und zwar mittels einer Durchlauf-Füllanlage. Gesondert vorgefertigte rechteckige Streifenelemente können demgemäß entfallen. Da der Schienenrücken einer solchen Befestigungsschiene oberflächenbündig mit dem Betonträger abschließt, werden die Anker bevorzugt an den U-Schenkeln festgelegt, so daß sie diese überragen und daher in dem Betonträger eingebettet sind. Möglich ist es jedoch auch, die Befestigungsschiene in Form eines Flachstreifens zu gestalten, welcher randseitig mit den V-förmigen Ankern bestückt wird. Der Einsatz eines Flachstreifens als Befestigungsschiene ist möglich wegen des geringen Ankerabstandes, so daß das Profil der Befestigungsschiene selbst keine hohe Eigensteifigkeit mehr aufweisen muß. In dem Bereich zwischen den Ankern wird an der Unterseite des Flachstreifens die Weichstoffschicht - beispielsweise ein Schaumstoffstreifen - festgelegt. Ebenfalls wäre Holz als Weichstoffschicht denkbar. Ferner könnten auch Hohlkörper oder Verbundkörper eingesetzt werden. Die Befestigung der Schicht kann beispielsweise durch Klebung erfolgen. Weiterhin läßt sich die Schiene als Ankerschiene mit C-förmigem Querschnitt gestalten. In diesem Fall werden die Anker an den zum Schienenrücken rechtwinklig verlaufenden Schienenseitenwänden derart festgelegt, daß sie den Schienenrücken überragen. Der von dem C-Profil gebildete Längsschlitz der Schiene schließt nach dem Einbetonieren derselben bündig mit der entsprechenden Betonkonstruktion ab, während die Anker in diese hineinragen und dort zu einer festen Einbettung der Ankerschiene beitragen. Vor dem Einbetonieren wird der Schieneninnenraum mit einer Weichstoffschicht ausgefüllt, die zum Zwecke des Einsetzens der Hammerkopf-Schrauben herauszunehmen ist. Bei einer im Querschnitt-U-profilierten Befestigungsschiene können für einen festen Sitz der Weichstoffschicht entsprechende Hinterschneidungen der U-Schenkel sorgen. Durch die Hinterscheidungen werden auch punktförmige Schweißbefestigungsstellen für die Anker geschaffen. Die Hinterschneidungen können so gestaltet sein, daß die zum freien Ende der Befestigungssschiene divergierend verlaufenden Teilabschnitte der U-Schenkel die Anschweißflächen für in divergierenden Ebenen zur Befestigungsschiene liegenden Anker bilden. Alternativ ist es jedoch auch möglich, die Anker vor die den Schienen-Längsseitenrand bildende Stirnfläche der U-Schenkel der Befestigungsschiene zu setzen und dort durch Schweißen zu haltern. Ferner können die bügelförmigen Anker eine zur Schienenlängsmittelebene gerichtete Abbiegung aufweisen, die das Einfädeln der Anker zwischen dichte Bewehrungslagen erleichtern. An die Abbiegung schließt sich bei einer Weiterbildung eine gegensinnige Abbildung an unter Bildung eines Z-Verlaufes des Ankers, im Querschnitt der Schiene betrachtet. Optimiert wird das Einfädeln zwischen dichte Bewehrungslagen dadurch, daß bei gegenüberliegend angeordneten Ankern die Abbiegungen so angeordnet sind, daß zumindest die Scheitelabschnitte der Anker ineinandergeschachtelt sind. As a result of such a configuration, one is in a concrete beam or similar embeddable rail for derivation of forces, for example, for holding in particular Facade cladding elements of increased use value specified. An anchor spacing can be used with advantage from e.g. Provide 150 mm. This small anchor spacing also permitted when cutting to length by the customer Fixed dimensions always a perfect anchorage of the rail, without special additional measures should be. Furthermore, such a small distance of 150 mm also with regard to that in the concrete parts arranged stirrup reinforcement expedient to a possible unobstructed insertion of the rails guarantee. Armor reinforcements are common, or usually also arranged at a distance of 150 mm, so that there is the possibility of being on the rail anchors sitting between the reinforcement brackets to arrange. Then the invention is suitable Design especially for the derivation of loads in the longitudinal direction of the rail according to the direction of stress present sufficient rigidity. Due to the V-shaped design of the anchor and whose welding attachment points on the rail the same even if the screwing in is provided Screw-permeable layer to create the concrete-free Stabilized space. As for the layer of the rail takes on stability, this is again due to the design and fix the anchor on the rail fed. The V-shaped design of the anchor is distributed the loads acting on each anchor two lying one behind the other in the longitudinal direction of the rail Points, namely via the V-profile open towards the rail, which significantly stiffens the rail, combined with the advantage of high stability. Corresponding The anchor can support the loads to be absorbed have a different bow shape. In addition to one V-shape, a wavy course is also possible, and in that the anchor bracket from one in a corresponding Continuous waveform and multiple anchors consecutive curved rod formed are. By using round steel for the anchor bracket the risk of injury is also significantly reduced, because there are no protruding, sharp-edged corners are. The surface of the round steel can be used improved embedding can still be profiled. It leaves such a waveform when bending the round steel realize that between two anchor deflections a running in the longitudinal direction of the rail straight intermediate section extends. To this In this way, the anchors can be assigned to the rail particularly firmly will. To stabilize the one behind the other Anchors and to achieve a higher load capacity is a parallel to and at a distance from the rail this connecting the stirrup legs approximately on a medium length Stiffening wire can be used. With advantage can the rail as a mounting rail with a U-shaped Cross section be designed. Their U interior can Fill in the soft layer completely. The corresponding Filling can be foamed continuously, by means of a continuous filling system. Separately Prefabricated rectangular stripe elements can accordingly eliminated. Because the rail back of such Mounting rail flush with the concrete beam completes, the anchors are preferred on the U-legs set so that they tower above and are therefore embedded in the concrete beam. Is possible it also, however, the mounting rail in the form of a To design flat strip, which edge with the V-shaped anchors. The use of a Flat strip as a fastening rail is possible because of the small anchor spacing, so that the profile the mounting rail itself does not have a high level of rigidity must have more. In the area between the Anchoring is carried out on the underside of the flat strip Soft material layer - for example a foam strip - fixed. Wood would also be a layer of soft material conceivable. Furthermore, hollow bodies or Composite bodies are used. The attachment of the Layer can be done for example by gluing. Furthermore, the rail can be used as an anchor rail Design a C-shaped cross-section. In this case the anchors to those that are perpendicular to the back of the rail Rail side walls set such that they protrude the rail back. The one from the C profile formed longitudinal slot of the rail closes after the Concrete them flush with the corresponding one Concrete structure, while the anchors protrude into it and there for a permanent embedding of the anchor channel contribute. Before concreting in, the interior of the rail filled with a layer of soft material, for the purpose of inserting the hammer head screws is to be taken out. With a U-shaped cross-section Fixing rails can be used for a fixed Undercuts corresponding to the soft material layer the U-leg worry. Through the undercuts are also point-like welding attachment points created for the anchor. The undercuts can be designed so that the free end of the mounting rail divergent sections the U-leg the welding surfaces for in diverging Form levels to the anchor rail. Alternatively, however, it is also possible to use the anchors in front of the end face forming the longitudinal edge of the rail to put the U-leg of the mounting rail and hold there by welding. Furthermore, the bow-shaped anchor one to the longitudinal plane of the rail have directed turn that threading the Lighten anchor between dense reinforcement layers. On the turn closes with further training an opposite figure to form a Z-shape of the anchor, in the cross section of the rail considered. The threading between dense is optimized Reinforcement layers in that at opposite arranged anchors the bends are arranged so that at least the vertices of the anchors are nested are.

Gemäß dem ersten Ausführungsbeispiel, dargestellt in den Figuren 1 bis 4, handelt es sich bezüglich der Schiene 1 um eine im Querschnitt U-förmig profilierte Befestigungsschiene, die in einem Betonträger 2 derart eingebettet ist, daß der den Schienenrücken bildende U-Steg 3 mit der zugekehrten Stegseite 4 des Betonträgers 2 oberflächenbündig abschließt. Nach dem Gießen des Betonträgers 2 unter Einschluß der Schiene 1 können Trapezbleche 5 mittels Schrauben 6 in der üblichen Weise an der Schiene 1 festgelegt werden. Für jede Schraube 6 wird im mittleren Bereich der Schiene 1 je eine Bohrung 7 gefertigt. Diese wird von der Schraube 6 durchgriffen, die ihrerseits einen Schaft mit selbstschneidendem Gewinde besitzt. Alternativ kann auch mit Bohrschrauben gearbeitet werden. Bei größerer Wandstärke der Schiene können Setzbolzen zum Einsatz kommen.According to the first embodiment, shown in Figures 1 to 4, it concerns the Rail 1 around a U-shaped profile in cross section Fastening rail in a concrete beam 2 such is embedded that the one forming the back of the rail U-web 3 with the facing web side 4 of the concrete beam 2 is flush with the surface. After pouring of the concrete beam 2, including the rail 1 can Trapezoidal sheets 5 using screws 6 in the usual Way to be set on the rail 1. For every Screw 6 is in the middle of the rail 1 each a hole 7 made. This is from the screw 6 penetrated, which in turn a shaft with self-tapping Thread. Alternatively, you can use Self drilling screws are worked. With larger wall thickness setting bolts can be used on the rail.

Damit die Schrauben 6 nicht unmittelbar in das Material des Betonträgers 2 eingreifen müssen, ist der U-Raum 8 mit einer einer aus Schaumstoff bestehenden Weichstoffschicht 9 ausgefüllt. Zum besseren Halt der Weichstoffschicht 9 formen die U-Schenkel 10 Hinterschneidungen . Geschaffen sind diese durch dachförmig verlaufende Teilabschnitte 10' und 10'' der U-Schenkel derart, daß die Scheitel beider U-Schenkel in entgegensetzte Richtungen weisen. Die Weichstoffschicht 9 kann auf einer Durchlauf-Füllanlage eingebracht werden, so daß auf vorgefertigte rechteckförmige Streifenelemente verzichtet werden kann, die in das Profil einzukleben wären. So that the screws 6 are not directly in the material of the concrete beam 2 must intervene, the U-space is 8 with a layer of soft material made of foam 9 filled out. For a better hold of the soft material layer 9 form the U-legs 10 undercuts. These are created by roof-shaped Sections 10 'and 10' 'of the U-legs such that the vertices of both U-legs in opposite directions point. The soft material layer 9 can on a Continuous filling system are introduced so that on prefabricated rectangular strip elements are dispensed with that can be glued into the profile.

Als Weichstoffschicht könnten auch andere geeignete Massen dienen. Hohlkörper und Verbundkörper wären ebenfalls denkbar.Other suitable ones could also be used as the soft material layer Serve crowds. Hollow body and composite body would also be conceivable.

Zur Fesselung der Schiene 1 in dem Betonträger 2 dienen an den U-Schenkeln 10 festgelegte Anker 11. In gleicher Querschnittsebene sind jeweils zwei solcher Anker 11 an der Schiene 1 vorgesehen. Jeder Anker 11 ist als V-förmiger Bügel gestaltet und besteht aus gebogenem Rundstahl derart, daß die V-Schenkel 13 zueinander divergieren. Deren Endabschnitte 14 sind durch punktförmige Schweiß-Befestigungsstellen 15 an den U-Schenkeln 10, festgelegt, wobei die Befestigungsstellen jedes Ankers 11 ausschließlich an einer Längsseite der Schiene angeordnet sind. Die Schweißbefestigungsstellen 15 sind den V-Scheiteln 12 abgekehrt und befinden sich auf Höhe der Scheitel der U-Schenkel 10, welche Scheitel günstige Kontaktstellen formen.Serve to tie the rail 1 in the concrete beam 2 on the U-legs 10 fixed anchor 11. In the same Cross-sectional plane are two such anchors 11 each the rail 1 provided. Each anchor 11 is V-shaped The handle is designed and made of curved round steel such that the V-legs 13 diverge from each other. The end portions 14 are punctiform Welding fastening points 15 on the U-legs 10, set, with the attachment points of each anchor 11 arranged only on one long side of the rail are. The welding attachment points 15 are the V-vertices 12 are turned and are at the level of Vertex of the U-leg 10, which apex favorable Form contact points.

Aus Figur 2 geht hervor, da die Bügel 11 in gleichmäßigen Abständen x zueinander an der Schiene 1 festgelegt sind. Dieser Abstand x beträgt bevorzugtermaßen ca. 150 mm. Daher ist auch beim bauseitigen Ablängen eine einwandfreie Verankerung der Schiene ohne besondere Zusatzmaßnahme gewährleistet. Die V-förmig gestalteten Ankerbügel 11 führen auch zu einer in Schienenlängsrichtung hochbeanspruchbaren Bauform, bedingt durch die Dreieckswirkung. Die Abstände könnten auch ein Vielfaches des Abstandes x betragen.From Figure 2 it can be seen that the bracket 11 in uniform Clearances x to each other on rail 1 are. This distance x is preferably approximately 150 mm. Therefore, there is also a cut to length on site perfect anchoring of the rail without any special Additional measure guaranteed. The V-shaped Anchor brackets 11 also lead to one in the longitudinal direction of the rail heavy-duty design, due to the Triangular effect. The distances could also be a multiple of the distance x.

Die zuvor beschriebene Schiene 1 kann zum Zwecke des Transports mit anderen günstig inandergeschachtelt werden, und zwar insbesondere dann, wenn der Winkel zwischen Schienenrücken und U-Schenkeln 10 etwas größer als 90° ist. The rail 1 described above can for the purpose of Transports nested with other cheap especially if the angle between rail back and U-legs 10 slightly larger than 90 °.

Gemäß der zweiten Ausführungsform, dargestellt in den Figuren 5 und 6, ist ebenfalls eine Schiene 16 U-förmigen Querschnitts gewählt. Sie setzt sich zusammen aus dem den Schienenrücken bildenden U-Steg 17 und den U-Schenkeln 18. Letztere bilden auch Hinterschneidungen zur Fesselung der den U-Raum 19 ausfüllenden Weichstoffschicht 20. Die Hinterschneidungen sind in gleicher Weise durch dachförmige Biegung der U-Schenkl 19 derart erzeugt, daß die Dachscheitel gegeneinander gerichtet sind. Das bedeutet, daß die von dem U-Steg 17 ausgehenden Teilabschnitte 18' einen geringeren Winkel als 90° zum U-Steg 17 einschließen. Die anderen Teilabschnitte 18'' dagegen verlaufen zum freien Ende der Schiene 16 hin divergierend. Auf diese Weise werden punktförmige Schweiß-Befestigungsstellen für die als Bügel gestalteten Anker 11 geschaffen. Die entsprechenden Kontaktstellen der U-Schenkel 18 liegen so, daß die Anker 11 annähernd rechtwinklig zum U-Steg 17 ausgerichtet sind. Jeder Endabschnitt 14 der V-Schenkel 13 ist jedoch im Gegensatz zur vorherigen Ausgestaltung durch zwei Punktschweißungen 15' gehalten.According to the second embodiment, shown in FIGS Figures 5 and 6, a rail 16 is also U-shaped Cross-section selected. She sits down together the U-web 17 forming the rail back and the U-legs 18. The latter also form undercuts for capturing the soft material layer filling the U-space 19 20. The undercuts are the same Way by roof-shaped bending of the U-Schenkl 19 such generated that the roof apex directed against each other are. This means that the outgoing from the U-web 17 Sections 18 'an angle less than 90 ° enclose to U-bridge 17. The other sections 18 '', on the other hand, run to the free end of the rail 16 diverging towards. In this way, point-like Welding attachment points for those designed as brackets Anchor 11 created. The appropriate contact points the U-leg 18 are such that the armature 11 approximately are aligned at right angles to U-web 17. However, each end section 14 of the V-leg 13 is in the Contrary to the previous configuration by two spot welds 15 'held.

Gemäß der dritten Ausführungsform, dargestellt in den Figuren 7 bis 9 ist eine Schiene 16 gewählt, die der vorbeschriebenen Schiene entspricht. Die Anker 21 sind nun jedoch von einem in entsprechender Wellenform durchlaufenden und mehrere Anker 21 hintereinanderliegend aufweisenden gebogenen Stab gebildet. Bezüglich desselben handelt es sich um Rundstahl mit profilierter Oberfläche. Es liegt ebenfalls eine V-förmige Gestaltung jedes Ankers 21 vor. Zwischen jeweils zwei solcher Ankerausbiegungen erstreckt sich ein in Schienenlängsrichtung verlaufender geradliniger Zwischenabschnitt 22. Auch diese Ausgestaltung ermöglicht einen geringen Ankerabstand. Zur Festlegung der Anker 21 an den Längsseiten der Schiene 16 dienen die Bügelschenkelenden 23 und die Zwischenabschnitte 22, welche ebenfalls durch Schweißung mit den U-Schenkeln 18 verbindbar sind. Es bilden jedoch nun die vom freien Ende der Schiene 16 divergierend verlaufenden Teilabschnitte 18'' der U-Schenkel 18 die Anschweißflächen für die dann ebenfalls in divergierenden Ebenen zur Schiene liegenden Anker 21. Die V-förmige Gestaltung der Anker 21 und deren Festlegung an der Befestigungsschiene erlauben auch ein Ineinanderschachteln von mehreren Schienen 16 beim Transport. Der U-Raum 19 nimmt die Weichstoffschicht 20 auf, die zufolge der Hinterschneidungen unverlierbar der Schiene 16 zugeordnet ist.According to the third embodiment, shown in FIGS Figures 7 to 9, a rail 16 is selected, the corresponds to the rail described above. The anchors 21 are but now from one that runs in a corresponding waveform and several anchors 21 one behind the other having a curved rod. Regarding the same it is round steel with a profiled surface. There is also a V-shaped design each anchor 21 before. Between two such Anchor bends extend in the longitudinal direction of the rail straight rectilinear section 22. This configuration also enables a low level Anchor spacing. To fix the anchor 21 on the long sides the rail 16 serves the ends of the stirrup legs 23 and the intermediate sections 22, which also by Welding can be connected to the U-legs 18. It However, they now form the free end of the rail 16 diverging sections 18 '' of the U-legs 18 the welding surfaces for the then also Anchors lying in divergent planes to the rail 21. The V-shaped design of the anchors 21 and their Fixing on the mounting rail also allow one Nesting of several rails 16 at Transport. The U space 19 takes the soft material layer 20 on, which, according to the undercuts, cannot be lost is assigned to the rail 16.

Gemäß der vierten Ausgestaltung, dargestellt in den Figuren 10 und 11, ist die Schiene 24 als Flachstreifen gestaltet. An deren beiden Schmallängsseiten 25 sind die zu Ankerbügeln gebogenen Anker 26 festgelegt. Diese sind ebenfalls V-förmig gestaltet und besitzen die untereinander verbundenen V-Schenkel 26' mit der Schiene 24 abgekehrtem, geradlinig verlaufendem V-Scheitel. Die Anker 26 sind Bestandteil eines in Wellenform gebogenen Stabes, für welchen Rundstahl verwendet ist. Die die Endabschnitte benachbarter V-Bügel verbindenden Abschnitte 27, also die Wellenberge, sind mit dem jeweiligen Schienenlängsseitenwand 25 durch Punktschweißung 28 an der Schiene 24 festgelegt derart, daß die auf gleicher Höhe liegenden Anker parallel zueinanderverlaufen. Auch diese Ausgestaltung bringt den Vorteil eines geringen Ankerabstandes, was dem bauseitigen Ablängen sehr entgegenkommt. Strichpuntiert geht aus den Figuren 10 und 11 hervor, daß jede Reihe von hintereinanderliegenden Ankern 26 durch einen parallel zur Schiene 24 verlaufenden Versteifungsdraht 29 untereinander verbunden sein kann. Der Versteifungsdraht 29 erstreckt sich etwa auf mittlerer Länge der Anker 26 und ist bevorzugt außenseitig derselben durch Schweißung an diesen befestigt. Neben einer Versteifung der Anker 26 erhöhen die Versteifungsdrähte 29 auch die Tragfähigkeit der Befestigungschiene 24.According to the fourth embodiment, shown in FIGS Figures 10 and 11, the rail 24 is a flat strip designed. On the two narrow longitudinal sides 25 are the anchors bent to anchor brackets 26 fixed. This are also V-shaped and have the interconnected V-legs 26 'with the rail 24 turned, straight V-part. The anchors 26 are part of a curved wave shape Rod for which round steel is used. The connecting the end sections of adjacent V-brackets Sections 27, i.e. the wave crests, are with the respective one Rail longitudinal side wall 25 by spot welding 28 fixed to the rail 24 such that the on Anchors lying at the same height run parallel to each other. This configuration also has the advantage of one small anchor spacing, which the on-site cutting to length very accommodating. Dashed lines go from the figures 10 and 11 indicate that each row of consecutive Anchor 26 through a parallel to the rail 24 extending stiffening wire 29 with each other can be connected. The stiffening wire 29 extends the anchor 26 is approximately on a medium length preferably on the outside thereof by welding attached this. In addition to stiffening the anchors 26 the stiffening wires 29 also increase the load capacity the fastening rail 24.

Im Bereich zwischen den längskantenseitig befestigten Ankern 26 befindet sich ein die Weichstoffschicht 30 bildender Schaumstoffstreifen, welcher an der Unterseite 31 des Flachstreifens 24 durch Klebung festgehalten ist und zur Schaffung eines betonfreien Innenraumes unterhalb der Schienendecke dient.In the area between the longitudinal edge fastened Anchor 26 is located on soft layer 30 forming foam strips, which at the bottom 31 of the flat strip 24 held by gluing and to create a concrete-free interior serves below the rail ceiling.

Die in den Figuren 12 und 13 aufgezeigte fünfte Version entspricht weitgehend der Ausführungsform gemäß Figur 10 und 11. Die Anker 26 sind abweichend von der vorgenannten Ausführungsform randkantenseitig an der Unterseite 31 des Flachstreifens 24 durch Schweißstellen festgelegt.The fifth version shown in FIGS. 12 and 13 largely corresponds to the embodiment according to the figure 10 and 11. The anchors 26 are different from the aforementioned Embodiment on the edge side on the underside 31 of the flat strip 24 due to welds fixed.

Die in den Figuren 14 und 15 aufgezeigte, sechste Ausführungsform beinhaltet eine im Querschnitt U-förmig gestaltete Schiene 32, bestehend aus dem U-Steg 33 und den beiden parallel zueinanderverlaufenden U-Schenkeln 34. Zwischen den letzteren befindet sich zur Schaffung eines betonfreien Innenraumes eine Weichstoffschicht 35. Diese besteht aus Schaumstoff und besitzt eine geringere Breite als das Innemaß zwischen den U-Schenkeln 34. Befestigt ist die Weichstoffschicht 35 an der Unterseite des U-Steges 33 durch Verklebung.The sixth embodiment shown in FIGS. 14 and 15 includes a U-shaped cross section designed rail 32, consisting of the U-web 33 and the two parallel U-legs 34. Between the latter is creating of a concrete-free interior is a layer of soft material 35. This is made of foam and has one smaller width than the inside dimension between the U-legs 34. The soft material layer 35 is attached to the Underside of the U-web 33 by gluing.

Es sind bei dieser Version Anker 26 verwendet, die denjenigen gemäß Figur 10 und 11 entsprechen. Die Festlegung der Anker 26 erfolgt an der Stirnfläche 36 der U-Schenkel durch Schweißen derart, daß die reihenförmig hintereinanderliegenden Anker 26 des einen Schenkels parallel verlaufen zu den Ankern des anderen Schenkels.Anchors 26 are used in this version correspond to those according to FIGS. 10 and 11. The definition the armature 26 takes place on the end face 36 of the U-legs by welding in such a way that the rows successive anchor 26 of one leg run parallel to the anchors of the other leg.

Die Figuren 16 und 17 betreffend die siebte Ausführungsform und zeigen im Gegensatz zu den vorbeschriebenen Ausführungsformen eine als Ankerschiene ausgebildete Schiene 50. Diese ist im Querschnitt C-profiliert und setzt sich im einzelnen zusammen aus einem Schienenrükken 51 und den rechtwinklig von diesem ausgehenden Schienenseitenwänden 52, an die sich rechtwinklig abgebogene Abschnitte 53 unter Belassung eines Längsschlitzes 54 anschließen. Die Abschnitte 53 verlaufen dabei parallel zum Schienerücken 51.Figures 16 and 17 relate to the seventh embodiment and show in contrast to the above Embodiments designed as an anchor rail Rail 50. This is C-shaped in cross section and is composed in detail of a rail back 51 and the one starting at right angles Rail side walls 52 to which bent at right angles Sections 53 leaving a longitudinal slot 54 connect. The sections 53 run here parallel to the back of the rail 51.

Gemäß Figur 16 ist die Schiene 50 so in eine strichpunktiert veranschaulichte Betonkonstruktion 55 eingelassen, daß die Außenseite der Abschnitte 53 bündig mit der Oberfläche der Betonkonstruktion 55 abschließt. Vor dem Betoniervorgang ist der Innenraum der Schiene 50 mit einer Weichstoffschicht 58 ausgefüllt, die nach dem Aushärten des Betons von der Längsschlitzseite her herausgezogen wird. Dann kann eine strichpunktiert veranschaulichte Ankerkopf-Schraube 57 durch den Längsschlitz 54 eingeführt nach einer 90-Grad-Drehverlagerung in die Hintergriffsstellung gemäß Figur 16 gebracht werden.According to FIG. 16, the rail 50 is thus dash-dotted illustrated concrete structure 55 embedded, that the outside of the sections 53 flush with the surface of the concrete structure 55 completes. In front the concreting process is the interior of the rail 50 filled with a soft material layer 58, which after Hardening of the concrete from the longitudinal slot side is pulled out. Then you can use a dash-dot illustrated anchor head screw 57 through the longitudinal slot 54 introduced after a 90 degree rotation brought into the rear grip position according to Figure 16 will.

Zur Fesselung der Schiene 50 in der Betonkonstruktion 55 dienen an den Schienenseitenwänden 52 durch Schweißung befestigte Anker 58. Es sind in gleicher Querschnittsebene jeweils zwei solcher Anker 58 an der Ankerschiene 50 so festgelegt, daß sie den Schienenrükken 51 überragen. Jeder Anker 58 ist V-förmig gestaltet mit dem Schienenrücken 51 abgekehrt liegendem Scheitel 59. Für die Anker 58 ist Rundstahl verwendet, der so gebogen wird, daß die V-Schenkel 60 zueinander divergieren. Ein Parallelverlauf der Schenkel 60 wäre ebenfalls denkbar. Deren Endabschnitte 60' sind außenseitig an den Schienenseitenwänden 52 angeschweißt.For capturing the rail 50 in the concrete structure 55 serve on the rail side walls 52 by welding attached anchor 58. They are in the same cross-sectional plane two such anchors 58 each Anchor rail 50 set so that it backs the rail 51 tower above. Each anchor 58 is V-shaped with the rail back 51 facing away Vertex 59. Round steel is used for the anchors 58, which is bent so that the V-legs 60 to each other diverge. A parallel course of the legs 60 would be also conceivable. Their end sections 60 'are on the outside welded to the rail side walls 52.

Der Abstand zweier benachbarter Anker ist entsprechend dem Einsatzzweck so gewählt, daß nach einem bauseitigen Ablängen eine einwandfreie Verankerung der Ankerschiene 50 ohne Zusatzmaßnahmen gewährleistet ist. Ebenfalls besteht bei dieser Lösung der Vorteil einer Ineinanderschachtelung zum Zwecke des Transport.The distance between two adjacent anchors is corresponding the application is chosen so that after an on-site Cut a perfect anchorage of the anchor channel 50 is guaranteed without additional measures. Likewise this solution has the advantage of nesting for the purpose of transportation.

Die Figuren 18 und 19 betreffend die achte Ausführungsform. Diese bezieht sich wieder auf eine als Befestigungsschiene gestaltete Schiene 61, welche im Querschnitt U-profiliert ist. Der U-Steg 62 bildet den Schienenrücken, von welchem die seitwärts abgewinkelten U-Schenkel 63 in leichtem divergierenden Verlauf ausgehen. Der Innenraum der Schiene 61 ist mit einer aus Schaumstoff bestehenden Weichstoffschicht 64 ausgefüllt.Figures 18 and 19 relate to the eighth embodiment. This again refers to a mounting rail designed rail 61, which in cross section U-shaped. The U-web 62 forms the Rail back, of which the angled sideways U-legs 63 go out in a slightly divergent course. The interior of the rail 61 is one Foam existing soft layer 64 filled.

In entsprechendem Abstand voneinander sind an jedem U-Schenkel 63 bügelförmige Anker 65 festgelegt derart, daß die Endabschnitte 66' der Schenkel 66 jedes Ankers 65 ausschließlich an einer Schienenlängsseitewand der Schiene 61 angebracht sind. In gleicher Querschnittsebene der Schiene 61 sind jeweils zwei Anker angeordnet. Im Grundriß gesehen, besitzt jeder Anker 65 eine leichte V-Form, d.h. daß die V-Schenkel 66, ausgehend von ihrem gerundet verlaufenden V-Scheitel 67, divergieren. Ein Parallelverlauf der V-Schenkel 66 wäre jedoch auch möglich. Die bügelförmigen Anker 65 besitzen unterhalb der U-Schenkel 63 eine zur Schienenlängsmittelebene E-E gerichtete Abbiegung 68, an die sich eine gegensinnige Abbiegung 69 anschließt unter Bildung eines Z-Verlaufes des Ankers 65 in seiner Seitenansicht, vergleiche Figur 19. Die Abbiegungen 69, die ebenso wie die Abbiegungen 68 Bestandteil der V-Schenkel 66 sind, verlaufen mit geringem Abstand zur Schienenlängsmittelebene und parallel zueinander. Die Endabschnitte 66' sind ebenfalls mittels Schweiß-Befestigungsstellen an den Längsseiten der U-Schenkel 63 angeordnet.At an appropriate distance from each other U-legs 63 bow-shaped anchors 65 set in such a way that the end portions 66 'of the legs 66 of each anchor 65 only on a longitudinal side wall of the Rail 61 are attached. In the same cross-sectional plane two anchors are arranged on the rail 61. Viewed in plan, each anchor 65 has a light one V shape, i.e. that the V-leg 66, starting from their rounded V-apex 67, diverge. A parallel course of the V-legs 66 would also be possible. The bow-shaped anchors 65 have below the U-leg 63 a to the longitudinal plane of the rail E-E directional turn 68 to which an opposite Turn 69 connects to form a Z course the anchor 65 in its side view, compare figure 19. The turns 69, as well as the turns 68 are part of the V-legs 66, run with short distance to the longitudinal plane of the rails and parallel to each other. The end portions 66 'are also by means of welding attachment points on the long sides the U-leg 63 arranged.

Bei der neunten Ausführungsform, dargestellt in Figur 20 bis 22, tragen gleiche Bauteile gleiche Bezugsziffern wie die vorangegangene achte Ausführungsform. Jeweils zwei bügelförmige Anker 69,70 sind ebenfalls in gleicher Querschnittsebene vorgesehen derart, daß die Endabschnitte der V-Schenkel 77,78 durch Punktschweißung außenseitig der U-Schenkel 63 festgelegt sind. Ferner sind die Anker 69,70 Z-förmig gebogen und enthalten demgemäß Abbiegungen 71,72 bzw. 73,74. Die Abbiegungen zweier sich gegenüberliegender Anker sind so gestaltet, daß zumindest die Scheitelabschnitte 75,76 ineinandergeschachtelt sind. Daß heißt, daß sie in der Längsmittelebene E-E der Schiene 61 liegen. Erreicht ist die Ineinanderschachtelung dadurch, daß die Abbiegungen 71 der V-Schenkel 77 zur Längsmitte des Ankers 69 hin zulaufen und in die Abbiegung 72 übergehen. Der Scheitelabschnitt 75 hat einen geringeren Radius und liegt innerhalb des Scheitelabschnittes 76 des anderen Ankers 70 und ermöglicht dadurch die Ineinanderschachtelung.In the ninth embodiment, shown in Figure 20 to 22, the same components have the same reference numbers like the previous eighth embodiment. Two bow-shaped anchors 69, 70 are also in each case same cross-sectional plane provided such that the End sections of the V-legs 77.78 by spot welding are defined on the outside of the U-leg 63. Furthermore, the anchors 69, 70 are bent and contained in a Z-shape accordingly turns 71.72 and 73.74. The turns two opposite anchors are designed that at least the vertices 75,76 are nested are. That means that they are in the median longitudinal plane E-E of the rail 61 lie. That has been achieved Nesting in that the turns 71 the V-leg 77 towards the longitudinal center of the armature 69 run in and merge into turn 72. The apex section 75 has a smaller radius and lies within the apex portion 76 of the other anchor 70 and thereby enables nesting.

Rail (1,16,50,61) embeddable in a concrete carrier (2) or the like for the building industry for securing in particular facade cladding members (5) by means of screws (6) entering into interlocking engagement with the rail, the rail having on both longitudinal sides of said rail succeeding spaced-apart anchors (11,21,58,65,69,70), which are secured by welding, whereby in order to provide an inner space without concrete beneath the rail cover, there is associated with the latter a layer formed particularly of soft material (9,20,56,64), and whereby the attachment points of each anchor are located exclusively on one longitudinal side of the rail,
    characterised in that each anchor (11,21,58,65,69,70) is formed as a substantially V-shaped bow, the apex of the V of which (12,59,67,75,76) lies facing away from the weld attachment points, the latter being formed in the area of the end sections (14,23,60',66') extending at a spacing apart from one another and in contact, on one single rail longitudinal side wall, of the V-bows 13,23,60,66,77,78).
  2. Rail (24,32) embeddable in a concrete carrier or the like for the building industry for securing in particular facade cladding members by means of screws entering into interlocking engagement with the rail, the rail (24,32) having on both longitudinal sides of said rail succeeding spaced-apart anchors (26), which are secured by welding, whereby in order to provide an inner space without concrete beneath the rail cover, there is associated with the latter a layer (30,35), formed particularly of soft material, and whereby the attachment points of each anchor are located exclusively on one longitudinal side of the rail, characterised in that each anchor (26) is formed as a substantially V-shaped bow, the apex of the V of which lies facing away from the weld attachment points, the latter being attached in contact on one single rail longitudinal side wall in such a way that a section (27) connecting the two V-arm end sections of adjacent V-bows, is welded to the longitudinal side edge of the rail.
  3. Rail according to claim 1 or 2, characterised in that the anchor bows (21,26) are formed by a bent bar extending in a corresponding corrugated shape and having a plurality of anchors in succession.
  4. Rail according to claim 3, characterised in that the bar is a round steel section with profiled surface.
  5. Rail according to one or more of the preceding claims, characterised by a rectilinear intermediate section (22) between two anchor outward bends and extending in the longitudinal direction of the rail.
  6. Rail according to one or more of the preceding claims, characterised by a reinforcing wire (29) parallel to the rail (24) and at a spacing therefrom, connecting the bow arms (26') at about the middle of their length.
  7. Rail according to one or more of the preceding claims, characterised in that the rail is formed as an attachment rail (1,16,32) with U-shaped cross-section, with anchors (11,21,26) secured to the U-arms and projecting over them.
  8. Rail according to one or more of the preceding claims, characterised in that the rail is formed as an anchor rail (50) with a C-shaped cross-section, with anchors (58) attached to the rail side walls (52) extending at right angles to the back of the rail (51), and projecting over the back of the rail (51).
  9. Rail according to one or more of the preceding claims, characterised by a soft material layer (9,20) filling the U-space (18,19) of the attachment rail (1,16) which is U-profiled in cross-section, in such a way that the U-arms (10',10'',18',18'') form undercuts for capturing the layer (9,20) of soft material.
  10. Rail according to one or more of the preceding claims, characterised in that the undercuts form spot weld attachment points for the anchor (1).
  11. Rail according to one or more of the preceding claims, characterised in that the undercuts are such that the part sections (18'') of the U-arms (18) diverging from the free end of the attachment rail (16) form the weld surfaces for anchors (21) lying in planes divergent to the attachment rail (16).
  12. Rail according to one or more of the preceding claims, characterised in that the anchors (26) are welded in front of the end surface (36) of the U-arms (34) of the attachment rail (32) forming the rail longitudinal side edge.
  13. Rail according to one or more of the preceding claims, characterised in that the bow-shaped anchor (65) has a bent portion (68) aligned towards the longitudinal medial plane (E-E) of the rail.
  14. Rail according to one or more of the preceding claims, characterised in that there connects with the bent portion (68), a contrary bent portion (69), forming a Z configuration of the anchor (65), seen in the crosssection of the rail (61).
  15. Rail according to one or more of the preceding claims, characterised in that, when anchors (69,70) are located opposite one another, the bent portions (71,72,73,74) are so configured that at least the apex sections (75,76) of the anchors are nested one in the other.
