Abstract

A tie anchor for use in reinforced sandwich panels of cast concrete, to support a face panel on a carrier panel by reaching through an intermediate insulating panel, the tie anchor being a sheet metal stamping with a central A-shaped end portion on one axial end and a V-shaped recess flanked by two tapered end portions on the other axial end. Hook portions formed of the tapered end portions are engageable over a rod of a reinforcing steel rod mesh and attachable thereto by means of positioning rods which are inserted through transverse positioning bores in the hook portions.

Description

Die Erfindung betrifft einen Verbundanker einer Schichtverbundplatte der im Oberbegriff des Anspruches 1 angegebenen Art.The invention relates to a composite anchor of a laminated panel of the type specified in the preamble of claim 1.

Ein aus der Praxis bekannter, aus rostfreiem Stahl hergestellter Verbundanker dieser Art, dessen einander abgewandten Enden beim Formen der Trag- und der Vorsatzplatte aus Beton in diesen lösbar eingebettet werden, hat die Form einer rechteckigen, ebenen Platte mit nahe den Schmalseiten angeordneten Löchern zur Durchführung von Ankerstäben und die den Betonstahlmatten der Trag- bzw. Vorsatzplatte zugewandten Enden dieses Verbundankers werden zur zugfesten Verbindung der Betonstahlmatten miteinander durch je eine Maschenmatte hindurchgesteckt, um anschliessend daran die an die Betonstahlmatten anlegbaren Ankerstäbe einfügen zu können.A known from practice, made of stainless steel composite anchor of this type, the opposite ends of which are releasably embedded in the concrete when forming the supporting and the facing plate, has the shape of a rectangular, flat plate with holes arranged near the narrow sides for passage of anchor rods and the ends of this composite anchor facing the reinforcing steel mats of the supporting or facing plate are pushed through a mesh mat for the tensile connection of the reinforcing steel mats to each other, in order to subsequently be able to insert the anchor rods that can be placed on the reinforcing steel mats.

Dieser bekannte Verbundanker lässt sich zwar relativ einfach und mühelos durch die Isolierschicht, welche meistens aus Schaumkunststoff besteht, hindurchstecken, aber bei diesem bekannten Verbundanker ist keine lagerichtige und lagesichere Halterung dessen an den Betonstahlmatten und relativ zu diesen sichergestellt, bevor die durch Urformen aus Beton hergestellten Trag-und Vorsatzplatten ausgehärtet sind, weil der Verbundanker sowohl beim Durchstecken durch die Isolierplatte als auch beim Einfügen des Frischbetons in die Schichtverbundplattenform um die längsseits an den Betonstahlmatten anliegenden Ankerstäbe scharnieren kann, so dass sich daraus auch lageunrichtige Anordnungen der Betonstahlmatten zueinander ergeben können.This known composite anchor can be inserted relatively easily and effortlessly through the insulating layer, which usually consists of foam plastic, but with this known composite anchor there is no correct and positionally secure mounting of it on the reinforcing steel mats and relative to them, before they are made from concrete by primary molding The supporting and facing plates are hardened because the composite anchor can hinge around the anchor bars lying along the side of the reinforcing steel mats both when pushing through the insulating plate and when inserting the fresh concrete into the layered composite panel form, so that incorrectly aligned arrangements of the reinforcing steel mats can also result from each other.

Darüber hinaus ist es auch möglich, dass zum Beispiel bei relativ engen Betonstahlmattenmaschen bzw. dann, wenn die Maschen der der Tragplatte zugeordneten Betonstahlmatte den Maschen der der Vorsatzplatte zugeordneten Betonstahlmatte nicht exakt zueinander gegenüberstehen oder bei aus Gründen der Tragfähigkeit breiter als Betonstahlmattenmaschen bemessenen Verbundankers dessen Enden nicht durch die Betonstahlmattenmaschen hindurchgesteckt werden können.In addition, it is also possible that, for example, in the case of relatively narrow reinforcing steel mesh meshes or when the meshes of the reinforcing steel mesh assigned to the supporting plate do not exactly oppose the meshes of the reinforcing steel mesh assigned to the facing plate, or in the case of composite anchors whose ends are wider than reinforcing steel mesh meshes, the ends thereof cannot be inserted through the reinforcing mesh mesh.

In diesen Fällen hilft man sich bislang derart, dass durch Ausschneiden von Teilen der Betonstahlmatte eine gegenüber dem Verbundanker grössere Durchstecköffnung geschaffen wird. Hierdurch vermindert man aber auch die Festigkeit der Trag- und/oder Vorsatzplatte und dies gerade im Bereich der Verbindungsstellen.In these cases, it has so far been helped that by cutting out parts of the reinforcing steel mat, a larger push-through opening is created compared to the composite anchor. This also reduces the strength of the support and / or facing plate, especially in the area of the connection points.

Aufgabe der Erfindung ist es nun, einen Verbundanker der im Oberbegriff des Anspruches 1 angegebenen Art unter Beibehaltung der beim Stand der Technik bereits erreichten Vorteile, nämlich, dass der Verbundanker bei der Herstellung der Schichtverbundplatte relativ mühelos durch die Isolierplatte hindurchgesteckt und auch relativ einfach und preiswert hergestellt werden kann, darüber hinaus derart zu verbessern, dass eine erheblich einfachere Herstellung der Schichtverbundplatte und eine quasi zwangsläufig richtige Anordnung sowohl der Plattenbewehrungen zueinander als auch der Verbundanker relativ zu letzteren erreichbar ist, ohne die Stabilität sowohl des Verbundankers als auch der Platten zu mindern.The object of the invention is now to provide a composite anchor of the type specified in the preamble of claim 1 while maintaining the advantages already achieved in the prior art, namely that the composite anchor is relatively effortlessly inserted through the insulating plate in the production of the layered composite panel and also relatively simple and inexpensive can also be produced in such a way that a considerably simpler production of the layered composite slab and an almost inevitable correct arrangement of both the plate reinforcements relative to one another and the composite anchor relative to the latter can be achieved without reducing the stability of both the composite anchor and the slabs.

Die Lösung dieser Aufgabe kennzeichnet sich durch folgende Merkmale:

  • a) der Verbundanker hat den Betonstahlmatten o.ä. zugewandte, zu ihren freien Enden hin sich in der Breite etwa keilförmig vermindernde Endteile,
  • b) mindestens an einem Verbundankerende sind zwei mit Abstand nebeneinander angeordnete, vorgenannte Endteile vorgesehen,
  • c) die Löcher zur Aufnahme der Anker-Stäbe sind in den vorgenannten Endteilen angeordnet,
  • d) an dem einen Verbundankerende ist an dem einen bzw. sind an beiden, vorgenannten Endteilen einen Betonstahlmattenstab umfassbare Haken mit zum anderen Verbundankerende hinzielenden Hakenspitzen angebogen und
  • e) pro Haken sind in der Hakenspitze und in dem letzterer gegenüber befindlichen Hakenteil Löcher mit solch einem Abstand vom Hakengrund angeordnet, dass durch beide vorgenannten Löcher ein Ankerstab an den vom Haken umfassbaren Betonstahlmattenstab anlegbar hindurchsteckbar ist.
The solution to this problem is characterized by the following features:
  • a) the composite anchor has the reinforcing steel mesh or similar. facing end parts, which decrease in width towards their free ends, approximately wedge-shaped,
  • b) at least at one composite anchor end, two aforementioned end parts are provided next to one another at a distance,
  • c) the holes for receiving the anchor rods are arranged in the aforementioned end parts,
  • d) on the one end of the composite anchor is hooked on the one or on both of the aforementioned end parts a reinforcing steel mesh rod with hooks pointing toward the other end of the composite anchor and
  • e) holes are arranged per hook in the hook tip and in the hook part located opposite the latter at such a distance from the hook base that an anchor rod can be inserted through the aforementioned holes onto the reinforcing steel mesh rod that can be enclosed by the hook.

Hierdurch sind die vorgenannten relativ schlanken Endteile zum Beispiel auch bei mehr oder weniger grossem seitlichen Versatz der Betonstahlmattenmaschen zueinander oder auch bei gegenüber der Breite des Verbundankers kleineren Betonstahlmattenmaschen dennoch zur Verbindung der Betonstahlmatten miteinander in deren Maschen einsteckbar. Zudem wird der Verbundanker durch die im Bereich des oder der Haken vorgesehenen, doppelten Abstützstellen nunmehr relativ zu den Betonstahlmatten unverdrehbar gehaltert. Auch kann der Verbundanker mit seinem geraden Endteil mühelos durch die Isolierschicht hindurchgesteckt werden, ohne dass dabei unbeabsichtigte Lageänderungen der Isolierschicht relativ zur bereits angeschlossenen Betonstahlmatte zu befürchten sind.As a result, the aforementioned relatively slender end parts can be inserted, for example, even with a greater or lesser lateral offset of the reinforcing steel mesh meshes or even with reinforcing steel mesh meshes that are smaller than the width of the tie rod for connecting the reinforcing steel meshes together in their meshes. In addition, the composite anchor is now held non-rotatably relative to the reinforcing steel mesh by the double support points provided in the area of the hook or hooks. With its straight end part, the composite anchor can also be effortlessly inserted through the insulating layer without fear of unintentional changes in the position of the insulating layer relative to the already connected reinforcing steel mat.

Darüber hinaus kann der Verbundanker durch Ausschneiden aus Blech preiswert hergestellt werden.In addition, the composite anchor can be manufactured inexpensively by cutting it out of sheet metal.

Eine vorteilhafte Weiterbildung besteht hierzu darin, dass einem in der Breite sich zum freien Ende hin etwa keilförmig vermindernden Endteil des einen ersten Verbundankerendes am anderen zweiten Verbundankerende eine zwischen zwei mit Abstand nebeneinander angeordneten, etwa keilförmigen Endteilen angeordnete Aussparung gegenübersteht, die zum am ersten Verbundankerende vorgesehenen, etwa keilförmig sich verjüngenden Endteil deckungsgleich ausgebildet und zu einer zur Längsachse des Verbundankers rechtwinklig verlaufenden Achse symmetrisch angeordnet ist, wobei vorzugsweise ferner der Verbundanker zueinander parallel verlaufende Längsseiten hat, die Aussparung und der eine am anderen Verbundankerende angeordnete, sich keilförmig verjüngende Endteil im wesentlichen jeweils die Form eines gleichschenkligen Dreiecks haben und zur Mittellängsachse symmetrisch angeordnet sind.An advantageous further development consists in that an end part of the first composite anchor end which decreases in width towards the free end of the first composite anchor end at the other second composite anchor end is opposed by a recess arranged between two, approximately wedge-shaped end parts which are spaced apart and which are provided at the first composite anchor end , approximately wedge-shaped tapering end part is congruent and is arranged symmetrically to an axis running at right angles to the longitudinal axis of the tie rod, wherein preferably the tie rod also has longitudinal sides running parallel to each other, the recess and the wedge-shaped tapered end part arranged on the other tie rod end essentially each the shape of an isosceles triangle have and are arranged symmetrically to the central longitudinal axis.

Hierdurch ist es möglich, die Verbundanker aus Blechstreifen, deren Breite der Breite eines Verbundankers entspricht, abfallfrei auszuschneiden.This makes it possible to cut out the composite anchors from sheet metal strips, the width of which corresponds to the width of a composite anchor, without waste.

Dabei kann die grösste Breite der Aussparung und die grösste Breite des der Aussparung am anderen Verbundankerende angeordneten, sich etwa keilförmig verjüngenden Endteiles kleiner als die Gesamtbreite des Verbundankers sein.The greatest width of the cutout and the greatest width of the end part arranged at the other composite anchor end and tapering in a wedge shape can be smaller than the total width of the composite anchor.

Eine unter Umständen bevorzugte Weiterbildung des vorbeschriebenen Gegenstandes, die die Herstellung der Schichtverbundplatte sowohl nach dem bekannten Positiv- als auch nach dem Negativ-Verfahren ermöglicht, ist im Anspruch 5 offenbart.A possibly preferred development of the above-described object, which enables the production of the layered composite panel both by the known positive and by the negative method, is disclosed in claim 5.

Weitere vorteilhafte Ausgestaltungen kennzeichnen die Ansprüche 6 und 7.Claims 6 and 7 characterize further advantageous configurations.

Gemäss der Fig. 1 ist in eine Schichtverbundplatte, die im wesentlichen aus einer dicken Tragplatte 1, einer dünnen Vorsatzplatte 2 und einer Isolierplatte 3 besteht, ein Verbundanker 4 eingefügt.According to FIG. 1, a composite anchor 4 is inserted into a composite layer plate, which essentially consists of a thick support plate 1, a thin facing plate 2 and an insulating plate 3.

Die Trag- und die Vorsatzplatte 1, 2 bestehen aus Beton, in die jweils eine Betonstahlmatte 5 bzw. 6 eingebettet sind.The supporting and facing plates 1, 2 are made of concrete, in each of which a reinforcing steel mat 5 or 6 are embedded.

Die Isolierplatte 3 besteht aus Schaumkunststoff. Der im wesentlichen ebene, aus rostfreiem Stahlblech ausgeschnittene, beispielsweise 1,5 mm dicke Verbundanker 4 (besonders deutlich in den Fig. 2 bis 5) mit zueinander parallel verlaufenden Längsseiten 7 hat an einem Ende einen dreieckförmigen Endteil 8, welcher zur Längsmittelachse des Verbundankers symmetrisch ausgebildet ist.The insulating plate 3 is made of foam plastic. The essentially flat, cut out of stainless steel sheet, for example 1.5 mm thick composite anchor 4 (particularly clearly in FIGS. 2 to 5) with mutually parallel longitudinal sides 7 has at one end a triangular end part 8 which is symmetrical to the longitudinal central axis of the composite anchor is trained.

Die grösste Breite dieses Endteiles 8 ist kleiner als der Abstand der Längsseiten 7 voneinander.The greatest width of this end part 8 is smaller than the distance of the long sides 7 from one another.

Am anderen Ende des Verbundankers ist eine zur Längsmittenachse symmetrisch angeordnete, dreieckförmige Aussparung 9 vorgesehen, durch die sich an jenem Verbundankerende zwei, durch die Aussparung 9 mit Abstand voneinander angeordnete, zu ihrem freien Ende hin sich keilförmig verjüngende Endteile 10 und 11 ergeben. Der Endteil 8 und die Aussparung 9 sind deckungsgleich ausgebildet, so dass der Verbundanker aus einem Blechstreifen, der die gleiche Breite wie der Verbundanker hat, abfallfrei ausgeschnitten werden kann. (Fig. 2).At the other end of the composite anchor there is a triangular recess 9 arranged symmetrically to the longitudinal center axis, through which two end parts 10 and 11 tapering in a wedge shape towards their free end result at that composite anchor end. The end part 8 and the recess 9 are congruent so that the composite anchor can be cut out of a sheet metal strip that has the same width as the composite anchor without waste. (Fig. 2).

Die Ecken sind bevorzugter Weise abgerundet, um unter anderem Verletzungsgefahren zu mindern.The corners are preferably rounded in order, among other things, to reduce the risk of injury.

Gemäss den Fig. 1, 3 und 4 sind die Endteile 10 und 11 zu Haken 12 bzw. 13 umgeformt, deren Hakenspitzen zum Endteil 8 hinzielen, wobei jeweils die Hakenspitzen mit der ursprünglichen Ebene einen Winkel von etwa 170° einschliessen, so dass die Haken in die Hakenmäuler gleichartiger Verbundanker eingesteckt werden können, um den Raumbedarf während der Lagerung und des Transportes der Verbundanker zu mindern.1, 3 and 4, the end parts 10 and 11 are formed into hooks 12 and 13, respectively, the hook tips of which point towards the end part 8, the hook tips in each case enclosing an angle of approximately 170 ° with the original plane, so that the hooks can be inserted into the hook mouths of similar composite anchors to reduce the space required during storage and transportation of the composite anchors.

In jedem Haken 12, 13 sind in der Hakenspitze und dem letzterer gegenüberliegenden Hakenteil Löcher 14 und 15 so angeordnet, dass, wie aus der Fig. 1 ersichtlich, durch diese Löcher 14 und 15 ein Ankerstab 16 so hindurchgesteckt werden kann, dass sich der Ankerstab 16 an einem vom Haken 12 bzw. 13 umfassten Stab der Betonstahlmatte 5 längsseits anlegt, womit der Verbundanker 4 rechtwinklig von der Betonstahlmatte 5 abstrebend nahezu spielfrei gehalten wird.Holes 14 and 15 are arranged in each hook 12, 13 in the hook tip and the hook part opposite the latter so that, as can be seen from FIG. 1, an anchor rod 16 can be inserted through these holes 14 and 15 in such a way that the anchor rod 16 is placed alongside on a rod of the reinforcing steel mat 5 encompassed by the hooks 12 and 13, whereby the composite anchor 4 is kept at a right angle from the reinforcing steel mat 5 with almost no play.

Hierbei ist die Umbiegung der Endteile 10 und 11 so durchgeführt, dass zwei Löcher 14 und 15 so gegenüberliegen, dass ihre gemeinsame Mittelachse (bzw. die Achse des Ankerstabs 16) senkrecht auf dem Verbundanker steht.Here, the bending of the end parts 10 and 11 is carried out in such a way that two holes 14 and 15 lie opposite each other so that their common central axis (or the axis of the anchor rod 16) is perpendicular to the composite anchor.

Es ist auch möglich, die räumliche Zuordnung dieser Löcher 14, 15 so zu wählen, dass die Ankerstäbe 16 nicht mehr senkrecht zum Verbundanker gehalten werden, sondern mit einem vorgebbaren Neigungswinkel. Damit erreicht man eine Schrägstellung des Verbundankers 4 bezüglich der Ebenen der Tragplatte 1 und der Vorsatzplatte 2. Kombiniert man mindestens zwei Verbundanker mit unterschiedlichem Neigungswinkel, ergibt sich eine verbesserte Steifigkeit der Schichtverbundplatte in dem Sinn, dass eine Parallelverschiebung von Tragplatte 1 und Verbundplatte 2 ausgeschlossen wird (Fig. 7).It is also possible to choose the spatial assignment of these holes 14, 15 such that the anchor rods 16 are no longer held perpendicular to the composite anchor, but with a predeterminable angle of inclination. This achieves an inclination of the composite anchor 4 with respect to the planes of the support plate 1 and the facing plate 2. If at least two composite anchors with different angles of inclination are combined, there is an improved rigidity of the composite layer plate in the sense that a parallel displacement of the support plate 1 and composite plate 2 is excluded (Fig. 7).

Die erwähnte räumliche Zuordnung der Löcher 14, 15 kann beispielsweise durch gezielte Umbiegung der Endteile 10, 11 erreicht werden oder auch durch herstellerseitige Anbringung zusätzlicher Löcher. Letztere Methode hat den Vorteil, dass hierbei noch bauseits festgelegt werden kann, ob ein Verbundanker senkrecht zur Ebene der Verbundschichtplatte oder dazu geneigt eingebaut werden soll.The spatial assignment of the holes 14, 15 mentioned can be achieved, for example, by deliberately bending the end parts 10, 11 or by making additional holes on the part of the manufacturer. The latter method has the advantage that it can still be specified on site whether a composite anchor should be installed perpendicular to the plane of the composite layer plate or inclined to it.

Auch im Endteil 8 sind, wie aus den Fig. 2 und 5 besonders deutlich ersichtlich, mehrere mit Abstand voneinander angeordnete Löcher 17 vorgesehen, durch die ein an der Betonstahlmatte 6 sich zugfest abstützender Ankerstab 16 hindurchgesteckt ist.Also in the end part 8, as can be seen particularly clearly from FIGS. 2 and 5, a plurality of holes 17 arranged at a distance from one another are provided, through which an anchor rod 16, which is supported on the reinforcing steel mat 6, is inserted.

Die in Fig. 1 gezeigte Schichtverbundplatte ist wie folgt nach dem sogenannten Positiv-Verfahren hergestellt worden.The laminated composite panel shown in FIG. 1 was produced as follows by the so-called positive method.

Hierzu ist in eine nicht dargestellte Schichtverbundplattenform zunächst die Betonstahlmatte 5 unter Zuhilfenahme von bekannten, nicht dargestellten Abstandhaltern, mit Abstand vom Boden der Form eingefügt worden. Alsdann ist der Verbundanker 4, wie aus der Fig. 1 ersichtlich, an einem Stab der Betonstahlmatte 5 angehängt, und mit zwei jeweils die Löcher 14 und 15 der Haken 12 und 13 durchgreifenden Ankerstäben 16 fixiert worden. Danach ist die Tragplatte 1 gegossen worden, auf welche dann die Isolierplatte 3 aufgelegt worden ist. Dabei ist der Verbundanker 4 mit seinem freien, geraden Endteil durch die Isolierplatte 3 hindurchgesteckt worden, wobei der Verbundanker infolge seiner schlanken Form seine Durchstecköffnung mühelosselbst bildet.For this purpose, the reinforcing steel mat 5 has first been inserted into a layered composite panel mold, not shown, with the aid of known spacers, not shown, at a distance from the bottom of the mold. Then, as can be seen from FIG. 1, the composite anchor 4 is attached to a rod of the reinforcing steel mat 5, and with two holes 14 and 15 of the hooks 12 and 13 penetrating anchor rods 16 have been fixed. Thereafter, the support plate 1 was cast, on which the insulating plate 3 was then placed. Here, the composite anchor 4 has been inserted with its free, straight end part through the insulating plate 3, the composite anchor forming its push-through opening with ease due to its slim shape.

Hiernach ist die Betonstahlmatte 6 in die Form lagerichtig eingebracht worden, wobei auch hier nicht dargestellte Abstandhalter für einen lagerichtigen Abstand der Betonstahlmatte 6 von der Isolierplatte 3 sorgen, und wobei der Endteil 8 durch eine Masche der Betonstahlmatte 6 hindurchgesteckt und mittels eines mindestens ein Loch 17 des Endteiles 8 durchgreifenden, an der Betonstahlmatte 6 sich längsseits abstützenden Ankerstabes 16 zugfest festgelegt worden ist. Schliesslich ist dann die Vorsatzplatte gegossen worden.Thereafter, the reinforcing steel mat 6 has been inserted in the correct position, with spacers (not shown) ensuring that the reinforcing steel mat 6 is in the correct position from the insulating plate 3, and the end part 8 is inserted through a mesh of the reinforcing steel mat 6 and by means of at least one hole 17 of the end part 8, which is fixed on the reinforcing steel mat 6 and is supported longitudinally on the anchor rod 16. Finally, the facing plate was cast.

Sollte es sich dabei herausstellen, dass der Endteil 8 zu lang ist, kann der über den Ankerstab 16 vorstehende Teil mühelos umgebogen werden, damit auch der gesamte Endteil 8 gänzlich in den Beton eingebettet wird.If it turns out that the end part 8 is too long, the part protruding over the anchor rod 16 can be bent over effortlessly, so that the entire end part 8 is also completely embedded in the concrete.

Selbstverständlich sind wie beim Stand der Technik in einer Schichtverbundplatte mehrere Verbundanker 4 mit Abstand voneinander angeordnet.Of course, as in the prior art, a plurality of composite anchors 4 are arranged at a distance from one another in a layered composite panel.

Wie besonders aus der Fig. 1 ersichtlich, können mit dem erfindungsgemässen Verbundanker 4 durch die zwei von den Haken 12 und 13 und die ihnen zugeordneten Ankerstäbe 16 gebildeten, mit Abstand voneinander angeordneten Verbindungsstellen grosse, von der Vorsatzplatte 2 ausgeübte Scherkräfte auf die Tragplatte 1 übertragen werden.As can be seen particularly from FIG. 1, with the composite anchor 4 according to the invention, large shear forces exerted by the attachment plate 2 can be transmitted to the support plate 1 by the two connecting points, which are formed by the hooks 12 and 13 and the associated tie rods 16 and are arranged at a distance from one another will.

Soll entsprechend dem sogenannten Negativ-Herstellungsverfahren zur Herstellung einer Schichtverbundplatte zuerst deren Vorsatzplatte 2 geformt werden, sind Verbundanker der in der Fig. 5 gezeigten Art zu verwenden, wobei der einen Haken 18 aufweisende Endteil 8 mit der Betonstahlmatte 6 mittels eines Ankerstabes 16 verbunden wird, während die hier hakenfreien Endteile 10 und 11 mittels Ankerstäben 16 an der Betonstahlmatte 5 befestigt werden.If, according to the so-called negative manufacturing process for producing a laminated composite panel, the facing panel 2 is to be formed first, composite anchors of the type shown in FIG. 5 are to be used, the end part 8 having a hook 18 being connected to the reinforcing steel mat 6 by means of an anchor rod 16, while the end parts 10 and 11 which are not hooked here are fastened to the reinforcing steel mat 5 by means of anchor rods 16.

Beide Verbundankerarten, nämlich die gemäss den Fig. 1, 3 und 4 und die gemäss der Fig. 5, können aus dem gleichen Blechzuschnitt (Fig. 2) hergestellt werden, woraus sich erhebliche Herstellungs- und Lagervereinfachungen ergeben.Both types of composite anchors, namely those according to FIGS. 1, 3 and 4 and those according to FIG. 5, can be produced from the same sheet metal blank (FIG. 2), which results in considerable manufacturing and storage simplifications.

Der in Fig. 6 dargestellte Verbundanker eignet sich sowohl für das Positiv- als auch das Negativ-Herstellungsverfahren. Allerdings ist dieser Verbundanker nicht gänzlich abfallfrei aus einem Blechstreifen auszuschneiden, wobei in beiden Fällen der Abfall, der sich durch das Ausschneiden der Löcher 14, 15 und 17 ergibt, unberücksichtigt ist.The composite anchor shown in Fig. 6 is suitable for both the positive and the negative manufacturing process. However, this composite anchor is not to be cut out of a sheet metal strip entirely without waste, and in both cases the waste resulting from cutting out the holes 14, 15 and 17 is not taken into account.

Anstelle von Betonstahlmatten können auch andere Bewehrungen vorgesehen werden.Instead of reinforcing steel mesh, other reinforcements can also be provided.

Die Erfindung ist auch für solche Schichtverbundplatten anwendbar, wobei zwischen der Tragplatte und der Vorsatzplatte als Isolierung lediglich Luft vorgesehen ist.The invention can also be used for such laminated composite panels, wherein only air is provided as insulation between the support panel and the facing panel.
