Description

Die Erfindung betrifft eine Vorrichtung zum Verwahren von Bewehrungsstählen für Verbindungsbereiche von Beton-Bauwerken in der Form eines langgestreckten, im wesentlichen streifenförmigen Körpers, in den herausbiegende Verbindungsbereiche der Bewehrungsstähle eingebettet sind, deren Verankerungsbereiche aus einer breiten Längsfläche des Körpers herausragen.The invention relates to a device for storing reinforcing steel for connection areas of concrete structures in the form of an elongated, essentially strip-shaped body, in which bending-out connection areas of the reinforcement steel are embedded, the anchoring areas of which protrude from a wide longitudinal surface of the body.

Eine derartige Vorrichtung ist aus der DE-B-2503742 bekannt. Bei der bekannten Vorrichtung sind die Bewehrungsstähle in eine Verwahrungs-Vorrichtung eingebettet, die als streifenförmiger Schaumstoffkörper ausgebildet ist. Wenn ein Verbindungsbereich einer Beton-Konstruktion, etwa eine T-förmige Stoßverbindung zwischen einer bereits fertiggestellten Betonwand und einer rechtwinklig von dieser ausgehenden Betonwand hergestellt werden soll, ist es nach dem Eingießen der Verwahrungs-Vorrichtung in die zuerst fertiggestellte Betonwand erforderlich, die Verbindungsbereiche der Bewehrungsstähle herauszubiegen und dabei den Schaumstoff vollständig zu entfernen. Insbesondere die Bewehrungsstähle selbst müssen vollständig frei von Schaumstoff sein, da andernfalls eine unzureichende Verbindung zwischen Stahl und Beton entsteht. Dies erfordert einigen Arbeitsaufwand, da der Schaumstoff durch die Bewehrungsstähle festgehalten wird und nur in kleinen Teilen herausgekratzt werden kann.Such a device is known from DE-B-2503742. In the known device, the reinforcing steels are embedded in a storage device, which is designed as a strip-shaped foam body. If a connection area of a concrete structure, such as a T-shaped butt joint, is to be made between an already finished concrete wall and a concrete wall that starts at a right angle from it, the connection areas of the reinforcing steels are required after the storage device has been poured into the first completed concrete wall bend out and completely remove the foam. In particular, the reinforcement steels themselves must be completely free of foam, otherwise an inadequate connection between steel and concrete will result. This requires some work, since the foam is held in place by the reinforcing steel and can only be scraped out in small parts.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Verwahrungs-Vorrichtung der eingangs genannten Art zu schaffen, die nach dem Eingießen in eine Beton-Konstruktion einfach und mit geringem Zeitaufwand entfernt werden kann.The invention is therefore based on the object of providing a storage device of the type mentioned at the outset which, after being poured into a concrete structure, can be removed simply and with little expenditure of time.

Diese Aufgabe wird erfindungsgemäß bei einer Verwahrungs-Vorrichtung des Gattungsbegriffes dadurch gelöst, daß der Körper einen in der breiten Längsfläche offenen Unterkasten umfaßt, auf dessen Bodenfläche in Querrichtung in Längsabständen Halteleisten angeordnet sind, die im oberen Bereich im wesentlichen quer zu ihrer Längsrichtung verlaufende Schlitze zur Halterung der Verbindungsbereiche der Bewehrungsstähle aufweisen, und daß der Unterkasten durch einen von den Verankerungsbereichen durchdrungenen Deckel verschließbar ist.This object is achieved in a storage device of the generic term in that the body comprises an open box in the wide longitudinal surface, on the bottom surface of which are arranged in the transverse direction at longitudinal intervals, the slits in the upper region substantially transverse to their longitudinal direction Have mounting of the connection areas of the reinforcing steel, and that the lower box can be closed by a cover penetrated by the anchoring areas.

Die Verwahrungs-Vorrichtung wird also gebildet durch einen offenen, durch eine Deckelkonstruktion verschließbaren Kasten, der im wesentlichen mit einem Handgriff von einer Beton-Konstruktion, die die Verankerungsbereiche der Verbindungsstähle aufnimmt, abgezogen werden kann. Ein weiterer Vorteil besteht darin, daß der Kasten auch als solcher hergestellt und vertrieben werden kann, so daß er zur Aufnahme von unterschiedlichen Bewehrungsstählen verwendet werden oder von Spezialbetrieben erworben werden kann, die lediglich die Bewehrungsstähle biegen und einlegen. Dieses Einlegen ist ein einfacher und sauberer Vorgang. Ein Entfernen von austretendem Schaum an der Verwahrung entfällt.The storage device is thus formed by an open box which can be closed by a lid construction and which can be pulled off essentially with one hand from a concrete construction which receives the anchoring areas of the connecting steels. Another advantage is that the box can also be manufactured and sold as such, so that it can be used to hold different types of reinforcing steel or can be purchased from specialist companies that only bend and insert the reinforcing steel. This loading is a simple and clean process. There is no need to remove any escaping foam from the storage.

Da die Verankerungsbereiche der Bewehrungsstähle bei einer Vorrichtung der vorliegenden Art aus dem Verwahrungs-Streifen austreten, ist es vorzuziehen, die Austrittsbereiche in den Trennlinien zwischen jeweils benachbarten Deckelelementen vorzusehen. Die Deckelelemente können an ihren einander zugewandten Rändern entsprechende Ausnehmungen zur Aufnahme der Bewehrungsstähle aufweisen.Since the anchoring areas of the reinforcement steels emerge from the storage strip in a device of the present type, it is preferable to provide the exit areas in the dividing lines between adjacent cover elements. The cover elements can have corresponding recesses on their mutually facing edges for receiving the reinforcing steel.

Vorzugsweise sind die Schlitze in den Halteleisten, die sich gegenüberliegend an den beiden Enden der Halteleisten befinden, als nur von einer Seite her eintretende Sackschlitze ausgebildet, so daß sie die umgebogenen und herausragenden Verankerungsbereiche der Bewehrungsstähle aufnahmen und abstützen können. In diesem Falle befinden sich die Trennlinien zwischen den Deckelelementen zweckmäßig in den Längsmittellinien der Halteleisten.The slots in the retaining strips, which are located opposite each other at the two ends of the retaining strips, are preferably designed as pocket slots entering from only one side, so that they can receive and support the bent and protruding anchoring areas of the reinforcing steel. In this case, the dividing lines between the cover elements are expediently in the longitudinal center lines of the holding strips.

Die übrigen Schlitze im Mittelbereich der Halteleisten weisen vorzugsweise einen X-förmigen Querschnitt auf und erweitern sich nach beiden Seiten hin von einem engeren Mittelbereich, so daß die Verbindungsbereiche der Bewehrungsstähle, die später herausbezogen werden, in spitzem Winkel zur Längsachse des Streifens über Kreuz verlegt werden können.The remaining slots in the central area of the retaining strips preferably have an X-shaped cross section and widen on both sides from a narrower central area, so that the connecting areas of the reinforcing steel, which will be removed later, are laid at an acute angle to the longitudinal axis of the strip in a criss-cross manner can.

Da die Bewehrungsstähle in den Schlitzen der Halteleisten festgehalten werden müssen, ist es zweckmäßig, die Schlitze im senkrechten Schnitt betrachtet mit Hinterschneidungen, beispielsweise in der Form einer 8 auszubilden, so daß zwei übereinanderliegende Bewehrungsstähle mit einer gewissen Klemmwirkung festgehalten werden können.Since the reinforcing steel must be held in the slots of the retaining strips, it is expedient to form the slots, viewed in the vertical section, with undercuts, for example in the form of an 8, so that two reinforcing steel bars lying one above the other can be held with a certain clamping effect.

Da die Konstruktion aus Halteleisten und in diesen klemmend gehaltenen Bewehrungsstählen in sich verhältnismäßig stabil ist, können der Unterkasten und die Deckelelemente aus dünnem Material in Form von Folien oder Platten bestehen. Die Halteleisten sind mit dem Boden und den Seitenwänden des Unterkastens vorzugsweise verklebt.Since the construction of retaining strips and in these clamped reinforcing steels is relatively stable in itself, the lower box and the cover elements can consist of thin material in the form of foils or plates. The holding strips are preferably glued to the bottom and the side walls of the lower box.

Eine in Fig. 1 gezeigte und insgesamt mit 10 bezeichnete Verwahrungs-Vorrichtung dient zur Aufnahme von Bewehrungsstählen 12, 14, 16, 18, 20, die insgesamt die Form eines U-förmigen Bügels aufweisen und darüber hinaus in der Nähe ihres geschlossenen Endes senkrecht zur Bügelebene abgewinkelt sind. Derartige Bewehrungsstähle dienen zur Verbindung von Bauwerksteilen aus Beton, die in zwei aufeinanderfolgenden Schritten gegossen werden. Bei der Herstellung des ersten dieser Beton-Bauteile wird die geschlossene Verwahrungs-Vorrichtung 10 mit ihrer in Fig.1 1 untenliegenden Oberfläche gegen die Schalung gelegt, so daß die aus der Vorrichtung 10 herausragenden Bereiche der Bewehrungsstähle 12,14,16,18,20, die als Verankerungsbereiche 22 bezeichnet werden sollen, in den Innenraum der Schalung hineinragen und in der Betonmasse verankert werden.A storage device shown in FIG. 1 and designated overall by 10 serves to hold reinforcing steels 12, 14, 16, 18, 20, which overall have the shape of a U-shaped bracket and moreover, in the vicinity of their closed end, perpendicular to Are angled. Such reinforcement steels are used to connect structural parts made of concrete, which are cast in two successive steps. In the manufacture of the first of these concrete components, the closed storage device 10 is placed with its surface lying in FIG. 11 against the formwork, so that the areas of the reinforcing steel 12, 14, 16, 18, 20 protruding from the device 10 , which are to be referred to as anchoring areas 22, protrude into the interior of the formwork and are anchored in the concrete mass.

Nach Entfernen der nicht gezeigten Schaltung wird die Verwahrungs-Vorrichtung 10 aus dem Beton herausgenommen, und die zunächst flach in der Vorrichtung 10 liegenden Bereiche der Bewehrungsstähle, die als Verbindungsbereiche 24 bezeichnet werden können, werden senkrecht aus dem Betonteil herausgebogen. Diese Verbindungsbereiche 24 werden in die Schalung des anschließend gegossenen Betonteils einbezogen, so daß eine Bewehrungs-Verbindung zwischen den beiden Betonteilen entsteht. Nähere Einzelheiten zu der Verwendung der erfindungsgemäßen Vorrichtung sollen später anhand von Fig. 6 bis 8 erläutert werden.After removing the circuit (not shown), the storage device 10 is removed from the concrete, and the regions of the reinforcing steel, which are initially flat in the device 10 and which can be referred to as connection areas 24, are bent vertically out of the concrete part. These connection areas 24 are included in the formwork of the subsequently poured concrete part, so that a reinforcement connection is created between the two concrete parts. Further details on the use of the device according to the invention will be explained later with reference to FIGS. 6 to 8.

Die Vorrichtung 10 umfaßt einen flachen, streifenförmigen Unterkasten 26 mit einem Boden 28, Seitenwänden 30 und 32 und nicht gezeigten Stirnwänden. Im Inneren des Unterkastens 26 befinden sich quer zu dessen Längsrichtung eine Reihe von parallel im Abstand liegende Halteleisten 34, die von oben eintretende, quer zu den Halteleisten verlaufende Schlitze 36 aufweisen. Neben diesen im Längsmittelbereich der Halteleisten 34 liegenden Schlitzen 36 ist an den Enden der Halteleiste auf beiden Seiten jeweils ein Schlitz 38 vorgesehen, der nur von einer Seite her und von oben in die Halteleiste eintritt und als Sackschlitz bezeichnet werden soll. Während sich die langgestreckten, geraden Verbindungsbereiche 24 der Bewehrungsstähle 12, 14, 16, 18, 20 in den im Mittelbereich der Halteleisten vorgesehenen Schlitzen 36 befinden, dienen die äußeren Schlitze 38 zur Aufnahme der abgewinkelten Übergänge zwischen den Verbindungsbereichen 24 und den Verankerungsbereichen 22 der Bewehrungsstähle. Von den Schlitzen 38 aus ragen die Verankerungsbereiche 22 senkrecht zu der Vorrichtung 10 auf und treten nach oben aus dieser aus.The device 10 comprises a flat, strip-shaped lower box 26 with a bottom 28, side walls 30 and 32 and end walls, not shown. In the interior of the lower box 26 there are a number of holding strips 34 which are parallel and spaced apart and have slots 36 which enter from above and run transversely to the holding strips. In addition to these slots 36 located in the longitudinal central region of the retaining strips 34, a slot 38 is provided on both ends of the retaining strip, which only enters the retaining strip from one side and from above and is to be referred to as a pocket slot. While the elongated, straight connecting areas 24 of the reinforcing steels 12, 14, 16, 18, 20 are located in the slots 36 provided in the central area of the retaining strips, the outer slots 38 serve to accommodate the angled transitions between the connecting areas 24 and the anchoring areas 22 of the reinforcing steel . The anchoring areas 22 protrude from the slots 38 perpendicular to the device 10 and emerge from the device 10 upwards.

Der Unterkasten 26 ist verschließbar durch eine Anzahl von Deckelelementen 40, die im wesentlichen in den Längsmittellinien der Halteleisten 34 geteilt sind, so daß jeweils ein Verankerungsbereich 22 der Bewehrungsstähle zwischen zwei Deckelelementen 40 aus der Vorrichtung austreten kann. Wie aus Fig. 1 hervorgeht, sind an den einander zugewandten Rändern der Deckelelemente 40 halbkreisförmige Aussparungen 42, 44 vorgesehen, die sich jeweils zu Kreisen ergänzen und die Aufnahme der Schenkel der Verankerungsbereiche 22 gestatten. Daher ist der Unterkasten 26 durch die Deckelelemente 40 im wesentlichen dicht verschließbar.The lower box 26 can be closed by a number of cover elements 40, which are essentially divided in the longitudinal center lines of the retaining strips 34, so that in each case an anchoring area 22 of the reinforcing steel between two cover elements 40 can emerge from the device. As can be seen from FIG. 1, semicircular recesses 42, 44 are provided on the mutually facing edges of the cover elements 40, which each complement one another to form circles and allow the legs of the anchoring regions 22 to be received. Therefore, the lower box 26 can be closed essentially tightly by the cover elements 40.

Aus Fig. 1 und 2 geht im übrigen hervor, daß an der Unterseite der Deckelelemente Rastzapfen 46, 48 vorgesehen sind, die in entsprechend angeordnete Rastbohrungen 50, 52 in den Halteleisten 34 einrasten und die Deckelelemente in geschlossener Stellung festhalten.1 and 2 also show that locking pins 46, 48 are provided on the underside of the cover elements, which snap into correspondingly arranged locking bores 50, 52 in the retaining strips 34 and hold the cover elements in the closed position.

Gemäß Fig. 3 liegen die Verbindungsbereiche 24 der Bewehrungsstähle in den Schlitzen 36 der Halteleisten 34 in einer spitzwinklig zur Längsachse des Unterkastens 26 verlaufenden Anordnung, so daß die Bewehrungsstähle in verhältnismäßig dichter Folge vorgesehen sein können, ohne sich gegenseitig im Inneren der Verwahrungs-Vorrichtung zu behindern. Damit die Verbindungsbereiche 24 in den Schlitzen 36 über Kreuz verlegt werden können, weisen die Schlitze 36 eine ausreichende Tiefe zur Aufnahme von zwei übereinanderliegenden Verbindungsbereichen 24 auf, wie beispielsweise aus Fig. 2 hervorgeht. Zur Anordnung der Verbindungsbereiche 22 der Bewehrungsstähle über Kreuz weisen die Schlitze 36 gemäß Fig.4 vorzugsweise einen X-förmigen Querschnitt auf, der sich vom Mittelbereich her nach beiden Seiten erweitert.3, the connecting areas 24 of the reinforcing steel lie in the slots 36 of the retaining strips 34 in an arrangement running at an acute angle to the longitudinal axis of the lower box 26, so that the reinforcing steel can be provided in relatively close succession without mutually inside the storage device hinder. So that the connecting areas 24 can be laid crosswise in the slots 36, the slots 36 have a sufficient depth to accommodate two superimposed connecting areas 24, as can be seen, for example, from FIG. 2. To arrange the connection areas 22 of the reinforcing steel crosswise, the slots 36 according to FIG. 4 preferably have an X-shaped cross section, which widens from the central area to both sides.

Die äußeren Schlitze 38, die zur Aufnahme der abgewinkelten Übergangsbereiche zwischen den Verbindungsbereichen 24 und den Verankerungsbereichen 22 dienen, können im waagerechten Querschnitt einen hinterschnittenen, inneren Haltebereich 54 und einen trichterförmig erweiterten Öffnungsbereich 56 umfassen. Der Haltebereich 54 bewirkt ein Festklemmen der aufragenden Schenkel des Verankerungsbereichs 22. Die trichterförmigen Öffnungsbereiche 56 gestatten einen Austritt der Verbindungsbereiche 24 in spitzem Winkel zur Längsmittellinie des Unterkastens 26.The outer slots 38, which serve to receive the angled transition areas between the connecting areas 24 and the anchoring areas 22, can include an undercut inner holding area 54 and a funnel-shaped opening area 56 in the horizontal cross section. The holding area 54 causes the protruding legs of the anchoring area 22 to be clamped in place. The funnel-shaped opening areas 56 allow the connection areas 24 to exit at an acute angle to the longitudinal center line of the lower box 26.

Zum Festklemmen der Verbindungsbereiche 24 der Bewehrungsstähle weisen die Schlitze 36 und 38 gemäß Fig. 2 im senkrechten Schnitt ebenfalls Hinterschneidungen auf, so daß sich etwa gemäß Fig. 2 ein 8förmiges Schnittbild ergeben kann, sofern zwei Verbindungsbereiche 24 übereinander verlegt werden sollen.To clamp the connecting areas 24 of the reinforcing steel, the slots 36 and 38 according to FIG. 2 also have undercuts in the vertical section, so that an 8-shaped sectional view can result, for example according to FIG. 2, provided that two connecting areas 24 are to be laid one above the other.

In Fig. 2 und 4 sind im übrigen Trennschlitze 58, 60 angedeutet, die quer zu den Halteleisten 34 von oben her in diese eintreten und eine gewisse elastische Verformung der als Klemmbacken wirkenden Teile der Halteleisten 34 gestatten.2 and 4, separation slots 58, 60 are also indicated, which enter the holding strips 34 from above and allow a certain elastic deformation of the parts of the holding strips 34 which act as clamping jaws.

Die Halteleisten 34 können aus elastischem Kunststoff bestehen, und die Schlitze 36, 38 können in bezug auf die Abmessungen der Bewehrungsstähle derart bemessen sein, daß die Bewehrungsstähle mit einem gewissen Druck in die Schlitze eingedrückt werden müssen und durch diese Klemmen gehalten werden.The retaining strips 34 can be made of elastic plastic, and the slots 36, 38 can with respect to the dimensions of the Reinforcing steels must be dimensioned such that the reinforcing steels must be pressed into the slots with a certain pressure and are held by these clamps.

Fig. 4 zeigt eine Seitenansicht der Vorrichtung 10 mit aus dieser herausragenden Verankerungsbereichen 22 der Bewehrungsstähle. Es ist erkennbar, daß die hier nicht näher bezeichneten Verbindungsbereiche der Bewehrungsstähle in zwei Lagen übereinander in dem Unterkasten 26 liegen.FIG. 4 shows a side view of the device 10 with the anchoring regions 22 of the reinforcing steels protruding therefrom. It can be seen that the connecting areas of the reinforcing steels, not described here in more detail, lie in two layers one above the other in the lower box 26.

Anschließend soll unter Bezugnahme auf Fig. 4 bis 8 noch einmal auf die Verwendung der erfindungsgemäßen Vorrichtung eingegangen werden. Als Beispiel soll eine T-förmige Stoßverbindung zwischen zwei Betonwänden dienen, die in zwei aufeinanderfolgenden Schritten gegossen werden. Zunächst wird eine der Betonwände gegossen, die mit 62 bezeichnet ist. Während des Vergießens liegt innerhalb einer mit 64, 66 bezeichneten Schalung in senkrechter Anordnung die erfindungsgemäße Vorrichtung 10, wobei die Bodenfläche der Vorrichtung gegen eine der Schalungen 66 anliegt. In dieser Position ragen die Verankerungsbereiche 22 der Bewehrungsstähle in die Betonmatrix hinein, so daß sie in der Betonwand 62verankert werden.The use of the device according to the invention will then be discussed again with reference to FIGS. 4 to 8. An example is a T-shaped butt joint between two concrete walls that are poured in two successive steps. First, one of the concrete walls, which is labeled 62, is poured. During the casting, the device 10 according to the invention lies within a formwork designated 64, 66 in a vertical arrangement, the bottom surface of the device resting against one of the formworks 66. In this position, the anchoring areas 22 of the reinforcing steels protrude into the concrete matrix, so that they are anchored in the concrete wall 62.

Nach Entfernen der Schaltung 66 ist der Boden der Vorrichtung 10 von außen zugänglich. Da die Halteleisten 34 mit den jeweiligen Schlitzen 36, 38 die Bewehrungsstähle nur von der Bodenseite her umgreifen, kann zumeist die gesamte Verwahrungs-Vorrichtung von den eingegossenen Verankerungsbereichen 22 und den Verbindungsbereichen 24 mit einem Handgriff abgezogen werden. Anschließend werden die Verbindungsbereiche 24 in üblicher Weise senkrecht aus der Betonwand 62 herausgebogen, wie im oberen Teil von Fig. 7 und 8 veranschaulicht ist, und nach Herstellung einer entsprechenden Schalung kann die anschließende Betonwand gegossen werden.After removing the circuit 66, the bottom of the device 10 is accessible from the outside. Since the retaining strips 34 with the respective slots 36, 38 only grip the reinforcement bars from the bottom side, the entire storage device can usually be removed from the cast-in anchoring areas 22 and the connecting areas 24 with one hand. The connecting areas 24 are then bent out of the concrete wall 62 vertically in the usual manner, as illustrated in the upper part of FIGS. 7 and 8, and after the appropriate formwork has been produced, the subsequent concrete wall can be poured.

Da die Verbindungsbereiche 24 während des Gießens der ersten Betonwand 62 gemäß der unteren Darstellung in Fig. innerhalb der Vorrichtung 10 und damit innerhalb der Schalung 66 liegen, ist es nicht notwendig, die zumeist wiederzuverwendende Schalung 66 durch Bohrungen zu zerstören.Since the connection areas 24 during the pouring of the first concrete wall 62, as shown in the lower illustration in FIG., Lie within the device 10 and thus within the formwork 66, it is not necessary to destroy the mostly reusable formwork 66 by drilling.

Es wurde bereits darauf hingewiesen, daß der Unterkasten und die Deckelelemente aus dünnem folienartigen Kunststoffmaterial bestehen können, da die Anordnung aus den Halteleisten 34 und den in diese eingeklemmten Bewehrungsstählen eine in sich ausreichend tragende Konstruktion ergeben.It has already been pointed out that the lower box and the cover elements can consist of thin film-like plastic material, since the arrangement of the holding strips 34 and the reinforcing steel clamped in them results in a sufficiently load-bearing construction.

Im Rahmen der zuvor erläuterten Ausführungsform wurden Halteleisten 34 beschrieben, die als massive Leisten mit Schlitzen oder Kerben ausgebildet waren. Eine derartige Ausführung ist jedoch nicht notwendig. Es kommen auch Konstruktionen aus Draht, Stahlband od. dgl. in Betracht, die zwar den Konturen der Schlitze folgen und somit eine Aufnahme der Bewehrungsstähle ermöglichen, im übrigen jedoch nicht massiv sind. Wesentlich sind lediglich quer zur Längsrichtung des Unterkastens gerichtete Halteorgane, die ein Einklemmen der Bewehrungsstähle ermöglichen und diese zugleich gegeneinander auf Abstand und in der gewünschten Position halten.In the context of the previously described embodiment, retaining strips 34 were described which were designed as solid strips with slots or notches. However, such an implementation is not necessary. There are also constructions made of wire, steel strip or the like, which, although they follow the contours of the slots and thus allow the reinforcement steels to be accommodated, are otherwise not massive. What is essential is only holding members directed transversely to the longitudinal direction of the lower box, which enable the reinforcing steels to be clamped in and at the same time keep them at a distance from one another and in the desired position.

Auch der Deckel gestattet verschiedene Abwandlungen. Wesentlich ist lediglich, daß der Deckel einen Durchgang der austretenden Verankerungsbereiche der Bewehrungsstähle ermöglicht. Im übrigen kann der Deckel als geschlossene Einheit mit Schlitzen und/oder Ausschnitten zur Aufnahme der Verankerungsbereiche oder in Form von einzelnen Elementen aufgelegt werden. Er kann ggf. auch scharnierartig mit einer oberen freien Längskante des Unterkastens verbunden sein, wie es in dem beschriebenen Beispiel der Fall ist. Im übrigen kann sich die Gestaltung des Deckels auch nach der Form der Verankerungsbereiche richten, die nicht die zuvor erläuterte U-Form aufweisen müssen, sondern jede beliebige, zur Verankerung geeignete Biegeform aufweisen können und auch nicht bügelförmig in Verbindung stehen müssen.The lid also allows various modifications. It is only essential that the cover allows passage of the emerging anchoring areas of the reinforcing steel. In addition, the cover can be placed as a closed unit with slots and / or cutouts for receiving the anchoring areas or in the form of individual elements. If necessary, it can also be connected in a hinge-like manner to an upper free longitudinal edge of the lower box, as is the case in the example described. Otherwise, the design of the cover can also be based on the shape of the anchoring regions, which do not have to have the U-shape explained above, but can have any bending shape suitable for anchoring and also do not have to be connected in a bow-shaped manner.

Anstelle der beschriebenen Rastzapfen können andere Verschlußorgane oder Verschlußverfahren eingesetzt werden. Im Falle der Verwendung einer Kunststoffolie zur Herstellung des Kastens kann der Deckel durch Punktschweißen verschlossen werden. Es können auch Klebestreifen, Klettenverschlüsse od. dgl. verwendet werden.Instead of the locking pins described, other locking members or locking methods can be used. If a plastic film is used to produce the box, the lid can be closed by spot welding. Adhesive strips, Velcro fasteners or the like can also be used.
