Description

Die Erfindung betrifft ein Verfahren zum Einschalen von Decken, bei dem eine Anzahl von Stützen in Abständen zueinander aufgestellt werden, wobei jeweils eine Teilanzahl in einer Linie fluchtend miteinander anzuordnen ist, auf die dann jeweils Längsträger und auf diese Querträger aufgelegt werden, so daß die Querträger jeweils zumindest auf zwei Längsträgern aufliegen, und schließlich Schalungsplatten auf die Querträger aufgebracht werden. Des weiteren betrifft die Erfindung ein Deckenschalungssystem mit einer Anzahl Stützen, Längs- und Querträgern und Schalungsplatten.The invention relates to a method for shuttering ceilings, in which a number of supports are placed at intervals from one another, with a number of parts in each case being arranged in alignment with one another, onto which the longitudinal members and these cross members are then placed, so that the cross members each rest on at least two side members, and finally formwork panels are applied to the cross members. Furthermore, the invention relates to a slab formwork system with a number of supports, longitudinal and cross members and formwork panels.

Zur Herstellung von Decken aus Beton ist ein Verfahren der eingangs genannten Art seit langem bekannt. Hierbei werden Stützen in zuvor anhand von Berechnungstabellen bestimmten Aufstellpunkten aufgestellt. Darauf werden Längsträger aufgelegt, deren Abstände ebenfalls aus Berechnungstabellen zu entnehmen sind, so daß diese im wesentlichen parallel zueinander liegen. Auf die Längsträger werden wiederum im wesentlichen senkrecht hierzu in wiederum in Berechnungstabellen festgelegten Abständen Querträger parallel zueinander gelegt. Schließlich werden auf die Querträger Schalungsplatten so aufgelegt, daß deren größere Seitenlänge senkrecht zu der Längsrichtung der Querträger zum liegen kommen.A process of the type mentioned at the outset has long been known for the production of concrete ceilings. Here, columns are erected at set-up points previously determined on the basis of calculation tables. Longitudinal girders are placed thereon, the spacing of which can also be found in calculation tables, so that they lie essentially parallel to one another. Cross members are again placed parallel to one another on the longitudinal members, essentially perpendicularly thereto, at intervals which are again determined in calculation tables. Finally, formwork panels are placed on the cross beams in such a way that their longer sides come to lie perpendicular to the longitudinal direction of the cross beams.

Es besteht jedoch bei diesem bekannten Verfahren das Problem, daß die Aufstellpunkte der Stützen, die Abstände der Längssowie der Querträger zueinander mittels den relativ komplizierten Berechnungstabellen in Abhängigkeit von der zu betonierenden Deckenstärke und der verwendeten einzelnen Deckenschalungselemente bestimmt werden müssen. Unter Deckenschalungselementen werden hier die Stützen, Längs- und Querträger sowie die Schalungsplatten verstanden.However, there is the problem with this known method that the installation points of the supports, the spacing of the longitudinal and the cross members from one another by means of the relative complicated calculation tables must be determined depending on the slab thickness to be concreted and the individual slab formwork elements used. Here slab formwork elements are understood to be the supports, longitudinal and cross beams as well as the formwork panels.

Da auf den Baustellen oftmals nicht die erforderliche Sorgfaltspflicht beim Ablesen der Berechnungstabellen eingehalten wird bzw. die Arbeiter nicht die hierfür erforderliche Qualifikation aufweisen, besteht die Gefahr, daß möglicherweise die einzuhaltenden Maximalabstände überschritten werden, was eine ungenügende Abstützung beim Betonieren der Decke mit möglicher Einsturzgefahr zur Folge haben kann. Des weiteren muß auf der Baustelle gemäß den Berechnungstabellen die Art der Stütze, der Quer- und Längsträger sowie der Schalungsplatten berücksichtigt werden, was zu einer Anzahl von Berechnungstabellen und einer weiteren Verkomplizierung der Bestimmung bzw. Festlegung der Abstände der einzelnen Elemente zueinander führt.Since the required due diligence is often not observed when reading the calculation tables on the construction sites or the workers do not have the necessary qualifications, there is a risk that the maximum distances to be observed may be exceeded, which is insufficient support when concreting the ceiling with a possible risk of collapse Can have consequences. Furthermore, the type of support, the transverse and longitudinal beams and the formwork panels must be taken into account on the construction site in accordance with the calculation tables, which leads to a number of calculation tables and a further complication of the determination or determination of the distances of the individual elements from one another.

Das der Erfindung zugrundeliegende technische Problem besteht darin, ein Verfahren zum Einschalen von Decken zu schaffen, bei dem unabhängig von der zu betonierenden Deckenstärke - bis zu einer maximalen Deckenstärke - ein Überschreiten der maximalen Abstände der einzelnen Elemente zueinander vermieden oder sogar ausgeschlossen wird. Des weiteren besteht ein der Erfindung zugrundeliegendes technisches Problem darin, ein zur Durchführung des Verfahrens geeignetes Deckenschalungssystem zu schaffen.The technical problem on which the invention is based is to provide a method for shuttering ceilings in which, regardless of the ceiling thickness to be concreted - up to a maximum ceiling thickness - exceeding the maximum distances of the individual elements from one another is avoided or even excluded. Furthermore, a technical problem on which the invention is based is to create a slab formwork system suitable for carrying out the method.

Das der Erfindung zugrundeliegende technische Problem wird dadurch gelöst, daß die Stützen, Längs- und Querträger derart aufgestellt werden, daß die jeweiligen Abstände der Quer- und Längsträger sowie der Stützen zueinander für alle zu betonierenden Deckenstärken bis zu einer vorgegebenen Deckenstärke anhand von optisch wirkenden und/oder mechanisch angebrachten, festen Aufstellhilfen an den Längs- und Querträgern und/oder Stützen und/oder Schalungsplatten eingehalten werden.The technical problem underlying the invention is solved in that the supports, longitudinal and transverse beams are set up in such a way that the respective distances between the transverse and longitudinal beams and the supports are mutually related for all ceiling thicknesses to be concreted up to a predetermined Ceiling thickness on the side and cross members and / or supports and / or formwork panels are observed using optically acting and / or mechanically attached, fixed installation aids.

Des weiteren wird ein Deckenschalungssystem mit Stützen, Schalungsplatten, Quer- und Längsträger zur Durchführung des Verfahrens bereitgestellt, die jeweils zumindest in Einbaulage auf der unteren Seite parallel zueinander, in gleichen Abständen liegende optisch und/oder mechanisch wirksame, fest angebrachte Aufstellhilfen aufweisen.Furthermore, a slab formwork system is provided with supports, formwork panels, cross members and longitudinal beams for carrying out the method, each of which has, at least in the installed position on the lower side parallel to one another and at equal intervals, optically and / or mechanically effective, fixed installation aids.

Der Erfindung liegt der Gedanke zugrunde, das Einschalen von Decken derart zu vereinfachen, daß keine komplizierten Berechungstabellen zum Bestimmen der Abstände der einzelnen Elemente zueinander mehr notwendig sind. Erfindungsgemäß kann erstmals nun unabhängig von der zu betonierenden Deckenstärke - bis natürlich zu einer maximalen Deckenstärke, die durch die maximale Tragkraft der Elemente vorgegeben ist - das Aufstellen der einzelnen Elemente standardisiert werden, indem durch die optisch und/oder mechanisch wirkenden, fest angebrachten Aufstellhilfen an den Längs-, Querträgern und/oder Schalungsplatten die einzuhaltenden Abstände eindeutig vorgegeben sind. Dadurch wird beim Aufstellen der Deckenschalung ein Überschreiten der maximalen Abstände, wodurch eine latente Einsturzgefahr hervorgerufen wird, stark verringert bzw. verhindert. Des weiteren ist es bei dem erfindungsgemäßen Deckenschalungssystem erstmals möglich, in aufgestelltem Zustand die vorgeschriebenen Abstände problemlos zu kontrollieren. Denn anhhand der Aufstellhilfen kann ein nicht korrekt plaziertes Element sofort ohne weitere Hilfsmittel erkannt werden. Beim Stand der Technik hingegen mußten sich probenhaft - was wiederum eine gewisse Unsicherheit bedingt - mit einem Metermaß die einzelnen Abstände kontrolliert werden. Dies kann nun durch einen einfachen Kontrollblick ersetzt werden, was wiederum einen großen Zeitgewinn und eine größere Sicherheit zur Folge hat.The invention is based on the idea of simplifying the shuttering of ceilings in such a way that complicated calculation tables for determining the distances of the individual elements from one another are no longer necessary. According to the invention, the installation of the individual elements can now be standardized for the first time regardless of the ceiling thickness to be concreted - up to a maximum ceiling thickness, of course, which is predetermined by the maximum load-bearing capacity of the elements - by means of the optically and / or mechanically acting, fixed installation aids the distances to be maintained are clearly specified for the longitudinal, cross beams and / or formwork panels. As a result, when the ceiling formwork is erected, exceeding the maximum distances, which creates a latent risk of collapse, is greatly reduced or prevented. Furthermore, with the slab formwork system according to the invention, it is possible for the first time to easily check the prescribed distances when set up. An incorrectly placed element can be recognized immediately without any additional aids using the installation aids. In the prior art, however, the individual distances had to be checked on a trial basis - which in turn caused a certain degree of uncertainty - with a meter. This can now be done by a simple control gaze can be replaced, which in turn saves a lot of time and increases security.

Durch das erfindungsgemäße Verfahren bzw. das erfindungsgemäße Deckenschalungssystem wird die Sicherheit der Deckenschalung stark erhöht. Zudem ist es ein großer Vorteil des erfindungsgemäßen Verfahrens, daß das Aufstellen auch mit einer großen Zeitersparnis einhergeht. Zwar wird bei dem erfindungsgemäßen Verfahren bei einer sehr geringen zu betonierenden Deckenstärke der maximal mögliche Abstand der einzelnen Elemente zueinander unterschritten und somit mehr Material verwendetals unbedingt notwendig wäre, jedoch steht dieser zusätzliche Materialaufwand und dessen Kosten in keinem Verhältnis zu der gewonnenen Zeitersparnis beim Aufstellen der Deckenschalung. Denn die zusätzlichen Kosten durch den höheren Materialaufwand sind um ein Vielfaches geringer als die durch den geringeren Zeitaufwand gewonnene Kostenersparnis. Anhand von vielen praktisch nachgerechneten Deckenschalungen ist nachgewiesen, daß sich der Materialaufwand bei Deckenstärken bis zu etwa 30 cm lediglich um im Durchschnitt 5% erhöht.The safety of the slab formwork is greatly increased by the method and slab formwork system according to the invention. In addition, it is a great advantage of the method according to the invention that the erection is also associated with a great saving of time. Although in the method according to the invention the maximum possible distance of the individual elements from one another is undershot with a very small slab thickness to be concreted and thus more material is used than would be absolutely necessary, this additional material expenditure and its costs are in no relation to the time saved when setting up the slab formwork . This is because the additional costs due to the higher material expenditure are many times smaller than the cost savings gained through the reduced expenditure of time. On the basis of many practically recalculated slab formworks, it has been proven that the material expenditure for slab thicknesses up to approx. 30 cm increases by only 5% on average.

Durch das erfingungsgemäße Verfahren bzw. Deckenschalungssystem ist also ein beträchtlicher Gewinn an Einfachheit, Schnelligkeit und Sicherheit gegenüber dem bekannten Verfahren erreicht.The method or slab formwork system according to the invention thus achieves a considerable gain in simplicity, speed and safety compared to the known method.

Vorteilhafterweise werden die jeweiligen Abstände der Quer- und Längsträger sowie der Stützen zueinander entsprechend der maximal zu betonierenden Deckenstärke, die unter Berücksichtigung der Geometrie und Werkstoffdaten der Schalungsplatten, Quer- und Längsträger sowie der Stützen berechnet wird, festgelegt. Denn hierdurch wird bis zu einer maximalen Deckenstärke die volle Tragfähigkeit der einzelnen Schalungssystemelemente gewährleistet.Advantageously, the respective distances between the crossbeams and longitudinal beams and the supports from one another are determined in accordance with the maximum slab thickness to be concreted, which is calculated taking into account the geometry and material data of the formwork panels, transverse and longitudinal beams and the supports. This ensures the full load-bearing capacity of the individual formwork system elements up to a maximum ceiling thickness.

Sehr vorteilhaft ist es, daß das Aufstellen der Schalungselemente anhand von jeweils auf zumindest in Einbaulage unteren Seite der Quer- und Längsträger und/oder der Schalungsplatten angebrachten Aufstellhilfen erfolgt, wodurch für einen Arbeiter die erforderlichen Abstände bereits eindeutig vorbestimmt sind.It is very advantageous that the formwork elements are set up on the basis of installation aids which are respectively mounted on the lower side of the cross members and longitudinal members and / or the formwork panels, at least in the installed position, as a result of which the necessary clearances are already clearly predetermined for a worker.

Sehr einfach und kostengünstig aufzubringen sind farbige, parallel zueinanderliegende Markierungen auf den Schalungselementen. Zudem schwächen derartige Markierungen bzw. Aufstellhilfen die einzelnen Elemente des Systems nicht.Colored, parallel markings on the formwork elements are very easy and inexpensive to apply. In addition, such markings or installation aids do not weaken the individual elements of the system.

Durch erfindungsgemäß abwechselnd farbige Markierungen wird das Aufstellen der Schalungselemente und deren gegenseitige Zuordnung sehr vorteilhaft vereinfacht, da durch die eindeutige Kennzeichnung zur Auflage der Elemente fehlerhafte Abstände mit höchster Wahrscheinlichkeit ausgeschlossen wird. So können diese z.B. in einem Abstand von 1 m gleich sein. Das heißt, daß z.B. von der Stirnseite eines Quer- oder Längsträgers aus alle 0.5m eine Aufstellhilfelinien angebracht ist, die abwechselnd eine andere Farbe, Gestalt oder dergleichen aufweisen.By means of alternately colored markings according to the invention, the erection of the formwork elements and their mutual assignment is very advantageously simplified, since the clear identification for the support of the elements excludes incorrect distances with the highest probability. So they can e.g. be the same at a distance of 1 m. That is, e.g. From the front of a cross member or side member, an installation aid line is attached every 0.5m, which alternately has a different color, shape or the like.

Besonders vorteilhaft ist es, wenn an den Stützen, Längs- wie auch an den Querträgern und eventuell auch an den Schalungsplatten in den erforderlichen Abständen mechanische Aufstellhilfen angebracht sind, in die die jeweils aufeinanderliegenden Schalungselemente ineinandergreifen. Hierdurch wird ein Unterschreiten der vorbestimmten Abstände mit höchster Zuverlässigkeit vermieden. So ist es z.B. denkbar, daß die Stützen in ihrem Tragkopf zur Aufnahme eines Längsträgers eine kleine Erhebung aufweisen, die in eine entsprechend angepaßte Vertiefung im Längsträger einpaßbar ist. Dadurch wird ein Aufstellen der Träger in einem unerlaubten Abstand erst gar nicht ermöglicht. Die anderen Schalungselemente weisen dabei ebenso auf Ober- und Unterseite zueinander passende Erhebungen oder Vertiefungen auf. Es besteht zudem die Möglichkeit optisch und mechanisch wirkende Aufstellhilfen an den Schalungselementen zu kombinieren. So ist es z.B. möglich auf den Schalungsplatten optische Aufstellhilfen anzubringen und die restlichen Elemente mit mechanischen auszustatten.It is particularly advantageous if, at the required intervals, mechanical installation aids are attached to the supports, longitudinal as well as to the cross beams and possibly also to the formwork panels, into which the formwork elements lying one on top of the other interlock. This avoids falling below the predetermined distances with maximum reliability. For example, it is conceivable that the supports have a small elevation in their support head for receiving a side member, which elevation can be fitted into a correspondingly adapted recess in the side member. This will allow the beams to be set up in one unauthorized distance is not possible at all. The other formwork elements also have mating elevations or depressions on the top and bottom. There is also the option of combining optically and mechanically effective installation aids on the formwork elements. For example, it is possible to install optical installation aids on the formwork panels and to equip the remaining elements with mechanical ones.

Die Verwendung von Stützen, die in ihrer Höhe verstellbar sind und unabhängig von der eingestellten Höhe immer die gleiche Tragkraft haben, ist bei dem erfindungsgemäßen Deckenschalungssystem sehr vorteilhaft, da hierdurch unabhängig von der Höhe über dem Boden, in der die Decke eingeschalt werden soll, immer die gleichen erfindungsgemäßen Längs- und Querträger sowie Schalungsplatten mit den jeweils darauf angebrachten optisch und/oder mechanisch wirksamen, festen Aufstellhilfen verwendet werden können.The use of supports that are adjustable in height and always have the same load-bearing capacity regardless of the set height is very advantageous in the slab formwork system according to the invention, since this means that regardless of the height above the floor at which the slab is to be switched on, always the same longitudinal and cross members according to the invention and formwork panels with the optically and / or mechanically effective, fixed installation aids attached to them can be used.

Sehr vorteilhaft sind kegelförmige Vertiefungen bzw. entsprechende Erhebungen an den einzelnen Deckenschalungselementen, da damit automatisch die aufeinanderliegenden Elemente mittig zentriert werden.Conical depressions or corresponding elevations on the individual slab formwork elements are very advantageous, since the elements lying on top of one another are thereby automatically centered in the center.

In der Fig. 1 ist ein Deckenschalungssystem gemäß einem ersten Ausführungsbeispiel der Erfindung in aufgestelltem Zustand gezeigt. Stützen 1, die einen ausklappbaren Fuß aufweisen, sind in Abständen voneinander aufgestellt. Dabei bilden jeweils eine bestimmte Anzahl der Stützen 1 eine Auflage für Längsträger 6, die in Halteköpfe 12 der einzelnen Stützen 1 aufgelegt sind. Auf diesen Längsträgern 6 sind senkrecht dazu Querträger 3 aufgelegt. Die Querträger 3 liegen dabei jeweils parallel zueinander, im wesentlichen senkrecht zu den Längsträgern 6, auf den Längsträgern 6 auf. Bei dem in Fig. 1 dargestellten Zustand sind teilweise Schalungsplatten 4 auf den Querträgern 3 aufgelegt, so daß die längere Seite der Schalungsplatten 4 senkrecht zu der Längsachse der Querträger 3 liegt.1 shows a slab formwork system according to a first exemplary embodiment of the invention in the erected state. Supports 1, which have a fold-out foot, are set up at intervals from one another. A certain number of supports 1 each form one Support for longitudinal beams 6, which are placed in holding heads 12 of the individual supports 1. Cross members 3 are placed perpendicularly to these longitudinal members 6. The cross members 3 each lie parallel to one another, essentially perpendicular to the side members 6, on the side members 6. In the state shown in Fig. 1, formwork panels 4 are partially placed on the cross members 3, so that the longer side of the formwork panels 4 is perpendicular to the longitudinal axis of the cross member 3.

Zwischen den Stützen 1 sind jeweils noch Zwischenstützen 2 angeordnet, die ebenso die Längsträger 6 unterstützen.Between the supports 1 there are still intermediate supports 2, which also support the side members 6.

Die Längsträger 6 weisen bei diesem Ausführungsbeispiel an der Unterseite der Gurte farbliche Aufstellhilfen auf, die in dieser Darstellung nicht ersichtlich sind. Die Stützen 1 und 2 sind jeweils an den durch die farblichen Aufstellhilfen gekennzeichneten Positionen aufgestellt.In this exemplary embodiment, the longitudinal beams 6 have colored installation aids on the underside of the belts, which are not visible in this illustration. The supports 1 and 2 are each set up at the positions indicated by the colored installation aids.

Die Querträger 3 weisen in Abständen optisch wirksame, farbige Aufstellhilfen 31 an vorbestimmten Positionen auf. Die Aufstellhilfen 31 an den Querträgern 3 können z.B. von den Stirnseiten aus in 0,5 m -Abständen angebracht sein, wobei sich unterschiedlich optisch wirkende Aufstellhilfen 31 abwechseln. Die Längsträger 6 sind dann in vorbestimmten Positionen an den Aufstellhilfen 31 anzuordnen. So wie bei diesem Ausführungsbeispiel, bei dem ein Längsträger 6 an der ersten Aufstellhilfe 31 der Querträger 3 parallel zu einer Wand 5 anzuordnen ist, an der die Querträger 3 mit ihren Stirnseiten anliegen. Der parallel zu diesem nächst der Wand 5 angeordneten Längsträger 6 ist dann in einem Abstand von vier Aufstellhilfen 31 anzuordnen.The cross members 3 have optically effective, colored mounting aids 31 at predetermined positions at intervals. The installation aids 31 on the cross beams 3 can e.g. be attached from the end faces at 0.5 m intervals, with different optically acting installation aids 31 alternating. The longitudinal members 6 are then to be arranged in predetermined positions on the installation aids 31. As in this exemplary embodiment, in which a longitudinal member 6 on the first installation aid 31 of the cross member 3 is to be arranged parallel to a wall 5 against which the cross members 3 rest with their end faces. The longitudinal beam 6 arranged parallel to this next to the wall 5 is then to be arranged at a distance of four installation aids 31.

In der Fig. 2 ist eine Seitenansicht auf eine aufgestellte erfindungsgemäße Deckenschalung, bei der insbesondere farblich abgesetzte Aufstellhilfen 63 an den Längsträgern 6 in regelmäßigen Abständen voneinander ersichtlich sind. Auf den Längsträgern 6 liegen parallel zueinander angeordnete Querträger 3 auf, auf denen wiederum Schalungsplatten 4 angeordnet sind. Darüber ist die bereits betonierte Decke 7 ersichtlich. Die Längsträger 6 sind dabei an den durch die farbigen bzw. optisch wirkenden Aufstellhilfen 63 durch Stützen 1 und 2 unterstützt.In Fig. 2 is a side view of an erected slab formwork according to the invention, in particular Colored set-up aids 63 on the side members 6 can be seen at regular intervals from one another. On the longitudinal beams 6 there are transverse beams 3 arranged parallel to one another, on which in turn formwork panels 4 are arranged. The already concreted ceiling 7 can be seen above this. The side members 6 are supported on the by the colored or optically acting installation aids 63 by supports 1 and 2.

Bei Baugleichheit der Quer- 3 und Längsträger 6 sind die optisch wirkenden Aufstellhilfen 31, 63 in regelmäßigen Abständen an dem Quer- 3 bzw. Längsträger 6 angebracht.If the transverse beams 3 and longitudinal beams 6 are identical, the optically acting installation aids 31, 63 are attached to the transverse beams 3 and longitudinal beams 6 at regular intervals.

So beträgt bei diesem Ausführungsbeispiel der Abstand der Stützen 1, 2 am Längsträger 6 zwei Teileinheiten, d.h. an jeder zweiten Aufstellhilfe 63 ist der Längsträger 6 durch eine Stütze 1 oder 2 zu unterstützen. Der Abstand der Längsträger 6 voneinander beträgt bei diesem Ausführungsbeispiel vier Teileinheiten, was bedeutet, daß bezüglich der Aufstellhilfen 31 an den Querträgern 3 die Längsträger 6 an jeder vierten Aufstellhilfe 31 eines Querträgers 3 zueinander angeordnet sind. Der Trägerabstand der Querträger 3 beträgt bei diesem Ausführungsbeispiel in etwa 0,5 m, das bedeutet, daß an einer Schalungsplatte 4 Aufstellhilfen auf der Unterseite der Schalungsplatten angebracht sind, wie noch in der Fig. 3 erläutert wird. Der Tragarm, d.h. der Abstand der Unterstützung an einem Längs- 6 und Querträger 3 beträgt maximal den Abstand einer Aufstellhilfe 31 bzw. 63.In this embodiment, the distance between the supports 1, 2 on the side member 6 is two sub-units, i.e. on every second set-up aid 63, the side member 6 is to be supported by a support 1 or 2. The spacing of the longitudinal beams 6 from one another in this exemplary embodiment is four sub-units, which means that with respect to the installation aids 31 on the cross beams 3, the longitudinal beams 6 are arranged on every fourth installation aid 31 of a cross beam 3. The beam spacing of the cross beams 3 in this embodiment is approximately 0.5 m, which means that 4 mounting aids are attached to a formwork panel on the underside of the formwork panels, as will be explained in FIG. 3. The support arm, i.e. the distance between the support on a longitudinal 6 and cross member 3 is at most the distance between a set-up aid 31 and 63.

Die Fig. 3 zeigt die Unterseite einer Schalungsplatte 4 mit darauf in Abständen zueinander parallel angeordneten, optisch wirkenden Aufstellhilfen 41, die in eindeutiger Art und Weise zum Positionieren der Querträger 3 dienen. Die Aufstellhilfen 41 können wiederum optisch wirkende und mechanisch aufgebrachte Markierungen sein, die auch bei härterem Baubetrieb und bei Verschmutzung durch aufgebrachten Beton sehr beständig sind.3 shows the underside of a formwork panel 4 with optically acting set-up aids 41 arranged thereon at parallel intervals, which serve in a clear manner for positioning the crossbeams 3. The installation aids 41 can in turn be optically acting and mechanical applied markings, which are very stable even in tough construction and when contaminated by applied concrete.

Dies trifft auch für die Aufstellhilfen 31, 63 an Quer- 3 bzw. Längsträgern 6 zu, die zum Beispiel durch Einbrennen in das Holz der Quer- 3 und Längsträger 6 erzeugt werden können. Es können aber auch z.B. extra angebrachte, gegen mechanische Einwirkung widerstandsfähige Markierungsplatten oder dergleichen die gleiche Funktion erfüllen.This also applies to the installation aids 31, 63 on the cross members 3 or longitudinal members 6, which can be produced, for example, by burning into the wood of the cross members 3 and longitudinal members 6. However, e.g. specially attached marking plates or the like which are resistant to mechanical influences fulfill the same function.

In der Fig. 4 ist nochmals die Seitenansicht eines Querträgers 3 mit darauf in regelmäßigen Abständen angebrachten Aufstellhilfen 31 gezeigt. Bei diesem Ausführungsbeispiel laufen die Aufstellhilfen 31 in einem Teilbereich der Außenwandung des Querträgers 3 umlaufend um. Es ist jedoch ebenso möglich, dies nur auf der Unterseite der Gurte des Querträgers 3 anzubringen. Die in Fig. 4 gezeigte Darstellung trifft aber auch ebenso auf einen Längsträger 6 zu.4 again shows the side view of a cross member 3 with mounting aids 31 mounted thereon at regular intervals. In this embodiment, the set-up aids 31 run all around in a partial area of the outer wall of the cross member 3. However, it is also possible to do this only on the underside of the straps of the cross member 3. However, the illustration shown in FIG. 4 also applies to a longitudinal beam 6.

In der Fig. 5 ist ein Querschnitt durch einen Querträger 3 und einen darunterliegenden Längsträger 6 gemäß einem weiteren Ausführungsbeispiel der Erfindung gezeigt. Der Querträger 3 weist an seiner unteren Gurtseite eine kegelförmige Vertiefung 32 auf, in die eine entsprechend geformte kegelförmige Erhebung 62 des Längsträgers 6 einpaßbar ist. Somit sind beim Aufstellen der Deckenschalung die Auflagerpositionen der Längsträger 6 und der der Querträger 3 einwandfrei und unzweifelhaft festgelegt. Diese mechanisch wirkenden, im wesentlichen formschlüssigen Vertiefungen 61 bzw. Erhebungen 62 sind in den gleichen Abständen anzubringen wie bei den Ausführungsbeispielen nach Fig. 1 bis 4.5 shows a cross section through a cross member 3 and an underlying longitudinal member 6 according to a further embodiment of the invention. The cross member 3 has on its lower belt side a conical recess 32 into which a correspondingly shaped conical projection 62 of the longitudinal member 6 can be fitted. Thus, when the slab formwork is erected, the support positions of the longitudinal beams 6 and that of the cross beams 3 are correctly and unequivocally defined. These mechanically acting, essentially positive recesses 61 or elevations 62 are to be provided at the same intervals as in the exemplary embodiments according to FIGS. 1 to 4.

In der Fig. 6 ist ein Querschnitt durch einen Längsträger 6 und einer darunterliegenden teilweise ausgebrochenen Stütze 1 gezeigt. Wie aus dieser Darstellung ersichtlich, sind wiederum die Längsträger 6 mit einer kegelförmigen Vertiefung 61 versehen, in die eine kegelförmige Erhebung 11 der Stütze 1 eingreift. Wiederum sind die kegelförmigen Vertiefungen 61 am Längsträger 6 an der Unterseite eines Gurtes des Längsträgers 6 eingeformt, wobei die gleichen Abstände wie bereits im vorigen Ausführungsbeispielen beschrieben einzuhalten sind.6 shows a cross section through a longitudinal beam 6 and a partially broken out support 1 below. As can be seen from this illustration, the longitudinal beams 6 are again provided with a conical depression 61, into which a conical elevation 11 of the support 1 engages. Again, the conical depressions 61 are formed on the side member 6 on the underside of a belt of the side member 6, the same distances as already described in the previous exemplary embodiments.

Ist das gesamte Deckenschalungssystem aufgestellt, so kann der Polier mit einem einfachen Kontrollblick die korrekten Abstände der einzelnen Elemente wie Stützen 1, 2, Längs- 6 und Querträger 3 zueinander kontrollieren, da die jeweils zugehörigen optischen Aufstellhilfen 31, 41, 63 bei korrekter Stellung entweder durch die Schalungselemente 1, 2, 3, 6 im wesentlichen verdeckt werden - sind diese auf der Unterseite der Elemente 1, 2, 3, 4, 6 angebracht - oder im wesentlichen im Bereich dieser Aufstellhilfen 31, 41, 63 die zugehörigen Decken-Schalungselemente 1, 2, 3, 4, 6 liegen müssen. Dies trifft ebenso für die mechanisch wirkenden Aufstellhilfen 11, 32, 61, 42 zu, die bei nicht korrekter Stellung offensichtlich nicht korrekt aufliegen bzw. eindeutig falsch angeordnet sind.Once the entire slab formwork system has been set up, the polisher can check the correct spacing of the individual elements such as supports 1, 2, longitudinal 6 and cross beams 3 from each other with a simple inspection, since the associated optical installation aids 31, 41, 63 either position correctly are essentially covered by the formwork elements 1, 2, 3, 6 - these are attached to the underside of the elements 1, 2, 3, 4, 6 - or essentially the associated ceiling formwork elements in the area of these installation aids 31, 41, 63 1, 2, 3, 4, 6 must be. This also applies to the mechanically acting set-up aids 11, 32, 61, 42, which obviously do not lie correctly on the incorrect position or are clearly arranged incorrectly.
