Definitions
- the invention relates to a slab formwork system with a plurality of grate elements, each consisting of a plurality of mutually parallel longitudinal members and at least one mounted on vertical supports or be laid, transverse to the longitudinal members extending cross member.
- Such a slab formwork system is known from German Offenlegungsschrift DE 102 34 445 A1 the applicant known.
- a plurality of mutually parallel side members are connected to each other via grills provided on its underside to each other to grate elements, that the relative positions of the side members are fixed to each other.
- the said spars are provided at a relatively large distance from the front ends of the side members spaced apart.
- each with the same grate elements can be placed with perpendicular to the cross beams longitudinal members on the cross member from above. Due to the fact that the longitudinal members are not fixedly connected to the cross members and the spars are provided spaced from the front ends of the longitudinal members, it is possible to interlock in the longitudinal direction adjacent grating elements with each other, so that in each case a portion of a longitudinal member of a grate element between two Side members of a comes to rest with this toothed grate element. In this way, a longitudinal compensation can be made by said intermeshing of the grate elements, which means that can be set with the said slab formwork system in the longitudinal direction of the side members individual dimensions that can be selected independently of the grid size of the grate elements.
- the length-adjustable plank consists essentially of two grate parts, which are each composed of two mutually parallel longitudinal members and perpendicular to these longitudinal members extending transverse webs.
- the longitudinal members of the second grate part have a slightly smaller distance than the longitudinal members of the first grate part, so that the second grate part can be moved together with its transverse webs in the longitudinal direction relative to the first grate part, provided that the second grate part by means of threaded spindles relative to the first Rust part was previously lowered.
- the second grate part can be raised again by means of the threaded spindles, whereby cross members of the second grate part come to lie alternately with cross members of the first grate part at the same height level. In this way can be realized with the length adjustable plank thus a longitudinal compensation.
- An object of the invention is to provide a slab formwork system of the type mentioned in such a way that a slab formwork can be adapted not only in the direction of the side members, but also perpendicular thereto to individual size ratios, in particular Also a quick, easy and safe mounting and dismounting of the slab formwork system should be ensured.
- This object is achieved by the features of claim 1 and in particular in that the longitudinal and transverse members of the grate elements are rigidly interconnected, wherein standard grate elements have two provided in the opposite end portions of the longitudinal beams cross member, while transverse compensation grate elements one or two in comparison to the standard grate elements in the longitudinal direction offset inwardly arranged have cross member.
- the longitudinal members of a grate element are not connected in a known manner via separate spars, but the connection of the longitudinal members of a grate element is realized directly via one or more fixedly connected to the longitudinal beams cross member, which in turn are then adapted to be placed or mounted on vertical supports to become.
- the invention thus already achieved that the number of parts to be handled compared to known slab formwork systems is reduced because cross members and side members each form firmly connected units or grate elements, so that cross member and side members no longer need to be handled separately.
- the grate elements are provided in at least two mutually different embodiments, with the standard grate elements defined above being realized in concrete terms, as well as the already mentioned cross-compensating grate elements.
- the standard grate elements defined above being realized in concrete terms, as well as the already mentioned cross-compensating grate elements.
- This Quunters Diess- and grate elements differ from the standard grate elements in that its or their cross member are further offset inwardly.
- This surprisingly simple measure makes it possible to interlock a standard grate element and a transverse compensating grate element in such a way that an outer longitudinal member or else a plurality of outer side members of a transverse compensation grate element respectively lie between two adjacent longitudinal members of the standard grate element.
- all the longitudinal members of the standard and the cross-compensation grate element extend parallel to each other, wherein they are all spaced from each other transversely to their longitudinal direction or arranged with their longitudinal sides adjacent to each other.
- the longitudinal members of the standard grate elements have the same length as those of the transverse compensation grate elements.
- Such a system which e.g. two different classes of standard grate elements and appropriately trained cross-compensating grate elements is used, will be explained in more detail in the description of the figures.
- the transverse compensation grate element according to the invention is "threaded" from below into the standard grate element, which means that first the one end ends of a respective desired number of longitudinal members of the transverse compensation grate element from below between the respective longitudinal members of the standard grate element introduced and moved over the one cross member of the standard rust element away from inside to outside. This movement is then continued in the direction of the longitudinal members until the other ends of the longitudinal members of the cross-compensation grate element can be raised above the other cross member of the standard grate element and supported on this.
- the said process of threading is described in more detail in the description of the figures.
- the distance between adjacent longitudinal members of the grate elements is at most 20 cm. With such distances can be avoided with the greatest possible certainty that a fitter can fall between two adjacent side members through, so that a mounted inventive grate element represents a reliable fall protection.
- the distance between adjacent side members must be at least as great as the width of the side members, so that a side member of a cross-compensating grate element between two adjacent side members of a standard grate element can be moved. It is particularly preferred if the distance between adjacent longitudinal members of the grate elements is at least two or three times the width of the longitudinal members.
- the already mentioned longitudinal compensation grate elements are provided in addition to the standard grate elements and the transverse compensation grate elements which have one or more cross members only in one of the two end regions of the side members facing away from one another ,
- longitudinal compensation grate elements and ceiling formwork systems can then be constructed, which have individual, continuously adjustable, bound to any pitch dimensions in the direction of the side members.
- the longitudinal compensation grate elements with their cross member or the cross member opposite side between two adjacent side members of a standard or a cross compensation grate element over the respective required distance insert are possible.
- the insertion must take place at least so far that the cross-beam-free ends of the longitudinal compensation grate element come to lie on cross members of a standard or a transverse compensation grate element. At most, the longitudinal compensation grate elements can be inserted so far until their cross members or their cross members abut the cross members of a standard grate element or a transverse compensation grate element. Infinitely any insertion positions can be selected between these two extreme positions in order to be able to produce individual dimensions in the direction of the longitudinal members.
- the longitudinal compensation grate elements can be inserted when the standard grate elements adjoining them and / or cross compensation grate elements already mounted. It is possible that when mounted slab formwork or the cross member of a longitudinal compensation grate element are arranged on the outside with respect to the overall formwork, wherein the longitudinal members of the longitudinal compensation grate element facing inward. Alternatively, however, it is also possible to slide a longitudinal compensation grate element from the bottom of another grate element forth with its cross beam free end from the inside via a cross member of the other grate element, so that the longitudinal members of the longitudinal compensation grate element ultimately in the mounted position on the cross member of the other grate element outwardly project.
- combi compensation grate elements are also provided which have one or more crossmembers offset inwardly in one of the two end regions of the side members facing away from one another. With such combination compensation grate elements can thus simultaneously a transverse compensation and a longitudinal compensation can be created. This will be illustrated in the description of the figures.
- a constellation can exist in certain installation situations in which a longitudinal support of a transverse compensation grate element, a longitudinal support of a longitudinal compensation grate element and also a longitudinal support of a combi balance element.
- Rust element come to rest between two adjacent longitudinal members of a standard grate element. In this case, then the distance between adjacent side members a standard grate element amount to at least three times the width of the side members. In principle, it is preferred if adjacent side members of all the grate elements are respectively spaced apart in the same way and / or if the side members of all grate elements have mutually equal lengths.
- Stirnabschalungs between the end regions of two adjacent side members can be attached to these.
- Stirnabschaloder can be mounted on these Stirnabschalungsriadn, which extend perpendicular to the actual formwork skin and thus limit a receiving area for the applied to the formwork concrete and frame.
- Such Stirnabschalungsriad can be particularly easy to assemble when the particular peripheral edge region of a mounted slab formwork is formed almost exclusively by longitudinal members, which extend perpendicular to the respective edge region. In this case, then Stirnabschalungs lacking can be mounted at any position between adjacent side rails.
- a side rail of at least one cross-compensation grate element is longer than the distance between two cross members of a standard grate element, wherein at the same time the remaining side members of the respective cross-compensation grate element are dimensioned shorter than the distance between two cross members of a standard grate element ,
- the transverse compensation grate element in a substantially vertically aligned position with to position the longer side member above a cross member of a standard grate element, then up in a further substantially vertical position and then to position with the other end of the longer side member above another cross member of the standard grate element, so that the cross compensation grate element vertically hanging coupled with the standard grate element. Subsequently, the transverse compensation grate element can then be pivoted into a substantially horizontal position.
- the longer side member of a transverse compensation grate element can protrude with its two end regions over the ends of the shorter longitudinal member of the respective transverse compensation grate element adjacent to it.
- the remaining, shorter side members of the cross-compensation grate element do not collide with cross members of a standard grate element when the cross-compensating grate element is pivoted into its horizontal position.
- the longitudinal extension of the longer longitudinal member of a transverse compensation grate element can substantially correspond to the distance of the mutually remote outer sides of two cross members of a standard grate element. In this way, it is achieved that the longer side member of the cross-compensating grate element in its mounted position does not project beyond the side members of that standard grate element into which it has been threaded.
- the longer side member preferably has a smaller cross-section and in particular a smaller height than the remaining side members of a cross-compensating grate element, this cross-section in particular being rectangular. It is particularly advantageous if the diagonal dimension of the longer longitudinal member is less than the height of the remaining side members. This ensures that the cross-compensating grate element can also be switched on and off when a formwork skin rests on the standard grate element, with which the cross-compensating grate element is or is coupled. Because of its dimensions, the longer side member does not abut on the underside of this formwork skin when the transverse compensation grate element is pivoted.
- the crossbeams of all grate elements present in the respective formwork are arranged below the longitudinal members. This ensures that the upper sides of the longitudinal members can each form smooth bearing surfaces for a formwork, which is not interrupted by any provided for top cross member grooves, recesses or the like. A direct contact between formwork and cross members so according to the invention does not take place, since only the tops of the side members form the support surface for the formwork.
- the side members of compensation grate elements can be placed on cross members of standard grate elements, so that these cross members support the compensation grate elements from below.
- Fig. 1 shows a standard grate element 2, which consists of a total of six parallel and spaced from each other extending longitudinal beams 4 and two cross members 5.
- the two cross members 5 extend perpendicular to the longitudinal members 4, wherein in each case one cross member 5 in each the two opposite end portions of the side members 4 is fixed.
- Fig. 2 shows a cross-compensating grate element 6, which also consists of six parallel and spaced apart extending longitudinal beams 8 and two perpendicular thereto extending cross members 10.
- the side members 10 of the cross-compensation grate element are compared to the standard grate element 2 according to Fig. 1 arranged offset inwards, so that they ultimately do not come to rest in the end-side end portions of the side rail 8.
- Said offset of the cross member 10 is significantly greater than the width of the cross member 5 of the standard grate element 2, preferably, the offset is approximately three times the said width (for example, about 13 cm).
- Fig. 3 shows a longitudinal compensation grate element 12, which in turn consists of six parallel and spaced apart extending longitudinal beams 14 and two perpendicular thereto extending cross members 16.
- the cross members 16 are both arranged in the same end-side end region of the longitudinal members 14, which leads to the fact that the opposite end-side end region of the side members 14 is designed without crossbeams.
- cross member 16 can also use only such a cross member 16 are used, the embodiment with two cross members 16, however, 12 is advantageous in terms of stability of the longitudinal compensation grate element.
- the top of the side members 4, 8, 14 forms in the mounted state of the grate elements 2, 6, 12 a support surface for a final applied formwork, which may for example consist of wood flooring, which in a suitable manner with the top of the side members 4, 8, 14 connected become.
- each open profiles or hollow sections can be used, with the same profile shape can be used for all longitudinal beams 4, 8, 14. Likewise, a certain profile shape can also be used for all cross members 5, 10, 16. However, the profile shape of the side members 4, 8, 14 may differ from the profile shape of the cross members 5, 10, 16.
- the cross members 5, 10, 16 are completely below the respective side members 4, 8, 14 in the assembled state of a slab formwork, which means that the side members 4, 8, 14 extend in another plane as the cross members 5, 10, 16, wherein the two said levels but adjacent to each other.
- Longitudinal and transverse beams 4, 8, 14; 6, 10, 16 may for example be welded together, bolted or riveted.
- a cross-compensating grate element 6 is to be coupled to an already mounted standard grate element 2, according to Fig. 4a a respective desired number of longitudinal members 8 of the transverse compensation grate element 6 is threaded between each adjacent longitudinal member 4 of a standard grate element 2 until the ends of the threaded side members 8 of the transverse compensation grate element 6 above a cross member 5 of the standard grate element 2 are located. This position is in Fig. 4a shown.
- the transverse compensation grate element 6 can then be pivoted upward in the direction of the arrow about an axis extending in the region of the cross member 5, until the side members 8 of the transverse compensation grate element 6 are in the same plane as the longitudinal members 4 of the standard grate element 2.
- This position is in Fig. 4b shown.
- the longitudinal members 4, 8 of the two grate elements 2, 6 are not flush with each other in this assembly stage, but rather collar the ends of the side members 8 of the cross-compensation grate element 6 beyond the ends of the side members 4 of the standard grate element 2 addition.
- Fig. 4b shown position is then the cross compensation grate element 6 in the arrow direction Fig. 4b linearly displaced until the end faces of the side members 4, 8 of both grate elements 2, 6 are aligned with each other, and this in Fig. 4c is shown. Due to the inwardly offset arrangement of the cross member 10 on the cross compensation grate element 6 is in conjunction with Fig. 4 described threading a cross compensation grate element 6 in a standard grate element 2 possible without the cross member 5, 10 of both grate elements 2, 6 collide with each other.

Description
Die Erfindung betrifft ein Deckenschalungssystem mit mehreren Rostelementen, welche jeweils aus einer Mehrzahl von parallel zueinander verlaufenden Längsträgern und zumindest einem auf Vertikalstützen montier- oder auflegbaren, quer zu den Längsträgern verlaufenden Querträger bestehen.The invention relates to a slab formwork system with a plurality of grate elements, each consisting of a plurality of mutually parallel longitudinal members and at least one mounted on vertical supports or be laid, transverse to the longitudinal members extending cross member.

Bei der Montage des bekannten Deckenschalungssystems werden zuerst Querträger auf Vertikalstützen montiert, woraufhin dann die aus den Längsträgern und Holmen bestehenden, untereinander jeweils gleichen Rostelemente mit senkrecht zu den Querträgern verlaufenden Längsträgern auf die Querträger von oben aufgelegt werden können. Aufgrund der Tatsache, dass die Längsträger mit den Querträgern nicht fest verbunden und die Holme beabstandet zu den stirnseitigen Enden der Längsträger vorgesehen sind, ist es möglich, in Längsrichtung aneinander angrenzende Rostelemente miteinander zu verzahnen, so dass jeweils ein Abschnitt eines Längsträgers eines Rostelements zwischen zwei Längsträgern eines mit diesem verzahnten Rostelements zu liegen kommt. Auf diese Weise kann durch das genannte Verzahnen der Rostelemente ein Längsausgleich vorgenommen werden, was bedeutet, dass sich mit dem genannten Deckenschalungssystem in Längsrichtung der Längsträger individuelle Abmessungen einstellen lassen, die unabhängig vom Rastermaß der Rostelemente gewählt werden können.When mounting the known slab formwork first cross member are mounted on vertical supports, whereupon the existing from the side rails and spars, each with the same grate elements can be placed with perpendicular to the cross beams longitudinal members on the cross member from above. Due to the fact that the longitudinal members are not fixedly connected to the cross members and the spars are provided spaced from the front ends of the longitudinal members, it is possible to interlock in the longitudinal direction adjacent grating elements with each other, so that in each case a portion of a longitudinal member of a grate element between two Side members of a comes to rest with this toothed grate element. In this way, a longitudinal compensation can be made by said intermeshing of the grate elements, which means that can be set with the said slab formwork system in the longitudinal direction of the side members individual dimensions that can be selected independently of the grid size of the grate elements.

Eine Aufgabe der Erfindung besteht darin, ein Deckenschalungssystem der eingangs genannten Art derart weiterzubilden, dass sich eine Deckenschalung nicht nur in Richtung der Längsträger, sondern auch senkrecht hierzu an individuelle Größenverhältnisse anpassen lässt, wobei insbesondere auch ein möglichst schnelles, einfaches und sicheres Montieren und Demontieren des Deckenschalungssystems sichergestellt werden soll. Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 und insbesondere dadurch gelöst, dass Längs- und Querträger der Rostelemente starr miteinander verbunden sind, wobei Standard-Rostelemente zwei in den einander abgewandten Endbereichen der Längsträger vorgesehene Querträger aufweisen, während Querausgleichs-Rostelemente einen oder zwei im Vergleich zu den Standard-Rostelementen in die Längsrichtung nach innen versetzt angeordnete Querträger besitzen.An object of the invention is to provide a slab formwork system of the type mentioned in such a way that a slab formwork can be adapted not only in the direction of the side members, but also perpendicular thereto to individual size ratios, in particular Also a quick, easy and safe mounting and dismounting of the slab formwork system should be ensured. This object is achieved by the features of claim 1 and in particular in that the longitudinal and transverse members of the grate elements are rigidly interconnected, wherein standard grate elements have two provided in the opposite end portions of the longitudinal beams cross member, while transverse compensation grate elements one or two in comparison to the standard grate elements in the longitudinal direction offset inwardly arranged have cross member.
Erfindungsgemäß werden also die Längsträger eines Rostelements nicht in bekannter Weise über separate Holme miteinander verbunden, sondern die Verbindung der Längsträger eines Rostelements wird direkt über einen oder mehrere fest mit den Längsträgern verbundene Querträger realisiert, welche dann ihrerseits dazu geeignet sind, auf Vertikalstützen aufgelegt oder montiert zu werden. Insofern wird erfindungsgemäß also bereits erreicht, dass die Anzahl der zu handhabenden Teile gegenüber bekannten Deckenschalungssystemen reduziert wird, da Querträger und Längsträger jeweils fest miteinander verbundene Einheiten bzw. Rostelemente bilden, so dass Querträger und Längsträger nicht mehr separat voneinander gehandhabt werden müssen.According to the invention, therefore, the longitudinal members of a grate element are not connected in a known manner via separate spars, but the connection of the longitudinal members of a grate element is realized directly via one or more fixedly connected to the longitudinal beams cross member, which in turn are then adapted to be placed or mounted on vertical supports to become. In this respect, the invention thus already achieved that the number of parts to be handled compared to known slab formwork systems is reduced because cross members and side members each form firmly connected units or grate elements, so that cross member and side members no longer need to be handled separately.
Ferner werden die Rostelemente im Rahmen eines erfindungsgemäßen Systems in zumindest zwei voneinander verschiedenen Ausführungsformen bereitgestellt, wobei hier konkret die vorstehend definierten Standard-Rostelemente ebenso wie die bereits genannten Querausgleichs-Rostelemente realisiert werden. Bei der Montage eines Deckenschalungssystems, dessen Größe in jeder Richtung einem ganzzahligen Vielfachen des jeweiligen Rastermaßes der Standard-Rostelemente entspricht, ist es möglich, ausschließlich Standard-Rostelemente zu verwenden, welche in keiner Weise miteinander verzahnt sind. Wenn es jedoch z.B. nötig ist, in einer senkrecht zu den Längsträgern verlaufenden Richtung individuelle Abmessungen außerhalb des Rastermaßes zu schaffen, kommen zusätzlich zu den Standard-Rostelementen erfindungsgemäß auch Querausgleichs-Rostelemente zum Einsatz. Diese Querausgleichs- und Rostelemente unterscheiden sich von den Standard-Rostelementen dadurch, dass dessen bzw. deren Querträger weiter nach innen versetzt angeordnet sind. Durch diese überraschend einfache Maßnahme wird es möglich, ein Standard-Rostelement und ein Querausgleichs-Rostelement derart miteinander zu verzahnen, dass ein äußerer Längsträger oder auch mehrere äußere Längsträger eines Querausgleichs-Rostelements jeweils zwischen zwei benachbarten Längsträgern des Standard-Rostelements zu liegen kommen. In diesem Fall erstrecken sich dann alle Längsträger des Standard- und des Querausgleichs-Rostelements parallel zueinander, wobei sie alle quer zu ihrer Längsrichtung voneinander beabstandet oder mit ihren Längsseiten aneinander angrenzend angeordnet sind. Somit lassen sich in einer senkrecht zu den Längsträgern verlaufenden Querrichtung individuelle, kontinuierlich einstellbare, an keinerlei Rastermaß gebundene Abmessungen dadurch realisieren, dass die jeweils gewünschte Anzahl von Längsträgern eines Querausgleichs-Rostelements zwischen jeweils zwei benachbarten Längsträgern eines Standard-Rostelements positioniert wird. Durch die voneinander verschiedene Anbringung der Querträger an den Standard-Rostelementen und den Querausgleichs-Rostelementen wird dabei sichergestellt, dass die Querträger miteinander verzahnter Standard- und Querausgleichs-Rostelemente nicht miteinander kollidieren. Vielmehr verlaufen die Querträger aller miteinander verzahnten Rostelemente entweder senkrecht beabstandet zueinander oder die Querträger miteinander verzahnter Rostelemente liegen aneinander an.Furthermore, in the context of a system according to the invention, the grate elements are provided in at least two mutually different embodiments, with the standard grate elements defined above being realized in concrete terms, as well as the already mentioned cross-compensating grate elements. When mounting a slab formwork system whose size in each direction corresponds to an integer multiple of the respective grid dimension of the standard grate elements, it is possible to use only standard grate elements, which are not interlocked in any way. However, if it is necessary, for example, to provide individual dimensions outside the grid dimension in a direction perpendicular to the longitudinal members, transverse compensating grid elements are also used according to the invention in addition to the standard grid elements. This Querausgleichs- and grate elements differ from the standard grate elements in that its or their cross member are further offset inwardly. This surprisingly simple measure makes it possible to interlock a standard grate element and a transverse compensating grate element in such a way that an outer longitudinal member or else a plurality of outer side members of a transverse compensation grate element respectively lie between two adjacent longitudinal members of the standard grate element. In this case, then all the longitudinal members of the standard and the cross-compensation grate element extend parallel to each other, wherein they are all spaced from each other transversely to their longitudinal direction or arranged with their longitudinal sides adjacent to each other. Thus, in a direction perpendicular to the longitudinal beams transverse direction individual, continuously adjustable, not bound to any grid dimensions realize that the respectively desired number of longitudinal members of a cross-compensating grate element between each two adjacent longitudinal members of a standard grate element is positioned. By the different attachment of the cross member to the standard grate elements and the cross compensation grate elements is thereby ensured that the cross member interlocked standard and cross compensation grate elements do not collide with each other. Rather, the cross member of all intermeshed grate elements extend either perpendicular to each other or the cross member interlocked grate elements abut each other.
Bevorzugt ist es, wenn die Längsträger der Standard-Rostelemente die gleiche Länge besitzen wie diejenigen der Querausgleichs-Rostelemente. Im Rahmen eines Deckenschalungssystems können dabei jedoch durchaus beispielsweise zwei oder mehr Klassen bzw. Typen von Rostelementen mit jeweils voneinander verschiedenen Abmessungen eingesetzt werden, wobei dann zu jeder Klasse Standard-Rostelemente und zumindest entsprechende Querausgleichs-Rostelemente existieren, deren Längsträger die gleichen Abmessungen besitzen, wie diejenigen der Standard-Rostelemente der jeweiligen Klasse. Ein derartiges System, welches z.B. zwei unterschiedliche Klassen von Standard-Rostelementen und entsprechend ausgebildete Querausgleichs-Rostelemente einsetzt, wird im Rahmen der Figurenbeschreibung noch näher erläutert.It is preferred if the longitudinal members of the standard grate elements have the same length as those of the transverse compensation grate elements. In the context of a slab formwork system, however, it is certainly possible for example to use two or more classes or types of grate elements each having different dimensions, in which case standard grate elements and at least corresponding transverse compensation grate elements exist for each class, the longitudinal members of which have the same dimensions those of the standard grate elements of the respective class. Such a system, which e.g. two different classes of standard grate elements and appropriately trained cross-compensating grate elements is used, will be explained in more detail in the description of the figures.
Wenn die Längsträger der Standard-Rostelemente eines Typs die gleiche Länge besitzen wie diejenigen der Querausgleichs-Rostelemente desselben Typs, ist es nicht möglich, Querausgleichs-Rostelemente linear von unten an ein bereits montiertes Standard-Rostelement heranzuführen und mit diesem im Rahmen einer reinen Linearbewegung zu verzahnen, da in diesem Fall die einander abgewandten Enden der Längsträger des Querausgleichs-Rostelements mit den Querträgern des Standard-Rostelements kollidieren würden. In diesem Fall wird vielmehr das erfindungsgemäße Querausgleichs-Rostelement in das Standard-Rostelement von unten "eingefädelt", was bedeutet, dass zuerst die einen stirnseitigen Enden einer jeweils gewünschten Anzahl von Längsträgern des Querausgleichs-Rostelements von unten zwischen die jeweiligen Längsträger des Standard-Rostelements eingeführt und über den einen Querträger des Standard-Rostelements hinweg von innen nach außen bewegt werden. Diese Bewegung wird dann in Richtung der Längsträger fortgesetzt, bis die anderen Enden der Längsträger des Querausgleichs-Rostelements über den anderen Querträger des Standard-Rostelements angehoben und auf diesem abgestützt werden können. Der genannte Prozess des Einfädelns wird im Rahmen der Figurenbeschreibung noch eingehender beschrieben.If the side rails of the standard grate elements of one type have the same length as those of the cross balancing grate elements of the same type, it is not possible to linearly transversely offset grate elements from below to an already mounted standard grate element and with this in the context of a pure linear movement intermesh, since in this case the opposite ends of the side members of the cross-compensation grate element would collide with the cross members of the standard grate element. In this case, rather, the transverse compensation grate element according to the invention is "threaded" from below into the standard grate element, which means that first the one end ends of a respective desired number of longitudinal members of the transverse compensation grate element from below between the respective longitudinal members of the standard grate element introduced and moved over the one cross member of the standard rust element away from inside to outside. This movement is then continued in the direction of the longitudinal members until the other ends of the longitudinal members of the cross-compensation grate element can be raised above the other cross member of the standard grate element and supported on this. The said process of threading is described in more detail in the description of the figures.
Von Vorteil ist es weiterhin, wenn der Abstand benachbarter Längsträger der Rostelemente höchstens 20 cm beträgt. Bei derartigen Abständen kann mit größtmöglicher Sicherheit vermieden werden, dass ein Monteur zwischen zwei benachbarten Längsträgern hindurch fallen kann, so dass ein montiertes erfindungsgemäßes Rostelement eine zuverlässige Absturzsicherung darstellt. Der Abstand benachbarter Längsträger muss dabei jedoch zumindest so groß sein wie die Breite der Längsträger, damit ein Längsträger eines Querausgleichs-Rostelements zwischen zwei benachbarte Längsträger eines Standard-Rostelements bewegt werden kann. Besonders bevorzugt ist es, wenn der Abstand benachbarter Längsträger der Rostelemente zumindest das Zwei- oder Dreifache der Breite der Längsträger beträgt. In diesem Fall kann dann zusätzlich mit Längsausgleichs-Rostelementen und/oder Kombiausgleichs-Rostelementen gearbeitet werden, auf welche nachfolgend noch näher eingegangen wird. Grundsätzlich ist es auch möglich, den Abstand benachbarter Längsträger auf zumindest das Fünffache der Breite der Längsträger zu erhöhen. Auf diese Weise werden zusätzliche Kombinationsmöglichkeiten aller zur Verfügung stehender Rostelemente ermöglicht.It is also advantageous if the distance between adjacent longitudinal members of the grate elements is at most 20 cm. With such distances can be avoided with the greatest possible certainty that a fitter can fall between two adjacent side members through, so that a mounted inventive grate element represents a reliable fall protection. However, the distance between adjacent side members must be at least as great as the width of the side members, so that a side member of a cross-compensating grate element between two adjacent side members of a standard grate element can be moved. It is particularly preferred if the distance between adjacent longitudinal members of the grate elements is at least two or three times the width of the longitudinal members. In this case, it is then additionally possible to work with longitudinal compensation grate elements and / or combination compensation grate elements, which will be discussed in more detail below. In principle, it is also possible to increase the distance between adjacent side members to at least five times the width of the side members. In this way Additional combinations of all available grate elements are possible.
Besonders bevorzugt ist es, wenn im Rahmen eines erfindungsgemäßen Deckenschalungssystems neben den Standard-Rostelementen und den Querausgleichs-Rostelementen auch noch die bereits erwähnten Längsausgleichs-Rostelemente zur Verfügung gestellt werden, welche nur in einem der beiden einander abgewandten Endbereiche der Längsträger einen oder mehrere Querträger aufweisen. Mit derartigen Längsausgleichs-Rostelementen können dann auch Deckenschalungssysteme aufgebaut werden, welche in Richtung der Längsträger individuelle, kontinuierlich einstellbare, an keinerlei Rastermaß gebundene Abmessungen auf-weisen. Konkret wird es durch die Anordnung des bzw. der Querträger in nur einem Endbereich der Längsträger möglich, die Längsausgleichs-Rostelemente mit ihrer dem bzw. den Querträgern gegenüberliegenden querträgerfreien Seite zwischen zwei benachbarte Längsträger eines Standard- oder eines Querausgleichs-Rostelements über die jeweils erforderliche Strecke einzuschieben. Das Einschieben muss dabei mindestens so weit erfolgen, dass die querträgerfreien Enden des Längsausgleichs-Rostelements auf Querträgern eines Standard- oder eines Querausgleichs-Rostelements zu liegen kommen. Maximal können die Längsausgleichs-Rostelemente so weit eingeschoben werden, bis ihr Querträger bzw. ihre Querträger an den Querträgern eines Standard-Rostelements oder eines Querausgleichs-Rostelements anstoßen. Zwischen diesen beiden Extremstellungen sind stufenlos beliebige Einschubpositionen wählbar, um hier jeweils individuelle Abmessungen in Richtung der Längsträger herstellen zu können.It is particularly preferred if, in the context of a slab formwork system according to the invention, the already mentioned longitudinal compensation grate elements are provided in addition to the standard grate elements and the transverse compensation grate elements which have one or more cross members only in one of the two end regions of the side members facing away from one another , With such longitudinal compensation grate elements and ceiling formwork systems can then be constructed, which have individual, continuously adjustable, bound to any pitch dimensions in the direction of the side members. Specifically, it is possible by the arrangement of the or the cross member in only one end of the side members, the longitudinal compensation grate elements with their cross member or the cross member opposite side between two adjacent side members of a standard or a cross compensation grate element over the respective required distance insert. The insertion must take place at least so far that the cross-beam-free ends of the longitudinal compensation grate element come to lie on cross members of a standard or a transverse compensation grate element. At most, the longitudinal compensation grate elements can be inserted so far until their cross members or their cross members abut the cross members of a standard grate element or a transverse compensation grate element. Infinitely any insertion positions can be selected between these two extreme positions in order to be able to produce individual dimensions in the direction of the longitudinal members.
Die Längsausgleichs-Rostelemente können eingeschoben werden, wenn die an sie angrenzenden Standard-Rostelemente und/oder Querausgleichs-Rostelemente bereits montiert sind. Dabei ist es möglich, dass bei montierter Deckenschalung der oder die Querträger eines Längsausgleichs-Rostelements bezogen auf die Gesamtschalung außen angeordnet sind, wobei die Längsträger des Längsausgleichs-Rostelements nach innen weisen. Alternativ ist es jedoch auch möglich, ein Längsausgleichs-Rostelement von der Unterseite eines anderen Rostelements her mit seinem querträgerfreien Ende voran von innen über einen Querträger des anderen Rostelements zu schieben, so dass die Längsträger des Längsausgleichs-Rostelements letztlich in der montierten Position über die Querträger des anderen Rostelements nach außen hinauskragen.The longitudinal compensation grate elements can be inserted when the standard grate elements adjoining them and / or cross compensation grate elements already mounted. It is possible that when mounted slab formwork or the cross member of a longitudinal compensation grate element are arranged on the outside with respect to the overall formwork, wherein the longitudinal members of the longitudinal compensation grate element facing inward. Alternatively, however, it is also possible to slide a longitudinal compensation grate element from the bottom of another grate element forth with its cross beam free end from the inside via a cross member of the other grate element, so that the longitudinal members of the longitudinal compensation grate element ultimately in the mounted position on the cross member of the other grate element outwardly project.
Ferner ist es bevorzugt, wenn im Rahmen des erfindungsgemäßen Deckenschalungssystems auch noch Kombiausgleichs-Rostelemente zur Verfügung gestellt werden, welche nur in einem der beiden einander abgewandten Endbereiche der Längsträger einen oder mehrere im Vergleich zu den Längsausgleichs-Rostelementen nach innen versetzt angeordnete Querträger aufweisen. Mit derartigen Kombiausgleichs-Rostelementen kann somit gleichzeitig ein Querausgleich als auch ein Längsausgleich geschaffen werden. Dies wird im Rahmen der Figurenbeschreibung noch veranschaulicht.Furthermore, it is preferable if, in the context of the slab formwork system according to the invention, combi compensation grate elements are also provided which have one or more crossmembers offset inwardly in one of the two end regions of the side members facing away from one another. With such combination compensation grate elements can thus simultaneously a transverse compensation and a longitudinal compensation can be created. This will be illustrated in the description of the figures.
Wenn erfindungsgemäß neben Standard-Rostelementen Querausgleichs-Rostelemente, Längsausgleichs-Rostelemente und Kombiausgleichs-Rostelemente eingesetzt werden, kann bei bestimmten Einbausituationen eine Konstellation existieren, bei der ein Längsträger eines Querausgleichs-Rostelements, ein Längsträger eines Längsausgleichs-Rostelements und auch ein Längsträger eines Kombiausgleichs-Rostelements zwischen zwei benachbarten Längsträgern eines Standard-Rostelements zu liegen kommen. In diesem Fall muss dann der Abstand benachbarter Längsträger eines Standard-Rostelements zumindest das Dreifache der Breite der Längsträger betragen.
Grundsätzlich ist es bevorzugt, wenn benachbarte Längsträger aller Rostelemente jeweils in gleicher Weise voneinander beabstandet sind und/oder wenn die Längsträger aller Rostelemente untereinander gleiche Längen aufweisen.If, in addition to standard grate elements, transverse compensation grate elements, longitudinal compensation grate elements and combination compensation grate elements are used according to the invention, a constellation can exist in certain installation situations in which a longitudinal support of a transverse compensation grate element, a longitudinal support of a longitudinal compensation grate element and also a longitudinal support of a combi balance element. Rust element come to rest between two adjacent longitudinal members of a standard grate element. In this case, then the distance between adjacent side members a standard grate element amount to at least three times the width of the side members.
In principle, it is preferred if adjacent side members of all the grate elements are respectively spaced apart in the same way and / or if the side members of all grate elements have mutually equal lengths.
Vorteilhaft ist es weiterhin, wenn Stirnabschalungsträger zwischen den Endbereichen zweier benachbarter Längsträger an diesen befestigbar sind. Auf diese Weise können dann Stirnabschalungen an diesen Stirnabschalungsträgern montiert werden, welche sich senkrecht zur eigentlichen Schalhaut erstrecken und somit einen Aufnahmebereich für den auf die Schalhaut aufzubringenden Beton begrenzen und umrahmen. Besonders einfach lassen sich derartige Stirnabschalungsträger montieren, wenn der insbesondere umlaufende Randbereich einer montierten Deckenschalung praktisch ausschließlich durch Längsträger gebildet ist, welche senkrecht zum jeweiligen Randbereich verlaufen. In diesem Fall können dann an beliebigen Stellen zwischen benachbarten Längsträgern Stirnabschalungsträger montiert werden.It is also advantageous if Stirnabschalungsträger between the end regions of two adjacent side members can be attached to these. In this way, then Stirnabschalungen can be mounted on these Stirnabschalungsträgern, which extend perpendicular to the actual formwork skin and thus limit a receiving area for the applied to the formwork concrete and frame. Such Stirnabschalungsträger can be particularly easy to assemble when the particular peripheral edge region of a mounted slab formwork is formed almost exclusively by longitudinal members, which extend perpendicular to the respective edge region. In this case, then Stirnabschalungsträger can be mounted at any position between adjacent side rails.
Besonders bevorzugt ist es, wenn ein Längsträger zumindest eines Querausgleichs-Rostelements länger ausgebildet ist als der Abstand zwischen zwei Querträgern eines Standard-Rostelements, wobei gleichzeitig die restlichen Längsträger des jeweiligen Querausgleichs-Rostelements kürzer bemessen sind als der Abstand zwischen zwei Querträgern eines Standard-Rostelements. Durch diese Ausbildung eines Querausgleichs-Rostelements wird erreicht, dass bei der Montage das Querausgleichs-Rostelement nicht vollständig über Kopf in ein Standard-Rostelement eingefädelt werden muss. Vielmehr ist es möglich, das Querausgleichs-Rostelement in einer im Wesentlichen vertikal ausgerichteten Position mit dem längeren Längsträger oberhalb eines Querträgers eines Standard-Rostelements zu positionieren, anschließend in einer weiterhin im Wesentlichen vertikalen Position hochzuschwenken und dann auch mit dem anderen Ende des längeren Längsträgers oberhalb eines weiteren Querträgeres des Standard-Rostelements zu positionieren, so dass das Querausgleichs-Rostelement vertikal hängend mit dem Standard-Rostelement gekoppelt ist. Anschließend kann dann das Querausgleichs-Rostelement in eine im Wesentlichen horizontale Position verschwenkt werden. Bei dem letztgenannten Schwenkvorgang, bei dessen Abschluss der Monteur letztlich wiederum über Kopf arbeiten muss, wird dann ein Großteil des Gewichts des Querausgleichs-Rostelements bereits von den Querträgern des Standard-Rostelements aufgenommen, so dass sich für den Monteur eine wesentlich erleichterte Handhabung ergibt. Das genannte Prinzip wird nachstehend anhand der
Bei der letztgenannten bevorzugten Ausführungsform der Erfindung ist es weiterhin vorteilhaft, wenn nur einer der ganz außen liegenden Längsträger eines Querausgleichs-Rostelements länger ausgebildet ist als die restlichen Längsträger des jeweiligen Querausgleichs-Rostelements. Durch diese Maßnahme wird erreicht, dass das Querausgleichs-Rostelement beim Einfädeln des längeren Längsträgers in ein Standard-Rostelement nur über eine möglichst geringe Höhe angehoben werden muss.In the last-mentioned preferred embodiment of the invention, it is furthermore advantageous if only one of the very outer longitudinal members of a transverse compensation grate element is designed to be longer than the remaining longitudinal members of the respective transverse compensation grate element. By this measure it is achieved that the cross-compensating grate element when threading the longer side member in a standard grate element must be raised only over the smallest possible height.
Der längere Längsträger eines Querausgleichs-Rostelements kann mit seinen beiden Endbereichen über die Enden des ihm benachbarten kürzeren Längsträgers des jeweiligen Querausgleichs-Rostelements überstehen. So kann sichergestellt werden, dass die restlichen, kürzeren Längsträger des Querausgleichs-Rostelements nicht mit Querträgern eines Standard-Rostelements kollidieren, wenn das Querausgleichs-Rostelement in seine horizontale Position verschwenkt wird.The longer side member of a transverse compensation grate element can protrude with its two end regions over the ends of the shorter longitudinal member of the respective transverse compensation grate element adjacent to it. Thus it can be ensured that the remaining, shorter side members of the cross-compensation grate element do not collide with cross members of a standard grate element when the cross-compensating grate element is pivoted into its horizontal position.
Die Längserstreckung des längeren Längsträgers eines Querausgleichs-Rostelements kann im Wesentlichen dem Abstand der einander abgewandten Außenseiten zweier Querträger eines Standard-Rostelements entsprechen. Auf diese Weise wird erreicht, dass der längere Längsträger des Querausgleichs-Rostelements in seiner montierten Stellung nicht über die Längsträger desjenigen Standard-Rostelements übersteht, in das er eingefädelt wurde.The longitudinal extension of the longer longitudinal member of a transverse compensation grate element can substantially correspond to the distance of the mutually remote outer sides of two cross members of a standard grate element. In this way, it is achieved that the longer side member of the cross-compensating grate element in its mounted position does not project beyond the side members of that standard grate element into which it has been threaded.
Der längere Längsträger besitzt bevorzugt einen kleineren Querschnitt und insbesondere eine geringere Höhe als die restlichen Längsträger eines Querausgleichs-Rostelements, wobei dieser Querschnitt insbesondere rechteckig ist. Besonders vorteilhaft ist es, wenn das Diagonalmaß des längeren Längsträgers geringer ist als die Höhe der restlichen Längsträger. Hierdurch wird erreicht, dass das Querausgleichs-Rostelement auch dann ein- und ausgeschalt werden kann, wenn auf dem Standard-Rostelement, mit welchem das Querausgleichs-Rostelement gekoppelt wird bzw. ist, eine Schalhaut aufliegt. Der längere Längsträger stößt dann nämlich aufgrund seiner genannten Abmessungen bei einem Verschwenken des Querausgleichs-Rostelement nicht an der Unterseite dieser Schalhaut an.The longer side member preferably has a smaller cross-section and in particular a smaller height than the remaining side members of a cross-compensating grate element, this cross-section in particular being rectangular. It is particularly advantageous if the diagonal dimension of the longer longitudinal member is less than the height of the remaining side members. This ensures that the cross-compensating grate element can also be switched on and off when a formwork skin rests on the standard grate element, with which the cross-compensating grate element is or is coupled. Because of its dimensions, the longer side member does not abut on the underside of this formwork skin when the transverse compensation grate element is pivoted.
Bei montierter Deckenschalung sind bevorzugt die Querträger aller in der jeweiligen Schalung jeweils vorhandenen Rostelemente unterhalb der Längsträger angeordnet. Hierdurch wird erreicht, dass die Oberseiten der Längsträger jeweils glatte Auflageflächen für eine Schalhaut bilden können, die durch keinerlei für oben verlaufende Querträger vorgesehene Nuten, Ausnehmungen oder dergleichen unterbrochen ist. Ein direkter Kontakt zwischen Schalhaut und Querträgern findet erfindungsgemäß also nicht statt, da ausschließlich die Oberseiten der Längsträger die Auflagefläche für die Schalhaut bilden.When the slab formwork is installed, preferably the crossbeams of all grate elements present in the respective formwork are arranged below the longitudinal members. This ensures that the upper sides of the longitudinal members can each form smooth bearing surfaces for a formwork, which is not interrupted by any provided for top cross member grooves, recesses or the like. A direct contact between formwork and cross members so according to the invention does not take place, since only the tops of the side members form the support surface for the formwork.
Zudem wird es durch die Anordnung der Querträger unterhalb der Längsträger möglich, die Längsträger von Ausgleichs-Rostelementen auf Querträger von Standard-Rostelementen aufgelegt werden können, so dass diese Querträger die Ausgleichs-Rostelemente von unten unterstützen.In addition, it is possible by the arrangement of the cross member below the side members, the side members of compensation grate elements can be placed on cross members of standard grate elements, so that these cross members support the compensation grate elements from below.
Weitere bevorzugte Ausführungsformen der Erfindung sind in den Unteransprüchen beschrieben.Further preferred embodiments of the invention are described in the subclaims.

Ebenso kann eine bestimmte Profilform auch für alle Querträger 5, 10, 16 eingesetzt werden. Die Profilform der Längsträger, 4, 8, 14 kann sich dabei jedoch von der Profilform der Querträger 5, 10, 16 unterscheiden.Both for the
Bei allen Rostelementen 2, 6, 12 befinden sich die Querträger 5, 10, 16 im montierten Zustand einer Deckenschalung vollständig unterhalb der jeweiligen Längsträger 4, 8, 14, was bedeutet, dass sich die Längsträger 4, 8, 14 in einer anderen Ebene erstrecken als die Querträger 5, 10, 16, wobei die beiden genannten Ebenen jedoch aneinander angrenzen.In the case of all the
Längs- und Querträger 4, 8, 14; 6, 10, 16 können beispielsweise miteinander verschweißt, verschraubt oder vernietet sein.Longitudinal and

Die Deckenschalung gemäß
Zur einfacheren Erläuterung des Aufbaus des Deckenschalungssystems gemäß
Die Basis des Deckenschalungssystems gemäß
Im Bereich des Randabschnitts C sind zwei in Richtung der Längsträger aneinander anschließende Querausgleichs-Rostelemente 6 vorgesehen, welche mit jeweils einem Standard-Rostelement 2 verzahnt sind, indem die Querausgleichs-Rostelemente 6 gemäß
Die Randabschnitte D und F werden von einem Längsausgleichs-Rostelement 12 gebildet, welches so weit in ein Querausgleichs-Rostelement 6 eingeschoben ist, dass sich die freien Enden der Längsträger des Längsausgleichs-Rostelements 12 auf einem Querträger des Querausgleichs-Rostelements 6 abstützen. Drei Längsträger des Längsausgleichs-Rostelements 12 kommen zwischen jeweils zwei benachbarten Längsträgern des Querausgleichs-Rostelements 6 zu liegen, wohingegen die drei anderen Längsträger des Längsausgleichs-Rostelements 12 jeweils zwischen einem Längsträger des Querausgleichs-Rostelements 6 und einem Längsträger desjenigen Standard-Rostelements 2 zu liegen kommen, welches mit demjenigen Querausgleichs-Rostelement 6 verzahnt ist, auf dessen Querträger sich die Längsträger des Längsausgleichs-Rostelements 12 abstützen.The edge sections D and F are formed by a longitudinal
Der Randabschnitt G wird von einem weiteren Längsausgleichs-Rostelement 12 gebildet, welches mit zwei Längsträgern so weit in das bezüglich des Randabschnitts D genannte Längsausgleichs-Rostelement 12 eingeschoben ist, dass die Querträger der beiden Längsausgleichs-Rostelemente 12 aneinander abschnittsweise zur Anlage kommen. Die freien Enden des den Randabschnitt G bildenden Längsausgleichs-Rostelements 12 sind auf einem Querträger desjenigen Standard-Rostelements 2 abgestützt, welcher mit dem einen Teil des Randabschnitts C bildenden Querausgleichs-Rostelements 6 verzahnt ist.The edge portion G is formed by a further longitudinal
Der Randabschnitt H wird von zwei weiteren Längsausgleichs-Rostelementen 12 gebildet, welche in zwei in Querrichtung aneinander anschließende Standard-Rostelemente 2 so weit eingeschoben sind, dass sich der deutlich größere Abschnitt der Längsträger der genannten Längsausgleichs-Rostelemente 12 zwischen den beiden Querträgern der Standard-Rostelemente 2 befinden, in welche die genannten Längsausgleichs-Rostelemente 12 eingeschoben wurden.The edge section H is formed by two further longitudinal
Ein weiteres Längsausgleichs-Rostelement 12 bildet den vergleichsweise kurzen Randabschnitt I und wiederum ein weiteres Längsausgleichs-Rostelement 12 den Randabschnitt K. Bei der Montage der Längsausgleichs-Rostelemente 12, welche die Randabschnitte H, I, K bilden, muss derart vorgegangen werden, dass zuerst das den Randabschnitt K bildende Längsausgleichs-Rostelement 12, anschließend das den Randabschnitt I bildende Längsausgleichs-Rostelement 12 und schließlich die beiden den Randabschnitt H bildenden Längsausgleichs-Rostelemente 12 in die jeweils bereits montierten Standard-Rostelemente 2 eingeschoben werden.A further longitudinal
Alle bisher erläuterten Randabschnitte A bis K werden von Rostelementen 2, 6, 12 gebildet, welche zu einem ersten Typ von Rostelementen gehören. Die im Folgenden erwähnten Randabschnitte L bis Q hingegen werden von Rostelementen 2', 6' gebildet, die zu einem zweiten Typ von Rostelementen gehören. Die Rostelemente des zweiten Typs entsprechen bis auf die Länge der jeweiligen Längsträger den Rostelementen des ersten Typs. Die Längsträger der Rostelemente 2, 6, 12 des ersten Typs sind ungefähr doppelt so lang wie die Längsträger der Rostelemente 2', 6' des zweiten Typs.All previously explained edge portions A to K are formed by
Bei den die Randabschnitte L bis P bildenden Rostelementen 2', 6' verlaufen die Längsträger senkrecht zu den Längsträgern derjenigen Rostelemente 2,6, 12, welche die Randabschnitte A bis K bilden. Dabei schließen die Rostelemente 2', 6' jedoch direkt an Rostelemente 2, 12 an, so dass zwischen den Rostelementen 2, 12 des ersten Typs und den Rostelementen 2', 6' des zweiten Typs keine Lücke existiert.In the case of the grate elements 2 ', 6' forming the edge sections L to P, the side members run perpendicular to the longitudinal members of those
Der Randabschnitt M wird von zwei Standard-Rostelementen 2' gebildet, wobei in jedes dieser beiden Standard-Rostelemente 2' auf die bereits erläuterte Weise jeweils ein Querausgleichs-Rostelement 6' eingefädelt wurde. Das den Randabschnitt L bildende Querausgleichs-Rostelement 6' wurde dabei derart in das entsprechende Standard-Rostelement 2' eingefädelt, das insgesamt drei Längsträger des Querausgleichs-Rostelements 6' zwischen den jeweiligen Längsträgern des Standard-Rostelements 2' zu liegen kommen. Das den vergleichsweise kurzen, an eine schematisch dargestellte Säule 20' anschließenden Randabschnitt N bildende Querausgleichs-Rostelement 6' ist hingegen derart angeordnet, dass sich insgesamt fünf seiner Längsträger zwischen den jeweiligen Längsträger eines Standard-Rostelements 2' befinden.The edge portion M is formed by two standard grate elements 2 ', wherein in each of these two standard grate elements 2' in the manner already explained in each case a cross compensation grate element 6 'was threaded. The cross-compensation grate element 6 'forming the edge section L was threaded into the corresponding standard grate element 2' in such a way that a total of three longitudinal beams of the transverse compensation grate element 6 'lie between the respective longitudinal members of the standard grate element 2'. On the other hand, the transverse compensation grid element 6 'which forms the comparatively short edge section N adjoining a schematically illustrated column 20' is arranged in such a way that a total of five of its longitudinal beams are located between the respective longitudinal members of a standard grid element 2 '.
Da bei der dargestellten Deckenschalung gemäß
Der Randabschnitt P wird von insgesamt fünf direkt aneinander angrenzenden Standard-Rostelementen 2' gebildet, deren Querträger stirnseitig direkt aneinander anstoßen. In das am nächsten an der Säule 20' angeordnete Standard-Rostelement 2' ist wiederum ein Querausgleichs-Rostelement 6' eingefädelt, welches den Randabschnitt O bildet.The edge portion P is formed by a total of five directly adjacent standard grate elements 2 ', the cross member abut the front side directly to each other. In the next to the column 20 'arranged standard grate element 2' is in turn a Querausgleichs grate element 6 'threaded, which forms the edge portion O.
Der an einer weiteren Säule 20 angrenzende Randabschnitt Q wird schließlich von einem weiteren Querausgleichs-Rostelement 6' des zweiten Typs gebildet, welches in ein Standard-Rostelement 2 de ersten Typs eingefädelt ist. Dies zeigt, dass auch Querausgleichs-Rostelemente des zweiten Typs in Standard-Rostelemente des ersten Typs eingebracht werden können.Finally, the edge portion Q adjoining another
