Description

Ceiling formwork system

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 of the Applicant. In this system, 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.

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 length compensation can be carried out by said intermeshing of the grate elements, which means that individual dimensions can be set in the longitudinal direction of the longitudinal members with the above-mentioned ceiling formwork system, which can be selected independently of the grid dimension of the grate elements.

An object of the invention is to develop a slab formwork system of the type mentioned in such a way that a ceiling formwork can be adapted not only in the direction of the side members, but also perpendicular thereto to individual size ratios, in particular a fast, easy and safe mounting and dismantling the slab formwork system.

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 Querausgleichs grate elements one or two have arranged in comparison to the standard grate elements offset inwardly arranged cross member.

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.

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 installing 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, cross-compensating grate 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. In this way, in a transverse direction perpendicular to the longitudinal members, individual, continuously adjustable abutments which are not bound to any spacing can be achieved. realize measurements by positioning the respectively desired number of longitudinal members of a transverse compensation grate element between each two adjacent longitudinal members of a standard grate element. 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.

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, two or more classes or types of grate elements, each having different dimensions, can be used, in which case standard grate elements and at least corresponding cross-compensating grate elements exist for each class, the side members of which have the same dimensions like 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.

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 interlock, since in this case the opposite ends of the longitudinal members of the transversal same-rust element would collide with the cross members of the standard grate element. In this case, rather, the cross-compensating 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 respectively desired number of longitudinal members of the cross-compensating 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 transverse compensation grate element can be raised above the other cross member of the standard grate element and supported thereon. The said process of filing is described in more detail in the description of the figures.

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 is a reliable fall arrest. 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.

It is particularly preferred if, in addition to the standard grate elements and the transverse compensation grate elements, the already mentioned longitudinal compensating grate elements are made available in the context of a slab formwork system according to the invention which only one or more in one of the two opposite end portions of the side members Have cross member. It is then also possible to construct slab formwork systems with such longitudinal compensation grate elements which have individual, continuously adjustable dimensions which are not bound to any grid dimension in the direction of the longitudinal members. Specifically, it is possible by the arrangement of the or the cross member in only one end of the side members, the Längsausgleichs- grate elements with their cross member or the cross members 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 rest on cross members of a standard or a transverse compensation grate element. At most, the longitudinal compensation grate elements can be inserted until their cross members or their cross members abut the cross members of a standard grate element or a cross 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 pushed in if the standard grate elements adjoining them and / or transverse grating elements same-grate elements are already mounted. It is possible that when mounted slab formwork or the cross member of a longitudinal compensation grate element with respect to the overall formwork are arranged on the outside, wherein the side members of the longitudinal compensation grate element facing inward. Alternatively, however, it is also possible to use a longitudinal compensation

Push the grate element from the underside of another grate element forth with its cross-beam-free end from the inside over a cross member of the other grate element 201, so that the side members of the longitudinal compensation grate element ultimately project outwardly beyond the cross members of the other grate element in the mounted position.

Furthermore, it is preferred 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 arranged offset inwards in one of the two end regions of the side members that are opposite each other in comparison to the longitudinal compensation grate elements , 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.

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.

It is also advantageous if Stirnabschalungsträger between the end regions of two adjacent side members can be attached to these. In this way, end formworks can then be mounted on these end formwork carriers, which extend perpendicular to the actual formwork skin and thus limit and frame a receiving area for the concrete to be applied to the formwork facing. 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.

It is particularly preferred if a side member of at least one cross-compensating 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-compensating grate element are dimensioned shorter than the distance between two cross members of a standard -Rostelements. This design of a cross-compensating grate element ensures that, during assembly, the cross-compensating grate element does not have to be threaded completely over the head into a standard grate element. Rather, it is possible, the cross-compensation grate element in a substantially vertically aligned position with Position the longer side member above a cross member of a standard grate element, then pivot it up in a further substantially vertical position and then position it with the other end of the longer side member above another cross member of the standard grate element, so that the cross member Same grate element is vertically suspended coupled to the standard grate element. Subsequently, the transverse compensation grate element can then be pivoted into a substantially horizontal position. In the latter pivoting process, at the conclusion of the fitter lately turn turn over head, then a large part of the weight of the cross compensation grate element is already taken up by the cross members of the standard grate element, so that there is a much easier handling for the fitter , The mentioned principle will be explained in more detail below with reference to FIGS. 9 to 12.

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.

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. The longitudinal extent of the longer longitudinal member of a Querausgleichs grate element may substantially correspond to the distance of the opposite 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.

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 does not take place according to the invention, since only the tops of the side members form the support surface for the formwork. 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.

Further preferred embodiments of the invention are described in the subclaims.

The invention will now be described by way of example with reference to the drawings; in these show:

11 is a view of FIG. 9 at a third assembly step, and

12 is a plan view of an arrangement of six standard

Grate elements and three cross-compensation grate elements, which were coupled together according to FIGS. 9 to 11.

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. However, the side members IO of the cross-compensation grate element are arranged offset inwards compared to the standard grate element 2 according to FIG. 1, so that ultimately they do not come to lie in the end-side end regions of the side members 8. Said offset of the cross members 10 is significantly greater than the width of the cross members 5 of the standard grate element 2, preferably the offset is approximately three times the said width (for example approximately 13 cm). As an alternative to an arrangement according to FIG. 2, it would also be possible merely to provide a single cross member, which would then also have to be arranged offset inwards in the manner mentioned. In particular, such a single cross member could also be provided centrally on the longitudinal members 8.

Fig. 3 shows a longitudinal compensation grate element 12, which in turn consists of six parallel and spaced from each other extending longitudinal beams 14 and two perpendicular thereto extending cross members 16. However, in this case, 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. Instead of the two transverse beams 16 shown in FIG. 3, only one such transverse beam 16 can be used, but the embodiment with two transverse beams 16 is advantageous in terms of the stability of the longitudinal compensation grid element 12. The mutual distance between adjacent side members 4, 8, 14 is equal in all grate elements 2, 6, 12. Likewise, all the longitudinal members 4, 8, 14 of all grate elements 2, 6, 12 each have the same length. This results in that of the totality of the longitudinal members 4, 8, 14 of a grate element 2, 6, 12 each with each other equal areas can be covered. Ultimately, therefore, all the grate elements 2, 6, 12 have mutually equal sizes.

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.

Both for the longitudinal members 4, 8, 14 and for the cross members 5, 10, 16 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.

In the case of all the grate elements 2, 6, 12, 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. If a cross-compensating grate element 6 is to be coupled to an already mounted standard grate element 2, a respectively desired number of longitudinal members 8 of the cross-compensation grate element 6 is threaded between respectively adjacent longitudinal members 4 of a standard grate element 2, according to FIG the ends of the threaded side members 8 of the transverse compensation grate element 6 are located above a cross member 5 of the standard grate element 2. This position is shown in Fig. 4a. Starting from this position, 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 -Rostelements 2. This position is shown in Fig. 4b. According to FIG. 4b, it is clear that the side members 4, 8 of the two grate elements 2, 6 do not terminate flush with one another at this stage of assembly, but instead collar the ends of the side members 8 of the cross-compensation grate element 6 over the ends of the side members 4 of the standard frame. Rust element 2 addition.

Starting from this position, shown in FIG. 4b, the transverse compensation grate element 6 is then linearly displaced in the direction of the arrow according to FIG. 4b until the end faces of the side members 4, 8 of both grate elements 2, 6 are aligned with one another, as shown in FIG. 4c is. Due to the inwardly offset arrangement of the cross member 10 on the cross compensation grate element 6, the threading described in connection with FIG. 4 a cross compensation grate element 6 in a standard grate element 2 is possible without the cross member 5, 10 of both grate elements 2, 6 together collide.

5 shows a plan view of a completely assembled slab formwork system according to the invention, which grate elements are secondarily different Types in two different sizes. The different sizes of the grate elements 2, 6, 12 on the one hand and 2 ', 6' on the other hand are realized in that the side members of said grate elements have different lengths. Specifically, the length of the longitudinal members of the grate elements 2 ', 6' is approximately half the length of

Side member of the grate elements 2, 6, 12. The distance between adjacent side members is the same for all grate elements 2, 6, 12, 2 ', 6'. All grate elements 2, 6, 12, 2 ', 6' each have six longitudinal members, which means that all grate elements 2, 6, 12, 2 ', 6' have the same widths.

The slab formwork according to FIG. 5 adjoins a wall 18, which consists of a total of seven sections arranged at right angles to one another. Furthermore, the slab formwork system shown also connects to two free-standing columns 20, 20 ', which are arranged at a distance from the wall 18.

For simpler explanation of the construction of the slab formwork system according to FIG. 5, the adjoining edge sections of the slab formwork system are designated by consecutive letters, to which reference is made below.

The base of the slab formwork system according to FIG. 5 is formed by a total of sixteen adjoining standard grate elements 2, which are arranged in a 4x4 matrix and thus cover the largest part of the surface of the slab formwork system according to FIG. 5. Five of these standard grate elements 2 form the edge sections A and B.

In the area of the edge section C, two transverse compensation grate elements 6 adjoining one another in the direction of the longitudinal members are provided, which are meshed with a standard grate element 2 in each case by the transverse compensation grate elements 6 according to FIG. 4 were threaded into the standard grate elements 2. Regarding both cross-compensating grate elements 6, two longitudinal members each come to rest between adjacent longitudinal members of the respective standard grate elements 2.

The edge sections D and F are formed by a longitudinal compensation grate element 12, which is inserted into a cross compensation grate element 6 so far that the free ends of the side members of the longitudinal compensation grate element 12 are mounted on a cross member of the transverse compensation grate element 6 support. Three longitudinal members of the longitudinal compensation grate element 12 come to rest between in each case two adjacent longitudinal members of the transverse compensation grate element 6, whereas the three other longitudinal members of the longitudinal compensation grate element 12 are each connected between a longitudinal support of the transverse compensation grate element 6 and a longitudinal support of that standard. Rust element 2 come to rest, which is interlocked with that cross-compensating grate element 6, supported on the cross member, the longitudinal members of the longitudinal compensation grate element 12.

The edge section G is formed by a further longitudinal compensation grate element 12, which is inserted into the longitudinal compensation grate element 12 with respect to the edge section D with two longitudinal members so far that the cross members of the two longitudinal compensation grate elements 12 contact one another in sections come. The free ends of the edge portion G forming longitudinal compensation grate element 12 are supported on a cross member of that standard grate element 2, which is interlocked with the part of the edge portion C forming Querausgleichs grate element 6. The edge section H is formed by two further longitudinal compensation grate elements 12, which are inserted so far into two standard grate elements 2 adjoining one another in the transverse direction, that the significantly larger section of the side members of said longitudinal compensating grate elements 12 is between the two Cross members of the standard grate elements 2 are located, in which said Längsausgleichs- grate elements 12 were inserted.

A further longitudinal compensation grate element 12 forms the comparatively short edge section I and again a further longitudinal compensation grate element 12 the edge section K. When assembling the longitudinal compensation grate elements 12 which form the edge sections H, I, K, it is necessary to proceed in such a way that first the longitudinal compensation grating element 12 forming the edge section K, then the longitudinal compensation grate element 12 forming the edge section I and finally the two longitudinal compensation grate elements 12 forming the edge section H are inserted into the respectively already mounted standard grate elements 2.

All previously explained edge portions A to K are formed by grate elements 2, 6, 12, which belong to a first type of grate elements. On the other hand, the edge portions L to Q mentioned below are formed by grate elements 2 ', 6' belonging to a second type of grate elements. The grate elements of the second type correspond to the length of the respective side members of the grate elements of the first type. The longitudinal beams of the grate elements 2, 6, 12 of the first type are approximately twice as long as the longitudinal beams of the grate elements 2 ', 6' of the second type.

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 grate elements 2, 6, 12 which form the edge sections A to K. Close it However, the grate elements 2 ', 6' directly to grate elements 2, 12, so that there is no gap between the grate elements 2, 12 of the first type and the grate elements 2 ', 6' of the second type.

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 transverse compensating 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 members of the transverse compensating grate element 6 'lie between the respective longitudinal members of the standard grate element 2'. By contrast, the transverse compensating grate element 6 'forming the comparatively short edge section N adjoining a schematically illustrated column 20' is arranged such that a total of five of its longitudinal members are located between the respective longitudinal members of a standard grate element 2 '.

Since in the illustrated slab formwork according to FIG. 5 the distance between two adjacent longitudinal members of a grate element corresponds to three times the width of the side members, cross-compensating grate elements threaded in standard grate elements can still be up to twice as large in a direction perpendicular to their longitudinal members Width of the side members are moved, so as ultimately to achieve a fine-tuning in the cross-compensation to be achieved. Thus, for example, from Fig. 5 it can be seen that the longitudinal beams of that cross-compensating grate element 6 ', which forms the edge portion N, approximately in the middle between two adjacent longitudinal members of the respective standard grate element 2' are, whereas the side members of the cross-compensating grate element 6 ', which forms the edge portion L, directly to the respective longitudinal members of the associated standard grate element 2 'rest.

The edge section P is formed by a total of five standard grate elements 2 ', which adjoin one another directly adjacent to one another and whose transverse supports abut the end faces directly against one another. 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.

Finally, the edge portion Q adjoining another column 20 is formed by another cross-compensating grate element 6 'of the second type, which is threaded into a standard grate element 2 of the first type. This shows that cross balancing grate elements of the second type can also be incorporated into standard grate elements of the first type.

6a, b show an already mounted standard grate element 2 with longitudinal members 4 and cross members 5, in which according to FIG. 6a a longitudinal compensation grate element 12 is threaded from below in such a way that first the free ends of the longitudinal members 14 of the longitudinal compensation -Rostelements 12 inserted between the longitudinal members 4 of the standard grate element 2 and then pushed over a cross member 5 of the standard grate element 2 and finally pivoted so that ultimately the longitudinal members 14 of the longitudinal compensation grate element 12 of FIG. 6b on the side members 4 of Standard rust element 2 collar out. In the fully assembled position according to FIG. 6b, the upper side of the cross member 16 of the longitudinal compensation grid element 12 rests on the lower side of the longitudinal members 4 of the standard grid element 2. In this way it is ensured that when pressure is applied to the cantilevers beyond the longitudinal members 4 out Ends of the longitudinal members 14 of the longitudinal compensation grate element 12, no tilting of the same can take place.

FIG. 7 shows a combi-compensation grate element 22, the shape of which essentially corresponds to that of a longitudinal compensation grate element 12 according to FIG. 3. The only difference is that the cross member 26 of the combi-compensation grate element are arranged offset relative to a longitudinal compensation grate element 12 inwardly, said offset can correspond to the extent to which the cross member 10 of a cross compensation grate element 6 are offset inwards. A combi-compensation grate element 22 may alternatively be equipped with only one cross member 26.

FIG. 8 shows the manner in which a combi-compensation grate element 22 according to FIG. 7 can be used in order to simultaneously realize a longitudinal compensation and a transverse compensation.

According to FIG. 8, the longitudinal members of a longitudinal compensation grate element 12 are pushed into a standard grate element 2 so far that the longer region of the longitudinal members of the longitudinal compensation grate element 12 is located between the longitudinal members of the standard grate element 2. Furthermore, in the standard grate element 2, a transverse compensation grate element 6 has been threaded in such a way that two side members of the cross compensation grate element 6 are located approximately centrally between longitudinal members of the standard grate element 2. Thus, 12 individual dimensions in the direction of the longitudinal beams of the standard grate element 2 are realized by the longitudinal compensation grate element, whereas individual dimensions are realized perpendicular thereto with the cross-compensating grate element 6. In order ultimately to create a total rectangular grate surface with individual length and individual width, it is necessary to use in the already explained arrangement of FIG. 8, a combi-balance grate element 22. The free ends of the side members of such a combi-compensation grate element 22 are first moved from below between the longitudinal members of the longitudinal compensation grate element 12 and then pushed over the respective cross member of the standard grate element 2 and the cross compensation grate element 6 until the combination compensation -Rostelement 22 can be pivoted in the plane in which the already mounted grate elements 2, 6, 12 are arranged. After this pivoting, a cross member of the combination compensation grate element 22 abuts in sections on a cross member of the longitudinal compensation grate element 12. Due to the fact that the cross members of the combination compensation grate element 22 are offset inwards relative to the cross members of the longitudinal compensation grate element 12, it is possible to position the longitudinal compensation grate element 12 and combination grate element 22 in such a way that their respective side members are aligned flush with one another.

Fig. 9 shows a three-dimensional view of a standard grate element 2, which is supported on the bottom side in its four corner regions via a respective vertical support 28. The standard grate element 2 according to FIG. 9 is thus in a horizontal orientation.

Furthermore, FIG. 9 shows a preferred transverse compensation grate element 30, which consists of six shorter longitudinal members 32, a longer side member 34 and two cross members 10 supporting the side members 32, 34 from below. The cross member 10 extend perpendicular to the longitudinal members 32, 34 and are arranged offset from the end faces of the shorter side member 32 slightly inwardly. The shorter longitudinal members 32 are dimensioned shorter than the distance between the facing each other. The inner side of the cross member 5 of the standard grate element 2. The longer side member 34 has approximately the same length as the side members 4 of the standard grate element. 2

Due to the stated arrangements and dimensions, it is possible to position the one end of the longer side member 34 above a cross member 5 of the standard grate element 2 in the case of a substantially vertical alignment of the transverse compensation grate element 30 shown in FIG. Subsequently, the transverse compensation grate element 30 can then be pivoted upward while continuing to be substantially vertically aligned and then displaced so far in the longitudinal direction of the longer side member 34 until the other end of this longitudinal support 34 comes to rest above the other cross member 5 of the standard grate element 2 , as shown in Fig. 10. In this position, the cross-compensating grate element 30 with its side member 34 hangs substantially vertically downwards on the standard grate element 2.

Starting from the position according to FIG. 10, the transverse compensation grate element 30 can then be pivoted upwards about the longitudinal axis of the longitudinal member 34, as illustrated by the arrow shown in FIG. 11. With a continued pivoting up of the transverse compensation grate element 30 in the arrow direction of FIG. 11, the upper sides of the cross members 10 of the transverse compensation grate element 2 ultimately abut the lower sides of the side members 4 of the standard grate element 2, so that then both the standard grate element 2 and the cross-compensation grate element 30 are in a common plane in a substantially horizontally oriented position.

The latter position is illustrated in FIG. 12, according to which three transverse compensation grate elements 30 with three standard grate elements 2 are provided. are coupled, this coupling was accomplished in accordance with the method steps described in connection with FIGS. 9 to 11.

It is readily apparent that the last-described coupling method is easier to handle for an installer than the simultaneous overhead threading of all side members 8 of a cross-compensation grate element 6 according to FIG. 2.
