Description

[0001] Formwork table element, formwork table and method for erecting a slab formwork

[0002] The invention relates to a formwork table element, comprising: at least one formwork panel, at least one longitudinal beam and a plurality of cross beams which support the at least one formwork panel.

[0003] Furthermore, the invention relates to a formwork table, comprising: a formwork table element, at least one formwork support with a support element and with a support head.

[0004] Finally, the invention relates to a method for constructing a ceiling formwork.

[0005] As described in EP 1 538 278 A2, for concreting a floor slab of a concrete structure, an essentially horizontally arranged formwork skin can be created, the edges of which are defined by stop end formwork. In the prior art, it was already known to form the formwork skin from a large number of formwork panels placed on cross girders, which in turn are placed perpendicular to them on longitudinal or main beams. The main beams are supported by floor props towards the ground. In this prior art, the load from the formwork skin was transferred via a structure of cross girders and main beams placed on top of one another in two planes. EP 1 538 278 A2, on the other hand, relates to prefabricated formwork units made up of formwork panels, cross girders and main beams, which can be moved between floors in a time-saving manner. Wooden cross girders are attached to the back of the formwork panels. Below the cross members there are longitudinal and lateral sections.Steel yoke beams. To attach the cross beams to the longitudinal beams, connecting straps are welded to the U-profiles of the yoke beams. The supports can be attached to these yoke beams. For this purpose, holes are provided at regular intervals along the longitudinal beams or yoke beams, to which the support head holders can be attached using bolts. The support heads are designed as swivel heads, with which the supports can be swiveled to the side. A disadvantage, however, is that the longitudinal beams or yoke beams are arranged close to the long edges of the formwork panel, which means that the floor props cannot be attached to the long edges in many applications with limited space, for example when concreting cantilevered concrete elements such as balcony slabs. With the current state of the art, this problem had to be circumvented at great expense using intermediate bars which were inserted under the longitudinal beams or yoke beams.The yoke beams were arranged parallel to the cross beams. However, this results in a supporting structure with three levels, consisting of the cross beams, the longitudinal beams or yoke beams, and the intermediate beams. This supporting structure is not only complex to prepare, but also results in a very high structure, which is disadvantageous in many applications.

[0006] FR 3 027 932 A1 shows another pre-assembled formwork table in which the yoke and cross beams are arranged one above the other in two levels. In this prior art, the floor props are connected to the yoke beams. The cross beams can be connected to the yoke beams at different longitudinal positions. Using individual holes, the yoke beams, including supports and heads, can be adjusted relative to the cross beams. This means that the statics of the structure can be influenced. However, the operating effort is high. In addition, this prior art does not offer the desired variability. In contrast, the object of the present invention is to alleviate or eliminate at least certain disadvantages of the prior art. The invention preferably aims to expand the possible uses of formwork tables of this type.

[0007] This object is achieved by a formwork table element according to claim 1, a formwork table according to claim 10 and a method according to claim 15. Preferred embodiments are specified in the dependent claims.

[0008] According to the invention, the at least one longitudinal beam and the plurality of cross beams are arranged overlapping in the direction perpendicular to the main extension plane of the formwork panel (i.e. in the vertical direction when the formwork panel is aligned horizontally), wherein the at least one longitudinal beam and the plurality of cross beams each have connecting elements for connection to a support head of a formwork support.

[0009] In contrast to the prior art, the at least one longitudinal beam and the cross beams are not arranged entirely on top of one another, but overlapping, i.e. at least in sections at the same height. The cross beams therefore cross the at least one longitudinal beam, preferably substantially at a right angle. The at least one longitudinal beam and the cross beams form a supporting structure for the formwork panel. The cross beams are preferably fixedly connected to the at least one longitudinal beam, for example via welded joints. Connecting elements for connecting formwork supports are provided on both the at least one longitudinal beam and the cross beams. Advantageously, individual formwork supports can therefore be mounted optionally on the longitudinal and / or the cross beams. This variability can be used, for example, to arrange the formwork support offset from an outlet in the support area.Furthermore, the static requirements can be precisely adjusted. For example, the formwork table element can be specifically supported with additional formwork props in places where there are larger accumulations of concrete, such as in the case of ceiling jumps. Even where standing areas are limited and when concreting cantilevered ceiling elements, such as balcony slabs, it is advantageous that the formwork props can be mounted either on the longitudinal and / or the cross beams. Another advantage is that the assembly height can be reduced compared to the state of the art due to the overlapping arrangement of the longitudinal and cross beams. The reduced loading volume also makes transport easier.

[0010] For the purposes of this disclosure, the location and direction information refers to the intended use of the formwork table element with the formwork panel aligned horizontally. Of course, the formwork panel can also be arranged inclined to the horizontal, in which case the location and direction information must be transferred accordingly.

[0011] Depending on the design, the formwork panel can be connected to the longitudinal and / or cross beams using rivets, screws or adhesives.

[0012] For effective dissipation of the concrete forces, it is advantageous if the preferably substantially flat upper sides of the longitudinal and transverse beams are each arranged substantially in the same plane, parallel to the main extension plane of the formwork panel. The underside of the formwork panel preferably rests against the upper sides, i.e., the sides facing the formwork panel, of the at least one longitudinal beam and the plurality of transverse beams.

[0013] In order to connect identical formwork supports, it is advantageous if the connecting elements of the at least one longitudinal beam are arranged at a first distance from the preferably substantially flat underside of the at least one longitudinal beam and the connecting elements of the cross beams are arranged at a second distance from the preferably substantially flat undersides of the plurality of cross beams, wherein the first and the second distance are substantially identical. The first and the second distance refer to the distance perpendicular to the main extension plane of the formwork panel, i.e., when the formwork panel is aligned horizontally, to the vertical distances. In this embodiment, the undersides of the longitudinal and the cross beam can each be designed as support surfaces for the support head of the formwork support.Thanks to the identical distances from the undersides to the connection openings, the same formwork prop can be connected either to the longitudinal beam or to one of the cross beams, even in a design in which the longitudinal beam and the cross beams are of different heights, i.e. have different extensions perpendicular to the main extension plane of the formwork panel. When using a telescopic prop as a formwork prop, the telescopic prop in this design can be extended to different lengths depending on whether the telescopic prop is connected to the longitudinal beam or to one of the cross beams. It is important that the same formwork prop can be used regardless of whether it is attached to the longitudinal beam and / or to one of the cross beams.

[0014] In a preferred embodiment, the at least one longitudinal beam and the plurality of cross beams each have identical connecting elements for connection to the support head of the formwork support. Advantageously, in this embodiment, the same formwork support can be connected optionally to a longitudinal and / or cross beam.

[0015] For the variable, secure and simple connection of formwork supports to the formwork table element, it is advantageous if connection openings, in particular passage openings, are provided as connecting elements for the longitudinal and / or transverse beams. In this embodiment, at least one longitudinal and several transverse beams are provided on the back of the formwork panel, preferably each with connection openings which are designed for connecting formwork supports. In order to reversibly detachably connect a formwork support to the formwork table element at the desired position, the connector of the support head is connected, depending on the design, directly or via a connecting element, in particular via a connecting bolt, to at least one of the connection openings of one of the longitudinal and / or transverse beams. When the formwork support is mounted on the longitudinal or transverse beams, the formwork support is in the assembled state.The column head is fixed in position relative to the formwork table element using the cross beam.

[0016] Preferably, the connecting openings are designed as through-openings which completely penetrate the longitudinal and transverse beams, each transverse to their longitudinal direction. The through-opening is designed to receive, in particular to insert, a connecting element, in particular a connecting bolt, with which the connector of the support head can be engaged.

[0017] Alternatively, the connecting openings can be designed as connecting grooves of the longitudinal and transverse beams. An element other than the formwork support, such as a railing adapter or a platform, can also be connected to one of the connecting openings.

[0018] Preferably, the at least one longitudinal member and the transverse member each have at least 3, preferably at least 5, in particular at least 10, connecting openings, in particular passage openings, which are preferably arranged at equal intervals along the respective longitudinal or transverse member.

[0020] The longitudinal beam and / or the cross beams and / or the surrounding frame are preferably made of metal, in particular steel. The formwork panel preferably has a panel element, in particular made of wood and / or plastic. The outer side of the formwork panel is designed as a formwork plane, which delimits the space to be filled with concrete. The panel element is preferably reversibly and detachably connected to the surrounding frame.

[0021] The longitudinal and transverse members are preferably fixedly connected to the longitudinal and transverse frame parts of the surrounding frame.

[0022] In order to ensure the desired stiffening on the one hand and to create a variety of connection options for formwork supports on the other hand, the at least one longitudinal beam extends from one cross frame part to the other cross frame part of the surrounding frame. Preferably, at least two longitudinal beams, in particular exactly two longitudinal beams, are provided, which are arranged in particular parallel to one another and parallel to the longitudinal frame parts. To create connection options for formwork supports, in particular also in a central region of the formwork table element, in relation to the two long sides of the formwork panel, it is advantageous if at least two cross beams, preferably more than four cross beams, in particular more than six cross beams, each with connecting openings for the support head are provided between the two cross frame parts, the cross beams each extending from one longitudinal frame part to the other longitudinal frame part.Preferably, the cross members are arranged parallel to each other and parallel to the cross frame parts of the surrounding frame.

[0023] In a preferred embodiment, at least one formwork support is mounted on one of the longitudinal and / or transverse beams. It is particularly preferred if a formwork support is mounted at an intersection point between one of the transverse beams and one of the longitudinal beams.

[0024] In order to be able to use a number of identical formwork supports with the same length or, in the case of a telescopic support, in the same extension position for supporting the formwork table element, it is advantageous if the longitudinal and transverse beams each have essentially the same height and / or the same width. The height refers to the extension in the direction perpendicular to the main extension or panel plane of the formwork panel. The width refers to the extension in the direction perpendicular to the longitudinal direction of the longitudinal or transverse beams parallel to the main extension or panel plane.

[0025] Panel plane of the formwork panel. In this design, the undersides of the longitudinal and transverse beams are preferably arranged essentially in the same plane, parallel to the formwork skin.

[0026] In a preferred embodiment, the connecting elements, in particular the connecting openings (relative to their centers) are arranged substantially at the same height, i.e. in the same plane parallel to the concrete-facing outer side, i.e. the formwork skin, of the formwork panel.

[0027] Preferably, the longitudinal and transverse beams each have a height of at least 70 mm, in particular of at least 80 mm, preferably of 90 mm to 110 mm and / or a width of at least 40 mm, in particular of at least 50 mm, preferably of 60 mm to 70 mm.

[0028] The formwork table according to the invention comprises the formwork table element in one of the embodiments described above and at least one formwork support, preferably several, in particular identical, formwork supports, wherein the support head of the at least one formwork support has at least one connector for connection to one of the connecting elements of the longitudinal and transverse beams. Depending on the application, for example, at least two, in particular at least three, preferably at least four, formwork supports can be provided, each of which is connected to one of the longitudinal and / or transverse beams.

[0029] The support element of the formwork prop is preferably designed as a length-adjustable telescopic element, in particular with an inner part, preferably an inner tube, and with an outer part, in particular an outer tube. In the support position for concreting the concrete element, the longitudinal axis of the support element is preferably aligned substantially vertically.

[0030] For many applications of the formwork table, for example as a balcony table, it is advantageous if at least one formwork support is connected to one of the cross beams. It is preferred if several formwork supports are connected to several cross beams, which are spaced apart from one another in the longitudinal direction of the formwork table element. It is particularly preferred if several formwork supports are each connected to several cross beams, i.e. a pair of formwork supports or more than two formwork supports are each connected to several cross beams.

[0031] In a preferred embodiment, at least one connecting bolt is provided which connects the at least one connector of the support head to the connecting element of the longitudinal or transverse beam. The connector preferably has at least one hook element with a hook opening. The connector preferably has two hook elements which are designed to grip the ends of the connecting bolt projecting through the connecting opening. The connector preferably has two hook connectors, each with two hook elements. One of the two hook elements is hooked to the projecting ends of the connecting bolt. The other two hook elements are hooked to the projecting ends of a further connecting bolt which is pushed through another of the connecting openings.

[0032] Alternatively, at least one tab element with a tab opening closed all around can be provided as a connector.

[0033] In a preferred embodiment, the support head has a holder having the connector and a head part connected to the support element, wherein the head part is pivotably connected to the holder via an articulated connection, in particular between an upright, preferably substantially vertical, support position and at least one horizontal transport position. In this embodiment, the support head is designed as a pivot head, with which the support element can be pivoted sideways.

[0034] In a preferred embodiment, a securing device is provided for selectively blocking and releasing the pivoting of the head section relative to the support head holder, particularly in the upright support position and in the horizontal transport position. The securing device can have a securing lever. The securing lever can have a securing lug which engages behind a retaining pin of the head section in the support position. The securing lever can have a further securing lug with which the formwork support is locked in the horizontal transport position, preferably by engagement with a further retaining pin of the head section.

[0035] In a preferred embodiment, the articulated connection of the support head is designed such that, when the formwork support is mounted on one of the cross beams, the support element extends along the cross beam in the lying transport position and / or that, when the formwork support is mounted on one of the longitudinal beams, the support element extends along the longitudinal beam in the lying transport position. For this purpose, the articulated connection can have an articulated axis which, with reference to the mounted state of the formwork support, extends perpendicular to the longitudinal direction of the longitudinal or cross beam. Preferably, the articulated connection allows pivoting exclusively about the articulated axis transverse to the longitudinal direction of the longitudinal or cross beam.

[0036] For the reversibly detachable assembly of the formwork support, the support element in a preferred embodiment has a head plate which is detachably connected to the support head, in particular by means of a wedge element.

[0037] The method according to the invention for constructing a ceiling formwork comprises at least the following steps:

[0039] Providing a formwork support with a support element and with a support head in one of the embodiments described above, wherein the support head has at least one connector, and

[0040] Connecting the connector of the column head to one of the connecting elements of the longitudinal and / or cross beams.

[0041] To install the formwork support on one of the longitudinal or transverse beams, the following steps are preferably carried out, particularly in the specified order:

[0042] Arranging a connecting bolt at a connecting opening of the longitudinal or cross member, connecting a first pair of hook connectors with ends of the connecting bolt projecting laterally from the longitudinal or cross member,

[0043] Arranging hook openings of a second pair of hook connectors in alignment with a further connecting opening of the longitudinal or cross member, and arranging a further connecting bolt at the further connecting opening of the longitudinal or cross member and at the hook openings of the second pair of hook connectors.

[0044] Preferably, the method comprises connecting a plurality of connectors of a plurality of support heads to a plurality of longitudinal and / or transverse beams.

[0045] The invention is explained in more detail below with reference to embodiments shown in the drawings.

[0046] Fig. 1 shows a diagrammatic view of a formwork table according to the invention, in which the formwork table element carrying the formwork panel has intersecting longitudinal and transverse beams which enable a variable arrangement of formwork supports.

[0050] Fig . 7 shows a detail of the connection of the formwork support to the longitudinal beam in the upright support position .

[0051] Fig. 8 shows a view corresponding to Fig. 7 of the connection of the formwork support to the longitudinal beam in the lying transport position.

[0052] Fig. 9 shows schematically a further embodiment in which the longitudinal member is higher than the cross member.

[0053] Fig. 1 shows a formwork table 1 for concreting a slab element. The formwork table 1 has a formwork table element 2, which is supported on several formwork supports 3, four in the example shown. The number of formwork supports 3 can be varied depending on the application. The formwork table element 2 has a surrounding frame 4, which carries at least one rectangular formwork panel 5, which has a coating for contact with the concrete, at least on the upper side. The surrounding frame 4 is composed of two transverse frame parts 6 and two longitudinal frame parts 7, which form a rectangular frame for the formwork panel 5. For this purpose, the longitudinal frame parts 7 and the transverse frame parts 6 have upstanding frame noses, which enclose the formwork panel 5 on the inside. The transverse frame parts 6 form the shorter transverse sides of the formwork table element 2. The longitudinal frame parts 7 form the longer longitudinal sides of the formwork table element 2.For example, the transverse frame parts 6 can have a length of 0.5 meters (m) to 4.0 m, in particular from 1.5 m to 3.0 m, and the longitudinal frame parts can have a length of 1.0 m to 10 m, in particular from 2.5 m to 7.0 m. In the embodiment shown, the formwork table element 2 has two longitudinal beams 8 between the two longitudinal frame parts 7. The longitudinal beams 8 extend over the length of the formwork table element 2 from the inside of one transverse frame part 6 to the inside of the other transverse frame part 6. In addition, a plurality of transverse beams 9 are provided between the two transverse frame parts 6. The transverse beams 9 extend across the width of the formwork table element 2 from the inside of one longitudinal frame part 7 to the inside of the other longitudinal frame part 7, wherein the transverse beams 9 are each interrupted at the intersections with the longitudinal beams 8. In the embodiment shown, the longitudinal beams 8 and the cross beams 9 each have essentially the same height, ieExtension perpendicular to the formwork panel 5, and essentially the same width, i.e., extension perpendicular to the longitudinal direction of the respective longitudinal beam 8 or transverse beam 9 parallel to the main extension or panel plane of the formwork panel 5. In the example shown, the longitudinal beams 8 are designed as single profiles and the transverse beams 9 are designed as double profiles. The surrounding frame 4, the longitudinal beams 8, and the transverse beams 9 are fixed in position relative to one another. Thus, the surrounding frame 4, the longitudinal beams 8, and the transverse beams 9 form a rigid supporting or stiffening structure for the formwork panel 5.

[0054] As can be seen from Fig. 1, the longitudinal beams 8 and the cross beams 9 are arranged so as to overlap in the direction perpendicular to the formwork panel 5 and are arranged at the same height in the example shown. In the example shown, the undersides of the longitudinal beams 8 facing away from the formwork panel 5 and the undersides of the cross beams 9 facing away from the formwork panel 5 are arranged substantially at the same distance from the formwork plane of the formwork panel 5 when viewed perpendicular to the main extension plane of the formwork panel 5, i.e. in the vertical direction in the arrangement shown, substantially the same distance from the formwork plane of the formwork panel 5. In the example shown, moreover, the undersides of the cross frame parts 6 and the undersides of the longitudinal frame parts 7 are arranged at the same height as the undersides of the longitudinal beams 8 and cross beams 9.

[0055] According to the invention, both the longitudinal beams 8 and the cross beams 9 each have connecting elements 10, each of which is designed to be connected to a respective support head 11 of the formwork support 3. Thus, formwork supports 3 can be connected at various points of the supporting structure comprising the longitudinal beams 8 and the cross beams 9.

[0056] A plurality of connecting openings 12 are provided as connecting elements 10 of the longitudinal beams 8 and transverse beams 9, which are distributed at a distance from one another along the longitudinal beams 8 and transverse beams 9. In the exemplary embodiment shown, the connecting openings 12 are arranged at the same height, i.e., the centers of the connecting openings 12 are arranged in the same plane parallel to the main extension plane of the formwork panel 5. In the example shown, individual passage openings are provided as connecting openings 12. The passage openings can, for example, be designed with a circular cross-section or as pear-shaped slot openings.

[0057] 1 and 3 and in detail from fig. 7 and 8, the support head 11 in the example shown is designed as a pivoting head with a holder 13 and a head part 14, which are connected to one another via an articulated connection 15 with an articulated axis 16. In the assembled state, the holder 13 is immovably attached, here to one of the longitudinal beams 8. For this purpose, the holder 13 has two connectors 17, which in the example shown are designed as pairs of hook connectors. During assembly, a connecting bolt 18 is inserted through the connecting opening 12 and, in the embodiment shown, is secured with at least one securing element, in particular a securing split pin, to prevent it from slipping out of the connecting opening 12. The first pair of hook connectors is then brought into engagement with the ends of the connecting bolt 18 projecting laterally from the longitudinal beam 8.Subsequently, the hook openings of the second pair of hook connectors are aligned with another of the connecting openings 12. Another connecting bolt 18 is inserted through the other of the connecting openings 12 and the hook openings of the second pair of hook connectors. As a result, the bracket 13 of the support head 11 is held to two adjacent connecting openings 12 of the longitudinal beam 8 via the two connecting bolts 18 and blocked against movement in all directions.

[0058] With the help of the articulated connection 15, the formwork prop 3 can be pivoted from the support position shown in Fig. 1 and Fig. 7 into the transport position shown in Fig. 3 and Fig. 8. For this purpose, a locking device 19 is actuated, which blocks the head part 14 in the support position against pivoting in the direction of the transport position. In the example shown, the locking device 19 has a locking lever 20 with a locking lug 21, which engages behind a retaining pin 22A of the head part 14 in the support position, so that pivoting of the head part 14 about the articulated axis 16 is blocked. In the example shown, the holder 13 also has a bearing element 23, here a bearing bolt or a bearing screw, which is received in a recess 24 of the head part 14 in the support position. The safety lever 20 is pivotally mounted on the bracket 13 about a pivot axis 25, here the bearing element 23.By lifting the safety lever 20, the engagement of the safety lug 21 with the holding pin 22A is released, whereby the head part 14 together with the support element 26 fastened thereto can be pivoted, in particular by more than 45°, preferably by more than 60°. In the example shown, the safety lever 20 has a further safety lug 27 which, in the lying transport position, engages with a further holding pin 22B of the head part 14, so that the head part 14 is secured against pivoting back into the upright support position. In the example shown, the safety lever 20 has a safety projection 33, with which the further holding pin 22B can be locked in a further lying transport position (not shown), which is pivoted further than the lying transport position relative to the support position.For example, the horizontal transport position can be achieved by pivoting through substantially 80° relative to the support position, and the further horizontal transport position can be achieved by pivoting through substantially 90° relative to the support position. To move from the (further) horizontal transport position to the support position, the formwork prop 3 is slightly raised, the locking lever 20 is extended, and the formwork prop is pivoted into the upright support position and locked.

[0059] The support element 26 has a head plate 28 (not visible here) which is reversibly and detachably connected to the head part 14 of the support head 11 by means of a wedge element 29, here a double wedge.

[0060] Fig. 2 shows the use of the formwork table 1 for concreting a horizontal ceiling element, in this case a balcony slab. In the example shown, the formwork table 1 is erected on a lower balcony slab 30 below the balcony slab to be concreted. Due to the limited space available, in this application the formwork supports 3 cannot be arranged below the outer of the two longitudinal beams 8, which runs further outwards than the free longitudinal edge of the lower balcony slab 30. The formwork table 1 according to the invention now makes it possible to connect individual formwork supports 3 to the cross beams 9, which are arranged at the same height as the longitudinal beams 8, but extend transversely thereto.Thus, the transverse cross beams 9 can be used for the attachment of formwork supports 3, which previously had to be arranged on separate intermediate beams, which, however, disadvantageously increased the overall height of the stiffening structure below the formwork panel 5. Fig. 2 also shows inclined supports 32, which serve to absorb horizontal loads occurring during concreting.

[0061] Fig. 3 shows the lifting of the formwork table 1 from a concrete slab (here with a parapet at the slab edge) using a lifting device 31, in this case a table fork. The formwork supports 3 are arranged in the transport position, in which the formwork supports 3 are folded at a shallow angle, thus preventing a collision of the formwork table 1 with the structure.

[0062] Figs. 4 to 6 illustrate the variable arrangements of the formwork or ceiling supports 3 on the stiffening structure, which is formed from the longitudinal beams 8 and transverse beams 9.

[0063] In the example of Fig. 4, two formwork supports 3 are arranged on each of the longitudinal beams 8. The formwork supports 3 are folded into the horizontal transport position, in which the elongated support elements 26 of the formwork supports 3 are each extended along the longitudinal beam 8 on which the respective formwork support 3 is mounted. In this embodiment, the joint axis 16 of the joint connection 15 of the support head 11 extends, in the mounted state of the formwork support 3 on the longitudinal beam 8, perpendicular to the longitudinal direction of the rectilinear longitudinal beam 8. As a result, the head part 14 with the support element 26 is pivoted in a plane perpendicular to the cross beams 9. In the example shown, two formwork supports 3 are mounted on the longitudinal beams 8 at a distance from one another in the longitudinal direction of the formwork table element 2.

[0064] In the example of Fig. 5, two formwork supports 3 are arranged on two cross beams 9 which are spaced apart from one another in the longitudinal direction of the formwork table element 2. The formwork supports 3 are folded into the horizontal transport position, in which the elongated support elements 26 of the formwork supports 3 extend along the cross beam 9 on which the respective formwork support 3 is mounted. The hinge axis 16 of the hinged connection 15 of the support head 11 extends, in the mounted state of the formwork support 3 on the cross beam 9, perpendicular to the longitudinal direction of the rectilinear cross beam 9. As a result, the head part 14 with the support element 26 is pivoted in a plane perpendicular to the longitudinal beams 8. In the example shown, two formwork supports 3 are mounted on the cross beams 9 at a distance from each other in the transverse direction of the formwork table element 2.One formwork prop 3 is mounted between the two longitudinal beams 8 on the cross beams 9. The other formwork prop 3 is mounted at the intersection points of the cross beams 9 and the longitudinal beams 8. As a result, the first pair of hook connectors is arranged on one side of the longitudinal beam 8 and the second pair of hook connectors is arranged on the other side of the longitudinal beam 8. This arrangement is particularly advantageous from a structural point of view.

[0065] In the example of Fig. 6, two formwork supports 3 are mounted on two cross beams 9 and two formwork supports 3 are mounted on one of the two longitudinal beams 8.

[0066] Fig. 9 schematically shows a further embodiment in which the longitudinal beam 8 and the cross beam 9 are of different heights. However, the centers of the connecting openings 12 are equidistant from the undersides of the longitudinal beam 8 and the cross beam 9, so that the same support heads 11 can be used.
