• einen weiteren Schalungsträger.

The invention also relates to a formwork support device, having:

• a formwork girder and
• another formwork girder.

• mehrere Schalungstragvorrichtungen, und
• mehrere Schalungsstützen zur Abstützung der Schalungstragvorrichtungen.

Finally, the invention relates to a ceiling formwork, having:

• several formwork support devices, and
• several formwork supports to support the formwork support devices.

Floor formwork with longitudinal and transverse beams for supporting formwork panels are known in the prior art (cf. e.g WO 2016/116532 A1 ). The longitudinal beams are mounted on the retaining heads of the formwork props. The crossbeams are placed on the longitudinal beams, essentially transversely thereto. Finally, formwork panels are placed on the crossbeams. The longitudinal beams have a predetermined length. Depending on the dimensions of the slab formwork, several longitudinal beams are arranged one behind the other in each row. For this purpose, the consecutive side members are slightly offset laterally, so that the ends of the side members can be arranged so that they overlap. The longitudinal beams are usually supported in the overlapping area with a formwork prop. Disadvantageously, however, the longitudinal beams remain displaceable relative to one another in the longitudinal direction, which can result in instability of the ceiling formwork without additional measures, such as support legs, for example.

In the prior art, floor formwork is also known in which the ends of the longitudinal beams are hooked directly into heads on the formwork supports. From a static point of view, however, there are no significant improvements. In contrast, the object of the present invention is to alleviate or eliminate at least individual disadvantages of the prior art. The invention aims in particular to create a formwork support with which the stability of a floor formwork can be increased and the use of formwork supports and the support legs required for them can be reduced. Carriers or connections for carriers are known from the prior art DE 20 2013 104 108 U1 , FR 744 080 A , JP S61 102714 U , U.S. 2,106,084 A , WO 2015/196264 A1 and WO 01/36761 A1 known.

the U.S. 10,053,875 B1 also discloses formwork supports which can be connected to crossbeams using connecting elements which are located on the end faces of the formwork supports and which are designed in the same way.

Out of EP 1 903 163 A1 a formwork structure is also known in which girders are connected by frontal female and male hooking devices.

This object is achieved by a formwork support having the features of claim 1, a formwork support device having the features of claim 10 and a slab formwork having the features of claim 11. Preferred embodiments are given in the dependent claims.

• die erste Verbindungslasche des weiteren Schalungsträgers ident zur ersten Verbindungslasche des Schalungsträgers ist;
• das erste Kopplungsteil des Schalungsträgers als Einhängeglied und das zweite Kopplungsteil des Schalungsträgers als Aufnahmeglied ausgebildet ist, wobei sich das erste und das zweite Kopplungsteil des Schalungsträgers voneinander unterscheiden; und
• das erste Kopplungsteil des Schalungsträgers bzw. des weiteren Schalungsträgers von oben in das zweite Kopplungsteil des Schalungsträgers bzw. des weiteren Schalungsträgers einhängbar ist.

According to the invention according to claim 1 it is provided that

• the first connecting strap of the further formwork support is identical to the first connecting strap of the formwork support;
• the first coupling part of the formwork support is designed as a hooking member and the second coupling part of the formwork support is designed as a receiving member, the first and the second coupling part of the formwork support being different from one another; and
• the first coupling part of the formwork support or of the further formwork support can be hooked into the second coupling part of the formwork support or of the further formwork support from above.

When used in a slab formwork, two formwork supports according to the invention are coupled to one another via the corresponding coupling parts on the face sides of the formwork supports that meet in such a way that the longitudinal axes of the formwork supports are essentially in line, i.e. collinear, and a longitudinal displacement of the connected formwork supports against one another is blocked. Thus, the formwork supports can be releasably connected to one another at the end faces in order to effect a force transmission along the formwork supports. Advantageously, the stability of the ceiling formwork can be significantly increased in this way. In particular, it is favorable that a continuous beam effect is achieved, which can be taken into account for the necessary load-bearing capacity of the floor props. In this way, the number of formwork props can be reduced. Furthermore, it is not necessary to provide a lateral offset between the successive formwork beams in order to create an overlapping area at the end areas. Another advantage is that it is not necessary to support the connected formwork girders at the longitudinal connection. In a preferred embodiment, therefore, the coupling area between the two formwork supports is not supported by a formwork support. The first connecting strap is mounted on the first end of the formwork girder, i.e. attached to the first end of the formwork girder via a fastening device. Advantageously, the first connecting lug is designed as an adapter, which can in particular also be attached to conventional formwork supports.

For purposes of this disclosure, the location and Directional information such as "horizontal", "vertical", "above", "below" indicates a horizontal state of use of the formwork girder. "Releasable" means that a connection can be made and released again several times, preferably without tools, without significant functional losses.

Preferably, the lower strap and the upper strap each have a width (i.e. horizontal extent) of 50 mm to 100 mm, in particular substantially 80 mm. The web preferably has a height (i.e. vertical extent) between the insides of the top and bottom chords of from 50mm to 200mm, more preferably substantially 120mm. In a preferred embodiment, the total height of the formwork support is essentially 200 mm with a width of the upper and lower chord elements of essentially 80 mm. The upper chord, the lower chord and the web are each preferably formed predominantly from a wood material. Protective caps, in particular made of plastic, can be provided at the ends of the formwork support.

At the second end of the formwork support, a second connecting strap with a second coupling part for the detachable longitudinal connection with a first coupling part of the further formwork support is mounted. Thus, the connecting straps are provided at the two opposite longitudinal ends of the formwork support. The second connecting strap with the second coupling part is set up for a longitudinal connection with the first connecting strap of the further longitudinal member, which is identical to the first connecting strap of the formwork support. The first and second coupling parts differ from each other in order to enable easy connection of the formwork girders. According to the invention, the first coupling part is designed as a hanging member and the second coupling part is designed as a receiving member. The first coupling part is hooked into the second coupling part from above.

The first and the second connecting strap are preferably made of metal, preferably steel or aluminum, or made of a plastic.

According to a preferred embodiment, a bolt is provided as the first coupling part of the formwork support and/or a bolt receptacle is provided as the second coupling part. The bolt receptacle has a cross section that is open at the top, so that the bolt can be inserted into the bolt receptacle from above.

According to a preferred embodiment, the second connecting lug of the formwork support has a retaining element for securing against excavation above the bolt receptacle. The retaining element above, i.e. at a vertical distance from the bolt receiver, prevents the formwork support from being accidentally lifted vertically upwards from the horizontal position of use. During disassembly, the formwork support is swung down, the retaining element not being effective in the swung-down position of the formwork support, in order to enable the formwork support to be removed.

With regard to a structurally simple, reliable design, it is advantageous if a plate part is provided as the retaining element.

In one embodiment variant, the retaining element is movably arranged on the first connecting lug of the formwork support in order to be transferred from an operative position into a dismantling position. In the operative position, the retaining element prevents the formwork support from being able to be lifted vertically upwards from the horizontal position of use. In the dismantling position, the retaining element allows the formwork support to be removed from the horizontal position of use.

In order to facilitate the connection of the formwork support to the further formwork support, in a preferred embodiment the second connecting strap of the formwork support has a guide element which protrudes upwards, in particular obliquely upwards, from the second coupling part, in particular from the bolt receptacle.

In order to dissipate loads when using the formwork girder, it is beneficial if the first and/or second connecting strap of the formwork support has an upper support part resting on the inside of the upper flange and/or a lower support part resting on the inside of the lower flange.

For retrofitting existing formwork supports, the first connecting strap has a fastening leg on opposite long sides of the web. The first and second fastening legs are preferably designed as fastening plates, which are arranged essentially parallel to the web. This enables stable attachment of the first connecting strap to the formwork support. The first and second fastening legs preferably do not protrude laterally beyond the upper and lower chord of the formwork support. The second connecting strap preferably also has a first and a second fastening leg, so that reference can be made to the above explanations.

In order to equip conventional formwork supports with the first connecting strap, it is favorable if the web has at least one through-opening at the first end, through which a fastening element, in particular a screw, of the first connecting strap is guided. A particular advantage of this embodiment is that many formwork supports already have such a through opening (e.g. for attaching a crane suspension or a side protection adapter), which can thus be used for retrofitting the first connecting strap. The screw is preferably arranged substantially perpendicularly to the main plane of the web between the upper chord and the lower chord. It is particularly preferred if two through-openings are provided at a longitudinal distance from one another, each of which accommodates a fastening element, in particular a screw. The second connecting strap can be attached to at least one additional through-opening at the second end of the formwork support via at least one additional attachment element.

When constructing a ceiling formwork, two formwork supports are detachably connected to one another in the embodiment described above. For this purpose, the first connecting strap of the formwork support is brought into engagement with the second connecting strap of the further formwork support, so that the formwork support and the further formwork support are secured against being pulled apart in the longitudinal direction. In the connected state of use, the longitudinal axes of the formwork support and the further formwork support are essentially aligned in the same horizontal plane, ie collinear. When in use, the formwork supports are preferably supported by a plurality of formwork supports.

When assembling the ceiling formwork, for example, the further formwork support can first be arranged in the essentially horizontal position of use, in which the further formwork support is supported by at least one formwork support. The formwork support is then connected to the further formwork support in an intermediate position arranged at an angle to the vertical, then pivoted into the horizontal position of use and supported by a further formwork support. On the formwork girders, the so-called primary girders, which are supported directly on the formwork props, several transverse girders can then be arranged essentially transversely to them. The crossbeams can be designed in accordance with the previously described formwork beams, but a conventional design without first or second connecting straps can also be used. This process is repeated as often as required, depending on the dimensions of the ceiling formwork. Finally, a number of formwork panels are positioned on the crossbeams so that a ceiling formwork is available for concreting a ceiling element.

Telescopic supports are preferably provided as formwork supports, each with a lower support part and an upper support part. Due to the longitudinal connection between the formwork supports, at least individual formwork supports, in particular between the edge areas of the ceiling formwork, can be free of support legs protruding from the lower support part.

1 shows a slab formwork 1 with telescopic formwork supports 2 which, as usual, each have a lower support part 3 in the form of an outer tube and an upper support part 4 in the form of an inner tube that can be displaced therein. The length of the telescopic formwork prop 2 is set using a locking element 5 . A nut is provided for fine adjustment of the length of the formwork support 2 and is screwed onto an external thread of the lower support part 3 . The formwork supports 2 have at the upper ends of the upper support part 4 holding or supporting heads 6, on which formwork supports 7 are supported. Arranged on the upper sides of the formwork supports 7, essentially perpendicular thereto, are transverse supports 8, on which formwork panels 9 are in turn placed. The tops of the formwork panels 9 form the formwork skin on which a ceiling element (or a floor element) is cast from concrete. For the sake of a better overview, 1 not all crossbeams 8 and formwork panels 9 are drawn. In the embodiment shown, the formwork supports 2 each have a plurality of support legs 10 on the lateral edge regions of the ceiling formwork 1 , which are supported on a floor surface 11 . In contrast, the formwork props 2 inside the slab formwork 1 between the lateral edges of the slab formwork 1 are free of such support legs 10, so that the formwork props 2 are only supported on the bottom surface 11 via base plates 12 at the lower ends of the lower support parts 3. This leaves more space between the formwork props 2.

How out Figures 2 to 4 As can be seen, the formwork supports 7 each have an upper chord 13, a lower chord 14 and a web 15 connecting the upper chord 13 to the lower chord 14, so that the formwork supports 7 are I-shaped in cross section (perpendicular to the longitudinal axis). The upper strap 13, the lower Belt 14 and web 15 are each formed predominantly from a wood material in the embodiment shown. Protective caps 16 made of plastic are provided at the ends of the formwork support 7 . A first connecting strap 17 with a first coupling part 18 is also mounted on the first end of the formwork support 7 and a second connecting strap 19 with a second coupling part 20 is mounted on the second end of the formwork support 7 . The first and the second connecting strap 19 are made of metal, preferably steel or aluminum, or made of a plastic.

How out 5 and 6 As can be seen, the formwork supports 7 can be connected to one another in pairs by hooking the first coupling part 18 of one formwork support 7 into the second coupling part 20 of the other formwork support 7 . The first coupling part 18 and the second coupling part 20 are thus set up for a detachable connection to one another. A bolt 21 is provided as the first coupling part 18 , and a bolt receptacle 22 in the form of a depression open at the top is provided as the second coupling part 20 . The second connecting bracket 19 also has a guide element 23 which protrudes obliquely upwards from the second coupling part 20, here the bolt receptacle 20, in order to facilitate the hanging of the bolt 21 into the bolt receptacle 22. At a vertical distance from the bolt receptacle 22, the second connecting strap 19 has a retaining element 24, which covers the bolt receptacle 22, so that the bolt 21 abuts against the retaining element 24 when it is lifted vertically. As a result, the formwork support 7 is secured against excavation. In the embodiment shown, a plate part is provided as the retaining element 24 , which completely covers the bolt receptacle 22 .

How out 5 and 6 further visible, the first connecting strap 17 and the second connecting strap 19 each have an upper support part 25 in contact with the inner side 13a (i.e. with the side facing away from the formwork panel 9) of the upper chord 13 and a lower support part 26 in contact with the inner side 14a (ie with the side facing away from the formwork support 2) of the lower belt 14 of the formwork girder 7.

In this way, favorable load transfer is achieved when the formwork supports 7 are in the connected state.

Like in particular 9 and 10 As can be seen, the first connecting strap 17 and the second connecting strap 19 each have a fastening leg 27 on the opposite longitudinal sides 15a of the web 15 . The fastening legs 27 are pushed onto the web 15 in such a way that the first coupling element 18 is arranged in front of the first end face of the I-shaped longitudinal section of the formwork support 7 and the second coupling element 20 is arranged in front of the second end face of the I-shaped longitudinal section of the formwork support 7. At the first and second end, the web 15 of the formwork support 7 has at least one through-opening 28, here two through-openings 28 at longitudinal distances from one another, which in the installed state are aligned with fastening openings 29 of the first connecting lug 17 and the second connecting lug 19, respectively, in order to align the arrangement of fasteners 30, here screws to allow.

In the Figures 11 to 13 the support of the formwork support 7 on the holding head 6 of the formwork support 7 is shown in detail. In the embodiment shown, the holding head 6 has a first connection element 31 which is set up for a detachable connection to a second connection element 32 at the first end of a crossbar 33 . In the connected state, the crossbar 33 protrudes from the holding head 6 in a horizontal plane essentially perpendicular to the formwork support 7 . A corresponding second connection element 32 is provided at the second end of the crossbar 33, which is hooked into the corresponding first connection element 31 of the holding head 6 of the adjacent formwork support 2 (cf. 1 ). In the embodiment shown, the holding head 6 has a base body 34 made of metal, on which the first connecting element 31 for the crossbar 33 and two hook-shaped gripping elements 35 - which in connection with 17 ff. Are explained in more detail - are formed in one piece.

How out Figures 11 to 16 It can also be seen that the holding head 6 in the embodiment shown has two first connecting elements 31 on opposite long sides of the holding head 6 for the detachable connection with two crossbars 33, so that the formwork prop when in use (cf. 1 ) is supported by the crossbars 33 in both horizontal directions perpendicular to the formwork beams 7. The cross bar 33 has a bar element 33a, here for example with a square cross-section, and brackets 33b at the opposite ends of the bar element 33a. The second connection elements 32, here in the form of retaining bolts, are arranged on the holders 33b, which in the embodiment shown are designed as fork elements.

How out Figures 11 to 16 as can also be seen, two first connection elements 31 are provided on each longitudinal side of the holding head 6 . A receptacle 36 for a retaining bolt 37 of the crossbar 33 is provided as the first connection element 31 of the retaining head 6 .

How out Figures 11 to 16 It can also be seen that the holding head 6 has an upwardly directed guide hook 38 adjacent to the receptacle 36 , ie immediately adjacent to the receptacle 36 of the crossbar 33 . The guide hook 38 projects obliquely upward from a lower end portion of the holding head 6 in order to facilitate the arrangement of the holding bolt 37 during assembly.

the 17 to 20 show the connection of the holding head 6 with a head plate 39 at the upper end of the upper support part 4 of the formwork support 2. The holding head 6 has a horizontal base 40 with an upper side 40a for supporting the formwork girder 7. The two gripping elements 35 protrude from the floor 40 and grip the two opposite side edges of the lower chord 14 of the formwork support 7 when the formwork support 7 is in the assembled state. For this, the gripping elements 35 are designed as L-angle parts. On the underside of the base 40 there are two securing elements 41, here in the form of securing pins, which, when the holding head 6 is installed on the top plate 39, essentially fit precisely into corresponding securing elements 42, here in the form of securing openings, of the Head part 39 of the formwork support 2 are inserted. The securing pins are arranged on opposite longitudinal sides of the floor 40, each one opposite the gripping elements 35. In the embodiment shown, the securing pins are immovably connected to the bottom 40 of the holding head 6 .

Furthermore, a locking element 43 is provided, which can be displaced towards the underside 40b of the floor 40 while keeping a gap free, in order to fasten the holding head 6 to the head part 39 of the formwork support 2 . The locking element 43 is arranged to be displaceable essentially in the longitudinal direction of the holding head 6 . A wedge 44 is provided as the locking element 43, which wedge between a clamping position clamping the head part 39 of the formwork support (cf. Figures 21 to 26 ) and a release position releasing the head part 6 of the formwork prop 2 (cf. Figures 17 to 20 ) is relocatable. The wedge 44 has two wedge parts 45 which are spaced apart from one another in the transverse direction of the holding head 6 and which are connected to one another via a transverse part 46 . In the embodiment shown, a retaining flange 47 is bent downwards from the opposite transverse sides of the base 40 . The retaining flanges 47 each have two retaining openings 48 for slidably receiving the wedge parts 45 of the wedge 44 . The transverse part 46 protrudes laterally beyond the wedge parts 45 so far that the wedge 44 is arranged captively on the holding openings 48 of the holding head 6 .

The holding head 6 also has an anti-twist element 49 for securing the formwork support 7 against twisting during use. The anti-twist element 49 has a spring 50 which can be switched between a locking position that secures the formwork support 7 against twisting (cf. 34 to 37 ) and an assembly or disassembly position releasing the rotation of the formwork support 7. In the embodiment shown, the spring 50 has a spring clip which can be pivoted between the securing position and the assembly or disassembly position. In the embodiment shown, the spring 50 has a bulge 51 for temporary attachment of a tool (not shown) for transferring the spring 50 from the secured position to the disassembled position.

The base 40 of the retaining head 6 has a recess 52, with a retaining section 53 of the spring 50 protruding upwards through the recess 52 in the securing position and being lowered into the recess 52 in the assembly or disassembly position. The holding section 53 has a vertical holding surface 54 which, when in use, is applied to a side surface of the lower chord 14 of the formwork girder 7 . In addition, the holding section 53 has a horizontal pressing surface 55 (cf. 19 ), which facilitates the transfer from the assembly position to the secured position. Below the bottom 40, the spring 50 has an actuating section 56 with the bulge 51 for the tool.
