Description

Device for connecting formwork elements arranged in a plane with outwardly open at their edges Reinforcement profiles

The invention relates to a device for connecting formwork elements arranged in one plane, in particular Formwork panels that open outwards at their edges in the direction parallel to the formwork skin, that is to say with the openings in each case against the corresponding opening on the neighboring panel od The outer leg facing away from the formlining has an edge or a similar bend that is bent over at least in some areas towards the formwork facing and which are releasably held together in the functional position by a removable bracket or the like.

From DE-OS 20 49 245 and DE-OS 27 16 864 it is already known to provide stiffening profiles of the above type on the edges of formwork panels. In the functional position, the edges of the U-legs or the bends should lie against one another or at most have a slight distance in the area of a formwork tie rod penetrating their joint. On the U-crossbars of the stiffening profiles that run at right angles to the formlining, indentations are provided. U-shaped brackets, which encompass the protruding reinforcement profiles on the outside, which can be hinged to the reinforcement profiles and are fixed in the functional position with a wedge or the like, serve as a holder. The articulation can only take place on one of the adjacent profiles, because otherwise simple stripping would be hindered.

In addition, these externally protruding clip-like brackets are especially useful during transport and storage the formwork panels obstructive. The required in DE-OS 27 16 864 for the engagement of a modified clamp element The bead on the U-crossbar of the stiffening profile represents a weakening of this profile, which of all things happens in the when the load is placed in the area of the profiles which is exposed to the greatest pressure.

Another shortcoming of this bracket is that an accurate alignment of the formwork panels in the joint area is not given. In addition, the force applied by the brackets cannot be in the range of, for example, right angles made of stiffening struts, which abut the stiffening profiles and run over the rear of the formwork panel provided that these should be brought up to the stiffening profiles. The brackets can be used next to the appropriate node must be attached, but this leads to a less favorable introduction of force.

The invention is therefore based on the object of a device of the type mentioned at the outset, in which a favorable introduction of force at any point on the stiffening profiles is possible without these weakenings in the form of beads, perforations or the like. Must have. Yet two formwork panels should be able to be firmly clamped together in their joint area with this device and it should be one Further training may be possible, which also allows the formwork panels to be aligned in the joint area.

The solution to this problem is essentially that the holder for engaging behind the bends od. Like. Im Inside of adjacent stiffening profiles is provided that the outer U-legs of the stiffening profiles each have a lower height than the inner legs located in the area of the formwork skin and that the holder insertable through a space between the outer U-legs is.

030040/0396 / 3

The bends on the outer legs thus have the special function of serving for the attachment of the bracket, which can now be arranged at any point due to their arrangement inside the stiffening profiles. Because the bends are provided for the attack of these brackets, is a special deformation on the stiffening profiles for the attack of the bracket no longer necessary, the gap for the introduction of the bracket can either be left at first when the formwork panels are joined together Distance can be made or it is also possible that the thickness of the holder is equal to or smaller than the clear distance is the outer U-leg of two adjacent, abutting stiffening profiles and that the bracket is upright can be inserted between the U-legs and brought into the functional position by rotation about an axis running approximately perpendicular to the formwork facing. Such a design and arrangement is particularly advantageous because the formwork panels can already be in their final position before they come into contact with the The bracket to be subsequently introduced is then firmly connected and pulled together in the joint area.

A particularly important embodiment of the invention can be that the bend or the like on the outer leg of the stiffening profile is directed obliquely from the U-leg to the surface to be concreted and the neighboring profile of the adjacent panel. If a clip-like support is attached at such a slant surface _f corresponding force components are produced parallel to the formwork skin that lead to the desired solid contraction of the shuttering panels in the joint region.

It is useful if the bend or the like runs straight from its bending edge or at least on its inner side Sloping surface is flat. The extension of the holder perpendicular to the formwork facing is expediently the same or smaller as the clear distance between the free edge of the bend and the inner U-leg of the reinforcement profile. The stops

tion can then easily be brought from the outside between the adjacent stiffening profiles and then with their retaining projections pulled back over the inclined bends, which then connects the stiffening profiles.

In particular when the above features and measures are combined, an embodiment of the invention results which is easy to handle, so that it can also be carried out by unskilled workers, in which case it is more advantageous Way, the bracket at any point on the formwork panels, so also in a sufficient number distributed over their height can be.

A further development of the invention of considerable importance, which also includes the alignment of the adjacent formwork panels facilitated, can consist in the fact that the holder engages a region lying approximately in its area between the bends Has clamping element with an abutment supported on the outside of the formwork. On the one hand can as a result, the bracket can be tightened well from the outside, whereby the aforementioned force components are parallel to the formlining come into effect accordingly. In addition, however, the abutment mentioned can serve as an alignment aid.

This is achieved in a simple manner in particular when the abutment on the tensioning element is relative to the tensioning element slidable and pressable against the outside of the panel bracket is formed, which to the plant has the adjacent formwork panels aligned with each other for the simultaneous alignment of the formwork panels.

The clamp effect of the holder can be improved by placing the holder two behind the bends gripping, engaging projections on their inclined surfaces, which in the functional position, d. H. after this Tighten the clamping element, with its end faces even

030040/0396 _{/ 5}

in good time against the inside of the outer U-legs. Through this the result is a particularly firm and stable bond in the area of the holder and the risk of deformation below the influence of a load is reduced "

This effect can be further improved by the fact that the holder is formed by at least one flat iron or the like, which engages behind the bends to form the two Has projections facing away from the formwork facing open slots for the entry of these bends. At least the in each case a bend engaging behind the edge of the slot of the bracket run obliquely with respect to the central axis of the bracket, i-jobei the orientation of this slope in the functional position corresponds to the slope of the bend at least approximately. In the functional position, this results in an over the entire overlap between the edge of the slot and the bend running system, which is in addition to the system on the inside of the outer Schenkels comes and thus leads to a stable situation. Furthermore, the slot can narrow towards its closed end and the edge of the slot located on the outside of the bend can preferably be parallel to the central axis the bracket and / or at right angles to the formwork facing. This allows the bend in the functional position at least at its free edge in the slot on both sides, is preferably clamped.

The alignment effect of the entire device can thereby be improved be that the abutment bracket a the width of adjacent stiffening profiles exceeding or overlapping Has length and that at least at its ends contact surfaces for pressing against the outside of the formwork, in particular has associated stiffening struts on the formwork panel. As a result, this bracket can have its dual function, on the one hand as To serve as an abutment for the inner bracket and, on the other hand, to align the formwork panels in alignment with one another, fulfill even better because, on the one hand, the alignment is simplified by the greater distance between the contact surfaces and

030040/0396 ,,

/ D

on the other hand, larger forces can also be transmitted.

The abutment bracket can also have contact surfaces in the area have the holder, which rest in the functional position on the outer sides of the outer legs of the stiffening profiles. This then becomes the outer leg of the stiffening profile between this additional contact surface and the end face of the corresponding projection of the bracket firmly clamped, so that a total of when connecting the Schaltafein not only creates a frictional connection, but also a positive connection at least in one plane.

The stiffening struts can be butted with the stiffening profiles be connected and preferably have the same height and the contact surfaces of the abutment bracket can in in this case all align with each other. It is advantageously possible in the area of the collision Stiffening struts with the stiffening profiles also to arrange the device according to the invention. A modified embodiment however, it can also consist in the fact that the reinforcement struts are offset in height with respect to the reinforcement profiles the contact surfaces of the abutment bracket offset in the same way and / or subsequently adaptable, preferably are adjustable.

From the above it follows that when a clamp-like combination is used, corresponding insertion slots for the bends having a bracket with a bracket serving as an abutment for a clamping element of this bracket Connecting adjacent formwork panels at any point, in particular also in the area of cross struts, is possible without that on the stiffening profiles perforations, deformations of the webs particularly important for the stiffening perpendicular to Formwork skin or the like is necessary, so that even a composite of several formwork panels connected in this way without dismantling can be implemented.

0300A0 / _0396/7

An expedient one for the simplicity of the overall construction Further development can consist in that the clamping element or the like as a bolt piece and at least with tensile strength the bracket is connected. It becomes expedient in this way usually firmly connected to the holder, possibly welded, so that the above-described insertion the holder in a position at right angles to its functional position and the subsequent rotation into the functional position can be done easily.

For the determination of the abutment when bracing the formwork can be in the longitudinal direction relative to the bolt with inclined surfaces provided clamping parts should be provided »It is possible that a clamping part provided with a on the bolt External thread cooperating, the bracket on the outside or in an opening across the nut is provided. Another embodiment can consist in that a bolt and / or the bracket as a clamping part penetrating or engaging wedge is provided, for this wedge at least in the bolt and possibly an elongated slot is also provided in the bracket and the wedge can simultaneously form an anti-twist device for the bracket. As an anti-twist device between the tensioning element and the bracket, however, the tensioning element can, at least in some areas, also be one of a circular cross-section deviating contour and this area overlapping recess of the bracket a corresponding one Have internal shape.

The above with regard to essential refinements and Developments of the described invention, but which have additional combination features according to subclaims can, allows a further development of its own inventive importance that solves the task with the holder at the same time to be able to make a dimensional adjustment on a formwork by also adding a compensation element between two adjacent Formwork panels can be inserted. This can be achieved in that on the clamping element and / or the holder on the

030040/0398

/ O

the end faces of the projections of the holder opposite side a compensating shell element is provided and the Width of the bracket preferably around the width of this compensation element is enlarged. In this case it is achieved when bracing the bracket that the adjacent formwork panels be tensioned and pulled against the compensating formwork element located between them. The introduction of the holding element then takes place in that this is introduced between these formwork panels with spaced apart until the Bracket rests approximately on the inner legs. In this position, the compensating formwork element now protrudes over the formwork facing out. Now the formwork panels are pulled together until they hit the compensating element, after which the bracket can be withdrawn. It then detects with its slots or the like. In turn, the bends in the stiffening profiles of the two formwork panels and pulls them when braced the device firmly against the compensating element. It is advantageous if the compensating element is in particular a rolled one U-profile is provided, its U-legs on the bracket abut and are preferably fastened there, in particular welded. These U-legs then form at the same time Stops for the otherwise directly abutting end faces of the edges of the formwork panels.

Also other constructions of compensation parts that can attack the holder according to the invention in a different form, are possible and the subject of further claims and are also explained in the following description of the example.

In some cases it can also be useful if the bracket For the passage of several clamping elements or the like. Is provided. This allows either a formwork panel Detect compensation element with a corresponding number of brackets or it is also one opposite the joint of two Formwork panels, staggered arrangement of the bracket is possible, allowing it to clamp in additional stiffening beams, squared timbers or the like. Is suitable.

Q30040 / 0396 _{/ g}

It is particularly useful if the bracket for the Passage of several paralxel tensioning elements and / or for a tensioning element to attack that is offset from its center has an elongated slot oriented in its longitudinal direction »This also makes it possible that here formwork tie rods can also be carried out. If two adjacent formwork panels are offset in height from one another are j so that the stiffening webs or struts of adjacent formwork panels abut on the stiffening profiles are no longer aligned with each other, the device also allows an oblique attack of the bracket, if this is relative can be rotated to the clamping element »

In addition to the connection of formwork panels lying in one plane, the invention also allows an embodiment for formation of formwork corners »This further training option on the one hand sets the invention further apart from the state of the art and also results in an arrangement of its own worthy of protection. Above all, it consists in the fact that an abutment Angle piece is provided and at least on each angle leg on its side facing the surface to be concreted a holder is arranged, which has the design according to the invention and thus between two stiffening profiles can intervene to pull them together in the functional position. The one on the outside corner and on the other Possible designs and configurations on the inside corner are the subject of further claims and are also based on an exemplary embodiment explained in more detail below. It is also important as an additional combination option, how a formwork tie rod can attack in the area of the brackets for the corner connection and how in particular in the inner corner and the correspondingly limited space, the abutment and its bracing option are formed,

It should be mentioned, however, that the device is also particularly suitable for the flat area of formwork panels

030040/0396 ^{/ 1} °

can be developed and designed for additional purposes that the length of the od on the abutment bracket. protruding area of the clamping element carrying the bracket greater than the thickness of a square timber or the like. On the outside of the formwork to be fixed additional part. The abutment bracket can then, under certain circumstances, also come to lie at some distance from the actual formwork panel, whereby this distance is then filled by squared timber or the like. Parts to be determined, which are there with the help of this Brackets are clamped and then also at the same time for the clamping force and the alignment force on the formwork panel care for.

A considerable advantage of the distance between the bends of adjacent stiffening profiles still exists that in this distance noses or projections of consoles, supports or the like. Can be inserted so that these are held in a form-fitting manner in the direction transverse to this slot between adjacent reinforcement profiles.

Especially in an embodiment in which the abutment is to be rotatable relative to the clamping element, it is advantageous to if a handle is provided at the outer end of the clamping element for the holder, with which the clamping element and the bracket attached to it, which is then located inside the adjacent stiffening profiles, are rotatable.

A device designated as a whole by 1, which according to the following Descriptions can have different configurations, each of which is then provided with different reference symbols

030040/0396

/ 13

are, however, as a whole in the following always with the reference number 1 is provided, is used to connect formwork elements arranged in one plane, in particular formwork panels 2 or corner elements still to be described with reference to FIGS. 11 to 13 or also for connecting other elements Formwork parts such as square timbers, consoles and the like with formwork according to FIGS. 17 to 24.

It is part of the device that the formwork panels 2 or the like. At their edges 3 in the direction parallel to the Formwork skin that is open to the outside, that is, with the openings 4 facing the corresponding opening 4 on the neighboring panel 2 Od. The like. Directed U-shaped stiffening profiles 5, the outer legs 7 of which facing away from the formwork skin 6 have a to the formwork skin 6 bent edge, so have a bend 8 and in the functional position by an even closer to Descriptive clip or holder 9 are releasably held together (see. For example. Fig. 1 to 3, Fig. 6 to 9 and 11 to 14).

In the various exemplary embodiments, it can be seen that the stiffening profiles 5 with their inner legs 10 on the side facing away from the concrete of the formlining 6 z. B. are fastened by means of countersunk screws 11 in the formlining 6, wherein at the edge 12 of this inner leg, if necessary, a bevel 14 is connected and formed via a bead 13 is that each overlaps the end face of the formlining panels 6 and preferably flush with that facing the concrete Surface of the formlining 6 completes.

The bracket 9, which is particularly important for the invention, is for engaging behind the bends 8 in the interior of adjacent ones Stiffening profiles 5 provided, which is a particularly simple and useful, but in most Cases occurring embodiment according to FIG. 1 can be implemented particularly easily in that the outer U-legs 7 of the stiffening profiles 5 each have a lower height than the inner ones located in the area of the formwork skin 6

030040/0396 _{/ 14}

Legs 10 have so that the holder 9 through a gap 15 (cf. also FIG. 3, for example) can be inserted between the outer U-legs 7.

2, it can be seen that the thickness of the holder 9 is the same or - as in the exemplary embodiment - smaller than the clear distance between the outer U-legs 7 of two adjacent, abutting stiffening profiles forming the gap 15 5 and that the holder 9 can be inserted upright between the U-legs 7 and rotated by about perpendicular to the formwork skin 6 axis can be brought into the functional position. With such an arrangement - from the according to special application forms and exemplary embodiments, which are still described in the following, but are also deviated from can, the formwork panels 2 can be set up directly abutting, after which the device 1 is attached and is fixed, which leads to the connection of the formwork panels 2.

The bend 8 on the outer leg 7 of the reinforcement profile 5 is starting from the U-leg 7 at an angle against the surface to be concreted and the neighboring profile of the neighboring one Formwork panel 2 directed. The bend 8 is straight or straight from its bending edge 16 or the like. formed flat at least on its inner inclined surface 17. The extension of the holder 9 is perpendicular to the formwork skin 6 equal to or smaller than the clear distance between the free edge 18 of the bend 8 and the inner U-leg 10 of the reinforcement profile 5. In this gap, the holder 9 can be rotated or attached well when pushed in from the side without colliding with the bends 8.

It is essential for a quick and easy assembly that the holder 9 is located approximately in its between the bends 8 Area engaging tensioning element 19 with a supporting on the outside of the formwork, still in detail Has to be described abutment. In relation to this abutment, the holder 9 can be tightened via the tensioning element 19

0300A0 / _0396/15

whereby, via the inclined surfaces 17 of the bends 8, corresponding force components are also parallel to the formwork skin 6 arise which lead to a contraction of the formwork panels with a simultaneous alignment of the formwork skins 6. For this purpose, the holder 9 has two protrusions that reach behind the bends 8 and engage their inclined surfaces 17 20, which are in the functional position, d. H. after tightening the clamping element 19, with their end faces 21 at the same time the inside of the outer U-legs 7 are in contact. This also causes the alignment effect already mentioned, at least in part. In addition, this results in a firm and stable seat with simultaneous support for the outer legs 7 and the bends 8, which in this way can better transfer the various forces.

In this case, it is advantageously provided that the holder 9 has open slots 22 facing away from the formwork skin 6 for the formation of the two projections 20 engaging behind the bends 8 for the entry of these bends 8. In addition to the two projections 20, there are therefore these slots 22, each of which are delimited by an inner projection 23 or the like, on which the clamping element 19 can engage centrally. If necessary, the tensioning element could also emerge directly in one piece from this inner projection 23 or be formed by it, which would be a further possible embodiment of the invention.

An improvement in the force components parallel to the formwork skin 6 can be achieved in that at least the one in each case Bend 8 engaging behind the edge of the slot 22 of the holder 9 runs obliquely with respect to the central axis of the holder 9, the orientation of this incline in the functional position corresponds at least approximately to the incline of the bend 8. Already during the contraction, but also in the functional position, there is then an areal contact between Bend 8 and the outer edge of the slot 22. The surface pressure is correspondingly low and correspondingly close

Q30040 / 039S _{/ 16}

the whole arrangement also comes with a form fit. In the working examples it is also provided that the slot 22 narrows towards its closed end and that the the outside of the bend 8 located edge of the slot 22 preferably parallel to the central axis of the holder 9 and so that it runs at right angles to the formwork skin 6. This makes the slot wider at its free end, so that "finding" of the edge of the bend 8 is facilitated when the holder is attached after it has been rotated into the functional position.

The bend 8 is in the functional position, for. B. according to FIG. 1 at its free edge in the slot 22 and detected on both sides pinched, which avoids the risk of deformation at higher loads and also ensures good power transmission be made possible.

The abutment already mentioned, essential as a further development of the invention, can be used in a particularly favorable and advantageous one Embodiment, which is also shown in the drawings, on the clamping element 19 as relative to this Clamping element 19 slidable and against the outside of the formwork panel 2 or the like. Bracket 24 may be formed, which to rest on the adjacent formwork panels 2 aligned contact surfaces 25 for simultaneous alignment the formwork 2 has. Although the abutment could in terms of its extent to about the total width of the adjacent stiffening profiles 5 be limited. For the aforementioned, advantageous alignment of adjacent Formwork panels, however, it is expedient if the bracket 24, as provided in the exemplary embodiments, is one wider than the other Stiffening profiles 5 exceeding or overlapping length and if at least at its ends Contact surfaces 25 for pressing against the outside of the formwork, in particular stiffening struts belonging to the formwork panel 26 are provided. It is namely an essential advantage of the invention that the holder 9 is also in one area the formwork panels can be installed where such

030040/0396 _{/ 17}

stiffening struts 26 butt at right angles against the stiffening profiles located on the edge, because the holder 9 engages just inside the stiffening profiles 5. In combination with the one used as an abutment, but via the stiffening profiles 5 extending bracket 24, this results in a particularly good combination with the requirement that the formwork panels at the same time also to align with their fixation to each other. This is improved when the abutment bracket 24, such as also provided in the exemplary embodiments, has additional contact surfaces 27 in the region of the holder 9, which rest on the outer sides of the outer legs 7 of the reinforcement profiles 5 in the functional position. This is especially good and can be clearly seen in FIG. 1.

Like other exemplary embodiments, FIG. 1 also clearly shows how the stiffening struts 26 are butted with the stiffening profiles 5 can be connected, this connection expediently being carried out by welding. Appropriately have they have the same height so that the contact surfaces 25 and the abutment bracket 24 can all be aligned with one another.

Of course, however, it would also be possible for the stiffening struts 26 are offset in height with respect to the stiffening profiles 5 on their outer sides, in which case the Contact surfaces 25 and 27 of the abutment bracket 24 would have to be offset from one another in the same way. If necessary, could this contact surfaces, in particular then the outer contact surfaces 25, also to such an offset z. B. by Documents or adjustment options can be adjusted.

In Fig. 1 it can also be seen that between the inner contact surfaces 27 and the outer contact surfaces 25 of the abutment bracket 24 form a distance from the formwork Recess 28 can be provided. This ensures that the bracket, which is also used for alignment, really does with its outer contact surfaces 25 comes into play and not in an area closer to the stiffening profiles

030040/0396

on an irregularity of a stiffening strut 26 or the like. comes to the plant, whereby the alignment could be endangered.

In Fig. 2 it can be seen that at least the outer contact surfaces 25 of the abutment bracket 2k can have a greater width than the bracket 24 itself and possibly even than the stiffening struts 26, so that the surface pressure is well distributed and in an application to be described in which Squared timbers or the like are to be clamped between the bracket 2k and the formwork, a correspondingly good distribution of the pressure forces is achieved. Furthermore, this also results in the possibility of slightly offsetting the bracket with respect to the struts or, with neighboring panels offset in height and accordingly slightly twisted bracket 2k (see Bracket 9 and the simultaneously applied forces for aligning the formwork panels can be made sufficiently large even in such applications.

It can be seen, for example, in Fig. 2 that the holder 9 od from at least one flat iron Thickness is less than the distance between the bends 8 in the case of reinforcing profiles 5 lying together. Such a flat iron can be easily manufactured and also easily provided with the slots 22. In addition, this arrangement allows the already mentioned introduction of the bracket in an upright position, i.e. at right angles to the later one Functional position is.

The already mentioned clamping element 19 can be designed in various ways. An expedient embodiment, which is realized, for example, in FIGS. 1, k and 5, consists in that the clamping element is designed as a bolt piece and is at least firmly connected to the holder 9 in a tensile manner, in the exemplary embodiment it is firmly connected at all. For the determination of the contradiction

0300A0 / 0396/19

bearing when bracing the formwork, clamping parts provided with inclined surfaces can now be provided relative to the bolt piece 29 be. In Fig. 1 and 5 is a clamping part with an external thread 30 provided on the bolt 29, the bracket 24 on its outside - or, in an embodiment not shown, overlapping in an opening Mother planned. This allows a dosed and yet strong development of power.

FIGS k and 8 show a clamping member comprises a bolt 29 and in Fig, H at the same time the bracket 24 passing through or in accordance with Fig. 8 the clip engages behind wedge 32, which for this wedge 32 in the bolt 29 and in the embodiment of Fig. 4 a long slot 33 is also provided in the bracket 24 and the wedge 32 can simultaneously form an anti-twist device for the bracket 24 with respect to the bolt 29. The wedge and wedge surfaces are arranged in such a way that the hammering in of the wedge leads to a displacement of the holder 9 against the bracket 24.

Fig. 5 shows another possibility of rotation, which consists of _f that 24 ·, the clamping element 19 at least partially deviates from a circular cross-sectional contour, and this area 34 across recess of the bracket 24 have a corresponding inner shape between the clamping member 19 and bracket. A rotation on the bracket 24 also leads to a rotation of the holder 9 in this case.

In other exemplary embodiments, it is provided that the bolt 29 engaging on the holder 9 is circular as a whole Has cross-section, so that without an anti-rotation device which penetrates the two parts or otherwise acts on them a relative rotation between bracket and bracket is possible. Especially in this case it can be useful if a handle 35 is provided in particular at the outer end of the clamping element 19 or the bolt 29 for the holder 9, with which the clamping element and the holding

030040/0396 _{/ 20}

tion 9 are rotatable. This facilitates on the one hand any application of the bracket to the outside of the formwork or also on the outside of the parts to be pressed against the formwork, while inside the parts to be connected to one another Reinforcement profiles 5 the bracket can still be easily rotated into the correct position. Such a handle 35 is indicated in Fig. 11, which also serves to describe a possible corner connection. You can still see that in this case a handle 35 slidably penetrating the clamping element 19 in a perforation is provided, which is in the Embodiment has the perforation in the clamping element 19 overlapping stops 36 at both ends. Through this this handle 35 can always return to a comfortable starting position after half a turn in a manner known per se be moved.

It should be mentioned that instead of such the contour of the clamping element outstanding handle at the free end of the clamping element 19 also a deformation od. The like. For the attack of a tool could be provided for the rotation to be performed.

To Fig. 5 it should be added that there is attached to the bracket 9 Starting area 34 of the clamping bolt 29 is polygonal, preferably is square and that on the polygon in particular an outwardly leading threaded area for a clamping nut is provided. A metric thread is indicated in FIG. 5, while it is provided in FIG. 1 that the tensioning thread 30 corresponds to that of a formwork tie rod, so that a corresponding nut is also used as with formwork tie rods finds what relieves storage.

In some cases, adjacent panels cannot be connected directly to each other, but rather it Corresponding compensating formwork elements are necessary to compensate for intermediate dimensions. The present invention now provides by a design of particular importance the possibility of such in turn differently designed, in the following

030040/0396 -

The compensating elements described in more detail with the aid of examples together with the bracket between such adjacent ones To fix formwork panels. It is possible that on the clamping element 19 and / or the holder 9 on the end faces 21 of the projections 20 of the holder 9 opposite side, a compensating shell element 37, 38 or 39 is provided and the width of the bracket 9 or the bracket area is preferably increased by the width of this compensating element is.

In FIG. 6, an exemplary embodiment is shown in which the compensating element 37 is a particularly rolled one U-profile is provided, the U-legs 40 on the um.die Width of the U-transverse web 41 widened holder 9 rest and fixed there in the exemplary embodiment, namely welded. The arrangement is chosen so that the outside 42 of the U-transverse web 41 of the compensating element 37 in the functional position with the outside of the formwork skin 6 of the adjacent formwork panels 2 is aligned. For the assembly of this device 1 with the compensating element 37 attached to it, the entire device is first Moved transversely to the formwork skin 6 in the longitudinal direction of the clamping element 19, the bracket 24 still removed or released is, after which the two formwork panels are brought together until they are directly on the bracket against the U-legs 40 bump. As a result, the slots 22 of the holder 9 and the bends 8 of the stiffening profiles 5 also come into contact with one another suitable position. If the device 1 is now brought into the functional position, d. H. the holder 9 withdrawn, the compensating element 37 is thus also withdrawn again at the same time and aligned with the formwork skins 6 brought. There is then a connection corresponding to the embodiment of FIG. 1, in which only between the edges of the formwork panels are at a greater distance, which is fixed by the device 1 firmly connected Compensating element 37 is bridged. The entire connection is achieved when the clamping nut is tightened sufficiently 31 so stable that such a combination of formwork panels

030040/0396

without dismantling similar to a composite according to FIG. B. could be implemented with a crane.

In a modified embodiment according to FIG. 7 it is provided that in the functional position inside the Stiffening profiles 5 lying area of the tensioning element, a transverse spar A3 is provided, on each of which a mounting part AA is mounted displaceably parallel to the formwork skin 6, and that at the end of the tensioning element 19 a the formwork skin 6 of the adjacent formwork panels 2 overlapping compensation element 38, for example a sheet metal, is arranged. With a device 1 configured in this way, formwork panels that are adjacent to one another can be of different distances from one another connected and aligned with each other. Due to the tensile force of the clamping element when tightening, it is A corresponding clamping force is transmitted to the outer legs 7 of the stiffening profiles 5 via the transverse beam A3 and the mounting parts AA, while the connecting bracket 2A transfers them Legs clamped from the outside, so that a total of a frictional connection is formed in which in an advantageous manner the compensation board 38 is not or not very heavily loaded.

In the exemplary embodiment it is provided that the transverse spar A3 has a polygonal, in particular square, cross-section and that the mounting parts AA have a sleeve A5 running parallel to the formwork skin 6 or the like The inner contour corresponds to the outer contour of the cross member A3 and on the one hand the lateral displacement of the mounting parts AA and, on the other hand, enables the transverse force to be transmitted from the spar A3 to the mounting parts AA.

It can be seen both in the examples described above according to FIGS. 6 and 7 and in the examples yet to be described according to Figures 8 and 9> that especially with additional Arrangement of a compensation part 37, 38 or 39, the contact surface 25 of the abutment bracket 2A over its entire Length or that the contact surfaces 25 and 27

030040/0396 _{/ 23}

-y £ T-

merge into one another, so a recess 28 is missing. This is particularly the case with an anti-ending according to FIG. 7, but also 8 and 9 This is an advantage where it should be possible to bridge distances of different widths equally well.

According to FIGS. 8 to 10, it is possible that the bracket 24 is provided for the passage of several tensioning elements 19 or the like can be. A particularly useful embodiment in this regard, which can be seen primarily on the basis of FIG. 10, is dabsi that the bracket 24 od for the passage of several parallel clamping elements 19. Like. And / or for one Attack of a single tensioning element 19 offset from its center has an elongated slot oriented in its longitudinal direction 46 aufx-jeist.

This embodiment makes it possible, in an arrangement according to FIG. 1, to have one end of the bracket opposite the other of the clamping element starting to stand to the side for a much longer time, e.g. when fixing additional parts in this area or in the case of unfavorable counter-contact surfaces, this can be advantageous.

Primarily, however, this arrangement is again used to fix an equalizing panel 39. In both cases, the FIGS. 8 and 9, the bracket 24 has at least two clamping elements 19 penetrating it, each with a holder 9 Slots 22 of the two brackets 9 facing away from one another now each take a bend 8 of a stiffening profile 5 of a formwork panel on the side of the space to be compensated on and between the formwork panels 2 is the one already mentioned, Compensating panel 39 aligned with the formwork panels 2 is inserted. According to FIG. 8, this compensation panel 39 can be attached to the facing sides of the brackets 9 be attached by means of corresponding stiffening profiles 5, so that practically two immediately adjacent connection points similar to that of FIG. 1 result from a common bracket 24 are bridged. In Fig. 9 it is provided that the compensation panel 39 by means of its own clamping element 47 on the counter

0300A0 / 0396

bearing bracket 24 is fixed. This clamping element 47 consists from a bolt part 48 on which a nut 49 or optionally a wedge can also attack while one or two angle pieces 50 are attached to the formwork panel which the bolt part 48 is fixed, in particular welded on. In this case, too, the bracket 24 is as in the case of those already described above Examples relative to the holder 9 rotatable and optionally fixable, so that optionally with a oblique arrangement of the bracket also the distance of a vertical projection of the brackets to adapt to different wide compensation panels is adjustable. It is true that this distance is also due to a shift in the elongated slot 46 adjustable, but would have the pivoting of the bracket to reduce the distance between the adjacent formwork panels The advantage that the clamping elements are each held in a form-fitting manner by the ends of the elongated slots at least towards one side can be, while with a relative displacement in the interior of the elongated slot then only frictional connection is available.

The device according to the invention is also suitable in an advantageous manner with appropriate adaptation to the particular purpose to form a formwork corner, as shown in particular in FIGS. 11 to 14 and 16. In this case is the embodiment of the invention, which in turn has its own inventive significance, essentially in that as Abutment an angle piece 51 for the outer corner and an angle piece 52 for the inner corner is provided and on each angle leg on the side facing the surface to be concreted at least one holder 9 is arranged. In the case of the The embodiment shown in the drawing are the legs of the elbows 51 and 52 under a predetermined, in the embodiment Right angle, rigidly and integrally connected. However, it would also be possible for the legs of the angle pieces 51 and 52 via flexible connections, hinges or the like. Their angle to one another can be adjusted.

For the construction of the corner formwork according to the invention, it is

030040/0398 _{/ 25}

_ 39-

expedient if in the joint area shown again separately and more clearly in FIG. 12, the angle to one another standing formwork panels 2 of an outside corner, the corner stiffening profiles provided for the attack on the brackets 9 adjacent to the corner 53 are supported, which extend in one piece or in continuation over the entire height of the formwork and are connected to one another, preferably welded, on their side facing away from the formwork skin 6. One recognizes in Fig. 11 that this corner stiffening profile 53 of the outer corner in cross section form approximately the shape of a Y, the outer free edges 54 each having the outer U-legs 7 of the stiffening profiles 5 corresponding legs 55 with bends 8 and these legs 55 are at the angle of the corner to one another, are distributed over the height of the corner stiffening profiles 53 between the webs 56 of the corner stiffening profiles 53 arranged at right angles to the outer legs 55 to their Stiffening and connection gusset plates 57 are arranged, welded in in the exemplary embodiment. The outer legs 55 of the Corner reinforcement profiles 53 are aligned with the outer legs 7 of the adjacent formwork panels 2. This results in a corner connection, which has the advantage that the formation of the profiles to be connected also in the immediate corner area corresponds to that are to be connected in the flat area of a panel, so that in turn brackets 9 with their advantages can be used.

It can be seen in Fig. 11 that the angle legs of the angle piece 51 of the outer corner are connected via an inclined area 58 located in the edge area, which is a fold of the corner forms. In addition, this results in better power transmission in the immediate corner area. For a right angle Outside corner, as shown in the embodiment, are the Y-legs 55 of the corner stiffening profiles 53 and the legs of the angle pieces 51 at right angles to each other and the intended connection 58 of the angle legs closes compared to these angle legs each an angle of 135 °

29120Q5

In particular in Fig. 12 it can be seen that the corner stiffening profiles 53 in the joint area in each case approximately at the level of the inner legs 10 lying on the outside of the formwork skin 6 the reinforcing profiles 5 attacking there are bent over and the inner ends of these bends 59 on the end faces of the Formwork panels 2 standing at an angle to one another preferably meet at right angles and in particular welded there are. The bends 59 of the Y-legs thus form an angular profile in this area, which is in the corner area formed by the front edges of the formwork skins 6 of the formwork panels 2 can be inserted. In Fig. 12 is in a fugue, which does not correspond to reality, is indicated in order to clarify the arrangement.

On the inside corner designated as a whole by 60, there are also reinforcement profiles corresponding to the reinforcement profiles 5 of the formwork panels 2 61 connected, at whose ends facing the formwork the formwork skin 62 is connected to the inner corner 60, is welded in the embodiment. This arrangement can also be seen above all in FIG. 11. Between the knuckles 63 of the an angle-forming formwork skin 62 of the inner corner 60 and preferably the stiffening profiles 61 connected to it are distributed over the height of the formwork gusset plates 64 or the like, stiffeners inserted, in particular welded in, the a right-angled corner according to the embodiment have an approximately square shape.

On the angle piece 52 belonging to the inner corner 60, the passage 65 for the clamping element 19 of the holder 9 of the one angle leg offset in height with respect to the corresponding passage 65 on the other angle leg, which can be seen above all in FIG. In addition, on the angle piece 51 of the inside corner 60 there is an attack for a formwork tie rod 66 is provided, which is offset in height with respect to the passages 65 for the brackets 9. Included the points of application for the formwork tie rods 66 on the angle piece 52 of the inner corner 60 in both legs

030040/0396

because they are on the same level. The points of attack of the formwork tie rods 66 are in the exemplary embodiment in the middle between the vertically offset passages 65 arranged for the clamping elements 19 of the brackets 9, so that overall the most symmetrical power transmission possible results.

In the exemplary embodiment, the formwork tie rods are used as an attack 66 on the sides facing away from the formwork of the angle piece 52 acting nuts 67 or the like. Threaded parts are provided, the internal thread of which corresponds to the external thread of the formwork tie rods 66. The mother 67 or the like. On the Angle piece 52 fastened in a rotationally fixed manner, in particular welded on, which is indicated in FIG. 12 in the area of the inner corner.

In a modified embodiment, which is indicated in FIG is, however, the angle piece 52 in the area of the formwork tie rod 66 can have an open-edged elongated slot 68 one corresponding approximately to the diameter of the formwork tie rod 66 Width for a lateral insertion of the formwork tie rod provided with nut 67 or the like stop from the Have side. In addition to the assembly aid provided by this, dimensional inaccuracies can also be compensated for.

Above all in FIGS. 13 and 14 it can also be seen that the holder 9 has a threaded sleeve in the area of the inner corner 60 69 or the like, preferably in turn a welded-on nut, in which a threaded rod 70 as a tensioning element engages from the outside, which is rotatably, but fixedly mounted in the longitudinal direction. If this threaded rod 70 is rotated, the holder 9 can thus be adjusted in the axial direction. On the side of the angled leg facing away from the formlining 6 of the angle piece 52 provided on the inner corner 60 are now in the exemplary embodiment with the angle piece 52 penetrating threaded rod 70 rotatably connected handles 71 or. Like. Parts, for example, also for the attack of a tool provided, which in the exemplary embodiment has a circumferential groove

030040/0396 _{/ 28}

72 have in which at least one with the elbow Fixedly connected projection 73 or the like. Nose engages. As a result, these handles 71 or the like can be rotated, but in axial direction set. To clamp the holder 9, these handles 71 can now be turned, which in turn the slots 22 of the brackets 9 cooperate with the corresponding bends in the desired manner and the Inside corner 60 and the adjoining panel with one another brace.

According to FIG. 13, it is provided in this exemplary embodiment that the nut penetrated by the rotatable threaded rod 70 or threaded sleeve 69, two corresponding flat irons with mounting slots 22 forming the mounting 9 Od. The like. Are attached and the threaded rod 70 symmetrically between these two flat bars forming the bracket 9 attacks. The bracket 9 is secured against twisting in the area of the corner connection so that the threaded rod cannot turn does not lead to assembly difficulties. To secure the holder 9 against rotation, at least one can their protruding, engaging in a recess of an adjacent profile pin 74 or. Like projection provided be. In order not to have to have special formwork panels intended for the corner area, it is useful if the locking pin 74 in the one belonging to the inner corner 60 Corner reinforcement profile 61 and there in particular in a slot oriented perpendicular to the surface to be concreted intervenes. It then allows the axial displacement of the holder 9, but not the rotation.

An additional or different possibility is that as a rotation lock on the side facing the holder 9 In particular, of the inner corner reinforcement profile 61, a projection 75 or the like is provided, which protrudes into the space between the two the nut 69 or the like. Threaded sleeve between them receiving parts forming the holder 9, in particular intervenes with a little play. This causes a weakening

030040/0398 _{/ 2g}

one of the stiffening profiles avoided by a slot and also the double arrangement of the bracket 9 even better exploited.

For problem-free passage of the formwork tie rods 66, be it in the area of a corner connection or between two formwork, the expedient embodiment shown in Figures 15 and 16 can be provided, the therein consists that the stiffening profile 5, 53 and / or 61 to form a passage for a formwork tie rod 66 with its profile strips or bevels 14 resting on the end faces of the formwork panels 2 in the direction of orientation of the formwork tie rod 66 lines recess 76 or indentation running through this end face. The depth of this Recess or indentation 76 can expediently correspond to the smallest cross-sectional length, in particular the smallest diameter of the formwork tie rod 66 and this can fit into the recess 76 at least without a lateral protrusion. This makes it possible that at the subsequent Counter switchboard no such recess is necessary what a stepless height offset of the abutting formwork panels or other formwork parts.

In particular for the additional application options that have yet to be described According to Figures 21 to 24, it is advantageous if the length of the abutment bracket 24 or also the angle pieces 51 or 52 protruding area of the clamping element carrying the holder 9 is greater than the thickness of a square timber or the like is an additional part to be fixed on the outside of the formwork. As mentioned elsewhere, This makes it possible to use the connecting bracket or the other abutment part or an additional one the clamping nut or the like stop part to be held on the clamping element and thus attachments, scaffolding parts, To fix consoles or the like on the formwork according to the invention.

/ 30 Q30040 / 0396

In Fig. 17 it is indicated how with the device according to the invention even two adjacent formwork panels offset from one another in height can be connected without any problems that it is necessary to insert intermediate pieces or special perforations, long slots or the like on the edge reinforcement profiles 5 to be provided.

Fig. 18 shows, in addition to the connection of adjacent formwork panels, As with a connecting bracket 24 according to FIGS. 8 to 10, a formwork can also be increased, wherein the holder is arranged eccentrically relative to the center of the bracket, because the connecting bracket with its longer Area to extend to the first stiffening strut 26 running parallel to the edge to be bridged.

Another possibility of changing the height of the formwork panels corresponding to FIG. 3 is shown in FIG. 19, where the formwork panel is around Is arranged rotated 90 ° and is provided with an additional part fixed by the device according to the invention.

FIG. 20 shows a variant of FIG. 19, namely the stiffening struts of the formwork panels to be connected are offset from one another, but this is caused by a twisted and thus inclined connecting or abutment bracket 24 can be managed.

In FIG. 21, a console 77 that can be walked on is attached to a formwork panel 2, the device 1 according to the invention being used for this purpose is to clamp a corresponding console part 78 in the manner already mentioned with the aid of the bracket 24 and to fix.

22 shows the connection of a stiffening bracket 79 exactly in the joint area of two adjacent formwork panels. Here is the The detail marked by the circle B is shown more clearly in FIG. 23 and it can be seen how with the aid of the device 1 a bracket part 80 against the formwork and in particular

030040/0396 _{/ 31}

the Ästeifungsprofile 5 is pressed, this console part 80 advantageously has projections or lugs 81 which protrude into the space between the bends 8 of the adjacent Reinforcing profiles 5 can intervene, thereby securing these bracket parts 80 against twisting is achieved.

Finally, FIG. 2h shows how the abutment bracket 24 can be used to fix two squared timbers 82 or also to attach additional boards 83 or the like to the outside of a formwork panel 2. In this case, the connecting bracket is supported on the outside of the additional part to be fixed and transmits its clamping forces via this part and the reinforcement profile to the formwork, while the bracket 9 is simultaneously fixed via the clamping element and thus the connection of adjacent formwork panels is established.

Further advantageous application possibilities are opened up by the device according to the invention, whereby in an advantageous manner weakening of the stiffening profiles by corresponding deformations or even holes, slots or the like can be avoided and nevertheless a favorable introduction of force at any point on the formwork panels, especially in the particularly favorable one the zone of impingement may be made of additional bracing struts to the shuttering panels to align with each other to connect and in the longitudinal direction.

For the stability and rigidity of the formwork panels in particular in its edge area it is advantageous that the reinforcement profiles 5, 53 and 61 forming webs and in particular the web standing perpendicular to the back of the formlining 6

5 a are straight in cross section. Nevertheless, the inventive Attack device 1 on the stiffening profiles.

030040/0396

In Fig. 11 you can also see that the on the clamping element 19 or bolt piece 29 or the like. located one-armed or displaceable handle 35 in the same direction as the largest cross-section running parallel to the formwork skin 6 the bracket 9 is oriented. The same could apply to the wedge 32 which penetrates the bolt piece 29.

The wedge 32 could be connected to the device 1 in such a way that it cannot be lost and is preferably also effectively connected as a handle be. In such a case, a handle 35 could then be avoided. It is then useful if the Wedge 32 has, at least at its thin end, a stop or the like, which has the slot through which wedge 32 passes 33 protrudes on at least one side. Such a stop then practically corresponds to the stops 36 on the Handle 35 and also makes the wedge captive in a desired manner, so that this then has the double function of a Handle and the clamping wedge can exercise.

The mentioned orientation of either the wedge 32 or the handle 35, as shown for the handle 35 in FIG is, leads to the fact that when parallel to the gap 15 between two stiffening profiles 5, so in particular at Edgewise-oriented bracket 9 of the wedge 32 or this handle are oriented in the same position, so in all Usually vertical. As a result, the force of gravity acts on these parts and ensures, especially when operated with one hand a stabilization of this position. It is useful if the wedge 32 then with its strong end downwards hangs. A correspondingly greater force of gravity or weight then acts on the device and thus stabilizes it this position. In addition, with such an arrangement, the wedge or handle can also indicate from the outside whether and how the holder 9 is oriented, which according to the invention is located inside the stiffening profiles 5, that is often not

030040/0396

or is not clearly visible. If the holder is later braced in its functional position, this is an exploitation
Gravity is no longer possible, so that the handle or wedge can then stand horizontally. For a device 1 in which the bracket 24 is to stand vertically in the functional position, a solution could also be provided in which the handle is rotated by 90 ° relative to the holder, so that the force of gravity in the same way in such an embodiment could be exploited. However, since such an arrangement of the bracket 24 will be relatively rare,
such a special additional embodiment will as a rule be dispensed with.

All features and construction details shown in the description, the claims and the drawing can be used as well individually as well as in any combination with one another are of essential importance.
