Description

Device for connecting stacked

Formwork panels

The invention relates to a device for connecting formwork panels, preferably of the same size, which are stacked on top of one another or the like plates, the webs forming their end face in the edge area or the like and points of attack for fastening elements, preferably have holes for through bolts.

In particular during transport, be it on a vehicle, be it on a crane or the like. Funding means, often whole Stack of formwork panels held together. Otherwise, such a stack would be in relation to the transport movements not stable enough. It is known to tie such stacks together with ribbons. However, this is complex and the bands can only absorb tensile forces, so that it is not guaranteed that such a stack really held together remain.

The object is therefore to create a device of the type mentioned at the outset with which Formwork panels can be connected quickly and yet stably so that they do not fall apart even in the event of strong vibrations or the stack is dangerously deformed.

The solution to this problem is essentially that the device is designed as an angle rail, which in

one end region has an extension of one angle leg relative to the other angle leg and on this Extension has a fastening element and which also preferably in the opposite end region at least an angle leg at least one point of attack for a Fastening element for connecting to the points of attack for fastening elements of the formwork panels or the like. Through this it is possible to attach the fastening element located on the elongated angle leg to a corresponding fastening hole a formwork panel, then the angle around this fastening point against the edge area of the panel stack to pivot and now to fix with the other point of attack. The angle rail then engages the edge area of the panel stack and is fixed in this position, so that especially when using several such Angle rails on the different edges of the stack this stack is well stabilized. By the aforementioned pivoting movement can, in an advantageous and yet to be described manner, also the locking of the in this Area located fastening element take place. In addition, this pivoting movement allows simultaneous alignment the possibly not exactly stacked formwork panels. It is to be regarded as a very special advantage that a substructure of the stack is not necessary because the outer formwork panels are fixed and then the can hold the entire stack together in the vertical direction.

Although FR-PS 22 68 712 discloses a holding structure for stacks of stones that fix them on a pallet should and has four angled rails, which, however, cannot have fasteners to connect with the stones, still manage without a substructure. Rather, the four angle rails even have to be connected with tension elements will. A transfer of this known device to formwork panels in the manner sought here is therefore not possible possible.

130020/0093 / 3

A particularly useful embodiment of the invention can consist in that a with the inside of the extended angle leg in the extension area firmly connected fastening element is provided which the The shape of a bolt or the like with a counter-stop arranged at a distance from the inside of the angle leg. Such a fastener can be easily made through appropriate points of attack or perforations on the edges lead from formwork panels and then pivot, whereby the counter-stop comes into a closed position.

The counter-stop, which is preferably designed as a transverse pin or the like, can be opposite to the orientation of the fastening hole for this bolt stand at an angle with the cross pin and pivot the angle rail around the bolt axis be brought away from the panel stack in accordance with the orientation of the mounting hole. Through this it is achieved that the angle rail in an inclined position relative to the edge profile of the panel stack on a Formwork panel can be attached and inserted with its fastener, after which it is pivoted into the functional position and is thereby secured at the same time. The fixed fastening element is always in the functional position automatically secured against loosening. To remove the angle rail, swivel in the opposite direction, after which a release is possible again.

It is particularly advantageous if the second leg, which is lengthened with respect to the one leg, is connected to the stationary one Fastening element is arranged at the lower end of the angle rail. The fixed fastener can then be attached to the attached to the lower panel of a stack and fixed in a vertical position by swiveling up the angle rail will. In an embodiment yet to be described, in which the angle rail devices for a Crane hooks or the like, the forces are then also special

1 30020/0093

ders favorably initiated via the fixed fastening element on the stack and thereby the bottom panel.

An advantageous embodiment of the invention with a favorable compromise between pivotability of the angle rail and good fixation in the vertical position of this rail can consist in that the counter-stop of the preferably in the lower end area of the angle rail firmly attached fastening bolt or the like at 45 ° from the outer face of the associated Winkelschenkel.3 seen from to the Inside edge is arranged rising. The angle rail then only needs to be attached to the stack of panels to be swiveled out of the vertical to be swiveled with its fastening bolt and its cross pin through the corresponding Perforation of the bottom panel to be able to be passed through. Then it is then adjusted by the appropriate angular amount swiveled up, which also provides sufficient anchoring of the cross pin behind the edges of the perforation the panel results.

In the upper area of the angled rail, a keyhole-like recess can preferably be provided on each of the two angled legs be provided in accordance with the keyhole-like recesses on the end faces of the formwork panels, through which as a fastening element, a bolt with a stop and a counter-stop designed as a transverse pin or the like can be pushed through and rotated to set, after which the transverse pin engages behind the edges of the perforations. Here can the bolt z. B. be inserted from the inside of the panel, so that only its end with the cross pin on the outside the angle rail comes to rest. The handles are then practically protected behind the webs of the Formwork panels and can lie flat on the back of the top formwork panel, so that they can even go through the Gravity are secured in this position and, on the other hand, unwanted loosening is avoided. This is favored if the keyhole-like recesses or the like.

130020 / OQ93 _{/ 5}

Long holes are oriented with their longitudinal orientation transversely to the longitudinal direction of the angle rail and the handles of the bolts Stand at right angles to the cross pins.

The device according to the invention can especially also be used for one Transporting a stack of panels with the help of a crane can be used if on the angle rail in particular on their At the upper end a hitch, preferably an eyelet, preferably protruding above the two angled legs Od. Like. Attached, in particular welded on. The device then not only holds the stack in alignment Position, but it also holds this stack on a crane.

For a clean alignment and stable holding together of the stacked formwork panels, it is useful if on the outside the angle leg close to the edge area each has a bend or the like. Is provided that the edge area of the Brings the angle rail at a distance from the edge area of the formwork panels that are held together, especially both the edge area the formwork panels as well as rolled or folded angle legs is often rounded and there are sometimes also different radii of curvature available. By the aforementioned measure is now achieved that the actual Edges of the parts to be fastened to one another do not come into contact with one another, so that dimensional deviations are immediate in the edge area does not affect the strength of the connection of the free edges of the legs of the angle rail with the Impact formwork stack. It should be mentioned that a particularly stable fixation of the stack results, if at least two, preferably four diagonally opposite angle rails on a stack of formwork panels are appropriate. This then also has the advantage that the angle legs can be relatively short. Will be less than four angle rails are used, a relatively stable bond can still be achieved if the angle legs are used accordingly are long and optionally have several fastening points, in particular at the same height.

Further refinements of the invention are the subject matter of further claims.

The invention and its essential details are given below with reference to the drawing described. It shows:

Fig. 1 is a perspective view of a panel stack with the angle rail according to the invention is held together at all four corners,

on a larger scale
Fig. 2 shows an angle rail according to the invention and

Fig. 3 is a front view of the angle rail in the functional position with a cross section of the attached to it Lanyard.

For connecting formwork panels of the same size stacked on top of one another 1, the webs 2, which form their end faces in their edge region, and points of application for fastening elements, in the exemplary embodiment Holes for push-through bolts, not shown, are for each corner or edge area of the Panel stack provided an angle rail designated as a whole by 3. The angle rail 3 has in one end area, in the exemplary embodiment in the lower end area, an extension 4 of one angle leg 5 relative to the other Angle leg 6. On this change 4 is a fastening element 7 firmly attached. In addition, there is at least one angle leg, in the exemplary embodiment on both Angle legs 5 and 6 each have a point of attack for a fastening element, in the exemplary embodiment keyhole-like 8 perforations for corresponding push-through bolts rait cross pins designed as counterstops, provided, <3ie the corresponding perforations on the webs 2 of the formwork panels 1 correspond. These perforations in the webs 2 of the formwork panels 1 are generally used to attach them to

each other. So you are now being used to be able to be positively connected to the angle rail 3, wherein the same fastening element can be used in an advantageous manner, which is used to connect the formwork panels 1 exists anyway, and is described e.g. in DE-O ^ 21 37 505 is.

The fastener firmly connected to extension A. 7 is arranged on the inside of the elongated angle leg 5 and also has the shape of a bolt, which at a distance from the inside of the angle leg 5 has a counter stop. In the exemplary embodiment, the counter stop is as Cross pin 9 is formed, which fits into similar keyhole-like recesses as in the upper region of the angle rail 3 as recesses 8 and also, as already mentioned, in the webs 2 of the formwork panels 1 are present.

It can be seen in Fig. 2 that this transverse pin 9, which can optionally also be formed in one piece with the bolt 7, is inclined stands, so that the angle rail must first be pivoted out of its vertical position, so that this cross pin 9 with the corresponding extensions of the keyhole-like recesses in the panel edges in accordance comes and can be introduced. In the functional position shown in Fig. 1, the transverse pin 9 is then opposite the Recess pivoted so that it engages behind the edges and is secured. Unintentional loosening in the functional position is therefore excluded without additional manipulation when fixing the angle rail 3 to the lower Formwork panel needs. As already mentioned, the extension A is located with the fastening element 7 in the lower End area of the rail 3. A reverse arrangement would also be possible. However, it is more convenient to use the lower area if the angle rail is inclined to be attached to the stack of formwork panels and then swiveled into a vertical position, after which the additional fastening bolts can be set in the upper area, i.e. at a relatively comfortable height, especially since in the lower stack area the accessibility for a bolt to be inserted from the inside to the outside would be poor.

130020/0093 _{/ 8}

It can be seen that the counter-stop, designed as a transverse pin 9, of the firmly attached fastening bolt 7 below 45 as seen from the outer end face 10 of the associated angle leg 5 to the inner edge 11 of the angle rail is arranged ascending. This makes it possible to the angle rail 3 at an angle of about 45 ° relative to the Set the edge of the panel stack on this and then swivel it up into the functional position, whereby the automatic Securing of the fastening element 7 takes place. After that, in the upper area of the angle rail 3 on the two Angle legs 5 and 6, the fastening bolts through the keyhole-like recesses 8 and the corresponding Recesses on the end faces or the webs 2 of the formwork panels 1 are inserted and also fixed by turning will. The result is an extremely stable stack of formwork panels that can even be used when the vehicle is moving violently cannot be destroyed or impaired during transport.

Due to the geometric relationships, it is useful if the fixed fastening element 7 on the angle rail 3 and the same angle leg 5 associated perforation 8, which is preferably at the opposite end of the Angle rail 3 is arranged, lie exactly one above the other in the functional position and when the distance between them Fastening points corresponds to an integral multiple of the total thickness of a panel 1. Through this arrangement it is ensured that when fixing the fastening element 7 to a hole in a formwork panel, the recess 8 comes in overlap with a corresponding hole of the same, but higher lying panel. The distance these fastening points is one panel thickness less than the total height of the desired panel stack, since each of these fastening elements engages approximately in the middle of the web 2 of a formwork panel. Shall, for example twelve formwork panels 1 stacked on top of one another are held together and connected, corresponds to the distance

130020/0093 ^{/ 9}

ORIGINAL INSPECTED

between the two fastening points on the angle rail 3 eleven times the total thickness of a formwork panel, where applicable there is still a certain tolerance to be taken into account.

It should be mentioned at this point that possibly fewer formwork panels with the angle rails according to the invention 3 can be connected by leaving a gap between the top panel and the next one. the Formwork panels between the lowest and the uppermost formwork panel are then loosely, but due to the stable composite between the respective outer formwork panels 1 by the angle rails 3 do not fall out of this stack. So if, for example, one or two formwork panels less than a complete stack are being transported should, however, the same angle rail 3 can be used.

The key-less recesses or the like elongated holes are in the exemplary embodiment with their longitudinal orientation oriented transversely to the longitudinal direction of the angle rail 3. This means that they overlap with the corresponding perforations on the webs 2 of the formwork panels 1. This allows the connecting bolts belonging to the device to handle may have, which are transverse to the orientation of the angle rail 3 when the stop projections that the cross pin 9 correspond to the fastening element 7, in the orientation of the angle rail 3 and transversely to the greatest extent the mounting holes 8 are oriented. Will the fastening bolts inserted from the inside of the panel stack outwards through the angle rail 3, lie in secured position the handles in such an arrangement parallel to the formwork and can therefore on this rest. They are then additionally secured in this position by gravity and because they are inside the outline of the entire stack and are arranged behind the legs 5 and 6 of the angle rail 3, is an unintentional

1 30020/0083 / io

Solution of this connection is practically impossible.

The great stability of the panel stack according to FIG. 1 has already been pointed out when this is in the above-described Way is fixed in particular by four angle rails 3. The stability is so great that one is special Expedient embodiment of the invention can consist in that on the angle rail 3, in particular at its upper end a towing device that preferably protrudes upwards, preferably an eyelet 12 or d ^ l. attached, in particular can be welded, as is also shown in the exemplary embodiment. At the eyelets 12 can corresponding Tension elements of a crane or the like. Be attached and lift the entire, very compact and stable stack and offset. The unloading or loading of a vehicle that transports such stacks is correspondingly simple, and moving the stack of formwork panels on a construction site. Such a stack of formwork panels can also look good a greater height of an already partially formed or erected building can be brought.

Especially in Fig. 3 it can be seen that on the outside of the angle legs 5 and 6 each have a bend 13 or the like. Deformation, in the exemplary embodiment a corresponding bend, is provided that the edge region 11 of the angle rail 3 at a distance from the edge area 14 of the held together Formwork panels 1 brings. Inaccuracies in the various edge areas 11 and 14 do not lead to that the angle rail 3 with its legs 5 and 6 cannot rest cleanly and firmly against the panel webs 2. Impurities in this area also impair the desired solid support of the legs on the webs 2der This does not mean formwork panels.

In detail it can be seen that the outer edge regions 15 the angle legs 5 and 6 are at right angles to each other and a bend extending in their longitudinal direction

130020/0093 / 11

ORIGINAL INSPECTED

13 have on the outside of the angle leg forms an obtuse angle, and that the inner edge region 11 of the active rail 3 has a smaller angle than 90 ° includes. Ties represents a particularly simple embodiment of the arrangement described above, in which the edge area 11 of the angle rail and the outer Edge area H of the panel stack must be kept at a distance from one another.

The rods 16 of the attachment eye 12, which preferably run parallel to one another, are ar. The derj outer sides of the angle rail 3 are preferably arranged in the area outside the bends 13 and welded in the exemplary embodiment. In the exemplary embodiment, the angle rail 3 consists of rolled material of constant thickness over the entire cross section.

Overall, there is a device with which above all Formwork panels can be held together quickly, easily, safely and stably, so that a substructure in the form of a pallet, Spannbäncer and the like. Can be omitted. Nevertheless, there is the possibility of the entire stack with its connecting device can also be attached to a crane. For the fixation you can! same fasteners as for later connector: the panels themselves can be used. When using four transport brackets 3 with lifting eyes 12, a four-piece sling can easily be used for hanging on a crane.

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