Description

FIELD OF THE INVENTION

The The invention relates to a formwork device with the features of The preamble of claim 1. Accordingly, a shuttering device for Concreting of cornices, sometimes called caps, on elongated Structures, in particular at bridge structures, the at least one have freely projecting edge. Such a shuttering device, which also on a vertical wall, z. B. a bridge abutment or a support wall / slot wall can be mounted first of formwork beams, in particular perpendicular to the front of the edge of the building and essentially parallel to each other, below the edge of the building and laterally dangling are arranged by this. It means "in particular right angle "a preferred direction of the formwork beams. Basically, not even right angles to the Building edge possible. Likewise, "essentially parallel to each other "that a parallel arrangement or, slightly curved in the case of curved building edges intended arrangement of formwork supports the usual Represent normal case, but not limited to the invention is. The formwork beams carry a cornice formwork. The latter can provided separately or integral part of the formwork device be. The formwork beams can be the height to be adjustable, d. H. liftable and / or tiltable and corresponding Lowerable to quickly adapt to the desired cornice cross section to enable. For this purpose, a lifting device can be used. Additionally or alternatively, it is also possible the formwork by supplements of z. As wood or other distance-forming Building materials individually aligned. A mechanical adjustability the cornice formwork by "lifting devices" in But the most general sense is because of the repetition of the concreting process along the elongated structure in always the same cross-sectional shapes cheaper for putting in and taking off.

The Formwork device further comprises a cornice formwork car Part of the formwork beams are. Accordingly, the Formwork beams indirectly or directly to the cornice formwork car summarized, such. B. by running along the structure Booms. The cornice shuttering car is fastened by means of attachable to the building or attach guides and usually parallel to Movable edge of the building and lockable in the individual concreting position. The cornice formwork wears, z. B. at the inner ends the formwork support, on its building end Support wheels for moving the corn shuttering cart along the Bauswerksrandes. For this purpose, guide rails serve, on or in which the support wheels roll off. Preferably, the support wheels roll on the building base or at another extending in the longitudinal direction Building edge off. These support wheels can through displaceable supports in the concreting position relieved be.

TECHNOLOGICAL BACKGROUND

Generic formwork devices are from the DE 91 07 201 U1 known. The cornice shutter carriage proposed there is in its basic design in two parts and consists of a formwork beams and the cornice formwork and on the other hand, located below the formwork beams support beams. The support beams are by means of fixedly arranged chassis hanging on the fixedly connected to the building guide rail movable, to support the weight load of the cantilever formwork and formwork during the process supporting wheels at the inner end of the lower support beams are supported from below or laterally to the building. The support wheels are relieved for concreting by extendable supports and the formwork beams are together with the formwork by lifting devices in total with respect to the underlying support beams can be raised and lowered. A fixed to the structure to be anchored guide rail section is about twice as long as the cornice formwork carriage. The guide rail sections can be dismantled in the direction of travel at the rear end of the trolley car and offset to its front end. This is done manually and requires a high accuracy in the alignment of the rail. For this purpose, inter alia, wedge-shaped mounting plates are provided which compensate for the usual tendency of cornice bottoms, so that a rigid and perfectly aligned horizontal guideway are achieved for the chassis of the cornice shuttering car.

For such assemblies and disassemblies are usually and dismantling car used, which put on the cornices, like a bridge become. Such cars are expensive and hinder in terms of space, as they unload far.

PRESENTATION OF THE INVENTION

The invention is based on the problem of simplifying the assembly and disassembly of the guides for the cornice shuttering in generic formwork devices. The invention solves this problem according to claim 1, characterized in that in a generic formwork device, the guides for the cornice formwork car from sections of double guide rails best hen, on the one hand, on their upper sides spaced along the structure fastened or mounted upper chassis are movable and, on the other hand, on their undersides along the structure in the direction of travel spaced chassis of Gesimsschalungswagens, in particular rolling or sliding lead. The invention is therefore based on the idea to attach the cornice formwork carriage on their part movable double guide rails.

hereby Among other things, that is achieved for progression rail mounting all work with heavyweight components, especially the double guide rail mounting from a secured Position the cornice shutter wagon, and work with lighter ones Components, such as the fixtures and reel apparatuses, from a man basket out, which can be hung on the guide rail, can be done. On assembly or disassembly can can be omitted and the assembly and disassembly work can during concreting work of concrete bonding, d. H. at closed scraping done.

From the cornice formwork carriage, or as the rail installation progresses from the man basket, a plurality of sliding or wood body devices are anchored to the overhanging cornice underside individually or in a group. As a rule, only from the cornice shutter carriage sections of the double guide rail are placed on this slide or rolling elements and advanced. On the section of the double guide rail projecting from the cornice shutter carriage, a man basket can be pushed forward from the cornice shutter carriage, or the man basket is already fastened to the extended section of the foremost double guide rail, ie on the projecting end area, so that from there the next sliding section or Wälzkörperhalterung for the double guide rail can be anchored to the building cornices. In order to facilitate the insertion, the sliding or rolling elements can be releasably connectable in relation to anchor plates to be anchored to the cornices or openable for lateral attachment of the double guide rail sections. The connection to the anchor plate is preferably made pivotable to allow self-alignment of the double guide rail according to the appended loads and inclinations of the cornice underside. The disassembly of the double guide rails after a successful concreting can be done at the rear end of the cornice formwork carriage in reverse order as the mounting of the double guide rails. At the bottom of the double guide rail, the chassis of the cornice formwork carriage in a known manner z. B. as in the DE 91 07 201 U1 rolling or sliding movable.

At the cornice underside individually attachable sliding or Wälzkörperanordnungen are known for cornice formwork cars on the market. These must but from a separate lifting or crane platform or the like be mounted from or from the cornice formwork car. For the latter must the Gesimswagen after assembly of each guide or Wälzkörpereinrichtung be advanced a short distance, with the with the Cornice formwork rigidly connected mounting rail in the newly mounted Slide or rolling element arrangement moved into it is, so that this takes over the loads of cornice shuttering carriage, while at the rear end of the cornice formwork carriage that of the short mounting rail piece now relieved last sliding or Wälzköperanordnung must be dismantled. This known arrangement requires a comparatively time-consuming assembly and disassembly and this can even after a de-scaling step and a new formwork step begins only when over the entire length of the Cornice scarf, which is quite on the order of magnitude of 20 meters, gradually from attachment point to Attached attachment point and the mounting points mounted or dismantled. In this known cornice formwork car takes the support rail, which also takes over the guide rail function, all loads of cornice shuttering and concreting on. It is correspondingly large and heavy to handle. It also increases the weight load at the suspension points. The reel machines carry permanently the total load, which leads to large sizing.

In contrast, is achieved by the invention that a new support and guide rail piece on the total length of the next concreting section pre-assembled and the support and guide rail piece can be dismantled from the last concreting section while currently a concreting section prepared by shuttering, armored and executed, or during the Setting time of the concrete, while the cornice formwork under full load and immovable at the location of the concreting section is in use. The double guide rails are functional no contribution to stability for the cornice formwork car afford and can be slim and lightweight accordingly be executed. This also improves their handling.

It is now possible in various ways to further develop formwork devices according to the invention:
According to one embodiment of the invention is provided in a formwork device according to the preamble of claim 1, in particular according to claim 1, at least one Wagenlifteinrichtung for Anhe ben or to pivot the Gesimsschalungswagens with respect to the structure provided. On the other hand, the carriage lift device engages the building on its underside and, on the other hand, it engages with the cornice shuttering carriage and is designed to permit the cornice formwork to be held in its concreting position in a manner that relieves the guideway and the cornice formwork carriage to be moved in its travel position Allow process in a new concreting position. Such a vehicle lift device may comprise a piston / cylinder units with hydraulic drive, wherein the gesimsseitige attachment of the rail attachment points may also be provided independently to better distribute the suspended loads. In this case, the drive element, as the piston / cylinder unit does not need to attack directly on the corn side attachment point. Instead, fitting rods may be intercoupled. The attachment points for lifting must not be directly on the formwork beams but can also between adjacent formwork beams, z. B. at the connecting these tapes, ie be provided at an arbitrary position in the longitudinal direction of the structure. Such a lift device according to claim 3 is of inventive significance is not only causes an acceleration of the scarfing process, but also a relief of the landing gear of Gesimsschalungswagens, which can now be designed for improved runnability and is no longer inferior to the restrictions arising in the Cornice formwork car after the DE 91 07 201 U1 result in that the guides are also claimed by the burden of concreting.

reliefs The guide rails of cornice formwork cars are indeed in the form of anchor rods available on the market cornice formwork devices available, but do not allow a noticeable Swiveling the formwork beams between a concreting position and a demoulding position.

According to one Another embodiment of the invention is provided which Formwork devices to perform so that the guides on the building and / or the chassis on the cornice formwork carriage Transversely mounted transversely to the projecting edge of the trailer. Such a swinging attachment not only contributes at, the above-mentioned alignment of the guide rails with respect to to allow the cornice lower edge in automatic form. Rather, it makes it possible to position this the cornice formwork as well as the stripping easier to design by the cornice formwork carriage in the area of its support and guide rail by at least one along the building longitudinal extension approximately parallel pivot axis before and after a concreting step to pan. For example, then in a first pivoting movement to Relief of the construction side support wheels Relief bars are brought into position by pivoting, without an adjustment work is mandatory here.

One Swiveling the cornice shuttering cart as a whole in the sense of a Lifting the cornice shuttering causes following the procedure of cornice shuttering carriage in the position of the next Betonierabschnittes the resting Ge simsschalung by the Verschwenkschritt is pulled close to the building cornices, so immediately then with the introduction of the concrete reinforcement in the already finished aligned formwork can be started. As a pivot bearing can the guide suspension and / or the chassis attachment serve, while in the area of the support wheel a per se known variable-length prop the Pivoting effect or in the concreting position the pivoting position can fix.

If Both a Stützradentlastung and a Schalungsverschwenkung are desired, may alternatively or additionally a pendulous suspension of the guides and / or the chassis a certain height change in the guide rail area, z. B. by means of slots on the fasteners in the guide area, provided become. You can the Stützradentlastung in a first Swing step perform and then the now under the Built-up cornices due to the Stützradentlastung incurred new attachment point of the cornice shuttering wagon on the building cornices as Use the first support bearing as the fulcrum of the cornice formwork car is raised at its projecting end until the cornice circuit on the building cornices in the intended end position to the plant comes. A suitable for this pivoting device is below yet to be described. The pendulum mounting of the guides on the building and / or the chassis on the cornice formwork carriage are of independently inventive meaning. They shorten u. a. the set-up times for the cornice formwork considerably in the new concreting position.

The the aforementioned and the claimed and in the embodiments described to be used according to the invention Components are subject in size, shape design, Material selection and technical conception no special exceptions, so that the selection criteria known in the field of application unrestricted Application can be found

Further details, features and advantages of the subject matter of the invention will become apparent from the dependent claims, as well as from the following Description of the accompanying drawing and table, in which - by way of example - an embodiment of a shuttering device is shown.

DETAILED DESCRIPTION OF THE EMBODIMENT

From the 1 to 3 is a freely projecting edge area 10 a perpendicular to the surface of the image extended bridge visible. At this cornice is on the underside of a laterally projecting formwork device 100 on cast-in anchoring means 234 attached. The formwork device consists essentially of a cornice formwork carriage 110 , the formwork beam parallel or star-shaped to each other 112 includes, with spaced juxtaposed formwork support z. B. by straps 114A . 114B for forming the cornice shuttering carriage 110 connected to each other. The straps consist of conventional, spaced and parallel to each other arranged U-profile iron, which with the approximately horizontally extending below the cornice first formwork support legs 112A z. B. are firmly connected by screws or by welding. An outwardly facing end portion of the first formwork support leg 112A is by a pivot pin connection with a downward directed second formwork support legs 112B connected. This is essentially based on the strut 116A to form a fixed angular position. At him can a third formwork support leg 112C , which has a cantilever in approximately horizontal position to the outside, are articulated at different heights on suitable bolt connections, the length of a strut 116B between the second and third formwork support legs 112B and 112C the inclination of the third formwork support 112C sets. The second and third formwork support legs 112B . 112C carry first, second and third cornice formwork elements 118A , B and C, 118C the latter being tiltable from a fourth formwork support leg 112D with respect to the third formwork support leg 112C in inclination and distance is adjustable. Serve again for the usual holes with bolt connections and a strut 116C which is adjustable in length. lifting devices 120 Wear the third cornice formwork panel 118C and allow their fine adjustment.

A at the inner end of the first formwork support leg 112A arranged jockey wheel 122 rolls with approximately parallel to the formwork support 112 arranged axis of rotation on the cornice underside in a known manner from when the cornice formwork carriage 110 is moved to the next concreting position. In his Beto nierzustand the cornice formwork car 110 about a jockey wheel 120 disengaging pivot support on the cornice base.

The actual suspension and the method of cornice formwork car 110 serves a rail and chassis arrangement 200 , This consists essentially sections 210A from a double guide rail 210 , which is executed in the illustrated and so far preferred embodiment as a double-T-carrier. Upper and lower chassis 220A and 220B for the interaction with the top and bottom of the double guide rail 210 are by means of associated coupling elements 222A . 222B anchoring elements 224 or the cornice shuttering cart 210 pivotally connected. The upper and lower chassis 220A . 220B wear for resistance-resistant guidance along the double guide rail 210 Rolling elements in the form of known horizontally and vertically acting pairs of rollers on corresponding running surfaces of the double guide rail 210 unroll with a small amount of play. anchoring means 234 are already present on the cornice underside or are anchored there in a suitable manner. The one about it attached anchoring elements 214 carry over a bolt connection in a pivotable manner, the upper coupling element 222A which in turn is the upper chassis 220A carries or is integrally connected with this. The upper support and pivot pin 223A possibly also serves as a separation point of the double guide rail 210 from the anchoring elements 224 , That with the lower chassis 220B firmly connected or thus integrally formed coupling element 222B has a slot 221 a length of about 1 to 10 cm, preferably 2 to 6 cm in length, which is the lower coupling element 223B opposite the first formwork support leg 112A a limited vertical movement possibility and in conjunction with the lower support and pivot pin 223B forms a further pivot connection. The operation of the double guide rail 210 will be related to the 4 and 5 be explained.

Out 2 can be seen as in the concreting the support edge 122 by the optionally variable length swivel support 124 is replaced, the cornice shuttering plate 118A to the cornice 10 moved up and the Gesimsschalungsplatte 118C in its closed position to the cornice formwork panel 118B moved up and the first formwork support legs 112A concerning the long hole 221 has started up. By the latter is the double guide rail 210 from the weight load of cornice formwork car 110 and the concreting load of the edge cap 10A is completely relieved. If desired, these loads now hang over anchor rods 232 a tail on the anchoring elements 224 and other ends on the harness 114 , The lifting or pivoting movement, in which the concreting load is not or no longer carry, is by a piston / hydraulic cylinder unit as a lifting device 230 Allowing one end to the strapping 114 supports and the other ends of the anchoring element 224 towards the cornice with the end of a lanyard 230A releasably attached. After swiveling up the cornice shuttering cart 110 against the cornice 10 by lifting device 230 So can the weight load of Gesimsschalungswagens 110 and the fresh concrete on the adjacently arranged anchor rods 232 be taken while the double guide rail 210 as good as no load. In this no-load position, it is also recommended to install further sections 210A the double guide rail 210 in the direction of the next concreting section and the disassembly in the area of the preceding concreting section, as now on hand of 4 and 5 is explained.

In the 3 illustrated Entschalungs- and Verfahrposition of the elements of the formwork device corresponds to the reloaded state of the double guide rail 210 ,

How out 4 can be seen from the cornice formwork cars 110 out, new sections 210A the double guide rail 210 first to the anchoring elements 224 attached, and subsequently on the upper chassis 220A in the direction of the next concreting section, shown in the drawing with arrow M for mounting direction, advanced. Before that, first of cornice shuttering car 110 out, more anchoring elements 224 attached to the cornice underside. After a section 210A the double guide rail 210 attached to it, can be a man basket 240 at the double guide rail section 210A by means of at least one lower chassis, similar to the chassis 220A attached and handled. Towards the free end, a fall arrest device. From the man basket can be further anchoring elements 224 Fasten. Another double guide rail section 210A is advanced under displacement of the already mounted double guide rail sections in direction M until the next double guide rail section can be coupled in the resulting rail gap.

In the 5 showing disassembly situation shown by omitting the concreted cap, as shown by the man basket 240 out, the no longer required anchoring elements 224 be removed and no longer needed guide rail sections 210A be posted to the opposite end of the cornice shuttering cart 110 to be remounted.

From the in 6 illustrated detail view of an illustrated and so far preferred anchoring element 224 is a U-profile iron section recognizable, which has a cast-anchoring means 234 with the cornice 10 is connected at the bottom tensile strength. This anchoring element has at least one receptacle for the connection preferably made by screwing with an anchor rod 232 , Another recording allows a bolt via a train connection with the upper coupling element 222A , Whose pivotability with respect to the anchoring element 224 may be limited by attacks on one side or on both sides. Another shot 224C allows the anchoring element 224 with the upper end of a piston or connecting rod 230A Hub Submission 230 releasably connect. Thus, the embedded anchoring means 234 multifunctional in the various phases of the shuttering device used.
