Description

formwork

The invention relates to a formwork for producing a concrete element, in particular a wall or ceiling element, with a recess, in particular a window or door recess, comprising:

- a panel,

- A recess formwork with a frame element to limit a section of the recess, with a support bracket for supporting the frame element and with a bearing element for supporting the support bracket,

- A stripping device for transferring the Aussparungsscha development from a formwork position for forming the recess in a stripping position for releasing the concrete element.

Furthermore, the invention relates to a battery formwork with such a formwork and a further formwork element, wherein a formwork space is provided between the formwork panel of the formwork and the white direct formwork element.

Finally, the invention relates to a method for producing a concrete element, in particular a wall or ceiling element, with a recess, in particular a window or door recess, with the steps:

- Providing such formwork,

- Arranging the recess formwork in the formwork position,

- Pour the concrete element with the formwork and

- Separating the concrete element from the formwork.

As is known, for example, from DE 102198 96 CI, a recess formwork can be used to form an opening for a window, door or the like in a concrete component. The recess formwork is arranged on the formwork skins of an inner and an outer formwork. The recess formwork has a movable frame which is attached to a rigid inner frame. On the outer circumference of the Innenrah mens handlebars are formed, the frame sections of the Ausspa approximate formwork articulated. The handlebars can be swiveled so that the recess formwork is reduced in size and so the outer formwork can be removed from the concrete body created together with the recess formwork. To pivot the handlebars, spindles are provided, which can be extended or shortened ver. However, it is disadvantageous that demolding the concrete component is complex. The spindles must be adjusted so far that there is a sufficient distance between the frame sections of the recess formwork and the concrete component in order to be able to detach the formwork from the concrete body. A particular problem here is that the frame sections can adhere to the concrete component, as a result of which the formwork can be blocked from being pulled off. Another disadvantage is that the links and the spindles are exposed to high loads when concreting, which can lead to malfunctions.

In contrast, the object of the present invention is to alleviate or remedy at least individual disadvantages of the prior art. The aim of the invention is, in particular, to make it easier and more reliable to detach the concrete element from the formwork. Furthermore, an object of the invention can be to improve the transfer of loads during concreting ver.

This object is achieved by a formwork having the features of claim 1, a battery formwork having the features of claim 13 and a method having the features of claim 14. Preferred embodiments are given in the dependent claims.

According to the invention, the stripping device has a displacement and tilting mechanism for moving the frame element in a direction parallel to the formwork panel and for tilting the frame element about a pivot axis running essentially parallel to the formwork panel.

In order to prepare for releasing the concrete element from the formwork, the sliding and tilting mechanism of the stripping device is actuated. The sliding and tilting mechanism is set up to move the frame element in the direction parallel to the main plane of the formwork and at the same time the frame element to tilt the pivot axis running parallel to the main plane of the panel. Thus, the frame element can not only be moved along the inside of the formwork panel, but also tilted away from the inside of the formwork panel. This makes it much easier to separate the formwork and structural element after hardening. If the frame element adheres to the concrete element, the concrete element can still be separated from the formwork because the frame element is displaced and tilted at the same time. A blockage during demolding is thus reliably avoided. If the frame element does not adhere to the concrete element, it can be moved without tilting the frame element at the same time. However, it is essential that the stripping device is set up to enable both the displacement and the tilting of the frame element.

If the pivot axis of the sliding and tilting mechanism is essentially parallel to the longitudinal axis of the frame element, the frame element can be tilted away from the formwork when separating the Be tonelements from the formwork. As a result, the concrete element can be reliably removed from the formwork (or, conversely, the formwork can be pulled off the concrete element). In the formwork position, the frame element is preferably arranged essentially perpendicular to the inside of the formwork panel. If the frame element is tilted during stripping, the frame element is arranged in the stripping position at an angle to the inside of the formwork panel.

The frame element can preferably be tilted by at least 2 degrees, in particular at least 4 degrees, particularly preferably at least 6 degrees, while simultaneously being displaced away from the concrete element.

In order to enable the desired displacement and pivotability simply and reliably, the displacement and tilting mechanism of the stripping device preferably has a longitudinal guide, in particular an elongated hole, and a guide element, in particular a bolt, mounted therein so as to be displaceable and pivotable, with the longitudinal guide on one of the support bracket and La gerelement and the guide element on the other of the support bracket and Bearing element is provided. The longitudinal guide is preferably formed on the support bracket and the guide element on the bearing element. However, the reverse arrangement can also be provided. By shifting the guide element along the longitudinal guide with simultaneous pivoting of the guide element about the pivot axis, the frame element is shifted inward and tilted away from the formwork panel. The desired degrees of freedom of movement are thus achieved in a particularly simple manner. The transfer to the stripping position can be carried out particularly quickly, since laborious actuation of spindles as in the prior art is not required. Under the influence of gravity and / or contact with the concrete element, the transition from the shuttering to the shuttering position can be jerky. Preferably, all degrees of freedom of movement of the frame element except for the displacement along the formwork panel and the tilting about the pivot axis are blocked parallel to the formwork panel.

In order to release the tilting movement of the support bracket during the transfer into the stripping position and therefore not to block it, the support bracket according to a preferred embodiment variant has a rounded portion at the end area facing the pivot axis to free the pivoting of the support bracket.

In order to ensure the formation of the recess on the concrete element, the recess formwork preferably has a securing element for securing the support bracket in the formwork position. In the secured state of the securing element, the recess shuttering is secured against being transferred from the shuttering position to the shuttering position. In the unlocked state of the securing element, the transfer from the switch position to the disconnection position is released. Thus, the concrete element can be poured in the secured state of the securing element in the receiving space of the formwork adjacent to the formwork panel. After the concrete element has hardened, the securing element is brought into the unlocked state in order to be able to transfer the recess formwork from the formwork to the stripping position.

To secure and unlock the securing element can be via a detachable connection, in particular via a screw connection, be connected to the bearing element. The formwork can be prepared by loosening the detachable connection. Conversely, the releasable connection is made to enable the casting of the Be tonelements with the recess. The releasable Ver connection of the securing element can therefore be made reversibly, ie without loss of functionality, and preferably without tools, and can be solved.

In order to make the assembly particularly simple, reliable and fast, the screw connection in a preferred embodiment has a threaded bolt, in particular essentially in the center of the bearing element, the securing element having a holding opening for placing on the threaded bolt. In this embodiment, the screw connection preferably has a retaining nut which fixes the securing element placed on the threaded bolt on the bearing element. The threaded bolt is preferably arranged essentially perpendicular to the main plane of the formwork panel, which on the one hand facilitates the placement of the securing element and on the other hand the attachment of the retaining nut. It is also advantageous if the securing element has a retaining plate on which the retaining opening is formed. This embodiment has the particular advantage that the sliding and tilting mechanism in the secured state of the securing element can be covered at least partially, preferably essentially completely, by the retaining plate. This increases the safety during operation. In the secured state, the retaining plate is preferably arranged essentially perpendicular to the threaded bolt and essentially parallel to the formwork panel. The bearing element preferably has a bearing plate which is attached to the formwork panel. In this embodiment, it is advantageous if the retaining plate of the hedging element has essentially the same shape and extent as the bearing plate of the bearing element, the holding plate and the bearing plate being arranged essentially congruently in plan view, perpendicular to the panel.

The bearing element, in particular a bearing plate of the bearing element, is preferably fastened to the formwork panel via a screw connection, for example with a threaded bolt. However, a magnetic connection can also be provided. In order to reliably block the displacement or tilting of the frame element in the shuttering position, the securing element in a preferred embodiment has a first holding surface for contact with an outer side of the support bracket facing away from the panel and / or a second holding surface for planting an end face facing away from the frame element of the support angle. Preferably, the second holding surface of the hedging element is designed as a wedge surface. This design acts reliably securing the frame element in the shuttering position in order to enable the precise formation of the recess in the concrete element.

In a preferred embodiment, the bearing element has at least one first wedge surface and the securing element has at least one second wedge surface, with the second wedge surface of the securing element resting against the first wedge surface of the bearing element in the secured state of the securing element. In the secured state, the first and second wedge surfaces are angled to the inside of the formwork panel, i.e. at an angle other than 90 degrees, for example at an angle of 70 or 110 degrees. The bearing element preferably has at least two, in particular four, first wedge surfaces and the securing element has at least two, in particular four, second wedge surfaces. The first and second wedge surfaces run before given in the direction away from the inside of the formwork of the auseinan. The first wedge surfaces preferably delimit a receiving opening into which a section of the securing element, in particular a projection on the underside of a retaining plate of the securing element, is inserted with the second wedge surfaces. The first wedge surfaces form corresponding run-up surfaces for the second wedge surfaces of the securing element in order to make it easier to attach the securing element to the bearing element. It is also advantageous that the first and second wedge surfaces bring about effective bracing of the securing element on the bearing element.

In order to attach several frame elements to the same bearing element, in a preferred embodiment the bearing element has at least two, preferably four, bearing points for the storage of two, preferably four, support brackets. At least one pair of bearing points is preferably provided for two support brackets, which hen wegste in opposite directions from the bearing element. Thus, two opposite boundaries of the recess from the concrete element can be formed. Depending on the design, however, three support brackets can also lead away from three bearing points at right angles to one another in order to form three boundaries of a rectangular recess in the concrete element. Furthermore, four bearings can be arranged in pairs at right angles to one another. If support brackets are arranged at all four bearing points, all four boundaries of a rectangular recess can be formed. Thus, two, three or four support brackets can be arranged at the bearing points of the bearing element, to which a corresponding number of frame elements be fastened to form two, three or four boundaries of a rectangular recess of the concrete element.

In a preferred embodiment, the bearing points each have at least one holding flange with a bearing opening. The retaining flange is preferably arranged essentially perpendicular to the switchboard. The guide element, in particular the bolts, of the displacement and tilting mechanism is preferably mounted on the bearing opening. It is also advantageous if the bolt is released bar, in particular releasable without tools, is attached to the bearing opening. The bolt can be secured to the bearing opening with a cotter pin. Thus, the associated Tragwin angle can be easily detached from the bearing element if the corresponding bearing should not be occupied with a support bracket for the current application.

According to a preferred embodiment, the formwork has a further formwork panel, the formwork panel and the further formwork panel being pivotally connected to one another at their first end regions, so that the formwork panel and the further formwork panel can be converted from a standing state to a lying state. A "butterfly shuttering" with two pivotable shuttering elements is known, for example, from WO 2016/184947 A1. The two preferably rectangular shuttering panels are each pivotably connected at a first end area, in particular on one of their longitudinal sides. For this purpose, an articulated connection between the first end of the formwork panels can be provided. As a result, the two formwork panels can be transferred from a standing state in which the formwork elements are preferably aligned essentially vertically to a lying state in which the formwork elements are preferably aligned essentially horizontally. In the standing state, the first end areas form the upper ends of the formwork elements and the second end areas form the lower ends of the formwork elements. In the horizontal position, for example, the recess formwork can be mounted on the panel.

The formwork is preferably used in a battery formwork, which has a further formwork element, wherein a formwork space is provided between the panel of the formwork and the white direct formwork element. The additional formwork element can be a single formwork panel. Alternatively, two further formwork elements can be pivotably connected to one another at their first end regions, as was explained above in connection with a preferred embodiment of the formwork.

In this case, the formwork space is formed between the formwork and one of the further formwork elements. Of course, such a battery formwork can be expanded as required by formwork and other formwork elements to form several formwork spaces for the production of several concrete elements. To produce a concrete element, in particular a precast concrete part, the formwork can be arranged in the standing state of the formwork between two bulkheads of the battery formwork. The formwork panels are in the collapsed (i.e. essentially parallel to one another) state.

In the method for producing a concrete element, in particular a wall or ceiling element, with a recess, in particular a window or door recess, at least the following steps are carried out, preferably in the specified order:

- Providing a formwork according to one of the embodiments described above, - Arranging the recess formwork in the formwork position,

- pouring the concrete element with the formwork,

- Separation of the concrete element from the formwork,

- At least one frame element of the recess formwork is displaced when separating the concrete element from the formwork in a direction parallel to the formwork panel and is tilted about a pivot axis extending substantially parallel to the formwork panel.

For pouring the concrete element, a further formwork element is preferably arranged opposite the formwork panel, the recess formwork being located between the formwork panel and the further formwork element. The concrete element is preferably poured in a battery formwork which has the formwork and the further formwork element.

The invention is explained below with the aid of a preferred exemplary embodiment, to which, however, it is not intended to be restricted.

Fig. 13 shows a battery formwork in which the formwork according to the Invention can be used.

Fig. 1 shows a formwork device, in the following for short Scha treatment 1, for the production of a (in Fig. 2 visible) concrete element 2, which is in particular a rectangular wall or ceiling element. The formwork 1 has a formwork panel, ie a formwork panel 3, which has an inside 4 to delimit a receiving space for concrete and an outside 5 facing away from the receiving space (see FIG. 2). The inside 4 and the outside 5 of the formwork panel 3 are essentially flat. On the inside 4 of the panel 3 is a recess shuttering 6 is arranged with which a window or door Recess 7 is formed on the concrete element 2. The recess shuttering 6 has at least one frame element 8 which delimits a straight section of the recess 7. In the embodiment shown, four frame elements 8 are arranged at right angles to each other in order to lay a rectangular recess 7 Festzu. The frame elements 8 are each connected via at least one support bracket 9 to at least one bearing element 10, which is attached to the inside 4 of the formwork panel 3. In the embodiment of FIG. 1, each frame element 8 is connected to two bearing elements 10 via two support brackets 9.

As can be seen from Fig. 2, a stripping device 11 is seen before, with which the recess formwork 6 of a in Fig.

I and Fig. 2 shown formwork position for concreting the concrete element in a stripping position shown in FIGS. 3, 4 for releasing the concrete element 2 from the formwork 1 can be moved. The stripping device 11 has a displacement and Kippme mechanism 12, which is set up to push the frame element 8 in a direction 13 parallel to the panel 3 to ver (see double arrow 13 in Fig. 3) and a substantially union parallel to tilt to the formwork panel 3 extending pivot axis (see. Double arrow 14 in Fig. 3). In the embodiment shown, the pivot axis of the sliding and tilting mechanism 12 runs parallel to the longitudinal axis 15 of the frame element 8 (see FIG. 1).

The sliding and tilting mechanism 12 of the stripping device

II has a longitudinal guide 16, here an elongated hole, in wel chem a guide element 17, here a bolt, is displaceable and pivotable. In the embodiment shown, the longitudinal guide 16 is provided on the support bracket 9 and the guide element 17 on the Lagerele element 10. The support bracket 9 has a rounded portion 18 (i.e. a rounded outer contour) at the end area facing the pivot axis adjacent to the inside 4 of the formwork panel 3, with which the pivoting of the support bracket 9 is enabled.

As can be seen from FIG. 2, the formwork 1 also has a securing element 19 (not shown in FIG. 1) for securing the support bracket 9 in the formwork position. The safety element Ment 19 is connected to the bearing element 10 via a releasable connection, in the embodiment shown via a screw connection. The screw connection has a threaded bolt 20 which is fixed in the center of the bearing element 10. The securing element 19 has a holding opening 21 (cf. FIG. 8) for placing on the threaded bolt 20. The safety element 19 also has a first holding surface 22 for contact with the outside 9a of the support bracket 9 facing away from the panel and a second holding surface 23 for contact with an end face 9b of the support bracket 9 facing away from the frame element 8. In addition, the bearing element 10 has a first wedge surface 24 on which a second wedge surface 25 of the hedging element 19 rests in the secured state.

In the embodiment shown, the bearing element 10 has four bearing points 26 on which at least one support bracket 9 and up to four support brackets 9 (including a corresponding number of frame elements 8) are arranged. The bearings 26 each have two retaining flanges 27 with bearing openings 28, on which a bolt 29 for the bracket 9 can be detachably attached. The bolt 29 can be secured with a cotter pin 30.

As can be seen from Fig. 1, the recess formwork also has corner formwork parts 31 which are arranged at the corners between two adjacent frame elements 8 of the recess formwork.

In Fig. 5 and Fig. 6, a variant is shown in which an additional mounting bracket 33 between the frame element 8 and the support bracket 9 is provided.

The sequence during stripping can be seen from FIGS. 7 to 10.

In the hardened state of the concrete element 2, the corner formwork parts 31 of the recess formwork are first dismantled (see FIG. 7). Then a retaining nut 32 is released, which is screwed onto the end of the threaded bolt 20 in order to hold the hedging element 19 on the bearing element 10 (see. Fig. 8). Since after the securing element 19 is removed from the bearing element 10 (see Fig. 9). As a result, the displaceability and pivotability of the frame elements 8 is enabled. The concrete element 2 can thus be lifted away from the formwork 1. Just by contact with the concrete element 2, the frame element 8 can be shifted and tilted in such a way that the lifting of the concrete element 2 is not blocked.

Fig. 1 shows a schematic representation of a battery formwork 34 known for example from WO 2017/174432 with formwork devices 35 which have the formwork 1 described above.

The battery mold 34 is used for the production of structural elements (not shown in FIG. 1) and in particular of precast concrete parts for buildings. The battery mold 34 has a support frame 36 with spaced-apart support sections 37. The number of support sections 37 in FIG. 1 is only to be regarded as an example and can be adapted to the circumstances. Furthermore, the battery shuttering 34 comprises two Tragein directions 38, in which the bulkheads 39 and the Schalungsein directions 35 are suspended and moveable, that is, in the present embodiment, slidable. The shuttering devices 35 are located between the bulkheads 39. A cavity to be filled with concrete is formed between at least one bulkhead 39 and a shuttering device 35, with the shuttering device 35 preferably not bearing shuttering elements that determine the contour of the precast concrete part . The formwork elements can, for example, delimit doors or window cutouts and also seal the cavity filled with concrete during concreting. The Schalele elements can be attached to the Schalungsein device 35 with magnetic holders, for example. In addition, a heating device (not shown) and / or a vibrator (not shown) can also be mounted on the formwork device 35. The Schalungseinrich device 35 is used between two bulkheads 39 and braced with them during concreting. The number of Tra geinrichtung 38 of the bulkheads 6 and the Schalungseinrichtun gene 2 is to be regarded as exemplary only and can be varied depending on the circumstances. For example, formwork devices 35 for concreting the outer walls, inner walls, des The floor and the roof of a house can be provided so that the components for an entire building can be produced simultaneously with the battery mold 34. The bulkheads 39 and the formwork devices 35 are clamped between two Abstützeinrich lines 40. The number of support devices 40 is also to be regarded as only exemplary and can be varied according to requirements. At least one support device 40 is movably, that is to say displaceable in the present embodiment, accommodated in the support devices 38. For stabilization, the formwork devices 35 and the support devices 40 can be connected to one another and braced in the concreting position by one or more rod-shaped connecting devices 41. The number of connecting devices 41 can be adapted to the circumstances. Instead of rod-shaped connecting devices 41, hydraulic connecting devices are also possible. The rod-shaped connecting devices 41, however, are particularly robust and easy to use. Furthermore, the battery formwork 34 has a lifting device 42 with which at least one of the formwork devices 35 can be transferred from the lowered concreting position to a raised transport position, in which the formwork device 35 is essentially in one direction via a formwork device 35 in the concreting position can be conveyed perpendicular to the lifting direction. In the case of the battery formwork 34, the formwork devices 35 are hooked into the support devices 38 from above, so that in the hooked-in state in the concreting position between the Auflageab 37 are spaced from the ground. The design of the lifting device 42 can be adapted to requirements. If necessary, several lifting devices 9 can also be used.

The lifting device 42 can be moved in a tensioning direction of the formwork devices 2 on two spaced-apart guide devices 43, which are designed here as running rails. Furthermore, the guide devices 43 are arranged above the support devices 38 and parallel to them. In order to make the battery formworks 34 more compact, the formwork devices 35 are attached to the support devices 38 at their upper end. Instead of known formwork devices 35 as shown in WO 2017/174432, the formworks 1 according to the invention can be accommodated in the battery formwork 34.
