Definitions

the present invention relates to a method and a device for positioning and/or removing fixing elements on/from a formwork base, as well as a fixing element for use in combination with the device, both individually and in combination as a system.
the invention is preferably used in a precast concrete plant in which prefabricated concrete parts are produced on a production line - so to speak "on the assembly line".
formwork with formwork is placed on a magnetic or magnetizable formwork base by a formwork robot.
Reinforcing and usually magnetic fixing elements are positioned on the formwork base, which must be removed separately from the formwork base after the formwork has been filled with liquid concrete and the finished, hardened concrete part has been removed.
Such fixing elements are used, for example, to fix concrete installation elements on the formwork base and are to be distinguished from those concrete installation elements that are embedded in the concrete when the formwork is filled with liquid concrete after the prefabricated concrete parts have been completed and are removed from the formwork base.
fixing elements are positioned individually by hand on the formwork base and, after use, are removed again individually from the formwork base by hand or with lever rods. Positioning and removing the fixing elements by hand proves to be time-consuming and uneconomical, since, among other things, considerable forces have to be applied to remove the fixing elements from the formwork base (the holding force to be overcome when lifting is usually around 50 to 100 kg).
the present invention is based on the object of providing a method and a device for positioning and/or removing fixing elements on/from a formwork base, as well as a fixing element for use in combination with the device, both individually and in the system, in order to improve the work for a worker when positioning and/or removing fixing elements on/from the formwork base, so that the cycle times on a production line for the semi-automated production of precast concrete parts in a precast concrete factory can be significantly shortened.
the invention provides the method according to claims 1 and 2, the device according to claim 9, the fixing element according to claim 14 and the system according to claim 15.
the fixing elements are moved as a group into the intended position on and/or above the formwork base, separated there and positioned on the formwork base.
a separate collection step for each individual fixing element can be eliminated by moving all fixing elements as a group into the intended assembly position on/above the formwork base.
the fixing elements can be separated from the group independently of one another in different positions and positioned on the formwork base.
the fixing elements are moved as a group in a housing designed as a magazine above the formwork base and/or positioned individually on the formwork base from the housing designed as a magazine.
the fixing elements can be collected one after the other, particularly automatically, and removed as a group from a formwork base and transported to a delivery station. This eliminates the need for transport routes for individual fixing elements to the delivery station.
the fixing elements are preferably in a magazine designed housing collected and / or removed as a group from the formwork base in a housing designed as a magazine.
step A includes at least one of the following sub-steps: Substep A1: Grouping at least two fixing elements to form the group of fixing elements, preferably in a stacked assembly along a stacking axis, preferably in such a way that the fixing elements are arranged regularly and/or in contact with one another, particularly preferably in the most compact stacked assembly.
Substep A1 Grouping at least two fixing elements to form the group of fixing elements, preferably in a stacked assembly along a stacking axis, preferably in such a way that the fixing elements are arranged regularly and/or in contact with one another, particularly preferably in the most compact stacked assembly.
Substep A2 Recording the group of fixing elements in a device for positioning fixing elements on a formwork base, preferably in a device according to one of claims 9 to 13, preferably from/in a position next to the formwork base.
a further group of fixing elements can be provided in a starting position or refill station while individual fixing elements are being positioned on the formwork base.
the further/second group can be picked up in the starting position or refill station after all fixing elements of the first group have been used up. Accordingly, several steps of the method can be carried out in parallel with each other.
Substep A3 Actuating an engagement device to establish an engagement between the engagement device and the fixing element to be separated, preferably electrically, hydraulically, pneumatically and/or mechanically.
the separating device is preferably part of the device and is moved with the group of fixing elements into the intended assembly position for the fixing element to be separated.
Substep A4 Aligning at least one fixing element within the group of fixing elements with respect to at least one other fixing element of the group of fixing elements, preferably by correcting the relative position and/or orientation of the fixing elements, preferably by centering on an axis, particularly preferably by magnetic force.
This embodiment proves to be particularly advantageous with regard to the reliable and error-free separation of the fixing elements from the group of fixing elements.
Substep A5 Aligning at least one fixing element from the group of fixing elements with respect to the formwork base, preferably by arranging the stacking axis exactly or substantially perpendicular to the formwork base. As a result, a positioning error when placing the fixing element to be positioned on the formwork base can be minimized.
Substep A6 Moving at least one fixing element from the group of fixing elements parallel and/or perpendicular to the formwork base, preferably with a robot.
a positioning error when placing the fixing element to be positioned on the formwork base can be further reduced.
the fixing element can be positioned on the formwork base with millimeter precision using a robot.
Substep A7 Placing the device for positioning fixing elements on the formwork base, preferably a device according to one of claims 9 to 13.
a positioning error of the fixing element to be positioned which may be caused by uncontrolled movements of the device in a floating state above the Formwork underlay could arise can be minimized.
step B includes at least one of the following sub-steps:
the fixing elements can be held in contact with one another, for example by magnets, in order to minimize relative displacement to one another.
This group network is ideally only broken down when a fixation element is separated, so that the position of the fixation element to be separated can be controlled as best as possible up to the separation step.
Substep B2 Moving at least the fixing element to be isolated and/or at least one other fixing element from the group of fixing elements, preferably perpendicular to the formwork base, preferably along the stacking axis, preferably by the action of the weight force.
Substep B3 Positioning the fixing element to be separated, preferably the lowest fixing element in the stacking direction, on the formwork base, preferably by the action of the weight force and / or by the action of the magnetic force between the formwork base and the fixation element.
Substep B4 Establishing an engagement between a remaining fixing element from the group of fixing elements, preferably the second fixing element from below in the stacking direction, with the engagement device, so that this fixation element is held in engagement by the engagement device.
the fixing elements that are stacked on the fixing element positioned on the formwork base are lifted off together in stack formation.
Substep B5 Separating the fixing element to be separated from at least one remaining fixing element of the group, preferably by relative movement of both fixing elements, in particular along the stack axis, preferably with dissolution of the group.
Substep B6 Output of the isolated fixing element from the device, preferably the device according to one of claims 9 to 13, preferably in said position.
step B* at least one remaining fixing element of the group is moved into at least one further position above the formwork base that is different from the said position, preferably step B and optionally step B* being repeated in each further position , preferably until the last fixing element of the group is positioned on the formwork base, with steps A, B and optionally step B* particularly preferably being repeated with at least one further group of fixing elements.
the method according to the invention proves to be particularly economical because in one operation - without a separate approach to the starting position or refill station - several fixing elements can be positioned independently of one another on the formwork base.
step C has at least one of the following sub-steps:
Substep C1 Placing a device for positioning and/or removing fixing elements on/from the formwork base, preferably a device according to one of claims 9 to 13, onto the formwork base.
the force for lifting the fixing element from the formwork base can be applied to the fixing element particularly well and in a targeted manner.
Substep C2 Actuation of an engagement device to produce an engagement with the fixing element to be removed from the formwork base, preferably electrically, hydraulically, pneumatically and/or mechanically. This allows the effect on the fixing element to be removed from the formwork base to be controlled as best as possible.
Substep C3 Receiving the fixing element to be removed from the formwork base in a device for positioning and/or removal of fixation elements on/from a formwork base, preferably a device according to one of claims 9 to 13.
the fixation element to be removed from the formwork base stored safely in the device and protected from external influences. This allows the effect on the fixing element to be removed from the formwork base to be further improved.
Substep C4 Aligning at least one fixing element within the group of fixing elements with respect to at least one other fixing element of the group of fixing elements, preferably by correcting the relative position and/or orientation of the fixing elements, preferably by centering on an axis, particularly preferably by magnetic force.
reuse of the fixing element removed from the formwork base and its repositioning on the formwork base are made easier.
Substep C5 Arranging the fixing element to be removed from the formwork base and at least one further fixing element of the group of fixing elements in the stacked assembly along a stacking axis, preferably in such a way that the fixing elements are arranged regularly and/or in contact with one another, particularly preferably in the most compact stacked assembly. In this embodiment, reuse of the fixing element is made even easier.
step D has at least one of the following sub-steps: Substep D1: Moving at least the fixing element removed or to be removed from the formwork base and optionally the remaining fixation elements of the group of fixation elements, preferably in a translational movement parallel and / or perpendicular to the formwork base, and / or a rotational movement about a parallel or perpendicular to the formwork base Axis, preferably with a robot. Through such movements, the fixing element removed or to be removed from the formwork base can be controlled particularly well.
Substep D2 Lifting the device for positioning and/or removing fixing elements on/from the formwork base, preferably a device according to one of claims 9 to 13.
automation of the method is particularly simple.
steps A and B may be repeated as often as desired after steps C and D have been carried out with the same fixing elements. Accordingly, the fixing elements previously removed from the formwork base can always be repositioned on the formwork base.
a further independent aspect of the present invention relates to a device for positioning and/or removing fixing elements on/from a formwork base, preferably by carrying out the method according to one of the preceding claims, wherein the device for receiving a group of fixing elements and for engaging with a fixing element , in particular with a fixing element to be positioned on the formwork base and / or a fixation element to be removed from the formwork base.
This device can be moved manually by a worker or automatically, for example by a formwork robot, into any position on and/or above the formwork base.
the device preferably comprises a magazine designed as a magazine Housing for moving the group of fixing elements over the formwork base and/or for removing the group of fixation elements from the formwork base.
the device may make sense for the device to have an exchangeable adapter, with the device preferably being configurable either for manual operation or for robot operation by exchanging the adapter.
the device according to the invention can be used in a variety of ways.
the device has a housing and a carrier, the housing and carrier preferably being coupled so that they can move relative to one another. Due to the movable coupling of the housing and carrier, a mechanical trigger for the actuation of an engagement device for producing an engagement with at least one fixing element can be created in a simple manner.
the device has an engagement device for producing an engagement with at least one fixing element, which is preferably electrically, hydraulically, pneumatically and / or mechanically actuated, preferably coupled to a relative movement between the housing and the carrier, wherein a contact between the engagement device and at least one fixing element is selectively produced or released by actuating the engagement device, the engagement device particularly preferably having at least two movable engagement sections for producing engagement with at least one fixation element, the engagement sections most preferably via a joint coupled between the housing and the carrier - and/or toggle lever mechanism are controlled simultaneously.
the device is adjustable between a configuration for positioning fixing elements on a formwork base and a configuration for removing fixation elements from a formwork base, preferably by transferring an adjusting device between a retracted position and an extended position. This makes the device more versatile.
the device 1 according to the invention according to the present exemplary embodiment is used for positioning and removing fixing elements 2 on/from a formwork base 3 and comprises a housing/magazine 11 for receiving a group of fixing elements 2 and a carrier 12, as well as an engagement device 13 for producing an engagement with a fixing element 2.
the housing 11 is tubular, for example made of aluminum/stainless steel (non-magnetic) and comprises two, for example, plate-shaped arms 112, which protrude from the hollow cylindrical base part 111 essentially radially to the central axis M, possibly with an upward taper at the end, and for example through Welding is connected to the base part 111.
the interior of the base part 111 preferably tapers conically along the central axis M from top (support 12) downwards (adjusting device 14) in order to center the fixing elements 2 stored in the interior in relation to the central axis M and in precise position in detail below to supply the engagement device 13 described.
Two guide elements/buttons 115 extend parallel to the central axis M on the inner wall of the housing 11 and are spring-elastically biased into an extended position in a direction parallel to the central axis M in order to rest on the formwork base 3.
the guide elements/buttons 115 are designed to engage in the recesses 24 of the fixing elements 2 and to guide them against rotation in the housing 11 when moving along the central axis M, to place them in the correct orientation on the formwork base 3 and again in the correct orientation from the formwork base 3 in the housing 11 to accommodate.
the carrier 12 is designed as a tube that is concentric with the base part 111 of the housing 11 and is intended to be held in a supporting manner by a worker, so that the housing 11 is arranged hanging under the carrier 12.
another adapter can be attached via the wings 122 projecting laterally from the base part 121 of the carrier 12 via a screw cap 124, which is designed, for example, as a hollow square tube with an edge length of 60 mm, in order to be picked up by a formwork robot in the same way as a formwork to become.
Other adapters or suspensions of the device 1 are also conceivable.
Attached to the underside of the base part 121 are two further wings 125 which extend radially to the central axis M and are connected to joint rods 131 for coupling the movement of the carrier 12 relative to the housing 11.
the engagement device 13 comprises two slide-shaped engagement sections 134, which can each be brought into positive engagement with a fixing element 2.
the two engagement sections 134 are arranged offset by 180 ° to the central axis M, designed to be mirror-symmetrical and can be actuated simultaneously in order to enclose a fixing element 2 on the neck 22 or between the head 21 and the torso 23 in a form-fitting manner, without play and completely.
the number of engagement sections 134 is not necessarily limited to two.
each engagement section 134 is coupled to a relative movement between housing 11 and carrier 12 via a joint/toggle lever mechanism formed from lever rod 131 and lever 132 as well as further deflection rods and joints 133 in such a way that when the total length of housing 11 and carrier 12 is shortened, each Engagement section 134 is spaced from the central axis M. In the event of a relative movement between the housing 11 and the carrier 12, which increases their overall length, the distance of the engagement section 134 from the central axis M shortens.
the engagement device 13 is automatically actuated when the housing 11 is placed on the formwork base 3 and from the closed position to the open position transferred, while the engagement device 13 is also automatically actuated when the housing 11 is lifted from the formwork base 3, but is thereby transferred from the open position to the closed position.
the inside diameter of a circle is which form the sides of the engagement sections 134 facing the central axis M, the smaller the outer diameter of the head 21 and the body 23 of the fixing element 2, so that the fixation element 2 is fixed in both directions along its axis A in a form-fitting manner and preferably without play between the engagement sections 134.
the opening formed between the engagement sections 134 is larger than the outer diameter of the head 21 and the body 23 of the fixation element 2, so that the fixation element 2 is out of the effective range of the engagement device along its axis A, which preferably coincides with the central axis M of the device 1 13 can be moved.
the strength of the engagement device 13 is dimensioned such that a lifting force aligned perpendicular to the contact side of the fixation element 2 can be applied to the fixation element 2 via the engagement sections 134 in order to overcome the magnetic holding force of preferably approximately 87 kg.
the central axis M ideally corresponds to the axis A of the fixation element 2 held in engagement and the stacking axis S, along which the fixation elements 2 can be stacked in the housing 11 with a regular arrangement and orientation (contact side facing downwards).
the adjusting device 14 is essentially tubular, for example made of aluminum/stainless steel (non-magnetic) and is arranged concentrically outside the base part 111 of the housing 11 along the central axis M in an adjustable manner relative to the latter.
the adjusting device 14 comprises a hollow cylindrical base part 141 with at least one guide groove to form a link guide with a guide pin 114 which projects radially outwards from the base part 111 of the housing 11.
the base part 141 includes two further guide grooves to form a link guide with the arms 112 projecting radially outwards from the base part 111 of the housing 11.
the adjusting device 14 is adjustable between a retracted position and an extended position.
the base part 141 of the adjusting device 14 can be fixed relative to the base part 111 of the housing 11 in the retracted position or the extended position using a button 142.
a button 142 At the lower end of the base part 111 of the housing 11, four feet 143, which define the footprint of the device 1, extend essentially parallel to the central axis M.
the device 1 can be configured between a function for positioning fixing elements 2 on a formwork base 3 (extended position of the adjusting device 14) and a function for removing fixing elements 2 from a formwork base 3 (retracted position of the adjusting device 14).
the engagement device 13 can be brought into engagement with a fixing element 2 positioned directly on the formwork base 3.
the engagement device 13 can be brought into engagement with a fixing element 2, which is placed or stacked on the fixing element 2 positioned directly on the formwork base 3.
the engagement height of the engagement sections 134 in the retracted position of the adjusting device 14 is dimensioned in relation to the footprint of the device 1 such that the engagement sections 134 form the neck 22 or the constriction formed between the head 21 and the torso 23 of the fixing element 2 in the closed position , free of play and completely enclosed.
the engagement height of the engagement sections 134 is dimensioned in relation to the installation surface of the device 1 in such a way that the engagement sections 134 positively lock the fixing element 2, which is placed on the fixing element 2 positioned directly on the formwork base 3, in the closed position , free of play and completely enclosed.
Fixing element 2 described is intended for use as a system in combination with the device described above.
the fixing element 2 comprises a mushroom-shaped upper part 2a made of a non-magnetic material, in particular stainless steel or aluminum, and a substantially cylindrical lower part 2b.
the upper part 2a of the fixing element 2 forms a head 21 and a neck 22, while the lower part 2b forms a body 23.
the neck 22 is arranged between the head 21 and the body 23 and forms a taper for a positive connection, for example with a concrete installation element, as well as for the positive application of a force to lift the fixing element 2 from the formwork base 3.
the head 21 and the body 23 each include one that rejects the contact side Cone 21a, 23a to facilitate attachment of the engagement device 13 or insertion into the housing 11 of the device 1.
Head 21, neck 22 and body 23 each comprise a cylindrical lateral surface 21b, 23b, which points radially away from the axis A of the fixing element 2, which is perpendicular to the contact side.
the change in cross-section between head 21 and neck 22 forms a radially projecting and circumferential flange 21c, which can be brought into engagement with the engagement device 13 of the device 1.
Semi-cylindrical recesses 24 in the lateral surface 21b, 23b of the fuselage 23 form an anti-rotation device 24 for the positive connection of the fixing element 2, for example with a concrete installation element, and for securing the same against rotation about an axis perpendicular to the contact side, as well as for anti-rotation guidance on the guide elements/buttons 115 in the case 11.
a cylindrical magnet 2d for fixing the fixing element 2 on the formwork base 3 is located centrally on the contact side of the fixing element 2 in a complementary cavity of the lower part 2b.
Another magnet 2c is arranged on the side of the fixing element 2 facing away from the contact side in a complementary cavity of the upper part 2a.
This further magnet 2c is smaller than the magnet 2d for fixing the fixing element 2 on the formwork base 3 and generates a smaller magnetic force.
the lower part 2b has a larger diameter than the upper part 2a and forms the contact side for the fixation element 2 to rest on the Formwork base 3.
the upper part 2a and the lower part 2b are separate components made of different materials and are connected by a screw which extends through a central hole 2e of the fixing element 2 and into both magnets 2c, 2d.
the axes A of the fixing elements 2 are aligned with the central axis M as the movement progresses in the direction of the engagement device 13 by guiding the cylindrical lateral surface 23b of the body 23 on the inner wall of the housing 11 and the recesses 24 on the guide elements/buttons 115 centered, and the fixing elements 2 are fed to the engagement device 13 in a precise position, so that the engagement sections 134 in the closed position can penetrate into the constriction of the fixation element 2 formed between the head 21 and the torso 23.
the filling of the housing 11 can be measured from above by a laser or recognized in some other way.
the neck 22 of the fixing element 2 has a non-rotationally symmetrical, preferably polygonal outline in cross section to the axis perpendicular to the contact side, based on which the fixing element can be aligned about this axis.
the outline of the neck 22, which is polygonal in cross section, is, for example, star-shaped and has four concave recesses on the outside, which taper towards the axis and are arranged symmetrically around the axis at regular angular distances of 90 °.
the engagement sections 134 of the device 1 have arrow-shaped tips that are convex in shape to complement the concave recesses on the neck 22 of the fixing element 2 have outlines. As a result, the fixing element 2 can be aligned around the axis when the two arrow-shaped engagement sections 134 engage in two diametrically opposite recesses.
a group is formed from individual fixing elements 2 and arranged regularly in the most compact stacked group, for example in such a way that the contact sides of the fixing elements 2 each point downwards.
the group of fixing elements 2 is fixed in this stack assembly, for example with packing tapes. This ideally happens in the factory and outside the formwork device 3 (step A1).
the mutual magnetic attraction of the fixing elements 2 supports the stack-shaped arrangement of the same and holds them together in the stack assembly in an arrangement aligned along the stack axis S without external influence.
the fixing elements 2 in this stack assembly are received along a stacking axis S from above or from below in the housing 11 of the device 1, so that the contact sides of the fixing elements 2 are downwards or point to the engagement device 13 (substep A2).
the stacking axis S ideally coincides with the central axis M of the device 1.
the fixing elements 2 are centered on the central axis M and in the exact position of the engagement device as the movement progresses along the central axis M in the direction of the engagement device 13 13 supplied.
individual fixing elements 2 in this stacked assembly become relative other fixing elements 2 of the group accommodated in the housing 11 (substep A4).
This proves to be helpful because, among other things, an offset of the fixing elements 2 with respect to the central axis M is possible through jerky movement of the device 1.
the play of the fixing elements 2 in the magazine M should be dimensioned sufficiently to enable reliable separation of the fixing elements 2 by the engagement device 13 without tilting or jamming in the housing 11.
the lowest fixing element 2 in the stacking direction is in engagement with the engagement sections 134 of the engagement device 13 that are in the closed position and is held in positive engagement and without play by the engagement sections 134 (substep A3).
the device 1 is now picked up with a formwork robot (not shown) on the adapter of the carrier 12 and moved over the formwork base 3 (step A6), so that the housing 11 is arranged hanging under the carrier 12 and the central axis M and stacking axis S are aligned exactly or essentially perpendicular to the formwork base 3 (step A5).
a formwork robot not shown
the device 1 is moved by the formwork robot parallel and/or perpendicular to the formwork base from the position P0 to a position P1 for separating and positioning a first fixing element 2 (substep A6).
the housing 41 of the device 1 is placed on the formwork base 3 (step A7).
the adjusting device 14 is in the extended position.
the fixing elements 2 fall through the released opening of the housing 11 onto the formwork base 3 and are thereby moved along the stacking axis S moves (substep B2) until the fixing element 2 to be separated rests on the formwork base 3 and is positioned in position P1 (substep B3).
the distance between the installation surface of the housing 11 or the formwork base 3 and the engagement height of the engagement sections 134 along the central axis M is dimensioned in the extended position of the adjusting device 14 in such a way that in the open position of the engagement sections 134 exactly one fixing element 2 fits through the opening, in order to rest on the formwork base 3 with its contact side.
the fixing element 2 following along the stack axis or the second fixing element 2 from below is held at the engagement height by the fixing element 2 resting directly on the formwork base 3 at a distance from the formwork base 3 and still in the engagement area of the engagement sections 134.
the device 1 is then lifted off the formwork base 3 with the formwork robot 1 and is moved perpendicular to the formwork base 3 in a direction away from the formwork base 3.
the engagement sections 134 move back into the closed position when the housing 11 of the device 1 is lifted off the formwork base 3, the engagement sections 134 engage the second fixing element 2 from below.
step B4 When the device 1 is lifted off the formwork base 3, the engagement sections 134 of the engagement device 13 are consequently transferred back from the open position to the closed position, so that the second fixing element 2 in the stacking direction is held in engagement from below by the engagement sections 134 of the engagement device 13 and when the device is lifted off 1 is held by the formwork base 3 through the engagement sections 134 in the housing 11 (step B4).
the fixing element 2 positioned on the formwork base 3 and to be separated is separated and separated from the remaining fixing elements 2 by relative movement relative to the fixing elements 2 remaining in the housing 11 along the stacking axis S, thereby dissolving the stack assembly (substep B5).
the fixing element 2 is individually released from the housing 11 in the position P1 (substep B6).
a step B* at least one remaining fixing element 2 of the group is moved into at least one further position P2 above the formwork base 3 that is different from said position P1.
Step B and optionally C can be repeated in every further position P2 until the last fixing element 2 of the group is positioned on the formwork base 3.
Steps A, B and optionally C can be repeated with at least one further group of fixing elements 2.
the device 1 is moved to the starting position P0 or to a refilling station next to the formwork base 3.
the empty device 1 is placed from above onto a stack of fixing elements 2 provided or exchanged for a filled device 1 provided.
the lowest fixing element 2 is placed on a pedestal 4 with a height matched to a fixing element 2, so that this lowest fixing element 2 is held in the engagement area of the engagement sections 134 of the engagement device 13. Accordingly, the lowest fixing element 2 contacts the engagement sections 134 when the housing 11 of the device 1 is lifted from the starting position or refill station P0, when the contact sections 51 move back into the closed position.
a formwork 5 formed on the formwork base 3 is filled with liquid concrete while embedding the fixation elements 2 and the fixation elements 2 are removed separately from the formwork base 3 after the finished concrete part has been lifted off.
the device 1 is brought into the configuration for removing the fixing elements 2 from the formwork base 3 by moving the adjusting device 14 into the retracted position and moved into the position P1 of the fixing element 2 to be removed from the formwork base 3.
the engagement device 13 is then actuated by placing the device 1 on the formwork base 3 to produce an engagement with the fixing element 2 to be removed from the formwork base 3 (partial steps C1 and C2).
the fixing element 2 to be removed from the formwork base 3 is received in the device 1 (step C3).
the fixing element 2 to be removed from the formwork base is aligned with a fixing element already accommodated in the device 1 (substep C4).
the fixing element 2 to be removed from the formwork base 3 is arranged with the fixing element 2 already stored in the device in the stack assembly along a stacking axis S regularly and in contact with one another (substep C5).
the engagement device 13 By lifting the device 1 from the formwork base 3, the engagement device 13 is transferred from the open position to the closed position.
the fixing element 2 to be removed from the formwork base 3 is engaged by the engagement device 13 and moved with the remaining fixation elements 2 of the group of fixation elements 2 perpendicular to the formwork base 3 (substep D1).
the lifting of the device 1 is preferably carried out with a formwork robot (substep D2).
