- a first lever arm between the rod axis and the pivot axis, running perpendicular to the rod axis and the pivot axis, has a first lever arm length that is smaller than a second lever arm length of a second lever arm between the rod axis and the pivot axis, the perpendicular to the rod axis and the joint axis.
- the rod axis In the shuttering state, i.e. shuttering and/or shuttering state, of the shuttering element, the rod axis can be arranged essentially vertically, with a linear movement of the pull rod relative to the base element leading to the at least one shuttering/removing element being moved into the shuttering position .
- a linear downward movement of the pull rod relative to the base element can result in the at least one shuttering/opening element being extended into the closing position.
- the status of the shuttering/dismantling element extended into the shuttering position is shown in the In the following referred to as the shuttering state of the formwork element and the state of the shuttering/opening element moved into the formwork-opening position is referred to in the following as the open state of the formwork element.
- the drive unit can be arranged externally from the stripping device and/or the formwork element and can be designed, for example, as a hydraulic unit, pneumatic unit or, if the lifting device comprises a spindle lifting gear, as an electric motor.
- the stripping device After a completed tilting movement of the tilting element, the stripping device allows, with an existing attachment of the boom to the piston end section of the lifting device and a continued lifting movement in the same direction that led to the tilting movement of the tilting element, with a lever arm caused by the tilting element on the boom compared to the first enlarged lever arm caused by the jib without the tilting element, that the jib without tilting element with the enlarged lever arm takes over the introduction of force into the push/pull rod of the jib with tilting element.
- the tilting movement of the tilting element can be ended, for example, by a stop of the tilting element which rests against the boom from a predetermined tilting angle.
- the force for moving the push/pull rod can be applied efficiently and for the base element via the lever arm, which is longer than the first lever arm for breaking loose the on/off formwork element from the concrete, and the lifting device and the outer section of the base element of the formwork element resting against the contact element of the first formwork element and the stripping device are introduced gently into the base element, so that no permanent deformations occur on the base element and the stripping device due to the shuttering and/or stripping of the formwork element.
- the introduction of the lifting force of the lifting device of the first stripping element via the first lever arm of the second stripping element, which is shorter than the second lever arm, into the pull/push rod for moving the pull/push rod into the stripping position of the on/off formwork element, together with the design of the tilting element, allows such that it can be supported directly or indirectly on the base element when the cylinder section of the lifting device from the base element moved away, the lifting device and the base element are gently introduced into the pull/push rod, so that the stripping forces required for stripping can be introduced without damaging the formwork element/corner formwork element.
- the lifting device of the first stripping element can be driven by a drive unit integrated into the lifting device or arranged externally by the first stripping element.
- the drive unit can be present and used in the form of a hydraulic unit that is present on a construction site.
- the gentle and efficient introduction of the lifting force into the push-pull rod with the first lever arm, which is shorter than the second lever arm, allows the use of an external drive unit available on the construction site.
- the contact element of the first stripping element is designed such that the piston end section of the lifting device can move away from the base element when the cylinder section of the lifting device is supported on the base element via the contact element resting on the formwork element. In this way, the abutment element ensures that the first stripping element abuts against the base element gently and sufficiently for the introduction of the lifting force into the push-pull rod. Since the boom can also be attached to the rod end section of the pull/push rod, the stripping device can be retrofitted to the formwork element/corner formwork element.
- the contact element and the lifting device can be present separately from one another or as an integrated part.
- the boom made of steel or aluminum, for example, can be designed as a solid body and can be made up of one or more components, with a design as a hollow body also being possible.
- the stripping device Without the drive unit, the stripping device can have a compact design and can be installed on the formwork element/corner formwork element easily and without a great deal of manual effort.
- the first and second stripping elements may be in integrated form or in separate form that can be coupled.
- the basic element in formwork is also used as a synonym for a basic corner element of a corner formwork element and vice versa, with the on/off formwork elements coupled to the basic corner element on both sides being activated by a linear movement of the push/pull rod, the rod axis of which when the corner formwork element is in the formwork state, in particular in Is arranged substantially vertically, relative to the basic corner element in an on or off formwork or retractable.
- the boom can have a handle element that can be reversibly fastened to the rod end section, the handle axis of which runs essentially coaxially or parallel to the rod axis, and a cantilever arm element that protrudes from the handle element and is rigidly connected to the handle element, to which the tilting element is rotatably coupled about the tilting axis.
- a stick length of the stick member may be selected such that when the boom is attached to the rod end portion, the cantilever arm member and the tilting member are located outside of the base member. If the rod end section is arranged inside the base element, the handle element allows the push/pull rod to be "extended" to the outside of the base element in order to rigidly connect the cantilever arm element projecting from the handle element to the handle element.
- the handle length can be selected in such a way that that the cantilever arm element is connected perpendicularly to the handle element.
- the handle element can be designed as a cylindrical hollow body, e.g. made of steel or aluminum.
- the cantilever arm element can be designed as a solid body and made up of one or more components, e.g. made of steel or aluminum. A Formation as a hollow body, e.g., made of steel or aluminum, is also possible.
- the rigid connection between the stem element and the cantilever arm element can be detachable from one another, e.g., by means of a screw connection, or fixed, e.g., by means of a weld seam.
- a lifting axis of the lifting device can run essentially parallel to the handle axis and the lifting device can be spaced apart from the handle element by essentially the second lever arm length, so that the first stripping element and the second stripping element form a U-shaped form.
- the overall height projecting beyond the outer surface of the basic element can in this case result from the height of the tilting element and/or the cantilever outside of the basic element.
- the overall height projecting beyond the basic element can be approx. 144 mm when the lifting device is fully retracted and approx. 250 mm when the lifting device is fully extended.
- the first stripping element can be designed in such a way that when the second stripping element is fastened to the rod end section, a contact element end section of the contact element, which is arranged below the outer surface of the base element, attaches itself to a rigid sheet metal element of the base element between frame legs, via which the at least one closing/opening element the pull/push rod is coupled, supports in order to bring about a support torque introduction into the rigid sheet metal element.
- a compact design results from the fact that a lifting axis of the lifting device runs essentially parallel to the shaft axis and the lifting device is spaced apart from the shaft element by essentially the second lever arm length, so that the first and second stripping elements form a U-shape.
- an overall height of the stripping device outside of the base element can essentially be given by a height of the tilting element.
- the tilting element has a support section for supporting on the base element in a first section of the tilting element, which is related to a surface with the rod axis and a normal vector perpendicular to the tilting axis, a second section of the tilting element is opposite, in which the tilting element is rotatably coupled to the boom about the tilting axis.
- the support section can thus provide support for the first lever arm during a lifting movement for stripping the shuttering element, without impairing the effect of the first lever arm when the lifting force is introduced into the push/pull rod.
- One horizontal fixation of the tilting element can be achieved, which leads to a stable movement of the tilting element and thus the push/pull rod.
- An edge of the support section of the tilting element facing the handle element can at least partially adjoin an outside of the handle element facing the edge with a contact distance, the contact distance being selected such that the outside of the handle element can be moved without friction on the edge of the support section.
- the first lever arm can be used for introducing the lifting force into the push/pull rod without being lengthened due to an avoidable distance of the support section from the stick axis.
- a central tubular profile stiffener can be used to avoid permanent deformation of the basic element.
- a horizontal force can be introduced into pressed-in flanged sleeves of a frame profile of the basic element.
- the pressed-in flanged sleeves represent a local doubling of material and are therefore more suitable for the introduction of horizontal forces without permanent deformation than areas of the basic element with a simple wall thickness.
- a particularly advantageous embodiment is when the first stripping element comprises a wearing layer element, which can be designed in particular as a horseshoe-shaped plate, which is arranged at least between the contact element and the first section of the tilting element in the area of the support section when the tilting element is on the piston end section of the lifting device is rotatably coupled about the hinge axis.
- the supporting force of the supporting section of the tilting element can thus be introduced into the wearing layer element of the first stripping element instead of into an outer surface of the basic element, which avoids permanent deformation of the basic element or at least reduces it compared to an embodiment of the stripping element without wearing layer element.
- the cantilever When the cantilever is attached to the rod end portion, the cantilever is advantageously in a region protruding from the push/pull rod, in particular a area protruding from the pull/push rod on a boom end section, can be coupled to the piston end section of the lifting device in such a way that, on the one hand, a third lever arm running perpendicularly to the rod axis between the rod axis and the piston end section of the lifting device has a third lever arm length that is greater than the first lever arm length of the first lever arm, and on the other hand with a continued lifting movement of the lifting device in a direction a force in the push/pull rod essentially parallel to the rod axis for stripping first from the tilting element into the jib using only the first lever arm and subsequently from that Boom is initiated using only the third lever arm.
- the third lever arm which is longer than the first lever arm, the lifting device and the outer surface of the base element, a reduced tensile or compressive force of the lifting device for the base element compared to the first lever arm can be gently and effectively introduced into the push/pull rod and permanent deformation of the base element and/or the stripping element can be avoided.
- the jib has an elongated hole oriented in the direction of the lifting movement in the area protruding from the push/pull rod and a pin element coupled to the piston end section of the lifting device through the elongated hole, in particular in the lorrn of a bolt. is passed through, which is rotatably coupled to the tilting element about the hinge axis of the tilting element in such a way that the third lever arm corresponds to the second lever arm.
- the tilting element can advantageously have the shape of a clamp with two legs, which are connected to one another in particular at both ends, in which the cantilever is arranged, the tilting axis being formed by a rod element, in particular in the shape of a bolt, which is formed by the two legs and passed through the boom.
- the lifting device is designed from the drive unit in Lorrn a hydraulic unit, pneumatic unit, a Screw jacks with a rotary motor, in particular an electric motor, or to be driven manually by means of a crank or ratchet, or by a combination thereof.
- Hydraulic units are often already available on a construction site for use in a climbing system, for example.
- the drive unit is arranged externally to the lifting device, the stripping device can be designed to be compact and light-weight so that it can be manually mounted on the base element. In this way, the installation of the stripping device is made easier and work safety is increased compared to an embodiment with a drive assembly comprised by the lifting device.
- the stripping device can have a valve device connected between the hydraulic unit and the lifting device, which includes either cylinder and piston-side load-holding valves and a piston or cylinder-side pressure relief valve or cylinder and piston-side check valves and a piston or cylinder-side pressure relief valve.
- Load-holding valves on the cylinder and piston ensure that the hydraulic cylinder of the lifting device operates independently of external events, e.g. B. STOP Hydraulic unit, pressure loss in a hydraulic line, external load action, remains in its respective lifting position, which provides a safety function without uncontrolled movement of the formwork.
- a piston-side pressure relief valve causes an overload sifting function such that when the applied oil pressure exceeds the permissible operating level z. B. 190 bar, the pressure is automatically derived from a supply line to a return line without damaging connected components or the lifting device and / or hydraulic unit itself.
- a simple way of using the stripping device together with other stripping devices is when the valve device is connected to the hydraulic unit by means of a first pair of couplings for supply lines and a second pair of couplings for return lines, in particular with T-pieces integrated in the valve device and/or supply and return lines is. There may be four visible ports, two ports being an inlet coupler pair and the other two terminals form a reverse clutch pair.
- the stripping devices can be connected with simple standard hoses, e.g. B. by quick release, connected and disconnected from each other, which is conducive to work efficiency on the construction site.
- a load-optimized, uncontrolled oil supply can take place in the form of a ring supply line, in which the principle of least constraint is at work. It is up to the oil volume in which cylinder the pressure builds up first.
- the formwork elements are initially loosened with less holding resistance, until finally the maximum oil pressure (with the highest degree of efficiency) is available for the more strongly adhering formwork elements be ensured.
- the tilting element can have a lifting eyelet.
- the lifting eye can lie in a first section of the tilting element which, based on a surface with the rod axis and a normal vector perpendicular to the tilting axis, is opposite a second section of the tilting element in which the Tilting element is rotatably coupled to the boom about the tilting axis.

- the contact element 5 has the wear-resistant layer element 8 in a horseshoe shape, which is arranged on an upper contact element section 5a1 of the contact element 5, with a lower contact element section 5a2 of the contact element 5 being arranged parallel and offset in the Y-direction to the wear-resistant layer element 8 and the upper contact element section 5a1 .
- the lower contact element section 5a2 has a horseshoe shape with an opening in the negative X direction, so that the first stripping element 1a can be mounted on the basic corner element 2 in such a way that a vertical introduction of force into the negative Y-direction can take place directly on a welding sleeve of a tension/compression pipe guide of the frame profile of the basic corner element 2.
- the first stripping element 1a is assembled using two screw connections which can be made using bolts B1, B2 which can be inserted in the negative Y direction and which can be secured using circlipsZ pins.
- a tubular profile stiffener that is central relative to the push/pull rod 3 can be used in this way for the stable installation of the first stripping element 1 a on the basic corner element 2 .
- the contact element 5 also has a contact element end section 5b, which allows a supporting moment to be introduced into welded-in rigid sheet metal elements between frame legs, which are arranged on the basic corner element 2, around the on/off formwork elements 4a, 4b on the basic corner element 2 to pair.
- the contact of the contact element end section 5b on the rigid sheet metal element between the frame legs of the corner formwork element can provide support in the negative X-direction by means of a cantilever effect (see also the arrangement of the first stripping element 1a on the corner formwork element as shown in Figures 1b and 1c ). Due to the alignment of the contact element 5 in the X direction with a contact surface in the x/z plane and an alignment of the lifting device 6 with the valve device VV and the connection element 7 perpendicular to the contact element 5 in the negative Y direction, a design results for the first stripping element 1a, which requires assembly on an upper frame profile of the Basic corner element 2 essentially parallel to the push/pull tube 3 allowed.
- the result is a low overall height of the stripping device 1 above the basic corner element 2, which is essentially determined by an overall height of the tilting element 11 and can be 144 mm when the lifting device 6 is fully retracted and 250 mm when the lifting device 6 is fully extended.
- FIG. 2b shows a three-dimensional external view of the second stripping element 1b, with the rod element SA acting as a tilting axis A1 and the pin element S1 acting as a joint axis A2.
- the tilting element 11 is rotatably coupled to the boom arm element 10b of the boom 10 via the tilting axis A1 and the tilting element 11 can be coupled to the piston end section 6a of the lifting device 6 of the first stripping element 1a via the joint axis A2.
- the stick element 10a of the boom 10 is in the form of a hollow cylinder with the stick axis 10a1.
- the tilting element 11 has a support section 11a for supporting on the basic corner element 2, which is shown in Figures 1a to 1c, in a first section of the tilting element 11, which relates to a surface with the stem axis 10a1 and a Normal vector perpendicular to the tilting axis A1 opposite to a second section of the tilting element 11 by the tilting element 11 being rotatably coupled to the cantilever arm element 10b about the tilting axis A1.
- the lifting eye KOE is arranged in the first section of the tilting element 11, in which the support section 11a is arranged.
- the tilting element 11 has two legs which are oriented in the X direction and are spaced apart from one another in the Z direction such that the cantilever arm element 10b can be arranged between the legs of the tilting element 11. In this way, a design with low material costs for the tilting element 11 with high stability of the tilting element 11 and a low design of the tilting element 11 can be achieved. In this way it is also possible that the articulation axis A2 is not only used to couple the tilting element 11 to the piston end section 6a, but also via the same articulation axis A2 a section, in particular end section, of the extension arm element 10b to the piston end section 6a couple. In Fig.
- a side view of the stripping device 1 is shown combined with a cross-sectional view of the tilting element 11 to show a side view of a section of the boom 10 with a slot LL oriented in the Y-direction.
- the piston end section 6a is fully retracted into the cylinder section 6b of the lifting device 6 in such a way that the pin element S1 forming the articulation axis A2 bears against a lower edge in the negative Y-direction of the long hole LL.
- a first lever arm HA1 running perpendicularly to the rod axis 3a and the tilting axis A1 between the rod axis 3a and the tilting axis A1 has a first lever arm length HL1 which is smaller than a second lever arm length HL2 of a second lever arm HA2 between the rod axis 3a and the joint axis A2, perpendicular to the rod axis 3a and the joint axis A2.
- the support section 11a is in contact with the wear-layer element 8 in such a way that an outer surface of the support section 11a facing the wear-layer element 8 is parallel to one of the support section 1 1 a facing outer surface of the wear layer element 8 is available.
- the tilting element 11 is first rotated counterclockwise relative to the cantilever arm element 10b, with the cantilever arm element 10b and thus the cantilever 10 rest.
- force is introduced into the push/pull tube 3 in such a way that, during a stripping process, the force is first released by means of a tilting movement of the tilting element 11 relative to the boom 10 with the first lever arm HA1 with the first lever arm length HL1 takes place and then, when the elongated hole LL has been passed through by the pin element Sl, the force is no longer introduced via the tilting element 11, but via the extension arm 10 into the push/pull rod 3, with a second lever arm HA1 being extended to the first Lever arm HA2 with a lever arm length HL2 that is greater than the first lever arm length HL1 is used.
- a is therefore initially smaller first lever arm HA1 with a large introduction of force into the pull/push rod 3 for breaking the corner formwork element away from the concrete lying against it during stripping, and after the corner formwork element has broken away from the concrete, the tilting element 11 automatically becomes the boom 10 due to the mechanical arrangement an extended second lever arm HA2 is provided with a force that is introduced into the push/pull rod 3 that is smaller than the first lever arm HA1.
- the lifting device 6 can be used for a load-optimized, automatically controlled lever arm adjustment during the stripping process.
- the effect of a small lever arm initially present during a stripping process and a large lever arm then present when the lifting movement for stripping is continued can also be present if the boom 10 is not connected to the tilting element 1 1 is connected.
- the tilting element 11 no longer rests against the basic corner element 2 via its support section 11a in order to introduce the force of the lifting device 6 into the push/pull rod 3 via the lever arm HA1, but the tilting element 11 moves in Y- Direction for stripping is lifted from the basic corner element 2, the further introduction of force no longer takes place automatically via the first lever arm HA1, but via the second lever arm HA2.
- the tilting element 11 can only be coupled to the boom 10 via the tilting axis A1 and to the piston end section 6a via the articulation axis A2.
- the tilting element 11 can be designed such that after a tilting movement has been carried out by a predetermined angle, a section of the tilting element 11 rests against the boom 10 such that a further tilting movement is prevented.
- the tilting element 11 With a further lifting movement in the Y-direction for stripping, the tilting element 11 is no longer tilted relative to the boom 10, but the force is then introduced via the larger lever arm HA2 and the boom 10, since the smaller lever arm HA1 is no longer able to do so To introduce force into the push/pull rod 3.
- a force in the pull-Z-push rod 3 is initiated in such a way that the stripping process can take place without permanent deformation of the basic corner element 2 and/or boom 10.
- a permanent deformation of the basic corner element 2 can be avoided or at least reduced compared to the prior art while the basic corner element 2 of the corner formwork element is breaking away from the concrete using the first lever arm HA1, by having an edge of the supporting section 11a of the tilting element facing the handle element 10a 11 without contact at least partially adjoins an outside of the stem element 10a facing the edge with a contact distance at which the outside of the stem element 10a can be moved just without friction on the edge of the support section 11a.

- the lifting movement is introduced into the pull/push rod 3 via the first lever arm HA1 shown in FIG.
- the lifting force is not introduced via the cantilever arm element 10b by means of the second lever arm HA2, since the pin element S1 is located centrally within the elongated hole LL and thus a force transmission from the piston end section 6a to the cantilever arm element 10b does not take place.

Since the pin element S1 is not yet in contact with the upper edge of the elongated hole LL in the Y-direction, the first lever arm HA1 for introducing the lifting force into the push/pull rod 3 is still used to introduce the force.
- a distance between the support section 1 1 a and the wear layer element 8 d51 indicates that the tilting element 1 1 can no longer be supported via the support section 1 1 a on the basic corner element 2 in order to transfer lifting force to the push/pull rod via the first lever arm HA1 3 to initiate.
