  • Holding devices for fixing concrete components in a mold for laying concrete wall elements in a formwork trough can be used in precast concrete works.
  • the holding devices for fixing concrete components in a mold which are also used, among other things, as formwork devices can be used in manual manufacturing processes, in partially automated or fully automated manufacturing processes.
  • the formwork devices are also referred to, among other things, as pallets, which are particularly suitable for being able to be moved from one work station to the next work station in an automated production plant.
  • a wall element prefabricated in the formwork trough which is then already in the form of hardened concrete, so that the hardened wall element can be fed to a second formwork trough, specifically in an upside-down position, i.e. in particular in a position turned by 180 degrees Orientation of the prefabricated wall element.
  • This can, for example, be the production of double wall elements, in which a prefabricated first wall element in hardened concrete, which forms one side of the double wall element, is brought in a turned orientation to a second wall element, which is still unfinished as fresh concrete, leaving a gap to attach the first wall panel to the second wall panel.
  • the prefabricated first wall element is permanently connected to the second wall element by curing of the fresh concrete of the second wall element, with the space in the double wall element being retained.
  • the prefabricated double wall element can then be joined to other double wall elements on site and the gaps filled with in-situ concrete.
  • the formwork trough forms a mold into which the fresh concrete is poured in order to produce the desired wall element.
  • the bottom of the formwork trough forms a preferably flat formwork table on which edge formwork elements can be attached or placed, which define the contour for the desired wall element and secure the fresh concrete poured into the formwork trough from flowing out of the formwork trough.
  • the edge formwork elements can be permanently installed edge formwork elements on at least one side edge of the formwork table.
  • the edge formwork elements can also be flexibly attachable edge formwork elements, which can be connected to the formwork table in a lockable and detachable manner.
  • Such flexibly attachable edge formwork elements can be magnet-integrated edge formwork elements, for example.
  • the edge formwork elements can also be fixed or flexibly attachable inner edge formwork elements.
  • These inner edge formwork elements can define recesses in the wall element to be manufactured, such as windows or doors.
  • the inner edge formwork elements can, for example, according to DE 10 2013 108 792 B4 be trained.
  • the formwork table is rotatably mounted in such a way that the formwork table can be turned from a filling position for introducing fresh concrete into the formwork trough into an inverted ejection position for the hardened wall element in hardened concrete.
  • the formwork table can in particular be turned by 180 degrees, so that the hardened wall element lying on the formwork table can be turned upside down, ie brought into an upside-down orientation.
  • a turning system can be used to turn the formwork table.
  • the turning system can have a portal-like basic structure with, for example, opposite rotary bearings on which the formwork table is mounted so that it can rotate or pivot about a central axis.

  • a frame of several edge formwork elements configured according to the size and shape of the wall element to be manufactured form a peripheral edge closure of the formwork trough, arranged sealed against one another. Sealing is only necessary to such an extent that it is ensured that the liquid fresh concrete does not escapes from the formwork trough in an undesired manner, ie flows out.
  • the edge formwork elements can specify an outer contour of the wall element to be manufactured and can hold the fresh concrete in the formwork trough during manufacture in the filling position of the formwork table.
  • the edge formwork elements can also specify the inner contours of the wall element to be manufactured, such as windows, doors and other functional openings, such as ducts or shafts.
  • the hardened wall element contained therein In order to turn the hardened wall element into its ejected position, the hardened wall element contained therein must be secured while the formwork table is being rotated so that it does not fall out of the formwork trough at an undesirable time due to gravity alone.
  • retaining rods have been used for this purpose, which are supported on the very outer edge sections of the formwork table.
  • These handrails are pushed in or set manually to the appropriate position and then mechanically and/or automatically hydraulically braced.
  • the manual work in this process requires considerable physical exertion, since the handrails have to be very solid due to the unfavorable lever ratios.
  • the weights of the handrails are only to be handled with the appropriate work aids and guides.
  • the invention comes in and proposes several securing means that are distributed over the peripheral edge closure of the formwork trough and that are positioned on the tops of the edge formwork elements.
  • at least one securing means can be provided on at least one side edge, for example on two side edges, in particular two opposite side edges or on any side edges, such as on each of the four side edges of the wall element.
  • two or more securing means can also be arranged on each side edge.
  • a plurality of securing means can in particular be arranged at equal distances from one another.
  • Each securing means is between a locking position, in which the securing means overlaps the wall element on its free wall surface opposite the formwork table, and an unlocking position, in which the Securing means the free wall surface of the wall element fully releases, adjustable mounted on the edge formwork elements.
  • the securing means are therefore not supported on the outer edges of the formwork table, but directly on the edge formwork elements.
  • the edge formwork elements determine the contour of the wall element to be manufactured and accordingly the securing means according to the invention are always supported on the edge formwork elements close to the contour of the wall element to be manufactured. The securing means can thus be made very compact.
  • the securing means are mounted on the edge formwork elements, the securing means can be moved together with these edge formwork elements, for example in the case of flexibly attachable edge formwork elements, in particular magnet-integrated edge formwork elements, if a wall element of a different size is produced in a second production run or shape is to be manufactured.
  • the wall element In the locking positions of the securing means, the wall element is retained in its inverted ejected position by the securing means in the formwork trough, i.e. the wall element rests on the securing means and the wall element is thus retained in the formwork trough.
  • the wall element In the unlocking positions of the securing means, the wall element is no longer retained in the formwork trough by the securing means in its inverted ejected position, i.e. the wall element can no longer be supported on the securing means since the securing means are withdrawn, and the wall element is thus released from the formwork trough, ie the wall element can become detached from the formwork trough.
  • the ejection process will take place in such a way that the wall element, which located in the formwork trough and held in the locking positions by the securing means, is turned over so that the formwork trough is arranged over the wall element.
  • the wall element which is already in the form of hardened concrete, is then placed or placed on a second formwork trough, in which there is a second wall element in fresh concrete.
  • spacers and/or built-in parts are generally provided, which keep the hardened wall element, which is present as ready-mixed concrete, at a predefined distance from the fresh concrete.
  • the securing means are moved from their locking positions to their unlocking positions.
  • the formwork trough can then be removed upwards, as a result of which the wall element is detached from the formwork trough and the hardened wall element, which is present as ready-mixed concrete, remains on the spacers.
  • the wall element is ejected by pulling the formwork trough upwards from the wall element.
  • the securing means overlaps the hardened wall element from the outside, a minimal overlap is sufficient for a form-fit securing of the wall element. This is very advantageous, for example, in the production of insulated or multi-layer double walls. Another advantage of the minimal overlap is that interfering edges from reinforcement, spacers and built-in parts do not have to be taken into account. The wall elements can thus be manufactured in higher quality.
  • the respective securing means can be designed, in its locking position, only the wall element to overlap in an outer edge area or inner edge area, whereby the width of the overlapping area of locked securing means and wall element is smaller than the thickness of the wall element, in particular the wall element in the overlapping area has no built-in parts, spacers, reinforcements and/or other elements with projecting edges.
  • the securing means are designed to overlap the wall element only in an outer edge area or inner edge area in their locking positions, with the width of the overlapping area of the locked securing means and wall element being smaller than that Thickness of the wall element, in particular the wall element in the overlapping area has no built-in parts, spacers, reinforcements and/or other elements with projecting edges.
  • the respective securing means can be formed by a rigid plate which extends with its main planes at least essentially parallel to the free wall surface of the wall element, the rigid plate being mounted in a form-fitting manner perpendicular to the main planes on an edge formwork element.
  • the rigid plate represents an at least essentially cuboid body, the width and depth of which is several times greater than the height, ie the thickness of the plate.
  • the panel is wider than it is deep.
  • the panel can extend with its width, ie with its greatest longitudinal extent, along, ie parallel to, the longitudinal extent of the edge formwork element assigned to it. It is sufficient for the panel if it is only slightly larger than the width of the associated edge formwork element.
  • the panel can be adjustably guided with its opposite outer edge regions, which limit the width of the panel, on the associated edge formwork element.
  • the main planes of the slab are determined by the largest side surfaces of the slab and result from the areas that span the width and depth of the slab.
  • the plate thus extends essentially parallel to the upper surfaces of the associated edge formwork element or parallel to the free wall surface of the wall element.
  • the free wall surface of the wall element to be manufactured and the slab lie in a substantially horizontal plane.
  • the rigid panel Due to the positive mounting of the rigid panel perpendicular to the main planes on the edge formwork element, the rigid panel is in the ejection direction of the wall element, i.e. in the vertical Direction of gravity, positively fixed.
  • an adjustment of the rigid plate in a direction perpendicular to the ejection direction is still possible, so that the rigid plate can be moved between the locked position and the unlocked position.
  • the movement of the rigid panel between the locked position and the unlocked position may be a linear movement. If necessary, the movement can also have a rotating movement component.
  • the rigid panel In addition to its form-fitting mounting perpendicular to its main planes, the rigid panel can also be held in a direction of movement parallel to its main planes in its respective locking position by friction on an edge formwork element.
  • a frictional connection in a direction of movement parallel to their main planes in their respective locking position can ensure that the rigid plate remains in its locking position when it has been brought into the locking position, in particular actively. Due to such a frictional connection, the rigid plate can be prevented from unintentionally releasing itself from its locked position. In other words, with such a frictional connection, a minimum force is required in order to be able to move the rigid plate out of its locked position.
  • At least one of the edge formwork elements can be designed as a magnet-integrated edge formwork element, which has at least two magnets that can be adjusted within the edge formwork element between an activation position and a deactivation position be actuated by a switching means, which has a recess in the activation position of the magnet, wherein the securing means or the rigid plate is adapted in its thickness to the size of the recess in the activation position of the magnet and between two recesses of two directly adjacent switching means of the at least one magnet-integrated Edge formwork element is guided in an adjustment between its locked position and its unlocked position.
