Definitions

  • the invention further relates to a battery formwork with such a formwork and a further formwork element, a formwork space being provided between the formwork panel of the formwork and the further formwork element.
  • a recess formwork can be used to form an opening for a window, a 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. Links are formed on the outer circumference of the inner frame, which hold the frame sections of the recess formwork in an articulated manner. The links can be pivoted so that the recess formwork is reduced in size and so the outer formwork together with the recess formwork of the created concrete body can be peeled off. Spindles which can be lengthened or shortened are provided for pivoting the handlebars.
  • 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.
  • 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.
  • a further aim of the invention can be to improve the transfer of loads during concreting.
  • 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.
  • the sliding and tilting mechanism of the stripping device is actuated.
  • the shifting and tilting mechanism is set up to shift the frame element in the direction parallel to the main plane of the formwork panel and at the same time to tilt the frame element about the pivot axis running parallel to the main plane of the formwork panel.
  • the frame element cannot can only be moved along the inside of the panel, but also tilted away from the inside of the 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.
  • the frame element can be tilted away from the formwork when the concrete element is separated 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).
  • the frame 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.
  • 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 in it so as to be displaceable and pivotable, the longitudinal guide on one of Support bracket and bearing element and the guide element is provided on the other of the support bracket and bearing element.
  • the longitudinal guide is preferably formed on the support bracket and the guide element on the bearing element.
  • the reverse arrangement can also be provided.
  • the frame element 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 necessary.
  • the transition from the shuttering to the shuttering position can be jerky.
  • 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 parallel to the formwork panel are blocked.
  • the support bracket 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.
  • the recess formwork preferably has a securing element for securing the support bracket in the formwork position.
  • the secured state of the securing element the recess formwork is secured against being transferred from the formwork position to the stripping position.
  • the unlocked state of the securing element the transfer from the shutter position to the shutter position is released.
  • the concrete element can be poured 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.
  • the securing element can be connected to the bearing element via a releasable connection, in particular via a screw connection.
  • the formwork can be prepared by loosening the detachable connection.
  • the detachable connection is established to enable the concrete element to be poured with the recess.
  • the releasable connection of the securing element can therefore be made and released reversibly, ie without any loss of function, and preferably without tools.
  • the screw connection 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.
  • 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 favorable if the securing element has a holding plate on which the holding 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.
  • 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.
  • the retaining plate of the securing element has essentially the same shape and extension as the bearing plate of the bearing element, the retaining 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.
  • a magnetic connection can also be provided.
  • the securing element in a preferred embodiment has a first holding surface for contact with an outside of the support bracket facing away from the panel and / or a second holding surface for contact with an end face of the support bracket facing away from the frame element.
  • the second holding surface of the securing element is preferably designed as a wedge surface. This design causes a reliable securing of the frame element in the shuttering position in order to enable the precise formation of the recess in the concrete element.
  • the bearing element has at least one first wedge surface and the securing element has at least one second wedge surface, 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.
  • the first and second wedge surfaces are arranged at an angle 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 preferably diverge in the direction away from the inside of the formwork panel.
  • 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 contact surfaces for the second wedge surfaces of the securing element in order to facilitate the attachment of 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.
  • the bearing element has at least two, preferably four, bearing points for mounting two, preferably four, support brackets. At least one pair of bearing points is preferably provided for two support brackets, which protrude in opposite directions from the bearing element. Thus, two opposite boundaries of the recess of 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 bearing points 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 are attached in order to form two, three or four boundaries of a rectangular recess in the concrete element.
  • the bearing points each have at least one holding flange with a bearing opening.
  • the retaining flange is preferably arranged essentially perpendicular to the formwork panel.
  • the guide element, in particular the bolt, of the shifting and tilting mechanism is preferably mounted on the bearing opening. It is also favorable if the bolt is detachably attached to the bearing opening, in particular detachable without tools. The bolt can be secured to the bearing opening with a cotter pin.
  • the associated bracket can be detached from the bearing element in a simple manner if the corresponding bearing point is not to be occupied by a bracket for the current application.

  • the two preferably rectangular formwork panels are each pivotably connected at a first end region, in particular on one of their longitudinal sides. For this purpose, an articulated connection can be provided between the first end regions of the formwork panels.
  • Formwork panels can be transferred from a standing state, in which the formwork elements are preferably aligned essentially vertically, into a lying state, in which the formwork elements are preferably aligned essentially horizontally.
  • 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.
  • the recess formwork can be mounted on the panel.
  • the formwork is preferably used in a battery formwork which has a further formwork element, with a formwork space being provided between the formwork panel of the formwork and the further formwork element.
