Definitions

  • the invention relates to a method for producing at least one formwork for a polygonal, in particular rectangular, prefabricated concrete element on a pallet form a pallet circulation system of several Abschalprofilen for producing the at least one formwork with a substantially closed inner peripheral edge for a polygonal, in particular rectangular precast concrete element on a Pallet form are arranged, wherein only substantially equally trained Abschalprofile with standard lengths are used to form the substantially closed inner peripheral edge and the selection of Abschalprofile to be positioned according to the set values of their length, which is determined in particular on the basis of a geometric data set for the finished concrete element to be manufactured ,
  • these mating elements In addition to the enormous amount of time required for the manual production and positioning of the fitting elements, these mating elements also require a manual removal of the mating elements when demoulding the precast concrete element, which results in an enormous time delay, which is particularly disadvantageous when the precast concrete elements manufactured in a production line become.
  • the DE 103 04 622 B3 and the DE 101 16 230 C1 each show a method for erecting a formwork for precast concrete components, in which Abschalprofile are arranged one behind the other, and a formwork for a manufactured on a pallet form precast concrete element.
  • Abschalprofile are arranged one behind the other
  • a formwork for a manufactured on a pallet form precast concrete element is disclosed in each case by means of which the formwork elements can be arranged one behind the other without a gap.
  • the US 3,730,657 A shows a device for pressing not yet cured concrete, which also serves as formwork.
  • the EP 1 273 407 A1 shows a Magnetsetzroboter for spatially positioned settling and / or receiving magnets for the arrangement of formwork in the manufacture of precast concrete components, wherein the Magnetsetzroboter can simultaneously accommodate a plurality of magnets.
  • the invention has the object to provide a method for producing a formwork of Abschalprofilen according to the teaching of claim 1, which allows avoiding the disadvantages described above, a quick shelling and Entschalen and in particular for use in automated production lines is suitable.
  • the selection of the Abschalprofle takes place such that the sum of the longitudinal extent of the at least two sequentially arranged Abschalprofrate is smaller than the length of the side of the formwork to be produced.
  • the invention provides that the sum of the longitudinal extent of the Abschalprofile to be arranged behind the other at most by the value f is smaller than the length of the side of the formwork to be produced.
  • the invention further relates to a formwork for a manufactured on a pallet form, in particular rectangular concrete prefabricated element according to the teaching of claim 5, whose substantially closed inner peripheral edge of several elongated Abschalprofilen is limited, wherein at least one side of the inner peripheral edge of the formwork of at least two substantially equal trained Abschalprofilen with standard lengths is formed, which are arranged one behind the other in the longitudinal direction.
  • Abschalprofilen In known formwork as many sides of the finished concrete element to be manufactured are formed by Abschalprofilen standardized length. Since the standardized lengths of Abschalprofile in the fewest cases correspond to the side lengths of the concrete precast element to be produced, remaining gaps in the peripheral edge of the shells are achieved by means of so-called fitting elements according to the prior art filled. These mating elements can be made of styrofoam or wooden parts, for example, and are usually shortened and fitted manually to the required length during the production of the formwork.
  • one side of the formwork is formed by at least two series-laid shuttering profiles of standardized length, it is possible to dispense with the use of fitting elements as a whole, which results in an enormous saving of time.
  • An embodiment of the invention further relates to the use of a plant for the production of precast concrete elements with a production line, in which the production of the components takes place on pallet forms, which successively at least one de-scaling station, a cleaning station, a particular automatic formwork station, a concreting station, a reinforcement station and a curing chamber a production line undergo in a method according to an embodiment.
  • Such systems are used to produce flat concrete elements, in particular ceiling and wall elements.
  • the production of concrete elements takes place on pallet forms, also called production pallets, which successively pass through several stations of a production line.
  • the precast concrete element is de-energized and the Sheathing profiles removed from the pallet form.
  • the cleaning of the pallet forms before they are equipped at the Schalstation with new formwork.
  • the pallet shape is fed to the curing chamber, in which the setting of the concrete takes place.
  • the arrangement of buffer stations at which the pallet form is taken out of circulation is necessary due to the different duration of the work cycles at the individual stations, that is, after stations with a shorter working cycle, such as the Entschaluhgsstation, Buffer zones are provided in which the pallet shapes can be parked until the subsequent station in the production line is free.
  • This object is achieved by synchronizing the feeding of the pallet shapes from the de-scaling station to the curing chamber. Characterized in that the feed takes place according to the invention at the same time, can be dispensed with the arrangement of buffer stations entirely and production bottlenecks can be avoided.
  • a further embodiment of the invention provides that in the course of the production line, one or more blind station (s) on which (no) operations take place are arranged, whereby attempts of the applicant have shown that an arrangement of a blind station between the Cleaning and formwork station and / or the formwork and concreting station is particularly advantageous for a smooth passage of the pallet shape through the production line.
  • the blind stations serve to bridge longer distances between two processing stations. This is necessary because, as a result of the synchronous feed of all pallet shapes, a longer transport time between two stations due to a longer distance would shorten the time available for coping with the subsequent work cycle.
  • the feed of the pallet shapes takes place synchronously at all stations of the production line, wherein it has turned out to be advantageous if the pallet forms pass through the production line all around.
  • One aspect of the invention is therefore to synchronously, i.e. at all stages of the production line, the pallet molds at least from the de-scaling station to the curing chamber. to move at the same time.
  • the clock of the synchronous shift will depend on the time of the power strokes at the individual stations and the transport time between the individual stations of the production line.
  • the synchronous feed of the pallet forms takes place at regular time intervals, wherein the clock of the synchronous shift in dependence of a predetermined maximum time per power stroke at the individual stations of the production line and the transport time of the pallet forms between the individual stations of the production line is fixed.
  • the timing of the synchronous shift which corresponds to the time between the individual feeds, is composed of the time of the power strokes and the transport time between the individual stations.
  • the maximum time per power cycle at the individual stations of the production line is less than 6 minutes, preferably less than 4.5 minutes, with a particularly high utilization of Production line can be achieved when the maximum time is less than 4 minutes, preferably about 3.5 minutes.
  • the cycle time of the synchronous shift can also shorten, which is provided according to a further embodiment of the invention that the cycle time of the synchronous shift between , 5 and 5.5 minutes, preferably about 4.5 minutes.
  • Another embodiment of the invention provides that the synchronous feed of the pallet forms takes place at irregular time intervals, wherein the triggering of the synchronous shift takes place in dependence on the time of the longest working cycle of the individual stations of the production line.
  • this embodiment is based on the time required for the power stroke at the slowest station. In contrast to the above-described embodiment, however, no maximum time is determined or predetermined for this time-consuming station, but takes place, the synchronous feed the pallet shapes after completion of the power stroke at the slowest station.
  • the synchronization shift can be triggered automatically, preferably by means of a system control, or manually.
  • the production of precast concrete element follows a completely new logic. While according to the state of the art as many precast concrete elements as possible have been produced on a production pallet, according to the invention only one precast concrete element per pallet form is produced. The poorer utilization of the individual pallet shapes brings with it the advantage of a fixed maximum working time per working cycle, which allows a consistent automation of the production line, so that ultimately the process can produce at least as many prefabricated concrete elements in the same time as with the conventional methods.
  • the method according to the invention allows a tremendous reduction in personnel, which considerably increases the overall costs can be reduced.
  • the maximum time per stroke allows a predictable turnaround time for a pallet shape through the production line, thereby avoiding production bottlenecks.
  • Fig. 1 illustrated embodiment of a formwork 11 according to the invention three sides of the peripheral edge U a of Abschalprofilen 10 are formed with a standardized length.
  • the fourth side of the formwork 11 with the side length L is in contrast to the embodiments according to Fig. 5a to 5c not formed by a projecting Abschalprofil 10 but rather by two set in series Abschalprofilen 10.
  • a corresponding grid of different standard lengths for formwork profiles 10 almost all required side lengths L of a precast concrete element to be produced can be switched exclusively with shuttering profiles 10 of standardized length using this method. It play smaller distances between the series Shuttering profiles 10 no major role, however, the distance between the individual Abschalprofilen should not be greater than 1.5 cm to avoid spillage of the concrete.
  • Fig. 2a to 2c are further embodiments of formwork 11, which are arranged on a pallet 21, shown.
  • at least three of the formwork 11 forming Abschalprofile 10 project beyond the outer peripheral edge U a , in each case to the section A.
  • the outer peripheral edge U a is defined by the Abschal vom 24 opposite longitudinal sides of Abschalprofile 10 and is the inner peripheral edge U l geometrically similar.
  • the peripheral edge of the formwork 11 is formed by the Abschalprofilen 10, the Abschalvid 24 of Abschalprofile 10 forming the inner peripheral edge U l , while the Abschalvid 24 opposite sides of the Abschalprofile 10 are part of the outer peripheral edge U A.
  • Fig. 2a stand all Abschalprofile 10 over the outer peripheral edge U A , while in the Fig. 2b and 2c only three Abschalprofile 10 protrude beyond the outer peripheral edge U A.
  • Abschalprofile 10 The advantage of this arrangement of Abschalprofile 10 is that it can be dispensed with the use of fitting elements entirely, since the inner peripheral edge U l is limited to the whole of Abschalprofilen 10 standardized length.
