Definitions

  • the invention relates to a method for the selection of shuttering profiles, which are arranged for producing at least one formwork with a substantially closed inner peripheral edge for a polygonal, in particular rectangular, precast concrete element on a pallet form, the selection of the shuttering profiles to be positioned corresponding to the nominal values of their length, is determined in particular on the basis of a geometric data set for the concrete precast element to be produced.
  • 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 fitting elements when demoulding the precast concrete element, resulting in an enormous overall time delay, which is particularly disadvantageous when the precast concrete elements manufactured in a production line become.
  • the invention has the object to provide a method for the selection of Abschalprofilen, which allows avoiding the disadvantages described above, a quick shelling and Entschalen and is particularly suitable for use in automated production lines.
  • a further exemplary embodiment of the invention provides that the sum of the longitudinal extent of the shut-off profiles to be arranged behind one another is at most smaller by the value f than the length of the side of the formwork to be produced.
  • a method for producing at least one formwork for a polygonal, in particular rectangular concrete prefabricated element of several inventively selected Abschalprofilen on a pallet form a pallet circulating system to be specified, accordingly only substantially equally trained Abschalprofile with standard lengths to form a substantially closed inner peripheral edge are used the number of Abschalprofile used is greater than the number of sides of the produced polygonal precast concrete element.
  • the invention further relates to a formwork for a particular rectangular concrete finished component to be produced on a pallet form whose substantially closed inner peripheral edge is bounded by a plurality of elongated Abschalprofilen, wherein at least one side of the inner peripheral edge of the formwork is formed by at least two substantially equal trained Abschalprofilen with standard lengths 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 filled by means of so-called fitting elements according to the prior art. 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.
  • 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, a reinforcement station and a curing chamber of a production line go through in a method according to the invention.
  • this object is achieved in that the feed of the pallet shapes takes place synchronously 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.
  • 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.
  • a basic idea of the invention is thus to shift the pallet shapes synchronously, ie simultaneously, at least from the de-scaling station to the curing chamber, preferably at all stations of the production line.
  • the clock of Synchronous shift of the time of the power strokes at the individual stations and the transport time between the individual stations of the production line depend.
  • the synchronous feed of the pallet forms takes place at regular intervals, wherein the clock of the synchronous shift in response to a predetermined maximum time per 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, whereby a particularly high utilization of the production line can be achieved if the maximum time is less than 4 minutes, preferably at about 3.5 minutes.
  • the cycle time of the synchronous shift can also be shortened, it being provided according to a further embodiment of the invention that the cycle time of the synchronous shift between 3.5 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, but the synchronous feed of the pallet forms takes place after completion of the working cycle at the slowest station.
  • the synchronization shift can be triggered automatically, preferably by means of a system control, or manually.
  • 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 at least the same number of precast concrete elements can be produced with the method according to the invention in the same time as with the conventional methods.
  • the method according to the invention allows a tremendous reduction in personnel, whereby the total costs can be considerably 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.
  • Smaller distances between the series-laid Abschalprofilen 10 do not play a major role, but the distance between the individual Abschalprofilen should not be greater than 1.5 cm in order 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 the Abschalprofile 10 and is the inner peripheral edge U 1 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 I , while the Abschalvid 24 opposite sides of 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.
  • the laying of Abschalprofile 10 can be done entirely with a formwork robot 8, where it has been found to be particularly advantageous if only one formwork per pallet 21 is arranged, since then the center M of the pallet 21 as a reference point for the shuttering robot. 8 can serve.
  • a very short overall time required for the shelling of concrete precast element is achieved, whereby a total of a short cycle time for the synchronous shift and a particularly efficient automation of the pallet circulation system can be achieved.
  • Plant 1 shown comprises several stations, which are arranged such that the pallet molds 21, on which the precast concrete elements are produced, these stations in the sense of a production line in particular circulating through.
  • This production line comprises a de-scaling station 2, in the region of which a demolition cross-piece 3 is arranged. Subsequent to the de-scaling station 2, a shuttering removal station 4 follows, in which the shuttering profiles 10 are removed from the pallet mold 21. This is followed by the cleaning station 6, which is associated with a cleaning and ⁇ lungsvorraum 5.
  • the pallet molds 21 are conveyed to the formwork station 7.
  • the shells of concrete precast elements by means of a formwork robot 8, which fetches the Abschalprofile 10 from the formwork bearing 9 and positioned on the pallet mold 21 located in the formwork station 7.
  • the Abschalprofile 10 go through after removal of the pallet mold 21 in the formwork removal station 4, a transport and cleaning line 22 before being deposited in the formwork bearing 9.
  • the formwork station 7 is followed by a blind station 12, at which no work is carried out.
  • the concreting station 14 which is assigned to the concreting device 13, by means of which the concrete is introduced into the formwork 11.
  • the concreting station 14 is again followed by a blind station 12 and thereupon the reinforcement station 15, in which by means of a positioning device 16, the reinforcements prepared in the reinforcement preparation station 18 are introduced into the concrete element already concreted but not yet hardened.
  • the recovery station 15 is followed by the pick-up station 17 and possibly another blind station 12.
  • the pallet molds 21 are picked up by the pick-up station 17 or the subsequent blind station 12 and brought into the curing chamber 20, where the Cement ready element cures under supply of hot air. After setting of the concrete, the pallet mold 21 is transferred from the curing chamber 20 in the de-scaling station 2 and there begins a new round through the production line.
  • Fig. 4b the transport routes between the individual stations of the production line are shown in a synchronous shift.
  • the pallet molds 21 are moved within a minute from one station to the next, wherein the displacement takes place synchronously.
  • Fig. 4c are the individual work processes, which must be performed during a power stroke whose maximum production time is set in the illustrated embodiment with 3.5 minutes.
  • the shuttering profiles are removed on the shuttering removal station 4
  • the pallet molds 21 are cleaned in the cleaning station 6
  • the formwork 11 is produced on the formwork station 7 by the shuttering profiles 10
  • concreting the Prefabricated concrete element takes place in the concreting station 14 wherein any reworking can be carried out on the blind station 12, on the rebar station 15, the reinforcements are introduced, while on the pickup 17 any special reinforcements can be introduced.
  • the timing of the synchronous shift is composed of the maximum manufacturing time of 3.5 minutes and the transport time of 1 minute, i. the pallet molds 21 are moved every 4.5 minutes between the synchronously connected stations of the production line.
  • the pallet molds 21 used in this embodiment are about 8 m long and 3 m wide, with about 88 pallets in a layer through the production line.
  • a pallet occupancy of 11.25 m 2 which corresponds to a precast concrete element with 4.5 m Length and 2.5 m width, can be achieved with the inventive system 1, a production of about 1,000 m 2 per shift with a duration of 8 hours.
  • the effective production time during one shift is 7 hours, while the cleaning time takes 1 hour.
  • the number of personnel required for the monitoring of the plant can be reduced to up to 3 persons, while in plants according to the prior art, in which the feed of the pallet forms was not synchronized, sometimes up to 20 people were necessary ,
  • FIG. 5 to 7 shown further embodiments of inventive systems 1 differ from the embodiment according to Fig. 4a to 4c only by the local arrangement of the individual stations of the production line, wherein in the embodiment according to Fig. 5 the stacking device 19 is formed by a stacker crane.
  • FIG. 6 illustrated embodiment shows a system 1, with the addition of element ceilings and double walls can be made.
  • a dummy station 12 is arranged after the concreting station 14, which is associated with a turning device 23 with a turning frame and suction cups.
