Definitions

  • the invention relates to a method for the formwork of prefabricated reinforced concrete parts, whereby on a basic formwork, in particular a pallet, longitudinal and head formwork and optionally at least one further formwork part for forming fitting pieces, recesses, undercuts etc. are fastened and cleaned and removed after the formwork of the reinforced concrete part be reused.
  • a basic formwork is usually used to manufacture prefabricated reinforced concrete parts with essentially standardized width.
  • B. uses a base plate or a pallet, the two lateral longitudinal formwork are assigned.
  • one of the longitudinal formworks is designed to be stationary, while the other can be moved away or folded down in order to enable the formwork to be removed.
  • two stationary longitudinal formworks can also be used.
  • transverse head formwork is inserted and fastened at the desired positions on the longitudinal formwork.
  • prefabricated reinforced concrete parts with relatively simple shapes can be produced, the height of which is predetermined by the height of the longitudinal and top formwork.
  • prefabricated parts with dimensions that differ from the standard width or height, as well as inclined parts, fitting pieces, recesses, undercuts, etc. must be manually inserted into the basic formwork with an additional suitable one
  • Formwork material to be switched off According to DE 21 35 049 AI and DE 41 29 368 AI, at least one additional formwork part is used for this purpose, which can be a plate or a profile made of wood, styrofoam, plastic, steel or the like appropriate places on the pallet or on the inside of the longitudinal or head formwork. Either an adhesive, double-adhesive adhesive strips, vacuum holder, magnet holder or spreader bars, etc. are used for fastening.
  • the formwork and the other parts of the formwork should be reusable after stripping. For this purpose, they are cleaned after stripping and stored in a magazine. Since the formwork and, in particular, the formwork parts are usually available in different, predetermined lengths and, moreover, often have different miter bevels, it is difficult to achieve a useful magazine. In addition, the reuse is different
  • robots are used in the manufacture reinforced concrete parts for formwork and formwork.
  • the robots first place the fastening elements, usually holding magnets, on the pallet or the formwork in a length that essentially corresponds to the spacing of the additional formwork parts used.
  • the formwork parts are then placed on the holding magnets and fixed in the formwork in this way.
  • the formwork parts are often made of U-shaped profile sheets in lengths of 500 mm, 1000 mm, 1500 mm, 2000 mm and 2500 mm. If a combination of several corresponding formwork parts is not sufficient to form the length of the desired formwork profile, the missing length must be added manually by an operator, which is usually done with the aid of a styrofoam profile. Even inclined parts and recesses are often switched off manually using styrofoam profiles, which makes the formation of the formwork overall time-consuming and cost-intensive.
  • the invention has for its object to provide a method for formwork of precast reinforced concrete, with which the aforementioned disadvantages are avoided and in which the formwork and / or the formwork parts are effectively reusable after stripping.
  • Adding the formwork material used to the endless strand has the advantage that there is no need for magazines according to fixed lengths.
  • the desired length can be cut off from the strand in one piece shortly or immediately before installation on the pallet with high accuracy. If necessary, the cutting off of the strand can also be carried out as a miter cut with any angle. It has proven useful to carry out the computer-controlled cutting of the formwork and / or the formwork part of the desired length from the strand, so that the formwork and / or the formwork part are produced individually for each formwork job with high accuracy and at the right time. However, manual cutting to length is also conceivable.
  • the formwork parts are preferably formed from a profile made of plastic, in particular foamed plastic, but profiles made of molding sand mixed with binder, metal, wood or a combination material can also be used.
  • the formwork and / or the formwork parts are cleaned and re-attached to the rear end of the long or endless strand, which can preferably be done by gluing, welding or in any other suitable manner.
  • the strand can also be produced using an extruder.
  • the formwork or formwork parts already used then do not have to be glued or welded or snapped onto the rear end of the strand, but rather are fed back into the extruder, where appropriate they are granulated beforehand.
  • the miter cuts are usually first cut after cleaning, so that the formwork part can be butted at the rear end of the strand. If two consecutive formwork parts have miter cuts of the same type, the two formwork parts at the rear end of the strand can also be joined together without capping, if necessary.
  • the cut pieces can be obtained as waste at most, the resulting amount of waste is kept very small.
  • plastic has the further advantage that the formwork parts have a very low weight, so that the parts can either be handled manually in a simple manner or the formwork parts receiving robot can be carried out relatively easily.
  • the method according to the invention can also be carried out manually by an operator, it has proven useful for reasons of economy to use robots.
  • the robot grips the formwork or the formwork parts and first feeds them to an intermediate station in which fasteners are applied.
  • fasteners can be, for example, hot melt glue guns for applying glue.
  • the robot can then place them on the pallet and fasten them at a predetermined location without removing the formwork or the formwork parts. In this way, only a small number of robot movements are necessary, so that the shuttering can take place very quickly.
  • the side of the shuttering or the shuttering parts forming the shuttering surface can be configured in any way (right-angled or oblique, smooth or profiled) without the advantageous possible uses of the method according to the invention being restricted.
  • the formwork and / or the formwork part are temporarily stored in a buffer station after being cut off from the strand.
  • the formwork or formwork parts are created in their required length and stored in the order in which they are installed in the formwork in the buffer station.
  • the formwork 10 shown in the figure has a base plate in the form of a pallet 11, on one long side of which a longitudinal formwork 12 is fastened. A similar longitudinal formwork is provided on the other long side, but is omitted for reasons of clarity.
  • the individual steps are defined by triangular formwork parts 13, which are extruded as hollow profiles and have been cut to an exact length from an endless profile strand. This ensures that all stairs

Abstract

L'invention concerne un procédé de coffrage d'éléments unifiés en béton armé. Il est prévu de fixer sur un coffrage de base, notamment une palette (11), des éléments de coffrage longitudinaux et des éléments de coffrage de tête (12) et/ou au moins une autre pièce de coffrage (13), afin de former sur la palette (11) ou sur les éléments de coffrage, des évidements, des contre-dépouilles, etc. Les éléments et la pièce de coffrage (12, 13) sont nettoyés après décoffrage de l'élément unifié en béton armé et sont réutilisés. Afin d'améliorer leur réutilisation, il est prévu de sortir par découpage les éléments et/ou la pièce de coffrage (12, 13) d'un brin très long ou continu au profilage approprié et de les replacer après nettoyage à l'extrémité arrière dudit brin. Ce raccordement peut s'effectuer de préférence par collage ou soudage ou par enclenchement. Ce brin peut néanmoins être obtenu par extrusion et la pièce de coffrage peut être reformée à l'extrémité arrière du brin, le matériau de coffrage étant réacheminé jusqu'à l'extrudeuse après utilisation.
