Definitions

  • Formworks for pillars are known e.g. from DE29609259, using two segments of a plastic tube, which was sliced and divided lengthways along the tube axis before.
  • the formwork is mounted by positioning both tube segments against each other thus forming the outer shell of the formwork in which an inner auxiliary formwork element can be inserted.
  • Both tube segments are connected to each other by way of angled elements and bolts or the like. These angled elements have to be previously attached to both tube halves e.g. by gluing.
  • a flat iron band is attached to one of the tube halves overlapping the gap between both tube segments.
  • iron ribbons are secured around the formworks forcing the segments together.
  • a conventional outer formwork is additionally provided with a thin layer serving as inner auxiliary formwork element in order to achieve a specific surface finish.
  • US5098059 describes a foam piece surrounded by a plastic layer. This plastic layer allows the foam piece to be easily removed from hardened concrete to be reused. However, in all cases no further details relating to the positioning, assembling and fixing of outer formworks for pillars of different shape are given.
  • this invention is very versatile because it permits the easy extension of the formwork because of the elements (5) from where we can get rectangular or square sections when joined together to having always the same measure. That means that there is allways a standard element and the elements can be used in rectangular or square pillars.
  • the elements are connected by male and female coupling means which are formed integrally by the ends of the standard elements and consist of male (4) and female (3) coupling means being removably connectable to each other.
  • male and female coupling means which are formed integrally by the ends of the standard elements and consist of male (4) and female (3) coupling means being removably connectable to each other.
  • the formwork must be made one for each diameter because the parts are fixed and can not be extended.
  • the formwork according to the invention is composed by two formworks (one exterior (5-4-3)- the real formwork and one interior (8) -a thin piece of plastic -which we are going to call a wrapper).
  • This interior wrapper is very important because it has the specific functions of isolating the exterior formwork from the contact with concrete and of giving the surface pillar the final polish appearance. This final surface permits direct painting.
  • This wrapper (8) is, of course, very cheap and is used only once.
  • the exterior formwork is provided with "ribs" (11) which give the formwork a better resistance and allow the fixing of vertical irons (7) which are directed to small mortar (10) previously embedded in the floor concrete. This also allows the formwork do not move while the concrete is dropped in.
  • the already above mentioned forces of compression mostly in the large pillars, will be annulled by 3 or 4 metallic belts (12) disposed along the formwork and against the vertical irons (7) which provide the necessary resistance.
  • the Fig 2 represents a circular pillar formwork. To change the measures we need other elements (5) in different measures. This formwork is also formed by an interior wrapper (8).
  • the Fig 3 represents a pillar formwork for a square section. If we want to transform it for a rectangular section we only need to add elements (5) in two parallel walls.
  • Fig. 5 represents a perspective of a finished pillar with the wrapper (8).
  • Fig 6 intends to be a simple formwork for special cases when we need to make simultaneously the beam and the pillar. It's made by angled elements (13) which are closed by some vertical irons passing into rings to allow the horizontal dismount.

  1. Schalung zum Giessen von Betonsäulen, die eine Alternative zu Schalungen aus Eisen oder Holz darstellt, bestehend aus mehreren formgebenden Standardelementen (5) welche zusammengebaut ein erweiterbares Volumen quadratischen, rechteckigen oder kreisförmigen Querschnitts formen, das von Beton eingenommen werden kann, wobei die Standardelemente (5) über Verbindungsmittel (3,4), die an den jeweils linken und rechten seitlichen Endbereichen besagter Elemente positioniert sind, miteinander verbunden werden, besagte Elemente durch Eisenstäbe (7), die die Schalung in senkrechter Stellung halten, verstärkbar sind, eine separate Plastikplane (8), die in die zusammengebaute Schalung eingelegt wird, die Fügestellen zwischen den einzelnen Elementen bedeckt, die Innenflächen der formgebenden Elemente (5) vor dem Kontakt mit Beton schützt und dem ausgehärteten Beton ein poliertes Aussehen gibt, wobei die besagte Schalung dadurch gekennzeichnet ist, dass die besagten Verbindungsmittel integral von den Endbereichen der Standardelemente gebildet werden und aus männlichen (4) und weiblichen (3) Verbindungsmitteln bestehen, die lösbar miteinander verbindbar sind.
  2. Schalung entsprechend Anspruch 1, wobei besagte Standardelemente (5) aus Kunststoff hergestellt sind.
  3. Schalung entsprechend jedem vorangehenden Anspruch, wobei die Plastikplane aus kostengünstig ersetzbarer Kunststoffolie zur einmaligen Benutzung pro Gussvorgang besteht.
  4. Schalung entsprechend jedem vorangehenden Anspruch, wobei besagte Eisenstäbe (7) in einer zuvor im Betonboden eingebetteten Mörtel-Basis gesichert sind.
  5. Schalung entsprechend jedem vorangehenden Anspruch, wobei besagte Standardelemente (5) gegen Druckkräfte durch 3 oder 4 metallische Gürtel (12) gestützt werden, die entlang der Höhe der Schalung angebracht sind.
