Definitions

  • the invention relates to a form or formwork for producing columns made of concrete.
  • the object of the invention is to develop a formwork for columns made of concrete so that the elements can be removed after the completion of a column so that these elements can be used again.
  • a major advantage of the column formwork according to the invention is that the moldings used and also the strips used can be removed and reused after the completion of a column.
  • the molded parts are only secured against each other by the strips inside the outer sleeve-like element, so that after the concrete column is finished, the outer sleeve-like element is opened and then the strips and the various molded parts can be removed. Only the outer sleeve-like element is lost, ie this element cannot be used again will.
  • an inexpensive material such as cardboard or cardboard, is used as the flat material for the production of this element.
  • 1 is a concrete column, which has a rectangular cross section and is broken at its corners or edges, i.e. there has sloping surfaces 2.
  • the formwork 3 shown in section in FIG. 2 which consists of an outer sleeve-shaped or cylindrical element 4 as well as several molded parts 5 and 6 arranged inside this element 4, which one Enclose rectangular formwork interior 7 for the manufacture of column 1.
  • a plurality of molded parts 5 and 6 are also provided in succession in the longitudinal direction or in height.
  • the sleeve-like element 4 is made of a flat material, for example cardboard or cardboard, and forms the outer, closed skin that absorbs tensile forces and holds the formwork together.
  • the molded parts 5 and 6 are made of foamed plastic (polystyrene) and are designed such that that there is a circular outer cross-section for the formwork 3.
  • the axial length of the Formwork 3, which extends (length) perpendicular to the plane of the drawing in FIG. 2, can be chosen arbitrarily according to the respective application.
  • the interior formwork interior 7 has a rectangular cross-section, but can also have a different cross-sectional shape.
  • the molded parts 5 and 6 which are each provided twice and which alternately connect to each other in the circumferential direction of the sleeve-like element 4 (FIG. 2), each have a circular segment-like cross section in such a way that part of the circumferential line of this cross section has an arcuate outer surface 5 'or 6' and part of a tendon-like inner surface 5 '' and 6 '' is formed.
  • a longitudinal edge 5 '' 'and 6' '' is provided at the transition between the outer surface and the inner surface.
  • the fittings 5 and 6 are curved such that these outer surfaces complement one another to form a circular cylindrical surface which is enclosed by the sleeve 4.
  • each bar 8 thus forms, through its profile, which is composed of two isosceles triangular profile sections 9, which are connected to one another at a triangle tip, ie in the area of a transition 10, two substantially rectangular recesses 11.
  • Each bar 8 is for holding the molded parts 5 together and 6 in the area of a corner of the molding space 7 arranged in such a way that the strip 8 there forms a beveled corner of the molding space 7 with a longitudinal side 8 'opposite the transition 10 and is supported with the other longitudinal side 8''opposite the transition 10 against the inner surface of the sleeve-like element 4.
  • a longitudinal edge 5 ′′ ′′ or 6 ′′ ′′ of a molded part 5 or 6 is received by the recesses 11.
  • the moldings 5 and 6 are held in a form-fitting manner inside the sleeve-like element 4 by the strips 8, by the element 4 and by their support on these strips 8, without additional means being required for this.
  • the particular advantage of the formwork 3 is in particular that after the completion of the column 1, the moldings 5 and 6 and the strips 8 can be removed and used again. The molded parts 5 and 6 and the strips 8 are thus not lost.
  • strips 8 or the profile forming these strips can be used for formwork 3 with different shapes and sizes of molded parts 5 and 6.
  • the formwork 3 can be made with the required length.
