Definitions

  • the present invention relates to a form work that has been specifically designed to obtain columns or cylindrical pillars.
  • the object of the invention is to achieve a structurally simple form work and consequently inexpensive, which also uses minimum space when is not in used; i.e., in storage or transport situation, which also implies low costs
  • the invention is in the field of construction.
  • semi-cylindrical, modular metal sheets are used to build cylindrical columns, which are engaged one to the other laterally and longitudinally to form a cylindrical body of a diameter and length that depend on the column to build.
  • This approach has the main advantage of that the form work is recoverable or reusable, but on the other hand is extremely heavy and needs a lot of labor not only for assembly, but also for disassembly and cleaning.
  • this modular form work is subjected to knocks that deform and negatively affect the finish of the column to obtain.
  • the proposed form work comprises a tubular, inextensible, flexible body made, for example, of vegetable, mineral or woven-synthetic materials that can be compacted like laminated paper or polymer. Besides, it can be stored and transported modularly compacted or wound to form a roll, which allows storing form works for columns of great diameter and height in a minimum volumetric space when are not in used. This takes up relatively less space than the space modular metal sheet systems take up, and fairly less space than the space rigid tube systems take up.
  • the tubular body of the invention also comprises a pair of rigid cylindrical rings that are coupled to the ends of the tubular body so that the ends take a perfectly cylindrical form. Cramps or any other suitable elements are used to engage the rings.
  • the invention also comprises a series of at least two extensible poles that can be engaged in their ends to the engagement or coupling elements of the above-mentioned rings.
  • the complete tubular body takes a cylindrical form that remains perfectly stable during the process of filling it with concrete.
  • the form work disclosed comprises a tubular body (1) made of a flexible, inextensible, material, like any woven material that allows achieving a perfect stability not only longitudinally, but also radially.
  • a tubular body (1) made of a flexible, inextensible, material, like any woven material that allows achieving a perfect stability not only longitudinally, but also radially.
  • raffia, paper sheets or polymers can be used.
  • said tubular body (1) can be compacted over itself modularly or can be wound forming a roll (2) to minimize the space used as it is shown in Figure 1 .
  • the width of the strip the tubular body (1) forms must be adequate to the diameter of the column to build.
  • tubular bodies of different sizes for different uses will be provided.
  • the length of the strip must be defined according to the height of the column to build, otherwise roll (2) can have a defined length and portions of different sizes can be cut from it according to the form work or column to build.
  • a pair of rigid, cylindrical rings (3, 3') is coupled to the ends of the tubular body (1), and particularly to a segment for a particular form work or column, as it is shown in Figure 3 .
  • These rings can be made of hard plastic or of any other appropriate material, and can be fixed to the tubular body (1) by means of cramps (4) or the like.
  • Rings (3, 3') have engagement or coupling elements (5) in their ends, which are used in the assembly position of the tubular body (1) to provide support for the ends of the extensible poles.
  • These poles are telescopic to adapt them to any column or form work height. They also have tightening and blocking means (7) that allow tightening the tubular body (1) by means of a determine separation between the two rings (3, 3'), as it is shown in Figure 2 in order for the complete tubular form to adopt a perfectly cylindrical form.
  • said extensible poles (6) are also recoverable and reusable.
  • the compact tubular body (1) can comprise an outer covering sheet, not shown in the drawings, depending on particular needs of each case, and specifically depending on the finish required for the column to build. It can be made of any appropriate material that allows obtaining a perfectly smooth surface or any other type of finish desired, for example imitation of wood streaks, in the column to build.
