SI2236699T1 - Formwork for prismatic columns - Google Patents

Abstract

Based on the conventional structure of formwork comprising an externally cylindrical tubular core (1), which, within, defines a prismatic housing (2), with a leaktight lining (3), said core being housed inside a surround (4) provided with hinging regions so that the formwork can be folded up when stored or transported, the features of the invention focus on the fact that the inner surround extends, with respect to the upper and also the lower end wall of the formwork, in the form of as many fins (6) as faces have been provided for the column or pillar, between which, when the formwork is assembled, an annular, laminar body (7), obtained from cardboard, plastic, wood or another material of suitable stiffness, externally encloses same, the internal dimensions whereof will be adapted to the dimensions of said column, and the thickness or external dimensions whereof will be sufficient to constitute a formwork-stabilizing element, for which purpose provision has been made for said fins (6) to be able to fold and to attach to the surface of the annular body (7).

Claims (3)

Formwork for prismatic columns Patent claims CLAIMS 1. Prismatic columns comprising a tubular core (1) within which a prismatic housing (2) is defined, wherein the core (1) is cylindrical outwardly made of cylindrical segments from a heat-shaped product or other similar light material, with a waterproof inner liner (3), wherein said core is located and is stabilized in the surrounding cavity (4) made of solid material and has folding regions (5) corresponding to the edges or cones of the prismatic column so that the panel can be folded along said edges or cones, in order to reduce the need for space during storage or transport, wherein the annular body (7) further has the abovementioned annular body, characterized in that said annular body (7) is a laminated annular body whose geometry corresponds to a section of said pillar (6) in such a way that the inner lining (3) extends beyond the lower part and through the lower part (6) whereby said annular, laminated body (7) is made of cardboard, plastic or wood or from another material of suitable rigidity, the internal dimensions of which are suitable for the purpose of said folding parts (6) for the dimensions of said column to be manufactured, its thickness or outer dimensions are sufficient to, after folding and attaching said folding parts (6) to the surface of said circular body (7), an element for stabilizing the cladding, thereby enabling the stabilization of the cladding. 2. Prismatic columns according to claim 1, characterized in that the annular body (7) has on its surface markings (8), for determining the position of the verticals defining the edges of the column, relative to the position of the panel. 3. Prismatic columns according to claim 1, characterized in that the annular body (7) is further divided into two parts (7 ') and (7 ") in the form L, which are mutually assembled by any conventional means at their edges and along its length, it allows the creation of frames of different sizes, adapted to multiple sections of panels or the like.
