Embodiment Construction

[0027] With reference to the drawings and more specifically to FIG. 1 , the formwork of the invention is constructed in its simplest embodiment as having an annular body ( 1 ) made of a plurality of rigid laminate plates ( 2 ), which Plasticized wood can be used as mentioned above or manufactured from hard plastic; they can be straight, in which case their width will be minimal in order to get good circumferential alignment when they are all bonded to each other, but they can also It can have a certain curvature according to the pillar to be obtained. The annular body (1) is suitably stabilized by means of a fiberglass mesh (3) rolled up in a helical shape on its outside and is also perfectly sealed by a self-adhesive inner film (4) which is continuously Cover the entire inner surface of the annulus (1).

[0028] A formwork constructed in this way is perfectly suitable for obtaining a cylindrical column with a diameter according to the formwork; the formwork, while being holl...

Abstract

Said formwork consists of a plurality of narrow laminae (2) made of plastified wood or rigid plastic, which are joined to form a tubular body (1) and are fixed with the aid of an outer envelope (3) consisting of a helicoidally wound glassfiber mesh while the inside of said tubular body (1) receives a self-adhesive film (4). Optionally, the formwork may be provided with stiffeners to preserve its cylindrical configuration, said stiffeners being adequately distributed collars (5) or a tubular body (6) made of stretched polystyrene that is placed between the body (1) and the outer envelope (3). The tubular body (1) can be a single plate (7) that is initially flat and whose width matches the diameter of the desired column. Said plate (7) has a plurality of longitudinal cuts (9) on the outer face thereof, which define weakening areas (11) enabling its deformation for the purpose of forming a cylindrical element.

Description

technical field [0001] The invention relates to a new formwork for obtaining cylindrical pillars, which is specially intended as a disposable or disposable element and is especially suitable for obtaining pillars made of reinforced concrete. [0002] The object of the invention is to obtain the best results by using a formwork with a simple and thus economical structure, with the highest dimensional and shape precision and with the best finishing of the columns to be obtained Spend. Background technique [0003] In order to construct a column, for example of reinforced concrete, a form or formwork is required to provide the column with defined configuration and dimensions; said formwork must fulfill two distinct but complementary properties: it must ensure that the column has The finish is perfect, and its cost is low enough to make it profitable for the builder, especially when considering that it is a one-off formwork. [0004] In this sense, it is worth mentioning the S...
