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.
L'invention concerne un coffrage pour colonnes cylindriques structur~ au moyen d'une pluralit~ de lames (2), de largeur r~duite, en bois plastifi~ ou en plastique rigide, assembl~es de fa×on ~ d~finir un corps tubulaire (1) et fix~es ~ l'aide d'une enveloppe ext~rieure (3) constitu~e d'une maille de fibre de verre ~ enroulement h~lico~dal, tandis que ce corps tubulaire (1) re×oit en son int~rieur un film auto-adh~sif (4). Ce coffrage peut ~ventuellement Útre muni d'un dispositif de raidissement qui maintient sa configuration cylindrique, qui se pr~sente soit sous la forme de collerettes (5) distribu~es de fa×on appropri~e, soit sous la forme d'un corps tubulaire (6) en polystyrne expans~ dispos~ entre le corps (1) et l'enveloppe ext~rieure (3). Le corps tubulaire (1) peut se pr~senter sous la forme d'une plaque unique (7) initialement plate, dont la largeur correspond au diamtre de la colonne ~ obtenir. Sur la face ext~rieure (10) de cette plaque (7), on pratique une pluralit~ de coupes longitudinales (9) qui d~finissent des zones d'affaiblissement (11) qui permettent la d~formation de ces plaques afin de les convertir en un ~l~ment cylindrique.
