Reinforced concrete panel for the manufacture of
aboveground circular tanks, of the type comprising a
wall (1) fitted with a number of horizontal stiffening
ribs (3) which contain holes for the passage of
pre-stressing cables, wherein the said wall is flat and the
said holes are arc-shaped, and a method of manufacture
of said panels comprising the following stages:
- insertion of a flexible tubular element (11), of the
same length as an arc which presents a radius equal to
the radius of the tank and a chord equal to the width
of the panel, into a mould with mobile sides (8, 9), on
a pair of pegs (10) fitted to the sides at the
horizontal ribs of the panel; approach of the mobile
sides until the mould closes, so that the said flexible
tubular element takes on the arc shape required;
installation of reinforcement and laying of concrete;
concrete shaving; curing and removal of finished
product.
Panneau en béton armé pour la fabrication de réservoirs circulaires hors sol, de type comprenant une paroi (1) munie d'un certain nombre de raidisseurs horizontaux (3) dans lesquels ont été ménagés des trous pour le passage de câbles de précontrainte, ladite paroi étant plate et lesdits trous étant en forme d'arc. Est également l'objet de l'invention une méthode de fabrication desdits panneaux comprenant les étapes ci-après : insertion d'un élément tubulaire flexible (11) de la même longueur qu'un arc de rayon égal au rayon du réservoir, et de corde égale à la largeur du panneau, dans un moule avec parois mobiles (8, 9), sur une paire de piquets (10) fixés sur les côtés des nervures horizontales du panneau; approche des parois mobiles jusqu'à ce que le moule soit fermé, de sorte que ledit élément tubulaire flexible prenne la forme arquée requise; installation de l'armature et coulage du béton, arasage du béton, cure et enlèvement du produit fini
