Title
(EN) A HELIOSTAT SUB-ASSEMBLY
(FR) SOUS-ENSEMBLE HÉLIOSTAT
Abstract
(EN)
The invention relates to a heliostat sub-assembly and to a method of forming such a sub-assembly. The method of mounting a concave mirror to a supporting structure of a heliostat includes the steps of bonding a plurality of risers at predetermined spaced intervals to a rear face of the mirror, each riser having a bonding pad and a stem extending from the bonding pad, and applying a predetermined concave curvature to the mirror by conforming the front face of the mirror with a convex forming jig or die. The supporting structure and curved mirror are then aligned, and the supporting structure is clinched to the stems of the risers when the curved mirror is conformed with the forming die. The riser stems may be coupled to the bonding pads via multi-axial joint assemblies to enable limited multi-pivotal movement of the stems relative to the bonding pads to facilitate alignment of faces of the stems with the faces of the ribs defined by webs, and relative expansion and contraction of the mirror and supporting structure, the overlap between the riser stems and the webs being sufficient to accommodate clinching with variations in curvature of the glass sheet.
(FR)
L'invention concerne un sous-ensemble héliostat et un procédé de formation d'un tel sous-ensemble. Le procédé de montage d'un miroir concave sur une structure de support d'un héliostat comprend les étapes consistant à lier une pluralité de colonnes montantes à intervalles espacés prédéfinis au niveau d'une face arrière du miroir, chaque colonne montante comportant un plot de liaison et une tige s'étendant à partir du plot de liaison, et à appliquer une courbure concave prédéfinie au miroir au moyen de la conformation de la face avant du miroir à l'aide d'un gabarit ou d'un moule de formage convexe. La structure de support et le miroir incurvé sont ensuite alignés, et la structure de support est accrochée aux tiges des colonnes montantes lorsque le miroir incurvé est conformé à l'aide du moule de formage. Les tiges des colonnes montantes peuvent être accouplées aux plots de liaison par l'intermédiaire d'ensembles joints multi-axiaux afin de permettre un mouvement multi-pivotant limité des tiges par rapport aux plots de liaison, en vue de faciliter l'alignement des faces des tiges aux faces des nervures définies par des âmes et la dilatation et la contraction relatives du miroir et de la structure de support, le chevauchement entre les tiges des colonnes montantes et les âmes étant suffisant afin d'adapter l'accrochage aux variations de courbure de la feuille en verre.
