Title
(EN) A BEAM
(FR) POUTRE
Abstract
(EN) A beam comprises a pair of aluminium extrusions (10, 12) each having a web (14, 16) and a pair of spaced apart abutments (18, 20, 22, 24) extending substantially over the entire length of the web. The two webs (14, 16) are maintained in spaced parallel relationship by a plurality of sets of spacer plates (34, 36) and connecting bolts (38); rotation of a bolt (38) between an associated pair of spacer plates (34, 36) causing the plates to move away from one another into clamping engagement with corresponding facing abutments (18, 20, 22, 24) on the webs (14, 16) and apply tensile loading to those parts of the webs intermediate the abutments.
(FR) Une poutre comprend une paire de profilés en aluminium (10, 12), chacun desquels possède une âme (14, 16) et une paire d'appuis séparés par un espace (18, 20, 22, 24) et s'étendant essentiellement sur toute la longueur de l'âme. Les deux âmes (14, 16) sont maintenues espacées et parallèles par de multiples jeux de plaques d'espacement (34, 36) et des boulons de liaison (38); la rotation d'un boulon (38) entre une paire associée de plaques d'espacement (34, 36) permet d'éloigner les plaques l'une de l'autre pour qu'elles se serrent contre les faces d'appui correspondantes (18, 20, 22, 24) prévues sur les âmes (14, 16) et appliquent une charge de traction aux parties des âmes qui sont intermédiaires aux appuis.
