摘要
A system for positioning and preloading a support beam by bending deformation, comprising a first anchoring unit (10) adapted to engage one end (8) of the beam (2), comprising: - a support base (12) adapted to bear on an abutment surface (6) external to the system. - a connection member (13) articulated on the support base in order to oscillate about an axis of articulation (Y) and - an attachment portion (15) adapted to engage the first end of the beam and secured on the connection member so that the longitudinal axis (X) of the beam, when engaged in the attachment portion, is spaced from the axis of articulation (Y) of the connection member so as to cause the connection member to oscillate about this axis of articulation as a result of a stress directed along the longitudinal axis of the beam. Thrust means (26) are disposed between the connection member and the end of the beam in order to space the beam (2) from the connection member (13) along the longitudinal axis (X), thus causing the axial stress and the resulting oscillation of the connection member so that the beam is bent and deformed in the direction of oscillation of the connection member (13) by the engagement of this first end (8) in the attachment portion (15).
