A wall bracing system (10,110) that uses a beam (20) capable of bending to conform to a partially-buckled masonry wall (12) that has buckled inward from external forces, such as hydrostatic pressures to which basement walls are typically exposed. The bracing beam (20) is sufficiently flexible to conform to the partially-buckled wall (12), enabling the bracing system (10,110) to apply a relatively uniform pressure against the wall (12) to prevent further inward movement. One end of the beam (20) is secured to the basement floor (14) adjacent the wall (12), generally not more than the distance the wall (12) has bowed inward, i.e., the horizontal displacement of the primary fracture point (42) of the wall (12). The upper end of the beam (20) is held in place with a bracket system (24) secured to one or more overhead floor joists. The bracket system (24) applies a force against the upper end of the beam (20) toward the wall (12). Sufficient pressure is applied against the beam (20) so that at least the upper end of the beam (20) contacts and conforms to the buckled portion of the wall (12). As a result, the beam (20) is prestressed when installed, making positive contact with at least the portion of the wall (12) above its primary fracture point (42). Once installed, the prestressed beam (20) moves with the seasonal movement of the wall (12) as temperature and moisture changes occur, while preventing further buckling of the wall (12).
L'invention concerne un système de rétention de murs (10, 110) qui utilise une poutre (20) capable de fléchir pour épouser un mur de pierre (12) qui a fléchi partiellement vers l'intérieur sous l'effet de forces externes telles que des pressions hydrostatiques auxquelles sont généralement soumis les murs de fondation. La poutre de rétention (20) est suffisamment souple pour épouser le mur partiellement fléchi (12) et permettre au système de rétention (10, 110) d'appliquer au mur (12) une pression relativement uniforme pour prévenir tout mouvement ultérieur vers l'intérieur. Une extrémité de la poutre (20) est solidarisée au plancher de fondation (14) adjacent au mur (12), en général pas plus qu'à la distance à laquelle le mur (12) a fléchi vers l'intérieur, c'est-à-dire à la distance du déplacement horizontal depuis le point de fracture primaire (42) du mur (12). L'extrémité supérieure de la poutre (20) est retenue en place par un système de fixation (24) solidarisé à une ou plusieurs solives du plancher supérieur.
