Abstract

La présente invention porte sur un dispositif de renforcement de force interne pour une structure de pilier, lequel dispositif comprend : une pluralité de plaques de renfort internes qui enveloppent le tour d'une surface périphérique du pilier ; au moins une paire de plaques de renfort externes qui sont couplées entre elles de façon à envelopper le tour d'une paroi externe du pilier de façon à être séparées vis-à-vis des plaques de renfort internes ; et un élément de commande de pression qui est disposé sur la plaque de renfort externe pour appliquer une pression ou libérer une pression sur la plaque de renfort interne vers ou à partir du côté de pilier. De cette manière, les performances de renforcement de force interne de la structure de pilier sont améliorées, et, en même temps, l'aspect pratique vis-à-vis de la construction, de la maintenance et de la réparation, ainsi que du démontage, est significativement amélioré.
