Abstract

Un dispositif pour supprimer une vibration verticale, qui absorbe la vibration en amplifiant l'ampleur du déplacement d'un corps de structure. Dans le dispositif, le nombre de pièces est réduit à un minimum et l'on améliore la simplicité de la construction (en construction sur site), la capacité de maintenance et l'efficacité économique. De plus, le dispositif peut parvenir à une meilleure suppression des vibrations. Le dispositif de suppression de la vibration verticale est composé d'une section de liaison (2) et d'un élément étiré (1). La section de liaison (2) possède des premières tiges de structure (21) fixées par pivotement à la base ou près d'une section de projection (W2) d'un corps de structure (W), des deuxièmes tiges de structure (22) fixées par pivotement aux sections de tête des premières tiges de structure (21), des troisièmes tiges de structure (23) fixées par pivotement à la section de tête de la section de projection (W2) et des quatrièmes tiges de structure (24) dont une extrémité de chaque est fixée par pivotement à une section de tête de chacune des troisièmes tiges de structure (23) et l'autre extrémité est fixée par pivotement à la section de tête de chacune des premières tiges de structure (21). L'élément étiré (1) est étiré entre les éléments de support (W1) et les sections de tête des deuxièmes tiges de structure (22) sont fixées par pivotement à la section médiane de l'élément étiré (1) de sorte que les premières tiges de structure (21) et les deuxièmes tiges de structure (22) aient à peu près la forme d'un losange.
