Abstract

Ensemble de boulon et d'écrou antivandalisme. L'ensemble, qui sert à assembler entre elles deux structures 2, 3, comporte un boulon 1 et un écrou 6 spécialement conçu qui comporte une base carrée 8 et quatre côtés inclinés formant une pyramide de sorte que cet écrou ne peut pas être entraîné en rotation par un outil classique. Pour monter et démonter l'écrou 6, on visse un dispositif coopérant, de préférence un écrou 7 similaire à l'écrou 6, dont la surface inclinée 9 fait face à la surface inclinée de l'écrou 6 ce qui permet de coincer un outil entre les deux écrous pour les entraîner en rotation de façon à serrer ou desserrer l'écrou intérieur 6. Après quoi, on retire l'écrou extérieur 7. Application aux dispositifs de fixation.
