Abstract

L'invention concerne un système de supports temporaires de construction ou de démolition réglables. Le support temporaire de construction ou de démolition réglable selon l'invention comprend une pluralité de dispositifs capteurs destinés à mesurer la charge exercée sur le support et un dispositif de détection et de communication de signal en communication avec les dispositifs capteurs. Le dispositif de communication comprend de plus une unité d'affichage et/ou une unité de sortie audio permettant de produire une alarme visuelle et/ou audible pour des situations d'alarme. Le dispositif de détection et de communication de signal comprend de plus un émetteur-récepteur sans fil pour la surveillance à distance.
