Title (EN) MEANS FOR DISCONNECTABLY COUPLING TOGETHER REINFORCING BARS
(FR) MOYEN POUR ASSUJETTIR DE MANIERE AMOVIBLE DES BARRES DE RENFORCEMENT ENTRE ELLES
Abstract: front page image
(EN)Means for disconnectably coupling together reinforcing bars, especially convenient for separating a part of a reinforced concrete structure. This coupling means (10) include a metal cylinder (15) in which any one of reinforcing bars to be coupled together is inserted at its end and adjoined to the cylinder, a thermally-destroyable member (16) arranged between the cylinder and reinforcing bar (11) and composed of thermally-destroyable substance, and a heating element (17) for heating and thus destroying the thermally-destroyable member (16) when the element is supplied with the electric current. The reinforcing bar (11) may be adjoined to the cylinder (15) by means of an adhesive (21). When the coupling means of this invention is employed at the reinforcing bar-coupling portion where the reinforcing bars are coupled together between a bridge floor and a reinforcing member for an expansion joint provided on the bridge floor at the bridge connecting location, the reinforcing member is, if desired, easily disconnected from the bridge floor.
(FR)Des moyens pour assujettir de maniere amovible des barres de renforcement, conviennent particulierement pour separer une piece d"une structure en beton arme. Ces moyens (10) comprennent un cylindre metallique (15) dans lequel l"une quelconque des barres de renforcement a assujettir est introduite par son extremite et jointe au cylindre, un organe destructible thermiquement (16) dispose entre le cylindre et la barre de renforcement (11) et compose d"une substance destructible thermiquement, et un element de chauffage (17) permettant de detruire l"organe destructible thermiquement (16) lorsque l"element recoit un courant electrique. La barre de renforcement (11) peut etre jointe au cylindre (15) au moyen d"un adhesif (21). Lorsque les moyens d"accouplement de cette invention sont utilises dans la partie d"accouplement des barres de renforcement ou les barres sont assujetties l"une a l"autre entre une base en pont et un organe de renforcement pour un joint d"expansion prevu sur la base en pont au point de connection du pont, l"organe de renforcement est, si on le desire, facilement deconnecte du sol ou base-pont.
