Title (EN) REMOVABLE BOLLARD SYSTEM AND METHOD OF INSTALLATION
(FR) systeme de bollards amovibles et procede de montage
Abstract: front page image
(EN)An anti-ram removable bollard (10) assembly and an installation of the same to arrest impacts are provided. The removable bollard assembly comprises a base assembly (20) and at least a reinforcement member (32a,32b) to be fixedly installed on site, and a removable bollard member to be detachably secured to the base assembly as and when required. A coupling mechanism (42,44,48) may be provided in the base assembly to engage the removable bollard member. Also, the base assembly may include an I-beam cross-section arrangement (22,24,26) to provide increased strength to the base assembly. Several base assemblies may be connected by rebars (104) to form a cohesive installation which restrains movement when any bollard member in the installation is struck. With the cohesive arrangement, a high impact rating may be achieved even with shallow base assemblies.
(FR)L'invention a pour objet un ensemble bollard amovible anti-renversement et son installation pour empêcher les impacts. L'ensemble bollard comprend une structure de base, au moins un élément de renforcement à monter de manière fixe et un élément bollard mobile à fixer de manière amovible à la structure de base au besoin. La structure de base peut comporter un mécanisme de raccordement pour mettre en prise l'élément bollard mobile. De même, la structure de base peut comprendre un dispositif de barres à section en I pour une résistance accrue. Plusieurs structures de base peuvent être reliées par des barres d'armature pour former une installation cohésive qui limite les mouvements lorsqu'un élément bollard de l'installation subit un choc. Cette disposition cohésive permet de résister à beaucoup d'impacts même si les structures de base sont basses.
