A filled hollow structure (10), such as a fence post, which is constructed with a hollow member (14) filled with a core (12) to increase its strength. One aspect of the structure is that the core material normal expands upon setting, so that, when hardening within the hollow member, the expansion is restrained by the hollow member and the core is formed into an integral structure with the hollow member. Further strength is added by constructing the hollow member of reinforced fiberglass with the fiberglass rovings oriented at an angle to the axis of the pipe and by using a hard coating (18) on the outside of the pipe.
L'invention concerne une structure creuse (10) garnie, telle qu'un piquet de barrière. Ladite structure se compose d'un élément creux (14) garni d'un noyau (12) qui augmente sa solidité. Le matériau constituant le noyau se dilate normalement lors de la prise, de sorte que lorsqu'il durcit à l'intérieur de l'élément creux, la dilatation est restreinte par l'élément creux et le noyau forme une structure intégrée à ce dernier. On augmente encore la solidité, en utilisant de la fibre de verre renforcée comprenant des stratifils de verre textile orientés selon un certain angle par rapport à l'axe du tuyau et en utilisant un revêtement dur (18) sur l'extérieur du tuyau.
