Abstract
A structural member having a longitudinal axis comprises: an exterior shell member defining an elongated channel with an inner surface; an interior shell member having an outer surface and defining an inner channel, inserted in the elongated channel of the exterior shell member and extending longitudinally therein and defining an inter-shell spacing therebetween; and concrete filling the inter-shell spacing and including at least one reinforcement bar having a longitudinally extending section extending in the inter-shell spacing and being disconnected from the inner surface of the exterior shell member and from the outer surface of the interior shell member.
Claims26
A structural member having a longitudinal axis comprising:
- an exterior shell member having two opposed ends and defining an elongated channel with an inner surface;
- an interior shell member having two opposed ends and having an outer surface and defining an inner channel, the interior shell member being inserted in the elongated channel of the exterior shell member and extending longitudinally therein;
- and
- concrete continuously filling space between the interior shell member and the exterior shell member and continuously covering the two opposed ends of the interior shell member with at least one reinforcement bar including a longitudinally extending section extending along the longitudinal axis and between the interior shell member and the exterior shell member and being disconnected from the inner surface of the exterior shell member and from the outer surface of the interior shell member, wherein at least one of the inner surface of the exterior shell member and the outer surface of the interior shell member comprises a polymeric coating including abrasive particles.
A structural member having a longitudinal axis comprising:
- an exterior shell member defining an elongated channel with an inner surface;
- an interior shell member having an outer surface and defining an inner channel, inserted in the elongated channel of the exterior shell member and extending longitudinally therein and defining an inter-shell spacing therebetween;
- and
- concrete filling the inter-shell spacing and including at least one reinforcement bar having a longitudinally extending section extending in the inter-shell spacing and being disconnected from the inner surface of the exterior shell member and from the outer surface of the interior shell member, wherein the inner channel of the interior shell member comprises opposed end sections, the concrete filling continuously the opposed end sections and the inter-shell spacing and wherein each one of the opposed end sections has a length, and the length of each one of the opposed end sections is between 5% and 20% of the length of the interior shell member.
A process for manufacturing a structural member, comprising:
- machining grooves on at least one of an inner surface of an exterior shell member, an outer surface of an interior shell member, and an inner surface of the interior shell member;
- inserting the interior shell member having an inner channel and two opposed ends in an elongated channel of the exterior shell member;
- inserting at least one reinforcement bar in an inter-shell spacing defined between the exterior shell member and the interior shell member;
- and
- filling inter-shell spacing with concrete with the at least one reinforcement bar being embedded in the concrete and the concrete continuously covering the two opposed ends of the interior shell member and filling partially the inner channel continuously from the two opposed ends wherein the grooves promote cohesion between the machined surface and the concrete.
