Hollow interlining FRP-steel tube sea sand recycled concrete member
The invention belongs to the field of engineering structures and particularly relates to a hollow interlining FRP-steel tube sea sand recycled concrete member. According to the hollow interlining FRP-steel tube sea sand recycled concrete member, the outer surface of an outer steel tube is coated with an FRP material layer in a pasting mode, and sea sand recycled concrete is filled between the inner surface of the outer steel tube and the outer surface of an inner steel tube. By the adoption of a hollow interlining section form, the axle load bearing capacity of the hollow interlining FRP-steel tube sea sand recycled concrete member is not lower than that of solid steel tube concrete, and the flexural capacity and the fire-resistant and high temperature-resistant performance are further improved; the outer surface of the outer steel tube is coated with the FRP material layer in a pasting mode, so that the corrosion to the steel tube from external environment of corrosion areas such as coastal areas and offshore areas is avoided; the sea sand recycled concrete is filled into the steel tubes, so that the bearing capacity and the deformability of the concrete are improved, the potential safety hazard of the sea sand is lowered, and the combination function is fully played. The FRP-steel tube sea sand recycled concrete member promotes the application of the sea sand recycled concrete, energy sources are fully saved, the renewable resources are fully used, and the good social benefits and economic benefits are achieved.
