Sea sand recycled concrete member for hollow double-skin steel pipe
The invention belongs to the field of engineering structures, and particularly relates to a sea sand recycled concrete member for a hollow double-skin steel pipe. The member is characterized in that the inner surface of an outer steel pipe and the outer surface of an inner steel pipe are coated with epoxy resin; the space formed by encircling of the inner steel pipe and the outer steel pipe is filled with the sea sand recycled concrete. Because a form of the cross section of the hollow double-skin is adopted, the axial load strength of the hollow double-skin steel pipe sea sand recycled concrete is not smaller than that of solid steel pipe concrete, and the anti-bending bearing capability and the fireproof high-temperature resistant performance are greatly improved; the surface layers of the inner steel pipe and the outer steel pipe are coated with epoxy resin, the corrosion of the steel pipes is avoided; moreover, the inner part of the steel pipes is filled with the sea sand recycled concrete, so that the bearing capability and the deformation capability of the concrete can be improved, and the safety hidden danger of the sea sand can be reduced, and a combination function can be fully achieved. By using the member, the application of the sea sand recycled concrete member is improved, energy source conservation and renewable resource utilization are fully achieved, and the sea sand recycled concrete member has a good social and economic benefit.
