A scs concrete filled steel pipe pier with a built-in transverse connection structure at the end

Abstract

The invention discloses an SCS concrete filled steel tube pier with transverse connecting structures arranged inside the two ends. The SCS concrete filled steel tube pier with the transverse connecting structure arranged inside the two ends comprises an outer steel tube, an inner steel tube, a top end connecting structure, a bottom end connecting structure and a concrete structure arranged between the outer steel tube and the inner steel tube, wherein both the outer steel tube and the inner steel tube are arranged vertically and coaxially, the top end connecting structure and the bottom end connecting structure are the transverse connecting structures which are both arranged between the outer steel tube and the inner steel tube, each transverse connecting structure comprises multiple groups of transverse connecting pieces which are arranged in the circumferential direction, each group of transverse connecting pieces comprises multiple transverse connecting pieces which are arranged from top to bottom, each transverse connecting piece is formed by connecting an outer connecting piece body and an inner connecting piece body, the outer connecting piece bodies are parallel to the inner connecting piece bodies, and the inner end of each outer connecting piece body and the outer end of the corresponding inner connecting piece body are connected into a whole. The SCS concrete filled steel tube pier with the transverse connecting structure arranged inside the two ends is simple in structure, reasonable in design, convenient to construct, low in construction cost, excellent in mechanical property, good in use effect and capable of solving multiple problems of existing concrete filled steel tube piers.

Description

Technical field [0001] The invention relates to a steel tube concrete pier, in particular to an SCS steel tube concrete pier with a built-in transverse connection structure at the end. Background technique [0002] Concrete-filled steel tube refers to the structure formed by filling steel tube with concrete. The two materials, steel and concrete, make up for each other's weaknesses and give full play to each other's strengths, so that concrete-filled steel tubes have high bearing capacity and excellent mechanical properties. Nowadays, concrete-filled steel tube structures are more and more widely used in offshore platforms and large-span, heavy-duty, light-duty bridges and other structures, and the concrete-filled steel tube structures used mainly have three cross-sectional forms: round, square and rectangular. [0003] At present, the concrete-filled steel tube piers used have the following defects: first, the self-weight limits the structural size of the pier; second, for certai...
