Abstract

The invention discloses a concrete-filled steel tube column-U-shaped steel plate combined beam frame. The concrete-filled steel tube column-U-shaped steel plate combined beam frame comprises a hollow steel pipe, a plurality of U-shaped steel plates, connecting components, a plurality of open steel bar skeletons and a steel reinforcement cage, wherein the hollow steel pipe is circumferentially and uniformly provided with a plurality of steel pipe wall holes; one end of each U-shaped steel plate is fixed to the corresponding steel pipe wall hole, and the other end of each U-shaped steel plate outwards extends relative to the corresponding steel pipe wall hole; the multiple sets of symmetrical connecting components are all arranged on the inner walls of the U-shaped steel plates; the two open ends of each open steel bar skeleton are separately arranged on the corresponding connecting component; and the steel reinforcement cage is sleeved with the hollow steel pipe. The concrete-filled steel tube column-U-shaped steel plate combined beam frame has the advantages of being simple in joint structure, definite in stress, convenient to construct and the like.

Description

technical field

[0001] The invention relates to the technical field of steel and concrete composite frames, in particular to a steel tube concrete column-U-shaped steel plate composite beam frame. Background technique

[0002] Steel and concrete composite structure is a common structural form in modern building structures. Because it can give full play to the mechanical advantages of the two materials, it is widely used in large-span structures and high-rise buildings. It also has good ductility, which expands its range of applications. Commonly used composite columns in engineering include concrete-filled steel tubular columns, stiff concrete columns, and composite beams include profiled steel-concrete composite beams and stiff concrete beams, which are combined in pairs to form different types of composite frames. Among them, the most widely used are concrete-filled steel tube-steel-concrete composite beam frame, concrete-filled steel tube column-stiffened beam frame, and...
