Concrete-filled steel tube column and casting method thereof

Abstract

The invention relates to a concrete-filled steel tube column and a casting method of the concrete-filled steel tube column, which are designed aiming at the technical problems of relatively poor compactness of concrete below a clapboard and inconvenient construction after a transverse clapboard is arranged for a similar product. The concrete-filled steel tube column comprises a steel tube, and a transverse clapboard with a casting hole inside the steel tube. The design key points are that bleeding holes are arranged in the wall of the steel tube, are positioned below the junction part of the transverse clapboard and the wall of the steel tube and are connected with the edges of the bottom surface of the transverse clapboard; and triangular air vents are arranged in the transverse clapboard. Due to the arrangement of the structure of the bleeding holes, an air chamber is unlikely to form when casting is conducted below the transverse clapboard, thereby being convenient for the discharge of gas and excess water. The concrete-filled steel tube column has a simple structure, is convenient for construction, not only can effectively improve the compactness of concrete casting inside the steel tube, but also can reduce the construction difficulty and improve the construction efficiency, and is especially suitable for concrete casting of existing steel tubes with a transverse strengthening plate or the improvement of structure of similar concrete columns.

Description

technical field [0001] The invention relates to a steel pipe concrete column, which is a steel pipe concrete column and a pouring method thereof. Background technique [0002] At present, the construction and development of super high-rise buildings in domestic cities is very rapid. The steel pipe concrete column is a composite structure that combines the advantages of steel pipe structure and reinforced concrete structure. It has been widely used in super high-rise building structures, and as an important structure. Stress member. The concrete-filled steel tube column mainly bears the vertical load of the building, up to hundreds or even thousands of tons. Therefore, the density of the concrete inside the steel tube is related to the safety of the bearing capacity of the entire super high-rise building structure system. Due to the structural force or structural requirements, in the structural design, it is necessary to install multiple transverse stiffening steel plates (o...
