Steel tube foam concrete combined upright column and construction method thereof

Abstract

The invention relates to a steel tube foam concrete combined upright column and a construction method of the steel tube foam concrete combined upright column. The steel tube foam concrete combined upright column comprises an upright column body, wherein the upright column body comprises steel tubes (2), foam concrete (3), reinforcing meshes (4) and outer wrapped concrete layers (5), wherein the foam concrete (3) is poured into the steel tubes (2); the reinforcing meshes (4) are arranged on the outer walls of the steel tubes; the steel tubes are connected by virtue of flange discs (6) and flange sockets (7); and a gasket (8) is arranged between each flange disc (6) and each flange socket (7). The foam concrete in the steel tube foam concrete combined upright column can adopt coal ash foam concrete or ceramsite foam concrete. The steel tube foam concrete combined upright column has a simple structure, and is high in shock resistance, high in carrying capability, good in economical performance and easy to construct, and suitable for main support columns and support parts of house structures, industrial building structures, recreational and athletic building structures and other structures.

Description

technical field [0001] The invention relates to a steel pipe foam concrete composite column and a construction method thereof, which can be used in the technical field of construction engineering. Background technique [0002] The steel pipe foam concrete composite column refers to a composite column in which the steel pipe is filled with foam concrete and the outer wall of the steel pipe is provided with a concrete protective layer. [0003] CFST columns were introduced into China in the mid-1960s. In less than 50 years, CFST technology has developed rapidly both in theory and technology. Most of the CFST columns used in existing industrial and civil buildings are It is simply made by pouring ordinary cement concrete in the steel pipe. Early concrete-filled steel tube columns greatly compensated for the high brittleness of concrete through the lateral restraint of the steel tubes on the concrete; at the same time, the concrete filled in the steel tubes limited the deformat...
