Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of building engineering, and particularly relates to a high-throwing self-compacting steel pipe concrete column and a construction method. BACKGROUND

[0002] With the development of building construction technology, the application of steel pipe concrete is more and more widely, and at present, there are three steel pipe concrete pouring methods, i.e. high-throwing free-vibrating method, vertical hand pouring method and pumping lifting pouring method. The steel pipe column filled with concrete can fully exert the advantages of steel structure and concrete structure, meet the mechanical performance requirements of high strength, high elastic modulus, low shrinkage, low creep, early strength, certain growth of late strength and the like, and the concrete has good workability. Compared with ordinary concrete, the high-throwing self-compacting steel pipe concrete has higher requirements for the performance, mechanical performance and volume stability of the concrete mixture. The high-throwing self-compacting steel pipe concrete combines the technical difficulties of the high-throwing self-compacting concrete and the steel pipe concrete, and is often required to have high concrete strength when used in high-rise buildings, and has the characteristics of high-strength concrete, which is a relatively complex and extremely challenging new type of concrete technology.

[0003] At present, the steel pipe concrete column construction has the problems of poor construction platform safety and low construction efficiency; due to the complex internal structure of the steel pipe column and many horizontal and vertical inner partitions, the traditional method is to use the guide pipe method for pouring, a long guide pipe is inserted into the steel column from the top of the steel column, the concrete freely falls into the bottom of the steel column from the guide pipe, and the self-compacting free-vibrating purpose is achieved by using the kinetic energy of the concrete itself. However, during the construction process, due to the lateral pressure of the upper concrete pouring and the gravity of the long guide pipe itself, the guide pipe is prone to shaking, displacement and falling during the concrete pouring period, which brings great inconvenience to the construction and seriously affects the pouring quality of the column core concrete. In addition, there are problems such as the difficulty of subsequent construction caused by the entry of rain and snow into the steel pipe column in rainy and snowy weather, and the difficulty of maintenance after the steel pipe concrete column is poured. Therefore, a new measure is needed to solve these problems. SUMMARY
