Closed inclined steel pipe column concrete jacking construction method

Abstract

The invention belongs to the technical field of construction, particularly relates to a concrete jacking construction method for a closed inclined steel pipe column, and provides the following scheme aiming at the problems of poor stability and inconvenience in operation in the prior art: the closed inclined steel pipe column comprises a steel column body; an annular supporting reinforcing steel plate, a concrete connecting pump pipe, a check valve connecting end plate A, a check valve connecting end plate B, a check valve plate, a bolt and an exhaust grout outlet pipe are arranged on the surface of the steel column body, and a hole in the rear side of the annular supporting reinforcing steel plate communicates with a hole in the bottom end of the surface of the steel column body. Time and labor are saved; in the pouring process, due to the fact that the overall stability is high, the method is suitable for on-site medium-high inclined steel columns, certain economic benefits are achieved, the green construction requirement is met, the whole steel pipe column is directly installed and fixed, the on-site steel pipe column welding amount is greatly reduced, and meanwhile multiple times of measurement and adjustment in the construction process are avoided.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a closed-type inclined steel pipe column concrete jacking construction method. Background technique [0002] With the rapid development of China's economy, national construction, urban construction and new rural construction continue to strengthen, with more and more large spans and floor spacings, and high-rise and super high-rise buildings emerge one after another. CFST columns fully combine the advantages of steel tubes and concrete, and have good ductility and high bearing capacity, making them have broad development prospects in super high-rise and long-span structures. When the concrete-filled steel tube is lifted and poured, it enters the steel tube from bottom to top. The construction of the jacking method can make the concrete column not need to vibrate with a vibrating rod, save time, keep the pouring quality intact, and the concrete has good compactness. The const...
