Abstract

The invention provides a reinforced concrete steel pipe column construction method. The reinforced concrete steel pipe column construction method includes, but not limited to, the following steps in sequence: mounting a column leg plate on a construction foundation, wherein the construction foundation is provided with an embedded connecting section and the embedded connecting section is arranged on the column leg plate in a penetrating manner and stretches out of the construction foundation; tying and connecting a reinforcement cage on the embedded connecting section; connecting tensioning pieces between the reinforcement cage and the construction foundation to enable the tied reinforcement cage to be in a vertical state; after the tying of the reinforcement cage is completed, lifting a steel pipe column, housing the reinforcement cage by using the steel pipe column from top to bottom and releasing the tensioning pieces; after the lifting of the steel pipe column is completed, mounting the steel pipe column on the column leg plate. The reinforced concrete steel pipe column construction method solves the problems that the existing ultrahigh small-section reinforced steel pipe column is difficult to construct and the like.

Description

technical field [0001] The invention relates to the technical field of building foundation engineering, in particular to a construction method for super-high small-section reinforced concrete steel pipe columns. Background technique [0002] In the construction of ultra-high and small-section reinforced concrete steel pipe columns with a height of more than 10m and a cross-sectional diameter of less than 1.5m, if the steel pipe column is installed first, the cross-sectional size of the steel pipe column is too small, and the ring plate is usually set inside the steel pipe column, so the reinforcement inside the steel pipe column Unable to bind. If the reinforcement inside the steel pipe column is constructed first, the steel cage is difficult to maintain verticality due to the high height, and the installation of the steel pipe column is very difficult. Contents of the invention [0003] In order to overcome the defects of the existing technology, a construction method fo...
