Steel structure fabricated residual prefabricated concrete-filled steel tubular column and manufacturing method thereof

Abstract

The invention relates to the field of steel structure fabricated building construction engineering, in particular to a fabricated residual prefabricated concrete-filled steel tubular column and a manufacturing method thereof. The prefabricated concrete-filled steel tubular column comprises a steel tubular column, and is characterized in that a grouting hole and a vibrating hole are formed in a topplate of the steel tubular column, a concrete layer is poured into the steel tubular column, butt-joint cavities are correspondingly formed in the upper and lower butt-joint ends, the lower butt-joint cavity is internally provided with a special-shaped sealing plate for blocking the concrete layer, a prefabricated observation pipe and a prefabricated grouting pipe which communicate with the lowerbutt-joint cavity are correspondingly arranged on the special-shaped sealing plate, and the prefabricated observation pipe and the prefabricated grouting pipe are correspondingly connected with a steel column observation air hole and a steel column grouting hole in two side arms of the steel tubular column. According to the fabricated residual prefabricated concrete-filled steel tubular column, the concrete-filled steel tubular column is subjected to prefabrication grouting, according to the requirements of the construction site, the concrete-filled steel tubular column is prefabricated in advance in a factory, the concrete-filled steel tubular column is hoisted in place after prefabricated parts are transported to the site, the steel column factory prefabrication grouting is achieved, the construction progress of the project is accelerated, and the overall assembly rate of the project is improved.

Description

technical field [0001] The invention relates to the field of steel structure assembly building construction engineering, in particular to an assembly type residential factory prefabricated steel pipe concrete column and a manufacturing method thereof. Background technique [0002] In industrial and civil construction projects, most engineering pouring methods use concrete pouring on site, because of the many construction procedures and great difficulty, quality problems are prone to occur during construction, such as grouting is not dense, etc.; Both the technical level of personnel and the management level of managers have relatively high requirements. Contents of the invention [0003] The present invention aims to solve the above problems, thereby providing a prefabricated steel pipe concrete column in a prefabricated residential factory and its manufacturing method, which can change the concrete pouring method on site, reduce construction procedures, reduce constructio...
