3 Fabrication method of composite structures using 3D concrete printing and machine-fabricated concrete filled tubes

摘要

The present invention relates to a three-dimensional concrete printing method integrated with a molded filled steel pipe structure and a composite structure manufactured by the printing method, and more particularly, to a plurality of steel pipes that are not filled inside are spaced apart from each other at a specific distance in the horizontal direction. a first step of arranging the longitudinal direction to be a vertical direction; a second step of laminating concrete through a three-dimensional concrete printer; A third step of installing a connecting member between the vertically arranged steel pipes when the laminated concrete reaches a certain strength; and a fourth step of integrating the steel pipe and the laminated concrete by filling the steel pipe with mortar.
