A kind of horizontal structure 3D printing method

Abstract

The invention provides a horizontal structure 3D printing method, which adopts a mobile 3D printing robot, a free-following template device and an external support structure. The mobile 3D printing robot includes a plurality of first rope driving and guiding mechanisms, a moving platform, a printing head mechanism and a printing head The connecting mechanism, the first rope driving and guiding mechanism includes a first rope driving and braking mechanism, a first high-strength rope, a first rope guiding mechanism and a first fixing assembly, and the first high-strength rope is retracted and retracted by the first rope driving and braking mechanism to realize the The precise printing positioning of the moving platform; the free follow-up template device includes several second rope drive guide mechanisms and follower templates, and the second rope drive guide mechanism includes a second rope drive brake mechanism, a second high-strength rope, and a second rope guide mechanism And the second fixing component, the second high-strength rope is retracted and retracted by the second rope driving and braking mechanism to realize the precise positioning of the follower template, which has the advantages of light weight, small size, easy installation and high automation.

Description

technical field [0001] The invention belongs to the technical field of architectural 3D printing, and in particular relates to a horizontal structure 3D printing method. Background technique [0002] The degree of mechanization and automation of the traditional construction industry is low, and its development urgently needs transformation and upgrading. With the development and maturity of 3D printing technology, this technology will bring technological innovation to the labor-intensive construction industry. Architectural 3D printing technology has the characteristics of high degree of mechanization and automation, one-time molding, less construction consumables and process loss, etc. Way, its research has become the development trend of the construction industry. [0003] The 3D printing construction of long-span horizontal structures is one of the biggest challenges of architectural 3D printing. Due to the limitations of materials and devices, and the inability of hori...

AI Technical Summary

Problems solved by technology

[0005] The present invention aims to invent a horizontal structure 3D printing method, which provides a supporting load-bearing mechanism for a mobile 3D printing robot through an external support structure so as to provide a printing space compatible with the printing structure, and through a free follow-up template device fixed to the external support structure Dynamically adjust the movement to provide a bottom support platform for horizontal structure printing, and complete the printing and construction of the horizontal structure through the mobile 3D printing robot's collaborative printing job, solving the problem that the existing 3D printing devices and methods cannot realize the overall printing of the horizontal structure, and the printing cannot be fully automated. Horizontal structure printing is limited by the printing shape of materials, etc., to achieve efficient, safe and automatic construction of horizontal structures
