Title:
3D PRINTING-BASED BUILDING STRUCTURE MANUFACTURING DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2020/113907
Kind Code:
A1
Abstract:
A 3D printing-based building structure manufacturing device. Said device comprises a 3D printing apparatus (1) and a reinforcement apparatus; the 3D printing apparatus has a storage cavity (11) and a print head (12) connected to the storage cavity (11) and movable relative to a base frame; the reinforcement apparatus is provided movably relative to the base frame, and has a driving mechanism (3) for driving short reinforcing bars or short ribs to perform an insertion movement in a direction intersecting with the direction of stacking of cement-based slurry layers, the driving mechanism (3) inserting the short reinforcing bars or short ribs into interfaces at least crossing two adjacent cement-based slurry layers printed by the 3D printing apparatus (1). Further provided is a 3D printing-based building structure manufacturing method. There is no printing gap between the cement-based slurry layers printed by said device and the reinforcing bars inserted, ensuring tight connection between the cementitious slurry and the reinforcing bars, improving the mechanical performance and toughness of interfaces between the 3D-printed cement-based material layers.
