Document Type and Number:
WIPO Patent Application WO/2023/231326
Kind Code:
A1
Abstract:
The present application relates to the technical field of engineering construction. Provided are a bar, device and construction method for a 3D printing concrete interlayer structure. The bar comprises at least a body of a chain-type structure, which comprises a plurality of sub-parts assembled with each other and is adapted to be sandwiched between two vertically adjacent cement-based slurry layers; a rotary joint, which is arranged between the two adjacent sub-parts to allow the two adjacent sub-parts to be rotatably connected to each other; and insertion portions, which are provided on two sides of each sub-part and extend away from the center of the sub-part, wherein the insertion portion on one side of the sub-part is adapted to be inserted into the upper cement-based slurry layer, and the insertion portion on the other side of the sub-part is adapted to be inserted into the lower cement-based slurry layer. In summary, by means of the bar, the bearing capacity of a printed structure in both the horizontal direction and the vertical direction can be enhanced to improve the overall connection strength of the printed structure, so that a building structure is not prone to damage or collapse, which is conducive to reduction of potential safety hazards.
