Building 3D printing wall

Abstract

The invention discloses a building 3D printing wall. The printing wall comprises a 3D printing inner wall layer, a poured reinforced concrete layer and a 3D printing outer wall layer, no steel reinforcing ribs affecting moving of a printing head exist in the printing inner and outer wall layers of the 3D printing wall, concave and convex parts of upper and lower faces of adjacent printing layers are correspondingly engaged, therefore, it is ensured that in the printing process, moving of the printing head cannot be affected by steel reinforcing ribs, it is ensured that the printed wall is stable, meanwhile, the inner side face of the inner wall layer and the outer side face of the outer wall layer are smeared to be flat, on one hand, the printing layer density is improved, the inner wall layer and the outer wall layer of printing can be improved in firmness, and on the other hand, the subsequent leveling manpower cost and material cost can be saved.

Description

technical field [0001] The invention relates to a building 3D printing wall, which belongs to the field of building 3D printing. Background technique [0002] At present, the reinforced concrete shear wall of high-rise buildings usually adopts prefabricated steel cages, and the installation formwork is made outside the steel cage, and then concrete is poured into the formwork cavity. The formwork and subsequent dismantling of the formwork are labor-intensive and time-consuming. It also caused a lot of wood consumption and loss. If there is no need to make templates, the inner and outer wall layers are made by 3D printing, and then concrete is poured, which saves a lot of manpower and material resources and reduces construction costs. In the patent CN204738415U and the patent CN206438674U, a kind of architectural 3D printing wall is introduced, and the concrete wall is poured in the middle of the inner and outer printed walls. In order to ensure the stability of the inner and...

[0002] At present, the reinforced concrete shear wall of high-rise buildings usually adopts prefabricated steel cages, and the installation formwork is made outside the steel cage, and then concrete is poured into the formwork cavity. The formwork and subsequent dismantling of the formwork are labor-intensive and time-consuming. It also caused a lot of wood consumption and loss. If you don’t need to make templates, you can use 3D printing to make the inner and outer wall layers, and then pour concrete, which saves a lot of manpower and material resources and reduces construction costs.

In the patent CN204738415U and the patent CN206438674U, a kind of architectural 3D printing wall is introduced, and the concrete wall is poured in the middle of the inner and outer printed walls. In order to ensure the stability of the inner and outer walls, steel bars are arranged in the inner and outer walls. During the printing process, The arranged steel bars will interfere with the print head, affect the movement of the print head, cause printing inconvenience, and have an adverse effect on the continuity of the printing process. If no steel bars are arranged in the inner and outer walls of the print, it can also ensure The height and direction of the printing layer are stable, which will greatly promote the expansion of 3D printing in the construction field
