Example Embodiment

[0038] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0039] reference figure 1 with figure 2 As shown in the simplified schematic diagram of the process and structure, the present invention includes a dual-nozzle concrete printing process, which includes the transmission of concrete slurry, foamed resin or (and) other necessary admixtures, the distribution of the printing process, and the concrete slurry The transportation and addition of the required additives, the printing and modification of the building structure, the timely cleaning of the nozzles in the printing gap during the printing process, and the cleaning of the pipelines and nozzles after the printing. The transmission of concrete slurry is realized by the mixer 1 and the shotcrete equipment 3. The cement, fine sand and water are fully mixed in the mixer 1 and then the opening and closing valve 2 is opened and the material is dropped into the shotcre...

Abstract

The invention belongs to the field of 3D printing and particularly relates to a double-nozzle concrete printing device and printing method. The device comprises a three-axis motion platform and further comprises a spray head device A, a spray head device B and a blade stirring and discharging device located above the three-axis motion platform. The spray head device A is used for spraying concretegrout. The spray head device B is used for spraying foaming resin or a wet mixed material. The blade stirring and discharging device is used for adding a dry mixed material into a workpiece to be printed. The printing method comprises the steps of conveying of the concrete grout, the foaming resin or (and) other necessary mixed materials, distribution of the printing process, transporting and adding of additives required in the concrete grout, printing and shape correction of building structural parts, cleaning of the interiors of spray heads during printing breaks and cleaning after completion of printing. The double-nozzle concrete printing device can realize efficient and rapid forming of large building structural parts containing different reinforcing materials, gives sufficient consideration to the printing precision and the mechanical performance of the building structural parts and provides a new process idea for application of building materials in the field of additive manufacturing.

Description

technical field [0001] The invention belongs to the field of 3D printing, and in particular relates to a double-nozzle concrete printing device and a printing method. Background technique [0002] When 3D printing is applied to the construction field, there is no mature application-oriented process or equipment at present, and they are all in the laboratory stage. There are still a series of problems to be solved around materials, processes and equipment. In order to further improve the high-performance application of 3D printing in the construction field, the present invention proposes a dual-nozzle printing process, through which the high-speed and efficient multi-material complex structure molding of ordinary cement powder materials can be realized. Contents of the invention [0003] The object of the present invention is to provide a dual-nozzle concrete printing device and a printing method. [0004] The technical solution to achieve the purpose of the present invent...
