Problems solved by technology

[0002] The doors and windows of the existing building contours cannot directly reserve space at their positions due to the lack of support. Although the position of the doors and windows can be pre-added with isolation and support materials, such as wood and steel plates, it increases the process and materials, which is time-consuming. labor, uneconomical

Embodiment 1

[0031] Such as figure 2 As shown, an embodiment of the supporting wall printing nozzle of the present invention, the easy-to-remove material of this embodiment is styrofoam, and the supporting wall printing nozzle and the 3D printing nozzle are two independent printing nozzles.

[0032] The supporting wall printing nozzle includes a foaming gun 31 and a foaming agent solution delivery pipeline and a compressed air delivery pipeline connected to the foaming gun 31 respectively;

[0033] The foaming agent solution conveying pipeline is connected with a quantitative infusion pump 32 for conveying the foaming agent solution, a control valve 33 and a first flowmeter 34 for controlling the opening / closing of the pipeline, and the compressed air conveying pipeline is provided with a regulator Pressure valve 35, the second control valve 36 and the second flowmeter 37; The feed port of the pipeline is connected with the compressor, and the compressed air is delivered to the foaming g...

Embodiment 2

[0036] Such as image 3 Shown: an embodiment of the 3D printing nozzle of the present invention, the difference between this embodiment and embodiment 1 is that the material that is easy to dig out is concrete whose setting time is longer than that of the material used when printing the wall Material; retarder is added in the concrete material of printing support wall 8. The 3D printing nozzle not only serves as the printing nozzle of the main wall 1, but also serves as the printing nozzle of the supporting wall, that is, the 3D printing nozzle and the printing nozzle of the supporting wall are the same printing nozzle.

[0037]The 3D printing nozzle includes a mixing part 21, and a mixing cavity is arranged inside the mixing part 21; an upper end cover 27 is arranged on the upper end of the mixing part 21, and a spray nozzle 23 is arranged on the lower end; the upper end cover 27 is provided with multiple A primary material inlet 22 communicated with the mixing chamber;

Abstract

The invention provides a building wall body 3D printing method. A 3D printing sprayer head is used for printing a main wall body. When a pre-opening position of the main wall body begins to be printed, a supporting wall is printed in the pre-opening position of the main wall body with materials easy to dig out. After printing of the main wall body is finished, the supporting wall is dug out through a digging tool. The invention further provides building 3D printing equipment supporting the building wall body 3D printing method. The supporting wall is arranged in the pre-opening position, the printing materials of the supporting wall are easy to dig out later, the supporting wall has a supporting function in the printing process of the wall body, and after printing is finished, the digging tool can be used for directly digging out the supporting wall portion. The building wall body 3D printing method is convenient and rapid to operate, is low in cost, lowers the construction cost and greatly improves the construction progress. In addition, coloring pigments convenient to differentiate are added into the printing materials of the supporting wall, and thus the digging boundary can be rapidly determined in digging operation, and the construction speed is improved.

Description

technical field [0001] The invention belongs to the field of construction engineering, and in particular relates to a method for 3D printing building walls and equipment for 3D printing buildings. Background technique [0002] The doors and windows of the existing building contours cannot directly reserve space at their positions due to the lack of support. Although the position of the doors and windows can be pre-added with isolation and support materials, such as wood and steel plates, it increases the process and materials, which is time-consuming. work, not economical. How to solve the problem of door and window reservation without affecting the use is a technical problem that the current research and development personnel urgently need to solve. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-efficiency and low-cost method for 3D printing building walls in view of the deficiencies in the prior art. ...
