The printing head is movably arranged on one side of the steel frame and is used for 3D printing prefabricated building components. The push plate is movably arranged relative to the steel frame and is on the same side as the printing head and is used to push the prefabricated building components printed by the printing head so that the inner surface of the prefabricated building components is combined with one side of the steel frame. The push plate is also used to flatten the outer surface of the prefabricated building components.

[0033] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0036] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0037] Reference Figures 1 to 4The preferred embodiment of the present invention provides a flat-push printing device for steel skeleton prefabricated building components, comprising a print head 10 and a push plate 20. The print head 10 is movably arranged on one side of a steel skeleton 30 and is used for 3D printing a prefabricated building component 40. The steel skeleton 30 is fixed on a casting substrate 31 and extends in a vertical direction. The prefabricated building component 40 printed by the print head 10 is supported by the casting substrate 31. The print head 10 is a print head 10 of a 3D printing device. The push plate 20 is movably arranged relative to the steel skeleton 30 and is located on the same side of the steel skeleton 30 as the print head 10. The push plate 20 is used to push the prefabricated building component 40 printed by the print head 10 so that the inner surface of the prefabricated building component 40 is combined with one side of the steel skeleton 30, and the outer surface of the prefabricated building component 40 is flattened under the push of the push plate 20. When the flat-push printing device of the steel skeleton prefabricated building component of the present embodiment is used, the prefabricated building component 40 is first 3D printed on one side of the steel skeleton 30 by the print head 10. Of course, in order to prevent the steel skeleton 30 from interfering with the printing of the print head 10, there is a certain distance between the print head 10 and the steel skeleton in the horizontal X direction. When the print head 10 prints the prefabricated building component 40, the push plate 20 pushes the prefabricated building component 40 printed by the print head 10 so that the inner surface of the prefabricated building component 40 is combined with one side of the steel skeleton 30. At the same time, the outer surface of the prefabricated building component 40 is also flattened under the push of the push plate 20 to achieve the effect of smoothing the outer surface of the prefabricated building component, thereby effectively solving the problem that it is difficult to embed the prefabricated steel skeleton into the printing material in the prefabricated building component of the traditional 3D printing technology, and solving the defect that the outer surface of the prefabricated building component 40 of the traditional 3D printing technology has poor aesthetics and flatness.

[0038] Of course, in other embodiments, the push plate 20 is not limited to the structure shown in the following figures. For those skilled in the art, by reasonably changing the push plate 20 to achieve the structure of pushing the prefabricated building component 40 and smoothing the outer surface of the prefabricated building component 40, it should also fall within the protection scope of the present invention.

[0039] In addition, it is worth mentioning that through the solution of combining the print head 10 and the push plate 20, when printing relatively high walls or columns, the walls or columns can be set horizontally, so that the factory building and printing equipment do not need to be set up very tall, thereby enhancing the stability of the printing equipment and the quality of the printed prefabricated parts.

[0040] It should be noted that the configured 3D printing material (concrete material) meets the requirements for extrusion, fluidity, self-stability and printability, that is, the extrusion performance, fluidity and self-stability of the material (concrete), and its corresponding indicators meet the continuous working performance requirements of 3D printing.

[0041] As a preferred embodiment of the present invention, it may also have the following additional technical features:

[0042] In this embodiment, the inner surface of the prefabricated building component 40 is formed with concave-convex patterns, and the contact area between the inner surface of the prefabricated building component 40 and the steel frame 30 can be increased through the concave-convex patterns, thereby enhancing the bonding strength between the two, ensuring that the prefabricated building component 40 and the steel frame 30 are condensed into one, and the bonding effect is better.

[0043] In this embodiment, the push plate 20 is also connected to a driving device. Of course, the driving device is also located on one side of the steel frame 30 and on the same side as the push plate 20. The driving device drives the push plate 20 to push the prefabricated building component 40, so as to achieve the effect of automatic pushing of the push plate 20, and further improve the efficiency of combining the inner surface of the prefabricated building component 40 with the steel frame 30 and smoothing the outer surface of the building component. The driving device of this embodiment can be an electric push rod or a linear drive motor, which is not limited here. For those skilled in the art, by reasonably changing the structure of the driving device of this embodiment, it should also fall within the protection scope of the present invention.

[0044] In this embodiment, a print head 10 and a push plate 20 may also be provided on the other side of the steel frame 30, that is, the above-mentioned print head 10 and push plate 20 are provided on opposite sides of the steel frame 30, so as to realize the printing of prefabricated building components 40 on both sides of the steel frame 30, which can greatly improve the printing efficiency.

[0045] In this embodiment, the print head 10 can move in the vertical and horizontal directions relative to the steel frame 30. A plurality of push plates 20 are provided, and the plurality of push plates 20 are arranged in the vertical direction. The movement directions of the push plates 20 are the same. Of course, the push plates 20 are also connected to the above-mentioned driving devices, and the driving devices are used to drive the movement of the push plates 20. Through this solution, the prefabricated building components 40 can be printed in layers.

[0046] Specifically, it can be understood that the plurality of push plates 20 in this embodiment are respectively the first push plate 20, the second push plate 20 from bottom to top, and so on; the driving device drivingly connected to the first push plate 20 is the first driving device, the driving device drivingly connected to the second push plate 20 is the second driving device, and so on; the plurality of prefabricated building components 40 printed out in layers from bottom to top by the print head 10 are respectively the first prefabricated building component 40, the second prefabricated building component 40, and so on; of course, the first prefabricated building component 40 corresponds to the first push plate 20, the second prefabricated building component 40 corresponds to the second push plate 20, and so on; when printing, the print head 10 first prints out the first prefabricated building component 40, and then drives the first push plate 20 to push the first prefabricated building component 40 through the first driving device The first prefabricated building component 40 is printed, so that the inner surface of the first prefabricated building component 40 is combined with the steel frame 30 and the outer surface of the first prefabricated building component 40 is flattened; then the second prefabricated building component 40 is printed on the upper surface of the first push plate 20, and finally the first push plate 20 is driven by the second driving device to push the second prefabricated building component 40, so that the inner surface of the second prefabricated building component 40 is combined with the steel frame 30 and the outer surface of the second prefabricated building component 40 is flattened. In this way, the layered printing of the prefabricated building component 40 can be completed, thereby effectively avoiding that the prefabricated building component 40 (such as a wall) printed as a whole is too large, resulting in the inner surface of the prefabricated building component 40 not being well combined with the steel frame and the outer surface not being easy to smooth.

[0047] It should be emphasized that the setting mode in which the print head 10 can be moved in the vertical direction relative to the steel frame 30 can adopt linear guides, lifting mechanisms and other structures commonly used in machinery, the setting mode in which the print head 10 can be moved in the horizontal direction relative to the steel frame 30 can adopt linear guides and other structures commonly used in machinery, and the setting mode in which the push plate 20 can be moved in the horizontal direction relative to the steel frame 30 can adopt linear guides commonly used in machinery. These are relatively mature technologies in the mechanical field, and their specific settings and structures will not be elaborated here.

[0048] In addition, the present invention also provides a printing method for a prefabricated building component 40 of a steel skeleton 30, using the flat-push printing device of the present invention, comprising the following steps:

[0049] S1. Data analysis: analyzing the data of the prefabricated building component 40 to be printed, and generating model data of the prefabricated building component 40;

[0050] S2. Arrange the print head 10: movably arrange the print head 10 on one side of the steel frame 30 in the vertical direction, and make the print head 10 and the steel frame 30 separated by a certain distance in the horizontal X direction;

[0051] S3, printing prefabricated building components 40: the print head 10 3D prints out the prefabricated building components 40 which are spaced apart from the steel skeleton 30 in the horizontal X direction according to the above model data;

[0052] S4, arranging the push plate 20: movably arranging the push plate 20 on one side of the steel frame 30 along the horizontal X direction and making the push plate 20 and the print head 10 on the same side;

[0053] S5. Combining the prefabricated building component 40 with the steel frame 30: After the prefabricated building component 40 is printed out by the print head 10, the push plate 20 is pushed to move along the horizontal X direction. The push plate 20 is pushed by the above-mentioned driving device to combine the inner surface of the prefabricated building component 40 with the steel frame 30, and the outer surface of the prefabricated building component 40 is flattened by the push plate 20.

[0054] It can be seen that the printing method of the steel skeleton 30 prefabricated building component 40 in this embodiment can solve the defect of poor outer surface aesthetics and flatness of the prefabricated building component 40 printed by traditional 3D printing, and there is no need to manually smooth the outer surface of the prefabricated building component 40, thereby improving the efficiency of smoothing the outer surface of the prefabricated building component 40.

[0055] It should be noted that the data of the prefabricated building components 40 to be printed are specifically analyzed by the data analysis system of the above-mentioned 3D printing device. How to analyze is a relatively mature technology of the 3D printing device and will not be elaborated here.

[0056] In this embodiment, in the above step S2 , the print head 10 can also move in the horizontal X and Y directions, so that the print head 10 can be easily moved in the horizontal direction, thereby increasing its flexibility in printing the prefabricated building components 40 .

[0057] In the present embodiment, in the above-mentioned step S4, a plurality of push plates 20 are arranged, and the plurality of push plates 20 are arranged in a vertical direction and move in the same direction, so that the print head 10 can print the prefabricated building components 40 layer by layer one by one, thereby effectively avoiding that the prefabricated building components 40 (such as walls) printed as a whole are too large, resulting in the inner surface of the prefabricated building components 40 not being well combined with the steel skeleton and the outer surface not being easy to smooth.

[0058] In this embodiment, the steps of printing the prefabricated building components 40 layer by layer include the following:

[0059] Step a, printing the lower prefabricated building component 40: adjusting the print head 10 to move to a first set position, the print head 10 prints the lower prefabricated building component 40, the lower prefabricated building component 40 is supported by the casting base plate, and then the lower prefabricated building component 40 is pushed by the lower push plate 20 to be combined with the steel frame 30 and the outer surface of the lower prefabricated building component 40 is flattened by the lower push plate 20;

[0060] Step b, printing the upper prefabricated building component 40: the print head 10 is adjusted to move to the second set position, and the print head 10 prints the upper prefabricated building component 40, which is supported by the upper surface of the lower push plate 20 in step a, and then the upper push plate 20 pushes the upper prefabricated building component 40 to be combined with the steel frame 30 and the upper push plate 20 flattens the outer surface of the upper prefabricated building component 40. By analogy, steps a and b are repeated to achieve multi-layer printing of prefabricated building components 40.

[0061] Of course, the casting base plate of the steel skeleton 30 , the upper end surfaces of the upper push plate 20 and the lower push plate 20 can all be set to smooth planes, which can facilitate the movement of the prefabricated building components 40 .

[0062] Under the premise that no conflict occurs, those skilled in the art may freely combine and superimpose the above-mentioned additional technical features.

[0063] The above description is only a preferred implementation mode of the present invention. Any technical solution that achieves the purpose of the present invention by substantially the same means belongs to the protection scope of the present invention.
