DETAILED DESCRIPTION OF THE INVENTION

(6) The present invention will be further described below in connection with the following embodiments. FIG. 1 is a cross-section structural schematic diagram of a horizontal section of a first embodiment. FIG. 1 depicts a 3D printed and combined building Wallboard 100, including external decorative plate 7, 3D printed external wallboard 1, cement concrete layer 9, 3D printed internal wallboard 2, internal decorative plate 8, and structural reinforcement component 10. Structural reinforcement component 10 includes a plurality of vertical steel reinforcements 5, and a plurality of horizontal steel reinforcements 11 continuously bent in a convex-concave way along the lengthwise direction of wallboard 100. In this embodiment, horizontal steel reinforcements 3 are arranged in a forward way, and horizontal steel reinforcements 4 are arranged in a reverse way. Horizontal steel reinforcements 3 and horizontal steel reinforcements 4 also are arranged in a staggered way with a preselected spacing of, for example and without limitation, one vertical steel reinforcement. Horizontal steel reinforcements 11 are evenly distributed with a preselected interval along the height of the wallboard in a way of one horizontal steel reinforcement 3 being arranged in a forward way and the other horizontal steel reinforcement 4 being arranged in a reverse way. The convex edge and the concave edge, of each horizontal steel reinforcement 3, 4, can be respectively located in the wallboard of the 3D printed external wallboard 1 and the wallboard of the 3D printed internal wallboard 2. Plurality of vertical steel reinforcements 5 can be located in the wallboard of the 3D printed external wallboard 1 and the wallboard of the 3D printed internal wallboard 2, and fixed at inner folding angles of horizontal steel reinforcements 11. External decorative plate 7 can be fixed on the 3D printed external wallboard 1. Internal decorative plate 8 can be fixed on the 3D printed internal wallboard 2. The space between the 3D printed external wallboard and the 3D printed internal wallboard is filled with the cement concrete layer 9.

(7) FIG. 2 is a horizontal-section structural schematic diagram of a second embodiment of 3D printed and combined building wallboard 200. Wallboard 200 may contain elements described with respect to wallboard 100 of FIG. 1. However, a thermal insulation layer 6 can be arranged between the external decorative plate 7 and the 3D printed external wallboard 1.

(8) FIG. 3 is a horizontal-section structural schematic diagram of a third embodiment of 3D printed and combined building wallboard 300. Wallboard 300 may contain elements described with respect to wallboard 200 of the embodiment of FIG. 2. However, a thermal insulation layer 15 may be arranged between the 3D printed external wallboard 1 and the cement concrete layer 9. Similarly, if a thermal insulation layer needs to be added to the internal wallboard 2, thermal insulation layer may be arranged in the same way as thermal insulation layer 15.

(9) The present invention is described above with reference to the drawings and the embodiments, which are not intended to be limiting. Those skilled in the art can make adjustments according to the actual needs and various variants or modifications made within the scope of appended claims, which shall fall within the scope of protection.

INDUSTRIAL APPLICABILITY

(10) The present invention has industrial applicability in the building/construction industry. An advantage is that any wallboard with a complicated structure can be printed through 3D printing technology, with thermal insulation layers and internal and external decorative layers also being constructed, in a standard plant, thus producing an integrated and modular wallboard, reducing construction components in a construction site, simplifying construction procedures, improving the working efficiency, saving time, material and labor and reducing the construction cost.
