The outer surface of the wall panel frame 4 is provided with a plurality of wall panel vertical reinforcing ribs 42 at intervals along its height direction, and the inner surface is provided with a plurality of wall panel transverse reinforcing ribs 43 along its length direction, so as to ensure the overall strength of the wall panel; in the implementation process, the number of the wall panel vertical reinforcing ribs 42 and the wall panel transverse reinforcing ribs 43 is adaptively selected according to the length and strength requirements. In order to ensure the strength of the upper part of the wall panel frame 4, a plurality of wall panel frame support pipes 44 are provided at intervals in the upper part of the wall panel frame 4.

[0031] In this embodiment, after the crossbeam 2 is suspended, the integrated gantry frame 1 is symmetrical in front and back, left and right directions, so as to ensure the working effect while having enough space for installing and repairing the printer head.

[0032] The wall panel frame 4 is connected by a plurality of wall panel frame connecting pipes 5, and is located at the left and right edges (from Figure 1 Two universal wheels 8 are provided on the two wall panel frame connecting pipes 5 (see perspective), which are used to facilitate the movement of the assembled frame and ensure the stability of the frame.
