[0002] In the history of modern historical architectural art, mosaics have always been the finishing touch of buildings. Any part of a building that uses mosaics and mosaic puzzles is generally an important space in the building. In the renovation of historical buildings, it is difficult to control the construction quality of mosaics because of the small size of each piece and the various layout forms.

[0003] Conventional mosaic paving construction has multiple processes, among which the mosaic paving process is particularly important. The mosaic paving process should be started before the cement slurry has initially set. When paving the mosaic, the back of the mosaic should be clean and it should be done from the inside to the outside along the control line. When paving, turn up one side of the paper to expose the mosaic so as to align with the control line. Then immediately pave the mosaic (paper face up) and flatten the paper surface by hand, pat it with a clapper, so that the cement slurry penetrates into the seam of the mosaic until the mosaic seam watermark appears on the paper. In the actual construction process, due to the small size of mosaic particles, some mosaic small particles are only about 2cm, and the arrangement forms and patterns are diverse, when paving a large area, the labor cost is high and the construction quality control is difficult.

[0038] See also Figure 1 , Figure 2 and Figure 5 In some optional embodiments, the present application provides a mold for repairing mosaics of historical buildings, comprising a box body 1, a plurality of first partitions 2, and a plurality of second partitions 3. The plurality of first partitions 2 are installed in the box body 1 and arranged along the first direction. The first partition 2 is movably connected to the box body 1 so as to be suitable for moving along the first direction to adjust the spacing with adjacent first partitions 2. The first partition 2 is provided with a plurality of first connection structures spaced apart along the second direction; the second partition 3 is provided with a second connection structure detachably connected to the first connection structure. The plurality of second partitions 3 are distributed along the second direction, and the second partition 3 is suitable for connecting with the first connection structures at different positions in the second direction to adjust the spacing with adjacent second partitions 3.

[0039] Optionally, the first direction and the second direction are two directions perpendicular to each other in the horizontal direction. Specifically, in this embodiment, the box body 1 can be a square box, and the first direction, the length direction of the box body 1, the thickness direction of the first partition 2 and the length direction of the second partition 3 are the same, that is, the X direction in the drawings; the second direction, the width direction of the box body 1, the length direction of the first partition 2 and the thickness direction of the second partition 3 are the same, that is, the Y direction in the drawings; the height direction of the box body 1, the height direction of the first partition 2 and the height direction of the second partition 3 are the same, that is, the Z direction in the drawings.

[0040] Optionally, the box body 1 can be a square box with an upper opening, including a first side panel 11 and a second side panel 12 arranged opposite to each other, the first side panel 11 and the second side panel 12 are distributed along the second direction, the first side panel 11 is provided with a first slide groove, the second side panel 12 is provided with a second slide groove 121, and the two ends of the first partition plate 2 are respectively slidably matched with the first slide groove and the second slide groove 121; wherein, the box body 1 also includes a bottom plate and two third side panels 13 arranged opposite to each other, the two third side panels 13 are distributed along the first direction, the first side panel 11, the bottom plate and the second side panel 12 are connected to form a U-shaped frame with the opening facing upward, the two ends of the third side panel 13 are respectively connected to the first side panel 11 and the second side panel 12, wherein at least one of the third side panels 13 is detachably connected, specifically, the two ends of the third side panel 13 are respectively detachably connected to the first side panel 11 and the second side panel 12 by screws 14, so as to remove the third side panel 13. Furthermore, the first slide groove is arranged on the inner wall of the first side plate 11 and penetrates one end wall of the first side plate 11 along the first direction, the second slide groove 121 penetrates one end wall of the second side plate 12 along the first direction, the second slide groove 121 penetrates the inner and outer walls of the second side plate 12 along the second direction, one end of the first partition plate 2 is partially extended to form a first convex portion 23 that slides with the first slide groove, and the other end of the first partition plate 2 is partially extended to form a second convex portion 24 that slides with the second slide groove 121. The second convex portion 24 passes through the second slide groove 121 and is located on the outer side of the second side plate 12 and is locked with the second side plate 12 through the locking piece 6. This structural design makes it easy to disassemble and assemble the third side plate 13. After removing the third side plate 13, the first partition plate 2 can move along the first direction and slide out from the first slide groove and the second slide groove 121 to make room for other first partition plates 2 to move.

[0041] Optionally, scale lines may be provided at the top ends of the first side plate 11 , the second side plate 12 and the third side plate 13 to facilitate observation of the spacing between adjacent first partitions 2 and the spacing between adjacent second partitions 3 .

[0042] The mold for repairing mosaics of historical buildings in the above embodiment has a simple structure. The first partition plate 2 and the second partition plate 3 can be detachably connected and the spacing can be adjusted to adapt to the repair of mosaics of different sizes, thereby improving versatility and reducing costs.

[0043] See also Figures 1 to 4 In some optional embodiments, the first connection structure is a first card slot 21 with an upward opening, and the second connection structure is a second card slot 31 with a downward opening. The first partition 2 and the second partition 3 are positioned by the first card slot 21 and the second card slot 31, and when the first partition 2 and the second partition 3 are positioned, the top of the first partition 2 is flush with the top of the second partition 3. The width of the first card slot 21 and the second card slot 31 is smaller than the size of the mosaic particles, so as to prevent the mosaic particles from entering from one first sub-cavity to another first sub-cavity through the first card slot 21 and the second card slot 31 when repairing a mosaic of a larger size.

[0044] Optionally, the number of the first slots 21 provided on the first partition plate 2 can be set according to demand, as long as the structural strength of the first partition plate 2 can be ensured.

[0045] The mold for repairing mosaics of historical buildings in the above embodiment has the advantages that the first partition 2 is easy to move, the second partition 3 and the first partition 2 are reliably connected, and the disassembly and assembly operation is simple and convenient.

It can be understood that the minimum size of the mosaic particles is greater than the maximum size of the first groove 22, so that even if some of the first grooves 22 are not matched with the first protrusion 321 and exposed, the mosaic particles will not be embedded in the first groove 22.

[0047] Optionally, the splicing block 32 has two second side walls distributed along the first direction and opposite to each other, one of the second side walls is provided with a first protrusion 321, and the other second side wall is provided with a second groove 322, the second groove 322 extends along the height direction of the second partition 3 and passes through the top of the splicing block 32, and the first protrusion 321 of one splicing block 32 can be snap-fitted, positioned and assembled with the second groove 322 of the other splicing block 32.
