The invention discloses a breakage-proof device for building material transportation. The breakage-proof device comprises a plurality of box body housings, wherein each box body housing is of a rectangular structure, a plurality of transverse cushion interlayers and longitudinal soft interlayers are arranged in the box body housings, the transverse cushion interlayers are horizontally placed, thelongitudinal soft interlayers are vertically placed, and the transverse cushion interlayers and the longitudinal soft interlayers are intersected with each other so as to form a plurality of tile containing cavities; the width of each box body housing adapts to the size of tiles of general specifications, and the plurality of box body housings are spliced in the width direction so as to contain large tiles. According to the breakage-proof device, the transverse cushion interlayers and the longitudinal soft interlayers are intersected so as to form the tile containing cavities in the box body housings, so that the tiles are tidily arranged in the tile containing cavities. The tile containing cavities in a single box body housing adapt to the size of the tiles of general specifications, andwhen the large tiles need to be shipped, two or a plurality of box body housings are spliced into transportation equipment enough to transport the tiles of the corresponding size.
