Anti-cracking hollow floor structure

The invention discloses an anti-cracking hollow floor structure. The anti-cracking hollow floor structure comprises a main body plate, at least one bulge and one open groove which are mutually matched are formed in the two sides of the main body plate correspondingly, at least two protruding blocks are arranged on each of the upper surface and the lower surface of each bulge correspondingly, and concave grooves capable of containing the protruding blocks are formed in the inner wall of each open groove; and a waterproof layer is arranged on the main body plate, half-round-shaped through holes are formed in the main body plate. According to the anti-cracking hollow floor structure, multiple waterproofing measures are arranged, the waterproof sealing effect is good, structural connection is firm, the service life is long, and the problems that a traditional board material is not firm enough in connection and prone to generating water seepage cracking and deforming are solved. 本发明公开了种防开裂中空地板结构，该防开裂中空地板结构，包括主体板，所
