Corner cut 13 on the floor carrier plate body 10 and corner cut 13 on the adjacent floor carrier plate body 10 can form the accommodation space, the accommodation space can be narrow down wide triangle-shaped structure, when the decorative surface layer at the bottom of the board, at first the accommodation space intussuseption that corner cut 13 formed is filled with sealing material and is made level, sealing material is like materials such as elastic cement mortar or wall mud, wait to dry the back and make the construction on next step of decorative surface again, this kind of construction mode can effectively prevent that the piece department at the bottom of the board from taking place the fracture, the problem of the decorative layer fracture at the bottom of the board that traditional piece way brought has been solved.

To further reduce the splice joint misalignment between two adjacent floor deck plates 10, referring to fig. 11 in conjunction with fig. 1, one way that can be achieved is that the end of the connector 20 extending beyond the floor deck plate 10 is fixedly connected to the adjacent floor deck plate 10 by a fastener 30. After the splicing of the two floor support plate bodies 10 is completed, one end of the connecting piece 20 extending out of the floor support plate body 10 is fixed on the adjacent floor support plate body 10 through the self-tapping screw, the self-tapping screw can be locked from top to bottom or locked from bottom to top, or two fasteners 30 can be arranged, one fastener 30 is locked from top to bottom, and the other fastener is locked from bottom to top, so that the problem of the staggered joint between the two adjacent floor support plate bodies 10 can be effectively solved, and the flatness of the bottom of a floor slab can be effectively improved.

Further, in order to reduce the joint misalignment between two adjacent floor support plate bodies 10, referring to fig. 12 and 13, it is still another achievable way that the anti-misalignment rabbet disassembly-free floor support plate further includes a fixing plate 50, and the fixing plate 50 is fixedly connected to the first surface, and spans the joint between two adjacent floor support plate bodies 10 to be connected with the adjacent floor support plate bodies 10.
