Abstract: The present disclosure discloses a modified calcium silicate board, and belongs to the technical field of floors and decorative boards. A modification method comprises steps of: dipping a calcium silicate board in a silicon dioxide solution with a solid content of 95% or more, completely absorbing the silicon dioxide solution until the calcium silicate board is saturated, and drying the dipped calcium silicate board; and carrying out sizing hardening on any surface of the modified calcium silicate board to obtain the calcium silicate board, so as to enable the triamine impregnated paper to be directly laminated with the calcium silicate board in a hot-pressing manner, and enable the surface bonding strength to reach 1 MPa; wood veneers, fireproof plates and other materials are subjected to coldbonding, the peeling strength of the product meets the requirements, and the practicability of the calcium silicate board is effectively improved.

Abstract: The present disclosure discloses a quickly dismantlable floor member and a spliced floor, to solve the technical problem that the conventional floor members cannot be dismantled conveniently for repairing and replacement. The quickly dismantlable floor member is of a tetragon shape, a lateral face of a first side of the quickly dismantlable floor member is provided with an automatic latch, the automatic latch comprises a locking head, the locking head is retractable, and the locking head is able to, after the quickly dismantlable floor member is installed, join with an neighboring conventional floor member. The spliced floor employs three or more quickly dismantlable floor members.
