Combinable floor plate

A combinable floor plate comprising:

• a first connection part formed on a first side face of the floor plate and having a tongue extending from the first side face, an upper cutout defined in a top face of the tongue, a lower cutout defined in a bottom face of the tongue and a recess defined in a bottom face defining the lower cutout to communicate with the lower cutout;
• a second connection part formed on a second side face of the floor plate opposite to the first connection part, the second connection part having a receiving space defined in the second side face of the floor plate to correspond to the tongue, a first slit defined in a side face defining the receiving space to communicate with the receiving space and a second slit defined in the side defining the receiving space to communicate with the receiving space;
• and
• a securing device including a base with a wall formed on a top face of the base to be received in the lower cutout and the recess of the first connection part of an adjacent floor plate and a substantially L-shaped baffle formed on a mediate portion of the top face of the base to be received in the receiving space and the first slit of the second connection part, wherein a side face opposite to and far away from the wall is received in the second slit of the second connection part, such that after securing elements are applied to extend through the base and into a first extension formed on the second side face of the floor plate between the first slit and the second slit and the tongue from adjacent floor plate is received in the receiving space with a second extension formed on top of the first extension of the second connection part received in the upper cutout and the wall received in the lower cutout and the recess of the first connection part of the adjacent floor plate, two floor plates are combined.
