Some novel features pertain to a floor coupling structure that includes a first portion, a second portion extending from a first end of the first portion, the second portion for coupling to a first plank portion of a floor plank; and a third portion extending from a second end of the first portion, the third portion for coupling to a second plank portion of the floor plank. In some implementations, the first portion, the second portion and the third portion are a single piece. In some implementations, the floor coupling structure further includes a side protrusion and side slot, the side slot configured to couple to another protrusion of a first coupling structure, the side protrusion configured to coupled to another side slot of a second coupling structure. In some implementations, the second portion is a first coupling portion and the third portion is a second coupling portion. |
