A combining floor panel is provided to improve connection between floor panels and withstand environmental change such as heat and moisture by making coupling shapes at top, bottom, right and left portions. A combining floor panel comprises a top portion(130), a bottom portion(140), a right portion(120), and a left portion(110). The top portion includes an upper end(131), a lower end(136), a protrusion(132), first and second protrusions(135,134), and a stepped protrusion groove(133). The protrusion forms between the upper end and the lower end. Both protrusions form under the protrusion. The stepped protrusion groove is located next to the second protrusion. The bottom portion includes an upper end(141), a lower end(143), a groove(142), first and second recesses(143a,143b), and a stepped protrusion(143c). The groove forms between the upper end and the lower end and receives the protrusion of the top portion. The first and second protrusions of the top portion fit to both recesses of the bottom portion. The stepped protrusion is inserted into the stepped protrusion groove. The left portion includes a protrusion(112) and a projection(112c). The protrusion forms between an upper end(111) and a lower end(113). The projection forms on the bottom surface of the protrusion. The right portion includes a groove(122) and a concave portion(123a). The groove of the right portion forms between an upper end(121) and a lower end(123) and receives the protrusion of the left portion. The concave portion forms on the lower end and fits to the projection. |
