The present invention provides an expandable and contractable type absorbing floor board utilized as an edge finishing material of a laminated floor board, an intermediate material between laminated floor boards, or an expansion/finishing profile of a door stud interface which partitions a space to effectively absorb an expansion and contraction ratio expanded or contracted in accordance to the changes in temperature and humidity of the constructed laminated floor boards, thereby minimizing deformation (defects) of a constructed state. The above object of the present invention can be achieved by the expandable and contractable type absorbing floor board industrially manufactured by extrusion molding, and has a structure whereby the upper and lower surfaces are mutually bonded by the upper and lower surface bonding members of soft PVC having elasticity with a predetermined space between neighboring rigid resin boards, and outermost rigid resin boards having a tongue-and-groove structure identical with a tongue-and-groove structure of the constructed laminated floor boards. |
