FLOOR UNDERLAY USED FOR A BASE FRAME

摘要

A floor underlay used for a base frame, comprising a face panel (1) having two parallel sides (2); the spacing between the two parallel sides (2) matching the width of a single floor (11) combined with same; hook-shaped protrusions (3) protruding toward the top of the face panel (1) being disposed at the two sides (2), the two hooks being oppositely arranged and able to snap-fit into the two grooves of the floor (11) combined therewith, the side walls of the floor (11) having grooves; the face panel (1) being also provided with screw through-holes (4). The floor underlay makes floor-laying simple and time-saving, and reduces the gap between floors.
