Abstract: A platform-type shelf includes at least two lengthways lattice beams, at least two transverse lattice beams, at least two lengthways frame beams, and at least two transverse frame beams. Each lattice beam defines downward engaging grooves and upward engaging grooves. The lengthways lattice beams and the transverse lattice beams can be vertically snapped one other via a weaving technique. Each end of the frame beam has an outer tenon and an inner tenon, and the outer tenons of the two ends of the frame beam and the inner tenons thereof respectively have contrary locations in up-down direction. The outer tenons and the inner tenons of two adjacent frame beams are respectively engaged in a fastening manner. Thereby, the lattice-like platform-type shelf can be formed so as to entirely enhance its connecting force and supporting force, and to facilitate various derivative applications thereof.
