Column-beam connecting assembly capable of being manually assembled and frame structure assembled thereby

A frame structure assembled by column-beam parts, the frame structure being formed by a plurality of connecting columns and a plurality of connecting beams connected between the plurality of connecting columns in a closed connection, wherein each connecting column includes a right-angle column for using at a first corner part of the frame structure, and a flat-angle column for using along a side or at a second corner part of the frame structure, said right-angle column and said flat-angle column are provided with at least one groove opening to column surfaces;

• a plurality of pairs of anchor slots are shaped on both sides of the groove, and the plurality of pairs of anchor slots are at a same height;
• a first maximum included angle between two connecting beams connected to each pair of anchor slots on the right-angle column is 90 degrees;
• a second maximum included angle between two connecting beams connected to each pair of anchor slots on a flat-angle column is 180 degrees;
• a plurality of mounting part for snapping into the plurality of pairs of anchor slots are shaped on both sides of each connecting beam;
• a plurality of half T-shaped jointing heads are provided on each outer end of said plurality of mounting parts for connecting to the arc channel;
• said plurality of half T-shaped jointing heads are either in a shape of a column head matching the arc channel, or in a shape of a hook head with a width less than a width of the groove;
• and at least one connecting beam is formed with a jointing head in the shape of the hook head on one half of an outer side of each mounting part.
