The invention relates to a dedicated waist beam for a bus framework. The waist beam is arranged on the left side and the right side of the bus framework horizontally. The dedicated waist beam for the bus framework is characterized in that one side, arranged on the outer side of a bus body, of the waist beam is sequentially provided with a first outer step surface, a second outer step surface and a third outer step surface from top to bottom, wherein the first outer step surface and the second outer step surface extend outwards, and the third outer step surface is concaved inwards. The side, arranged on the inner side of the bus body, of the waist beam is sequentially provided with a first inner step surface and a second inner step surface, wherein the first inner step surface is ejected inwards, and the second inner step surface is concaved outwards. The dedicated waist beam has the advantages that according to the technical sachem, due to an outer connecting piece installing area A, an outer connecting piece installing area B, an inner connecting piece installing area A and an inner connecting piece installing area B, positioning is convenient to carry out during riveting, the manpower labor intensity is saved, due to a glass installing area, during glass installing, the condition of the glass dislocation due to the glass sliding can be avoided, and therefore the installing efficiency is improved.
