Summary:The invention discloses a rectangular concrete filled beam with a hollow steel tube. Concrete is poured between a rectangular outer steel tube and an inner sleeve which are coaxial, and the inner sleeve is hollow. The rectangular concrete filled beam with the hollow steel tube has the advantages that: (1) due to the 'look around' effect of the rectangular outer steel tube and the inner sleeve, the compressive strength of the concrete of the beam is obviously improved; (2) the section of the beam is small, the deadweight of the beam is light, and the indoor useful space is large; and (3) cables can be laid in the inner sleeve.
