The invention provides a three-section type steel-concrete composite beam and a construction method thereof, and belongs to the field of fabricated buildings, the three-section type steel-concrete composite beam structurally comprises a middle beam and two rectangular pipe end beams, the two rectangular pipe end beams are located at the two ends of the middle beam respectively, and the rectangular pipe end beams are fixed to structural columns and connected to the ends of the middle beam; an end beam cavity is formed in the rectangular pipe end beam, compressive concrete is poured on at least the portion, in the rectangular pipe end beam, of the bottom plate, and the compressive concrete and the bottom plate form a bending moment compressive structure with the beam ends jointly pressed. The rectangular pipe end beam is pressed together with the steel beam through concrete, so that the steel consumption of the rectangular pipe end beam is greatly reduced, and the cost of the steel beam is saved.
本发明提供一种三段式钢‑混凝土组合梁及其施工方法，属于装配式建筑领域，其结构包括中间梁和两根矩形管端梁，两根矩形管端梁分别位于中间梁的两端，矩形管端梁固定于结构柱并连接于中间梁的端部；矩形管端梁内部形成有端梁空腔，至少矩形管端梁内部的底板上浇筑有抗压混凝土，抗压混凝土与底板形成梁端共同受压的弯矩抗压结构。矩形管端梁采用混凝土与钢梁共同受压，大幅减少了矩形管端梁的用钢量，节省钢梁成本。
