The invention discloses a steel-concrete composite beam which comprises H-shaped steel, concrete and a reinforcing mesh disposed in the concrete, wherein the bottom of the concrete is clung with a bottom wing plate of the H-shaped steel; two side faces of the concrete are flush with edges of the bottom wing plate of the H-shaped steel; separation space is formed between the top of the concrete andthe top wing plate of the H-shaped steel; one section of a middle web of the H-shaped steel is embedded in the concrete, and the other section is located in the separation space; and multiple mutually isolated through holes used for passing of rebar are formed in the section, located in the separation space, of the middle web of the H-shaped steel. The steel-concrete composite beam disclosed by the invention has the beneficial effects that a building net height is saved; combined effects of the steel-concrete composite beam are enhanced; bearing force and rigidity of the steel-concrete composite beam are enhanced, so deflection of a horizontal structure can be controlled effectively, and comfort is enhanced; and problems of cracking of internal parting walls are reduced.
本发明公开了一种钢混组合梁，包括H型钢、混凝土、设于混凝土内的钢筋网，所述的混凝土底部与H型钢底部翼板贴紧，所述混凝土两侧面与H型钢底部翼板边缘平齐，所述混凝土顶部与H型钢顶部翼板之间设有间隔空间，所述的H型钢中部腹板一段埋设于混凝土内、另一段位于间隔内，所述的H型钢中部腹板位于间隔空间内的一段上设有多个相互隔离、可容钢筋穿过的通孔。本发明节约了建筑净高，同时也增加了钢‑混组合梁的组合效应，提高了钢‑混组合梁承载力和刚度，从而可以有效的控制水平结构的挠度，提高舒适性，并且减少内隔墙的开裂问题。
