The invention discloses an end plate connection type prefabricated reinforced concrete beam. The beam is characterized in that longitudinal steel bars are arranged on an upper flange and a lower flange of a reinforced concrete main body, a sealing plate is connected to the end of the reinforced concrete main body, studs are welded to the inner side of the sealing plate, and the studs are solidified in concrete of the reinforced concrete main body; the outer side of the sealing plate is welded with the inner end of H-shaped steel, and the outer end of the H-shaped steel is welded with an end plate; shear force at the end of the reinforced concrete body is transmitted to the H-shaped steel through the studs on the sealing plate and then transmitted to a column through the end plate, and bending moment of a concrete beam section is transmitted to the H-shaped steel through the longitudinal bars; stiffening ribs are arranged between the flanges and a web of the H-shaped steel; and the longitudinal steel bars penetrate through holes in the upper flange and the lower flange of the H-shaped steel and then are bent and attached to the stiffening ribs to form anchoring. The invention further discloses a design method of the prefabricated reinforced concrete beam. According to the beam and the method, the defects that a prefabricated reinforced concrete structure is complex in connectionjoint and poor in reliability are overcome.
端板连接型装配式预制钢筋混凝土梁，钢筋混凝土主体的上下翼缘上设有纵向钢筋，钢筋混凝土主体的端部连接一块封板，封板的内侧焊有栓钉，栓钉固结在钢筋混凝土主体的混凝土内；封板的外侧与H型钢的内端焊接，H型钢的外端与端板焊接；钢筋混凝土主体端部的剪力通过封板上的栓钉传给H型钢后再通过端板传给柱子，混凝土梁段的弯矩通过纵筋传给H型钢；H型钢的翼缘和腹板之间设有加劲肋；纵向钢筋穿过H型钢的上下翼缘的孔后弯折并贴在加劲肋上形成锚固。本发明还包括装配式预制钢筋混凝土梁的设计方法。本发明克服了装配式钢筋混凝土结构连接节点复杂、可靠性较差的缺点。
