The invention provides a three-section combined steel beam and combined frame beam-column structure, and belongs to the field of fabricated constructions.The three-section combined steel beam comprises a steel truss beam body, two solid-web steel beam sections and two splicing end plates, and the two solid-web steel beam sections are connected to the two ends of the steel truss beam body through the splicing end plates; the steel truss girder body comprises an upper chord member, a lower chord member and a middle web member, and the solid web steel girder section at least comprises an upper chord plate, a lower chord plate and a solid web plate. In a beam column structure, a frame beam is generally large in beam end bending moment and small in midspan bending moment, a combined steel beam can be designed in a segmented mode according to the stress characteristic of the frame beam, the combined steel beam adopts a solid web section with large rigidity and high bearing capacity at the beam end with large stress, and a steel truss with appropriate rigidity and matched bearing capacity is adopted in the middle section of the beam with small stress. Therefore, the economical efficiency is improved. And the middle section of the beam adopts the steel truss beam body, and a cavity formed by the truss facilitates the installation of pipelines, so that the overall floor height space is saved.
本发明提供了一种三段组合钢梁和组合框架梁柱结构，属于装配式建筑领域，其中三段组合钢梁包括钢桁架梁体、二实腹钢梁段和二拼接端板，二实腹钢梁段通过拼接端板连接于钢桁架梁体的两端；钢桁架梁体包括上弦杆、下弦杆和中间腹杆，实腹钢梁段至少包括上弦板、下弦板和实腹板。在梁柱结构中，框梁一般是梁端弯矩大，跨中弯矩小，组合钢梁可根据框梁的这一受力特点进行分段设计，组合钢梁在受力较大的梁端采用刚度较大、承载力较高的实腹截面，在受力较小的梁中间段采用刚度合适、承载力匹配的钢桁架，从而提高经济性。且梁中间段采用钢桁架梁体，桁架形成的空腔便于管线的安装，节省了整体的层高空间。
