Assembled detachable steel-concrete-wood composite beam
The invention relates to an assembled detachable steel-concrete-wood composite beam which comprises a concrete plate, a reinforcing plate and a pair of wood beams, the end, facing the concrete plate, of the reinforcing plate is provided with a shear-resistant connecting part, the shear-resistant connecting part is embedded in the concrete plate, and the reinforcing plate is provided with a first surface and a second surface which are oppositely arranged in the thickness direction; the pair of wood beams are respectively connected with the first surface and the second surface of the reinforcing plate; the wood beam comprises a first end and a second end which extend in the first direction of the reinforcing plate, the first end or the second end extends to the end, away from the concrete plate, of the reinforcing plate, and the first direction is perpendicular to the thickness direction of the reinforcing plate. According to the steel-concrete-wood composite beam, through reasonable design, the reinforcing plate is arranged between the pair of wood beams, under the normal condition, the reinforcing plate and the wood beams are both located in a tension area, the centroid heights are similar, the requirement for shear-resistant connection between the reinforcing plate and the wood beams is low, and therefore the steel-concrete-wood composite beam has good overall working performance; the reinforcing plate not only improves the flexural capacity and flexural rigidity of the composite beam, but also improves the ductility of the composite beam.
本发明涉及一种装配可拆卸式钢‑混凝土‑木组合梁，包括混凝土板、加固板和一对木梁，加固板朝向混凝土板的一端设置有抗剪连接部，抗剪连接部嵌设于混凝土板中，加固板具有沿厚度方向相对设置的第一表面和第二表面；一对木梁分别连接加固板的第一表面和第二表面；木梁包括沿着加固板的第一方向延伸布设的第一端和第二端，第一端或第二端延伸至加固板背离混凝土板的一端，第一方向与加固板的厚度方向垂直。本发明通过合理设计，将加固板设置于一对木梁之间，通常情况下加固板与木梁均处于受拉区，形心高度相近，对两者之间的抗剪连接要求低，因此钢‑混凝土‑木组合梁具有良好的整体工作性能；加固板不仅提高了组合梁的抗弯承载力和抗弯刚度，也改善了组合梁的延性。
