Fabricated steel-concrete composite beam structure connected by scissor-shaped steel plates and high-strength bolts
The invention relates to a fabricated steel-concrete composite beam structure connected by scissor-shaped steel plates and high-strength bolts, which comprises a steel beam, a precast concrete plate and the scissor-shaped steel plates, the steel beam, the precast concrete plate and the scissor-shaped steel plates are fixedly connected through high-strength bolt connecting pieces, a first positioning hole is formed in the precast concrete plate, and a second positioning hole is formed in the shear-shaped steel plates. Second positioning holes are formed in the steel beam, the scissor-shaped steel plate comprises a first steel plate and a second steel plate which are hinged to each other, third positioning holes are formed in the tail portions of the two ends of the first steel plate and the tail portions of the two ends of the second steel plate, and the steel beam, the prefabricated concrete plate and the scissor-shaped steel plate are connected and fixed through high-strength bolts. The contact area of the high-strength bolts and the upper portion of the concrete slab is increased, and the risk that the upper portion of the concrete slab is crushed is reduced; the application range of the assembly is expanded; recycling and reutilization of structural members are increased, resources are greatly saved, and the structure has a positive effect on prolonging the service life of the structure.
本发明涉及一种采用剪刀型钢板加高强螺栓连接的装配式钢混组合梁结构，包括钢梁、预制混凝土板和剪刀型钢板，所述钢梁、预制混凝土板和剪刀型钢板通过高强螺栓连接件固定连接，所述预制混凝土板上设置有第一定位孔，所述钢梁上设置有第二定位孔，所述剪刀型钢板包括相互铰接的第一钢板和第二钢板，所述第一钢板和第二钢板的两端尾部设置有第三定位孔，所述钢梁、预制混凝土板和剪刀型钢板通过高强螺栓连接固定。本发明增大了高强螺栓与混凝土板上部的接触面积，减小了混凝土板上部被压碎的风险；扩大了组件的适用范围；增加了结构构件的回收及重复利用，大大节约了资源，对延长结构的使用寿命具有积极的作用。
