Novel combined shear-resistant bolt structure of steel-concrete combined beam
The invention relates to a novel steel-concrete composite beam combined shear-resistant bolt structure which comprises a high-strength bolt, a rubber layer sleeve, a sleeve bolt and a supporting steel beam, a screw of the high-strength bolt comprises a smooth section at the upper end and a threaded section at the lower end, the rubber layer sleeve is arranged on the smooth section of the high-strength bolt in a sleeving mode, and threads are arranged outside the sleeve bolt. The high-strength bolts are arranged in the sleeve bolts, first reserved holes are formed in the supporting steel beams, and the sleeve bolts penetrate through the first reserved holes to be fixedly arranged on the supporting steel beams. According to the combined bolt structure adopting the sleeve bolt and the high-strength bolt with the rubber layer, the bonding between a component and concrete is effectively improved, the overall ductility of the component is improved, and the concrete is effectively prevented from being crushed when being stressed.
本发明涉及一种新型钢混组合梁组合抗剪螺栓结构，包括高强螺栓、橡胶层套筒、套筒螺栓和支撑钢梁，所述高强螺栓的螺杆包括上端的光滑段和下端的螺纹段，所述橡胶层套筒套设在高强螺栓的光滑段上，所述套筒螺栓外部设置螺纹，所述高强螺栓设置在套筒螺栓内，所述支撑钢梁上设置第一预留孔，所述套筒螺栓穿过第一预留孔固定设置在支撑钢梁上。本发明有效增加构件与混凝土之间的粘结，增加构件整体延性，有效保护混凝土在受力时不被压碎的采用套筒螺栓加带橡胶层高强螺栓的组合式螺栓结构。
