Full assembly type NHNR shear connection steel-concrete composite beam
The invention discloses a full assembly type NHNR shear connection steel-concrete composite beam which comprises a steel beam and a prefabricated concrete bridge deck, the prefabricated concrete bridge deck extends downwards and is provided with shear nails in an embedded mode, the steel beam is provided with shear holes corresponding to the shear nails, the prefabricated concrete bridge deck is arranged on the steel beam, and the shear nails are inserted into the shear holes; the prefabricated bridge deck is fixedly connected with the steel beam near the end joint surface of the prefabricated bridge deck. The mechanical connection principle of nail-hole nesting and single-face rivet operation on the bridge floor is adopted, a traditional civil structure connection mode through cast-in-place concrete or on-site welding is replaced, composite bridge structure prefabrication-assembly type industrial construction in real significance is achieved, the on-site construction period is remarkably shortened, the construction land for bridge construction is reduced, the exploiting amount of gravel is reduced, the recycling rate of materials is increased by 30%, the bridge construction cost can be obviously reduced through batch industrial production, and remarkable technical, economic, environment-friendly and social benefits are achieved.
本发明公开了一种全装配式NHNR剪力连接的钢‑砼组合梁，包括钢梁和预制砼桥道板，预制砼桥道板向下延伸预埋有剪力钉，钢梁与所述剪力钉对应设有剪力孔，所述预制砼桥道板置于所述钢梁上且剪力钉插入所述剪力孔；在预制桥道板的端接缝面附近，预制桥道板与钢梁之间呈固定连接；本发明采用钉‑孔嵌套和在桥面操作单面铆钉的机械连接原理，取代了通过现浇混凝土或现场施焊的土木结构传统连接方式，实现了真实意义的组合桥梁结构预制‑装配式工业化建造，显著缩短了现场建设工期，减少了桥梁建设施工用地，降低了砂石开采量，提高了材料可回收利用率30％，批量化工业生产可明显降低桥梁建设费用，具有显著的技术、经济、环保和社会效益。
