PBL composite stud steel-UHPC composite beam structure
The invention relates to the technical field of constructional engineering, and particularly discloses a PBL composite stud steel-UHPC composite beam structure which comprises a steel beam, a concrete plate, a steel plate and studs. The concrete slab is provided with a prefabricated groove; the steel plate is fixed on the top surface of the steel beam; the stud is welded on the steel plate, and a rubber sleeve is wrapped outside the stud; the concrete plate is carried on the top face of the steel beam, and the steel plate, the toggle pin and the rubber sleeve are all located in the prefabricated groove and form a composite shear key. Concrete is poured into the prefabricated grooves, so that the concrete slab and the composite shear keys are poured into a whole; according to the PBL composite stud steel-UHPC composite beam structure, the characteristics and advantages of the steel beams, the PBL shear keys, the studs and the UHPC materials can be exerted, so that a bridge has high spanning capacity, environment friendliness and timeliness, application and popularization are facilitated, and the potential fatigue problem of traditional welding studs can be solved.
本发明涉及建筑工程技术领域，具体公开一种PBL复合栓钉钢‑UHPC组合梁结构，包括钢梁、混凝土板、钢板和栓钉；所述混凝土板具有预制槽；所述钢板固定在所述钢梁的顶面；所述栓钉焊接在所述钢板上，且所述栓钉外包裹有橡胶套；所述混凝土板搭载在所述钢梁的顶面，且所述钢板、栓钉和橡胶套均位于所述预制槽内，所述钢板、栓钉和橡胶套构成复合剪力键；所述预制槽内浇筑有混凝土，以使所述混凝土板与复合剪力键浇筑成一体；该PBL复合栓钉钢‑UHPC组合梁结构能够发挥钢梁、PBL剪力键、栓钉、UHPC材料的特性及优点，使得桥梁具有较强的跨越能力、环保性和时效性，有利于推广使用，而且可以解决传统焊钉潜在的疲劳问题。
