Ultrahigh-toughness combined bridge deck formed by assembling and connecting angle steel and profiled steel sheets
The invention discloses an ultrahigh-toughness combined bridge deck formed by assembling and connecting angle steel and profiled steel sheets. The ultrahigh-toughness combined bridge deck is composed of the profiled steel sheets, the angle steel, round steel bars, high-strength bolts and ultrahigh-toughness concrete. Bolt holes are formed in the upper flange of the profiled steel sheet and the long limbs of the angle steel at equal intervals, round holes are formed in the short limbs of the angle steel at equal intervals, high-strength bolts penetrate through the bolt holes to connect the profiled steel sheet and the angle steel, then round steel bars penetrate through the round holes, and the bridge deck steel framework is formed. The ultrahigh-toughness concrete is poured on the bridge deck steel framework to play a role in protecting the bridge deck steel framework. In the invention, the bridge deck steel skeleton is prefabricated in advance by a factory, the prefabrication assembly degree is high, and the fatigue performance of the structure is improved while the construction complexity and the material cost are reduced. The ultra-high-toughness concrete can ensure that no or only small cracks of 100 microns or below are generated, the use requirement of a reinforcing mesh is effectively avoided, and the toughness and durability of the structure are improved.
本发明公开了一种角钢和压型钢板装配连接的超高韧性组合桥面板，由压型钢板、角钢、圆钢棒、高强螺栓、超高韧性混凝土组成。在压型钢板上翼缘和角钢长肢上等间距开设螺栓孔，在角钢短肢上等间距开设圆孔，将高强螺栓穿过螺栓孔连接压型钢板和角钢后再将圆钢棒穿过圆孔，成为桥面钢骨架。超高韧性混凝土浇筑在桥面钢骨架上，起到保护桥面钢骨架的作用。在本发明中，桥面钢骨架由工厂提前预制，预制装配化程度高，在降低施工复杂度和材料成本的同时提升了结构的疲劳性能。超高韧性混凝土可保证不产生或仅产生100微米以下的微小裂缝，有效规避了钢筋网的使用需求，提升了结构的韧性和耐久性。
