Prefabricated assembly type steel-concrete composite structure bridge deck slab, joint structure and bridge
The invention discloses a prefabricated assembly type steel-concrete composite structure bridge deck, first stress ribs which extend in a first direction and are arranged in pairs in a third direction are arranged in the bridge deck, and the first stress ribs arranged in pairs in the third direction are divided into upper-layer stress ribs close to the top of the bridge deck and lower-layer stress ribs close to the bottom of the bridge deck. The first direction is different from the third direction; the bridge deck meets # imgabs0 #, and due to the fact that the tensile contribution degree of the high-performance concrete is considered, the tensile capacity of the steel bars and the tensile capacity of the high-performance concrete can be calculated through the formula, the height of the bridge deck is controlled, the dead weight of the bridge deck is reduced, the stress condition of the longitudinal and transverse beam assembly is improved, and the service life of the bridge deck is prolonged. And particularly, the overall anti-seismic property of the bridge is improved, which is of great significance to mountainous bridges. In addition, the invention further discloses a joint structure and a bridge.
本发明公开一种预制装配式钢混组合结构桥面板，桥面板中设有朝第一方向延伸、且朝第三方向成对设置的第一受力筋，沿第三方向成对设置的第一受力筋分为靠近桥面板顶部的上层受力筋，以及靠近桥面板底部的下层受力筋，第一方向和第三方向不同；桥面板满足：#imgabs0#如此，由于考虑了高性能混凝土的抗拉贡献度，故通过上述公式可以计算出钢筋的抗拉能力与高性能混凝土的抗拉能力，进而控制桥面板的高度，减少了桥面板自重，改善了纵横梁组件的受力情况，尤其提高了桥梁整体的抗震性能，这对于山区桥梁意义重大。此外，本发明还公开了一种接缝结构及桥梁。
