Orthotropic steel bridge deck fatigue reinforcing body structure and construction method thereof
The invention relates to a bridge structure, in particular to an orthotropic steel bridge deck fatigue reinforcing body structure and a construction method thereof, the orthotropic steel bridge deck fatigue reinforcing body structure comprises a concrete layer on a bridge longitudinal rib, the concrete layer comprises a steel bar group, and the steel bar group comprises transverse steel bars and longitudinal steel bars which are stacked up and down; shearing force pin pieces welded on the steel top plate are arranged below the steel bar group, grooves are formed in the shearing force pin pieces, and the shearing force pin pieces extend along the direction of the transverse steel bars and are arranged along the extending direction of the longitudinal steel bars; the longitudinal steel barsare supported on the shear pin pieces, and the supporting joints are located on the portions, between every two adjacent grooves, of the shear pin pieces. After the shear pin pieces are welded to a full-bridge steel bridge deck, the reinforcing mesh is arranged on the shear pin pieces, the ultra-high-performance concrete structure layer is poured on the shear pin pieces, and the pure anisotropic steel bridge deck is converted into the combined bridge deck, so that the purposes of improving the local rigidity, reducing the stress amplitude and improving the fatigue performance are achieved.
本发明涉及桥梁结构，具体涉及一种正交异性钢桥面板疲劳加固体结构及其施工方法，正交异性钢桥面板疲劳加固体结构，包括桥梁纵肋上的混凝土层，该混凝土层包括钢筋组，钢筋组包括上下叠放的横向钢筋和纵向钢筋；钢筋组下方设置有焊接在钢顶板上的剪力销件，该剪力销件上开有凹槽，该剪力销件沿横向钢筋方向延伸，剪力销件沿纵向钢筋延伸方向排列；纵向钢筋支撑于剪力销件上，该支撑节点位于相邻的两个凹槽之间的剪力销件部分上。本发明在全桥钢桥面上焊接上述的剪力销件后，在其上布置钢筋网、浇筑超高性能混凝土结构层，将纯正交异性钢桥面板转化为组合桥面板，以实现提高局部刚度，降低应力幅，达到提高疲劳性能的目的。
