Assembly type hyperbolic steel corrugated plate shell, plate shell concrete arch bridge and construction method of assembly type hyperbolic steel corrugated plate shell
The invention relates to an assembly type hyperbolic steel corrugated plate shell. The plate shell is a spliced hyperbolic steel corrugated plate shell unit which is formed by bending and rolling a plane steel corrugated plate for multiple times and has a three-dimensional space bent shell surface, wherein the multi-time bending and rolling processing specifically comprises the following steps of performing transverse upward rolling and arching on a planar steel corrugated plate to form a large arc arch wave, and then processing and bending along the longitudinal direction to form a hyperbolic steel corrugated plate shell unit which has the same curvature as an arch ring and has two-way bending; arranging plate teeth which are bent outwards and upwards, are vertical and are used for transverse splicing on the two sides of each hyperbolic steel corrugated plate shell unit; and forming plate tooth bolt holes in the plate teeth at intervals of 20-40cm. According to the plate shell, shell space stress is achieved to the maximum extent through two-way bending, the assembled and spliced arch ring steel shell steel bar arch frame has high rigidity and deformation resistance, bridge support-free construction or simple fulcrum bent frame supporting construction can be achieved, and the construction period can be greatly shortened.
本发明涉及一种装配式双曲钢波纹板壳，板壳为采用一平面钢波纹板经多次弯曲轧制加工后使之具有三维空间弯曲壳面的可拼接的双曲钢波纹板壳单元；其中，多次弯曲轧制加工具体为：平面钢波纹板经横向向上轧制拱弯先形成大的圆弧拱波后，再沿纵向加工弯曲使之形成与拱圈曲率相同的具有双向弯曲的双曲钢波纹板壳单元；双曲钢波纹板壳单元的两侧设有向外向上弯曲且直立的用于横向拼接的板齿；板齿上每隔20‑40cm设置一板齿栓孔。该板壳通过双向弯曲最大限度地使其实现了壳体空间受力，其装配拼接到合拢后的拱圈钢壳钢筋拱架具有较大的刚度和抗变形能力，且可实现桥梁无支架施工或简单支点排架支承施工，可大大缩短建设工期。
