Detachable buckling-restrained supporting device and mounting method

LI YA / CAI WEI

The invention relates to a detachable buckling-restrained supporting device and an installation method. The detachable buckling-restrained supporting device comprises a supporting device body, a steel yoke plate, a double-T-shaped locking opening and a steel cylinder body structure. The supporting device comprises a supporting plate surface, a supporting reinforcing rib web plate, a supporting reinforcing rib arc-shaped wing plate, a cushion block, a bolt, a spring and an anchoring plate; the steel yoke plate comprises a steel yoke plate surface, a steel yoke plate reinforcing rib web plate, a steel yoke plate reinforcing rib arc-shaped wing plate, an end reinforcing flitch plate and a vertical end plate. The supporting device can be rapidly assembled and installed, the temporary reinforcing and supporting effect on the steel yoke plate is achieved, buckling deformation or fatigue damage of the steel yoke plate surface under the adverse sea condition environment condition is avoided, and when the environment condition is good, the supporting device can be conveniently dismantled; compared with a conventional scheme, the reinforced end structure with the double T-shaped locking openings and the steel yoke plates can greatly improve the local strength of the structure, the locking openings are prevented from being damaged by too large tension, and the overall rigidity, safety and reliability of the structure are overall improved.

本发明涉及一种可拆卸式防屈曲的支撑装置及安装方法，包括支撑装置、钢联板、双T形锁口、钢筒主体结构；支撑装置包括支撑板面、支撑加强肋腹板、支撑加强肋弧形翼板、垫块、螺栓、弹簧、锚固板；钢联板包括钢联板面、钢联板加强肋腹板、钢联板加强肋弧形翼板、端部加强贴板、竖向端板。本发明支撑装置可快速进行装配安装，对钢联板起到临时加固支撑作用，避免不利海况环境条件钢联板面屈曲变形或疲劳损伤破坏，在环境条件转好时，可方便拆除；焊接双T形锁口和钢联板加强型端部结构，相比常规方案可大大提高结构局部强度，避免拉力过大锁口破坏，本发明总体增加了结构的整体刚度和安全可靠性。
