Prestress cable-stayed large-cantilever glass landscape platform and construction method thereof
The invention relates to the field of prestressed steel structures, and discloses a prestressed cable-stayed large cantilever glass landscape platform and a construction method thereof, the landscape platform comprises a cable bent tower, a cantilever platform, a tourist platform, a stay cable, a balance back cable, a wind-resistant cable and a tuned mass damper. The two sides of the overhanging platform are stayed through the stay cables, the overhanging platform is hung on the cable bent tower to achieve large overhanging, meanwhile, the balance back cables anchored to the tourist platform are arranged on the back face of the cable bent tower, and parallel double cables and double anchor points which are close to each other are adopted at the stayed positions of the stay cables and the balance back cables in the longitudinal direction of the platform. The progressive collapse resistance of the structure is improved, and subsequent cable replacement is facilitated; wind-resistant cables are arranged on the two sides of the cantilever platform, the transverse rigidity of the cantilever platform is increased, and the wind-resistant capacity of the cantilever platform is improved; the tuned mass damper mounted at the end part of the cantilever platform can control the acceleration of human-induced vibration; and the main stress truss of the cantilever platform is connected by adopting segmented integral hoisting and large-diameter pin shafts, so that a large amount of high-altitude welding operation is avoided, and the construction is safe and reliable.
本发明涉及属于预应力钢结构领域，公开了一种预应力斜拉大悬挑玻璃景观平台及其施工方法，所述景观平台包括索塔、悬挑平台、游客平台、斜拉索、平衡背索、抗风索和调谐质量阻尼器。本发明通过斜拉索斜拉悬挑平台两侧将其吊挂在索塔上来实现大悬挑，同时索塔背面设置锚固在游客平台上的平衡背索，且斜拉索及平衡背索沿平台纵向每个斜拉处均采用距离相近的平行双索和双锚点，既改善结构抗连续倒塌能力又方便后续换索；悬挑平台两侧设置的抗风索，增加其横向刚度，提高其抗风能力；悬挑平台端部安装的调谐质量阻尼器，能控制人致振动加速度大小；悬挑平台的主受力桁架采用分段整体吊装和大直径销轴连接，避免了大量高空焊接作业，施工安全可靠。
