Cable-stayed anchoring construction process for cantilever slab of high-rise building
The invention discloses a cable-stayed anchoring construction process for a cantilever slab of a high-rise building. The cable-stayed anchoring construction process comprises the following steps: step 1, determining a cable-stayed anchoring support construction scheme for a large-area cantilever slab of the high-rise building; 2, a concrete structure of a floor where the outer bridging plate is located is constructed; 3, after the concrete strength of the outer bridging plate reaches 85% of the design strength; a through hole is pre-formed in the outer wall of the upper portion of an outer bridging piece for a common floor outer bridging piece, and a middle anchoring end opposite penetrating bolt is anchored at the position of the through hole; and profile steel transfer columns are installed at the positions, where vertical buried plates are preset on the top of the outer wall, of the roof outer bridging plates. According to the cable-stayed anchoring construction technology for the cantilever plate of the high-rise building, the original floor or roof serves as a tension anchoring end on one side in a symmetrical cable-stayed mode, the cantilever plate support is assembled on the other side, and a high-altitude cable-stayed anchoring structure which is reasonable in stress, safe, stable and capable of achieving the landscape effect is formed; and the construction difficulty of the outer edge cantilever plate of the large-area concrete structure of the high-rise building can be effectively solved.
本发明公开了一种高层建筑外挑板斜拉锚固施工工艺，包括以下步骤：步骤一：确定高层建筑大面积外挑板斜拉锚固支撑施工方案；步骤二：外挑板所在楼层混凝土结构施工；步骤三：待外挑板的混凝土强度达到设计强度85%后；对于普通楼层外挑板在外挑板上部外墙预设通孔，并在通孔位置锚固中间锚固端对穿螺栓；对于屋面外挑板在外墙顶部预设竖向埋板处安装型钢转接柱。本发明提供的高层建筑外挑板斜拉锚固施工工艺，利用对称斜拉方式在原有楼面或屋面作为一侧受拉锚固端，另一侧组装外挑板支架，形成受力合理、安全稳固兼具景观效果的高空斜拉锚固构造，可以有效解决高层建筑大面积混凝土结构外沿悬挑板的施工难点。
