The invention relates to the technical field of repairing, dismantling or other work of original buildings, and discloses an attached tower crane for building transformation and a mounting method of the attached tower crane. The tower crane base is arranged on the side vertical face of a core tube of a built core tube steel structure building and connected with a floor steel beam of a non-top layer of the building into a whole, and a tower body upwards penetrates through at least two floors and then extends out of a roof. The tower crane base is a rigid square box, the floor steel beam penetrates through the bottom of the square box, and the square box is fixedly connected with the peripheral steel column of the core tube through a plurality of plane trusses; reinforcing connecting rods connected with the core tube internal steel columns are arranged at the connecting positions of the core tube peripheral steel columns and the tops of the left side and the right side of the truss box. According to the tower crane, the base of the tower crane is arranged on the high-rise floor and then connected with the core tube to increase the maximum hoisting weight, the tower body is low, damage to a building is small, and cost is low. Meanwhile, the area needing to be avoided below the suspension arm is small, the tower body does not need to damage the elevator shaft, and residents are allowed to live normally during construction.
本发明涉及原有建筑物的修理,拆除或其他工作技术领域,公开了一种用于建筑改造的附着式塔吊及其安装方法。塔吊底座设置在已建成的核心筒钢结构建筑的核心筒侧立面上并与建筑非顶层的楼面钢梁连为一体,塔身向上穿透至少两层楼板后伸到楼顶外;塔吊底座为刚性的方箱,楼面钢梁穿设在方箱底部,方箱通过多个平面桁架与核心筒外周钢柱固定连接;核心筒外周钢柱与桁架箱左右两侧顶部的连接位置设置有与核心筒内部钢柱连接的加固连杆。本发明中,通过把塔吊的底座设置在高层楼板上,然后与核心筒连接以增加最大吊重,塔身低且对建筑造成的破坏小,成本低。同时,吊臂下方需要避开的区域小,且塔身不需要破坏电梯井,允许住户在施工时正常居住。
