The invention belongs to the technical field of tower cranes, and particularly discloses a tower crane bottom fixing device which comprises a concrete base and a bottom frame fixedly connected with the concrete base. The concrete base is formed by pouring a reinforcing mesh and concrete; the reinforcing mesh is formed by fixing transverse reinforcing steel bars and longitudinal reinforcing steel bars, four tower crane embedded sections are arranged in gaps between the transverse reinforcing steel bars and the longitudinal reinforcing steel bars, the tops of the tower crane embedded sections are connecting parts, and the connecting parts vertically extend out of the concrete base; transverse bolt holes are formed in the side faces of the connecting parts, and the bottom frame is arranged on the outer sides of the connecting parts in a sleeving mode and connected with the connecting parts through bolts; a plurality of clamping plates are fixedly arranged on the tower crane embedded section, and transverse steel bars and longitudinal steel bars on the peripheral side of the tower crane embedded section are fixedly connected with the clamping plates correspondingly. The tower crane embedded section is poured in the concrete base, and the clamping plate is arranged on the tower crane embedded section, so that the reinforcing mesh and the reinforcing ribs are fixed on the clamping plate, and the stability of the tower crane is enhanced.
本发明属于塔吊技术领域,具体公开了一种塔吊底部固定装置,包括混凝土基座以及与混凝土基座固定连接的底部框架;混凝土基座为钢筋网和混凝土浇筑而成;钢筋网由横向钢筋和纵向钢筋固定而成,横向钢筋和纵向钢筋的空隙设置有四个塔吊预埋节,塔吊预埋节顶部为连接部,连接部垂直延伸至混凝土基座外部;连接部的侧面开设有横向的螺栓孔,底部框架套设在连接部外侧,且与连接部螺栓连接;塔吊预埋节上固定设置有若干卡板,塔吊预埋节周侧的横向钢筋和纵向钢筋分别与卡板固定连接。本发明通过将塔吊预埋节浇筑在混凝土基座内,并且通过在塔吊预埋节上设置卡板,使得钢筋网和加强筋固定在卡板上,增强了塔吊的稳定性。
