The gantry crane prefabricated foundation comprises a plurality of first foundations which are sequentially spliced end to end, and grooves are formed in the contact faces of the first foundations; the two sides of the connecting base and the side walls of the two adjacent first foundations are arranged at intervals, and the lower end of the connecting base is provided with a pair of sliding grooves and an elastic piece; the second foundation is clamped on the connecting seat, and the side wall of the lower end of the second foundation is clamped between the elastic piece and the first foundation; the pre-tensioning screw rod is vertically arranged on the first foundation and the connecting seat in a penetrating manner; and the steel rails are laid on the first foundation and the second foundation. After the connecting base is in stress connection with the first foundation, reverse elastic force is generated on the second foundation through the elastic piece composed of the compression spring and the wedge-shaped block, the second foundation abuts against the connecting base, the first foundation, the connecting base and the second foundation are spliced, and the beneficial effect that mounting and dismounting are convenient and fast is achieved.
本发明公开了一种龙门吊预制基础，包括：多个第一基础，首尾依次拼接，第一基础相接触的面上开设有凹槽；连接座，两侧分别与相邻两个第一基础的侧壁间隔设置，下端开设一对滑槽，且设有弹性件；第二基础，卡设于连接座上，其下端侧壁夹设于弹性件与第一基础之间；预拉螺杆，其竖向穿设于第一基础和连接座上；钢轨，其铺设于第一基础和第二基础上。本发明通过先将连接座与第一基础应力连接后，再通过由压缩弹簧和楔形块组成的弹性件对第二基础产生反向弹力，将第二基础抵接于连接座上，拼接第一基础、连接座和第二基础，具有安装拆卸便捷的有益效果。
