[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figures 1 to 3 In an embodiment of the present invention, a tower crane support structure includes an upper mounting plate 1, and the four sides of the top of the upper mounting plate 1 are welded with an upwardly protruding No. 1 docking flange 2. The outer side of the No. 1 docking flange 2 is fixedly connected to the No. 2 docking flange 3 by bolts and nuts. The outer side of the No. 2 docking flange 3 is integrally welded with a support base 4. The support base 4 is an "L"-shaped structure, and a fixing flange 5 is welded to the bottom end of the support base 4; a reinforcement component is welded and installed on the support base 4, and the reinforcement component is used to improve the connection force between the crane standard section and the embedded component.

[0019] In this embodiment: first, the embedded component is fixed, and concrete is poured outside the embedded component. The lower half of the embedded component is buried in the concrete. After the concrete is completely dried and solidified, the reinforcement component is docked with the part of the embedded component located outside the concrete. After the docking is completed, the reinforcement component is installed and fixed. After that, the standard section at the bottom can be docked to complete the connection with the standard section of the tower crane.

[0020] Before docking the reinforcement component with the embedded component, first weld the No. 1 docking flange 2 on the top of the upper mounting plate 1. After the No. 1 docking flange 2 is fixed, the No. 2 docking flange 3 is welded to one end of the support base 4. Then, use bolts and nuts to connect the No. 1 docking flange 2 and the No. 2 docking flange 3. Finally, weld the fixing flange 5 to the bottom end of the support base 4 to complete the connection of the support base 4.

[0021] Please refer to Figure 1 、 Figure 2 and Figure 3 The reinforcement component includes a plurality of docking ears 6 welded to both sides of the support base 4, and docking plates 7 are welded on both sides of the support base 4 below the flange of the standard section. The docking plate 7 is located between two adjacent docking ears 6. The reinforcement component also includes an intermediate piece 10 welded to the bottom end of the upper mounting plate 1, and a lower mounting plate 11 is welded to the bottom end of the intermediate piece 10. Circular holes for docking with embedded components are opened on the upper mounting plate 1, the docking ears 6, the docking plates 7 and the lower mounting plate 11.

[0022] In this embodiment: when the reinforcement component is docked with the embedded component, the docking plate 7 is docked with multiple docking ears 6 and the embedded component one by one. The docking plate 7 and the docking ears 6 increase the connection points between the support base 4 and the embedded component, and the design of the docking plate 7 can assist in the auxiliary installation of the lowest standard section, thereby improving the auxiliary installation efficiency of the standard section.

[0023] Please refer to Figure 1 and Figure 2 The embedded component includes an embedded part 8 embedded in the concrete, the top of the embedded part 8 is welded with an embedded steel bar 9 aligned with the circular hole, and a nut is threadedly connected to the upper part of the outer wall of the embedded steel bar 9. The tightened nut is used to tighten the reinforcement component.

[0024] In this embodiment: when the support base 4 is lowered, the downwardly moving support base 4 drives the docking plate 7, the docking ear 6, the upper mounting plate 1 and the lower mounting plate 11 to dock with the embedded steel bars 9 one by one. Before the embedded steel bars 9 are fixed with the embedded parts 8, an external thread is turned on the upper end of the outer wall thereof using a turning tool. Then, the embedded parts 8 are welded to the bottom ends of the embedded steel bars 9. After welding, the embedded components are placed in a preset position and then fixed by pouring concrete.

[0025] After the embedded component and the reinforcement component are connected, use a nut to thread them together with the external thread and tighten the nut.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
