The inner wall of the main support framework is fixedly connected with a support rod. One side of the lower two fixed seats is fixedly connected with a reinforcement bracket. The end of the reinforcement bracket away from the fixed seat is fixedly connected with the reinforcement bracket. Four mounting seats are respectively arranged on the top surface of the building and the upper surface of the main support framework. A cantilever support is arranged on the mounting seat.

[0006] In some embodiments, the fixed seat is fixed to the side of the building by bolts, and the reinforcement bracket, the main support framework and the side of the building form a triangular framework.

[0007] In some embodiments, a reinforcement diagonal brace is fixedly connected to the inner walls of the two reinforcement brackets. The reinforcement diagonal brace is inclined and forms a triangular framework with the two reinforcement brackets.

[0008] In some embodiments, a reinforcement rod is arranged between the support rod and the main support framework. The reinforcement rod, the support rod and the main support framework form a triangular framework. A reinforcement connecting rod is arranged between the two main support frameworks. The reinforcement connecting rod penetrates through the reinforcement rod.

[0009] Compared with the prior art, the utility model has the following remarkable advantages:

[0010] The utility model rationally utilizes the limited space to install a tower crane, improves the use efficiency of the tower crane, the cantilever type combined foundation saves construction costs, has high installation efficiency, and is stable, safe and reliable in support.

[0011] It solves the problem that it is difficult to build the tower crane foundation at the construction site due to limited space or the lack of relatively stable support points around the building. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following details the present utility model, clearly and completely describes the technical solutions in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] The present utility model provides a tower crane foundation with a cantilever support structure through improvement. The technical solution of the present utility model is:

[0020] As Figure 1As shown in the figure, a tower crane foundation with a cantilever support structure includes a fixed seat 1 fixed to the side of a building. There are four fixed seats 1 in total. On one side of the two upper fixed seats 1, a main support framework 2 is fixedly connected. Inside the inner wall of the main support framework 2, a support rod 3 is fixedly connected. On one side of the two lower fixed seats 1, a reinforcement bracket 4 is fixedly connected. Both the main support framework 2 and the reinforcement bracket 4 are fixed to the fixed seat 1 by bolts, and the bolts used are in the form of climbing cones and can be reused. One end of the reinforcement bracket 4 far from the fixed seat 1 is fixedly connected to the reinforcement bracket 4. Four mounting seats 5 are respectively arranged on the top surface of the building and the upper surface of the main support framework 2. A cantilever support 6 is arranged on the mounting seat 5. The mounting seats 5 are separated in pairs. Two of them are on the building, and two of them are based on the main support framework 2 and are at the same horizontal position.

[0021] As Figure 2 shown, in an embodiment, the fixed seat 1 is fixed to the side of the building by bolts. The reinforcement bracket 4, the main support framework 2 and the side of the building form a triangular framework, and the triangular framework can further ensure the stability of the structure;

[0022] A reinforcement diagonal brace 7 is fixedly connected to the inner walls of the two reinforcement brackets 4. Both ends of the reinforcement diagonal brace 7 are welded and fixed to the inner walls of the two reinforcement brackets 4 respectively. The reinforcement diagonal brace 7 is inclined and forms a triangular framework with the two reinforcement brackets 4.

[0023] As Figure 3 shown, in an embodiment, a reinforcement rod 8 is arranged between the support rod 3 and the main support framework 2. There are two reinforcement rods 8. Both ends of the reinforcement rod 8 are fixed to the support rod 3 and the main support rod 3 bracket respectively by bolts. The reinforcement rod 8, the support rod 3 and the main support framework 2 form a triangular framework. A reinforcement connecting rod 9 is arranged between the two main support frameworks 2. The reinforcement connecting rod 9 penetrates through the reinforcement rod 8, and both ends of the reinforcement connecting rod 9 penetrate through the two reinforcement rods 8 at the same time, further enhancing the structural stability and compactness.

[0024] The specific working method is as follows: When the tower crane foundation with the cantilever support structure is in use, first set embedded bolts on the top surface and the side edge of the building foundation structure, install the fixed seat 1 and the mounting seat 5, then install the main support framework 2 and the reinforcement bracket 4, and weld the reinforcement bracket 4 to the support frame. Subsequently, install other reinforcement parts using bolts in sequence to form multiple triangular stable support structures to ensure the stability of the tower crane foundation. Finally, build the tower crane foundation support on the top in sequence.
