[0002] A cantilever structure is a suspended structure that extends outward from a building, usually set on the outer edge of the building's roof; the cantilever structure construction of a low-rise building usually involves building a ground-based formwork frame from the ground to support the steel skeleton, and then pouring concrete on the steel skeleton to form a cantilever structure. However, the roof cantilever structure of a high-rise building has problems such as large suspended height, large span, and heavy weight. If it is built with a ground-based formwork frame, the number of components used in the formwork frame is huge, and there are problems such as high cost, difficulty, and low efficiency, which need to be improved.

[0006] The diagonal bracing steel is fixed with a first connecting piece, and the vertical steel and the diagonal steel are commonly connected to the first connecting piece; one end of the vertical steel away from the diagonal bracing steel is vertically fixed to the supporting steel through the second connecting piece, and one end of the diagonal steel away from the diagonal bracing steel is fixedly connected to the connection position between the supporting steel and the building structure through the third connecting piece.

[0007] By adopting the above technical solution, when constructing the cantilever structure of a high-rise building, by setting embedded parts on the outer side of the building structure to fix the supporting steel and the diagonal steel, the end of the diagonal bracing steel is connected to the end of the supporting steel, and a triangular support structure with good stability can be formed between the supporting steel, the diagonal bracing steel and the building wall; in addition, by adding vertical steel and diagonal steel between the supporting steel and the diagonal bracing steel, a stable triangular support structure can be further formed, so that the entire support frame has good structural strength. After the support frame is built, it can be used as a platform for the formwork frame to be supported and fixed, without the need to build it from the ground up, which can greatly reduce the use of components of the formwork frame, reduce construction costs and difficulty, and thus improve the construction efficiency of high-altitude cantilever structures.

[0008] Optionally, the support frame also includes a protective pole arranged at an end of the supporting steel away from the building structure, the protective pole is vertically arranged, and all the protective poles are commonly connected to a first steel wire rope.

[0037] Reference Figure 2 The support frame 1 includes a supporting steel 11, a vertical steel 12, a diagonal bracing steel 13, a diagonal steel 14 and a protective upright 15; a first embedded part 91 and a second embedded part 92 are arranged inside the wall of the building structure 9, the first embedded part 91 is located above the second embedded part 92, the first embedded part 91 is used to fix the third connecting part 7, and one end of the supporting steel 11 is fixedly connected to the third connecting part 7 by a fastener, thereby realizing the fixation between the supporting steel 11 and the building structure 9; the other end of the supporting steel 11 extends outward, and the whole is arranged horizontally.

[0038] The second embedded part 92 is used to fix the fourth connecting member 8, and one end of the diagonal bracing steel 13 is fixedly connected to the fourth connecting member 8 by a fastener, thereby achieving fixation between the diagonal bracing steel 13 and the building structure 9; one end of the diagonal bracing steel 13 away from the building structure 9 is fixedly connected to the bottom of the supporting steel 11, and the diagonal bracing steel 13 and the supporting steel 11 are arranged at an angle, which is used to form a triangular supporting structure between the supporting steel 11, the supporting steel and the wall of the building structure 9, thereby improving the supporting stability of the support frame 1 and the entire erection platform.

[0039] The angle in this embodiment is 45°. It can be understood that in other feasible implementations, the angle between the diagonal bracing steel 13 and the supporting steel 11 can also be 40° or 50°, which needs to be obtained based on the force analysis of actual conditions and is not limited to the angle adopted in this embodiment.

[0040] The middle section of the diagonal bracing steel 13 is fixed with a first connecting member 5, and the first connecting member 5 is located on the top surface of the diagonal bracing steel 13. The vertical steel 12 and the diagonal steel 14 are connected to the first connecting member 5. The end of the vertical steel 12 away from the diagonal bracing steel 13 is fixedly connected to the supporting steel 11 through the second connecting member 6, and the vertical steel 12 is vertically arranged to mainly support the vertical load. The end of the diagonal steel 14 away from the diagonal bracing steel 13 is fixedly connected to the third connecting member 7, that is, fixedly connected to the connection position of the supporting steel 11 and the building structure 9, and can also form a triangular support structure to further improve the support stability of the support frame 1.

[0041] There are multiple connecting beams 2, each connecting beam 2 is connected between two adjacent first connecting members 5 of adjacent brackets 1, and the connecting beam 2 and the first connecting member 5 are fixed by fasteners.

[0042] A supporting steel 16 is fixed to the top of all the supporting steels 11. The supporting steel 16 is arranged horizontally, and the extension direction of the supporting steel 16 is perpendicular to the extension direction of the supporting steel 11. In addition, there are multiple supporting steels 16, and all the supporting steels 16 are arranged at intervals along the extension direction of the supporting steel 11.

At the same time, the first steel wire rope 3 can also be hooked and firmly hooked by the safety rope hook of the construction personnel to ensure personal safety. It can be understood that in order for the first hook buckle 31 to pass through the hook 151 smoothly, the size of the first hook buckle 31 needs to be smaller than the inner diameter of the hook 151.

[0045] The implementation principle of Example 1 of the present application is:

[0046] When constructing a cantilever structure of a high-rise building, a triangular support structure is formed between the supporting steel 11, the diagonal bracing steel 13 and the building wall, which has good stability; and by adding vertical steel 12 and diagonal steel 14 between the supporting steel 11 and the diagonal bracing steel 13, a stable triangular support structure can be further formed, so that the entire support frame 1 has good structural strength. After the support frame 1 is built, it can be used as a platform for the formwork frame to be supported and fixed, without the need to build it from the ground up, which can greatly reduce the use of the components of the formwork frame, reduce construction costs and difficulty, and thus improve the construction efficiency of the high-altitude cantilever structure.
