[0002] With the development of the construction industry, the research and application of scaffolding erection has developed rapidly, and various forms of scaffolding erection have emerged in large numbers. However, most of these scaffoldings are erected from the ground to high altitudes as a whole. The scaffolding project volume is large. For local construction areas with higher altitudes, the cost of erecting the scaffolding as a whole is high. Therefore, cantilever scaffolding for medium and high-rise buildings came into being.

[0003] When the existing cantilever frame is erected, when the anchoring position of the I-beam meets the shear wall of the next layer, a hole is generally opened in the shear wall to pass the I-beam through, and then the cantilever frame is anchored to the lower I-beam through the anchor ring for subsequent construction. The above construction method is time-consuming and labor-intensive to open a hole in the shear wall, and has factors such as slow construction speed, low efficiency, high cost, and increased construction quality risks. It will have a certain impact on the construction period, and will damage the internal steel bars of the wall, requiring subsequent large-area wall repair processes. Utility Model Content

[0026] like Figure 1-Figure 4 As shown, the utility model discloses a steel cantilever frame anchoring structure, comprising a shear wall 1, a concrete beam 2, an I-beam 3 arranged on the concrete beam 2, special-shaped anchor plates 4 arranged on both sides of the shear wall 1, a connecting rod 5 penetrating the shear wall 1 to fix the special-shaped anchor plates 4 to the shear wall 1, and a round steel 6 connecting the I-beam 3 and the special-shaped anchor plates 4. The I-beam 3 is a steel structure of the cantilever frame, which is used to fix the cantilever frame. The special-shaped anchor plates 4 include an upper steel plate 4.1, a lower steel plate 4.2, and a lower steel plate 4.3. The upper steel plate 4.2, the middle steel plate 4.3 connecting the upper steel plate 4.1 and the lower steel plate 4.2, and the side steel plates 4.4 connected to the upper steel plate 4.1, the lower steel plate 4.2 and the side of the middle steel plate 4.3. The upper steel plate 4.1 and the lower steel plate 4.2 are perpendicular to each other, and the middle steel plate 4.3 is inclined. When in use, the lower steel plate 4.2 is attached to the shear wall 1, and the connecting rod 5 passes through the shear wall 1 and the lower steel plate 4.2 and is fixed by double nuts.

[0027] Furthermore, two side steel plates 4.4 are arranged, which are arranged on the opposite sides of the upper steel plate 4.1, the lower steel plate 4.2 and the middle steel plate 4.3 respectively. By tilting the middle steel plate 4.3 and adding side steel plates 4.4, the rigidity of the special-shaped anchor plate 4 can be enhanced to avoid its deformation and fracture. Moreover, because the special-shaped anchor plate 4 may be deformed and fractured at the position where the upper steel plate 4.1 and the lower steel plate 4.2 are connected to the middle oblique steel plate under stress, the steel plates are fully welded on both sides of the special-shaped anchor plate 4 to form a whole. The stress point extends from the special-shaped anchor plate 4 to the steel plates on both sides, and the stress calculation is more reliable.

[0028] A wooden square 7 is provided between the upper steel plate 4.1 and the concrete beam 2, a wooden square 7 is provided between the I-beam 3 and the concrete beam 2, the upper end of the round steel 6 is locked with the I-beam 3 by a nut, a pad 8 is provided between the nut and the I-beam 3, and the lower end of the round steel 6 is locked with the upper steel plate 4.1 by a nut.

[0029] An elliptical hole 9 for passing the round steel 6 is opened on the upper steel plate 4.1, and a circular hole 10 for passing the connecting rod 5 is opened on the lower steel plate 4.2. By opening the elliptical hole 9, the position of the round steel 6 can be fine-tuned to avoid installation problems caused by installation errors. By opening the circular hole 10, the installation accuracy and stability of the special-shaped anchor plate 4 can be guaranteed.

[0030] The present application arranges an adaptive special-shaped anchor plate 4 on the shear wall 1, and the special-shaped anchor plate 4 and the shear wall 1 are fixed by a connecting rod 5. It is only necessary to drill holes in the shear wall 1, and there is no need to make holes in the shear wall 1. This simplifies the construction process, saves construction time, reduces construction costs, reduces quality risks, and improves construction efficiency.
