[0019] Embodiment: As Figures 1-3 shown, the present utility model provides a cantilever beam structure for a vertical wall, including a wall 1. A cantilever beam 2 is fixedly provided on one side of the wall 1. A steel beam 4 is jointly provided on one side of the wall 1 and the lower end of the cantilever beam 2. A plurality of fixing mechanisms 3 are provided on one side and the upper end of the steel beam 4. Two stirrups 20 are jointly provided inside the cantilever beam 2 and the wall 1. A plurality of inner frames 21 are fixedly provided on the outer surfaces of the two stirrups 20. Two primary straight bars 22 are jointly provided inside the cantilever beam 2 and the wall 1. One end of each of the two primary straight bars 22 is fixedly provided with a primary downward-bent bar 25. Two secondary straight bars 23 are jointly provided inside the cantilever beam 2 and the wall 1. One end of each of the two secondary straight bars 23 is fixedly provided with a secondary downward-bent bar 24. After the cantilever beam 2 is poured on one side of the wall 1, the stirrups 20 and the inner frames 21 provided inside the cantilever beam 2 and the wall 1 jointly form a stable force-bearing skeleton. Among them, the stirrups 20 enhance the overall stability of the structure. The primary straight bars 22 and the secondary straight bars 23 respectively achieve effective transmission and dispersion of force through the primary downward-bent bars 25 and the secondary downward-bent bars 24, improving the load-bearing capacity and anti-deformation ability of the cantilever beam. The setting of the inner frames 21 further strengthens the connection between the cantilever beam 2 and the wall 1, enhancing the overall rigidity and seismic performance of the structure.

[0020] Eight fixing mechanisms 3 are provided, and every four fixing mechanisms 3 are respectively arranged in a rectangular array on one side and the upper end of the steel beam 4. Eleven inner frames 21 are provided, and the eleven inner frames 21 are linearly arranged on the outer surfaces of the two stirrups 20. Two reinforcing bars 26 are fixedly provided on the inner surfaces of the plurality of inner frames 21. The fixing mechanisms 3 being arranged in a rectangular array can effectively improve the stability of the steel beam 4 on one side of the wall 1 and the lower end of the cantilever beam 2. The linear arrangement of the inner frames 21 enhances the overall rigidity and seismic performance of the structure. The reinforcing bars 36 on the inner frames 21 further improve the stability of the structure.

[0021] The fixing mechanism 3 includes a fixing cylinder 30. A plurality of anti-slip lines 34 are fixedly arranged on the outer surface of the fixing cylinder 30. A plurality of expansion grooves 35 are formed in the outer surface of the fixing cylinder 30. A screw rod 33 is arranged inside the fixing cylinder 30. A nut 32 is threadedly sleeved on the outer surface of the screw rod 33. One end of the screw rod 33 is fixedly provided with a fixing rod 37. One end of the fixing rod 37 is fixedly provided with a fixing block 36. Through the fixing mechanism 3, the fixing cylinder 30 is nailed into the reserved holes in the wall body 1 and the cantilever beam 2. Then, the nut 32 is rotated, so that the nut 32 can drive the screw rod 33 to move inside the fixing cylinder 30, thereby enabling the fixing cylinder 30 to drive the fixing block 36 to move through the fixing rod 37. When the fixing block 36 moves to one end of the fixing cylinder 30, the inner end of the fixing cylinder 30 can be internally supported through the expansion grooves 35, and the fixing cylinder 30 can be fixed in the reserved holes in cooperation with the anti-slip lines 34.

[0022] There are five anti-slip lines 34, and the five anti-slip lines 34 are evenly distributed on the outer surface of the fixing cylinder 30 at equal intervals. There are four expansion grooves 35, and the four expansion grooves 35 are annularly distributed on the outer surface of the fixing cylinder 30. A wear-resistant rubber ring 31 that is slidably sleeved on the outer surface of the screw rod 33 and is used in cooperation with the fixing cylinder 30 and the nut 32. The equal-spacing distribution of the anti-slip lines 34 can effectively increase the friction coefficient with the inner wall of the reserved hole. The annular distribution of the expansion grooves 35 can make the force more uniform. The nut 32 can prevent the fixing cylinder 30 from being worn through the wear-resistant rubber ring 31.

[0023] Working principle: After the cantilever beam 2 is poured on one side of the wall body 1, the stirrups 20 and the internal formwork 21 arranged inside the cantilever beam 2 and the wall body 1 together form a stable force-bearing skeleton. Among them, the stirrups 20 enhance the overall stability of the structure. The primary straight bars 22 and the secondary straight bars 23 respectively realize the effective transmission and dispersion of force through the primary downward-bent steel bars 25 and the secondary downward-bent steel bars 24, improving the load-bearing capacity and anti-deformation ability of the cantilever beam. The setting of the internal formwork 21 further strengthens the connection between the cantilever beam 2 and the wall body 1, enhancing the overall rigidity and seismic performance of the structure;

[0024] The fixing mechanisms 3 are respectively distributed in a rectangular array, which can effectively improve the stability of the steel beam 4 on one side of the wall body 1 and the lower end of the cantilever beam 2. The internal formwork 21 is linearly distributed, enhancing the overall rigidity and seismic performance of the structure. The reinforcing bars 36 on the internal formwork 21 further improve the stability of the structure;

[0025] Through the fixing mechanism 3, the fixing cylinder 30 is nailed into the reserved holes on the wall body 1 and the cantilever beam 2. Then, the nut 32 is turned, so that the nut 32 can drive the screw rod 33 to move in the fixing cylinder 30, thereby enabling the fixing cylinder 30 to drive the fixing block 36 to move through the fixing rod 37. When the fixing block 36 moves to one end of the fixing cylinder 30, the inner end of the fixing cylinder 30 can be supported through the expansion groove 35, and the fixing cylinder 30 can be fixed in the reserved hole in cooperation with the anti-slip pattern 34;

[0026] The anti-slip patterns 34 are evenly distributed at equal intervals, which can effectively increase the friction coefficient with the inner wall of the reserved hole. The expansion grooves 35 are annularly distributed, which can make the force more uniform. The nut 32 can prevent the fixing cylinder 30 from being worn through the wear-resistant rubber ring 31.

[0027] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model also intends to include these modifications and variations.
