[0042] Specifically, after the U-shaped metal pull ring 23 is connected to one end of the steel cantilever beam 21, the steel pressing plate 25 and the nut 26 are used together to press down and fix one end of the steel cantilever beam 21, so as to quickly build the support assembly 2;

[0043] The positioning plate 31 and the linkage plate 32 are first assembled on the steel cantilever beam 21 before the steel cantilever beam 21 is installed, so that the two ends of the positioning plate 31 are fixed to the inner wall of the steel cantilever beam 21, and the I-shaped groove 310 on the linkage plate 32 is sleeved on the outside of the steel cantilever beam 21, so that the inclined-stayed assembly is in the positioning stage before assembly;

[0044] After the first self-locking bolt 39 is loosened, it is separated from the first inclined rod 36, which is convenient for fixing one end of the second inclined rod 38 to a side wall of the third structural beam 5. After the second self-locking bolt 314 is loosened, it is separated from the third inclined rod 311, which is convenient for fixing one end of the fourth inclined rod 313 to the mounting rod 315. When the operator rotates the hexagonal block 34, the threaded linkage plate 32 and the internal threaded tube 35 connected thereto are moved in the opposite direction during the rotation of the screw rod 33, so as to simultaneously push the position of the first inclined rod 36 in the first sleeve 37 and the position of the third inclined rod 311 in the second sleeve 312, and in the process of tightening and rotating the first self-locking bolt 39 and the second self-locking bolt 314, the first inclined rod 36 and the third inclined rod 311 are fixed at an angle.

[0045] The top of the positioning shaft 27 drives the self-locking block 61 during the rotation process, so that when the self-locking block 61 rotates to one side, the two groups of first self-locking blocks 65 in the first self-locking cavity 63 are firstly used to tighten and position the connection gap between the first sweeping rod 7 and the first self-locking cavity 63, and the rotation direction of the self-locking block 61 can push the first sweeping rod 7 toward the position of the central axis of the self-locking block 61 to prevent the first sweeping rod 7 from falling off and displacement, and then the two groups of second self-locking blocks 66 in the second self-locking cavity 64 are used to tighten and position the connection gap between the second sweeping rod 8 and the second self-locking cavity 64, and the rotation direction of the self-locking block 61 can push the second sweeping rod 8 toward the position of the central axis of the self-locking block 61 to prevent the second sweeping rod 8 from falling off and displacement.

[0046] The working principle of the inclined-pull reaction-force cantilever scaffolding proposed by the embodiment of the present invention is as follows:

[0047] After the U-shaped metal pull ring 23 is connected to one end of the steel cantilever beam 21, the steel pressing plate 25 and the nut 26 are used together to press down and fix one end of the steel cantilever beam 21, so as to quickly build the support assembly 2;

[0048] The positioning plate 31 and the linkage plate 32 are first assembled on the steel cantilever beam 21 before the steel cantilever beam 21 is installed, so that the two ends of the positioning plate 31 are fixed on the inner wall of the steel cantilever beam 21, and the I-shaped groove 310 on the linkage plate 32 is sleeved on the outside of the steel cantilever beam 21, so that the inclined-stayed assembly is in the positioning stage before assembly;

[0049] After the first self-locking bolt 39 is loosened, it is separated from the first inclined rod 36, so that one end of the second inclined rod 38 is fixed to a side wall of the third structural beam 5, and after the second self-locking bolt 314 is loosened, it is separated from the third inclined rod 311, so that one end of the fourth inclined rod 313 is fixed to the mounting rod 315. When the operator rotates the hexagonal block 34, the threaded linkage plate 32 and the internal threaded tube 35 connected thereto are moved in the opposite direction during the rotation of the screw rod 33, so as to simultaneously push the position of the first inclined rod 36 in the first sleeve 37 and the position of the third inclined rod 311 in the second sleeve 312, and in the process of tightening and rotating the first self-locking bolt 39 and the second self-locking bolt 314, the first inclined rod 36 and the third inclined rod 311 are fixed in angle.

[0050] By driving the self-locking block 61 through the top of the positioning shaft 27 during rotation, the self-locking block 61 is rotated to one side. First, the two groups of first self-locking blocks 65 in the first self-locking cavity 63 are tightly fixed at the connection gap between the first sweeping rod 7 and the first self-locking cavity 63, and the rotation direction of the self-locking block 61 can push the first sweeping rod 7 toward the position of the central axis of the self-locking block 61 to prevent the first sweeping rod 7 from falling off and displacement. Then, the two groups of second self-locking blocks 66 in the second self-locking cavity 64 are tightly fixed at the connection gap between the second sweeping rod 8 and the second self-locking cavity 64, and the rotation direction of the self-locking block 61 can push the second sweeping rod 8 toward the position of the central axis of the self-locking block 61 to prevent the second sweeping rod 8 from falling off and displacement.

[0051] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
