Example 4
Embodiment 4 differs from embodiment 3 in that the principle of embodiment 3 of converting tensile stress to the floor slab 25 into downward force to the transverse rods 33 is changed to utilize compressive stress to the floor slab 25 into downward force to the transverse rods 33, so that the fixing stirrups 61 are prevented from being excessively stressed and broken.

Secondly, since the arched square tube 67 can slide relative to the support rod 69, that is, the positions of the two ends of the arched square tube 67 are variable and the positions of the fixed ends of the third steel strand 62 are variable, when the cantilever beam 1 is overturned and the forces applied to the two transverse rods 33 are inconsistent, the forces are equal everywhere because the third steel strand 62 is pulled, and then the positions of the arched square tube 67 are adaptively slid according to the different forces required by the transverse rods 33 (see fig. 9), at this time, the winding angle and the positions of the third steel strand 62 relative to the transverse rods 33 are adaptively changed, and after the change, the winding angle and the positions of the third steel strand 62 relative to the two transverse rods 33 are still equal, so that the pressures applied to the two transverse rods 33 are equal and the directions are still perpendicular to the cantilever beam 1, so as to ensure that the forces of the two transverse rods 33 to the cantilever beam 1 are equal, so as to improve the effect of preventing the coverage of the fixed part 12 of the cantilever beam 1.
