In the embodiment of the present application, see Figure 4 As shown, according to the design positioning, a hole is opened in advance in the N-th floor slab and a Φ20 U-shaped anchor ring 211 is punched upward from the bottom of the slab. When the concrete of the N+1-th floor structural side beam is poured, a Φ20 round steel 221 is pre-embedded in advance to anchor the inclined steel wire rope 222.

[0034] Please refer to Figure 4 After the processing of the protective platform 10 is completed, it is transported to the construction site and hoisted to the Nth floor by a tower crane. The construction workers wear safety protective equipment, stand on the side of the structure and coordinate with the tower crane to move the anchor end of the main beam 111 to the floor slab, and temporarily stabilize it in the designed position, with the cantilevered protective end close to the side of the structure. The construction workers first install the anchor ring anchor of the Nth floor slab. The Φ20 U-shaped anchor ring 211 is perforated from the bottom of the slab and fastened and connected to the main beam 111 with two high-strength bolts. An 8mm thick steel pad is set at the high-strength bolt fastening location, and the exposed bolt section is not less than 100mm. The gap between the I-beam main beam and the U-shaped anchor ring 211 is laterally plugged with a wooden wedge to ensure the stability of the anchor ring anchor of the floor slab. Each main beam 111 is provided with three U-shaped anchor rings 211 within the anchoring length, one of which is provided near the structural edge line, 250mm away from the structural edge line, and two of which are provided at the end of the anchoring length of the main beam 111, 200mm and 400mm away from the end respectively. After the anchoring installation of the floor anchor ring of the cantilever protection platform 10 is completed, the protection platform has been basically installed and stabilized. The construction personnel will embed the round steel 221 at the structural edge beam at the N+1 layer position corresponding to the cantilever protection platform to connect the steel wire 222.

The second shackle 225 is hung on the diagonal lifting lug 50 on the main beam, and the steel wire 222 is used to tie and anchor the N+1 layer structure embedded round steel 221. When the angle between the protection platform 10 and the structural plate surface is adjusted to 2-3°, the basket bolt 224 is adjusted to tighten the steel wire 222 to ensure that the force distribution of the anchor ring anchor 21 and the diagonal anchor 22 is uniform and reasonable.

Figure 1-3 Specifically, four anti-bending reinforcement members 114 are arranged at the nodes of the two transverse secondary beams 112 and the main beam 111 on both sides of the length direction of the protection platform 10 to prevent the protection platform 10 from bending and deforming due to the deadweight of the outer side of the main beam 111. The anti-bending reinforcement member 114 includes a square tube 1141, a pressure plate 1142, and a U-shaped clamp 1143. The square tube 1141 has a cross-sectional size of 50mm×50mm×5mm and a length of 1.5m. The pressure plate 1142 has a size of 40mm×63mm×4mm. The U-shaped clamp 1143 is Φ16 round steel.
