During the pouring process of the lower floor 12, the first embedded component 31 is fixedly set on the lower floor 12 by pre-embedded means, and the compression component 32 is fixedly set on the first embedded component in the later stage Part 31, and the clamping component 32 is pressed against the inner section of the cantilever beam module 2 to lock the inner section of the cantilever beam module 2 to the lower floor 12; the tensioning module 4 includes a second embedded component 41 and a tensioning component 42. During the pouring process of the upper floor slab 11, the second embedded component 41 is fixedly arranged on the upper floor slab 11 by pre-embedded means, and one end of the tensioning component 42 is later arranged on the second embedded component 41, and the other end of the tensioning component 42 is also later arranged on the outer section of the cantilever beam module 2 to tighten the outer section of the cantilever beam module 2 through the upper floor slab 11; the scaffolding module 5 is a steel pipe scaffold in the prior art, and the scaffolding module 5 is detachably arranged on the outer section of the cantilever beam module 2 to achieve a protective effect on the exterior decoration during the construction process.

[0028] In this embodiment, the first embedded component 31 includes a horizontal section 311 and two groups of vertical sections 312. The horizontal section 311 and the two groups of vertical sections 312 are an integrally formed steel bar structure. The two groups of vertical sections 312 are respectively integrally formed and arranged at both ends of the horizontal section 311, that is, the horizontal section 311 and the two groups of vertical sections 312 together form a first embedded component 31 of a U-shaped structure. During the pouring process of the lower floor slab 12, the horizontal section 311 is embedded in the top wall of the lower floor slab 12, and the two groups of vertical sections 312 extend and expose the lower floor slab 12 (that is, the bottom of the horizontal section 311 and the two groups of vertical sections 312 are embedded in the lower floor slab 12), and the tops of the two groups of vertical sections 312 are both provided with external threads 313; the clamping component 32 specifically includes a clamping cover plate 321 and two groups of clamping nuts 322. The clamping cover plate 321 is The steel plate structure, the two sides of the compression cover 321 corresponding to the two groups of vertical sections 312 are provided with sliding holes, so that the two sides of the compression cover 321 can be slidably set on the two groups of vertical sections 312 respectively, and the two groups of compression nuts 322 are respectively threadedly connected to the two groups of external threads 313, and the two groups of compression nuts 322 are respectively tightened against the top of the two sides of the compression cover 321, so that the compression cover 321 is tightened against the inner section of the cantilever beam module 2. The specific operation process is to first place the inner section of the cantilever beam module 2 between the two groups of vertical sections 312, then slide the compression cover 321 through the two groups of vertical sections 312 and tighten it against the top of the inner section of the cantilever beam module 2, and finally, thread the two groups of compression nuts 322 into the two groups of external threads 313 and tighten them against the top of the compression cover 321, thereby pressing the inner section of the cantilever beam module 2 against the lower floor slab 12. Of course, the specific number of the compression modules 3 can be flexibly selected according to the on-site construction requirements.

[0029] In this embodiment, each set of clamping nuts 322 includes two nuts, which are pressed against each other; the two nuts are squeezed against each other, thereby improving the stability of the threaded connection between the clamping nut 322 and the external thread 313 through the friction force of the thread.

The lifting ring section 411 is a U-shaped structure, and the two groups of connecting sections 412 are L-shaped structures. The two groups of connecting sections 412 are integrally formed and arranged at both ends of the lifting ring section 411. During the pouring process of the upper floor slab 11, the two groups of connecting sections 412 are embedded in the outer wall of the upper floor slab 11, and the two groups of connecting sections 412 extend outward. The outer wall of the upper floor 11 is exposed, and the lifting ring section 411 integrally formed and arranged on the two sets of connecting sections 412 is also exposed on the outer wall of the upper floor 11 to form a closed ring structure. In addition, the two sets of connecting sections 412 are bent away from one end of the lifting ring section 411 to form a stabilizing hook 413 with a semicircular structure. The stabilizing hook 413 is pre-embedded with the connecting section 412 on the outer wall of the upper floor 11, thereby improving the connection stability between the second embedded component 41 and the upper floor 11; the tensioning component 42 specifically includes The steel bar pull ring 421, two sets of rigging rings 422 and steel wire rope 423 are respectively fixed to the outer section of the cantilever beam module 2 by welding to form a closed ring structure, and can be retained during the later disassembly process of the cantilever beam module 2 without cutting and disassembling. The two sets of rigging rings 422 are respectively movably set on the steel bar pull ring 421 and the lifting ring section 411. The two ends of the steel wire rope 423 are respectively fixed to the two sets of rigging rings 422 by four sets of preset rope clips 424. The connection method between the ring 422, the wire rope 423 and the rope clamp 424 is a common technical means in the construction process. The feature of this embodiment is that between the two sets of rope clamps 424 away from the steel bar pull ring 421 / hanging ring section 411, the wire rope 423 is bent into an arc shape to form a safety bend 425. In addition, the end of the wire rope 423 is fixed to the interruption position of the wire rope 423 itself by welding. Both settings are mainly aimed at improving the connection stability of the tensioning assembly 42.

[0031] In this embodiment, a cross beam 7 is fixedly provided on the top of the outer section of the cantilever beam module 2, and the cantilever beam module 2 is arranged perpendicular to the cross beam 7, that is, multiple groups of outer sections of the cantilever beam modules 2 support multiple groups of cross beams 7, and vertically arranged positioning columns 6 are fixed on the top of the cross beam 7 by welding. The positioning columns 6 are plugged and adapted to the bottom of the scaffolding module 5, so that the positioning columns 6 are plugged into the bottom of the scaffolding module 5, which is used to limit the horizontal freedom of movement of the bottom of the scaffolding module 5, thereby improving the installation stability and safety of the scaffolding module 5.

[0032] In this embodiment, the cantilever beam module 2 is an I-beam structure, and the crossbeam 7 is an I-beam structure. Specifically, the cantilever beam module 2 is a No. 16 I-beam, and the crossbeam 7 is a No. 16 I-beam. The I-beam's excellent resistance to deformation and bending deformation ensures that the cantilever support structure has sufficient stability.

[0033] In this embodiment, the ratio of the length of the inner section of the cantilever beam module 2 to the outer section of the cantilever beam module 2 is 4.5:3.3. Specifically, the inner section of the cantilever beam module 2 is 4500 mm long, and the distance between the compression module 3 and the end of the inner section of the cantilever beam module 2 is 200 mm. The outer section of the cantilever beam module 2 is 3300 mm long, and the distance between the tension module 4 and the end of the outer section of the cantilever beam module 2 is 100 mm. Of course, in other embodiments, the ratio of the inner section of the cantilever beam module 2 to the outer section of the cantilever beam module 2 can be set to other ratios.

[0034] Implementation principle: During the pouring process of the lower floor slab 12, the first embedded component 31 is fixedly set on the top wall of the lower floor slab 12 by pre-embedded method. During the pouring process of the upper floor slab 11, the second embedded component 41 is fixedly set on the outer wall of the upper floor slab 11 by pre-embedded method. During the installation process of the inner section of the cantilever beam module 2, the inner section of the cantilever beam module 2 is first placed between the two groups of vertical sections 312 of the first embedded component 31, and then the pressing cover plate 321 is slid between the two groups of vertical sections 312 and pressed against the top of the inner section of the cantilever beam module 2. Finally, the two sets of compression nuts 322 are respectively threadedly connected to the two sets of external threads 313 and pressed against the top of the compression cover plate 321, thereby pressing the inner section of the cantilever beam module 2 to the lower floor slab 12; during the installation process of the outer section of the cantilever beam module 2, the two sets of rigging rings 422 are respectively movably set on the steel bar pull ring 421 and the lifting ring section 411, and the two ends of the wire rope 423 are respectively fixed to the two sets of rigging rings 422 through four sets of rope clips 424, thereby tightening the outer section of the cantilever beam module 2 through the upper floor slab 11.

[0035] After the construction is completed, the compression component 32 and the tensioning component 42 can be dismantled without loss of quality, the first embedded component 31 and the second embedded component 41 can be retained or removed, and the steel bar pull ring 421 can be retained in the cantilever beam module 2, thereby achieving the cantilever beam module 2 without loss of quality, saving manpower and material resources, and avoiding cutting and wear on the cantilever beam module 2 as much as possible, which is conducive to the long-term reuse of the cantilever beam module 2.

[0036] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be covered within the scope of protection of the present application.
