Technical Field
[0001] This invention specifically relates to a basket-style pull-up cantilevered external scaffold and its construction method, and pertains to the field of building construction technology. Background Technology
[0002] Cantilevered scaffolding is an indispensable temporary support structure in construction operations. Among them, basket-stayed cantilevered scaffolding is widely used due to its advantages such as large cantilever distance and space saving. In existing technology, this type of scaffolding mainly relies on pre-embedded parts installed at the cantilever end of the I-beam and the top of the upper tie rod, which are then anchored inside the concrete wall to form a stable triangular force relationship. However, this system has structural safety risks: for example, when the pre-embedded parts at the connection between the I-beam and the wall break or fall off due to excessive stress or construction defects, the side of the I-beam closer to the wall lacks effective restraint and is prone to tilting downwards, disrupting the original triangular equilibrium state. This leads to a sudden change in the force state of the entire scaffolding system, significantly reducing stability and seriously threatening construction safety. At the same time, the traditional pre-embedded part structure is too simplified, often using a single screw rod with a simple sleeve embedded in the concrete. Its bond strength with the concrete is insufficient, and it is prone to loosening and outward slippage under long-term alternating loads, further weakening the anchoring reliability. In addition, existing construction methods rely on a large amount of on-site welding and bolting, and the installation process is cumbersome and requires high precision, resulting in low scaffolding erection efficiency. During the dismantling stage, the removal of welded points not only increases labor and time costs, but also easily damages the main structure. Therefore, it is necessary for our company to provide a basket-pull-up cantilever external scaffolding and its construction method to improve the existing technology. Summary of the Invention
[0003] To address the shortcomings of existing technologies, the present invention aims to provide a basket-link pull-up type cantilever external scaffold and its construction method that improves the failure resistance of embedded structures, optimizes the reliability of node connections, and simplifies the construction process, thereby solving the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a cantilevered external scaffold with a basket-like tie rod, comprising a template frame, transverse reinforcing bars and U-shaped reinforcing bars located inside the template frame, and I-beams locked to the outside of the template frame. An inner sliding frame and an outer sliding frame are fitted onto the I-beams. An upper vertical basket-like tie rod and a lower vertical basket-like tie rod are hinged to the upper and lower sides of the inner sliding frame, respectively. An upper inclined basket-like tie rod and a lower inclined basket-like tie rod are hinged to the upper and lower sides of the outer sliding frame, respectively. The ends of the upper vertical basket-like tie rod and the upper inclined basket-like tie rod are movably connected to double-tube embedded parts, forming an upper triangular support structure. The ends of the lower vertical basket-like tie rod and the lower inclined basket-like tie rod are also connected to double-tube embedded parts. Furthermore, a lower triangular support structure is formed between them, which stabilizes and supports the I-beam through the upper and lower triangular support structures; the double-tube embedded part is embedded through and inside the template frame, and the double-tube embedded part is located on one side of the transverse reinforcement and U-shaped reinforcement, and will be integrated with the transverse reinforcement and U-shaped reinforcement after the concrete is formed; a single-tube embedded part is locked on one side of the I-beam, and the single-tube embedded part is also embedded through and inside the template frame, and is located on one side of the transverse reinforcement and U-shaped reinforcement.
[0005] Based on the above technical solution, the double-pipe embedded part includes two parallel outer pipe sleeves, and a connecting plate is provided on one side of the two outer pipe sleeves to form an integral U shape. The two outer pipe sleeves are inserted by the upper and lower sides of the horizontal reinforcing bars at the same level.
[0006] Based on the above technical solution, the outer sleeve has multiple openings on one side, and a rotating rod is rotatably embedded inside each opening. An inner elastic ring is embedded and fixed inside the outer sleeve. Multiple round beads distributed in a ring are wrapped and fixed in the middle of the inner elastic ring. Each rotating rod, inner elastic ring and round bead is locked together by screws. The rotating rod is tightened in the opening under the elastic action of the inner elastic ring. The inner side of each outer sleeve is spirally connected with a high-strength bolt rod. When the high-strength bolt rod is fully tightened inside the outer sleeve, it pushes the ball to move outward and pushes each rotating rod to rotate and protrude outward to form an anchoring structure. At the same time, it corresponds to the side of the transverse steel bar and is integrated with the concrete.
[0007] Based on the above technical solution, the inner elastic ring is made of elastic rubber and locked inside the outer sleeve. The outer ends of the two high-strength bolts of the upper double-tube pre-embedded part are rotatably connected to the upper vertical turnbuckle and the upper inclined turnbuckle, respectively. The outer ends of the two high-strength bolts of the lower double-tube pre-embedded part are rotatably connected to the lower vertical turnbuckle and the lower inclined turnbuckle, respectively.
[0008] Based on the above technical solution, the structure of the single-pipe embedded part is consistent with the structure of the single outer pipe sleeve. The outer end of the high-strength bolt rod of the single outer pipe sleeve is locked with a first side mounting plate, and the first side mounting plate is locked to the I-beam.
[0009] Based on the above technical solution, the upper and lower sides of the I-beam are provided with multiple mounting holes. The inner and outer sliding frames are locked to the mounting holes by bolts. A second mounting plate is integrally provided on one side of the I-beam, and the second mounting plate is locked to the first mounting plate by multiple bolts.
[0010] Based on the above technical solution, multiple concave sliders are slidably arranged on the convex edges of the upper and lower sides of the I-beam. A crossbeam plate is arranged on the outside of the concave slider. The two ends of the crossbeam plate are respectively placed between the concave sliders on the upper side of the two I-beams. The crossbeam plate, the concave sliders and the mounting holes are locked and fixed by bolts. The locked concave sliders strengthen the limiting of the inner and outer sliding frames.
[0011] Based on the above technical solution, a groove is provided in the middle of the I-beam, and an external sliding bracket is provided in the groove. The external sliding bracket is supported by the foundation. The external sliding bracket includes a sliding plate that is slidably embedded in the inner side of the groove. Both the I-beam and the sliding plate have pin holes in the middle for fixing the sliding plate. A spiral tube is vertically fixed at the outer end of the sliding plate. A vertical screw rod is threaded through the middle of the spiral tube. An upper tightening nut and a lower tightening nut are respectively threaded on the vertical screw rod above and below the spiral tube. Rubber pads for tightening the upper and lower sides of the spiral tube are provided on opposite sides of the upper and lower tightening nuts. The bottom end of the vertical screw rod is supported by the foundation surface. The upper and lower ends of the vertical screw rod are respectively provided with mutually compatible inserts and slots, so that multiple vertical screw rods can be interlocked and spliced into a whole.
[0012] Based on the above technical solution, the upper sides of the crossbeams on both sides of the I-beam are fixed to the scaffolding with bolts for primary fixation. A reinforcing screw is installed through the middle of the crossbeam on the lower side of the I-beam, and the reinforcing screw is threaded to the bottom of the scaffolding for secondary fixation after passing through the two opposite crossbeams. The scaffolding includes multiple vertically arranged uprights and hollow buckles on the upper and lower sides of the uprights. Side bars are hung between the hollow buckles to form a rectangular frame. The bottom of the uprights is integrally provided with a lower screw tube, which is threaded to the top of the reinforcing screw.
[0013] A construction method for a basket-link cantilevered external scaffolding involves first laying the formwork frame, horizontal reinforcing bars, and U-shaped reinforcing bars. Then, holes are drilled in the formwork frame using a drilling machine to insert and install double-pipe and single-pipe embedded parts. The single-pipe and two double-pipe embedded parts are inserted into their corresponding holes, with both positioned on one side of the horizontal and U-shaped reinforcing bars. Concrete is then poured into the formwork frame and allowed to solidify. I-beams are then installed on the single-pipe embedded parts. Finally, inner and outer sliding frames are fitted onto the I-beams and bolted in place. The inner sliding frame has its upper and lower sides respectively... The upper and lower vertical turnbuckles are hinged together, while the upper and lower inclined turnbuckles are hinged together on the upper and lower sides of the outer sliding frame. The top ends of the upper vertical and inclined turnbuckles are then rotatably connected to the upper double-pipe embedded parts to form an upper triangular support structure. The ends of the lower vertical and inclined turnbuckles are rotatably connected to the lower double-pipe embedded parts to form a lower triangular support structure. The I-beam is stabilized, tightened, and supported by the support of the double-pipe and single-pipe embedded parts combined with the upper and lower triangular support structures.
[0014] By adopting the above technical solution, the present invention has the following advantages: 1. This invention uses an upper triangular support structure formed by an inner sliding frame, an upper vertical turnbuckle, an outer sliding frame, an upper inclined turnbuckle, and an upper double-tube embedded part to stably tension the I-beam. This structure, combined with a lower triangular support structure formed by an inner sliding frame, a lower vertical turnbuckle, an outer sliding frame, a lower inclined turnbuckle, and a lower double-tube embedded part, provides stable support to the I-beam. Even if the inner side of the I-beam breaks or detaches from the single-tube embedded part, the upper and lower triangular support structures can still stably tension and support the I-beam, ensuring effective horizontal support. 2. Furthermore, the double-tube embedded parts can be distributed and secured by the horizontal reinforcing bars on both the top and bottom sides. This allows the horizontal reinforcing bars to provide better support for the double-tube embedded parts. After the concrete sets, it also improves the support strength and connection effect of the double-tube embedded parts in the wall. It is also less likely to cause vertical displacement and wall loosening when tensioned or under support stress. Combined with the triangular structure of the lower support and the upper tension, it can effectively improve the stability of the cantilevered steel frame and greatly provide safety assurance for construction. 3. Simultaneously, both the double-tube and single-tube embedded parts have a rotating rod on one side of the outer sleeve that can be pushed outward by the high-strength bolt rod. After the rotating rod is unfolded, it forms an anchoring structure to solidify with the concrete, making it less likely for the outer sleeve of the double-tube and single-tube embedded parts to fall off or shift outward. The transverse steel bars on one side of the rotating rod can further hold the rotating rod in place to prevent it from detaching outward. The inner elastic ring plate installed inside the outer sleeve can not only elastically tighten the rotating rod, but also adapt to the pushing of the ball by the high-strength bolt rod. It can also act as a seal to prevent external concrete from entering the double-tube embedded part through the opening, thus reducing the impact of concrete on the use of the high-strength bolt rod in the later stages. 4. Furthermore, when building scaffolding on the bottom layer of I-beams, the I-beams are equipped with horizontal beams spaced apart vertically, and each horizontal beam rests between two I-beams. This design facilitates the replacement of the horizontal beams individually later. Moreover, after the bottom of the scaffolding is bolted to the upper horizontal beam, a reinforcing bolt can be used to pass through the upper horizontal beam from the lower horizontal beam and spiral into the lower threaded pipe at the bottom of the scaffolding for secondary locking, thereby improving the stability of the entire lower threaded pipe. 5. In addition, an external sliding bracket is slidably installed on the outside of each I-beam. When installing lower-level I-beams, the vertical screw of the external sliding bracket can be adjusted to contact the ground surface for auxiliary support. The auxiliary support of the vertical screw can further prevent the I-beam from tilting and keep it in a horizontal support state. Moreover, the upper and lower ends of the vertical screw are respectively equipped with mutually compatible inserts and slots. This allows multiple vertical screws to be interlocked and spliced into a whole, so that I-beams of different layers can be supported synchronously to improve the support effect.

Detailed Implementation
[0016] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0017] like Figure 1-9 As shown in the figure, this invention provides a technical solution for a cantilevered external scaffold with a basket-like tie rod, comprising a template frame 1, transverse reinforcing bars 101 and U-shaped reinforcing bars 102 located inside the template frame 1, and an I-beam 2 locked to the outside of the template frame 1. An inner sliding frame 30 and an outer sliding frame 31 are fitted onto the I-beam 2. An upper vertical basket-like tie rod 301 and a lower vertical basket-like tie rod 302 are hinged to the upper and lower sides of the inner sliding frame 30, respectively. An upper inclined basket-like tie rod 311 and a lower inclined basket-like tie rod 312 are hinged to the upper and lower sides of the outer sliding frame 31, respectively. Double-tube embedded parts 4 are movably connected to the ends of the upper vertical basket-like tie rod 301 and the upper inclined basket-like tie rod 311, forming an upper triangular support structure. Similarly, double-tube embedded parts 4 are connected to the ends of the lower vertical basket-like tie rod 302 and the lower inclined basket-like tie rod 312. Furthermore, a lower triangular support structure is formed between them. The upper and lower triangular support structures stabilize and support the I-beam 2. In this way, even if the inner side of the I-beam 2 breaks or detaches from the single-pipe embedded part 5, the upper and lower triangular support structures can still stabilize and support the I-beam 2, ensuring the horizontal support effect and stability of the I-beam 2.
[0018] The double-tube embedded part 4 is embedded inside the formwork frame 1, and is located on one side of the transverse reinforcement 101 and U-shaped reinforcement 102. After the concrete is formed, it will solidify with the transverse reinforcement 101 and U-shaped reinforcement 102. A single-tube embedded part 5 is locked on one side of the I-beam 2. This single-tube embedded part 5 is also embedded inside the formwork frame 1, and is located on one side of the transverse reinforcement 101 and U-shaped reinforcement 102. The double-tube embedded part 4 and the single-tube embedded part 5 simultaneously support the I-beam 2. The double-tube embedded part 4 includes two parallel outer sleeves 41. A connecting plate 412 is provided on one side of the sleeve 41, so that the two outer sleeves 41 form an integral U shape. The two outer sleeves 41 are inserted by the horizontal steel bars 101 at the same level from the top and bottom. This allows the horizontal steel bars 101 to provide better support for the double-pipe embedded parts 4. After the concrete sets, it also improves the support strength and connection effect of the double-pipe embedded parts 4 in the wall. It is also less likely to cause vertical displacement and wall loosening when tightened or under support stress. Combined with the triangular structure of lower support and upper tension, it can effectively improve the stability of the cantilever steel frame and greatly provide safety guarantee for construction.
[0019] Furthermore, the outer sleeve 41 has four openings 43 on one side, and a rotating rod 44 is rotatably embedded inside each opening 43. An inner elastic ring plate 45 is embedded and fixed inside the outer sleeve 41. The inner elastic ring plate 45 has four ring-shaped beads 46 wrapped and fixed in the middle. The four rotating rods 44 are locked to each inner elastic ring plate 45 and bead 46 by screws, so that the rotating rods 44 are tightened in the opening 43 under the elastic action of the inner elastic ring plate 45. In this way, the outer sleeve 41 is not easily obstructed after being inserted into the template frame 1. Furthermore, the inner side of the outer sleeve 41 is spirally connected with a high-strength bolt rod 42. When the high-strength bolt rod 42 is fully tightened inside the outer sleeve 41, it pushes the four beads 46 to move outward. The four beads 46 push each rotating rod 44 to rotate and protrude outward from the opening 43 to form an anchoring structure, which is simultaneously integrated with the concrete on the side of the transverse steel bar 101.
[0020] In the above technical solution, the inner elastic ring 45 is made of elastic rubber and is locked inside the outer sleeve 41 to seal the opening 43. The outer ends of the two high-strength bolt rods 42 of the upper double-pipe embedded part 4 are rotatably connected to the upper vertical turnbuckle 301 and the upper inclined turnbuckle 311, respectively. The outer ends of the two high-strength bolt rods 42 of the lower double-pipe embedded part 4 are rotatably connected to the lower vertical turnbuckle 302 and the lower inclined turnbuckle 312, respectively. In this way, the upper vertical turnbuckle 301 and the upper inclined turnbuckle 311, as well as the lower vertical turnbuckle 302 and the lower inclined turnbuckle 312, can all rotate adaptively, so that the inner sliding frame 30 and the outer sliding frame 31 can slide to different positions for tensioning and support. It is simple and flexible to use and has good adaptability.
[0021] Among them, the structure of the single pipe embedded part 5 is consistent with the structure of the single outer pipe sleeve 41. The high-strength bolt rod 42 of the single outer pipe sleeve 41 is locked at the outer end of the first side mounting plate 51, and the first side mounting plate 51 is locked to the I-beam 2. Specifically, a second side mounting plate 23 is integrally provided on one side of the I-beam 2. The second side mounting plate 23 is locked to the first side mounting plate 51 by multiple bolts, so that the single pipe embedded part 5 can play a limiting support role for the I-beam 2. Since the inner sliding frame 30 and the outer sliding frame 31 themselves have the function of supporting the I-beam 2 when they are fitted on the I-beam 2, and multiple mounting holes 21 are opened on the upper and lower sides of the I-beam 2 respectively, the inner sliding frame 30 and the outer sliding frame 31 are locked to the mounting holes 21 by bolts, which further fixes the inner sliding frame 30 and the outer sliding frame 31. Under the action of the triangular support structure, even if all the inner sides of the I-beam 2 break or detach, it is difficult for them to tilt or slide on the inner sliding frame 30 and the outer sliding frame 31. Meanwhile, multiple concave sliders 6 are slidably installed on the convex edges on the upper and lower sides of the I-beam 2. A crossbeam plate 61 is installed on the outside of the concave slider 6. The two ends of the crossbeam plate 61 are respectively placed between the concave sliders 6 on the upper side of the two I-beams 2. In this way, the crossbeam plate 61 can be removed and replaced individually in the future without replacing the entire long plate. The crossbeam plate 61, the concave sliders 6 and the mounting holes 21 are locked and fixed with bolts. In this way, even if the inner sliding frame 30 and the outer sliding frame 31 are not locked, each locked concave slider 6 can still limit the inner sliding frame 30 and the outer sliding frame 31, thereby improving the safety of use.
[0022] Furthermore, a groove 22 is provided in the middle of the I-beam 2, and an outer sliding bracket 7 is provided in the groove 22. The outer sliding bracket 7 is supported by the foundation. The outer sliding bracket 7 includes a sliding plate 71 that is slidably embedded in the inner side of the groove 22. Both the I-beam 2 and the sliding plate 71 have pin holes in their middle for fixing the sliding plate 71. The pins are inserted into the pin holes of the I-beam 2 and the sliding plate 71 for limiting the position. A threaded tube 72 is vertically fixed to the outer end of the sliding plate 71. A vertical screw rod 73 is threaded through the middle of the threaded tube 72. The vertical screw rod 73 is located above and below the threaded tube 72. The threaded section has an upper tightening nut 74 and a lower tightening nut 75. Rubber pads for tightening the upper and lower sides of the threaded tube 72 are provided on opposite sides of the upper tightening nut 74 and the lower tightening nut 75. The bottom end of the vertical screw 73 is supported by the foundation surface. The auxiliary support of the vertical screw 73 can further prevent the I-beam 2 from tilting and keep the I-beam 2 in a horizontal support state. Moreover, the upper and lower ends of the vertical screw 73 are respectively provided with mutually compatible inserts and slots. In this way, multiple vertical screws 73 can be inserted and spliced together to form a whole, and the I-beams 2 of different layers can be supported synchronously.
[0023] Meanwhile, the upper sides of the crossbeams 61 on both sides of the I-beam 2 are fixed to the scaffold 8 with bolts. A reinforcing screw 62 is installed through the middle of the crossbeam 61 on the lower side of the I-beam 2, passing through the two opposing crossbeams 61 and then threadedly connected to the bottom of the scaffold 8 for secondary fixation. This double connection not only ensures the stability of the scaffold 8 but also facilitates the later disassembly and replacement of individual crossbeams 61. A handwheel can also be integrated into the bottom of the reinforcing screw 62 for convenient rotation. The scaffold 8 includes multiple vertically arranged uprights 81 and hollowed-out buckles 82 on the upper and lower sides of the uprights 81. Side bars 83 are interlocked between the hollowed-out buckles 82, forming a rectangular frame. A lower threaded tube 84 is integrated into the bottom of the uprights 81, and this lower threaded tube 84 is threadedly connected to the top of the reinforcing screw 62. A construction method for a basket-link cantilevered external scaffold includes the following steps: After laying the formwork frame 1, horizontal reinforcing bars 101, and U-shaped reinforcing bars 102, holes are drilled in the formwork frame 1 using a drilling machine for inserting and installing double-pipe embedded parts 4 and single-pipe embedded parts 5. The single-pipe embedded part 5 and the two double-pipe embedded parts 4 are inserted into the corresponding holes, with both positioned on one side of the horizontal reinforcing bars 101 and U-shaped reinforcing bars 102. It is important to note that the two outer sleeves 41 of the double-pipe embedded part 4 must be secured to the upper and lower sides of the horizontal reinforcing bars 101 to ensure proper support. The high-strength double-pipe embedded part 4 provides strong support to the wall and is less prone to vertical displacement and loosening under later stress. After the single-pipe embedded part 5 and the double-pipe embedded part 4 are placed, the high-strength bolt rod 42 needs to be continuously screwed into the outer sleeve 41. In this way, the high-strength bolt rod 42 can push the ball 46 outward, causing the inner elastic ring plate 45 to undergo adaptive elastic deformation. Then, after the ball 46 moves outward, it simultaneously pushes one end of the rotating rod 44 to rotate outward and unfold. After this unfolded rotating rod 44 is bonded to the concrete later, it is not easy for the outer sleeve 41 to detach, ensuring the stability of the double-pipe embedded part 4 and the single-pipe embedded part 5 in use. After the laying is completed, concrete is poured into the template frame 1 to form a whole with the transverse steel bar 101, U-shaped steel bar 102, single pipe embedded part 5 and double pipe embedded part 4. At this time, the second side mounting plate 23 of one end of the I-beam 2 is aligned with the first side mounting plate 51 connected by the high-strength bolt rod 42 of the single pipe embedded part 5, and is locked and fixed by bolts. Then, the inner sliding frame 30, the first set of two concave sliders 6, the outer sliding frame 31 and the second set of two concave sliders 6 are slidably mounted on the I-beam 2 in sequence. At this time, the inner sliding frame 30, the concave sliders 6 and the outer sliding frame 31 can be flexibly adjusted to the corresponding positions, and then locked on the mounting hole 21 of the I-beam 2 by bolts. Next, the upper vertical basket pull rod 301 and the lower vertical basket pull rod 302 are hinged to the upper and lower sides of the inner sliding frame 30, respectively. Meanwhile, the upper inclined basket pull rod 311 and the lower inclined basket pull rod 312 are hinged to the upper and lower sides of the outer sliding frame 31. Then, the top ends of the upper vertical basket pull rod 301 and the upper inclined basket pull rod 311 are rotatably connected to the outer ends of the two high-strength bolt rods 42 of the upper double-pipe embedded part 4, thus forming an upper triangular support structure. The ends of the lower vertical basket pull rod 302 and the lower inclined basket pull rod 312 are rotatably connected to the outer ends of the two high-strength bolt rods 42 of the lower double-pipe embedded part 4, thus forming a lower triangular support structure. Therefore, through... The stable support structure of the double-pipe embedded part 4 and the single-pipe embedded part 5, combined with the upper and lower triangular support structures, provides stable tension and support for the I-beam 2, greatly improving the structural stability of the cantilever. Subsequently, before installing the scaffold 8, the positions of the four concave sliders 6 can be adjusted, and then the four crossbeam plates 61 are overlapped between the four concave sliders 6 of the two I-beams 2. This overlap allows each crossbeam plate 61 to bear force independently, and facilitates disassembly and replacement later. The scaffold 8 is then installed on the upper side of the crossbeam plates 61. During installation, the four uprights 81 are aligned with the middle positions of the four sets of upper crossbeam plates 61, and then bolts are used for securing them. The scaffolding 8 is first fixed, and then reinforced by screws 62 that pass through the four lower crossbeams 61 and threaded into the lower threaded tubes 84 at the bottom of the uprights 81. This provides secondary reinforcement and fixation to the bottom of the scaffolding 8, making the scaffolding 8 not only structurally more stable but also easier to assemble and disassemble. Hollowed-out buckles 82 are also provided between the four uprights 81, facilitating the connection of the buckles at the ends of the side poles 83. Finally, an external sliding bracket 7 can be added depending on the usage requirements or environment. For example, when installing on the I-beams 2 near the ground level, the sliding plate 71 can be pulled outwards to a corresponding distance, and then the vertical screw 73 can be screwed into the threaded tube 72. The vertical screw 73 is adjusted to its corresponding height, allowing its bottom to directly contact the ground surface for auxiliary support. Then, the rubber pads on opposite sides of the upper tightening nut 74 and lower tightening nut 75 are adjusted to tighten the screw tube 72, which helps prevent the vertical screw 73 from rotating. The auxiliary support of the vertical screw 73 can further prevent the I-beam 2 from tilting, keeping the I-beam 2 horizontal and improving the stability of the foundation support of the lower-level I-beam 2. Moreover, the upper and lower ends of the vertical screw 73 are respectively equipped with mutually compatible inserts and slots, so that multiple vertical screws 73 can be interlocked and spliced into a whole to provide synchronous support for the I-beams 2 of different layers, improving the support effect.
