Description

Technical Field

[0001] This application belongs to the field of scaffolding technology, specifically relating to a disc-lock scaffolding for building operations. Background Technology

[0002] With the acceleration of urbanization and the continuous increase in the number of high-rise buildings, scaffolding, as a key facility for ensuring construction safety, promoting project progress, and ensuring construction quality, plays an increasingly prominent role in modern construction. Common types of scaffolding currently on the market include coupler-type steel pipe scaffolding, frame-type steel pipe scaffolding, cup-lock scaffolding, and disc-lock scaffolding. Among them, disc-lock scaffolding is widely used due to its excellent ease of assembly and disassembly.

[0003] Currently, conventional disc-lock scaffolding commonly adopts designs similar to those in applications 202323053561.1 and 202411403923.1. This involves installing connecting discs at intervals on the uprights, with several holes longitudinally distributed around their axis. The horizontal bars have symmetrically placed, perforated interlocking plates at both ends. The connection between the uprights and horizontal bars is achieved by placing the connecting discs between the upper and lower interlocking plates and inserting pins. Furthermore, to enhance the stability of the entire scaffolding system, the other end of the horizontal bars fixed around the uprights is also connected to other uprights in the same way. This multi-directional, multi-layered connection method not only ensures the robustness of the connection between individual uprights and horizontal bars but also significantly improves the stability and safety of the entire scaffolding structure, thus meeting the requirements for efficient and reliable support systems during high-rise building construction.

[0004] However, please refer to patents with application numbers 202510319850.6 and 202322421784.2. In existing disc-lock scaffolding structures, the construction platform is typically erected and fixed above opposing horizontal bars. This results in the gravity generated during construction being initially borne by the horizontal bars and then further transferred to the connecting plate connected to them. Because the force is concentrated at the connection between the horizontal bar and the connecting plate, the side of the connecting plate closer to the horizontal bar bears more load, leading to a phenomenon of concentrated force on one side. As mentioned above, to ensure the overall stability and connection reliability of the disc-lock scaffolding structure, the connecting plate typically needs at least four mounting holes to achieve a secure connection with components such as the horizontal bars. However, the presence of these mounting holes weakens the material strength of the connecting plate to some extent, making it a weak point in the structure. Simultaneously, because the construction platform is often fixed above the horizontal bars, the connecting plate bears more load on the side connected to the horizontal bars, creating an unfavorable unilateral force condition. The combined effect of uneven stress and weakened structural strength makes the connecting plate in this part more prone to deformation or damage during actual use, thus posing a potential risk to the safety and stability of the entire scaffolding system. Utility Model Content

[0005] The purpose of this application is to provide a disc-lock scaffolding with high overall stability, convenient disassembly and installation, and excellent mechanical performance of the connecting plate for long-term use. This is achieved through the following technical solution:

[0006] A disc-lock scaffold includes uprights, connecting discs spaced apart along the axial direction of the uprights and sleeved thereon, horizontal bars connected to the corresponding connecting discs to connect two uprights, and a construction platform erected on the horizontal bars; the uprights are also provided with locking areas distributed above and connected to the connecting discs; the two ends of the horizontal bars are formed with mounting portions, the lower surface of the mounting portions is in contact with the upper surface of the connecting discs, and the mounting portions are also provided with locking holes for housing the locking areas within the mounting portions; the uprights are connected to at least one set of horizontal bars that are perpendicular to each other in projection on a horizontal plane.

[0007] Preferably, apart from the outermost uprights, the remaining uprights are connected to each other by at least four surrounding uprights via crossbars.

[0008] Preferably, the crossbar includes an overlapping portion disposed between the mounting portions; the mounting portion includes a preliminary mounting section extending outward along the end of the overlapping portion to surround the outer periphery of the locking area of ​​the upright, and a secondary mounting section that is slidably locked to both ends of the preliminary mounting section to form the locking hole.

[0009] Preferably, the preliminary installation sections are respectively arranged on both sides of the central axis of the crossbar; and the length of the preliminary installation section is greater than the length of the secondary installation section.

[0010] Preferably, the lower surface of the mounting part is formed with at least one set of mounting lugs that penetrate the connecting plate, and the lower ends of the mounting lugs are connected to each other by limiting members, which abut against the lower surface of the connecting plate when the crossbar moves upward.

[0011] Preferably, the construction platform is provided with downwardly extending plug rods on opposite sides, and the upper surface of the crossbar is provided with positioning pin holes that cooperate with the plug rods.

[0012] Preferably, the construction platform includes a central panel with a hollow structure and a frame structure surrounding the central panel. The mechanical strength of the frame structure is greater than that of the central panel, and the plug-in rod is located at the position of the frame structure.

[0013] Preferably, the pole comprises multiple splicable pole segments, and each pole segment has an external threaded connector at its upper end and a matching internal threaded connector at its lower end; the connecting plate is disposed between the external threaded connector and the internal threaded connector of any pole segment.

[0014] Preferably, the bottom of the pole is also provided with a base for fixing it to the ground, and the base is connected to the internal thread joint of the pole frame section through an external thread provided thereon.

[0015] Compared with the prior art, this application has the following beneficial effects:

[0016] This application addresses the issue of unilateral stress concentration caused by the direct application of construction loads to a localized area of ​​the connecting plate in traditional scaffolding by placing the integrated structure at both ends of the horizontal bar on the upper part of the connecting plate. This effectively improves the uniformity of stress distribution and structural durability of the connecting plate. Furthermore, the end of the horizontal bar is equipped with a mounting part featuring a locking hole that engages with a locking area on the upright, effectively limiting the displacement or rotation of the horizontal bar during use and ensuring a stable connection between the horizontal bar and the upright. In addition, at least one set of horizontal bars with mutually perpendicular projections on the horizontal plane is connected to the same upright. This structural design allows the upright to form a spatially stable structure with at least two surrounding uprights, meeting the overall structural stability requirements without needing to connect to uprights in all four directions. This ensures safety and significantly improves the efficiency of scaffolding installation and dismantling.

[0017] This application employs a split-type installation structure design, enabling the crossbar to be more easily and quickly connected and disassembled with the upright, significantly improving construction efficiency. Furthermore, the preliminary installation sections at both ends of the crossbar are symmetrically positioned on both sides of its central axis, effectively dispersing the force exerted by the crossbar on the connecting plate while achieving rapid installation, thus avoiding uneven stress that might result from a split structure.

[0018] This application provides mounting lugs that penetrate the connecting plate on the lower surface of the crossbar mounting section, and connects a limiting member between the lower ends of the lugs. This allows the crossbar to abut against the lower surface of the connecting plate through the limiting member when subjected to an upward force, thereby effectively limiting its displacement in the longitudinal direction. This limiting structure cooperates with the locking hole at the end of the crossbar and the locking area on the upright, achieving multi-directional limiting and stable connection of the crossbar in both the horizontal and vertical directions.

[0019] This application utilizes downward-extending plug-in rods on opposite sides of the construction platform, with corresponding positioning pin holes on the upper surface of the crossbars. This allows the construction platform to be quickly positioned and erected on the crossbars via a plug-in connection. This structural design not only simplifies the installation and disassembly process of the construction platform, significantly improving erection efficiency, but also enhances the flexibility of the platform's placement by providing multiple optional positioning pin holes on the crossbars, enabling it to be flexibly adjusted and adapted according to actual construction needs.

[0020] The construction platform described in this application includes a central panel with a hollow structure in the middle, and a frame structure surrounding the central panel. The frame structure has higher mechanical strength than the central panel and is used to bear the main load and improve the stability of the overall structure. The hollow design reduces the weight of the construction platform while effectively improving light transmission, allowing natural and artificial lighting at the construction site to better penetrate the platform, facilitating observation and operation of the structure below by construction personnel.

[0021] This application utilizes multiple detachable and splicable frame segments for the uprights, with external threaded joints at the upper end and matching internal threaded joints at the lower end of each segment. This ensures the uprights offer excellent ease of assembly and disassembly while maintaining structural strength, facilitating transportation, installation, and reuse. Furthermore, placing a connecting plate between the external and internal threaded joints of any frame segment positions the connecting plate at a critical stress-bearing point during upright splicing. This enhances the connection rigidity and stress uniformity between the uprights and horizontal members, thereby improving the overall structural strength and safety performance of the disc-lock scaffolding.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Those skilled in the art will be able to implement the present invention based on these descriptions. Furthermore, the embodiments of the present invention described below are generally only a part of the embodiments of the present invention, and not all of the embodiments. Therefore, all other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Example

[0030] A disc-lock scaffold includes multiple uprights 100, each upright 100 including a base 120 and multiple frame segments 110 disposed on the base 120. Each frame segment 110 has an external threaded connector 111 at its upper end and a matching internal threaded connector 112 at its lower end. Adjacent frame segments 110 can be detachably spliced ​​by threaded connection.

[0031] Along the axial direction of the upright 100, multiple connecting discs 200 are welded at intervals on the outer periphery of the upright 100. Each connecting disc 200 is arranged in a sheet-like annular structure with the corresponding support segment 110 as its axis. In this embodiment, to further enhance the structural stability of the area where the connecting disc 200 is located, the connecting disc 200 is positioned between the external threaded joint 111 and the internal threaded joint 112 of each support segment 110.

[0032] The disc-lock scaffold also includes a horizontal bar 300, with mounting portions 310 formed at both ends of the horizontal bar 300 and an overlap portion 320 formed between the mounting portions 310. The vertical pole 100 is also provided with locking areas distributed above and connected to the connecting plate 200. The lower surface of the mounting portion 310 is in contact with the upper surface of the connecting plate 200, and the mounting portion 310 is also provided with locking holes 311 for housing the locking areas within the mounting portion 310. Specifically, in this embodiment, the mounting portion 310 includes a preliminary mounting section 312 extending outward along the end of the overlap portion 320 to surround the outer periphery of the locking area of ​​the vertical pole 100, and a secondary mounting section 313 that is slidably and lockingly connected to both ends of the preliminary mounting section 312 to form the locking holes 311. To further increase the stability of the crossbar 300 installation, the preliminary installation sections 312 are respectively arranged on both sides of the central axis of the crossbar 300; and the length of the preliminary installation section 312 is greater than the length of the secondary installation section 313. To prevent the crossbar 300 from moving in the longitudinal direction of the upright 100, in this embodiment, the lower surface of the installation part 310 is formed with at least one set of installation ear plates 314 that penetrate the connecting plate 200. The lower ends of the installation ear plates 314 are connected to each other with limiting members 315. When the crossbar 300 moves upward, the limiting members 315 abut against the lower surface of the connecting plate 200.

[0033] In this embodiment, in addition to the uprights 100 located on the outer periphery of the disc-lock scaffold, the horizontal bars 300 on the upright group formed by the four uprights 100 are arranged in parallel on the same horizontal plane, and the projections of these horizontal bars 300 on the horizontal plane are perpendicular to each other. Of course, in other embodiments, a group of diagonally arranged uprights 100 can be connected by horizontal bars 300. In addition, the disc-lock scaffold also includes a construction platform 400 erected on the horizontal bars 300; the construction platform 400 has downwardly extending plug-in rods 410 on opposite sides, and the upper surface of the horizontal bars 300 has positioning pin holes 321 that cooperate with the plug-in rods 410. The construction platform 400 includes a central panel 420 with a hollow structure, and a frame structure 430 surrounding the central panel 420. The mechanical strength of the frame structure 430 is greater than that of the central panel 420, and the plug-in rods 410 are located at the position of the frame structure 430.

[0034] During installation, the base 120 is first fixed to the ground or supporting structure according to the predetermined construction position. Then, the pole frame sections 110 are screwed together in sequence, so that adjacent pole frame sections 110 are threadedly connected through external threaded joints 111 and internal threaded joints 112. The connecting plate 200 is welded between the external threaded joints 111 and internal threaded joints 112 of each pole frame section 110, ensuring that it is located outside the splicing part of the upright 100 to enhance structural stability. After the upright 100 is assembled, the initial installation section 312 of the crossbar 300 is placed outside the locking area on the upright 100, and the secondary installation section 313 is slidably engaged with both ends of the initial installation section 312 to form a complete locking hole structure, ensuring a stable connection between the crossbar 300 and the upright 100. Meanwhile, the mounting lugs 314 at the bottom of the crossbar 300 penetrate the connecting plate 200, and a limiting member 315 is connected between the lower ends of the mounting lugs 314, so that when the crossbar 300 tends to move upward, it abuts against the lower surface of the connecting plate 200, thereby achieving a longitudinal limiting function. Finally, the construction platform 400 is hoisted to the designated height, and the plug-in rods 410 on its opposite sides are aligned with the positioning pin holes 321 provided on the upper surface of the crossbar 300 and inserted to complete the positioning, thereby realizing the rapid erection of the construction platform 400 on the crossbar 300.
