Description

Technical Field

[0001] This invention relates to the field of engineering construction technology, and in particular to a scaffolding connecting fastener and scaffolding. Background Technology

[0002] In the construction industry, scaffolding is an essential temporary structure used to provide a working platform and safety for construction workers. However, current scaffolding systems all require additional tools for erection. For example, disc-lock scaffolding requires hammering the pins, steel pipe coupler scaffolding requires wrenches to tighten the couplers, and cup-lock and ring-lock scaffolding systems all require tightening certain parts to ensure the stability of the scaffolding.

[0003] These traditional erection methods are prone to problems during construction, such as insufficient tightening, leading to quality issues and potential safety accidents. Furthermore, the frequent use of hammers, wrenches, and other tools by construction workers not only increases the complexity of the work but also increases the risk of tools falling and injuring people, posing additional safety risks to the construction site.

[0004] Furthermore, due to the characteristics of the joint connections, the existing scaffolding system can only withstand pressure and is difficult to withstand tension. This imposes many restrictions on the use of the scaffolding, making it impossible to carry out hoisting operations or handle structures that require hoisting. This greatly reduces the flexibility of the scaffolding and causes great inconvenience to construction, increasing the difficulty of construction.

[0005] Finally, existing scaffolding systems all require secondary hammering or dismantling during dismantling. This inconvenient dismantling method not only easily damages various components and reduces their reusability, but also easily causes danger and hinders the smooth progress of construction.

[0006] Therefore, it is necessary to provide a scaffolding connection coupler and scaffolding to solve the above-mentioned problems existing in the prior art. Summary of the Invention

[0007] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a scaffolding connecting coupler and scaffolding to solve the technical problems of increased construction difficulty and cost and reduced construction efficiency in the erection, use and dismantling process of the prior art.

[0008] To solve the above-mentioned technical problems, the present invention provides a scaffolding connecting fastener, comprising:

[0009] The first swivel fastener includes a base, a first protrusion, a first recess, and a plurality of limiting holes. The first protrusion and the first recess are connected together and are both disposed on the end face of the base. A positioning hole is provided at the center of the base, penetrating the base. The plurality of limiting holes are disposed on the base, respectively penetrating the base around the positioning hole.

[0010] The second rotary fastener includes a base, a second protrusion, a second recess, a positioning member, and multiple elastic limiting members. The second protrusion and the second recess are connected in combination and are both disposed on the end face of the base. The second protrusion and the first recess are adapted to each other, and the second recess is adapted to the first protrusion. The positioning member is disposed at the center of the base and is adapted to the positioning hole. Multiple elastic limiting members are disposed around the positioning member on the base and are adapted to the corresponding limiting holes.

[0011] The scaffolding connecting fastener provided by this invention has the following beneficial effects:

[0012] By designing a first protrusion that matches a second recess, and a first recess that matches a second protrusion, with positioning holes corresponding to positioning elements and multiple elastic limiting elements corresponding to multiple limiting holes, convenient assembly and disassembly of the first and second rotary fasteners are achieved. Specifically, when assembling the first and second rotary fasteners, the positioning element is first inserted into the positioning hole as a fixed center, facilitating the rotation of the second rotary fastener relative to the first rotary fastener. At this time, each elastic limiting element is in an elastically compressed state. Then, the second rotary fastener is rotated until each elastic limiting element is engaged in the corresponding limiting hole, at which point the elastic limiting element returns to its natural elongated state, thus ensuring a stable connection between the first and second rotary fasteners. When removing the first and second rotary fasteners, simply pressing down the elastic limiting element separates them, greatly simplifying the disassembly process, improving construction efficiency, and reducing construction costs.

[0013] Furthermore, the first recess includes a protrusion and a slot, and the height of the first protrusion is higher than that of the protrusion; the slot is formed by the first protrusion and the protrusion.

[0014] Furthermore, the base is provided with mounting holes corresponding to the elastic limiting member.

[0015] Furthermore, the elastic limiting member includes an elastic part and a limiting post. One end of the elastic part is fixedly connected to the bottom surface of the mounting hole, and the other end is fixedly connected to one end of the limiting post.

[0016] Furthermore, the base and the pedestal are circular in shape.

[0017] Furthermore, the shape of the first protrusion and the first depression combined together, as well as the shape of the second protrusion and the second depression combined together, are both the shape of a Tai Chi Yin-Yang fish.

[0018] To address the aforementioned technical problems, the present invention also provides a scaffolding, comprising:

[0019] Multiple scaffolding connecting couplers as described above;

[0020] Multiple top adjustment components;

[0021] Multiple first vertical support components, the bottom of each of the top adjustment components is connected to one end of the corresponding first vertical support component via a corresponding scaffolding connecting fastener;

[0022] Multiple first connecting components, each of which is connected at both ends to two corresponding first vertical support components via corresponding scaffolding connecting fasteners;

[0023] Multiple first arc-shaped support components are provided, with two adjacent first arc-shaped support components connected by corresponding scaffolding connecting fasteners; each first arc-shaped support component is connected to a corresponding first vertical support component by a corresponding scaffolding connecting fastener.

[0024] Multiple second connecting components, one end of each second connecting component being connected to the first arc-shaped support component via a corresponding scaffolding connecting fastener;

[0025] Multiple inclined support components, each of the inclined support components being disposed between two adjacent second connecting components;

[0026] Multiple second arc-shaped support components, each of which is connected to the other end of a second connecting component via a corresponding scaffolding connecting fastener;

[0027] Multiple second vertical support components, one end of each second vertical support component is connected to the second arc-shaped support component via a corresponding scaffolding connecting fastener;

[0028] Multiple hoisting support assemblies, the top of each of which is connected to the other end of the second vertical support assembly via a corresponding scaffolding connecting fastener.

[0029] Furthermore, each of the first vertical support assembly and the second vertical support assembly includes a support rod and a support connection portion. One end of the support rod is connected to the top adjustment assembly or the hoisting support assembly via a scaffolding connecting fastener, and the other end of the support rod is connected to the support connection portion via a scaffolding connecting fastener. The support connection portion includes a rotating shaft.

[0030] Furthermore, each of the first arc-shaped support assembly and the second arc-shaped support assembly includes an arc-shaped component, and a rotating platform is provided at the middle position of the arc-shaped component, with the rotating shaft connected to the rotating platform.

[0031] Furthermore, each of the inclined support components includes a tie rod and two connecting bolts, the two connecting bolts being movably connected to both ends of the tie rod, and each connecting bolt being connected to one end of the rotating shaft via a scaffolding connecting fastener.

[0032] The beneficial effects of the scaffolding provided by this invention are the same as those of the scaffolding connecting fasteners described above. Attached Figure Description

[0049] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0050] It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the implementation of the invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the disclosed technical content. The following detailed description should not be considered restrictive, and the scope of the embodiments of this application is limited only by the claims of the published patents. The terminology used herein is for describing specific embodiments only and is not intended to limit the application. Spatial terms such as "upper," "lower," "left," "right," "below," "below," "lower part," "above," "upper part," etc., may be used in the text to illustrate the relationship between one element or feature shown in the figures and another element or feature.

[0051] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," and "holding" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

Thus, “A, B, or C” or “A, B, and / or C” means “any one of: A; B; C; A and B; A and C; B and C; A, B, and C.” Exceptions to this definition arise only when combinations of elements, functions, or operations are inherently mutually exclusive in some manner.

[0053] like Figures 1-6 As shown, an embodiment of the present invention provides a scaffolding connecting coupler 100, including: a first swivel coupler 101 and a second swivel coupler 102. Through the cooperation of the first swivel coupler 101 and the second swivel coupler 102, the various components used for erecting scaffolding are securely connected, greatly simplifying the erection process while ensuring the stability of the scaffolding.

[0054] The first swivel fastener 101 includes a base 1011, a first protrusion 1012, a first recess 1013, and a plurality of limiting holes 1014. The first protrusion 1012 and the first recess 1013 are connected together and are both disposed on the end face of the base 1011. A positioning hole 1011a is provided at the center of the base 1011, penetrating the base 1011. The plurality of limiting holes 1014 are disposed on the base 1011, surrounding the positioning hole 1011a and penetrating the base 1011. The second swivel fastener 102 includes a base 1021, a second protrusion 1022, a second recess 1023, a positioning member 1024, and a plurality of elastic limiting members 1025. The second protrusion 1022 and the second recess 1023 are combined and connected, and both are disposed on the end face of the base 1021. The second protrusion 1022 is adapted to the first recess 1013, and the second recess 1023 is adapted to the first protrusion 1012. The positioning member 1024 is disposed at the center of the base 1021 and is adapted to the positioning hole 1011a. A plurality of elastic limiting members 1025 are disposed around the positioning member 1024 on the base 1021 and are adapted to the corresponding limiting holes 1014.

[0055] By designing the first protrusion 1012 to fit the second recess 1023, the first recess 1013 to fit the second protrusion 1022, and the positioning hole 1011a to correspond to the positioning member 1024, and the multiple elastic limiting members 1025 to correspond to the multiple limiting holes 1014, convenient assembly and disassembly of the first rotary fastener 101 and the second rotary fastener 102 are achieved. Specifically, when assembling the first rotary fastener 101 and the second rotary fastener 102, the positioning member 1024 is first inserted into the positioning hole 1011a as a fixing center, facilitating the assembly and disassembly of the second rotary fastener 102. The first rotating fastener 101 is rotated relative to the second rotating fastener 102. At this time, each elastic limiting member 1025 is in an elastically compressed state. The second rotating fastener 102 is then rotated until each elastic limiting member 1025 is engaged in the corresponding limiting hole 1014. The elastic limiting member 1025 returns to its natural extended state, thereby making the first rotating fastener 101 and the second rotating fastener 102 securely connected. When the first rotating fastener 101 and the second rotating fastener 102 are removed, they can be separated simply by pressing down the elastic limiting member 1025, which greatly simplifies the removal process, improves construction efficiency, and reduces construction costs.

[0056] Specifically, the contour formed by the combination of the first protrusion 1012 and the first recess 1013 is formed by a smooth transition from a higher slope to a lower slope. Similarly, the contour formed by the combination of the second protrusion 1022 and the second recess 1023 is also formed by a smooth transition from a higher slope to a lower slope, and is adapted to the slopes of the first recess 1013 and the first protrusion 1012, respectively. This smooth slope design provides a smooth guide path for the rotary fastening. The second protrusion 1022 is smoothly guided along the slope to the corresponding position of the first recess 1013, reducing assembly resistance and achieving reverse self-locking. This ensures that when the first rotary fastener 101 and the second rotary fastener 102 are assembled, the curved surfaces of the first protrusion 1012 and the second recess 1023, as well as the first recess 1013 and the second protrusion 1022, can fit tightly together, guaranteeing the stability of the connection.

[0057] For example, the number of elastic limiting members 1025 is designed to be two, which saves material costs and has a reasonable spatial layout design while ensuring a tight connection between the first rotating fastener 101 and the second rotating fastener 102.

[0058] For example, both the first swivel fastener 101 and the second swivel fastener 102 are made of Q355 steel.

[0059] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the first recess 1013 includes a protrusion 1013a and a slot 1013b. The height of the first protrusion 1012 is higher than that of the protrusion 1013a. The slot 1013b is formed by the first protrusion 1012 and the protrusion 1013a. Specifically, by designing the height of the first protrusion 1012 to be higher than that of the protrusion 1013a, the first protrusion 1012 and the protrusion 1013a form a groove 1013b. When the second swivel fastener 102 is rotated relative to the first swivel fastener 101, the second protrusion 1022 is inserted into the groove 1013b along the inclined surface until it fits against the inner wall of the first protrusion 1012, effectively achieving radial and axial locking. This further ensures the stability of the connection between the first swivel fastener 101 and the second swivel fastener 102, while also enabling the scaffolding connecting fastener 100 to withstand tensile forces, thus expanding the application range of the scaffolding structure erected using the scaffolding connecting fastener 100.

[0060] like Figure 5 and Figure 6As shown, in some embodiments of the present invention, the base 1021 is provided with mounting holes 1021a corresponding to the elastic limiting members 1025. Correspondingly, the number of mounting holes 1021a on the base 1021 corresponds to the number of elastic limiting members 1025. For example, the number of mounting holes 1021a is also two, which are used to install the corresponding elastic limiting members 1025, so as to reasonably plan the space layout.

[0061] like Figure 1 and Figure 6 As shown, in some embodiments of the present invention, the elastic limiting member 1025 includes an elastic part 1025a and a limiting post 1025b. One end of the elastic part 1025a is fixedly connected to the bottom surface of the mounting hole 1021a, and the other end is fixedly connected to one end of the limiting post 1025b. With the cooperation of the elastic part 1025a and the limiting post 1025b, when the positioning member 1024 is inserted into the positioning hole 1011a but before the second rotating fastener 102 is rotated, the elastic part 1025a is in an elastically compressed state, driving the limiting post 1025b to move inward toward the mounting hole 1021a. Rotating the second rotating fastener 102 until the limiting post 1025b engages in the corresponding limiting hole 1014, the elastic part 1025a naturally extends and retracts to its initial state, driving the limiting post 1025b to move away from the mounting hole 1021a, so that the limiting post 1025b is in the corresponding limiting hole 1014, thus achieving a tight connection between the first rotating fastener 101 and the second rotating fastener 102. Furthermore, when removing the first rotating fastener 101 and the second rotating fastener 102, simply press the limiting post 1025b to separate them; this is simple, convenient, and improves construction efficiency. For example, the elastic part 1025a is a spring.

[0062] like Figure 1 and Figure 4 As shown, in some embodiments of the present invention, the base 1011 and the base 1021 are circular in shape. By designing the base 1011 and the base 1021 to be circular, it is convenient to rotate and assemble them.

[0063] like Figure 3 and Figure 5As shown, in some embodiments of the present invention, the shapes of the first protrusion 1012 and the first recess 1013 after being combined and connected, and the shapes of the second protrusion 1022 and the second recess 1023 after being combined and connected, are both Tai Chi Yin-Yang fish shapes. Specifically, a first rotating fastener 101 is composed of a combination structure of two parts: the first protrusion 1012 and the first recess 1013, thus the shape of the first rotating fastener 101 is Tai Chi Yin-Yang fish; similarly, a second rotating fastener is composed of a combination structure of two parts: the second protrusion 1022 and the second recess 1023, thus the shape of the second rotating fastener 102 is also Tai Chi Yin-Yang fish. By designing the shapes of the first rotating fastener 101 and the second rotating fastener 102 as Tai Chi Yin-Yang fish shapes, during the rotational fastening process, the corresponding contours between the two always guide each other and fit closely, forming a progressive locking mechanism, thereby improving the smoothness of the assembly of the first rotating fastener 101 and the second rotating fastener 102.

[0064] It should be noted that the scaffolding connecting fastener 100 of the present invention can be used for various structural supports of scaffolding as a connecting node.

[0065] like Figures 1-14 As shown, embodiments of the present invention also provide a scaffold, including: a plurality of scaffold connecting fasteners 100 as described above, a plurality of top adjustment components 110, a plurality of first vertical support components 120, a plurality of first connecting components 130, a plurality of first arc-shaped support components 140, a plurality of second connecting components 150, a plurality of inclined support components 160, a plurality of second arc-shaped support components 170, a plurality of second vertical support components 180, and a plurality of hoisting support components 190.

[0066] The bottom of each top adjusting component 110 is connected to one end of each corresponding first vertical support component 120 via a corresponding scaffolding connecting fastener 100. Both ends of each first connecting component 130 are connected to two corresponding first vertical support components 120 via corresponding scaffolding connecting fasteners 100. Two adjacent first arc-shaped support components 140 are connected via corresponding scaffolding connecting fasteners 100. Each first arc-shaped support component 140 is connected to a corresponding first vertical support component 120 via a corresponding scaffolding connecting fastener 100. One end of each second connecting component 150 is connected to a first arc-shaped support component 140 via a corresponding scaffolding connecting fastener 100. Each diagonal support component 160 is positioned between two adjacent second connecting components 150. Each second arc-shaped support component 170 is connected to the other end of a second connecting component 150 via a corresponding scaffolding connecting fastener 100. One end of each second vertical support component 180 is connected to a second arc-shaped support component 170 via a corresponding scaffolding connecting fastener 100. The top of each hoisting support assembly 190 is connected to the other end of the second vertical support assembly 180 via a corresponding scaffolding connecting fastener 100.

[0067] The various top adjustment components 110, first vertical support components 120, first connecting components 130, first arc-shaped support components 140, second connecting components 150, diagonal support components 160, second arc-shaped support components 170, second vertical support components 180, and hoisting support components 190 are connected horizontally, vertically, or diagonally using scaffolding connecting couplers 100. Each component can be locked in place simply by pressing and rotating, thus forming a stable scaffolding system without the need for additional external force. Furthermore, the use of scaffolding connecting couplers 100 as connection nodes allows the system to withstand both pressure and tension, expanding the usability of the scaffolding structure, ensuring balanced stress distribution, facilitating installation and dismantling, greatly improving construction efficiency, and reducing safety hazards.

[0068] like Figure 8 , Figure 9 and Figure 10 As shown and in conjunction with reference Figure 1 In some embodiments of the present invention, each first vertical support assembly 120 and second vertical support assembly 180 includes a support rod 121 and a support connection portion 122. One end of the support rod 121 is connected to the top adjustment assembly 110 or the hoisting support assembly 190 via a scaffolding connecting fastener 100, and the other end of the support rod 121 is connected to the support connection portion 122 via the scaffolding connecting fastener 100. The support connection portion 122 includes a rotating shaft 1221. Further, the support connection portion 122 also includes a connecting rod 1222, with the rotating shaft 1221 disposed at one end of the connecting rod 1222. The support connection portion 122 can rotate at any angle to ensure that the upper structure remains vertical at all times.

[0069] For example, a first swivel fastener 101 is welded to one end of the support rod 121. Correspondingly, a second swivel fastener 102 is welded to the bottom of the top adjustment assembly 110 and the top of the hoisting support assembly 190. The support rod 121 and the top adjustment assembly 110 or the hoisting support assembly 190 are fastened together by the cooperation of the first swivel fastener 101 at one end of the support rod 121 and the second swivel fastener 102 at the bottom of the top adjustment assembly 110 or the top of the hoisting support assembly 190. A second swivel fastener 102 is welded to the other end of the support rod 121, and a first swivel fastener 101 is welded to the other end of the connecting rod 1222. The support rod 121 and the support connection part 122 are fixedly installed by the cooperation of the second swivel fastener 102 at the other end of the support rod 121 and the first swivel fastener 101 at the other end of the connecting rod 1222. Both ends of the rotating shaft 1221 are welded with first swivel fasteners 101, which facilitates connection with other components, ensures good stress distribution, and makes the structure more stable.

[0070] It should be noted that there is no specific limitation on whether the first swivel coupler 101 or the second swivel coupler 102 of the scaffolding connecting coupler 100 is fixedly installed on each component. This article is only an example, and the specific use depends on the actual situation.

[0071] For example, both the support rod 121 and the support connection 122 are made of Q355 steel. The support rod 121, as a load-bearing component, can be used alone as a template support or as part of an arc-shaped support assembly system.

[0072] like Figure 7 and Figure 11 As shown, in some embodiments of the present invention, each first arc-shaped support assembly 140 and second arc-shaped support assembly 170 includes an arc-shaped component 141. A rotating platform 1411 is provided at the middle position of the arc-shaped component 141, and a rotating shaft 1221 is connected to the rotating platform 1411. Specifically, the two ends of the arc-shaped component 141 are extended by welding a first rotating fastener 101 or a second rotating fastener 102. The rotating shaft 1221 is embedded in the rotating platform 1411, so that it is configured as a rotatable structure to ensure the stability of the system support. At this time, the first rotating fasteners 101 welded to both ends of the rotating shaft 1221 are located on both sides of the arc-shaped component 141, which facilitates connection with the inclined support assembly 160.

[0073] Furthermore, both the first arc-shaped support assembly 140 and the second arc-shaped support assembly 170 also include an adjusting rod 142. The adjusting rod 142 is designed to adjust the distance between the various components, ensuring smooth connection. One end of the adjusting rod 142 is fixed to the middle of the arc-shaped component 141, and the other end is welded with, for example, a first swivel fastener 101, to securely connect with the second connecting assembly 150, ensuring the overall stability of the frame system. Exemplarily, both the arc-shaped component 141 and the adjusting rod 142 are made of Q355 steel.

[0074] like Figure 7 , Figure 11 and Figure 12 As shown, in some embodiments of the present invention, each inclined support assembly 160 includes a tie rod 161 and two connecting bolts 162. The two connecting bolts 162 are movably connected to both ends of the tie rod 161, and each connecting bolt 162 is connected to one end of the rotating shaft 1221 via a scaffolding connecting fastener 100. Specifically, by movably connecting two connecting bolts 162 to both ends of the tie rod 161, a rotatable structure is formed. Each connecting bolt 162 is welded with, for example, a second rotating fastener 102, so that the second rotating fastener 102 welded to the connecting bolt 162 also forms a rotatable structure. When the tie rod 161 is installed onto the arc-shaped component 141, the second rotating fastener 102 welded to the connecting bolt 162 and the first rotating fastener 101 welded to the rotating shaft 1221 are fitted together, thereby enabling the inclined support assembly 160 to be installed between the first arc-shaped support assembly 140 and the second arc-shaped support assembly 170, forming a geometrically invariant force-bearing system, ensuring good force distribution, and making the structure more stable. For example, the pull rod 161 is made of Q355 steel.

[0075] By using the connecting bolt 162, the first swivel fastener 101 or the second swivel fastener can be designed as a rotatable structure, so as to be flexibly controlled according to different usage scenarios and used as a flexible connection node.

[0076] like Figure 7 and Figure 13As shown, in some embodiments of the present invention, each top adjustment assembly 110 includes a top support plate 111, a screw 112, and a threaded sleeve 113. The top support plate 111 is connected to the top of the screw 112, and the bottom of the screw 112 is fitted into the threaded sleeve 113. Specifically, the screw 112 is threadedly fixed in the threaded sleeve 113, allowing the screw 112 to be suspended at any position and its height to be adjusted arbitrarily; the top support plate 111 is detachably connected to the top of the screw 112. Exemplarily, a second rotating fastener 102 is welded to the bottom of the threaded sleeve 113. The second rotating fastener 102 welded to the bottom of the threaded sleeve 113 cooperates with a first rotating fastener 101 welded to one end of the support rod 121 to achieve a fixed connection between the top adjustment assembly 110 and the first vertical support assembly 120, ensuring the stability of the frame system.

[0077] like Figure 7 and Figure 14 As shown, in some embodiments of the present invention, the hoisting support assembly 190 includes a keel support member 191, an adjusting screw 192, and a sleeve 193. The keel support member 191 slides freely on the adjusting screw 192, moving arbitrarily between them. Support is provided by the keel support member 191 sliding to the bottom. When the frame system is under tension, the scaffold connecting fastener 100 bears the tensile force, fulfilling the keel's support function. It serves as a hoisting structure and can also be used as a platform for laying operating platform treads. The adjusting screw 192 is threaded onto the sleeve 193, allowing it to withstand pressure on the ground and tension in the air, and its height can be adjusted arbitrarily. Exemplarily, a second rotating fastener 102 is welded to the top of the sleeve 193. This fastener, in conjunction with the first rotating fastener 101 welded to one end of the support rod 121 of the second vertical support assembly 180, achieves a fixed connection between the hoisting support assembly 190 and the second vertical support assembly 180, ensuring the stability of the frame system.

[0078] like Figure 7 and Figure 8 As shown, in some embodiments of the present invention, the first connecting component 130 and the second connecting component 150 are both composed of a steel pipe and a first swivel fastener 101 or a second swivel fastener 102 welded to both ends of the steel pipe. The two first vertical support components 120 are respectively installed at both ends of the steel pipe by the cooperating first swivel fastener 101 and the second swivel fastener 102; and the first arc-shaped support component 140 and the second arc-shaped support component 170 are installed at both ends of the steel pipe by the cooperating first swivel fastener 101 and the second swivel fastener 102, thereby forming a stable support system.

[0079] The combined support structure of the top adjustment component 110, the first vertical support component 120, the first arc-shaped support component 140, the second connecting component 150, the second arc-shaped support component 170, and the second vertical support component 180 provides a new approach to supporting independent beams and elevator shaft slabs. It can utilize the load-bearing capacity of existing structures to support independent beam structures and elevator shaft top beam and slab structures, avoiding the need to erect large-area, large-volume scaffolding. At the same time, the use of scaffolding connecting couplers 100 makes the connection between various components more convenient, avoiding the need to use various tools to assist in the erection. The top support structure can support the beam and slab structure, and the bottom support section can be connected to the hoisting support component 190 to place treads as a construction platform.

[0080] like Figure 1 , Figure 7 and Figure 11 As shown, in some embodiments of the present invention, the scaffolding connecting coupler 100 is also used in the column support system of the arched structure. A first swivel coupler 101 or a second swivel coupler 102 is welded to the bottom of the column support member and connected to the arc-shaped member 141, thereby transferring the load to the column support member. The first swivel coupler 101 or the second swivel coupler 102 provided at the top of the column support member is connected to the embedded part of the column, which can transfer the load to the column, preventing the embedded part from bearing shear force and ensuring the stability of the system.

[0081] It should be noted that the various inclined support components 160, the first vertical support component 120, the second vertical support component 180, the top adjustment component 110, the first connecting component 130, the second connecting component 150, the hoisting support component 190, the first arc-shaped support component 140, the second arc-shaped support component 170, and the column support components can be assembled in the manufacturing plant using the first swivel coupler 101 or the second swivel coupler 102. After assembly, they can be directly used for the erection of on-site construction scaffolding.

[0082] like Figure 7 and Figure 8 As shown, the scaffolding of this embodiment of the invention transfers the upper concrete load through the first vertical support component 120 to the first arc-shaped support component 140 and the second arc-shaped support component 170, and then through the first arc-shaped support component 140 and the second arc-shaped support component 170 to the column support member, and finally to the concrete column. This avoids the need to erect a large number of scaffolds to meet the height-to-width ratio, reduces material consumption, and improves construction efficiency.

[0083] It should be noted that the connection length of each component of the scaffolding can be designed according to specific needs, and this article does not make specific limitations on this.

[0084] In summary, to address the technical problems of increased construction difficulty and cost, and reduced construction efficiency during the erection, use, and dismantling of existing technologies, this invention provides a scaffolding connecting coupler and scaffolding. Through a design where a first protrusion and a second recess are adapted to each other, and the first recess and the second protrusion are adapted to each other, with positioning holes corresponding to positioning elements and multiple elastic limiting elements corresponding to multiple limiting holes, convenient assembly and disassembly of the first and second swivel couplers are achieved. Specifically, when assembling the first and second swivel couplers, the positioning elements are first inserted into the positioning holes... The second rotating fastener is positioned in the first rotating fastener, using this as a fixed center to facilitate rotation of the second rotating fastener relative to the first rotating fastener. At this time, each elastic limiting member is in an elastically compressed state. The second rotating fastener is then rotated until each elastic limiting member engages in its corresponding limiting hole. The elastic limiting member then returns to its natural extended state, preventing movement and thus ensuring a stable connection between the first and second rotating fasteners. When removing the first and second rotating fasteners, simply pressing down the elastic limiting member separates them, greatly simplifying the removal process, improving construction efficiency, and reducing construction costs. This invention provides good support for various slab and beam structures, is easy to assemble without the need for wrenches, hammers, or other tools, and has no easily lost components, ensuring good stability. It solves the support problems of independent beams and elevator shaft slabs, avoiding the need for multiple rows of scaffolding or laying I-beams due to excessive height-to-width ratios, which wastes materials and reduces construction efficiency. Construction is simple. One-time assembly eliminates the need for secondary construction, making the overall construction flow smoother and the process arrangement more rational. Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
