Description

Technical Field

[0001] This utility model relates to the technical field of scaffolding and wall connection components, and in particular to a wall connection component for scaffolding and a scaffolding fixing structure. Background Technology

[0002] Wall ties are crucial connecting components between scaffolding and the main building structure. Their core function is to effectively transfer lateral loads (such as wind loads and construction loads) from the scaffolding to the building structure, preventing overturning, slippage, or deformation. They are vital connectors for ensuring the overall stability of the scaffolding and construction safety. Traditional wall ties mainly employ rigid steel pipe ties with couplers, flexible steel wire rope ties, and steel-anchored wall ties. These ties restrict the lateral displacement of the scaffolding uprights, maintaining the stability of the scaffold structure.

[0003] Currently, existing scaffolding wall ties have the following technical problems: 1. Limited adaptability: Some wall ties cannot be flexibly adjusted according to the distance between the scaffolding and the building wall during actual use, and can only be used in a single application scenario, resulting in the inability to adjust the expansion distance of the wall ties according to changes in working conditions. 2. Poor connection reliability: In steel structures, irregular concrete structures (such as curved walls, cantilever structures), or narrow spaces, conventional wall ties are difficult to fix (e.g., the position of embedded parts is limited, and steel pipes cannot be aligned), requiring temporary modification of the wall ties, reducing connection reliability. 3. High construction costs: Some wall ties (such as embedded steel pipes and expansion bolts) are for single use and cannot be reused after dismantling, resulting in material waste and increased construction costs. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the technical problem to be solved by this utility model is to provide a wall connector for scaffolding and a scaffolding fixing structure, so as to solve the problems of limited adaptability to working conditions, poor connection reliability and high construction cost of the existing scaffolding fixing structure.

[0005] To solve the above-mentioned technical problems, this utility model provides a wall connector for scaffolding, used to connect scaffolding vertical poles and wall uprights respectively, comprising:

[0006] A telescopic assembly, wherein fastening components are respectively connected to both ends of the telescopic assembly;

[0007] The fastening assembly includes a first annular rotating member and a second annular rotating member. One end of the first annular rotating member is rotatably disposed at one end of the second annular rotating member. The other end of the first annular rotating member is detachably connected to the other end of the second annular rotating member. The second annular rotating member rotates along one end and switches between an open position and a locked position.

[0008] In the locked position, the other end of the first annular rotating member is connected to the other end of the second annular rotating member, and the inner ring surfaces of the first and second annular rotating members together form a limiting hole that is adapted to the scaffolding vertical pole and the wall upright pole; in the open position, the other end of the first annular rotating member opens to connect with the other end of the second annular rotating member, so as to satisfy the insertion or removal of the scaffolding vertical pole and the wall upright pole.

[0009] As a more preferred embodiment, the telescopic assembly includes a sleeve, inside which a first screw and a second screw are respectively disposed, and the first screw and the second screw are threadedly connected to the sleeve. Because of the threaded drive, the distance the screw moves (i.e., the pitch) per revolution is fixed; therefore, by controlling the rotation angle, the telescopic length can be accurately controlled, making it suitable for applications with high requirements for connection spacing. Furthermore, the threaded connection has high mechanical strength and can withstand large tensile and compressive loads; the first screw and the second screw are symmetrically stressed, achieving balanced force distribution, resulting in strong structural stability and reducing the likelihood of skewing or deformation, thus improving the overall structural stability.

[0010] As a more preferred embodiment, the inner ring of the sleeve is provided with internal threads, and the outer rings of the first and second screws are provided with external threads. The first and second screws are threadedly connected within the sleeve, resulting in a small external dimension; no additional guiding devices or complex transmission mechanisms are required, leading to a more compact structure; suitable for use in space-constrained construction sites or temporary support structures. Furthermore, due to the large mating surface between the sleeve and the screws, the force is evenly distributed, effectively transmitting larger loads, providing sufficient strength and stability, and reducing structural instability caused by inaccurate connector dimensions.

[0011] As a preferred embodiment, the threads of the first and second screws are in opposite directions, and the internal thread of the sleeve matches the external threads of the first and second screws, respectively. The first and second screws are designed with opposite thread directions (one left-handed and one right-handed); when the sleeve is rotated, both screws move inward or outward simultaneously, ensuring uniform force and structural symmetry throughout the telescopic assembly during expansion and contraction. This reduces the likelihood of deformation, jamming, or loosening due to excessive force on one side; and provides a more balanced and stable connection force when supporting scaffolding vertical poles and wall uprights. Furthermore, because both screws move simultaneously, users only need to apply a small rotational force to achieve a large range of telescopic adjustments; compared to single-sided adjustments or structures requiring separate operation, this design is more labor-saving and smoother, reducing the workload of construction workers and improving work efficiency.

[0012] As a preferred approach, the central axes of the first and second screws coincide. Because the center lines of the two screws coincide, their forces are completely aligned during extension and contraction; there is no eccentric force, torsion, or lateral force, thus preventing deformation, jamming, or loosening of the connectors. When bearing the weight of scaffolding verticals and wall uprights, it provides more stable and balanced support, improving overall safety. Furthermore, since the two screws move on the same axis, no additional lateral friction is generated; the contact friction and wear between the threads are reduced, helping to lower maintenance frequency, reduce maintenance costs, and extend the service life of the mechanism. Moreover, the coaxial design allows the two screws to be closely aligned, eliminating the need for additional offset space, facilitating installation and operation in confined spaces, and making it suitable for construction environments with high space requirements, such as building sites.

[0013] As a more preferred approach, both ends of the first and second annular rotating components are provided with through holes. By providing through holes at both ends of the annular components of the first and second annular rotating components, the two ends can be connected using connectors such as pins and bolts; one end can be rotatably connected (e.g., by inserting a pin), allowing the annular component to rotate freely around the axis, achieving an "opening and closing" function, facilitating the insertion or removal of scaffolding vertical poles and wall uprights; the other end can be detachably connected (e.g., by inserting bolts or quick-release pins), achieving flexible switching between locking and unlocking; the through hole design facilitates the disassembly and assembly of fastening components, improving operational convenience.

[0014] As a more preferred embodiment, the fastening assembly further includes a first connector and a second connector. The first connector passes through a through hole at one end of the first and second annular rotating parts, rotatably positioning one end of the first annular rotating part at one end of the second annular rotating part. The second connector passes through a through hole at the other end of the first and second annular rotating parts, allowing the other end of the first and second annular rotating parts to be detachably connected. This "one end fixed and rotating, one end detachable" structural design—one end for rotation (flexibility), one end for locking (stability)—allows the entire fastening assembly to open and close easily while also locking securely, meeting the dual requirements of convenient installation and stable support for scaffolding connectors. In addition, the first connector acts as a "rotation axis" to ensure that the ring-shaped part moves smoothly and does not wobble during opening and closing; the second connector acts as a "locking device" to effectively transmit tensile, compressive and shear forces in the locked state to ensure a firm connection; the clear division of labor between the two ends makes the entire fastening assembly more evenly stressed and structurally stable when under load, avoiding deformation or loosening, and helping to enhance the safety and reliability of the connector under heavy loads and other environments.

[0015] As a more preferred embodiment, the first annular rotating component includes a first annular block and a first enclosing column, with the inner annular wall of the first annular rotating component and the outer annular wall of the first enclosing column being fitted and fixed together; the second annular rotating component includes a second annular block and a second enclosing column, with the inner annular wall of the second annular rotating component and the outer annular wall of the second enclosing column being fitted and fixed together. The design of the enclosing column enhances the strength of the annular rotating component in areas of concentrated stress, improves the structure's resistance to bending and shearing, and prevents local deformation or cracking of the annular block due to long-term stress. This structural design significantly improves the durability and reliability of the fastening components, reducing the frequency of maintenance and replacement. Furthermore, the fitted fixing method (such as welding, riveting, bolting, or adhesive) between the annular block and the enclosing column further ensures the positional accuracy and connection strength between them, improving the overall stability of the structure.

[0016] As a preferred embodiment, the first and second enclosing columns are semi-annular columns, forming a limiting hole that fits the wall column. The semi-annular column design allows the two columns to naturally form a complete cylindrical cavity when closed. This cavity precisely matches the outer diameter of the wall column, achieving a tight fit. Compared to polygonal or other irregularly shaped cylindrical fits, this provides better contact area and uniform force distribution, effectively preventing loosening, slippage, or deformation, and improving overall connection stability. Furthermore, because the enclosing columns are semi-annular, when the annular rotating component is in the open / closed position, the two semi-annular columns naturally separate, forming an open entrance, facilitating the insertion or removal of the wall column from the side without complex operations. During locking, simply rotating the annular component closes the two semi-annular columns, quickly completing the clamping process. This simple operation helps save time and reduce material costs.

[0017] As a more preferred method, the first type of scaffolding fixing structure includes: scaffolding and a wall, wherein scaffolding vertical poles are provided on the scaffolding and wall columns are provided on the wall.

[0018] As described above, the wall connector and scaffold fixing structure for scaffolding involved in this utility model have the following beneficial effects: When in use, the wall connector for scaffolding of this utility model adopts a design of "rotatable connection at one end and detachable connection at the other end", which allows the annular rotating part to quickly switch between "locked position" and "open position"; during installation, simply open the first annular rotating part and the second annular rotating part, insert the scaffolding vertical pole and the wall upright, and then close them to achieve locking; disassembly is done in reverse, without complicated tools or steps, making operation simple, installation and disassembly convenient, which can significantly improve work efficiency and reduce labor costs and construction time.

[0019] The telescopic component of this invention can be length-adjusted according to the actual distance between the scaffolding vertical pole and the wall upright; it eliminates the need to design multiple specifications of connectors for different installation environments, making it versatile and adaptable; it is suitable for various building structures and construction scenarios, improving the versatility of the structure and meeting diverse construction needs.

[0020] The fastening assembly of this utility model is composed of two annular rotating parts connected by a connector. It has a simple structure and reasonable design. Each component can be processed separately and produced in a standardized manner, reducing manufacturing difficulty and cost. If a component is damaged, it can be replaced individually without replacing the entire structure, which facilitates installation and maintenance and extends the service life of the product.

[0021] This utility model's scaffolding fixing structure utilizes the aforementioned wall connectors for scaffolding to achieve a stable connection between the scaffolding and the building wall. The wall connectors connect the scaffolding vertical poles to the wall columns, transforming the scaffolding from an independent support into a stable tie or support relationship with the building. This helps improve the overall stability of the scaffolding and prevents it from tilting, swaying, or collapsing due to external forces (such as wind loads or construction loads). Furthermore, the wall connectors are adjustable in length and quick to assemble and disassemble, allowing the fixing structure to adapt to the connection needs of building walls with varying spacing, improving construction flexibility and efficiency, and reducing construction costs. This solves the problems of existing scaffolding fixing structures, such as limited adaptability to different working conditions, poor connection reliability, and high construction costs.

It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit the utility model.

[0047] like Figures 1 to 4 As shown, this utility model provides a wall connector for scaffolding, used to connect scaffolding vertical poles and wall uprights respectively, including:

[0048] Telescopic component 1, with fastening components 2 connected to both ends of the telescopic component 1;

[0049] The fastening assembly 2 includes a first annular rotating member 21 and a second annular rotating member 22. One end of the first annular rotating member 21 is rotatably disposed at one end of the second annular rotating member 22. The other end of the first annular rotating member 21 is detachably connected to the other end of the second annular rotating member 22. The second annular rotating member 22 rotates along one end and switches between an open position and a locked position.

[0050] In the locked position, the other end of the first annular rotating member 21 is connected to the other end of the second annular rotating member 22, and the inner ring surfaces of the first annular rotating member 21 and the second annular rotating member 22 together form a limiting hole that is adapted to the scaffolding vertical pole 3 and the wall upright pole 4; in the open position, the other end of the first annular rotating member 21 is opened to connect with the other end of the second annular rotating member 22, so as to satisfy the insertion or removal of the scaffolding vertical pole 3 and the wall upright pole 4.

[0051] In some embodiments of this utility model, such as Figure 1 As shown, the telescopic assembly 1 includes a sleeve 12, inside which a first screw 11 and a second screw 13 are respectively disposed, and the first screw 11 and the second screw 13 are threadedly connected to the sleeve 12. Because of the threaded drive, the distance the screw moves (i.e., the pitch) per revolution is fixed; therefore, by controlling the rotation angle, the telescopic length can be accurately controlled, making it suitable for applications with high requirements for connection spacing. Furthermore, the threaded connection has high mechanical strength and can withstand large tensile and compressive loads; the first screw 11 and the second screw 13 are symmetrically stressed, achieving balanced force distribution, strong structural stability, and are not prone to skewing or deformation, thus improving the overall structural stability.

[0052] In some embodiments of this utility model, such as Figure 1 As shown, the inner ring of the sleeve 12 is provided with internal threads, and the outer rings of the first screw 11 and the second screw 13 are provided with external threads. The first screw 11 and the second screw 13 are threadedly connected within the sleeve 12, resulting in a small external dimension; no additional guiding device or complex transmission mechanism is required, making the structure more compact; suitable for use in space-constrained construction sites or temporary support structures. Furthermore, due to the large mating surface between the sleeve 12 and the screws, the force is evenly distributed, effectively transmitting larger loads, providing sufficient strength and stability, and reducing structural instability problems caused by inaccurate connector dimensions.

[0053] In some embodiments of this utility model, such as Figure 1As shown, the threads of the first screw 11 and the second screw 13 have opposite directions of rotation, and the internal thread of the sleeve 12 matches the external threads of the first screw 11 and the second screw 13, respectively. The first screw 11 and the second screw 13 are designed with threads in opposite directions (i.e., one is left-handed and the other is right-handed); when the sleeve 12 is rotated, the two screws will move inward or outward simultaneously, so that the entire telescopic assembly 1 is subjected to uniform force and has a symmetrical structure during the telescopic process; it is not easy to have problems such as deformation, jamming or loosening caused by excessive force on one side; when bearing the scaffolding vertical pole 3 and the wall upright, it can provide a more balanced and stable connection force. Furthermore, since the two screws move simultaneously, the user only needs to apply a small rotational force to achieve a large range of telescopic adjustment; compared with the structure of single-sided adjustment or the need for separate operation, this design is more labor-saving and smoother, which can reduce the operating intensity of construction personnel and improve work efficiency.

[0054] In some embodiments of this utility model, such as Figures 1 to 4 As shown, the central axes of the first screw 11 and the second screw 13 coincide. Because the center lines of the two screws coincide, their forces are completely aligned during extension and contraction; there will be no eccentric force, torsion, or lateral force, thus preventing deformation, jamming, or loosening of the connectors. When bearing the weight of the scaffolding vertical poles 3 and the wall uprights 4, it provides a more stable and balanced support force, improving overall safety. Furthermore, since the two screws move on the same axis, no additional lateral friction is generated; the contact friction and wear between the threads are reduced, helping to lower maintenance frequency, reduce maintenance costs, and extend the service life of the mechanism. Moreover, the coaxial design allows the two screws to be closely arranged, eliminating the need for additional offset space, facilitating installation and operation in confined spaces, making it suitable for construction environments with high space requirements, such as building sites.

[0055] In some embodiments of this utility model, such as Figure 1 As shown, both ends of the first annular rotating member 21 and the second annular rotating member 22 are provided with through holes. By providing through holes at both ends of the annular members of the first and second annular rotating members 21 and 22, the two ends can be connected using connectors such as pins and bolts; one end can be rotatably connected (e.g., by inserting a pin), allowing the annular member to rotate freely around its axis, achieving an "opening and closing" function, facilitating the insertion or removal of the scaffolding vertical pole 3 and the wall upright pole 4; the other end can be detachably connected (e.g., by inserting a bolt or quick-release pin), enabling flexible switching between locking and unlocking; the through hole design facilitates the assembly and disassembly of the fastening components 2, improving operational convenience.

[0056] In some embodiments of this utility model, such as Figures 1 to 2As shown, the fastening assembly 2 further includes a first connector 212 and a second connector 223. The first connector 212 passes through the through holes at one end of the first annular rotating member 21 and the second annular rotating member 22, rotatably positioning one end of the first annular rotating member 21 at one end of the second annular rotating member 22. The second connector 223 passes through the through holes at the other end of the first annular rotating member 21 and the second annular rotating member 22, allowing the other end of the first annular rotating member 21 to be detachably connected to the other end of the second annular rotating member 22. Through this structural design of "one end fixed and rotating, one end detachable," i.e., one end for rotation (flexibility) and the other end for locking (stability), the entire fastening assembly 2 can be easily opened and closed, and also securely locked, meeting the dual requirements of convenient installation and stable support for scaffolding connectors. Furthermore, the first connector 212 acts as a "rotation axis," ensuring smooth and stable movement of the annular component during opening and closing; the second connector 223 acts as a "locking device," effectively transmitting tensile, compressive, and shear forces in the locked state to ensure a secure connection. The clear division of labor between the two ends makes the entire fastening assembly 2 more evenly stressed and structurally stable under load, preventing deformation or loosening, and enhancing the safety and reliability of the connector under heavy loads and other environmental conditions. For example, the first connector 212 passes through the through-holes at one end of the first annular rotating component 21 and the second annular rotating component 22; one end of the first annular rotating component 21 is rotatably connected to one end of the second annular rotating component 22; achieving the function of "one end rotatable," allowing the annular component to open and close freely around the connection point. The second connector 223 (such as a pin or bolt) is passed through the through holes at the other ends of the first annular rotating member 21 and the second annular rotating member 22, so that the other end of the first annular rotating member 21 and the other end of the second annular rotating member 22 are detachably connected; by inserting / pulling out the second connector 223, the "locked state" and "open state" can be switched.

[0057] In some embodiments of this utility model, such as Figure 2As shown, the first annular rotating component 21 includes a first annular block 211 and a first enclosing column 213, with the inner annular wall of the first annular rotating component 21 fitted and fixed to the outer annular wall of the first enclosing column 213; the second annular rotating component 22 includes a second annular block 221 and a second enclosing column 222; the inner annular wall of the second annular rotating component 22 is fitted and fixed to the outer annular wall of the second enclosing column 222. The design of the enclosing column can enhance the strength of the annular rotating component in areas of concentrated stress. For example, setting the enclosing column at the position in contact with the screw, pin, or connector can improve the bending and shear resistance; avoid local deformation or cracking of the annular block due to long-term stress; this structural design can significantly improve the durability and reliability of the fastening assembly 2 and reduce the frequency of maintenance and replacement. In addition, the method of fitting and fixing the annular block and the enclosing column (such as welding, riveting, bolting, or gluing) can further ensure the positional accuracy and connection strength between the two, and improve the overall stability of the structure.

[0058] In some embodiments of this utility model, such as Figure 2 and Figure 4 As shown, the first enclosing column 213 and the second enclosing column 222 are semi-annular columns, forming a limiting hole that matches the wall column 4. The semi-annular column design allows the two enclosing columns to naturally form a complete cylindrical inner cavity when closed. This inner cavity precisely matches the outer diameter of the wall column 4, achieving a tight fit. Compared to polygonal or other irregularly shaped cylindrical fits, this provides better contact area and uniform force distribution, effectively preventing loosening, slippage, or deformation, and improving overall connection stability. Furthermore, because the enclosing columns are semi-annular, when the annular rotating component is in the open / closed position, the two semi-annular columns naturally separate, forming an open entrance, facilitating the insertion or removal of the wall column 4 from the side without complex operations. During locking, simply rotating the annular component closes the two semi-annular columns, quickly completing the clamping process. This simple operation helps save time and reduce material costs.

[0059] In some embodiments of this utility model, such as Figure 4 As shown, the first type of scaffolding fixing structure includes: scaffolding and wall, with scaffolding vertical poles 3 installed on the scaffolding and wall columns 4 installed on the wall.

[0060] To better illustrate the wall connector and scaffold fixing structure of this utility model, the following specific application will be used as an example: When using the wall connector for scaffolding, the fastening component 2 adopts a design of "rotatable connection at one end and detachable connection at the other end," allowing the annular rotating component to quickly switch between a "locked position" and an "open / closed position." During installation, simply open the first annular rotating component 21 and the second annular rotating component 22, insert the scaffold vertical pole 3 and the wall upright 4, and then close them to achieve locking. Disassembly is performed in reverse, requiring no complex tools or steps. The operation is simple, and installation and disassembly are convenient, significantly improving work efficiency and reducing labor costs and construction time.

[0061] The telescopic component 1 of this utility model can adjust its length according to the actual distance between the scaffold vertical pole 3 and the wall upright pole 4; it eliminates the need to design multiple specifications of connectors for different installation environments, making it versatile and adaptable; it is suitable for various building structures and construction scenarios, improving the versatility of the structure and meeting diverse construction needs.

[0062] The fastening component 2 of this utility model is composed of two annular rotating parts connected by a connector. It has a simple structure and reasonable design. Each component can be processed separately and produced in a standardized manner, reducing manufacturing difficulty and cost. If a component is damaged, it can be replaced individually without replacing the entire structure, which facilitates installation and maintenance and extends the service life of the product.

[0063] This utility model's scaffolding fixing structure utilizes the aforementioned wall connectors for scaffolding to achieve a stable connection between the scaffolding and the building wall. The wall connectors connect the scaffolding vertical poles 3 to the wall columns 4, transforming the scaffolding from an independent support into a stable tie or support relationship with the building. This helps improve the overall stability of the scaffolding and prevents it from tilting, swaying, or collapsing due to external forces (such as wind loads or construction loads). Furthermore, the wall connectors are adjustable in length and quick to assemble and disassemble, allowing the fixing structure to adapt to the connection needs of building walls and scaffolding at different spacings, improving construction flexibility and efficiency, and reducing construction costs. This solves the problems of existing scaffolding fixing structures, such as limited adaptability to various working conditions, poor connection reliability, and high construction costs.

[0064] In summary, the wall connector and scaffold fixing structure of this utility model have the following advantages:

[0065] 1. Simple operation and easy installation:

[0066] Fastening component 2 adopts a design of "rotatable connection at one end and detachable connection at the other end", which can quickly switch between "locked position" and "open position". During installation, the rod is inserted and closed to lock. Disassembly is done by reversing the operation. No complicated tools are required, making it simple to operate, install and use.

[0067] 2. Adaptable to different construction needs:

[0068] The telescopic component 1 can flexibly adjust its length according to the actual distance between the scaffold vertical pole 3 and the wall upright pole 4. It does not require various specifications of connectors, has strong adaptability, and can meet diverse construction needs.

[0069] 3. Low cost and long service life:

[0070] Fastening assembly 2 consists of two annular rotating parts connected by a connector. It has a simple structure and reasonable design, which can reduce manufacturing difficulty and cost. Furthermore, the parts can be replaced individually when damaged, which facilitates installation and maintenance and extends the product's service life.

[0071] In summary, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.
