Description

Technical Field

[0001] The invention relates to the technical field of bridge construction, and in particular to a separated front support point guy rope hanging basket arc-shaped bow device and a construction method. Background Art

[0002] With the continuous development of modern bridge engineering, cable-stayed bridges, as an important form of bridge structure, are widely used in the construction of large-span bridges. During the construction of cable-stayed bridges, the hanging basket, as an important construction tool, plays a supporting role in the segmented construction of the main beam. Currently, in the construction of cable-stayed bridges, the design of the hanging basket usually relies on fixed fulcrums and rigging systems. However, due to the changes in the angle of the cable-stayed cable, especially when constructing different beam sections, the traditional hanging basket fulcrum is often unable to flexibly adapt to such changes, resulting in a mismatch between the anchoring position of the hanging basket fulcrum and the main beam during construction, thus affecting construction efficiency and safety.

[0003] Most existing cable-stayed bridge hanging basket design schemes fail to effectively consider the impact of the longitudinal and transverse angle changes of the cable-stayed cables on the configuration of the hanging basket fulcrum, resulting in insufficient adaptability of the hanging basket fulcrum, increasing uncertainty during the construction process, and may even lead to safety hazards such as fulcrum instability and hanging basket displacement. In addition, since the hanging basket fulcrum is mostly a fixed structure in traditional designs, it lacks flexibility and adjustment functions, resulting in the inability to achieve rapid and accurate adjustments according to the different needs of the beam section during the construction process, causing complexity and risks in construction operations. Summary of the invention

[0004] The purpose of the present invention is to provide a separated front support point cable hanging basket arc head device and a construction method to overcome the deficiencies in the prior art, thereby improving construction efficiency, simplifying the operation process, and ensuring construction safety.

[0020] S6. Fix the L-shaped clip and weld the L-shaped clip to both sides of the tension distribution beam to ensure that the arc head mechanism can slide up and down along the arc head under the action of the fall chain to avoid lateral sliding of the tension distribution beam due to the lateral component force.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figure 1-Figure 5 As shown, a separated front fulcrum cable hanging basket arc head device is characterized in that it includes a longitudinal beam mechanism 10, which is connected to a connecting cross beam 3; an arc head mechanism 11, including an upper arc head 4 of the longitudinal beam and a lower arc head 5 of the longitudinal beam, the upper arc head 4 of the longitudinal beam is connected to the longitudinal beam mechanism 10, and is used to connect the inclined cable and provide support, the lower arc head 5 of the longitudinal beam is connected to the longitudinal beam mechanism 10, and forms a fulcrum together with the upper arc head 4 of the longitudinal beam; a tensioning distribution beam 6 is arranged below the lower arc head 5 of the longitudinal beam, connected to the tensioning extension rod 8, and is used to ensure uniform distribution of force during the tensioning process.

[0035] The working principle of the device is based on the distribution of fulcrums and the uniform transmission of force. During the installation process, the longitudinal beam mechanism 10 and the connecting crossbeam 3 first form the basic structure of the device, and the longitudinal beam mechanism 10 is connected to other devices through the connecting crossbeam 3. The arc head mechanism 11 is composed of the arc head 4 on the longitudinal beam and the arc head 5 under the longitudinal beam. During installation, the arc head 4 on the longitudinal beam is responsible for connecting the inclined cable and plays a role of support and traction; while the arc head 5 under the longitudinal beam provides additional support and stability, becoming the fulcrum of the entire device. The arc head 4 on the longitudinal beam and the arc head 5 on the longitudinal beam cooperate with each other to jointly bear part of the force during the installation of the cable hanging basket. The tension distribution beam 6 is arranged below the arc head 5 under the longitudinal beam and is connected to the tension extension rod 8. During the tensioning process of the cable hanging basket system, the tension distribution beam 6 ensures the uniform distribution of force, prevents stress concentration caused by uneven tensioning, and thus improves the overall stability of the structure. The beneficial effects of the present invention are reflected in many aspects. First, the fulcrum structure formed by the arc-shaped head 4 on the longitudinal beam and the arc-shaped head 5 on the longitudinal beam effectively enhances the stability of the system, can withstand large external forces without being easily deformed, and improves the bearing capacity of the overall structure. Secondly, the tensioning distribution beam 6 ensures the uniform distribution of force during the tensioning process, avoids excessive local force caused by uneven tensioning, and thus improves the service life and safety of the equipment. In addition, the structural design of the present invention makes the device easier to install and adjust, reduces the complexity of construction, and saves manpower and time costs. Through these advantages, the device can achieve more efficient and stable tensioning operations in actual applications, and provide stronger protection during the construction process.

[0036] In the design of the longitudinal beam mechanism 10, materials of different materials or different cross-sectional shapes can be used to optimize the strength and rigidity of the structure, while reducing the weight and improving the economy and applicability of the overall device. In addition, the connection between the longitudinal beam upper arc head 4 and the longitudinal beam lower arc head 5 can be replaced by other forms of connection devices, such as bolts, welding or other mechanical connection methods, to adapt to different construction environments and requirements. The tension distribution beam 6 can also be designed as an adjustable structure, and its size or shape can be adjusted according to different tensioning forces and actual application requirements to achieve more accurate force distribution and control.

[0037] It also includes a cushion beam 7, which is arranged between the tension distribution beam 6 and the arc head mechanism 11. The design of the cushion beam 7 is added to further optimize the transmission and uniform distribution of force. During the tensioning process, the cushion beam 7 is arranged between the tension distribution beam 6 and the arc head mechanism 11 as an intermediate structure to play a role of buffering and balancing force. The cushion beam 7 can effectively reduce the local stress concentration caused by uneven tensioning force, thereby improving the stability and reliability of the entire structure. It cooperates with the tension distribution beam 6 and the arc head mechanism 11 to ensure that the structure can withstand greater external force during the tensioning process while maintaining uniform distribution of force. The existence of the cushion beam 7 makes the connection between the various components tighter and ensures the balance of the entire guying basket system. The present invention significantly enhances the overall stability of the device by arranging the cushion beam 7 between the tension distribution beam 6 and the arc head mechanism 11. The cushion beam 7 not only helps to evenly distribute the tensioning force and avoids uneven force transmission, but also effectively reduces the relative movement between the various components, thereby reducing the risk caused by equipment wear or excessive deformation. In addition, the design of the cushion beam 7 also improves the impact resistance of the entire system, allowing the guy wire hanging basket system to better cope with external impact and vibration in a complex construction environment and extend its service life. Through this improvement, the overall performance and safety of the device have been significantly improved.

[0038] In other embodiments of the present invention, the material and shape of the cushion beam 7 can be optimized according to the requirements of different construction environments. For example, a higher strength alloy material or composite material can be used to manufacture the cushion beam 7 to enhance its compression resistance and wear resistance. In addition, the design of the cushion beam 7 can also adjust its thickness, length or support position according to specific application requirements to adapt to cable hanging basket systems of different sizes and loads. In different construction environments, different installation methods can be selected, such as bolt fixing or welding connection, to ensure the stability of the cushion beam 7 and the reliability of long-term use. All of these changes can be made without deviating from the technical ideas of the present invention, thereby improving the applicability and flexibility of the device.

[0039] It also includes an L-shaped buckle 9, which is arranged on both sides of the tension distribution beam 6. The present invention further strengthens the connection and fixation of various parts of the device by arranging L-shaped buckles 9 on both sides of the tension distribution beam 6. The design of the L-shaped buckle 9 makes the connection between the tension distribution beam 6 and other structural parts more firm, preventing looseness or instability during the tensioning process. The L-shaped buckle 9 cooperates with both sides of the tension distribution beam 6, and through the locking effect of the buckle, the tension distribution beam and other key components (such as the arc head mechanism 11 and the cushion beam 7) are effectively fixed together, ensuring the stability of the device during use. The tensioning force is evenly transmitted to other parts of the structure through the L-shaped buckle 9, avoiding uneven force transmission caused by loose connection, thereby improving the safety and durability of the entire system. The present invention has significant beneficial effects by arranging L-shaped buckles 9 on both sides of the tension distribution beam 6. First, the L-shaped buckle 9 enhances the connection strength and stability between the components, prevents the loosening problem caused by excessive tension or external impact, and thus ensures the efficient operation of the entire cable hanging basket system. Secondly, the locking design of the L-shaped buckle 9 makes the installation and adjustment of each component more convenient, reduces the complexity of manual operation, and shortens the construction period. In addition, the application of the L-shaped buckle 9 also reduces the maintenance cost of the equipment because the buckle has a simple structure and is easy to inspect and replace. Through these advantages, the device shows higher reliability, economy and operability in practical applications.

[0040] In other embodiments, the material and shape of the L-shaped buckle 9 can be adjusted according to different usage environments. For example, stainless steel or galvanized materials with stronger corrosion resistance can be used to manufacture the L-shaped buckle 9 to adapt to long-term use in marine or high humidity environments. The size of the L-shaped buckle 9 can also be customized according to the size and load requirements of the specific tension distribution beam 6 to ensure the adaptability and functionality of the buckle. In addition, the installation method of the buckle can be welding, bolting, etc., which can be flexibly selected according to the needs of on-site construction. Through these optimizations, the present invention can provide more accurate and efficient solutions in different engineering projects, and further improve the adaptability and reliability of the device.

[0041] The upper end of the cushion beam 7 is arc-shaped and fits with the arc head 4 on the longitudinal beam and the arc head 5 under the longitudinal beam, and the lower end of the cushion beam 7 is flat and fits with the tension distribution beam 6. In the working principle of the present invention, the design of the cushion beam 7 provides better support stability through the fit of its upper end with the arc head 4 on the longitudinal beam and the arc head 5 under the longitudinal beam. The arc-shaped upper end is tightly matched with the arc head on the longitudinal beam, ensuring that the cushion beam 7 can be evenly transmitted to the longitudinal beam part when subjected to force, and the plane design of the lower end is tightly fitted with the tension distribution beam 6, so that the force can be evenly distributed to the tension distribution beam 6 and the arc head mechanism 11. This structural configuration of the cushion beam 7 enables the overall device to not only withstand greater tension during the tensioning process, but also maintain stable force transmission, avoiding deformation or damage caused by uneven force, thereby improving the safety and durability of the equipment. The present invention has significant beneficial effects through the fit between the arc-shaped upper end of the cushion beam 7 and the arc-shaped first portion 4 on the longitudinal beam and the arc-shaped first portion 5 on the longitudinal beam, as well as the fit between the lower end plane and the tension distribution beam 6. First, the arc-shaped design of the cushion beam 7 and the fit between the arc-shaped first portions 4 and 5 of the longitudinal beams make the force transmission more uniform, avoid local overload or stress concentration, and enhance the structural stability and safety of the device. Secondly, the plane design of the lower end of the cushion beam 7 and the tight fit with the tension distribution beam 6 ensure uniform force distribution during the entire tensioning process, thereby improving the working efficiency and stability of the device. Finally, this structural design enables the cushion beam 7 to not only effectively share the stress from tensioning, but also reduce the need for maintenance and replacement caused by material fatigue and deformation, thereby improving the durability and economy of the device.

[0042] In other embodiments of the present invention, the arc design of the upper end of the cushion beam 7 can be adjusted according to actual use needs to adapt to the different shapes of the upper arc head 4 of the longitudinal beam and the lower arc head 5 of the longitudinal beam. The curvature of the arc can be optimized according to the size of the tensioning force and the required mechanical properties to provide the best mechanical adaptability. In addition, the lower end plane of the cushion beam 7 can be designed with different angles or shapes according to the structural characteristics of the tension distribution beam 6 to ensure a more precise fit and achieve a better force distribution effect. The cushion beam 7 can also be made of a variety of materials, such as high-strength alloy steel, composite materials, etc., which can be selected according to different working environments and load requirements to ensure its stability and reliability in long-term use. Through the optimization of these designs, the cushion beam 7 can better adapt to the needs of various complex working conditions and provide more flexible and efficient solutions.

[0043] The L-shaped buckle 9 is welded on both sides of the tension distribution beam 6. In the present invention, the welding design of the L-shaped buckle 9 enhances the connection strength between the buckle and the tension distribution beam 6. By directly welding the L-shaped buckle 9 on both sides of the tension distribution beam 6, it is possible to effectively ensure the firm combination between the buckle and the beam body, and no loosening or falling off will occur during the tensioning process. The welding connection method is tighter than the traditional mechanical connection, and can better transmit the tension force and prevent uneven force transmission caused by loose connection. The welded L-shaped buckle 9 provides additional stability for the entire system and avoids the problem of loose connection caused by external force or long-term use, thereby ensuring the long-term reliability and safety of the device. The present invention significantly improves the overall stability and connection strength of the device by welding the L-shaped buckle 9 on both sides of the tension distribution beam 6. Compared with bolts or other mechanical connection methods, the welding method has higher shock resistance and durability, can maintain the stability of the connection during long-term use, and will not cause loose connection or failure due to vibration or external impact. This design improves the overall structural safety of the device and makes the force transmission between the tension distribution beam and other components more uniform and effective. Additionally, the welding process simplifies the installation process and reduces the need for additional tools and equipment, helping to reduce construction costs and time.

[0044] In other embodiments, the welding position and process of the L-shaped buckle 9 can be adjusted according to different design requirements. For example, the type of welding can be selected from conventional arc welding or high-strength laser welding, which is determined according to the properties of the material and the required welding strength. The specific method of welding can also adopt different processes such as spot welding or continuous welding to ensure that the connection between the buckle and the beam is more firm and uniform. In addition, the size, thickness and welding material of the L-shaped buckle 9 can also be appropriately adjusted according to the actual application to improve fatigue resistance and adapt to the use requirements under different environmental conditions. Through these adjustments, the device can better adapt to various construction environments and load requirements, and further improve the adaptability and performance of the device.

[0045] An elliptical hole is provided on the tensioning extension rod 8. In the present invention, the design of the elliptical hole provided on the tensioning extension rod 8 plays an important role, which is mainly reflected in improving the adjustment ability and adaptability during the tensioning process. The design of the elliptical hole can make the tensioning extension rod have a certain adjustment range during the installation process, avoiding the position offset or uneven force of the fixed point of the tensioning extension rod caused by installation error or uneven force. The shape of the elliptical hole can make the connection between the extension rod and other components more flexible, so that fine-tuning can be performed within a certain range to ensure the uniform distribution of the tensioning force. The size and position setting of the elliptical hole will be designed according to the specific load and tensioning requirements, so as to ensure that the tensioning extension rod can better adapt to the mechanical requirements when bearing the tensioning force, and improve the stability and safety of the overall device. The present invention has significant beneficial effects by providing an elliptical hole on the tensioning extension rod 8. First, the elliptical hole provides greater flexibility for the installation and adjustment of the tensioning extension rod, can effectively compensate for the installation error, and avoid the problem of uneven tensioning force caused by inaccurate hole position fixation. Secondly, the elliptical hole design can be fine-tuned as needed during the tensioning process, making the force distribution more uniform, effectively reducing the uneven force on the tensioning extension rod, reducing local stress concentration, and thus improving the stability and service life of the entire system. Finally, the elliptical hole design simplifies the installation and maintenance process of the equipment, saves adjustment time and cost, and further improves engineering efficiency.

[0046] In other embodiments of the present invention, the size and position of the elliptical hole on the tensioning extension rod 8 can be optimized according to specific application requirements. For example, the ratio of the major and minor axes of the elliptical hole can be adjusted according to the actual tensioning force to obtain the best adjustment space and mechanical adaptability. At the same time, the material of the elliptical hole can be selected with a more corrosion-resistant material to meet the use requirements under different environmental conditions, such as high humidity and high corrosion environments. The position of the elliptical hole can also be further optimized by changing the opening position of the hole to further optimize the adjustment range and force distribution of the tensioning extension rod. Through these adjustments, the embodiments of the present invention can flexibly adapt to various construction and use environments, and provide more stable and efficient tensioning operations.

[0047] like Figure 6 As shown, a construction method of a separated front fulcrum guy wire hanging basket arc-shaped head is also provided, using the separated front fulcrum guy wire hanging basket arc-shaped head device according to any one of claims 1 to 6, characterized in that the method comprises:

[0048] S1. Set a longitudinal beam mechanism 10, set two single longitudinal beams in the longitudinal direction of the bridge, and connect them through a connecting cross beam 3 to enhance the stiffness of the arc head and ensure that the arc head can adapt to the deformation of the inclined cable when the longitudinal and transverse angles change;

[0049] S2, install the arc head mechanism 11, connect the arc head 4 on the longitudinal beam with the arc head 5 under the longitudinal beam, the arc head 4 on the longitudinal beam is connected to the longitudinal beam mechanism 10, provides support for the inclined cable, and the arc head 5 under the longitudinal beam is connected to the longitudinal beam mechanism 10, and together form a fulcrum;

[0050] S3, setting a tension distribution beam 6, installing the tension distribution beam 6 below the lower arc head 5 of the longitudinal beam, setting an elliptical hole so that the tension extension rod 8 can pass through the elliptical hole, and ensuring uniform distribution of force during the tensioning process;

[0051] S4, adjusting the position of the connecting beam 3. If the extension rod 8 and the connecting beam 3 collide with each other during the tensioning process, the position of the connecting beam 3 is adjusted to avoid interference;

[0052] S5, install the arc-shaped cushion beam 7, and install the arc-shaped cushion beam 7 between the arc-shaped head mechanism 11 and the tension distribution beam 6, wherein the upper part of the cushion beam 7 is processed according to the curvature of the arc-shaped head, and the lower part is a plane, to ensure the fit between the tension distribution beam 6 and the cushion beam 7 to form a stable support;

[0053] S6. Fix the L-shaped buckle 9 and weld the L-shaped buckle 9 to both sides of the tension distribution beam 6 to ensure that the arc head mechanism 11 can slide up and down along the arc head under the action of the fall chain to avoid lateral sliding of the tension distribution beam 6 caused by the lateral component force.

[0054] The construction method ensures the smooth construction of the entire separated front fulcrum cable hanging basket arc head device by gradually installing and adjusting each component. First, step S1 enhances the rigidity of the arc head by setting the longitudinal beam mechanism 10 and the connecting crossbeam 3, ensuring that it can adapt to the deformation caused by the change of longitudinal and transverse angles when the inclined cable is tensioned. Then, step S2 connects the arc head on the longitudinal beam with the lower arc head to form a fulcrum, providing a solid foundation for the support of the inclined cable. Next, in step S3, the tension distribution beam 6 is installed and an elliptical hole is set to ensure the uniform distribution of force during the tensioning process. Step S4 avoids interference between the extension rod and the connecting crossbeam during the tensioning process by adjusting the position of the connecting crossbeam. In step S5, the installation of the arc pad beam ensures the fit and support between the tension distribution beam and the pad beam. Finally, step S6 avoids the lateral sliding of the tension distribution beam due to the lateral force component by welding the L-shaped buckle, ensuring the up and down sliding of the arc head under the action of the fall chain. The beneficial effect of this construction method is that the structural stability and mechanical properties of the entire guying basket arc head device are ensured through gradual installation and adjustment. Specifically, steps S1 and S2 ensure that the device is not easily deformed when subjected to tension by strengthening the rigidity of the longitudinal beam mechanism and the arc head; step S3 allows the tension to be more evenly distributed to the entire structure by setting an elliptical hole, avoiding deformation caused by uneven force; step S4 provides adjustment space to avoid interference between the extension rod and the connecting beam during construction; step S5 ensures a close fit between the cushion beam and the tension distribution beam, enhancing the supporting capacity of the device; step S6 solves the sliding problem caused by the lateral force component by welding an L-shaped buckle, thereby increasing the overall stability of the device. Therefore, this construction method not only improves the efficiency of construction, but also enhances the safety and durability of the device.

[0055] In other embodiments, the steps and technical solutions in the construction method can be flexibly adjusted according to different engineering requirements. For example, the setting of the longitudinal beam mechanism can be changed according to the span and structural requirements of the bridge, and different single longitudinal beams or multiple longitudinal beam structures can be used to adapt to different loads and construction conditions. The design of the elliptical hole can adjust the major and minor axis ratio of the hole according to the actual tension force requirements to optimize the force distribution. The welding method and position of the L-shaped buckle can also be adjusted according to the actual application to ensure the stability of the structure and the optimization of the welding strength. Through these adjustments, the construction method can better adapt to the engineering needs of different scales and environmental conditions, and improve the operability and accuracy of the construction.

[0056] In S3, a transverse beam and a stiffening plate are arranged on the tension distribution beam 6 to strengthen the rigidity of the tension distribution beam 6. In the construction method of the present invention, step S3 significantly improves the overall rigidity of the tension distribution beam by arranging a transverse beam and a stiffening plate on the tension distribution beam 6. The transverse beam increases the bending resistance of the beam body by connecting multiple support points laterally, and effectively prevents the bending or deformation of the beam body that may occur during the tensioning process. The stiffening plate reduces the deformation of the beam body during the tensioning process by strengthening the local rigidity of the beam body, and further improves the stability of the tension distribution beam when it is subjected to external tensioning force. This design ensures that the tension distribution beam 6 can distribute force more evenly during the entire tensioning process, avoiding deformation or degradation of mechanical properties caused by insufficient structural rigidity, thereby improving the working efficiency and service life of the entire device. The present invention has significant beneficial effects by arranging a transverse beam and a stiffening plate on the tension distribution beam 6. First, the diaphragm and stiffening plate effectively improve the bending stiffness of the tension distribution beam, ensuring that the beam body can maintain a small deformation during the tensioning process, avoiding uneven force distribution and system instability caused by excessive bending. Secondly, this enhanced stiffness design prevents the tension distribution beam from permanent deformation due to material fatigue or external impact during long-term use, thereby extending the service life of the equipment. In addition, due to the enhanced stiffness of the tension distribution beam, the force transmission becomes more uniform and stable, improving the efficiency of engineering construction and the safety of equipment.

[0057] When the tensioning extension rod 8 passes through the elliptical hole in S3, the position and size of the elliptical hole are adjusted to ensure that the extension rod 8 can pass smoothly. In step S3, the design of the tensioning extension rod 8 passing through the elliptical hole makes the tensioning process have higher flexibility and adjustment space. The shape and size of the elliptical hole allow the position of the butt rod 8 to be fine-tuned, thereby ensuring that the extension rod can pass through the hole smoothly and avoiding the blocking phenomenon caused by too small a hole diameter or improper position. During the tensioning process, by adjusting the position and size of the elliptical hole, the coordination between the extension rod and the hole can be adjusted in real time to ensure the smooth installation of the extension rod and the uniform distribution of the tensioning force. The adjustment of the elliptical hole can effectively avoid mechanical instability caused by installation errors or inaccurate hole positions, and ensure the overall safety and efficiency of the tensioning system. The present invention ensures that the tensioning extension rod 8 can pass smoothly by adjusting the position and size of the elliptical hole, effectively avoiding mechanical problems in the tensioning process caused by installation errors or design deviations. This adjustment method improves the flexibility during the construction process and reduces construction delays or repeated work caused by asymmetric hole positions or inappropriate extension rods. By adjusting the size of the elliptical hole, the passage of the extension rod can be accurately controlled under different conditions, thereby ensuring the mechanical properties and stability of the tension extension rod, ensuring the uniform distribution of force, and avoiding structural damage caused by uneven tension. This design not only simplifies the construction process, but also improves the construction efficiency and long-term reliability of the overall system.

[0058] In S5, high-strength bolts are used to connect the arc-shaped cushion beam 7 and the tension distribution beam 6. In step S5, the arc-shaped cushion beam 7 and the tension distribution beam 6 are connected by high-strength bolts, thereby ensuring a stable connection between the two. High-strength bolts have high tensile and shear strengths, and can effectively transmit and distribute forces during the tensioning process to prevent loosening or breaking of the connection parts. Bolt connection can provide higher mechanical properties and structural stability than traditional welding, especially under high load and frequent stress conditions, ensuring a close fit between the arc-shaped cushion beam and the tension distribution beam, thereby improving the rigidity and safety of the entire structural system. In addition, the high-strength bolt connection method makes installation during construction more convenient, and later maintenance and adjustment can be carried out, further improving the flexibility and operability of the construction process. The present invention has significant beneficial effects by using high-strength bolts to connect the arc-shaped cushion beam 7 and the tension distribution beam 6. First, the high-strength bolt connection not only improves the connection strength, but also enhances the durability of the structure, so that the arc-shaped cushion beam and the tension distribution beam can withstand greater forces during long-term use. Secondly, compared with welding, high-strength bolt connection is easier to construct and maintain later, reducing quality problems that may be caused by improper welding process, and can be easily adjusted or replaced, reducing the difficulty of maintenance. Finally, this design effectively improves the seismic resistance and stability of the entire structure, ensuring safety under dynamic loads. Through this high-strength bolt connection method, the connection between the arc cushion beam and the tension distribution beam is more firm and reliable, thereby improving the working efficiency and service life of the entire system.
