Description

Technical Field

[0001] This utility model relates to the field of building materials and structural engineering technology, and in particular to a galvanized steel pipe with a reinforced structure. Background Technology

[0002] Currently, galvanized steel pipes are widely used as a structural material in the construction and engineering fields, applied in various support and frame structures. However, in practical applications, due to the need for galvanized steel pipes to withstand significant external forces or complex stress distributions, their structural strength sometimes fails to meet the requirements of specific scenarios. For example, when erecting high-rise scaffolding or heavy equipment support frames, ordinary galvanized steel pipes are prone to deformation or even damage due to localized stress concentration, leading to safety hazards. To enhance the load-bearing capacity of steel pipes, additional reinforcements are typically added to the surface or thicker pipe walls are used, but this significantly increases the overall weight and material costs. Furthermore, existing strengthening methods often require complex processing techniques, increasing production cycles and construction difficulty, while also placing higher demands on the corrosion resistance and service life of the steel pipes. Therefore, how to ensure the strength of galvanized steel pipes while simultaneously achieving lightweight and economic efficiency has become an urgent technical problem to be solved. Utility Model Content

[0003] The purpose of this utility model is to provide a galvanized steel pipe with a reinforced structure, which solves the problems mentioned in the background art.

[0004] This invention is achieved by providing a galvanized steel pipe with a reinforced structure. This galvanized steel pipe significantly improves its resistance to deformation and load-bearing capacity by incorporating reinforcing ribs inside the pipe body and adding multi-segment elastic collars on the outside, while also achieving lightweight and economic benefits. The galvanized steel pipe mainly consists of a pipe body, reinforcing ribs inside the pipe body, and multi-segment elastic collars on the outside of the pipe body.

[0005] The tube body is a cylindrical hollow structure with multiple reinforcing ribs evenly distributed along its inner wall along the axial direction. The cross-section of each reinforcing rib is trapezoidal, with its bottom fixed to the inner wall of the tube and its top extending towards the center of the tube. The number of reinforcing ribs is determined based on the tube diameter and the application, typically ranging from 4 to 8, with each rib spaced evenly. The reinforcing ribs are made of the same galvanized steel as the tube body, and both are manufactured using a one-piece molding process to ensure connection strength and corrosion resistance. The design of the reinforcing ribs not only effectively disperses localized stress concentration under load but also increases the overall rigidity of the tube to a certain extent, thus preventing bending or collapse caused by external forces.

[0006] A multi-segment elastic collar is fitted onto the outside of the pipe body, and it is composed of multiple arc-shaped segments. Each arc-shaped segment has protrusions and grooves at both ends, and adjacent arc-shaped segments are tightly connected through the engagement of the protrusions and grooves. The inner surface of the arc-shaped segments has corrugated protrusions, the shape of which matches the curvature of the outer wall of the pipe body to ensure maximum contact area between the collar and the pipe body. The corrugated protrusions are made of highly elastic rubber, and their hardness is adjusted according to actual usage requirements, typically selected in the range of Shore hardness 60 to 80. This design allows the multi-segment elastic collar to produce uniform elastic deformation when subjected to external pressure, thereby absorbing some impact energy and further improving the compressive strength of the pipe body. In addition, the modular structure of the multi-segment elastic collar facilitates installation and disassembly, is suitable for pipe bodies of different lengths, and will not damage the galvanized layer on the pipe body surface.

[0007] The synergistic effect of the reinforcing ribs and the multi-segment elastic collar is the core technical feature of this invention. When the pipe body is subjected to external loads, the reinforcing ribs first disperse the stress axially and radially through their special trapezoidal structure, reducing local stress concentration. Simultaneously, the multi-segment elastic collar, through its corrugated protrusions and tight fit with the outer wall of the pipe, forms an elastic protective layer, further absorbing and buffering external impact forces. This dual reinforcement mechanism not only improves the overall strength of the pipe body but also effectively extends its service life. Furthermore, since the design of both the reinforcing ribs and the multi-segment elastic collar does not significantly increase the weight of the pipe body, this galvanized steel pipe maintains excellent lightweight characteristics while meeting high strength requirements.

[0008] The pipe body has flanges at both ends, which are fixed to the pipe ends with bolts. The outer edge of the flange has multiple evenly distributed bolt holes for connecting to other components. The inner side of the flange has a sealing ring groove, in which a rubber sealing ring is embedded to prevent external moisture or impurities from entering the pipe body. The flange design not only enhances the connection stability between the pipe body and other components but also improves the overall sealing performance, thereby further enhancing its corrosion resistance and service life.

[0009] This invention relates to a reinforced galvanized steel pipe, which solves the problem of deformation caused by localized stress concentration in existing galvanized steel pipes through a dual reinforcement design of the internal and external parts of the pipe body. The reinforcing ribs, with their trapezoidal structure, effectively disperse stress, while the multi-segment elastic collar provides additional compressive protection through its corrugated protrusions. This design not only significantly improves the load-bearing capacity and deformation resistance of the galvanized steel pipe but also achieves lightweight and economic benefits. Furthermore, the introduction of a flange further enhances the connection stability and sealing performance of the pipe body, enabling it to adapt to more complex operating environments. This invention has a simple structure, is easy to process and install, and can be widely used in construction scaffolding, heavy equipment support frames, and other fields requiring high-strength steel pipes, demonstrating high practical value and promising prospects for widespread application.

[0014] This utility model discloses a galvanized steel pipe with a reinforced structure, the specific implementation of which is described in conjunction with the appendix. Figure 1 To be continued Figure 3 A detailed description is provided below. This galvanized steel pipe mainly consists of a pipe body 1, reinforcing ribs 2 installed on the inner wall of the pipe body 1, multi-segment elastic collars 3 fitted onto the outer side of the pipe body 1, and flanges 8 located at both ends of the pipe body 1. The structure, connection relationships, and mutual cooperation of each component will be described in detail below, and its operating principle and process will be explained in conjunction with actual application scenarios.

[0015] like Figure 1As shown, the tube body 1 is a cylindrical hollow structure made of galvanized steel, which has good corrosion resistance. Multiple reinforcing ribs 2 are evenly distributed axially along the inner wall of the tube body 1. The number of reinforcing ribs 2 is determined by the diameter of the tube body 1 and the application scenario, typically ranging from 4 to 8. The spacing between each reinforcing rib 2 remains equal to ensure uniform stress distribution. The cross-section of the reinforcing rib 2 is trapezoidal, with its bottom fixedly connected to the inner wall of the tube body 1 and its top extending towards the center of the tube body 1. The reinforcing ribs 2 and the tube body 1 are manufactured using an integral molding process. This connection method avoids weak points that may be introduced by welding or other additional connection methods, thus ensuring the strength and stability of the overall structure. The top of the reinforcing rib 2 does not contact the central axis of the tube body 1, therefore, sufficient flow space is still maintained inside the tube body 1, making it suitable for scenarios requiring the transport of fluids or gases.

[0016] A multi-segment elastic collar 3 is fitted onto the outside of the tube body 1, and it is composed of multiple arc-shaped segments 4 spliced ​​together. For example... Figure 3 As shown, each arc segment 4 has a protrusion 5 and a groove 6 at both ends, and adjacent arc segments 4 are tightly connected by the cooperation of the protrusion 5 and the groove 6. This split design allows the multi-segment elastic collar 3 to adapt to pipes 1 of different lengths and facilitates installation and disassembly. The inner surface of the arc segment 4 is provided with corrugated protrusions 7, the shape of which matches the curvature of the outer wall of the pipe 1 to ensure maximum contact area between the collar 3 and the pipe 1. The corrugated protrusions 7 are made of highly elastic rubber, and their hardness can be adjusted according to actual usage requirements, typically selected in the range of Shore hardness from 60 to 80. The design of the corrugated protrusions 7 allows the multi-segment elastic collar 3 to produce uniform elastic deformation when subjected to external pressure, thereby absorbing some impact energy and further improving the compressive strength of the pipe 1. In addition, the distribution density and height of the corrugated protrusions 7 can be optimized according to specific usage scenarios to meet different load-bearing requirements.

[0017] The synergistic effect of the reinforcing ribs 2 and the multi-segment elastic collar 3 is the core technical feature of this utility model. When the pipe body 1 is subjected to external loads, the reinforcing ribs 2 first disperse the stress axially and radially through their special trapezoidal structure, reducing local stress concentration. At the same time, the multi-segment elastic collar 3, through its corrugated protrusions 7, closely adheres to the outer wall of the pipe body 1, forming an elastic protective layer that further absorbs and buffers external impact forces. This dual reinforcement mechanism not only improves the overall strength of the pipe body 1 but also effectively extends its service life. The design of neither the reinforcing ribs 2 nor the multi-segment elastic collar 3 significantly increases the weight of the pipe body 1; therefore, this galvanized steel pipe maintains good lightweight characteristics while meeting high strength requirements.

[0018] Flanges 8 are provided at both ends of the pipe body 1, and the flanges 8 are fixedly connected to the ends of the pipe body 1 by bolts. Multiple evenly distributed bolt holes 9 are provided on the outer edge of the flanges 8 for connection with other components. A sealing ring groove 10 is provided on the inner side of the flange 8, and a rubber sealing ring is embedded in the sealing ring groove 10 to prevent external moisture or impurities from entering the interior of the pipe body 1. The design of the flanges 8 enhances the connection stability of the pipe body 1 with other components, while improving the sealing performance of the overall structure, thereby further improving its corrosion resistance and service life.

[0019] In practical applications, the galvanized steel pipe of this invention can be widely used in construction scaffolding, heavy equipment support frames, and other fields requiring high-strength steel pipes. For example, in construction scaffolding applications, the galvanized steel pipe serves as the main load-bearing component. Its internal reinforcing ribs 2 effectively disperse stress concentration caused by construction loads, preventing the pipe body 1 from bending or collapsing. The multi-segment elastic collar 3 provides additional compressive protection when the scaffolding is subjected to external impacts or vibrations, ensuring the safety of the overall structure. The flange 8 design allows for quick connection of the galvanized steel pipe to other scaffolding components, while the embedded rubber sealing ring prevents rainwater or dust from entering the pipe body 1, thereby extending its service life.

[0020] In heavy equipment support systems, galvanized steel pipes are commonly used to support large machinery. Due to the significant weight of the equipment, the pipe body 1 is prone to deformation under prolonged stress. In this case, the reinforcing ribs 2, with their trapezoidal structure, disperse stress axially and radially, reducing localized stress concentration and thus improving the overall rigidity of the pipe body 1. The multi-segment elastic collar 3, with its corrugated protrusions 7 tightly fitting against the outer wall of the pipe body 1, forms an elastic protective layer, further absorbing and buffering external impacts and ensuring the stability of the support system under complex working conditions. Furthermore, the modular structure of the multi-segment elastic collar 3 facilitates installation and disassembly on-site, improving construction efficiency.

[0021] In summary, this utility model presents a reinforced galvanized steel pipe, which solves the problem of deformation caused by localized stress concentration in existing galvanized steel pipes through a dual reinforcement design of the pipe body 1, both internally and externally. The reinforcing ribs 2 effectively disperse stress through their trapezoidal structure, while the multi-segment elastic collar 3 provides additional compressive protection through its corrugated protrusions 7. This design not only significantly improves the load-bearing capacity and deformation resistance of the galvanized steel pipe but also achieves lightweight and economic benefits. Furthermore, the introduction of the flange 8 further enhances the connection stability and sealing performance of the pipe body 1, enabling it to adapt to more complex operating environments. This utility model has a simple structure, is easy to process and install, and can be widely used in construction scaffolding, heavy equipment support frames, and other fields requiring high-strength steel pipes, possessing high practical value and promising prospects for promotion.

[0022] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0023] During the erection of construction scaffolding, galvanized steel pipes are first installed as the main load-bearing components. The pipe body 1 is connected to the scaffolding components via flanges 8 at both ends. The bolt holes 9 on the flanges 8 are used to secure the pipes to the scaffolding components with bolts, ensuring a stable connection. Simultaneously, a rubber sealing ring is embedded in the sealing groove 10 inside the flange 8, effectively preventing rainwater or dust from entering the pipe body 1, thus avoiding corrosion problems caused by external impurities and extending the service life of the pipe body.

[0024] When the scaffolding bears construction loads, the reinforcing ribs 2 come into play. Because the cross-section of the reinforcing ribs 2 is trapezoidal, with the bottom fixed to the inner wall of the pipe 1 and the top extending towards the center of the pipe, this design allows the stress generated by external loads to be evenly distributed axially and radially. For example, in the application of high-rise scaffolding, when a section of galvanized steel pipe is subjected to a concentrated load, the reinforcing ribs 2, through their trapezoidal structure, transmit the stress from the point of application to the surrounding area, avoiding localized stress concentration and significantly reducing the risk of bending or collapse of the pipe 1.

[0025] Meanwhile, the multi-segment elastic collar 3 provides additional compressive protection on the outside. When the scaffolding experiences instantaneous loads due to external impacts or vibrations, the design of the corrugated protrusions 7 tightly fitting against the outer wall of the tube 1 plays a crucial role. The corrugated protrusions 7 are made of highly elastic rubber, and their hardness can be adjusted to a Shore hardness range of 60 to 80 according to actual needs. When external impact forces act on the tube 1, the corrugated protrusions 7 undergo elastic deformation, absorbing and buffering part of the impact energy, thereby further enhancing the compressive strength of the tube 1. In addition, the multi-segment elastic collar 3 is composed of multiple arc-shaped segments 4 spliced ​​together. Adjacent arc-shaped segments 4 are tightly connected through the cooperation of protrusions 5 and grooves 6. This split design not only facilitates installation and disassembly but also adapts to tubes 1 of different lengths, improving construction efficiency.

[0026] In heavy equipment support systems, galvanized steel pipes are used to support large mechanical equipment. Due to the significant weight of the equipment, the pipe body 1 is under high load for extended periods, making it prone to deformation due to stress concentration. In this case, the reinforcing ribs 2, with their unique trapezoidal structure, disperse the stress generated by the equipment's weight axially and radially, reducing the possibility of localized stress concentration and thus improving the overall rigidity of the pipe body 1. For example, when supporting a piece of mechanical equipment weighing several tons, the reinforcing ribs 2 can evenly distribute the equipment's weight across the entire inner wall of the pipe body 1, preventing any particular area from undergoing plastic deformation due to excessive pressure.

[0027] The multi-segment elastic collar 3 forms an elastic protective layer through the tight fit between its corrugated protrusions 7 and the outer wall of the tube body 1. When vibrations or external impacts occur during the operation of mechanical equipment, the corrugated protrusions 7 can absorb and buffer these dynamic loads, thereby ensuring the stability of the support frame under complex working conditions. In addition, the distribution density and height of the corrugated protrusions 7 can be optimized according to specific load-bearing requirements. For example, in scenarios requiring higher load-bearing capacity, the distribution density of the corrugated protrusions 7 can be increased or their height can be raised to enhance the compressive strength of the multi-segment elastic collar 3.

[0028] In summary, the galvanized steel pipe with reinforced structure of this utility model achieves its technical effects through the above steps. The reinforcing ribs 2, through their trapezoidal structure, disperse stress axially and radially, reducing local stress concentration and significantly improving the deformation resistance of the pipe body 1. The multi-segment elastic collar 3, through its corrugated protrusions 7 and tight fit with the outer wall of the pipe body 1, provides an elastic protective layer that absorbs and buffers external impact forces, further enhancing the compressive strength of the pipe body 1. The flange 8 design, through bolt connections and the setting of the sealing ring groove 10, enhances the connection stability of the pipe body 1 with other components and improves the sealing performance of the overall structure, thereby extending the service life of the galvanized steel pipe. The combination of the above steps and principles allows this utility model to meet high strength requirements while also considering lightweight and economy, possessing high practical value and promising prospects for promotion.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
