Description

Technical Field

[0001] This utility model belongs to the technical field of spiral steel pipes, specifically relating to a spiral steel pipe with a reinforcing rib structure. Background Technology

[0002] Spiral steel pipe is a type of steel pipe made by rolling and welding steel strips or plates into a spiral shape. During its manufacturing process, the steel strip is wound at a specific spiral angle, and then the joints are firmly connected through welding to form a continuous pipe body. Spiral steel pipes have a wide diameter range, and the production process can be adjusted according to engineering needs to produce pipes of different specifications. Spiral steel pipes with reinforced ribs are an enhanced type of steel pipe, based on traditional spiral steel pipes, with reinforced ribs added to the outside of the pipe body through a special process. This design significantly improves the overall rigidity and compressive strength of the steel pipe by forming raised rib structures on the pipe wall, making it less prone to deformation or breakage when subjected to higher pressure or complex loads.

[0003] However, existing spiral steel pipes with reinforced ribs have limited support strength due to their simple structure. When subjected to a large impact, they may still deform, affecting their use. Utility Model Content

[0004] The purpose of this utility model is to provide a spiral steel pipe with a reinforcing rib structure to solve the problem mentioned in the background art that the existing spiral steel pipes with reinforcing rib structures have limited supporting strength due to their simple structure, and may still deform under large impacts, thus affecting the use of the spiral steel pipes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spiral steel pipe with a reinforcing rib structure, comprising a spiral steel pipe and reinforcing ribs spirally arranged on the outer side of the spiral steel pipe; The spiral steel pipe is provided with multiple fixing screws on the outside and multiple fixing welding plates on the inner wall of the spiral steel pipe. The spiral steel pipe is provided with an inner sleeve layer. Multiple annular welding plates are provided on the outside of the inner sleeve layer. Connecting welding plates are arranged transversely between the annular welding plates. Multiple fixing screw holes are provided on the connecting welding plates. Shock-absorbing filler is provided in the gap between the annular welding plates and the connecting welding plates.

[0006] Preferably, the fixing welding plate is welded to the spiral steel pipe, and the fixing welding plate is a long strip-shaped metal block. The fixing welding plate can provide initial support to the spiral steel pipe from the inner wall of the spiral steel pipe.

[0007] Preferably, the annular welding plate is welded to the inner sleeve layer, and the annular welding plate can strengthen the outer layer of the inner sleeve layer. The connecting welding plate is laterally connected to the annular welding plate, and the connecting welding plate is welded to both the annular welding plate and the inner sleeve layer.

[0008] Preferably, the cross-mesh structure formed by the annular welding plate and the connecting welding plate can not only strengthen the exterior of the inner sleeve layer, but also provide support for the inner wall of the spiral steel pipe.

[0009] Preferably, the shock-absorbing filler is adhered and fixed in the gap formed between the annular welding plate and the connecting welding plate. The shock-absorbing filler is made of rock wool. The shock-absorbing filler can not only reduce the vibration of the inner sleeve layer, but also play a certain role in sound insulation of the inner sleeve layer.

[0010] Preferably, a groove is provided between the annular welding plate and the connecting welding plate, the inner sleeve can be connected to the fixed welding plate through the groove, and the inner sleeve can be fixedly installed to the spiral steel pipe through fixing screws and fixing screw holes.

[0011] Preferably, the spiral steel pipe is provided with connecting flanges at both ends, and the connecting flanges at both ends are provided with mating bolts and mating bolt holes, and the spiral steel pipe is fixedly connected by the connecting flanges, mating bolts and mating bolt holes.

[0012] Compared with the prior art, this utility model provides a spiral steel pipe with a reinforcing rib structure, which has the following beneficial effects: 1. By setting up an inner sleeve, annular welding plate, connecting welding plate, fixing screws, fixing screw holes, and fixing welding plate, the structural strength of the spiral steel pipe is significantly improved. The fixing welding plate is welded to the inner side of the pipe wall to form a stable basic support, while the grid structure constructed by the cross welding process of the annular welding plate and connecting welding plate effectively enhances the rigidity of the outer side of the inner sleeve. Combined with the precision locking mechanism of the fixing screws and screw holes, the inner sleeve can provide uniform radial support for the spiral steel pipe, thereby comprehensively improving the overall structural performance of the pipe body.

[0013] 2. Through the setting of the chute and the shock-absorbing filler, the precise docking of the chute and the fixed welding plate ensures the positioning accuracy during the installation of the inner sleeve layer, enabling the fasteners to be quickly and accurately aligned and fixed, greatly simplifying the assembly process. The specially selected rock wool shock-absorbing filler, through dense filling of the grid space, not only effectively suppresses the structural resonance phenomenon caused by vibration transmission, but also blocks the transmission of noise generated by the fluid medium, giving the pipeline system both excellent mechanical performance and environmentally friendly characteristics.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides, for example Figure 1-3 The spiral steel pipe shown includes a spiral steel pipe 1 and a reinforcing rib 2 spirally arranged on the outside of the spiral steel pipe 1. Multiple fixing screws 3 are provided on the outer side of the spiral steel pipe 1, multiple fixing welding plates 7 are provided on the inner wall of the spiral steel pipe 1, an inner sleeve layer 8 is provided inside the spiral steel pipe 1, multiple ring welding plates 9 are provided on the outer side of the inner sleeve layer 8, connecting welding plates 13 are arranged horizontally between the ring welding plates 9, multiple fixing screw holes 11 are provided on the connecting welding plates 13, and shock-absorbing filler 12 is provided in the gap between the ring welding plates 9 and the connecting welding plates 13.

[0020] In this embodiment, the spiral steel pipe is a steel pipe made by rolling and welding steel strips or plates into a spiral shape. The spiral steel pipe is usually used to transport fluids or gases. During installation, it is connected and fixed by the butt bolts 5 and butt bolt holes 4 on the connecting flange 6 to ensure the sealing and pressure bearing capacity of the spiral steel pipe 1. Due to its structural characteristics, the spiral steel pipe 1 exhibits high stability in long-distance transportation and can withstand large internal and external pressures. In addition, the spiral steel pipe can also be used as a structural support component in bridges, buildings or other infrastructure projects, playing its role in load bearing and anti-deformation. The introduction of the reinforcing rib 2 not only optimizes the mechanical properties of the spiral steel pipe 1, but also makes it more advantageous in specific application scenarios. For example, in buried pipeline projects that need to resist large soil pressure or external impacts, the reinforcing rib 2 can effectively disperse stress and prevent local dents or twists in the pipeline. In some structures that need to reduce self-weight but maintain strength, the reinforcing rib structure can improve the load-bearing capacity of the pipeline without significantly increasing the amount of material used.

[0021] like Figure 1 , Figure 2 and 3 As shown, the fixed welding plate 7 is welded to the spiral steel pipe 1. The fixed welding plate 7 is a long strip of metal block. The fixed welding plate 7 can provide initial support for the spiral steel pipe 1 from the inner wall. The annular welding plate 9 is welded to the inner sleeve layer 8. The annular welding plate 9 can strengthen the outer layer of the inner sleeve layer 8. The connecting welding plate 13 is horizontally connected to the annular welding plate 9. The connecting welding plate 13 is welded to both the annular welding plate 9 and the inner sleeve layer 8. The cross-mesh structure formed by the annular welding plate 9 and the connecting welding plate 13 can not only strengthen the outside of the inner sleeve layer 8, but also provide support for the inner wall of the spiral steel pipe 1. The shock-absorbing filler 12 is adhered and fixed to the annular welding plate 9 and the connecting welding plate 1. In the gap formed between 3, the shock-absorbing filler 12 is made of rock wool. The shock-absorbing filler 12 can not only dampen the inner sleeve 8, but also play a certain role in sound insulation. A groove 10 is provided between the annular welding plate 9 and the connecting welding plate 13. The inner sleeve 8 can be connected to the fixed welding plate 7 through the groove 10. The inner sleeve 8 can be fixedly installed to the spiral steel pipe 1 through the fixing screws 3 and fixing screw holes 11. Connecting flanges 6 are provided at both ends of the spiral steel pipe 1. Connecting screws 5 and connecting screw holes 4 are provided on the connecting flanges 6 at both ends. The spiral steel pipe 1 is fixedly connected through the connecting flanges 6, connecting screws 5 and connecting screw holes 4.

[0022] Preferably, through the arrangement of the inner sleeve layer 8, the annular welding plate 9, the connecting welding plate 13, the fixing screw 3, the fixing screw hole 11, and the fixing welding plate 7, the fixing welding plate 7 is welded to the inner wall of the spiral steel pipe 1 to form preliminary support and fixation. The annular welding plate 9 and the connecting welding plate 13 form a grid structure by cross welding, which can strengthen the outer side of the inner sleeve layer 8. At the same time, with the locking structure of the fixing screw 3 and the fixing screw hole 11, the inner sleeve layer 8 can support the spiral steel pipe 1, which greatly improves the overall structural strength of the spiral steel pipe 1.

[0023] Preferably, by setting the groove 10 and the shock-absorbing filler 12, when the inner sleeve 8 is connected to the spiral steel pipe 1, the groove 10 can be connected to the fixed welding plate 7. Through the positioning and cooperation of the groove 10 and the fixed welding plate 7, the inner sleeve 8 can be accurately positioned during installation, ensuring that the fixing screw 3 can be accurately aligned and fixed with the fixing screw hole 11, which facilitates the fixed installation of the inner sleeve 8 and the spiral steel pipe 1. The rock wool shock-absorbing filler 12, by filling the mesh gaps, can suppress the structural resonance generated during vibration transmission and block the transmission of noise caused by the fluid medium, significantly improving the environmental friendliness of the pipeline.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
