Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of steel pipes, and particularly relates to a special-shaped steel pipe with good bending resistance. BACKGROUND

[0002] Steel pipes are hollow metal pipes made of steel material, with a hollow structure and a circular or other geometric cross-section. Steel pipes are widely used in various industries due to their high strength, durability, and versatility.

[0003] In the application number 202122972794.6, a special-shaped steel pipe with excellent bending resistance is disclosed. The design of the first, second, and third straight thickening sections increases the thickness of the special-shaped steel pipe on both sides and the bottom, thereby improving the impact strength of the special-shaped steel pipe and further improving the bending resistance of the special-shaped steel pipe. The triangular cross-section design of the special-shaped steel pipe further improves the bending and torsional resistance of the special-shaped steel pipe. The combination of straight and arc sections makes the structure of the special-shaped steel pipe more stable and less prone to deformation, and also improves the space utilization. SUMMARY

[0004] The utility model aims at providing a special-shaped steel pipe with good bending resistance to solve the problem of the above background technology, which improves the overall bending resistance by setting different pipe sections, but the inner wall is prone to deformation or cracking due to stress concentration, affecting the strength and durability. The outer wall may still have local buckling under extreme conditions, and the impact resistance is limited.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a special-shaped steel pipe with good bending resistance, comprising: an inner pipe and an outer pipe of the special-shaped steel pipe, a plurality of partitions are installed in the inner pipe, the plurality of partitions divide the inner pipe into a plurality of independent chambers, a first straight section, an arc section, and a second straight section are provided in each partition, the first straight section and the second straight section are located at both ends of the arc section, and the first straight section and the second straight section are connected to the inner wall of the inner pipe.

[0006] Preferably, a support frame is installed between the plurality of partitions, and the support frame is in the shape of a cross.

[0007] Through the above technical solutions:

[0008] In use, the special-shaped steel pipe adopts a multi-chamber composite structure, breaking the limitations of traditional single-chamber steel pipes. By setting multiple partitions inside the inner pipe, the inner pipe is successfully divided into multiple independent chambers. This design not only enhances the overall strength of the steel pipe, but also gives it higher torsional performance and load-bearing capacity.

[0009] Application in high-rise buildings

[0010] In the structural columns of high-rise buildings, the use of multi-chamber composite steel pipes can effectively suppress the local buckling phenomenon of the steel pipe wall. The presence of partitions allows the steel pipe to more effectively distribute stress and prevent local deformation when under heavy pressure.

[0011] Material filling optimization

[0012] Different chambers can be filled with different materials according to actual stress conditions. For example, one chamber can be filled with high-strength concrete to enhance load-bearing capacity, and another chamber can be filled with lightweight foam material to reduce overall weight. This flexible material filling method further optimizes the mechanical properties of the steel pipe, allowing it to perform optimally in different application scenarios.

[0013] Multi-functional pipe system

[0014] Multiple independent chambers can also be applied to pipe systems to achieve independent delivery of multiple fluids. This design not only improves the efficiency and safety of the pipe system, but also reduces the space occupied by the pipe. The design composed of a first straight segment, an arc segment, and a second straight segment makes it difficult for fluids to accumulate or jam during transportation. This streamlined structure greatly improves the smoothness of the inner surface of the steel pipe, reducing resistance during fluid transportation.

[0015] Efficient fluid transportation

[0016] Whether it's a liquid or a gas, this streamlined design ensures smooth flow inside the steel pipe, reducing energy loss and improving transportation efficiency.

[0017] Anti-clogging design

[0018] The presence of the arc segment effectively prevents fluid accumulation and clogging during transportation, extending the service life of the steel pipe.

[0019] Structural stability

[0020] Support frames are installed between the partitions, which mainly serve to enhance the stability and bending resistance of the structure. The support frames are firmly fixed to the partitions through welding or other methods, ensuring that they do not loosen or fall off during use. The support frames are in the shape of a cross, which can provide multi-directional support to the partitions, further improving the bending resistance of the steel pipe. The cross-shaped support frame can evenly distribute stress in all directions, ensuring that the steel pipe remains structurally stable when subjected to complex loads. Whether it is axial, radial, or angular load, the cross-shaped support frame can provide effective support to prevent deformation or damage to the steel pipe.

[0021] In summary, through the comprehensive use of multi-chamber composite structure, streamlined internal design, and support frame reinforced structure, the special-shaped steel pipe has achieved significant improvement in torsional performance, carrying capacity, structural stability, and fluid transportation efficiency. Its innovative design and multi-functionality make it have broad application prospects in multiple fields, and can meet the needs of different industries for high-performance steel pipes.

[0025] In use,

[0026] Innovative design of protruding blocks

[0027] Structural features: The outer wall of the outer pipeline is uniformly provided with a plurality of arc-shaped protruding blocks. Each protruding block forms a series of protruding structures on the outside of the pipeline, which not only optimizes the appearance of the pipeline, but also endows the pipeline with unique mechanical properties.

[0028] Improved compression resistance: The arc-shaped design of the protruding blocks is similar to an arch structure, which can effectively disperse pressure and distribute concentrated stress to a larger area when the pipeline is subjected to external pressure, thereby significantly enhancing the compression resistance of the pipeline. This design is particularly suitable for applications that require high pressure or impact resistance, such as oil and gas transportation pipelines.

[0029] Anti-skid and anti-displacement: The presence of protruding blocks increases the surface area and roughness of the outer wall of the pipeline, thereby increasing the friction between the pipeline and the external environment. In applications such as buried or underwater pipeline laying, this design can effectively prevent the pipeline from sliding or shifting, ensuring the stability and safety of the pipeline.

[0030] Protective Role: The raised blocks also serve a protective role for the outer wall of the pipe, preventing direct impacts from external objects and reducing the risk of potential damage. This protective mechanism is particularly crucial in harsh external environments, extending the service life of the pipe.

[0031] Reinforcing Function of Support Bars

[0032] Connection and Support: Between two adjacent raised blocks, there is a support bar connected by welding. The support bar not only plays a connecting role, but also enhances the stability and strength of the entire structure. Its shape and size can be customized according to specific needs to provide the best support effect.

[0033] Stress Dispersion: The presence of support bars enhances the connection strength between raised blocks, making the entire pipe outer wall structure more stable. It can effectively disperse and transfer stress, preventing raised blocks from deforming or damaging when subjected to external pressure. This design is particularly important when the pipe is subjected to complex loads, improving the overall load-bearing capacity of the pipe.

[0034] Bending Resistance: The design of the support bar also improves the bending resistance of the pipe. When the pipe is subjected to bending force, the support bar can provide additional support to prevent excessive deformation of the pipe. This feature allows the pipe to maintain good structural integrity in applications with high bending stress, such as bridges and high-rise buildings.

[0035] Multifunctional Application of Sheath

[0036] Structural and Material Diversity: Multiple sheaths are installed on the outer wall of the outer pipe, evenly distributed on the outer wall of the outer pipe. The design of the sheath can use different materials and shapes to meet different application needs. For example, in a corrosive environment, corrosion-resistant materials can be selected; in high-temperature or low-temperature environments, materials with thermal insulation properties can be selected.

[0037] Protection and Prevention: The main function of the sheath is to protect the outer wall of the pipe, preventing external environments from causing corrosion, wear and damage to the pipe. In harsh chemical environments, the sheath can be made of corrosion-resistant materials to extend the service life of the pipe. In addition, the sheath can also prevent mechanical damage to the pipe, such as wear and tear.

[0038] Thermal Insulation and Heat Preservation: The sheath also has thermal insulation and heat preservation functions. In high-temperature or low-temperature environments, the sheath can effectively reduce the heat exchange between the inside and outside of the pipe, maintaining the stability of the internal temperature of the pipe. This is particularly important for pipe systems that require precise temperature control, such as certain applications in the chemical and petroleum industries.

[0039] Aesthetics and Identification: The design of the sheath also beautifies the appearance of the pipeline, making it more aesthetically pleasing. In addition, the sheath can be used to identify the pipeline, such as distinguishing different types of pipelines by different colors or markings. This provides a convenient way to identify and manage complex pipeline systems, such as urban water supply and drainage systems.

The main function of the reinforcing rib is to connect the two layers of pipelines and enhance the strength and stability of the entire structure. This design makes the reinforcing rib a key support structure inside the pipeline, significantly improving the overall performance of the pipeline.

[0049] Spiral Tight Winding: The reinforcing rib is in a spiral shape, tightly wound between the inner and outer pipes. This design allows the reinforcing rib to form a continuous support structure along the pipe axis. The spiral shape not only increases the contact area but also makes the stress distribution more uniform, thereby improving the overall load-bearing capacity of the pipe.

[0050] Uniform Stress Distribution: The spiral reinforcing rib can evenly distribute stress. No matter where the load comes from, it can effectively disperse and resist.

This design improves the tensile and compressive strength of the entire pipe, allowing it to remain stable under various complex working conditions.

[0053] Prevent Deformation: Due to the presence of the reinforcing rib, the pipe can effectively prevent local buckling or overall deformation when subjected to external loads. This feature is particularly important in applications requiring high strength and stability, such as high-rise buildings and bridge structures.
