Description

Technical Field

[0001] This utility model relates to the technical field of special-shaped steel, and in particular to the technical field of high-strength corrosion-resistant cold-drawn special-shaped steel. Background Technology

[0002] Special-shaped steel is a shorthand for complex and irregular cross-section steel. It is a type of steel and is different from the name of simple cross-section steel. Depending on the process, it can be further divided into hot-rolled special-shaped steel, cold-drawn (cold-stretched) special-shaped steel, cold-bent special-shaped steel, welded special-shaped steel, etc.

[0003] Currently, many irregularly shaped steel sections experience misalignment and displacement when connected to other components, leading to unreliable positioning of the irregularly shaped steel and reduced safety performance.

[0004] To address the problems mentioned above, for example, application number CN201320562820.0 discloses a grooved special-shaped steel body. The steel body has multiple grooves evenly distributed at equal intervals along its outer circumference. The grooves have trapezoidal cross-sections and locking teeth. The number of grooves can be two, four, eight, or sixteen. The grooves are integrated with the steel body. This utility model provides a grooved special-shaped steel body with reliable and stable stress distribution, enabling rigid assembly and connection between the special-shaped steel and other components. After connection, no displacement occurs, positioning is more precise, and excellent safety is ensured. It also expands the application range of special-shaped steel.

[0005] Although the above structure can achieve rigid assembly and cooperation between the irregular steel and other components, the irregular steel is exposed to the outdoors for a long time and is affected by environmental factors, resulting in surface weathering.

[0006] To address the problems mentioned above, for example, application number CN202122595420.7 discloses a multi-curved irregular steel structure, including steel plates, with a protective layer coated on the surface of each steel plate. The protective layer includes a surface layer and an anti-corrosion layer. The inner side of the surface layer is coated onto the outer wall of the steel plate, and the outer wall of the surface layer is coated with an anti-corrosion layer. This prevents the steel plates from weathering due to long-term environmental factors. Through the cooperation between the steel plates and the protective layer, a surface layer is first coated on the surface of four steel plates, and then an anti-corrosion layer is coated on the surface of the surface layer. The anti-corrosion layer is a vinyl resin synthesized by reacting methacrylic acid and bisphenol A epoxy resin, which gives the steel plates anti-corrosion properties and prevents the steel plates from weathering due to long-term environmental factors.

[0007] However, the above structure still has the following drawbacks:

[0008] Although the above structure improves the corrosion resistance of irregular steel, it lacks good compressive strength. The irregular shape of the overall structure is prone to being flattened, bent or broken under pressure. Summary of the Invention

[0009] The purpose of this invention is to solve the problems in the existing technology by proposing a high-strength, corrosion-resistant, cold-drawn special-shaped steel, which can improve the overall strength of the special-shaped steel, making it less prone to breakage, and also improve its corrosion resistance.

[0010] To achieve the above objectives, this utility model proposes a high-strength, corrosion-resistant, cold-drawn special-shaped steel, comprising a special-shaped steel body, a first accommodating cavity, a pressure-resistant structure, a crossbar, a slider, a first buffer spring, a vertical rod, a fixing block, a connecting rod, a second accommodating cavity, and a reinforcing structure. The special-shaped steel body has a first accommodating cavity inside, and a pressure-resistant structure is provided within the first accommodating cavity. The pressure-resistant structure includes a crossbar, a slider, a first buffer spring, a vertical rod, a fixing block, and a connecting rod. The crossbar is transversely positioned within the first accommodating cavity, and two sliders are slidably connected to the crossbar. First buffer springs are sleeved on both ends of the crossbar, with one end connected to the inner sidewall of the first accommodating cavity and the other end connected to the sidewall of the slider. A vertical rod is provided in the middle of the inner top wall of the first accommodating cavity, and a fixing block is fixedly connected to the outside of the vertical rod. Connecting rods are installed on both sides of the fixing block, and the other end of the connecting rod is connected to the top of the slider. The special-shaped steel body has second accommodating cavities on both sides inside, and a reinforcing structure is provided within each second accommodating cavity.

[0011] Preferably, the inner bottom wall of the first accommodating cavity is provided with an elastic support column corresponding to the vertical rod, the top of the elastic support column is connected to the bottom of the vertical rod, and a second buffer spring is sleeved on the outside of the elastic support column.

[0012] Preferably, the reinforcing structure includes a first reinforcing rib and a second reinforcing rib, wherein the first reinforcing rib is located on both sides of the second accommodating cavity, and the second reinforcing rib is located between the first reinforcing ribs.

[0013] Preferably, the second reinforcing rib has an I-shaped structure.

[0014] Preferably, the surface of the irregular steel body is coated with an anti-corrosion coating layer.

[0015] Preferably, the surface of the shaped steel body is provided with a number of V-shaped guide grooves, which are arranged in parallel, and the depth of one end of the V-shaped guide groove is lower than the depth of the other end.

[0016] The beneficial effects of this utility model are:

[0017] 1. This utility model, by setting up an anti-compression structure, when the shaped steel body is subjected to downward extrusion from the outside, firstly, the vertical rod is subjected to extrusion and moves downward. During the downward movement of the vertical rod, pressure is applied to the elastic support column and the second buffer spring, so that the elastic support column and the second buffer spring convert the impact kinetic energy into potential energy for storage. At the same time, during the downward movement of the vertical rod, the fixed block descends synchronously, thereby driving the connecting rods on both sides to move. As the connecting rods move, the slider slides on the horizontal bar, causing the slider to compress the first buffer spring. Through the elastic absorption and release of the first buffer spring, the elastic support column and the second buffer spring, the external impact force is gradually weakened, thereby achieving the anti-compression effect. This makes the shaped steel less prone to breakage when subjected to extrusion, thereby extending the service life of the shaped steel.

[0018] 2. This utility model, by setting a V-shaped guide channel, can drain the moisture on the shaped steel outward, making it less likely for the moisture to remain on the shaped steel for a long time, thereby reducing corrosion. At the same time, the surface is coated with an anti-corrosion coating layer, which can further play a role in corrosion prevention. Attached Figure Description

Detailed Implementation

[0023] See Figures 1 to 3This utility model discloses a high-strength, corrosion-resistant, cold-drawn special-shaped steel, comprising a special-shaped steel body 1, a first accommodating cavity 2, a pressure-resistant structure 3, a crossbar 301, a slider 302, a first buffer spring 303, a vertical rod 304, a fixing block 305, a connecting rod 306, a second accommodating cavity 4, and a reinforcing structure 5. The special-shaped steel body 1 has a first accommodating cavity 2 inside, and the first accommodating cavity 2 has a pressure-resistant structure 3 inside. The pressure-resistant structure 3 includes a crossbar 301, a slider 302, a first buffer spring 303, a vertical rod 304, a fixing block 305, and a connecting rod 306. The crossbar 301 is transversely arranged within the first accommodating cavity 2. Two sliders 302 are slidably connected to the crossbar 301. First buffer springs 303 are sleeved on both ends of the crossbar 301, and one end of the first buffer spring 303 is connected to the inner wall of the first accommodating cavity 2. The other end of the first buffer spring 303 is connected to the side wall of the slider 302. A vertical rod 304 is provided in the middle of the inner top wall of the first accommodating cavity 2. A fixing block 305 is fixedly connected to the outside of the vertical rod 304. Connecting rods 306 are installed on both sides of the fixing block 305. The other end of the connecting rod 306 is connected to the top of the slider 302. A second accommodating cavity 4 is provided on both sides of the interior of the special-shaped steel body 1. A reinforcing structure 5 is provided in the second accommodating cavity 4. When the vertical rod 304 moves downward, it drives the fixing block 305 to descend synchronously, thereby driving the connecting rods 306 on both sides to move. While the connecting rods 306 move, they drive the slider 302 to slide on the horizontal rod 301, so that the slider 302 compresses the first buffer spring 303. The elasticity of the first buffer spring 303 absorbs and releases the impact force from the outside, thereby gradually weakening the impact force.

[0024] See Figure 1 The inner bottom wall of the first accommodating cavity 2 is provided with an elastic support column 6 corresponding to the vertical rod 304. The top of the elastic support column 6 is connected to the bottom of the vertical rod 304, and a second buffer spring 7 is sleeved on the outside of the elastic support column 6. When the vertical rod 304 is subjected to a compressive force and moves downward, the vertical rod 304 applies pressure to the elastic support column 6 and the second buffer spring 7 during the downward movement, so that the elastic support column 6 and the second buffer spring 7 convert the impact kinetic energy into potential energy for storage, and then release it, so that the external impact force is gradually weakened, and the elastic support column 6 plays a supporting role for the vertical rod 304.

[0025] See Figure 1 The reinforcing structure 5 includes a first reinforcing rib 501 and a second reinforcing rib 502. The first reinforcing rib 501 is located on both sides of the second accommodating cavity 4, and the second reinforcing rib 502 is located between the first reinforcing rib 501. This can improve the impact resistance of the side of the shaped steel body 1, making it less likely to deform or be damaged when the shaped steel body 1 is hit from the side.

[0026] See Figure 1The second reinforcing rib 502 has an I-shaped structure, which can further strengthen the side strength of the special-shaped steel body 1.

[0027] See Figure 2 The surface of the shaped steel body 1 is coated with an anti-corrosion coating layer 8. The anti-corrosion coating layer 8 is a vinyl resin synthesized by reacting methacrylic acid and bisphenol A epoxy resin, which gives the surface of the shaped steel body 1 anti-corrosion properties.

[0028] See Figure 3 The surface of the shaped steel body 1 is provided with a plurality of V-shaped guide grooves 9. The V-shaped guide grooves 9 are arranged in parallel, and the depth of one end of the V-shaped guide groove 9 is lower than the depth of the other end. When rainwater falls onto the surface of the shaped steel body 1, the V-shaped guide grooves 9 guide the water to flow to the end with the lowest groove depth, so that the water can be discharged outward through the V-shaped guide grooves 9, making it less likely for water to stay on the shaped steel body 1 for a long time, thereby reducing the corrosion.

[0029] The working process of this utility model:

[0030] In the operation of this high-strength, corrosion-resistant, cold-drawn special-shaped steel, when the special-shaped steel body 1 is subjected to downward compressive force from the outside, the vertical rod 304 first moves downward under the compressive force. During the downward movement of the vertical rod 304, pressure is applied to the elastic support column 6 and the second buffer spring 7, causing the elastic support column 6 and the second buffer spring 7 to convert the impact kinetic energy into potential energy for storage. At the same time, during the downward movement of the vertical rod 304, the fixed block 305 descends synchronously, thereby causing the connecting rods 306 on both sides to move. As the connecting rods 306 move, the slider 302 slides on the horizontal rod 301, causing the slider 302 to compress the first buffer spring 303. Through the elastic absorption and release of the first buffer spring 303, the elastic support column 6, and the second buffer spring 7, the external impact force is gradually weakened, thereby achieving a compressive resistance effect. This makes the special-shaped steel less prone to breakage when subjected to compression, thus extending the service life of the special-shaped steel.

[0031] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
