Description

Technical Field

[0001] This invention relates to the field of steel component processing technology, and more specifically, to a process for processing and manufacturing H-shaped steel components. Background Technology

[0002] Steel structural components have comprehensive advantages such as light weight, factory manufacturing, quick installation, short construction period, good seismic performance, fast investment recovery, and less environmental pollution. Compared with reinforced concrete structures, they have unique advantages in terms of "height, size, and lightness". Globally, especially in developed countries and regions, steel components are being used in the field of building engineering in a reasonable and widespread manner.

[0003] In order to improve the quality of the steel component itself, the surface of the existing H-beam steel components needs to be pre-treated during the manufacturing process.

[0004] However, during the blanking process before steel components are processed, transverse micro-cracks that are difficult to observe may appear on the surface of the steel, affecting the safety and service life of H-beam steel components. The biggest difference between these cracks and ordinary cracks is that ordinary cracks are visible to the naked eye and cannot be ignored, while micro-cracks generally require a microscope to see. During use, unrepaired micro-cracks will gradually enlarge, producing gaps of a certain size, leading to a reduction in the quality of the steel components, greatly shortening their service life, and posing certain safety hazards. Summary of the Invention

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, the present invention aims to provide a processing technology for H-shaped steel components. This technology incorporates a specially designed crack detection sleeve. This sleeve decolorizes the color-developing ink applied to the surface of the steel component through a chemical reaction with the neutral solvent sodium chloride, while preserving the original color of the ink applied within the cracks. This allows technicians to easily observe and quickly locate cracks, enabling timely repair. Furthermore, the reflective powder within the color-developing ink makes the cracks more easily visible to the naked eye through light refraction. Even minute cracks can be easily found by technicians. Compared to the existing method of using a magnifying glass to locate cracks, this method not only effectively shortens the time required to locate cracks but also improves the efficiency of crack treatment, preventing the omission of cracks on the surface of the steel component and thus avoiding a reduction in the quality and service life of the steel component.

[0007] Technical solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A process for fabricating H-beam steel components includes the following steps:

[0010] S1. Crack detection on steel plate surface: Install the crack detection sleeve on the steel plate to inspect the surface of the steel plate;

[0011] S2, Crack Marking on Steel Plate Surface: Push the crack detection sleeve to move it on the steel plate and mark the cracks.

[0012] S3. Determine the location of the crack: After marking, use a flashlight to observe the crack at the marked location. After determining the crack, the staff will repair it.

[0013] S4. Processing and Fixing: The steel plate is leveled and cut as a whole, then the workers perform H-shaped assembly and welding operations on the steel plate, and finally the steel plate is inspected.

[0014] Furthermore, the crack detection sleeve in S1 includes a partition fixed at the center of the crack detection sleeve, and a first coating cotton and a second coating cotton are fixedly connected to the inner walls of the left and right sides of the crack detection sleeve, respectively, and both the first coating cotton and the second coating cotton are fixedly connected to the partition.

[0015] Furthermore, including steel components, the crack detection sleeve in S1 includes a partition fixed at the center of the crack detection sleeve. A first coating cotton and a second coating cotton are fixedly connected to the inner walls of the left and right sides of the crack detection sleeve, respectively, and both the first and second coating cottons are fixedly connected to the partition. This allows for the use of a specially designed crack detection sleeve. The crack detection sleeve can decolorize the color-developing ink applied to the surface of the steel component through a chemical reaction produced by the neutral solvent sodium chloride, while maintaining the original color-developing effect of the ink applied within the crack. This facilitates technicians' observation and quick location of the crack, enabling timely repair. Simultaneously, the reflective powder within the color-developing ink makes it easier to observe with the naked eye through light refraction. Even tiny cracks can be easily found by technicians. Compared to the existing method of using a magnifying glass to find cracks, this not only effectively shortens the time spent finding crack locations but also improves the efficiency of crack treatment, preventing the omission of cracks on the surface of the steel component and thus reducing the quality and service life of the steel component.

[0016] Furthermore, the crack detection sleeve is filled with color-developing ink on the upper side of the first coating cotton, and the steel component is filled with a clearing agent on the upper side of the second coating cotton. This allows the color-developing ink to cover the surface of the steel component, and the clearing agent can make the color-developing ink fade, making it easier to mark the cracks and facilitate observation by staff.

[0017] Furthermore, a shrinkage membrane is fixedly connected to the upper side wall of the second coating cotton, and multiple evenly distributed shrinkage holes are drilled on the shrinkage membrane. Multiple evenly distributed stirring mechanisms are fixedly connected to the first coating cotton, which can effectively reduce the amount of clearing agent applied and avoid excessive clearing agent flowing into the crack, causing the color developing ink in the crack to lose color.

[0018] Furthermore, the crack detection sleeve is fixedly connected to a dispensing port on the upper side of both the first and second coated cotton, and a dispensing cap is threaded onto the upper end of the dispensing port, which allows technicians to easily add color-developing ink and clearing agent.

[0019] Furthermore, the lower sidewall of the first coated cotton is fixedly connected with a plurality of evenly distributed penetrating fibers, which are made of plastic material. This helps the color developing ink to quickly penetrate into the crack, avoiding the inability to penetrate due to the surface tension of the liquid, thus preventing the crack from being missed.

[0020] Furthermore, the stirring mechanism includes multiple elastic support rods fixed to the first coated cotton, each elastic support rod being fixedly connected to a shaking ball, and each shaking ball being fixedly connected to multiple evenly distributed agitating cilia, which can stir the color developing ink while moving, thus avoiding sedimentation that would affect the color developing effect of the color developing ink.

[0021] Furthermore, the color-developing ink is made by mixing phenolphthalein reagent, alkaline solution and reflective powder in a ratio of 1.5:0.5:1, which can mark cracks, and the added reflective powder is more easily noticed by workers under light.

[0022] Furthermore, the clearing agent is a neutral sodium chloride solution, which can cause the color-developing ink to lose its color while retaining the color of the color-developing ink in the cracks.

[0023] Furthermore, multiple cleaning strips are fixedly connected to the lower side wall of the second coated cotton, and the multiple cleaning strips are evenly distributed to effectively enhance the removal of reflective powder. Beneficial effects

[0024] Compared with the prior art, the advantages of this invention are:

[0025] (1) This solution can be equipped with a specially designed crack detection sleeve. The crack detection sleeve can decolorize the color-developing ink applied to the surface of the steel component through a chemical reaction produced by the neutral solvent sodium chloride, and keep the original color-developing ink applied to the crack. This makes it convenient for technicians to observe and quickly find the crack location, so that the crack can be repaired in time. At the same time, the reflective powder in the color-developing ink can be more easily observed by the naked eye through the refraction of light. Even tiny cracks can be easily found by technicians. Compared with the existing technology of using a magnifying glass to find cracks, this solution not only effectively shortens the time to find the crack location, but also improves the efficiency of crack treatment, avoids missing cracks on the surface of the steel component, and reduces the quality and service life of the steel component.

[0026] (2) The steel component is filled with color-developing ink on the upper side of the first coating cotton and with clearing agent on the upper side of the second coating cotton. This allows the color-developing ink to cover the surface of the steel component and the clearing agent to make the color-developing ink lose its color, making it easier to mark the cracks and for staff to observe.

[0027] (3) A shrinkable membrane is fixedly connected to the upper side wall of the second coating cotton. Multiple shrinkable holes are drilled on the shrinkable membrane. Multiple uniformly distributed stirring mechanisms are fixedly connected to the first coating cotton. This can effectively reduce the amount of clearing agent applied and prevent excessive clearing agent from flowing into the crack, causing the color developing ink in the crack to lose its color.

[0028] (4) A filling port is fixedly connected to the steel component on the upper side of the first coating cotton and the second coating cotton. The upper end of the filling port is threaded with a filling cap, which makes it convenient for technicians to add color developing ink and clearing agent.

[0029] (5) The lower side wall of the first coating cotton is fixedly connected with multiple evenly distributed penetrating fibers, and the penetrating fibers are made of plastic material, which can help the color developing ink to quickly penetrate into the crack, and avoid the inability to penetrate due to the surface tension of the liquid, thus missing the crack.

[0030] (6) The stirring mechanism includes multiple elastic support rods fixed on the first coated cotton. Each elastic support rod is fixedly connected to a shaking ball, and multiple evenly distributed stirring cilia are fixedly connected to the shaking ball. The stirring mechanism can stir the color developing ink while moving, so as to avoid precipitation and affect the color developing effect of the color developing ink.

[0031] (7) The color-developing ink is made by mixing phenolphthalein reagent, alkaline solution and reflective powder in a ratio of 1.5:0.5:1. It can mark cracks, and the added reflective powder is more easily noticed by staff under light.

[0032] (8) The clearing agent is a neutral sodium chloride solution, which can cause the color developing ink to lose its color while retaining the color of the color developing ink in the crack.

[0033] (9) Multiple cleaning strips are fixedly connected to the lower side wall of the second coated cotton, and the multiple cleaning strips are evenly distributed to effectively enhance the removal of reflective powder. Attached Figure Description
