Description

Technical Field

[0001] This utility model relates to the field of steel structure components, specifically a steel structure component that is easy to assemble. Background Technology

[0002] In modern architecture, industrial equipment manufacturing, and many other fields, steel structures have been widely used due to their advantages such as high strength, light weight, and short construction period. The assembly of components is crucial in the construction of steel structures. Traditional steel structure component assembly methods have many drawbacks. For example, some steel structure components are connected using extensive welding processes. This method not only requires extremely high technical skills from construction workers, but the high temperatures generated during welding can also cause localized deformation of the steel, affecting the overall precision and mechanical properties of the components. Moreover, after welding, any adjustments or disassembly of the structure are extremely difficult, often requiring significant manpower and resources for cutting and other operations, resulting in resource waste.

[0003] Some steel structural components using bolted connections, while easier to disassemble than welded ones to some extent, require precise alignment of multiple bolt holes during actual installation, making the process cumbersome and inefficient. Especially in large-scale construction projects, the bolting of numerous components consumes a significant amount of time, severely impacting project progress. Therefore, we propose a steel structural component that is easy to assemble. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a steel structure component that is easy to assemble, thus solving the above-mentioned problems.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solution: a steel structure component that is easy to assemble, comprising two concave steels arranged in mirror image, each of the two concave steels having an integrally formed side extension steel plate on one corresponding side, the side extension steel plates on the two concave steels being staggered vertically, the two side extension steel plates being connected by a positioning pin structure, and a bottom plate structure being provided at the bottom of the two concave steels.

[0006] Preferably, the base plate structure includes a base plate and a vertical steel plate. The top of the base plate is integrally formed with a vertical steel plate, which is located in the recesses inside two concave steel sections. Bolts are inserted through the vertical steel plate and the concave steel sections.

[0007] Preferably, a rectangular through-hole is provided on the side extension steel plate, and the positioning pin assembly is inserted into the inside of the rectangular through-hole.

[0008] Preferably, the positioning pin assembly includes a spring-loaded snap-fit ​​assembly and a positioning pin shaft. The spring-loaded snap-fit ​​assembly is disposed inside the rectangular through-hole, and the positioning pin shaft has a triangular notch on one side corresponding to the spring-loaded snap-fit ​​assembly, the triangular notch engaging with the spring-loaded snap-fit ​​assembly.

[0009] Preferably, the spring-loaded engagement assembly includes a spring and a pin. Inner grooves are provided on both sides of the inner wall of the rectangular through-hole. The spring is fixedly installed inside the inner groove. A pin is fixedly installed at the end of the inner groove. One end of the pin corresponding to the triangular notch is tapered. When the spring rebounds normally, the tapered end of the pin extends into the interior of the rectangular through-hole and engages with the triangular notch.

[0010] Preferably, a top opening is provided on the surface of the side extension steel plate at the position corresponding to the inner groove, and a slider is integrally formed on the pin at the position corresponding to the top opening, and the slider extends to the outside of the side extension steel plate through the top opening.

[0011] Compared with the prior art, this utility model provides a steel structure component that is easy to assemble, and has the following beneficial effects:

[0012] Significantly Improved Assembly Efficiency: This steel structure component employs a unique positioning pin structure and base plate structure design. During assembly, simply place the two mirror-shaped concave steel sections in position, allowing the staggered side extension steel plates to be quickly connected via the positioning pin assembly. The positioning pin shaft, combined with the spring-loaded snap-fit ​​assembly, simplifies operation; workers only need to slide the slider to easily insert and fix the positioning pin shaft. Compared to traditional bolt connections that require precise alignment of multiple bolt holes, this significantly saves assembly time, making it particularly suitable for the rapid assembly of numerous components in large-scale construction projects, greatly improving project progress.

[0013] Ensuring structural precision and stability: This method avoids the steel deformation problems caused by high temperatures in traditional welding processes, ensuring the overall precision of the components remains unaffected. The locating pin assembly and bolt connection method effectively distributes stress while ensuring a firm connection. The locating pin shaft engages with the pin through a triangular notch, combined with the elastic tightening effect of the spring, and the stable connection between the vertical steel plate and concave steel in the base plate structure via bolts. This ensures that the entire structure maintains good stability during long-term use, even under the influence of vibration, changes in ambient temperature, and other factors, reducing the risk of structural loosening and improving safety performance.

[0014] Facilitates later maintenance and adjustment: When adjustments or disassembly of the steel structure are required, the operation is simple. By sliding the slider, the connection between the positioning pin and the spring clip assembly can be easily released, allowing the two concave steel sections to separate. For the base plate structure, unscrewing the nuts on the bolts allows the base plate and vertical steel plate to be removed from the bottom of the concave steel sections. This convenient disassembly method greatly reduces the manpower and material costs of later maintenance, improves the maintainability of the steel structure, and extends its service life.

[0027] Structural Description:

[0028] Concave steel 1: This is a major component of the steel structure, and there are two of them arranged in a mirror image. Each of the two concave steel 1 has an integrally formed side extension steel plate 5 on its corresponding side, and its bottom is used to install the base plate structure, which consists of a base plate 2 and vertical steel plates 3. The structural design of the concave steel 1 provides the basic framework and support form for the entire component.

[0029] Base plate 2: It is part of the base plate structure and has a vertical steel plate 3 integrally formed on top. During installation, base plate 2 fits against the bottom of concave steel 1, which plays a role in sealing and stabilizing the bottom. It is the basic plate of the bottom of the entire component.

[0030] Vertical steel plate 3: Located on top of base plate 2, integrally formed on base plate 2. Vertical steel plate 3 is located in the recesses inside the two concave steel plates 1, and bolts 4 are inserted on it. It is connected to the concave steel plates 1 by bolts 4, thereby firmly installing the base plate structure at the bottom of the concave steel plates 1, enhancing the connection strength and stability of the bottom of the component.

[0031] Bolt 4: Used to connect the vertical steel plate 3 and the concave steel 1 in series. During installation, bolt 4 passes through the vertical steel plate 3 and the concave steel 1, and then a nut is installed on the other end of bolt 4 to achieve a fixed connection between the vertical steel plate 3 and the concave steel 1, ensuring a stable connection between the base plate structure and the concave steel 1.

[0032] Side extension steel plate 5: integrally formed on one side of the two concave steels 1, with the side extension steel plates 5 on the two concave steels 1 staggered vertically. A rectangular through-hole 6 is provided on the side extension steel plate 5 for installing a positioning pin assembly consisting of a positioning pin shaft 7, a spring 9, and a pin 10, etc., to achieve connection and positioning between the two concave steels 1. Simultaneously, a top opening 12 is provided on the surface of the side extension steel plate 5 corresponding to the position of the inner groove 8, for the movement of the slider 13.

[0033] Rectangular through-hole 6: This is located on the side extension steel plate 5 and is the insertion point for the positioning pin assembly. The positioning pin assembly connects and positions the two concave steel plates 1 through the rectangular through-hole 6, and its shape and size are adapted to the positioning pin assembly.

[0034] Positioning pin 7: Part of the positioning pin assembly, with a triangular notch 11 on one side corresponding to the spring-loaded snap-fit ​​assembly consisting of spring 9 and pin 10. During installation, the positioning pin 7 is inserted into the rectangular through-hole 6 and engages with the spring-loaded snap-fit ​​assembly through the triangular notch 11, thereby achieving positioning and fixed connection between the two concave steels 1.

[0035] Inner groove 8: Formed on the inner walls of both sides of the rectangular through-hole 6, used to install the spring 9 and the pin 10. The inner groove 8 provides installation space for the spring 9 and the pin 10 and guides the movement direction of the pin 10 so that it can accurately engage with the triangular notch 11 on the positioning pin 7.

[0036] Spring 9: Installed inside the inner groove 8, with one end fixed to the end of the inner groove 8. Spring 9 is elastic. When slider 13 is slid, spring 9 will be compressed and deformed; when slider 13 is released, spring 9 will rebound, pushing pin 10 closer to the positioning pin 7, so as to realize the engagement of pin 10 with triangular notch 11, which plays the role of connection and fixation.

[0037] Pin 10: Fixedly installed at the end of the inner groove 8, with one end tapered corresponding to the triangular notch 11. When the spring 9 returns, the tapered end of pin 10 extends into the rectangular through-hole 6 and engages with the triangular notch 11, thus fixing the positioning pin 7 and consequently fixing the two concave steels 1. A slider 13 is integrally formed on pin 10 at the position corresponding to the top opening 12, used to control the movement of pin 10.

[0038] Triangular notch 11: It is formed on one side of the positioning pin 7 corresponding to the spring snap-fit ​​assembly and is adapted to the tapered end of the pin 10. When the pin 10 moves closer to the positioning pin 7 under the action of the spring 9, the tapered end of the pin 10 will be inserted into the triangular notch 11, thereby fixing the positioning pin 7 and ensuring the stable connection between the two concave steels 1.

[0039] Top opening 12: Located on the surface of the side extension steel plate 5 at the position corresponding to the inner groove 8, for the extension and sliding of the slider 13. By operating the slider 13 to slide within the top opening 12, the movement of the pin 10 can be controlled, thereby realizing the installation and removal of the positioning pin 7.

[0040] Slider 13: One-piece molded at the position of the pin 10 corresponding to the top opening 12, extending to the outside of the side extension steel plate 5 through the top opening 12. The user can slide slider 13 to compress spring 9, causing pin 10 to retract, so as to insert or pull out positioning pin 7; when slider 13 is released, spring 9 rebounds, pin 10 extends and engages with triangular notch 11, completing the fixation of positioning pin 7.

[0041] Working principle: When snap-fit ​​is required, place the two concave steel plates 1 in a mirror image. At this time, the two side extension steel plates 5 are misaligned vertically. Slide the sliders 13 on both sides to the opposite side. Then, the spring 9 is compressed and deformed, and the positioning pin 7 is inserted into the rectangular through-hole 6. When the surface of the positioning pin 7 is flush with the surface of the side extension steel plate 5, release the slider 13. At this time, the spring 9 rebounds and pushes the pin 10 closer to the positioning pin 7. Then, the conical end of the pin 10 is snapped into the interior of the triangular notch 11 to complete the fixation. Then, the vertical steel plate 3 is snapped into the recess of the two concave steel plates 1. Then, the bottom plate 2 is attached to the bottom of the concave steel plates 1. Then, the bolt 4 is used to connect the vertical steel plate 3 and the concave steel plates 1 in series. Then, the nut is installed on the other end of the bolt 4 to complete the installation of the entire device.
