Description

Technical Field

[0001] This utility model relates to the field of construction, and in particular to a rapid steel structure connection device for steel structure construction. Background Technology

[0002] In modern architecture, bridge construction, and large-scale industrial facility construction, steel structures are widely used due to their advantages such as high strength, light weight, and short construction period. During steel structure construction, the connection of steel structure components is a crucial step in ensuring the overall structural stability and safety.

[0003] Currently, common steel structure connection methods mainly include welding and bolting. While welding can achieve strong connections, it suffers from slow construction speed, high skill requirements for operators, susceptibility to deformation and residual stress during welding, and significant impact from environmental factors (such as humidity and wind) on on-site welding, making it difficult to guarantee weld quality. Bolting, while relatively convenient to install, requires pre-machining numerous bolt holes on the steel structure components, which can lead to misalignment during installation, resulting in low installation efficiency. Furthermore, the fatigue resistance and sealing performance of the connection points need improvement. In addition, existing steel structure connection devices often fail to simultaneously meet the requirements of rapid installation, precise positioning, and reliable connection, making them unsuitable for complex and changing construction site environments and hindering the improvement of steel structure construction efficiency and quality.

[0004] Therefore, there is an urgent need to develop a docking device for steel structure construction that can achieve rapid, accurate, and stable docking, in order to overcome the shortcomings of existing technologies and meet the needs of efficient and high-quality construction of modern steel structure projects. Summary of the Invention

[0005] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0006] To achieve the above objectives, the first aspect of this utility model proposes a quick steel structure docking device for steel structure construction, including a male seat, a female seat, and a connecting sleeve. One end face of the male seat is provided with a locking block and a first connecting hole. The female seat has a convex structure and a locking groove and a second connecting hole respectively mate with the locking block and the first connecting hole on its protruding surface. The connecting sleeve is fitted between the male seat and the female seat, and the side of the connecting sleeve is provided with several steel limiting grooves.

[0007] As an improvement, the number of steel limiting grooves is no more than one, and they are evenly distributed on the side of the steel limiting grooves.

[0008] As an improvement, the male seat, female seat, and connecting sleeve are all provided with a uniformly arranged limiting hole.

[0009] As an improvement, the male seat, female seat, and connecting sleeve are all made of high-carbon steel.

[0010] Beneficial effects

[0011] Rapid and precise alignment enhances construction efficiency: The male connector's locking blocks and the female connector's locking slots, along with connecting hole one and connecting hole two, work together to form a precise positioning and rapid fitting structure. During construction, simply snapping the corresponding parts of the male and female connectors together completes the initial positioning, eliminating the need for complex calibration and adjustment processes. Compared to traditional welding and bolt connections, this significantly shortens the alignment time of steel structure components, substantially improving construction efficiency, and is particularly suitable for large-scale steel structure projects with tight schedules.

[0012] Enhancing connection stability and reliability: The connecting sleeve is fitted between the male and female seats, fitting tightly with both. At the same time, the steel limiting groove on the side of the connecting sleeve can effectively limit the steel, preventing the steel from shifting or loosening during the docking process. The limiting holes evenly distributed on the male, female seats, and connecting sleeve can be used to further enhance the tightness and stability of the connection by inserting limiting pins or bolts, effectively improving the overall load-bearing capacity and deformation resistance of the steel structure, and ensuring the safety of the engineering structure.

[0013] Optimize structural design to ensure construction quality: The number of steel limiting grooves is no more than 8 and they are evenly distributed. This can reasonably control the structural strength and weight of the connecting sleeve and ensure uniform limiting of the steel, avoiding stress concentration caused by uneven limiting. The male and female seats and connecting sleeves are made of high-carbon steel, which has high strength, high hardness and good wear resistance. They can withstand large loads and external forces, reduce wear and damage to components during use, extend the service life of the device, and at the same time ensure the quality and durability of the steel structure connection parts.

[0014] Improved applicability and versatility: The modular design of the device makes it suitable for connecting steel structure components of various specifications and types. By adjusting the size and number of steel limiting grooves, it can be adapted to steel of different sizes. The standardized structural design of the male and female seats and connecting sleeves facilitates manufacturing and on-site replacement and maintenance, reduces construction costs, improves construction flexibility and versatility, and meets the needs of different engineering scenarios.

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] Example 1

[0023] This embodiment provides a specific implementation method for a rapid steel structure connection device used in steel structure construction.

[0024] This steel structure quick-connect device includes a male connector, a female connector, and a connecting sleeve, all three of which are made of high-carbon steel using a precision forging process to ensure high strength and good wear resistance. The male connector has a square block structure, with two symmetrically distributed rectangular locking blocks milled on one end face. A 12mm diameter connecting hole is drilled next to each locking block. The female connector is designed with a convex structure. Rectangular locking grooves, matching the shape and size of the locking blocks, and a second connecting hole, also 12mm in diameter, are machined on its protruding surface corresponding to the positions of the locking blocks and connecting hole one.

[0025] The connecting sleeve is a hollow cylindrical tube, with its inner diameter slightly larger than the outer diameter of the male and female seats after docking. Six steel limiting grooves are evenly distributed along the circumference of its side. Each limiting groove has a trapezoidal cross-section, with an upper width of 20mm, a lower width of 15mm, and a depth of 10mm. Simultaneously, eight limiting holes with a diameter of 8mm are evenly provided along the edges of the male seat, female seat, and connecting sleeve.

[0026] In practical construction applications, the two steel structures to be connected are first installed on the male and female seats respectively, and the steel limiting grooves are used to initially fix the steel structures. Next, the locking blocks of the male seat are aligned with the locking grooves of the female seat, and the first connecting hole is aligned with the second connecting hole. The male seat is then pushed to quickly engage with the female seat. Then, the connecting sleeve is inserted from the outside of the male and female seats, so that the limiting holes on the connecting sleeve correspond one-to-one with the limiting holes on the male and female seats. Finally, high-strength bolts with a diameter of 8mm are inserted through the limiting holes and tightened with nuts to complete the rapid and stable connection of the two steel structures.

[0027] Example 2

[0028] This embodiment is based on Embodiment 1, but with some structural parameters adjusted.

[0029] The number of steel limiting grooves on the side of the connecting sleeve is set to four, evenly distributed on its side. The cross-sectional shape of each steel limiting groove is changed to U-shape, with an opening width of 25mm and a depth of 12mm, to accommodate the installation requirements of steel of different sizes and specifications. At the same time, the diameter of the upper limiting hole of the male and female seats and the connecting sleeve is adjusted to 10mm to accommodate thicker connecting parts and further enhance the tightness of the connection.

[0030] During construction, for small and lightweight steel structure components, they are first placed in the steel limiting grooves of the male and female seats, and the U-shaped structure of the limiting grooves is used to stabilize and limit the steel structure. Then, following the docking steps in Example 1, the male and female seats are engaged and the connecting sleeve is put on. Finally, a 10mm diameter bolt is passed through the limiting hole for fastening, realizing the rapid docking of small steel structure components, and the connection strength meets the engineering requirements.
