Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, and in particular to a steel structure for elevator shafts. Background Technology

[0002] As the elevator installation industry develops rapidly and its management becomes more standardized, higher requirements are being placed on construction quality and installation efficiency. Improving steel structure connection technology has become an important direction for technological innovation in the industry. This improvement not only enhances installation efficiency but also significantly improves energy efficiency by replacing traditional profiles with methods such as laser cutting and bending of steel plates. It also eliminates the drawbacks of traditional on-site welding and spraying processes, such as noise pollution and safety hazards caused by open flame operations. Utility Model Content

[0003] The purpose of this invention is to solve the problems of noise pollution and safety hazards caused by open flame operations in existing traditional on-site welding and spraying processes.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: It includes a steel column body, with steel beam bodies connected to both sides of the steel column body, load-bearing beams connected to the front and rear ends of the steel column body, clamping plates connected to the four corners of the inner wall of the steel column body, upper and lower interlocking grooves provided on the top of the steel column body, positioning holes provided at positions where the clamping plates match the steel beam bodies, steel column connection holes provided at positions where the steel column body matches the steel beam bodies, four sets of rectangular reinforcing plates equidistantly arranged inside the steel beam body, and steel beam positioning holes provided on both sides of the steel beam body.

[0005] Furthermore, each set of rectangular stiffening plates has steel beam connection holes inside, and the load-bearing beams have embedded buckles on both sides. By opening the steel beam connection holes, it is convenient to accurately connect the steel beams with other components, thereby enhancing the overall stability of the structure.

[0006] Furthermore, the upper and lower surfaces of the main steel beam are connected with steel beam stiffening plates, and corner stiffeners are connected at the four corners of the main steel beam. The steel beam stiffening plates and corner stiffeners effectively enhance the overall strength and deformation resistance of the main steel beam, improve its stability under complex stress environments, and extend its service life.

[0007] Furthermore, a steel column stiffening plate is connected to the inner wall of the lower end of the steel column body located on the clamping plate. The material of the steel column body is Q355B steel plate. Q355B steel plate has high strength and good toughness. The combination of the two makes the steel column connection more stable and less prone to deformation and damage.

[0008] Furthermore, the main body of the steel beam adopts an outward-folded edge, and the spacing between the stiffening plates of each group of steel columns is 75cm. The 75cm spacing is a reasonable distribution of the stiffening plates of the steel columns, which effectively improves the overall stability of the steel columns and ensures structural safety.

[0009] Furthermore, the position and size of the positioning hole body match the positioning holes of the steel beam body. Precise matching facilitates quick and accurate connection and installation of steel columns and steel beams, improves construction efficiency, and ensures structural installation accuracy and quality.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] In this invention, the steel column and beam bodies are bent after laser cutting and drilling holes in the steel plates. This not only enhances the material properties but also allows for the pre-reservation of functional round holes, making subsequent construction more efficient and convenient. The steel column body connection incorporates positioning slots on top of the traditional locking method, improving installation accuracy and enhancing bolt anti-slip performance. The steel beam body design incorporates more functional positioning holes and bends, resulting in greater structural stability, easier installation of secondary joists, and transformation from traditional single-sided load-bearing to double-sided load-bearing. In addition to these advantages, the steel beams also facilitate sill installation and better match doorposts, door beams, and connecting corridors. Attached Figure Description

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Examples, such as Figure 1 - Figure 10 As shown, this utility model provides a steel structure for an elevator shaft, including a steel column body 1, steel beam bodies 2 connected to both sides of the steel column body 1, load-bearing beams 3 connected to the front and rear ends of the steel column body 1, clamping plates 4 connected to the four corners of the inner wall of the steel column body 1, upper and lower concave-convex interlocking grooves 5 provided on the top of the steel column body 1, positioning holes 6 provided at the positions where the clamping plates 4 and the steel beam bodies 2 match, steel column connection holes 7 provided at the positions where the steel column body 1 and the steel beam bodies 2 match, four sets of rectangular stiffening plates 14 equidistantly arranged inside the steel beam bodies 2, and steel beam positioning holes 8 provided on both sides of the steel beam bodies 2.

[0026] like Figure 1 As shown, each rectangular stiffening plate 14 has steel beam connection holes 9 inside, and embedded buckles 10 are provided on both sides of the load-bearing beam 3. By opening the steel beam connection holes 9, it is convenient to accurately connect the steel beam with other components and enhance the overall stability of the structure.

[0027] like Figure 6 and Figure 7 As shown, steel beam stiffening plates 11 are connected to both the upper and lower surfaces of the main steel beam 2, and corner stiffeners 13 are connected to the four corners of the main steel beam 2. The steel beam stiffening plates 11 and corner stiffeners 13 can effectively enhance the overall strength and deformation resistance of the main steel beam 2, improve the stability of the main steel beam 2 under complex stress environments, and extend its service life.

[0028] like Figure 8 and Figure 9As shown, the steel column body 1 is connected to the inner wall of the lower end of the clamping plate 4 by a steel column stiffening plate 12. The material of the steel column body 1 is Q355B steel plate. Q355B steel plate has high strength and good toughness. The combination of the two makes the steel column connection more stable and less prone to deformation and damage.

[0029] like Figure 1 and Figure 9 As shown, the main body of the steel beam 2 adopts an outward-folded edge, and the spacing of the stiffening plates 12 of each group of steel columns is 75cm. The 75cm spacing is reasonably distributed to improve the overall stability of the steel columns and ensure structural safety.

[0030] like Figure 1 and Figure 6 As shown, the position and size of the positioning hole body 6 match the steel beam positioning hole 8 of the steel beam body 2. Precise matching facilitates quick and accurate connection and installation of the steel column and steel beam, improving construction efficiency and ensuring structural installation accuracy and quality.

[0031] The overall implementation achieves the following results: the improved steel structure offers significant advantages, with a more robust connection method and greatly enhanced structural stability. It also significantly strengthens the anti-slip performance of bolts, which was not effectively improved during pre-processing. This makes the installation of the external wall sub-keel efficient and convenient; the external wall sub-keel can be directly connected using self-drilled screws through pre-drilled holes in the steel column body 1 and steel beam body 2, eliminating the hassle of welding. The connection method of the steel column body 1 is also more stable, using an interlocking upper and lower concave-convex connection instead of the traditional planar connection, resulting in more precise positioning and greatly enhancing the force of the high-strength bolts. While most of the main load-bearing beams 3 previously used bolt connections, the structure was not strengthened, and the installation method could not completely eliminate the welding process. This improvement not only adds more high-strength bolt connections to the load-bearing beams 3, but the unique embedded snap-fit ​​10 connection also distributes more bolt shear force, resulting in superior load-bearing performance. At the door beams and sills, an outward-folding edge method is used to facilitate the installation of door columns and connecting corridor floor slabs, achieving a good connection using only self-drilled screws. In addition, this improvement is more economical in terms of material usage, saving at least 15% of the material compared to the general structure, making it more cost-effective.

[0032] Working principle: This improved scheme abandons the traditional square tube or H-shaped steel column in terms of the material of the main body of the steel column 1. It adopts Q355B steel plate, which is first laser-cut and drilled, then cut and shaped, and then bent. A steel column stiffening plate 12 is welded every 75cm, which makes the main body of the steel column 1 more stable and less prone to deformation when connected. The unique outward bending not only enhances the torsional performance of the main body of the steel column 1, but also allows the positioning hole 6 on the folded edge to accurately match the position of the positioning hole 8 on the steel beam.

[0033] The unique upper and lower concave-convex interlocking grooves 5 on the steel column 1 are not only more precise than the traditional direct docking method, but also greatly improve the strength by connecting the upper and lower steel columns with clamps 4 on the inner side.

[0034] Steel beam 2 also adopts an outward-folded edge, adding two outward-folded edges to the traditional C-shaped bend shape. This not only increases the strength of steel beam 2, but also, through the connection of steel beam connection hole 9 and steel column connection hole 7, as well as the connection of four sets of steel beam stiffening plates 11, the connection strength is far superior to that of general connection methods.

[0035] The addition of a rectangular stiffening plate 14 to the middle section of the main steel beam 2 not only increases the bending strength, but also provides a variety of secondary keel connection methods through the reserved double hole design. The secondary keel of the exterior wall can also be directly fixed by drilling self-drilling nails through the reserved small holes on the main steel beam and the main steel column.

[0036] The installation method of the load-bearing beam 3 is no longer the traditional welding method. The load-bearing beam 3 is lowered from above and connected by aligning the holes. The unique embedded buckle 10 will snap into the reserved slot on the steel column body 1. Tighten the corresponding screws. The load-bearing beam 3 and the steel column body 1 are not only directly connected by three screws at the front and rear, but can also be connected by stiffening plates and buckles. The quadruple connection is more secure and safer.

[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
