[0001] This utility model relates to the field of steel structure connection technology, specifically a steel structure connection and fixing device. Background Technology

[0002] Steel structure connection refers to the technical means by which mechanical force transmission and spatial fixation are achieved between steel structure components (such as beams, columns, supports, etc.) or parts through specific structures, usually by welding or bolting.

[0003] A search revealed a Chinese patent (CN216892828U) disclosing a steel structure connection and fixing device, comprising vertically connected vertical steel sections and horizontal steel sections. The upper ends of the horizontal steel sections are connected to the vertical steel sections via tie members on both sides, and the tie members on both sides are connected by clamping bolts. The tie members are clamped on the outside of the vertical steel sections. The lower end of the horizontal steel sections is connected to the vertical steel sections via support members. The support members, horizontal steel sections, and tie members are connected by positioning bolts. The vertical connection and fixing between the steel sections is achieved through the tie members and support members, which not only reduces the number of holes to be made in the steel sections and improves the structural strength of the steel sections, but also increases the connection area between the steel sections and the vertical steel sections. The horizontal steel sections are firmly fixed by a circumferential gripping method, and the connection between the tie members and support members and the vertical steel sections is simple and reliable, improving the overall strength and stability, and making the steel structure connection more reliable and safe.

[0004] However, in actual use, it was found that the above-mentioned patent requires the use of a crane or gantry crane to lift and assemble the transverse steel sections. During the assembly process, it is easily affected by the environment or manual operation, making it difficult to keep the transverse steel sections stable and increasing the difficulty of steel structure connection. Therefore, we propose a steel structure connection and fixing device. Utility Model Content

[0005] The technical problem to be solved by this application is that the above-mentioned patent requires the use of a crane or gantry crane to lift the transverse steel before it can be assembled. During the assembly process, it is easily affected by the environment or manual operation, making it difficult to keep the transverse steel stable and increasing the difficulty of steel structure connection.

[0006] To solve the above-mentioned technical problems, this application provides a steel structure connection and fixing device, including vertical steel and horizontal steel. The upper and lower ends of one end of the horizontal steel are welded with hanging rods. Positioning plates are provided on both sides of the vertical steel. The positioning plates are respectively provided with upper grooves and lower grooves adapted to the size of the hanging rods. The upper groove is U-shaped and the lower groove is hook-shaped.

[0007] In some embodiments, the positioning plate is formed by welding a first connecting plate and a second connecting plate to form an integral structure. The positioning plate is L-shaped, with the first connecting plate attached to the outer side of the vertical steel section and the second connecting plate attached to one end of the horizontal steel section.

[0008] In some embodiments, purlin supports are placed at both the top and bottom of the transverse steel section.

[0009] In some embodiments, threaded holes are provided on the purlin bracket, the first connecting plate, the vertical steel section and the horizontal steel section, and positioning bolts are threaded into the threaded holes, with positioning nuts fitted on the outer threads of the positioning bolts.

[0010] In some embodiments, both the upper and lower grooves have arc-shaped surfaces at their edges.

[0011] In some embodiments, the hanging rod, the first connecting plate, and the second connecting plate are all made of reinforcing ribs.

[0012] This utility model has at least the following beneficial effects:

[0013] After the positioning plate is assembled on the vertical steel section and the hanging rod is welded on the horizontal steel section, the hanging rod is hung in the upper and lower grooves of the positioning plate, which can stabilize the horizontal steel section and solve the problem of the horizontal steel section being difficult to keep stable during the assembly process.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to Figure 1 and Figure 2 This utility model provides a technical solution: a steel structure connection and fixing device, including a vertical steel section 1 and a horizontal steel section 3. A hanging rod 4 is welded to the upper and lower ends of one end of the horizontal steel section 3. A positioning plate 2 is provided on both sides of the vertical steel section 1. An upper groove 5 and a lower groove 6 adapted to the size of the hanging rod 4 are respectively opened on the positioning plate 2. The upper groove 5 is U-shaped and the lower groove 6 is hook-shaped.

[0022] The design of the upper groove 5 and the lower groove 6 provides vertical positioning constraints for the hanging rod 4 on the transverse steel 3, restricting the horizontal displacement of the transverse steel 3. Compared with the design of drilling holes in the vertical steel 1 to insert the transverse steel 3, the design of positioning plate 2 and hanging rod 4 does not damage the overall structure, avoids the local strength reduction caused by drilling, and increases the strength and stability of the overall structure. When maintenance and replacement of parts are required, disassembly and reinstallation can be more convenient.

[0023] Example 2: Based on Example 1, such as Figure 2 As shown, the positioning plate 2 is formed by welding the first connecting plate 201 and the second connecting plate 202 into an integral structure. The positioning plate 2 is L-shaped. The first connecting plate 201 is attached to the outer side of the vertical steel 1, and the second connecting plate 202 is attached to one end of the horizontal steel 3.

[0024] The integrated structural design ensures the overall stability of the positioning plate 2 and meets the connection requirements of the angle. The L-shaped design enables a stable connection between the positioning plate 2 and the vertical steel 1 and the horizontal steel 3.

[0025] Example 3: Based on Example 2, such as Figure 3 As shown, purlin supports 7 are placed at both the top and bottom of the transverse steel section 3.

[0026] The purlin 7 is an existing structure, with an L-shaped inner side welded with a right-angled triangle. It is attached to the connection between the vertical steel 1 and the horizontal steel 3 to support the horizontal steel 3 and enhance its stability.

[0027] Example 4: Based on Example 3, such as Figure 4 and Figure 5As shown, threaded holes 8 are provided on the purlin bracket 7, the first connecting plate 201, the vertical steel 1 and the horizontal steel 3. Each threaded hole 8 is threaded with a positioning bolt 9, and a positioning nut is threaded on the outer side of the positioning bolt 9.

[0028] The threaded hole 8 allows the positioning bolt 9 to be inserted into the threaded hole 8, which, together with the positioning nut, secures the purlin support 7, the first connecting plate 201, the vertical steel 1, and the horizontal steel 3.

[0029] Example 5: Based on Example 4, such as Figure 2 and Figure 5 As shown, both the upper groove 5 and the lower groove 6 have arc-shaped surfaces at their edges. These arc-shaped surfaces reduce the frictional resistance between the upper groove 5 and the lower groove 6 and the hanging rod 4. Under stress, they can reduce stress concentration and thus improve the durability of the second connecting plate 202.

[0030] Example 6: Based on Example 5, such as Figure 1 and Figure 2 As shown, the hanging rod 4, the first connecting plate 201, and the second connecting plate 202 are all made of reinforcing ribs. Reinforcing ribs typically have high strength and rigidity, which can significantly improve the load-bearing capacity and stability of the entire connection and fixing device, making it more suitable for high-load environments. The addition of materials is to ensure that the hanging rod 4, the first connecting plate 201, and the second connecting plate 202 meet high load-bearing requirements.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
