Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, specifically to a reinforced steel structure with steel structure joints. Background Technology

[0002] Steel structures are structural systems composed of steel materials. As one of the main types of building structures, their core components include steel beams, steel columns, and steel trusses made of shaped steel and steel plates. These components are connected by welds, bolts, or rivets. Due to their advantages of light weight and convenient construction, they are widely used in large factories, stadiums, and super high-rise buildings.

[0003] In the steel column assembly and splicing stage, to achieve precise positioning and safe erection, the traditional process typically involves the following steps: Ear plates are pre-welded to the outer perimeter of the upper and lower sections of the steel column to be assembled. A temporary fastening system is then formed using web plates and high-strength bolts. After the butt joint weld of the steel column is completed, the web plates must be removed sequentially, and the remaining ear plates must be cut off. While this process meets the construction accuracy requirements, the subsequent removal of the ear plates and cutting operations significantly increase the complexity of the process, not only extending the construction period but also potentially causing damage to the steel column base material due to the cutting operations. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a reinforced steel structure with steel structure joints, which eliminates the need to cut ear plates after the steel structure columns are connected.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reinforced steel structure with steel structure joints, comprising fixed columns and welded columns. The outer wall of the fixed columns is connected to two symmetrically arranged first U-shaped plates, and the outer wall of the welded columns is connected to two symmetrically arranged second U-shaped plates. Both ends of the first and second U-shaped plates are fixedly connected to fixing ears, and two first fastening bolts are threaded between each pair of opposite fixing ears. The outer walls of the two first U-shaped plates are fixedly connected to stiffening plates, and the stiffening plates are fastened to the outer walls of the second U-shaped plates by a fastening structure.

[0006] Furthermore, the fastening structure includes multiple sets of webs corresponding to the stiffeners, with two webs in each set, the top of each stiffener located between the two webs, and two second fastening bolts threaded onto the webs of each set.

[0007] Furthermore, a guide plate is fixedly connected to the top surface of each of the stiffeners.

[0008] Furthermore, each of the aforementioned stiffeners is provided with a clearance groove.

[0009] Furthermore, each of the ribs has a guide ball fixedly connected to the inner wall of the end near the guide plate.

[0010] Furthermore, compression pads are fixedly connected to the inner walls of both the first U-shaped plate and the second U-shaped plate.

[0011] Furthermore, the first U-shaped plate and the second U-shaped plate can also be provided as arc-shaped plates.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This utility model, through the coordinated assembly of the first U-shaped plate, the second U-shaped plate, and the stiffening plate, can stably connect the fixed column and the welding column, forming an integral structure and effectively improving the convenience of welding operations. After welding, only the first U-shaped plate and the second U-shaped plate need to be separated, without the need for additional cutting equipment, which greatly simplifies the operation process. The structure is simple, easy to operate, and highly practical. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] like Figures 1 to 4As shown, a reinforced steel structure with steel structure joints includes a fixed column 1 and a welded column 2. The outer wall of the fixed column 1 is connected to two symmetrically arranged first U-shaped plates 3, and the outer wall of the welded column 2 is connected to two symmetrically arranged second U-shaped plates 10. Both ends of the first U-shaped plates 3 and the second U-shaped plates 10 are fixedly connected to fixing ears 12. Each pair of opposite fixing ears 12 is threaded with two first fastening bolts 4. The outer walls of the two first U-shaped plates 3 are fixedly connected to stiffening plates 5, and the stiffening plates 5 are fastened to the outer walls of the second U-shaped plates 10 by a fastening structure.

[0021] like Figures 1 to 4 As shown, in the present invention, when the reinforced steel structure with steel structure connection is in use, after the fixed column 1 is fixed, the two first U-shaped plates 3 and the fixing ears 12 are connected to the outer wall of the fixed column 1 by the first fastening bolts 4. Before this, the stiffening plates 5 have been welded to the outer wall of the first U-shaped plates 3. When the first U-shaped plates 3 are fixed to the outer wall of the fixed column 1, the multiple stiffening plates 5 are just distributed on the periphery of the fixed column 1. Then, the second U-shaped plate 10 is fixed to the outer wall of the welded column 2, and the fixing ears 12 on the second U-shaped plate 10 are fastened by the multiple first fastening bolts 4 to ensure the stability of the second U-shaped plate 10 on the welded column 2.

[0022] When the welded column 2 is suspended from the fixed column 1 by the hoisting structure, the welded column 2 is positioned between multiple stiffening plates 5. As the welded column 2 descends and overlaps with the fixed column 1, the top of each stiffening plate 5 is connected to the fastening structure on the second U-shaped plate 10. At this time, the welded column 2 forms a whole through the stiffening plates 5, the fastening structure, and the second U-shaped plate 10 and the first U-shaped plate 3, so that the contact surface between the fixed column 1 and the welded column 2 can be welded.

[0023] By assembling the first U-shaped plate 3, the second U-shaped plate 10 and the stiffening plate 5 together, the fixed column 1 and the welded column 2 can be stably connected to form an integral structure, which effectively improves the convenience of welding operations. After welding is completed, only the first U-shaped plate 3 and the second U-shaped plate 10 need to be separated, without the need for additional cutting equipment, which greatly simplifies the operation process.

[0024] like Figure 2 and Figure 3 As shown, the fastening structure includes multiple sets of web plates 7 corresponding to stiffeners 5. Each set of web plates 7 consists of two sets, with the top of each stiffener 5 located between the two web plates 7. Each set of web plates 7 is threaded with two second fastening bolts 8.

[0025] Specifically, when the welded column 2 is suspended on the fixed column 1 and descends, the web plate 7 descends accordingly, so that the gap between the web plates 7 is inserted by the stiffening plate 5. Then, the web plate 7 and the stiffening plate 5 can be fastened by the second fastening bolt 8. At this time, the web plate 7, the stiffening plate 5, the first U-shaped plate 3 and the second U-shaped plate 10 form a whole.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, a guide plate 6 is fixedly connected to the top surface of each stiffener 5.

[0027] Specifically, when the welding column 2 is suspended, the guide plate 6 on the top of the multiple stiffeners 5 can guide the welding column 2. That is, as the welding column 2 descends, the lower end of the welding column 2 will contact the inclined side of the guide plate 6, thereby allowing the welding column 2 to enter the middle of the multiple stiffeners 5, so that the welding column 2 coincides with the top of the fixed column 1 after descending.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, each stiffener 5 is provided with a relief groove 11. The relief groove 11 allows the welding torch to weld on the stiffener 5. That is, when welding the connecting surface of two columns, the welding torch can weld on the position where the stiffener 5 is located through the relief groove 11, preventing the stiffener 5 from blocking the welding.

[0029] like Figure 2 and Figure 3 As shown, each stiffener 5 has a guide ball 13 fixedly connected to the inner wall of the end near the guide plate 6. When the welded column 2 descends and gradually overlaps with the fixed column 1, the guide ball 13 on the inner wall of the stiffener 5 will slide and connect with the outer wall of the second U-shaped plate 10. This setting can make the sliding smoother.

[0030] like Figure 2 and Figure 3 As shown, compression pads 9 are fixedly connected to the inner walls of both the first U-shaped plate 3 and the second U-shaped plate 10. The compression pads 9 make the first U-shaped plate 3 and the second U-shaped plate 10 more stable after they are snapped together.

[0031] like Figure 4 As shown, the first U-shaped plate 3 and the second U-shaped plate 10 can also be provided as an arc-shaped plate 14.

[0032] Specifically, since the columns are not only box-type columns but also cylindrical steel structure columns, the first U-shaped plate 3 and the second U-shaped plate 10 can also be set as arc-shaped plates 14. Thus, this structure can be used not only for box-type columns but also for cylindrical steel structure columns.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
