Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, and in particular to a stepped steel structure column with end plates for prefabricated buildings. Background Technology

[0002] In the modern construction industry, prefabricated buildings are gradually becoming a development trend due to their advantages such as high efficiency and environmental friendliness. A type of stepped steel structural column with end plates used in prefabricated buildings plays a crucial role in the structural support of these buildings. As a core supporting component, its performance directly affects the quality and safety of prefabricated buildings, and is of great significance to the overall stability and service life of the building. Therefore, it is a key area of ​​continuous research and innovation in the field of prefabricated building technology.

[0003] In existing prefabricated building technologies, vertical support columns are often connected using traditional methods such as welding and riveting. Welding fuses metal components together at high temperatures, using welding materials to fill gaps at high temperatures, and forming a strong connection after cooling. Riveting involves using rivets to pass through the components being connected, and by processing and deforming the ends of the rivets, the components are tightly connected together. These mechanical connection methods can achieve the connection of vertical support columns to a certain extent, but they each have their own operational procedures and characteristics based on their own technical principles.

[0004] However, these traditional methods of connecting vertical support columns have several problems. For example, the operation is extremely complex and requires highly skilled construction workers. During welding, precise control of parameters such as temperature, speed, and angle is crucial; otherwise, welding defects are likely to occur. Similarly, precise positioning of the rivets and control of the riveting force during riveting also require extensive experience. This results in a significant investment of manpower and time, and the connection accuracy is difficult to guarantee. Since errors in manual operation are unavoidable, deviations often occur when vertical support columns are joined, making it difficult to evenly distribute loads under stress, leading to structural instability, significant safety hazards, and impacting the quality and safety of prefabricated buildings. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an end plate stepped steel structure column for prefabricated buildings, which aims to improve the problems caused by the fact that the connection method of vertical support columns in traditional prefabricated buildings is often complicated, requires a lot of manpower and time, and the connection accuracy is difficult to guarantee, which easily leads to docking deviation and structural instability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel structure column for end plate steps in prefabricated buildings, including a first vertical support column, a second vertical support column provided on the upper surface of the first vertical support column, a transverse support column provided on one side of the outer wall of the first vertical support column, a connecting component provided at one end of the first vertical support column, and reinforcing components provided on the outer walls of both the first vertical support column and the second vertical support column;

[0007] The connecting assembly includes a second connecting plate. The lower surface of the second connecting plate is fixedly connected to one end of a vertical support column. One end of the second vertical support column is fixedly connected to the first connecting plate. An L-shaped fixing groove is provided on the lower side of the inner side of the first connecting plate. A threaded rod is rotatably connected to the inner wall of the second connecting plate. A rotating wheel is fixedly connected to one end of the threaded rod. A movable ring is threadedly connected to the outer wall of the threaded rod. An L-shaped fixing plate is fixedly connected to the outer wall of the movable ring. A guide rod is slidably connected to the inner wall of the movable ring. A fixing screw is threadedly connected to the inner wall of the first connecting plate.

[0008] Furthermore, the reinforcing component includes an L-shaped reinforcing member, which is disposed on the outer wall of vertical support column one and vertical support column two. The outer wall of vertical support column one and vertical support column two is provided with a mortise. The inner wall of the mortise is provided with a sliding groove and a tenon. A fixing rod is threadedly connected to the inner wall of the tenon. One end of the fixing rod is fixedly connected to a rotating wheel two.

[0009] Furthermore, the outer wall of the tenon is slidably connected inside the groove, and the mortise and tenon are used to strengthen the support of the first vertical support column, the second horizontal support column, and the third vertical support column.

[0010] Furthermore, the L-shaped reinforcing members are all disposed on the outer walls of the mortise and tenon, and the L-shaped reinforcing members are used to strengthen the support of the mortise and tenon.

[0011] Furthermore, the outer wall of the vertical support column is positioned between the mortise and tenon.

[0012] Furthermore, the outer wall of the fixing rod is threadedly connected to the inner wall of the tenon, and the fixing rod is used to fix the mortise and tenon together.

[0013] Furthermore, the outer wall of the fixing screw is threaded onto the inner wall of the second connecting plate, and the fixing screw is used to fix the first connecting plate to the second connecting plate.

[0014] Furthermore, the outer wall of the L-shaped fixing plate is slidably connected to the inside of the L-shaped fixing groove, and the L-shaped fixing plate is used to limit the connection between the first connecting plate and the second connecting plate.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, when connecting vertical support column one and vertical support column two, rotating wheel one drives the threaded rod to rotate, allowing the moving ring to move along the guide rod, so that the L-shaped fixing plate is inserted into the L-shaped fixing groove, and then the fixing screw is tightened to complete the connection. This solves the problems that traditional connection methods for vertical support columns in prefabricated buildings are often complicated to operate, require a lot of manpower and time, and have difficulty in ensuring connection accuracy, which can easily lead to docking deviations and structural instability. This invention achieves rapid connection, reduces construction difficulty and labor costs, and improves construction efficiency. Through threaded transmission and limiting structure, it ensures accurate docking of vertical support columns one and two, has strong connection stability, and improves the overall quality and safety of prefabricated building structures.

[0017] 2. In this utility model, mortises and tenons are installed on the outer walls of vertical support columns one and two, allowing the tenons to slide and be positioned within the mortise grooves. The rotating wheel two is used to tighten the fixing rod, and L-shaped reinforcing members are installed to strengthen the support. This achieves the cooperation between the mortise and tenon structure and the fixing rod, dispersing the force on the column and improving the overall load-bearing capacity of the structure. The L-shaped reinforcing members further strengthen the mortises and tenons, improving the stability and reliability of the steel structure column and extending the service life of the prefabricated building.

An L-shaped fixing groove 12 is opened on the lower side of the inner side of the first connecting plate 5. A threaded rod 8 is rotatably connected to the inner wall of the second connecting plate 6. Under the drive of the first rotating wheel 7, the threaded rod 8 cooperates with the moving ring 9 to convert the rotational motion into the linear motion of the moving ring 9, thereby adjusting the position of the L-shaped fixing plate 10. One end of the threaded rod 8 is fixedly connected to the first rotating wheel 7. The outer wall of the threaded rod 8 is threadedly connected to the moving ring 9. The outer wall of the moving ring 9 is fixedly connected to the L-shaped fixing plate 10.

A guide rod 11 is slidably connected to the inner wall of the moving ring 9. A fixing screw 13 is threadedly connected to the inner wall of the first connecting plate 5.

[0028] Specifically, when connecting vertical support column 1 and vertical support column 4, rotate wheel 7 to rotate threaded rod 8, which drives moving ring 9 to move along threaded rod 8 under the restriction of guide rod 11, thereby pushing L-shaped fixing plate 10 into L-shaped fixing groove 12 of connecting plate 5. Finally, use fixing screw 13 to tightly connect connecting plate 5 and connecting plate 6.

[0029] Reference Figure 1 - Figure 5The reinforcing component includes an L-shaped reinforcing member 14, which is disposed on the outer wall of vertical support column 1 and vertical support column 2. A mortise 15 is provided on the outer wall of vertical support column 1 and vertical support column 2. A groove 17 is formed on the inner wall of the mortise 15, and a tenon 16 is provided on the inner wall of the mortise 15. The two form a mortise and tenon structure. Vertical support column 1 is located between them. The tenon 16 slides within the groove 17 of the mortise 15. Its position can be adjusted to better adapt to different installation requirements. A fixing rod 2 is threadedly connected to the inner wall of the tenon 16. One end of the fixing rod 2 is fixedly connected to a rotating wheel 18. The outer wall of the tenon 16 is slidably connected inside the groove 17. The mortise 15 and the tenon 16 are used to reinforce the vertical support. The support of column 1, horizontal support column 3 and vertical support column 4, and the L-shaped reinforcing member 14 are all set on the outer wall of mortise 15 and tenon 16. The L-shaped reinforcing member 14 is used to strengthen the support of mortise 15 and tenon 16. The outer wall of vertical support column 1 is set between mortise 15 and tenon 16. The outer wall of fixing rod 2 is threaded to the inner wall of tenon 16. Fixing rod 2 is used to fix mortise 15 and tenon 16. The outer wall of fixing screw 13 is threaded to the inner wall of connecting plate 2 6. Fixing screw 13 is used to fix connecting plate 1 5 and connecting plate 2 6. The outer wall of L-shaped fixing plate 10 is slidably connected to the inside of L-shaped fixing groove 12. L-shaped fixing plate 10 is used to limit the position of connecting plate 1 5 and connecting plate 2 6.

[0030] Specifically, mortises 15 and tenons 16 are installed on the outer walls of vertical support column 1 and vertical support column 4, so that tenons 16 can slide and adjust their position in the groove 17 of mortises 15 to form a mortise and tenon structure. Then, the rotating wheel 2 18 is rotated to drive the fixing rod 2 to tighten and fix mortises 15 and tenons 16. Finally, L-shaped reinforcing members 14 are installed on the outside.

[0031] Working principle: When a steel structure column with stepped end plate is needed for prefabricated buildings, and when it is necessary to connect vertical support column 1 and vertical support column 4, firstly, by rotating wheel 7, the threaded rod 8 is driven to rotate. The threaded rod 8 drives the moving ring 9 to move. The moving ring 9 slides on the surface of the guide rod 11. The guide rod 11 restricts the rotation of the moving ring 9, so that the moving ring 9 can only move along the direction of the guide rod 11 on the threaded rod 8. When the moving ring 9 moves, it drives the L-shaped fixing plate 10 to move. The L-shaped fixing plate 10 is inserted into the L-shaped fixing groove 12 inside the connecting plate 5. After it is inserted into place, the fixing screw 13 is screwed into the connecting plate 6 to make it tightly connected with the connecting plate 5, thereby realizing the connection between vertical support column 1 and vertical support column 4.

[0032] In addition, mortises 15 and tenons 16 are installed on the outer walls of vertical support column 1 and vertical support column 4. Vertical support column 1 is located between mortises 15 and tenons 16. Tenons 16 slide in the groove 17 inside mortises 15 to form a mortise and tenon structure, which is used to strengthen the support of vertical support column 1, horizontal support column 3 and vertical support column 4. Rotating wheel 2 18 drives the fixed rod 2 to rotate. When the fixed rod 2 rotates, it will gradually tighten, fixing mortises 15 and tenons 16 together. L-shaped reinforcing members 14 are installed on the outside of mortises 15 and tenons 16 to further strengthen the support effect of mortises 15 and tenons 16 and improve the stability of the entire steel structure column.
