Abstract
Description
Technical Field
[0001] This utility model relates to a connection structure suitable for multi-layer steel bars and steel columns, belonging to the field of building construction technology. Background Technology
[0002] Currently, steel structure buildings are increasingly used in the construction industry due to their numerous advantages, such as high strength, light weight, good seismic performance, and fast construction speed. However, in basement structural design, considering the characteristics of concrete structures in terms of durability, fire resistance, and cost, basements typically still use concrete structures. When a steel structure building is connected to a basement concrete structure, a transfer member is often required on the first basement level to achieve effective force transfer and a smooth transition between the upper steel structure and the lower concrete structure. This process inevitably involves the connection between the longitudinal reinforcement of the beams and the stiffened steel columns.
[0003] Current construction practices only provide construction methods for situations where the top and bottom layers of steel reinforcement in a concrete beam encounter stiffened steel columns. However, in engineering practice, due to the diversity of building functions and the complexity of structural design, complex construction situations often arise where the top and bottom of a concrete beam have two or even more layers of steel reinforcement that simultaneously encounter stiffened steel columns.
[0004] If traditional construction techniques are still used under these circumstances, such as using multi-layered connecting plates with gradually increasing lengths to lap the reinforcing bars, problems such as collisions between the column longitudinal reinforcement and the lap plate, interference between the column stirrups and the web of the steel support, and contact between the wall vertical distribution reinforcement and the lap plate will occur. These collision and interference problems will not only seriously affect the installation quality and connection reliability of the reinforcing bars, but also significantly increase the difficulty of on-site construction, leading to adverse consequences such as low construction efficiency, extended construction period, and increased costs. Therefore, improvements are urgently needed. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art, this utility model designs a connection structure suitable for multi-layer steel bars and steel columns. When two layers of steel bars are lapped, the stress at the connection node can be distributed relatively evenly, reducing the occurrence of stress concentration and improving the durability and reliability of the connection node.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A connection structure suitable for multi-layer steel reinforcement and steel columns includes a connecting column vertically fixed to the side of the steel column body. The connecting column includes a vertically arranged web and flanges horizontally fixed to the upper and lower ends of the web. Several pairs of perforated ribs are symmetrically arranged on both sides of the web. Multiple insertion holes are arranged in a downward array on the perforated ribs. A perforated panel is fixedly connected to the free end of the connecting column. Multiple insertion holes are also arranged in a downward array on the perforated panel.
[0007] Furthermore, the perforated rib plate is provided with five layers of two insertion holes in each layer.
[0008] Furthermore, the upper and lower ends of the perforated rib are respectively fixedly connected to two flange plates.
[0009] Furthermore, the perforated panel is fixedly connected to the two flange plates and the web plate.
[0010] Furthermore, the perforated panel is provided with five layers of four insertion holes in each layer.
[0011] Compared with the prior art, this utility model has the following features and beneficial effects: This utility model forms a strong and rigid node domain through the rigid connection of the flange plate and web plate, and multiple fixations between the upper and lower ends of the perforated rib plate and the flange plate, and between the perforated panel plate and the flange plate and web plate. This domain can effectively resist bending moment and shear force caused by load, ensuring the connection strength and stability between the structure and the steel column. At the same time, through the multi-layer insertion design of the perforated rib plate and perforated panel plate, a clear and predetermined connection path is provided for the upper and lower layers of steel bars in the concrete beam, effectively avoiding spatial interference with other components such as column longitudinal bars and stirrups, ensuring the quality of steel bar installation and connection reliability, and significantly improving construction efficiency.

[0014] The present invention will now be described in more detail with reference to the embodiments.
[0015] Please see Figures 1-4 This embodiment is applicable to the connection structure of multi-layer steel bars and steel columns, including a connecting column that is vertically fixed to the side of the steel column body 1.
[0016] Specifically, the connecting column includes a vertically arranged web plate 5 and horizontally fixed flange plates 2 at the upper and lower ends of the web plate 5.
[0017] In this embodiment, a pair of perforated ribs 4 are symmetrically arranged on both sides of the web plate 5. The perforated ribs 4 have multiple layers of insertion holes 7 arranged in an array from top to bottom. In this embodiment, the perforated ribs 4 are located in the middle of the web plate 5, which provides better stability.
[0018] The free end of the connecting column is fixedly connected to a perforated panel 3, and the perforated panel 3 is also provided with multiple layers of insertion holes arranged in a downward array.
[0019] To ensure that the reinforcing bars 6 are inserted neatly in layers, the perforated rib plate 4 is provided with five layers of two insertion holes 7 in each layer, and the perforated panel 3 is provided with five layers of four insertion holes 7 in each layer. The insertion holes 7 on the perforated rib plate 4 and the insertion holes 7 on the perforated panel 3 correspond one-to-one.
[0020] Furthermore, the upper and lower ends of the perforated rib plate 4 are fixedly connected to the two flange plates 2 respectively, making the connection more stable and the overall integrity stronger.
[0021] Furthermore, the perforated panel 3 is fixedly connected to the two flange plates 2 and the web plate 5, making the connection more stable and the overall integrity stronger.
[0022] The working principle of this utility model is as follows: During installation, as needed, the multi-layer horizontally arranged steel bars 6 are inserted from their ends into the corresponding insertion holes 7. The steel bars 6 need to pass through the four insertion holes 7 on the same layer of the hole panel 3 and the two corresponding insertion holes 7 on the same layer of the hole ribs 4 on both sides at the same time. Then, the ends of the steel bars 6 are welded to the steel column body 1 to complete the installation.
