Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a prefabricated steel structure main and secondary beam connection structure. Background Art

[0002] Steel structure buildings are one of the building structures that my country explicitly requires to be vigorously developed. They can be divided into traditional steel structure buildings and prefabricated steel structure buildings. They have the advantages of mature structural design, convenient production, comprehensive construction measures, fast construction period, light weight, less waste emissions, and good durability. They have been widely used in the fields of industrial buildings and civil industrial buildings in my country. At the same time, steel structure buildings have lower carbon emissions than concrete buildings. In recent years, the technical research and development and project implementation of steel structures have become increasingly intense, and they have occupied an increasingly important position in my country's construction field.

[0003] In current steel structure buildings, the main form of connection between the main and secondary beams is that the web of the secondary beam extends out and is connected to the main beam stiffening rib by bolts. This connection method is hinged and can only bear shear force but not bending moment, which can easily lead to serious bending deformation or even damage of the building structure. For the entire building structure, this may affect the stability of the building, and in severe cases may even lead to the risk of structural collapse. Utility Model Content

[0009] By adopting the above technical solution, by opening corresponding first connecting holes and second connecting holes in the first connecting holes and the second connecting holes, the first connecting plate and the second connecting plate can be fixedly connected by a bolt structure.

[0010] Preferably, the nut is arranged on a side of the second connecting plate away from the first connecting plate.

[0011] By adopting the above technical solution, it is convenient for relevant personnel to install the nut on the screw rod from the side of the secondary beam away from the main beam, so that the nut can be installed more conveniently.

[0012] Preferably, the plurality of second connection holes are divided into two groups and are respectively arranged on both sides of the second connection plate, and the secondary beam web is arranged between the two groups of the second connection holes.

[0013] By adopting the above technical solution, a more uniform and stable force distribution can be achieved.

[0017] By adopting the above technical solution, the tightness of the fixed connection between the first connecting plate and the second connecting plate is further improved, thereby improving the ability of the building structure to bear bending moments.

[0018] Preferably, reinforcing ribs are provided on the main beam.

[0019] By adopting the above technical solution, the load-bearing capacity of the main beam can be improved by utilizing the reinforcing ribs, thereby enhancing the overall stability.

[0020] Preferably, the reinforcing rib and the first connecting plate are fixedly connected by welding.

[0021] By adopting the above technical solution, the tightness of the connection between the first connecting plate and the main beam is further improved.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: a second connecting plate is provided at the end of the secondary beam close to the main beam, and a first connecting plate is installed at the side of the main beam close to the first connecting plate. Subsequently, the two connecting plates are tightly connected together through a bolt structure or a welding process, thereby achieving a stable connection between the main beam and the secondary beam.

[0023] Compared with the traditional connection method, the structural design of the present application has significant advantages. It can not only effectively withstand shear force, but also has the ability to withstand a certain bending moment. Moreover, since the web plate and the upper and lower wing plates of the secondary beam remain intact, the bending and shear bearing capacity of the secondary beam ends are not affected, ensuring the overall strength and stability of the structure, thereby minimizing potential safety hazards and improving the reliability and safety of the structure.
