Description

Technical Field

[0001] The utility model relates to the field of building steel structures, in particular to a supporting beam for building steel structures. Background Art

[0002] Building steel structure refers to a building frame or support system made of steel. Steel structure can effectively bear the weight of the building, including floors, roofs and other loads. Steel structure has good seismic resistance and can provide higher safety in earthquakes. Compared with traditional building materials, steel structure can be constructed more lightly, thus achieving a larger internal space. Due to the characteristics of steel itself, building steel structure can remain stable for a long time and is not easily corroded or damaged. Steel structure can be recycled and reused, so it has advantages in environmental protection. Building steel structure is a widely used building material. It plays an important role in modern buildings, making buildings safer, more flexible, more durable and more environmentally friendly. The support beams in building steel structure are important structural elements used to support and reinforce buildings. These beams that span the building are usually located in the upper or middle part of the building to provide additional support and stability to ensure that the building has sufficient structural strength when subjected to loads such as wind pressure, earthquakes and other natural forces. Support beams are usually made of steel and are widely used in building structures due to their excellent tensile properties and strength.

[0003] After searching the existing Chinese patents: Announcement No., CN215631061U, a steel structure support beam for construction includes a support column, and the two ends of the support column are fixedly connected with a connecting column, and the outer surfaces of the two connecting columns are provided with external threads, and the outer surface of one of the connecting columns is fixedly connected to the support plate, and the outer surface of the other connecting column is fixedly connected to the bottom plate, and the middle of the outer surface of the support column is fixedly connected with a fixing groove, and one side of the outer surface of the fixing groove is provided with a plurality of first through holes. The advantage of this utility model is that through the threaded connection between the support column and the support plate, and the support column and the web, different sizes and shapes of support plates can be selected according to the different surfaces of the building to be supported, so that the fit is tighter. At the same time, the selection of the web not only increases the supporting force and the supporting area, but also limits the rotation of the support plate, ensuring the stability of the support, and the utility model has a simple structure and strong supporting force.

[0004] The above patent realizes the selection of support plates of different sizes and shapes according to the different surfaces of the building to be supported, so as to make the fit closer. At the same time, the selection of the web not only increases the supporting force and the supporting area, but also limits the rotation of the support plate, thereby ensuring the stability of the support. The utility model has a simple structure and strong supporting force. The height of the building steel structure at different positions is inconsistent. The height of the support column in the above patent is fixed. When in use, it cannot be adjusted according to actual conditions, resulting in a limited scope of use. In addition, the contact area between the support column and the web and the support plate is limited. There are many suspended positions at the bottom of the support plate. When the top of the support plate is subjected to uneven force, the support plate is prone to deformation, which affects the structural strength of the support plate.

[0005] Therefore, it is necessary to invent a support beam for building steel structure to solve the above problems. Utility Model Content
