Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a concrete transfer beam node supporting a steel column and a building. Background Art

[0002] In modern construction projects, steel structures have obvious advantages in building assembly, industrialization, digitization, and greening. More and more superstructures are adopting steel structure systems, and their application scope is becoming increasingly wide.

[0003] Because underground buildings are in contact with soil, water, etc., and there are general concerns about corrosion and durability, cast-in-place reinforced concrete structures are usually used. This hybrid system of using a steel structure system for the upper structure and a cast-in-place reinforced concrete structure for the underground building is increasingly being used.

[0004] In actual engineering needs, due to differences in above-ground and underground usage functions, lane streamlines, etc., the steel columns of the above-ground structure are not extended to the basement, but are supported by the transfer beams of the basement top plate. In this way, the vertical loads, wind loads, and earthquake effects borne by the upper steel columns can be transmitted through the transfer beams. Therefore, the reliability of the nodes between the steel columns and the transfer beams is the guarantee of the safety of the upper structure.

[0005] In the existing technical solutions, the design of the node between the steel column and the transfer beam usually adopts a steel-concrete beam to support the steel column. The transfer beam contains steel and steel bars. The steel and steel bars collide with each other, which makes on-site construction difficult and the construction quality difficult to ensure. At the same time, the connection between the transfer column and the steel transfer beam at both ends also requires additional steel, which brings more inconvenience and increases the project cost.

[0006] In summary, the existing nodes between steel columns and transfer beams have technical defects such as complex structure, great construction difficulty, low construction efficiency, and high construction cost. The above defects seriously limit the further development of this field.

[0007] In view of this, the purpose of the utility model is to provide a new technical solution to solve the existing technical problems. Utility Model Content
