Abstract

The invention provides a concrete column and steel beam connecting structure, and belongs to the technical field of building structures. The connecting structure comprises a concrete column, a connecting mechanism and a steel beam, the connecting mechanism sleeves the outer side of the concrete column, the steel beam is fixedly connected with the connecting mechanism, the connecting mechanism comprises two connecting end plates symmetrically wrapping the outer side of the concrete column, a gap exists between the connecting end plates and the concrete column, and a grouting layer is poured in the gap; two outer ring plates are vertically and symmetrically arranged on the outer side surface of the connecting end plate, connecting rib plates are evenly arranged between the two outer ring plates at intervals, a steel beam web in the steel beam is fixedly connected with the connecting rib plates through connecting plates, and the connecting plates are fixedly connected with the steel beam web and the connecting rib plates through connecting bolts. The structural strength of connection of the steel beam and the concrete column is effectively improved.

Description

technical field [0001] The invention relates to a connection structure between a concrete column and a steel beam, and belongs to the technical field of building structures. Background technique [0002] The frame node is the key to connect the frame beam and the frame column, and the connection node should have sufficient bearing capacity, stiffness and ductility. In the reconstruction and expansion project of the existing reinforced concrete frame structure, the new part adopts the steel structure scheme, which has many advantages such as small load increase, avoidance of wet work, and fast construction speed. Therefore, it is of great significance to study the connection structure and construction technology of suitable new steel beams and existing reinforced concrete columns. [0003] At present, the existing connection structure between the newly added steel beam and the reinforced concrete column mainly adopts the end plate, and the end plate is connected with the con...
