Technical Field

[0001] The utility model relates to the technical field of construction engineering, and particularly relates to a connecting structure for a concrete column and a long-span beam body. Background Technique

[0002] Construction engineering is a part of construction projects, referring to the engineering entities formed by the construction of various building houses and their ancillary facilities and the installation activities of pipelines and equipment supporting them. Construction engineering includes factories, theaters, hotels, stores, schools, hospitals, and residences, etc., to meet the needs of people's production, residence, study, public activities, etc. Construction engineering has the unity of comprehensiveness, sociality, practicality, technology, economy, and architectural art. Compared with the scope of construction projects, the scope of construction engineering is relatively narrow, specifically referring to the installation projects of various building houses and their ancillary facilities and pipelines and equipment supporting them, so it is also called building construction engineering.

[0003] In construction engineering, the connection between concrete columns and beam bodies is the key to structural stability. At present, in the face of long-span beam bodies, conventional connection methods often lead to problems such as cracking and deformation at the connection parts due to complex forces and large loads, affecting the safety of the overall structure.

[0004] For example, a connection structure for a concrete column and an H-shaped steel beam disclosed in Chinese Patent (CN218814304U) includes a column cap and a connecting plate for connecting the column cap and the H-shaped steel beam; the column cap is hollow, a partition plate is provided on the column cap, and the partition plate is detachably connected to the H-shaped steel beam; reserved steel bars are provided at the top of the concrete column, and the concrete column is detachably connected to the column cap, and the reserved steel bars penetrate through the column cap. The utility model has the advantages of simple structure, convenient installation, time-saving and labor-saving, and realizes the rapid assembly between the concrete column and the H-shaped steel beam.

[0005] The above solution still has the following technical deficiencies. The above solution uses methods such as increasing connecting steel bars and using high-strength concrete to enhance the bearing capacity of the connection part. However, these methods often have high costs and large construction difficulties, and it is difficult to effectively solve the stress concentration problem at the connection between the long-span beam body and the concrete column. Based on this, a connecting structure for a concrete column and a long-span beam body is proposed. Content of the Utility Model

[0014] Furthermore, the fixing component includes a vertical plate abutted against the rear side of the cross beam, a plurality of second bolts fixed on the front side of the vertical plate, and a second nut threadedly connected to the outer surface of the second bolts.
