Technical Field

[0001] The utility model relates to the technical field of suspension columns, in particular to a suspension column top reinforcement structure. Background Art

[0002] At present, suspension columns are mostly used to connect the main and secondary beams when the secondary beam is higher than the main beam, and are used as the connecting support and steel bar anchorage area of ​​the secondary beam.

[0003] However, during the use of the existing suspension columns, the existing suspension columns and the connecting plates are connected by welding, which makes the connection strength at the connection position between the existing suspension columns and the connecting plates low, so that long-term use may easily lead to open welding between the existing suspension columns and the connecting plates, thereby reducing the service life of the suspension columns. At the same time, during the use of the existing suspension columns, the existing suspension columns are usually an integrated structure and cannot be spliced, which results in a larger volume of the existing suspension columns. Special transportation equipment and suspension equipment are required during the transportation and handling of the suspension columns, thereby increasing the cost of transportation and handling.
