Description

Technical Field

[0001] The utility model relates to the field of connection between a steel pipe column and a main beam, in particular to a connection structure between a steel pipe column and a main beam. Background Art

[0002] In the construction of steel platforms, the traditional method is to cut a groove on the top of the steel pipe column and install the main beam directly in the groove. This method damages the integrity of the steel pipe column and changes the force transmission mode of the steel pipe column to a certain extent, and the groove concentrates the force. Cause: Slotting is convenient and saves trouble, and the two sides of the pipe wall after slotting are used to provide longitudinal constraints. Utility Model Content

[0003] Therefore, in order to solve the above-mentioned shortcomings, the utility model provides a steel pipe column and main beam connection structure, which realizes reliable and effective connection between the steel pipe column and the main beam without damaging the steel pipe column, makes the steel pipe column evenly stressed, and reduces the possibility of deformation of the steel pipe column caused by uneven stress.

[0004] The utility model is implemented by constructing a steel pipe column and main beam connection structure, which is characterized by:

[0005] Several sets of 400×200×20mm triangular steel plates are welded around the upper end of the column;
