Problems solved by technology
[0002] At present, most of the connection nodes between the two beams and the supporting columns are fixed and connected together by bolts, but in the actual application process, the connection strength in the connection nodes is low. The main reason is that the steel column and the steel beam The adjacent edges can only be connected and fixed by bolts, which directly leads to poor overall tensile effect, and the installation is also very inconvenient, which is the biggest obstacle restricting the promotion of the current prefabricated steel frame structure buildings.

The invention discloses an assembled structure between a steel column and a steel beam on the top floor, which comprises two mutually butted steel beams (1), and the two steel beams (1) are welded and fixed into one body through beam sleeves (2) , the bottom of the beam cover (2) is provided with a steel column (3) docked with it; the inside of the steel column (3) is provided with a connecting device docked with the beam cover (2); the connecting device Contains a driving seat (4), the two ends of the driving seat (4) extend vertically out of the first guide rail (5), and the inner wall of the steel column (3) is provided with the first guide rail (5) arranged along its length direction. The first guide chute (6) of the guide rail (5) clearance sliding fit. The docking structure of the present invention is simple and convenient, because beams, columns, and beam sleeves can be docked not only from the edge of the joint, but also from the inside of the three, which greatly improves the connection and combination of beam-column nodes strength.
Description
technical field [0001] The invention relates to the field of assembled steel structures, in particular to an assembled connection structure between a top-floor steel column and two steel beams. Background technique [0002] At present, most of the connection nodes between the two beams and the supporting columns are fixed and connected together by bolts, but in the actual application process, the connection strength in the connection nodes is low. The main reason is that the steel column and the steel beam The adjacent edges can only be connected and fixed by bolts, which directly leads to poor overall tensile effect, and the installation is also very inconvenient, which is the biggest obstacle restricting the promotion of the current prefabricated steel frame structure buildings. Contents of the invention [0003] The object of the present invention is to provide a prefabricated structure between the steel column and the steel beam on the top floor, which can effectively ...
