Specific embodiment
This application provides a kind of connectionless board-like rectangular conduit girder connection attachment devices, for purpose, the skill for making the application
Art scheme and advantage are more clearly understood, below in conjunction with specific embodiment, and referring to attached drawing, further specifically to the application
It is bright.
Specific embodiment
A kind of connectionless board-like rectangular conduit girder connection attachment device, specifically: including rectangular tube steel column 1, convex plate
2, girder steel end plate 3, concave slot 4, girder steel haunched slab 5, bolt plate 6, which is characterized in that 1 outer wall of rectangular tube steel column
Weld the convex plate 2；The girder steel end plate 3 opens up the concave slot 4, the concave slot 4 and the convex plate
The connection of 2 clearance fits；The girder steel end plate 1 girder steel haunched slab 5 setting up and down；The bolt plate 6 and the girder steel end plate 3
Two sides fork ear connection.
Convex plate 2 with rectangular tube steel column 1 is made using 45 steel by quenching treatment, has good hardness
And wearability, four convex plates 2 are welded on 1 surrounding of rectangular tube steel column, convex plate 2 is equipped with the adverse slope mouth that gradient is 45 degree
