As a preferred technical solution of the present invention, side is welded with side plate before and after the upper surface of the bottom girder, described
The medial extremity of side plate is connected with convex body transition.
As a preferred technical solution of the present invention, connecting pole, the footstock both sides are provided with the axis hole of the footstock
Connecting pole on be threaded with nut.
As a preferred technical solution of the present invention, backing plate is provided between adjacent two pieces of footstocks, in the connecting pole
Portion passes through the axis hole in the middle part of backing plate.
As a preferred technical solution of the present invention, the middle part of the convex body, which tilts, is carved with jack, the bearing plate
Upper end left and right side is relative to be welded with the plate that end is extended in jack, and the angle of the plate and bearing plate is 60 °.
As a preferred technical solution of the present invention, the lower end side of the bearing plate is fixed with floor, the floor
Upper surface be connected with the bottom surface transition of bottom plate.
Compared with prior art, the beneficial effects of the invention are as follows：This steel structure girder, simple in construction, stable connection, side plate exists
The height in bottom girder shearing face can be lifted in the case of reducing bottom girder weight, effectively improves the bend resistance ability of bottom girder, two pieces convex
The footstock of body connects by connecting pole with nut, and installation and removal are convenient, is provided with backing plate between adjacent footstock so that adjacent is convex
It can be steadily contacted between body and bottom girder, absorbability transmits caused vibrations inside bottom girder, is absorbed by bearing plate adjacent
Internal stress between bottom girder, and the scattered of internal stress is carried out by plate, bottom plate is connected with bottom girder by stud, cooperation is held
Pressing plate makes adjacent two foundation beam be connected as an entirety, and bottom girder junction caused by avoiding stress concentration is broken, and stability is strong,
Service life is grown.
