The concave side and crossbeam button corresponding position for stating I-steel main body, which are provided with, installs plate additional, the intermediate plate both sides of the I-steel main body
Rib is provided with face.
As a kind of preferred embodiment of the present utility model, the rib is in continuous V-shape arranged, the rib
Section be semicircle, the rib interlaced arrangement of the I-steel main body intermediate plate both sides, the rib and I-steel main body are welded
Connect in succession.
As a kind of preferred embodiment of the present utility model, first gusset is welded on I-steel main body at equal intervals
On on the inside of concave surface, distance is 1.3m~1.8m between two neighboring first gusset..
As a kind of preferred embodiment of the present utility model, the plate that installs additional is welded on I-steel in C font structures
On the inner concave of main body, reinforcing plate is welded with the middle part of the inner concave for installing plate additional.
As a kind of preferred embodiment of the present utility model, the crossbeam button is symmetrical C fonts steel plate, and openings
To opposite.
The beneficial effect that the utility model is reached is：Pass through equidistant welding bar plate, phase on the inner concave of I-steel
When in reducing draw ratio, adding the bending resistance of I-steel main body, stability, the rib of I-steel main body two sides are improved
The tensile strength and crush resistance strength of bending place are strengthened, crossbeam its own mechanical performance is improved, in crossbeam button corresponding position
Plate and reinforcing plate are installed in setting additional, are increased the thickness at the maximum load of I-steel main body, are improved the bend resistance ability at this, overall
Structure increases body of a bridge structural strength, reduces deformation quantity, keeps the stability of steel bridge in itself, so that the stress to junction is reduced,
Increase service life.
