Accompanying drawing explanation
Fig. 1 is the structural representation of the lower support frame of the fascia board girder of prior art;
Fig. 2 is the structural representation of the lower support frame of fascia board girder of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
Refer to Fig. 2, the lower support frame of fascia board girder of the present invention, comprise epimere 1, stage casing 2 and hypomere 3, after connecting, form an integrally-built blanked part taken the shape of the letter U, wherein:
The both sides of the edge in stage casing 2 have a bit of lower flange 20 respectively as reinforced rib, make the cross-sectional plane in this stage casing 1 c-shaped; The surface in stage casing is offered one for lightening hole 21;
Epimere 1 comprises the front end that is smoothly connected in stage casing 2 and welded plate 11 before being connected to the upper end of epimere body 10 with the epimere body 10, that the angle in stage casing 2 is greater than 90 °, be connected to the wing-shaped plate 12 of 1 epimere body both sides for a pair and be connected to the side welded plate 13 of front end of a pair wing-shaped plate 12 for a pair; The surface of epimere body 10 is offered a rectangle lightening hole 14 and two circular lightening holes 15, the weight of lower support frame can be alleviated; The arc that front welded plate 11 is dug for opening upwards, radian and dashboard cross member are responsible for adaptation; The arc that side welded plate 13 is dug for outward opening, radian and dashboard cross member are responsible for adaptation;
