One end, in front end, the side of boss is disposed with the first ladder boss and concave station, and described front end boss is convex with the first ladder
The upper top surface of platform at grade, on described front end boss on top surface, the first ladder boss top surface, concave station upper surface with
Front longitudinal or floor side member lower surface contact, and two side arms of bending buttress brace leading portion are provided with convex closure, per two neighboring convex
It is connecting groove between bag, top surface contacts with front longitudinal or floor side member side wall inner surfaces on described convex closure；
Described the second ladder boss, rear end boss are successively set on the upper surface of arc buttress brace back segment, and described
Top surface contacts with top surface on the boss of rear end with front longitudinal or floor side member lower surface on second ladder boss.
Used as a preferred embodiment of the present invention, described bending buttress brace leading portion is integrated into arc buttress brace back segment
Type structure, and reinforcement column is provided between.
Used as another kind of preferred version of the present invention, the bathtub construction of described inverted U groove, its depth of rebate adds along bending
Brutal leading portion to arc buttress brace back segment length direction diminishes.
Used as another preferred version of the present invention, described convex closure is highly between 3～5mm.
As another preferred version of the present invention, the two ends of described reinforcement girder construction upper surface be additionally provided with for
The location hole that front longitudinal or floor side member are fixed.
Used as another preferred version of the present invention, described reinforcement girder construction is connected to the notch of front longitudinal or floor side member
It is interior, to strengthen girder construction and be fixedly connected by solder joint with front longitudinal or floor side member contact site, solder joint is spaced 30～50mm.
As another preferred version of the present invention, described convex closure by upper top surface and be arranged on the left of upper top surface first
Side and the second side being arranged on the right side of top surface are surrounded.
Beneficial effects of the present invention and advantage are：The reinforcement girder construction, including with front end boss, the first ladder boss,
The bending buttress brace leading portion and the arc buttress brace back segment with the second ladder boss, rear end boss of concave station and convex closure, can make
Electrophoresis liquid is sufficiently flowed into, effectively antiseptic and rustproof；Push up on top surface, the first ladder boss on the front end boss of the reinforcement girder construction
Face, concave station upper surface contact with the inner top surface of front longitudinal or floor side member groove, top surface and front longitudinal or floor side member on convex closure
The medial surface of groove contacts, and top surface and top surface on the boss of rear end are interior with front longitudinal or floor side member groove on the second ladder boss
Top surface contacts, and this construction reduces buttress brace binding face quantity, facilitates workman to beat solder joint, man-hour is saved, while reducing car
Body abnormal sound, due to the increase in section, also improves car body distortion, the bending stiffness and buttress brace rigidity of structure of itself.
