The specific embodiment
To shown in Figure 6, stirrup 30, first adapter plate 10 and second adapter plate 20 wrap in present embodiment stirrup mechanism 1 as Fig. 1.This stirrup 30 is the solid elongated cylinder with first end 301 and second end 302, and first end 301 of this stirrup 30 is fixed on this first adapter plate 10, and second end 302 of this stirrup 30 is fixed on this second adapter plate 20.
The floor frame additional strengthening that present embodiment has stirrup comprises longeron 60 under longeron 40 under the left front floor, left back floor frame 50, the right front floor, right back floor frame 70 and two stirrup mechanisms 1.For one of them stirrup mechanism, first adapter plate 10 is fixed on by first bolt fastener that longeron 40, the second adapter plates 20 are fixed on the left back floor frame 50 by second bolt fastener under the left front floor.For the stirrup mechanism of opposite side, first adapter plate 10 is fixed under the right front floor on the longeron 60 by bolt fastener, and second adapter plate 20 is fixed on the right back floor frame 70 by bolt fastener.
For this stirrup because first, second upper surface 151,251 forms by two planes with definite angle X, make this first, second upper surface 151,251 can with the adaptive applying of cooresponding attachment face.Because first, second lower surface 152,252 convexes with first, second reinforced rib 17,27 respectively, not only can strengthen the intensity of first, second adapter plate 10,20, and be convenient to the carbon-dioxide arc welding technology of stirrup 30.Because the edge of first, second lower surface 152,252 bends out first, second flange 16,26, and first, second adapter plate 10,20 can be born bigger bending moment.This stirrup 30 is a solid, has increased the intensity of whole stirrup mechanism.
