Examples

Referring to the drawings in the specification and as shown in fig. 1-5, a bending truss according to the present application comprises:

the number of the main beams 1 is at least two. The girder 1 is bent along the surface, and the girder 1 comprises a plurality of bending box bodies 11 which are spliced in sequence, and the shapes of the bending box bodies 11 are different. Bending means that all cross-sectional center points of the bending torsion box 11 remain on the same plane. Torsion means that all cross-sectional center points of the bent torsion box 11 are not on the same plane. As shown in fig. 2, the main beam 1 is bent in a rightward direction, and the height of the turn box 11 constituting the main beam 1 is different. The bending box 11 includes an upper wing plate 111, a lower wing plate 112, and two side webs 113 connected in sequence, and at least one of the upper wing plate 111, the lower wing plate 112, and the webs 113 is a bending plate. The upper wing plates 111 of the adjacent bending box bodies 11 are different in bending degree, the lower wing plates 112 of the adjacent bending box bodies 11 are different in bending degree, and the web plates 113 of the adjacent bending box bodies 11 are different in bending degree, so that the different shapes of the bending box bodies 11 are realized. In the modeling process, the coordinates of the bending truss shown in fig. 5 are expressed as follows by setting a space coordinate system:

therefore, the shapes of the adjacent bending box bodies in all directions are changed, and the bending box bodies with different shapes are welded into the main girder 1 of the bending truss, so that the bending truss has more shape changes. Based on this, in the splicing process of the bending box 11, the upper wing plate 111, the lower wing plate 112 and the web 113 are all subjected to bending deformation by the bending device so as to reach the preset bending degree. In addition, the inside of the bending box 11 is provided with a partition plate, the partition plate is attached to the inner wall surface of the bending box 11, and the shape of the partition plate changes with the cross-sectional shape of the main beam 1.

The bending truss further comprises a plurality of secondary beams 2, wherein the plurality of secondary beams 2 are connected between two adjacent main beams 1. The end face of the secondary beam 2 is perpendicular to the surface of the main beam 1 connected with the secondary beam 2, namely, the secondary beam 2 generates bending torsion along with the bending torsion of the main beam 1. The secondary beam 2 is internally provided with a baffle plate.

The application has the advantages that:

The present utility model is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present utility model are intended to be included in the scope of the present utility model.
