The purpose of the invention can be realized by the following technical scheme:

the utility model provides an optimization structural design of long span crossbeam of high rigidity, includes the roof beam body, gusset, side opening and trapezoidal boss, be fixed with the gusset on the both sides inner wall of the roof beam body, it has seted up the side opening to link up on one side of gusset, all be fixed with trapezoidal boss on the top both sides of the roof beam body, set up flutedly on the top outer wall of trapezoidal boss.

As a further scheme of the invention: a plurality of first round holes are formed in one side of the beam body in a penetrating mode, and a plurality of second round holes are formed in the two sides, located on the first round holes, of the beam body.

As a further scheme of the invention: and a guide rail is arranged on the other side of the beam body.

As a further scheme of the invention: the side hole is a circular through hole.

As a further scheme of the invention: the rib plates are formed by cross arrangement of equilateral triangles.

The invention has the beneficial effects that: the side holes arranged in the invention adopt circular through holes, so that the beam body has good ductility, meanwhile, the lightness of the beam body is increased, the arranged rib plates are formed by cross arrangement of equilateral triangles, compared with the prior common design in a shape like a Chinese character 'mi', transverse ribs without strengthening the strength are removed, the distance between the rib plates can be shortened greatly while the weight is kept, the strength of the beam body is increased, and the arranged trapezoidal bosses eliminate the condition of stress concentration at the connecting corners of the prior common square design, effectively reduce the deformation of the beam body and are worthy of wide application.
