Pi-shaped double-web honeycomb beam and transformer substation

The Pi-shaped double-web honeycomb beam comprises a steel structure beam, the steel structure beam is provided with two webs, the two webs are symmetrically distributed on the inner side of the steel structure beam, the height of the section of the steel structure beam is 1000 mm, and the width of the section of the steel structure beam is 500 mm; the height of the cross section of the web is 952 mm, and the width of the cross section of the web is 16 mm; the linear distance between the two web plates is 328 mm. According to the pi-shaped double-web honeycomb beam and the transformer substation, compared with an H-shaped steel beam conventionally adopted by a 500 kV GIS layer, on the premise that the bearing capacity (a section model Ix) is roughly the same, the section height can be reduced to 1000 mm from 1400 mm, the clear height of a floor cannot be affected, honeycomb holes 3 are formed in the webs 2, and therefore the bearing capacity of the H-shaped steel beam is greatly improved.
