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. And penetration of pipelines (such as fire fighting, heating and ventilation, electrical equipment pipe penetration and the like) in an all-indoor transformer substation is facilitated, and the floor height can be further reduced.
本发明公开了一种π型双腹板蜂窝梁及变电站，包括钢结构梁，所述钢结构梁设置有两个腹板，两个所述腹板对称分布于钢结构梁的内侧，其中，所述钢结构梁的截面高度为1000mm，截面宽度为500mm；所述腹板的截面高度为952mm，截面宽度为16mm；两个所述腹板之间的直线距离为328mm。该π型双腹板蜂窝梁及变电站，相较于500kVGIS层常规采用的H型钢梁，在承载力（截面模型Ix）大致相同的前提下，截面高度可由1400mm减少为1000mm，不会对楼层净高造成影响，通过在腹板2处开设蜂窝孔3，有利于全户内变电站内管道管线（如消防、暖通、电气设备穿管等）穿越，可进一步降低层高。
