The specific embodiment
The utility model relates to a kind of girder steel post member and according to the steel roof truss of this girder steel post member, below in conjunction with accompanying drawing, feature of the present utility model is elaborated:
With reference to Fig. 2,3, the first kind of described girder steel post of specific embodiment member 100 of the present utility model comprises T type upper chord 101, T type lower chord 102, and be evenly distributed in T type upper chord 101 and 102 of T type lower chords and the paired a plurality of web members 103 that are provided with.With reference to Fig. 4, described web member 103 comprises body part 131, is positioned at first connecting portion 132 that is fixed on upper chord at body two ends and is fixed on second connecting portion 133 of lower chord.
Wherein, T type upper chord 101, T type lower chord 102 can be formed by connecting dorsad by two angle steel respectively.T type upper chord 101 sharp T type lower chords 102 are oppositely arranged, the centre is connected by bolt or riveting bolt to web member 103 by the some of even setting, the body part 131 of web member 103 has hollow bulb to reduce flexural stress, and width has variation and concentrates to reduce stress.First connecting portion 132 and second connecting portion 133 are provided with connecting hole.
