Abstract : Ordinary grid structure roof covering slabs(rein forced concrete covering slab of grid structure,out space covering slab of grid structure,fiber glass reinforced cement covering slab of grid structure)that e xt ensively used in grid structure roof are introduced in this paper.In the same ti me,the economical comparison to three kinds of grid structure covering slabs is worked according to analyzing the overall cost of grid structure roofing system. The economical span range applied in engineering is put forward.
Keywords : reinforced concrete covering slab of grid struct ure out space covering slab of grid structure fiber glass reinforced cement co vering slab of grid structure grid structure roofing system overall cost
