Large-span prestressed concrete filled steel tube slab and frame combined structure garage slab
The invention relates to a large-span prestressed concrete filled steel tube slab and frame combined structure garage slab. A combined component uses steel used in a prestressed beam slab as a lower part tensioned component and uses high-strength concrete filled steel tubes at middle and upper parts of a corresponding rib as a compression bearing component for simultaneously forming a slab-frame stressed structure component. The garage slab is characterized in that a stress mode of mainly bearing the bending stress of the prestressed beam slab is changed, so that the cross section height can be greatly reduced. Meanwhile, the compression bearing capacity of an upper part concrete filled steel tube chord rod is improved by 3 to 4 times through being compared with that of ordinary concrete, so that an arch chord rod can use the smaller cross section, and the self weight of the structure and the engineering manufacturing cost can be further and correspondingly reduced.
