Cast-in-place outdoor step member and method of decreasing differential settlement between outdoor step member and main building
The invention discloses a cast-in-place reinforced concrete outdoor step member, comprising a cast-in-place reinforced concrete outdoor step and further comprising an upper support and a lower support both disposed on a main building. Upper and lower portions of the back of the reinforced concrete outdoor step are provided with upper and lower step connectors, respectively. The cast-in-place reinforced concrete outdoor step member further comprises a concrete leveling cushion layer and PVC (polyvinyl chloride) pipe piles or PP-R (polypropylene random) pipe piles. Further disclosed is a method of decreasing differential settlement between the cast-in-place reinforced concrete outdoor step member and the main building. The rigidity and strength of the outdoor reinforced concrete step member are improved; materials of a pile foundation are obtained in situ, the cost is low, rusting is rare; the differential settlement between the outdoor step member and the main building is effectively controlled and is reduced from original 80-120mm to 10-20mm, so that settlement of the outdoor step member harmonizes with that of the main building, using is unaffected, and bad social impact is avoided.
