Consequently , the precast components don ’ t need any interim falseworks to be supported in the mid - span as bottom forms when the laminated concrete lay is being placed . furthermore , to form two - way slabs , the transverse steels can be arranged through the rectangular cores in the ribs of the precast slabs as needed . it makes the construction of composite two - way slabs easier and more feasible , practical , and suitable to introduce and apply to the building construction on a large area 由于預制構件具有剛度大和承載力高的特點,施工時以預制構件作為樓板底模無需設置跨中臨時支撐;同時還能通過預制構件板肋預留的長方形孔布置橫向受力鋼筋實現樓板的雙向配筋,使預應力雙向疊合樓板的施工簡單易行,更適合于大面積的推廣應用,具有較大的工程應用價值。
The experimental result indicate that the working characters of the test floor slab is typically two - way obviously , the floor slab that is reinforced two - way by setting transverse steels through the rectangular cores in the ribs of the precast slabs , has excellent bulking property , high bearing capacity , cracking resistance and so on 試驗研究表明,試驗樓蓋在加載過程中呈現了明顯的雙向受力特征; pk預應力疊合樓蓋通過在預制構件板肋預留長方形孔穿置橫向鋼筋實現雙向配筋具有良好的整體性能,還具備承載力高和抗裂性能良好等特點。
