rectangular core meaning in Chinese

矩形铁心

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
由于预制构件具有刚度大和承载力高的特点,施工时以预制构件作为楼板底模无需设置跨中临时支撑;同时还能通过预制构件板肋预留的长方形孔布置横向受力钢筋实现楼板的双向配筋,使预应力双向叠合楼板的施工简单易行,更适合于大面积的推广应用,具有较大的工程应用价值。
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
试验研究表明,试验楼盖在加载过程中呈现了明显的双向受力特征; pk预应力叠合楼盖通过在预制构件板肋预留长方形孔穿置横向钢筋实现双向配筋具有良好的整体性能,还具备承载力高和抗裂性能良好等特点。
