不同内模布置方式的现浇空心板的对比试验

Contrastive experimental research on the cast-in-situ reinforced concrete hollow slab with embedded filler of different arrangement mode

试验研究了不同内模布置方式的现浇钢筋混凝土空心板,结果表明顺孔板和横孔板承载能力无明显差异,在板底受拉钢筋屈服前这两种板的变形相差不大,钢筋屈服后横孔板变形明显大于顺孔板。

In the paper, two cast-in-situ reinforced concrete hollow slabs with the embedded filler of the different arrangement mode are tested. The results show that there is no obvious difference in supporting capacity between the hollow slab with lengthways embedded fillers and the one with the transverse embedded fillers;there is little difference in the deformation of the two slabs before the bottom steel bar of the slab bends; and after the steel bar bends, the extent of the＂ transverse slab deformation is greater than that＇of the lengthways slab deformation.
