为了获得一种喷涂保温材料-原竹组合楼板抗弯性能,完成了1组共计2个试件的试验研究.通过试验观察对比各级荷载作用下组合楼板和原竹骨架楼板挠度的发展情况,探讨楼板的破坏过程、破坏形式及破坏机理,考虑竹材与喷涂保温材料之间的组合效应,获得组合楼板的抗弯承载力和抗弯刚度.研究结果表明:原竹与物料组合效应较好,组合楼板能够满足抗弯承载力和挠曲变形的要求,可以作为土建楼板使用;试验组合楼板在正常使用阶段的整体抗弯刚度约为原竹骨架楼板的17倍,其极限承载力约为原竹骨架楼板的2倍.
In order to obtain a kind of sprayed insulation material - the original bamboo composite slab flexural performance, completed a group of 2 specimens of a total of experimental study.According to the experimental observation and comparison of the load at all levels of composite slab and original bamboo skeleton floor deflection development, The failure process, failure mode and failure mechanism of the floor slab are discussed, and the combined effect between bamboo and sprayed insulation material is considered to obtain the flexural capacity and flexural rigidity of the slab.The results show that the combination effect of raw bamboo and material is better, Composite floor can meet the requirements of flexural capacity and flexural deformation, can be used as a civil floor; test composite floor in normal use phase of the overall bending stiffness of about 17 times the original bamboo skeleton floor, the ultimate bearing capacity of about the original Bamboo skeleton floor 2 times.
