对4块足尺页岩陶粒混凝土双向叠合板进行了静力堆载试验,并对其变形特征、破坏形态和裂缝开展情况进行了分析;同时对2块足尺页岩陶粒混凝土单向叠合板进行了静力堆载试验,以研究叠合面的滑移特征。结果表明:半普通-半陶粒混凝土叠合板和全陶粒混凝土叠合板均具有良好的整体性和较高的刚度及承载力,能够作为结构楼板使用;同时通过对单向板板侧应变的分析,叠合面不会出现滑移。
Four full-scale shale cemented-concrete two-way laminated plates were subjected to static loading test, and their deformation characteristics, failure modes and crack development were analyzed. Two full-length shale ceramsite concrete unidirectional The composite slab was subjected to static loading test to study the slip characteristics of the laminated surface. The results show that the semi-ordinary - semi-ceramsite concrete composite plates and full ceramic concrete composite plates have good integrity and high stiffness and bearing capacity, can be used as a structural floor; at the same time through the unilateral plate side of the strain Analysis, overlapping surface will not slip.
