摘要：为解决国内蒸压加气混凝土墙板生产成本高、生产工艺复杂等一系列问题，提出装配式配纤维格栅ALC砌块墙板。采用四分点加载法对2块素墙板和2块配纤维格栅的墙板进行抗弯试验，验证该墙板在实际工程中的可行性。通过改变拼接形式以及配纤维格栅面积进行墙板优化，研究了相应优化形式对墙板破坏形式、挠度和抗弯承载力的影响。素墙板与配纤维格栅墙板均发生脆性破坏；极限破坏荷载均已超过墙体自重的1.5倍；且配纤维格栅面积越大，抗弯承载力越大，挠度越小，墙板抗弯性能越好。选取环向包裹2道纤维格栅的墙板作为砌块墙板优化类型，该墙板的抗弯性能符合JG/T 169—2016《建筑隔墙用轻质条板通用技术要求》的要求。

Abstract：In order to solve a series of problems such as high production cost and complex production technology of autoclaved aerated concrete wallboard in China，the paper puts forward the fabricated fiber grid ALC block wall board，and carries on the bending test to it and verifies the feasibility of the wall board in the actual project. The four-point loading method is used to test the bending resistance of two plain wall panels and two wall panels with fiber grid. By changing the splicing form and distributing fiber grid area to optimize the wall board，the influence of the corresponding optimization form on the failure form，deflection and flexural bearing capacity of the wall board is studied. The ultimate failure load is 1.5 times of the wall weight，and the larger the fiber grid area，the greater the flexural bearing capacity and the smaller the deflection，the better the flexural performance of the wall board. The wall board with two fiber grid wrapped around is selected as the optimization type of block wallboard，which meets the requirements of standard JG/T 169—2016"General technical requirements of lightweight panel used for building partition".
