本文对钢丝网岩棉夹芯复合板(简称GY板)的横向挠曲强度,轴向中心受压强度、轴向偏心受压强度、GY板隔墙及GY板承剪墙的剪切强度作了大量的试验研究,阐明了其强度特征和破坏模式,然后提出相应的设计分析理论,并与试验结果相比较以证明其可行性。试验研究和理论分析表明:在各种受力情况下,所设计的GY板不仅能够保证其整体作用,而且充分发挥了各组成材料的强度,达到了最优材料配制。强度研究表明,根据实际条件所设计的GY板已能胜任一到二层快装永久性房屋的主要构件。
This paper deals with the transverse flexural strength, axial center compressive strength, axial eccentric compressive strength, shear strength of GY panel partition wall and GY panel shear wall of steel mesh rock wool sandwich panel (referred to as GY panel). A large number of experimental studies have clarified their strength characteristics and failure modes, and then proposed corresponding design analysis theories, and compared with the experimental results to prove its feasibility. Experimental studies and theoretical analysis show that under various stress conditions, the designed GY plate can not only ensure its overall function, but also fully exert the strength of each component material and achieve the optimal material preparation. Strength studies have shown that GY boards designed based on actual conditions have been able to outperform the main components of any one-to-two-story fast-installed permanent housing.
