N式砌块通过对砌块块形的改进实现了在砌筑砌体时孔、肋完全对齐,N式砌块在半灌孔和全灌孔时可以同缝砌筑。研究了同缝砌筑的半灌孔N式砌块砌体受压性能,了解了N式砌块砌体在同缝砌筑下的破坏形态及破坏机理。试验结果,同缝砌筑的半灌孔N式砌块砌体的抗压强度平均值比普通砌块的抗压强度平均值高出30%左右,分析表明,其强度提高的主要原因是孔洞对齐和砌块块体的约束作用。给出了N式砌块砌体同缝抗压强度平均值的计算公式,与试验结果吻合良好。
N-block through the improvement of the block block to achieve masonry when masonry holes, ribs completely aligned, N-type block in the semi-full hole and full irrigation can be the same slot masonry. The compression performance of the semi-perforated N-block masonry with the same structure was studied, and the failure mode and failure mechanism of the N-block masonry under the same structure were studied. The test results show that the average compressive strength of N-block masonry with semi-perforated holes in masonry buildings is about 30% higher than the average compressive strength of common blocks. The analysis shows that the main reason for the increase in strength is that the holes Alignment and block block constraints. The formula for calculating the average compressive strength of the same block in N-block masonry is given, which is in good agreement with the experimental results.
