摘　　要：研究的混凝土砌体创新点在于砌块带有销键,且砌体由薄层砂浆砌筑而成,大大提高了砌块砌体的抗剪性能。该研究砌块具有保温隔热和抗倾覆的特性,符合节能环保要求,可用于各类建筑。该研究对8组72个试件进行抗剪试验,分析销键、砂浆类型等因素对砌体抗剪强度的影响,并为编写新规范提供理论依据。该研究定量分析了薄层砂浆和销键等因素提高砌体抗剪强度的幅度。The innovation of concrete masonry is that the building block has the pin key, and the masonry is made of thin mortar, which greatly improves the shear performance of the block masonry.The research block has the characteristics of thermal insulation and earthquake resistance,which meets the requirements of building energy conservation,and is suitable for urban and new rural construction.If there is a block pin,mortar type,block type （wall） to affect the masonry shear strength factor of 8 groups of 72 specimens of shear test, analysis of effects of several factors on shear strength of masonry model, and to provide a theoretical basis for the preparation of new specification.This study quantitatively analyzes the factors that increase the shear strength of masonry, such as thin layer mortar and pin bond.
