提出了内置芯柱保温夹层组合砖砌体,为研究其抗压性能,进行了4组不同材料和不同构造措施的保温夹层砖砌体受压性能试验研究。第一组为粘土砖试件,第二组为再生混凝土砖试件,第三组为粘土砖夹砌粉煤灰砌块试件,第四组为再生混凝土砖夹砌粉煤灰砌块试件;每组4个试件,分别为普通砌体、内置方木芯柱砌体、内置方钢管混凝土芯柱砌体、内置圆钢管混凝土芯柱砌体;共计16个试件。基于试验,研究了不同构造作法对保温夹层砖砌体受压性能的影响,对比分析了各试件的承载力、损伤破坏特征和受压变形过程,给出了内置芯柱保温夹层砖砌体受压承载力计算公式。研究表明,内置芯柱保温夹层砖砌体与普通砌体相比,受压承载力和延性均明显提高。
In order to study its compressive strength, four different types of insulating material and different structural measures of the thermal insulation sandwich brick masonry compression test were studied. The first group is clay brick specimen, the second group is regenerated concrete brick specimen, the third group is clay brick masonry fly ash brick specimen, and the fourth group is recycled concrete brick masonry fly ash brick test Pieces; each set of 4 specimens, namely ordinary masonry, built-in square wooden core column masonry, built-in square steel tube concrete core column masonry, built-in CFST core column masonry; a total of 16 specimens. Based on the experiments, the influence of different construction practices on the compression behavior of thermal insulating sandwich brick masonry was studied, and the bearing capacity, damage characteristics and compression deformation process of each specimen were analyzed. Compressive bearing capacity calculation formula. The research shows that compared with the ordinary masonry, the built-in column insulation sandwich brick masonry obviously increases the compressive bearing capacity and ductility.
