为了解决目前墙体内外保温的问题,结合配筋砌块砌体的优势,本文提出了一自保温配筋砌块砌体体系。本文对6组18个自保温砌块灌孔砌体抗压试件进行了抗压试验以及相应的理论研究,了解了自保温砌块灌孔砌体的开裂强度、极限强度、变形性能与破坏特征等内容。并根据两种计算模型推导了自保温砌块灌孔砌体的抗压强度计算式,研究结果表明,砌块强度和计算值基本吻合。同时通过试验统计分析,保温层设置并未使砌体提前开裂。本文还通过对规范公式和现有公式进行优化调整,提出了适用于自保温砌块灌孔砌体的本构关系模型与弹性模量计算式。
In order to solve the problem of thermal insulation inside and outside the wall at present, combined with the advantages of reinforced block masonry, a self-insulation reinforced block masonry system is proposed in this paper. In this paper, six groups of 18 self-thermal insulating block grouting masonry compression test specimens and the corresponding theoretical study to understand the self-insulating block grouting masonry cracking strength, ultimate strength, deformation and damage Features and so on. According to two calculation models, the formula of compressive strength of self-insulation block grouting masonry is deduced. The result shows that the strength and calculated value of block are basically in agreement. At the same time through the test statistical analysis, insulation layer setting did not make the masonry cracked in advance. In this paper, through the optimization and adjustment of the standard formula and the existing formula, the constitutive model and elastic modulus calculation formula of self-insulation block perforated masonry are proposed.
