贵州是世界上最大的喀斯特连续带,又是一个煤炭资源丰富的省份。本研究根据这种自然环境所产生的特殊材料设计了一种既保温隔热,又能体现地域性特征的粉煤灰砌块石板墙,使粉煤灰和喀斯特石材成为了真正的绿色建材。首先按照《夏热冬冷地区居住建筑节能设计标准》(JGJ 134-2010),生产一种能保温隔热的粉煤灰夹芯砌块,然后在粉煤灰夹芯砌块上外挂石板,让石板和砌块组成一个具有一定宽度的通风空间,形成粉煤灰砌块与石板的夹缝墙体,利用热压原理排发热量。通过理论分析和对温度、自然通风等模拟结果的分析可知,粉煤灰和喀斯特石材在外墙的地域性特征和保温隔热方面具有良好的效果。
Guizhou is the largest karst belt in the world and a province rich in coal resources. Based on the special materials produced in this kind of natural environment, this study designed a fly-ash block slate wall which not only insulates heat and insulates but also reflects the regional characteristics, making the fly ash and karst stone become the real green building materials. First of all, according to “Design Standard for Energy Efficiency of Residential Buildings in Hot Summer and Cold Winter Zone” (JGJ 134-2010), a kind of fly ash sandwich block which can be heat-insulated and heat-insulated is produced, then the slate is flocculated on the fly-ash sandwich block, Let the slate and blocks form a ventilation space with a certain width to form a nip wall between the fly-ash blocks and the slate, and use the principle of hot pressing to discharge heat. Through theoretical analysis and analysis of the simulation results of temperature and natural ventilation, it can be seen that the fly ash and karst stone have good effect on the regional characteristics of exterior wall and thermal insulation.
