沙盘因其显著的直观性及展示性越来越多地被用于展览馆、售楼中心等建筑。沙盘电路复杂,主要材质多为高分子聚合物,且一般放置在人员密集场所,因此,火灾危险性较大。本文从沙盘工艺、沙盘材质、沙盘放置区域的防火设计等方面分别提出建议,以降低沙盘着火概率,控制沙盘火灾蔓延范围和保护人员疏散安全。 Sand table because of its significant intuitive and display more and more used in exhibition halls, sales centers and other buildings. Sand table circuit complexity, the main material mostly polymer, and is generally placed in a crowded place, therefore, a greater risk of fire. In this paper, suggestions are put forward respectively from sand table technology, sand table material and fire protection design of sand table to reduce the probability of sand table fire, control the scope of sand table fire and protect the evacuation safety.
