摘 要:为了实现商业建筑消防的快速化设计,提高设计人员的工作效率,文章介绍了通过对Auto CAD二次开发,将商业建筑的施工图进行模型简化。通过对简化后的建筑施工图平面消防相关信息的提取与赋值后,结合消防设计防火规范相关规定,对建筑消防设计中的重要数值进行智能化计算,在经模型验证后发现智能化计算结果满足设计需求和国家规范规定。最终分析认为该智能化计算可以辅助设计快速计算相应指标,为消防审查部门、设计师和开发商均带来工作效率的提升。

Abstract:In order to realize the rapid design of the commercial building fire protection and improve the working efficiency of designers, how to simplify the construction drawing of a commercial building through the secondary development of AutoCAD is introduced in this paper. Based on the extraction and assignment of fire-related information of the simplified architectural construction drawing plane, the important values in the fire-fighting design of the building are calculated intelligently in combination with the relevant provisions of the fire-fighting design code. After the model verification, it is found that the results of the intelligent calculation meet the design requirements and the national regulations. According to the final analysis, the intelligent calculation may assist the design to quickly calculate the corresponding indexes, so as to improve the work efficiency of fire inspection departments, designers and developers.

隨着建筑质量终身责任制的全面落实,消防设计无疑成为了建筑专业施工图设计中最为重要的,也是消耗时间和精力最为巨大的内容。分析建筑火灾发生和造成严重后果的原因,其中很重要的一点是在建筑设计的过程中,建筑防火指标选择仅仅是满足规范要求,没有针对建筑中火灾的易发处和不利点做出针对性的调整。随着我国城市发展速度的加快,新建了大量的商业建筑。商业建筑的疏散宽度,是消防审查部门关注的重点指标之一。在新建项目规模庞大的情况下,高精度的核查与计算设计单位提供的图纸尤为耗时耗力,考虑到设计单位在选择折算系数时,通常选择最小系数进行折算,而非根据建筑的性质与规模进行调整,选择合适的系数就使得整个工作量更加庞杂。……
