摘要:近年来随着国内居民生活水平的提高，越来越多的建筑设计师们追求造型新颖的弧形结构方式。而对于弧形建筑内的变曲率弧形钢管管道的施工质量、施工效率、观感质量等方面的问题一直以来饱受业界单位的关注。随着建筑业BIM技术应用的推广与迅猛发展，我们利用BIM技术与物联网技术相结合，总结形成了一套基于BIM技术的变曲率弧形管道工厂化预制，现场扫码快速定位拼装的施工工艺，该技术具有定位精准、成型效果好、施工质量可靠、提升工效、降低施工成本等特点，适用于建筑物外观造型复杂，管路走向受楼体形状限制，公称直径200mm以下的变曲率弧形钢管管道的施工，通过在相关工程中的实际应用取得了良好的效果和一定的经济效益。

Abstract: Recently, with the improving domestic residential living standard, increasing numbers of architectural designers are pursuing the arc structural mode to make the building stand out of the background. However, for the construction of the variably curved steel pipes in such curved buildings, its construction quality, constructive efficiency and visual quality are all problems widely concerned by the industry units. With the rapid promotion and popularity of the BIM industry, by utilizing the BIM and Internet technology, we summarizes a set of the variably curved steel pipe construction workshop of prefabricating off-site and code-based fast positioning and assembling on-site, which is well-performed in positioning, molding, construction quality, efficiency improving and construction cost reduction. The construction workshop is especially suitable for the construction of buildings with complex appearance style, pipelines restricted by the building shape, or curved pipes with nominal diameter under 20mm. Applications in related construction projects has proven that the workshop is efficient and economically benefit.
