［摘要］針對(duì)采用傳統(tǒng)的平面測(cè)量和空間定位方法對(duì)造型復(fù)雜、異形曲面多的建筑幕墻定位和放樣復(fù)雜、困難的問(wèn)題，以成都大魔方演藝中心幕墻系統(tǒng)軸線放樣和幕墻安裝過(guò)程為背景，首先提出了雙層控制網(wǎng)、軸網(wǎng)法向線的測(cè)量放樣方法，采用該方法在不降低精度的同時(shí)大大簡(jiǎn)化了此類建筑幕墻測(cè)量和定位的時(shí)間和工序；其次提出了采用“模具輔助測(cè)量、平尺輔助安裝”的工裝系統(tǒng)對(duì)幕墻進(jìn)行安裝，提高了安裝精度，縮短了安裝時(shí)間。所提的系列方案極其適用于具有曲面外觀的建筑測(cè)量放樣和異形幕墻系統(tǒng)的安裝，可為類似工程幕墻系統(tǒng)的定位和安裝提供一定的參考。

Abstract:It is complex and difficult to locate and set out this kind of building curtain wall by using the traditional plane measurement and spatial positioning methods. In view of the above problems, the curtain wall system axis setting-out and curtain wall installation process of Chengdu Large Magic Cube Performing Arts Center was taken as the background,  and the measurement method of double-layer control network and grid normal line were put forward, which greatly simplified the time and process of measurement and positioning of this kind of building curtain wall without reducing the accuracy. The installation method of “mold auxiliary measurement and flat ruler auxiliary installation” was proposed for the curtain wall to improve the installation accuracy and shorten the installation time. The proposed series of schemes are very suitable for building measurement and setting-out of curtain walls with curved surface appearance and installation of special-shaped curtain wall system, providing certain basis for the positioning and installation of similar engineering curtain wall system.

Keywords:Chengdu Large Magic Cube Performing Arts Center; special-shaped curtain wall; measurement and setting-out; grid positioning; curtain wall installation
