Abstract: During the construction of the three-glass two-cavity curved glass curtain wall, the secondary keel usually adopts mechanical bending arc, and the main keel and the T-shaped submerged plate are usually connected by channel steel. These two types of construction will lead to excessive installation errors and low pass rates for one installation. In order to improve the pass rate of one installation, the curved mold is used to bend the secondary keel in this paper, and the angle steel with two round holes in different directions is used to connect the main keel and the T-type submerged plate, and the results show that the pass rate of the first installation is increased from 85.6% to 96.2%, and the construction cost is greatly saved. This improved construction method has the advantages of good construction quality, short construction cycle and high economic benefits, which provides reference and reference for the subsequent construction of curved glass curtain wall.

Key words: three-glass two-cavity glass curtain wall, one pass rate, secondary keel bending arc, mold, connector

摘要： 三玻两腔曲面玻璃幕墙施工过程中次龙骨通常采用机械弯弧,主龙骨与T型埋板通常采用槽钢连接。这两种施工会导致安装误差过大、一次安装合格率偏低的情况。为提高一次安装合格率,采用弧形模具对次龙骨进行弯弧,同时采用开两个不同方向长圆孔的角钢连接主龙骨与T型埋板,结果表明一次安装合格率由85.6%提高到96.2%,同时大大节省了施工费用。该施工方法具有施工质量好、施工周期短、经济效益高等优点,为后续曲面玻璃幕墙施工提供了借鉴和参考。
