东莞篮球中心幕墙工程采用复杂的三向空间曲面形状,单层索网结构。索网预应力的控制是玻璃幕墙施工的关键,考虑玻璃幕墙的安装要求及索张拉对整个结构的影响,研制用于该施工技术的节点接驳件,严格控制拉索下料长度及节点标示。环向拉索采用分步分级进行张拉,并通过运用有限元分析软件和对张拉过程应力监测,确保了工程质量。
Dongguan Basketball Center curtain wall project uses a complex three-dimensional space surface shape, single-layer cable network structure. Control of cable network prestress is the key to the construction of glass curtain wall. Considering the installation requirements of glass curtain wall and the influence of cable tension on the whole structure, the node connecting piece for the construction technology is developed and the length and node of cable pull are strictly controlled Marked. Ring to the cable step by step grading, and through the use of finite element analysis software and stress monitoring of the tension process to ensure the quality of the project.
