基于风洞试验下大面积金属屋面系统防漏与防风揭工艺

The Leakproof and Windproof Uncovering Technology of the Metal Roofing System with Large Area Based on Wind Tunnel Test

金属屋面系统历来以其美观、质轻而广受公共建筑设计者青睐,但正是由于其质轻的特点而使得风荷载对其影响成为主要因素之一,尤其是大面积金属屋面系统的防风揭技术处理成为其施工的重难点。通过天津滨海国际机场T2航站楼的金属屋面系统施工,介绍了对其防风揭施工技术创新应用,并根据风洞试验数据,有针对性地对风吸力较大部位进行加强处理。

Metal roofing system has always been popular with its beautiful and light appearance to public building designer. But it is because of the characteristics of the light made of the effect of the wind load on one of the main factors, especially the windproof uncovering technology of metal roofing system with the large area, which becomes the difficult point of the construction. In this paper, through the metal roofing system construction of Binhai International Airport T2 terminal in Tianjin, the authors introduce construction technology innovation to its application about windproof uncovering. And according to the wind tunnel test data, this paper is targeted to strengthen the parts of wind suction larger.
