“空中足球场”罩蓬网架施工

CONSTRUCTION OF SPACE TRUSS AWNING OFOVERHEAD FOOTBALL GROUND

足球场观众席上的罩蓬多为高空悬挑式网架结构，而土建施工单位一般施工时均将观众席与主体同步施工，这就给后期的网架安装带来一定难度。本文结合悬挑３０ｍ的网架罩蓬，采用“推进式”吊装法进行施工的实例，介绍一种新的特定条件下的网架施工方法。

Abstract Most awnings of stadiums are cantilever space truss structures and the construction units generally build the main body and the seat platforms simultaneously, which brings certain difficulties to the later on erection of the space truss. In this paper, a case study on a 30m cantilever awning, which was hoisted in the propelling way, was carried out to introduce a new space truss construction method under specific conditions.
