重庆西南技术商城五星级宾馆大堂楼盖为椭圆形,以井字梁中空承重。以下对梁的施工作一个介绍。屋面内椭圆(见图1)面积390m~2,中空高度12.6m,搭满堂架作业。模板为组合钢模板,因井字梁截面较高(1450mm),为确保侧向刚度,在距梁底高300mm、1000mm处设两道φ10对拉螺杆,沿水平方向按间距300mm布置。脚手架和模板示意见图2。由于脚手架要承受较大荷载
The lobby of the five-star hotel in the Southwest Technology Mall in Chongqing has an elliptical shape and is hollow and bearable. The following is an introduction to the work of beams. The oval in the roof (see Figure 1) has an area of 390m~2 and a hollow height of 12.6m. The template is a composite steel formwork. Because the cross-section of the girder beam is relatively high (1450mm), in order to ensure the lateral rigidity, two φ10 pairs of pull-screws are set at a height of 300mm and 1000mm from the bottom of the beam and are arranged along the horizontal direction at a distance of 300mm. Scaffolding and template shown in Figure 2. Due to the scaffolding being subjected to higher loads
