Report from our correspondent (reporter Feng Bao) as of the end of April, by triumpher steel construction, the construction of the Lishui stadium project completed a task node, curtain wall keel installed.

幕墙龙骨采用矩形钢管制作，从体育馆外部整体上看，其外壁钢结构网格呈碗形，玻璃幕墙嵌入菱形网格中并相契合。每个菱形网格内，玻璃幕墙又分为9个小格。由于碗形外壁在形状上为变化的弧形，每个菱形幕墙龙骨均分成为有一定折角的上下两个三角形，并且自下向上每层的折角均不同，同时相互交叉的各层龙骨在外观上又要保持线条上连续变化，因而大大增加了龙骨的安装难度。项目部技术人员与施工队紧密配合，仔细测量每种网格的详细外形尺寸，在对数据统计分析的基础上做出深化详图，先在胎架上精确做好样品试装合格后再成批加工、安装，最终保证了幕墙龙骨的顺利施工。

Curtain wall keel for the use of rectangular steel tube is made, from the outside of the stadium on the whole, the outer wall of the steel grid structure form a bowl, glass curtain wall embedded rhombus grid and fit. Within each diamond grid, the curtain wall is divided into 9 small lattices.. Due to the outer wall of the bowl in the shape change of arc, each lozenge curtain wall keel sharing become certain bending angle of the two triangles and bottom to each layer of the folded angle are different, while the cross cutting layers of the keel in appearance but also to maintain continuous lines of change, thus greatly increasing the difficulty in the installation of the keel. Project department technical staff and construction team closely and carefully measured every grid detailed dimensions, in based on the analysis of statistical data to make further detail, first in fetal frame accurate well samples passing the test equipment and batch processing, installation, and ultimately ensure the smooth construction of the curtain wall keel.

5月份，丽水体育馆将开始屋面预应力索的张拉施工。

May, Lishui gymnasium will start the construction of the roof cable tension.
