在中空阳光板安装工程中极重要的是边缘的紧固，必须注意以下两点：
Whether dry assembly or wet assembly, whether horizontal, vertical and inclined installation. It is very important to tighten the edge in the installation of hollow sunplate. The following two points should be paid attention to:
在连接型材中或在镶框的镶槽中必须留出有效的空间以便板材受膨胀和受载位移。
Effective space must be set aside in connection profiles or in frame grooves for expansion and load displacement of the sheet.
中空阳光板的线性热膨胀系数是7×10m/m.k，假山制作 不锈钢铸件 铝箔真空袋 七孔梅花管 hdpe硅芯管 液压钢坝 PVC软管 飞行激光打标机 沥青保温泵即温度每升高1℃，1m×1m板顺着长度方向各膨胀0.075mm，用户须根据工程所在地分四季温差，算出安装间隙的数据:如北方地区，最高温度为40℃，最低温度为-30℃，1m×1m的板材安装预留间隙为0.07×70=4.9mm
The linear thermal expansion coefficient of the hollow solar panel is 7 *10m/m.k, i.e. every temperature rise of 1 C, the 1m *1m plate expands 0.075mm along the length direction. Users must calculate the installation gap data according to the four seasons temperature difference of the project location: for example, in the northern region, the highest temperature is 40 C, the lowest temperature is - 30 C, and the reserved room for 1m *1m plate installation The gap is 0.07*70=4.9mm
