胜帆GRG安装工艺
Shengfan GRG installation process

 

一、GRG吊顶安装
吊顶安装主要通过螺杆连接,螺杆不小于8厘米 ,但螺杆连接不宜过高,如果吊顶完成面与楼板高度超过1米,最后另行焊接转换层转,换层的高度如果超过2米,就必须做双层钢架,钢架转换层必须考虑空间跨度,跨度过大的转换层应加大钢材型号以降低下垂指标。转换层做好后最好放置几天时间,让钢材的自然下垂到位后再进行GRG安装。安装吊顶GRG时可根据经验值把吊顶中部的水平适当调到5mm左右,GRG板块安装好后由于受力作用钢架还会再次下降,但系数不大,所以通过提高中部水平来解决。由于GRG的特性易变型,并且弹性比较好,所以安装好后的GRG板块之间须用螺丝连接。

一、GRG ceiling installation
Ceiling installation mainly through the screw connection, the screw is not less than 8 cm, but the screw connection should not be too high, if the ceiling finish and floor height of more than 1 meter, and finally another welding conversion layer, the height of the layer if more than 2 meters, Double steel frame, steel frame conversion layer must take into account the space span, the span of the conversion layer should be increased to increase the steel model to reduce the sag index.After the conversion layer is best to put a few days after the time, so that the natural sagging steel in place after the GRG installation.When installing the ceiling GRG, the level of the middle part of the ceiling can be adjusted to about 5mm according to the experience value. After the GRG plate is installed, the steel frame will fall again after the steel plate, but the coefficient is not big, so it is solved by raising the middle level.As the GRG characteristics of the variable type, and the elasticity is better, so the installed GRG plate must be connected with a screw.

二、墙面安装(与GRC干挂法安装一样)
二、Wall mounting (same as GRC dry installation)



三、接缝处理:
       1.嵌缝膏调配:拉法嵌缝石膏+短纤(玻璃纤维)+缓凝剂+水
       2.步骤:安装缝用嵌缝膏填实(可分两次填实),然后用玻纤网将接缝处贴好(玻纤网必须用水泡足方可使用),贴完玻纤网后表面用防水腻子批平后方可进入下一表面处理工序。
三、Seam processing :
       1. Cracked paste deployment: Rafa caulking plaster + staple fiber (glass fiber) + retarder + water
       2. Step: install the seam with caulking paste filled (can be divided into two fill), and then use the fiberglass mesh will be posted at the seam (fiberglass mesh must be used only before the bubble), paste the finished glass After the surface with a waterproof putty approved before entering the next surface treatment process.




四、GRG表面处理:
      1.乳胶漆
      2.氟碳漆
      3.金箔,银箔,铜箔
  4.胶衣
四、GRG Surface Treatment:
       1.Latex paint
       2. Fluorocarbon paint
       3. Gold foil, silver foil, copper foil
       4. gel coat




五、钢材计算公式(换算比重)
      1.无缝钢管:(外径—壁厚)*壁厚*0.02456
    2.方钢:周长*壁厚*0.00785
    3.等边角铁:(边宽*2—边厚)*边厚*0.00795
    4.不等边角铁:(长边宽+短边宽—边厚)*边厚*0.00795
      5.槽钢 工字钢:0.00785*腿厚【高+e(腿宽—腰厚)】
      6.钢板:7.85*厚度
五、Calculation formula for steel (conversion ratio)
       1. Seamless steel pipe: (OD - wall thickness) * Wall thickness * 0.02456
       2. Square steel: Perimeter * Wall thickness * 0.00785
       3. equilateral angle: (width * 2 side thick) * side thick * 0.00795
       4. Unequal angle iron: (long side width + short side width - side thick) * side thick * 0.00795
       5. Channel I-beam: 0.00785 * Leg thickness [high + e (leg width - waist thickness]
       6. Steel plate: 7.85 * Thickness
