第六章   网架屋面板安装
Chapter6.  Roof sheeting installation 
1、屋面板的基本知识
1. Basic knowledge of roof sheeting
该工程所选用的屋面板板型为840型,其断面形状。如下图所示:
Roof sheeting for this project is type 840 plates, with its section showed below:

其特点及基本要求如下:
   The characteristic and basic requirements as following:
   1.1、所有板均有小边及大边之分。
All the plates can be divided into small edge and big edge.   
   1.2、板与板侧面搭接时只允许小边压大边。
It is only allowed to press small edge on the big edge when plate and side plate laps over.
   1.3、板使用自钻自攻螺钉与屋面檩条固定,自攻钉打在波峰上。
Fasten the plates and the roof purlin by self-drilling screw with tapping screw, fix the tapping screw on the wave crest. 
   1.4、使板在檩条上固定所使用的主要工具为手枪钻及内六方套筒。
The main tools are portable drill and hexagonal sleeve to fix plates on the purlin. 
   1.5、屋面采光板与屋面板板型相同,打板时自攻钉下增加马鞍件,以加强采光板连接强度。如下图所示:
 Roof translucent panel type is same as roof sheeting, increase saddle-shaped cushion while fixing roof sheeting to strengthen connection strength of translucent panel. See figure below:
   1.6、打板时应用拉线的办法保证自攻钉在檩条上成一条直线。
Align the self-tapping screw with wire on the purlin during roof installation.
2、屋面板的堆放和吊装
   Stacking and erection of roof sheeting
   屋面板的堆放原则是:
Roof sheeting stacking principal:
2.1、尽量靠近安装位置,方便板材的取用(或吊装),减少运输距离。
 Try to be close with the installation location, easy to fetch plates (or erection), decrease transportation distance.
   2.2、成捆板材堆放时应使一端垫高利于排水,如图所示:
Cushion one end higher during stacking the bundled plates, as the following figure:
2.3、成捆板材吊装时应使用两根吊带起吊,吊带间距约为板长的2/3。  
Use 2 slings to start erection during the erection of the bundled plates; the sling distance is about 2/3 of plates. 
3、安装前的准备工作
   Preparing work before installation
3.1安装屋面板的工具较为简单,主要是手枪钻及内六方套筒。另外还要准备滑轮、尼龙绳等吊板用具。
Roof sheeting installation tool is quite simple, mainly use portable drill and internal hexagonal sleeve. And also pulley, nylon rope and plate hanger should be prepared. 
3.2人员分组:上部安装4人,拉板及抬板4人共计每组8人,以四个小组安装为宜,安装时应做好充分的安全防护工作。
Group division: 4 people for top surface installation,4 people for pulling and lifting plates,8 people in total for each group,4 groups would be effective, safety protection work should be well guaranteed during installation.
4、第一块屋面板安装:
   First roof sheeting installation
4.1、根据设计图纸定出第一块屋面板的位置线,即可安装第一块板,将板的波边与基准线对齐,使板的波峰与轴线垂直,用自攻钉将板与檩条固定,如下图所示。
Set the location line of the first roof sheeting based on design drawing, then the first sheet can be installed, align the wave edge with the baseline, the sheet wave crest be vertical with the axis, use self-tapping screw to fix the sheet and purlin. See figure below:
注意事项:
Notice:
(1)、打板时每道檩条均应打钉。
Every purlin should be nailed during roof sheeting installation.
(2)、板最上端的一道檩条暂不打钉,待上好第二层板再打。
purlin on top edge of sheeting is temporarily not nailed, nail on second sheet when the first sheet completes.
   (3)、每一波峰均应打钉。    
Every wave crest should be nailed.
 
4.2、屋面板安装方向是每一层从网架一边开始安装,层与层自下往上安装,纵横搭接线应横平竖直成一线。
Roof sheeting installation direction is from one side to start installation of every layer, installation direction is from down to top of every layer, vertical and horizontal overlapped line should be vertical and transversal with each other.
4.3、屋面板对集中荷载较敏感,因此屋面施工时,施工人员不得聚集在一起,以避免集中荷载导致面板变形破坏。
Roof sheeting is very sensitive about concentrated load, construction workers should not get together to work during construction to avoid roof sheeting deion caused by concentrated load. 
4.4、屋面板安装后应尺寸准确无误,表面清洁干净,无可察觉的凹凸和折线,纵横搭接均成直线,接缝均匀整齐,严密无翘曲。
After installation, the roof sheeting dimension should be strictly correct, surface should be clean, without concave-convex and broken line, vertical and horizontal overlap should be straight, connection joint should be uniform and neat, tight and without bucking.
    5、安装第一层屋面板
以第一块板为基准,第二块板的小波边压住第一块板的大波边,辅设第二块板,用自攻钉与檩条固定,完成第二块板的安装。以此类推即可完成第一层屋面板的全部安装 (屋面采光板的安装同屋面板一样,不同的是打自攻钉时应用马鞍件加强)。每打完4~5块板时应检查保证波峰与轴线垂直。
Take the first sheet as basic standard, small wave edge of second sheet presses big wave edge of first sheet, use self-tapping to fix purlin, so that the second sheet installation can be finished, use the same measure to finish the first layer roof sheet installation (translucent panel installation takes the same measure with roof sheet, the difference is using saddle cushion to tap screw), check it while 4~5 sheets are completed to ensure the crest be vertical with axis.
6、第二层及以上屋面板的安装方法如下图所示。
Installation of second layer and above roof sheeting is shown below.
参照第一层屋面板的安装方法,但必须注意:
Based on the first layer roof sheet installation measure, but to notice:
(1)、安装前应在第一层板的上端贴防水双面胶带,详见设计图。
Water-proof double sticky tape should be applied on the top edge of the first layer before installation, see details in design drawing.
(2)、第二层板与第一层板的搭接长度应符合设计图的要求。
Overlapping length between first layer sheet and second layer sheet should be according to the design drawing requirement.
