彩钢板屋面和彩钢围挡板的安装

彩钢板屋面主要采用50mm厚的彩钢围挡板，顶板长度根据工程需要和运输要求而定。安装采用扣件连接，用自攻螺钉固定在檩条上。安装的压型钢板应搭接严密。屋面板波纹应垂直于屋脊轴线。应使用测量仪器预先放置一条直线，以确定整个板的对齐。

彩钢围挡板在大型建筑工程中，为缩短施工时间，可采用吊车将成捆的屋面板直接从汽车吊到屋架上。对于较长的面板，建议采用抱杆和吊绳的方法。对于中小型工程，可以用手卸料，然后用绳子将单块屋面板绑好，再用人力将屋面板拉到屋架上，然后固定安装。本工程采用人工搬运施工。
为保护 彩钢板屋面压型 彩钢围挡板表面，保证施工人员的安全，必须用干燥、清洁的手套触摸屋面板压型钢板表面。不要在粗糙面上拖拽压型钢板或在屋面板表面拖拽压型钢板，工具等其他东西不能在屋面板表面拖拽压型钢板。
沿屋面板纵向行走时，应在其凹槽内行走。横向沿屋面板行走时，尽量靠近或踩在屋顶支撑点上。一般来说，负荷应均匀分布在脚底，而不是脚跟或脚趾。穿软底平底鞋，不要穿条纹槽底鞋，这样容易嵌入小石块。刚拆下的屋面板压型钢板表面有油污。你表演时要非常小心。施工现场不可避免地要在屋面板表面切割压型钢板，但应注意保护其他钢板，因为电锯切割会产生金属颗粒。如需在其他屋面板表面的压型钢板上切割时，应在切割屋面板表面的压型钢板与下屋面板表面的压型钢板之间放置保护物，屋面板表面的压型钢板面朝下。同时，最好在电锯上放一把金属切割刀。与金刚石砂轮切割相比，该方法能产生较少的金属颗粒，切口光滑。
一般情况下，安装屋顶和防水板时，自攻螺栓、钻孔、手锯、链锯或其他操作会在屋顶的相邻区域留下金属碎片。这些碎片和其他杂物（铆钉、钉子、螺丝灯等）必须尽快从屋顶、防水板、排水沟等处清除。把这件事做完。尤其是整个屋顶安装完毕后，不能免除。忽略这项工作会氧化金属碎片，导致表面形成污渍。当以铁、铜、铅等为基料的物品与铝锌板表面接触，并同时暴露在潮湿或冷凝水中时，会造成铝锌镀层的损坏，并导致钢板从表面腐蚀。
将屋面板表面的压型钢板吊到表面安装时，请确保屋面板表面的所有压型钢板面朝上，所有搭接边面朝待安装的屋顶。否则，不仅会翻转屋面板表面的压型钢板，还会翻转屋面板表面的压型钢板。屋面板表面压型钢板束应靠近檩条支撑点或放在檩条支撑点上，不得放在檩条跨内。在固定第一块板之前，确保其位置垂直、方正，并将其正确放置在与其他建筑构件相关的位置上。

The roof i mainly made of 50 mm thick sandwich panel, and the length of the roof panel depends on the engineering needs and transportation requirements. The installation shall be connected with snap fastener and fixed on purlin with self tapping screw. The profiled steel plate installed shall be tightly overlapped. The roof panel ripple shall be vertical to the ridge axis. A straight line shall be pre placed with measuring instrument to determine the alignment of the overall plate.

In large-scale construction projects, in order to shorten the time, bundles of roof panels can be hoisted directly from the truck to the roof frame by crane. For longer panels, it is recommended to use the method of carrying pole and lifting rope. For small and medium-sized projects, unloading can be done by hand, then the single roof panel can be tied with ropes, and then the roof panel can be pulled onto the roof frame by manpower, and then fixed and installed. The project adopts manual handling construction.
In order to protect the surface of profiled steel plate on the roof panel and ensure the safety of construction personnel, dry and clean gloves must be used to touch the profiled steel plate on the roof panel surface. Do not drag the profiled steel plate on the rough surface or the profiled steel plate on the roof panel surface, and other things such as tools cannot drag on the profiled steel plate surface on the roof panel surface.
When walking along the roof panel longitudinally, walk in its groove. When walking along the roof panel transversely, try to be close to or step on the roof support point. Generally, the load should be evenly distributed on the sole of the foot, not on the heel or toe. Wear soft soled flat shoes instead of striped groove soled shoes, which are easy to embed small stones. The surface of profiled steel plate on the roof panel just removed is greasy. Be very careful when you act. It is inevitable to cut profiled steel plate on the surface of roof panel at the construction site, but attention should be paid to protect other plates, because the cutting of electric saw will produce metal particles. If it is necessary to cut it on the profiled steel plate on the surface of other roof panels, a protective object shall be placed between the profiled steel plate on the surface of the cut roof panel and the profiled steel plate on the surface of the lower roof panel, and the profiled steel plate on the surface of the roof panel shall face down. At the same time, it is better to put a metal cutting knife in the electric saw. Compared with diamond wheel cutting, this method can produce less metal particles, and the incision is smooth.
In general roof and flashing installation, self tapping bolts, drilling holes, hand saws, chainsaws, or other operations will leave metal debris on the adjacent areas of the roof. These debris and other sundries (rivets, nails, screw lights, etc.) must be removed from the roof, flashing, gutters, etc. as soon as possible. Make this work the end of the day. Especially after the whole roof is installed, it can not be exempted. Neglecting this work will oxidize the metal debris and lead to the formation of stains on the surface. When the articles based on iron, copper, lead and so on contact with the surface of the aluminum zinc plate, and are exposed to moisture or condensed water together, it will cause the damage of the aluminum zinc coating, and lead to the corrosion of the steel plate from the surface.
When the profiled steel plate on the roof panel surface is hoisted to the surface for installation, please make sure that all the profiled steel plates on the roof panel surface face up, and all the lap edges face the roof to be installed. Otherwise, it will not only flip the profiled steel plate on the surface of the roof panel, but also turn the profiled steel plate on the surface of the roof panel. The bundle of profiled steel plates on the surface of roof panel shall be placed close to or on the purlin support point, but not in the purlin span. Before fixing the first plate, ensure its position is vertical and square, and correctly place it on the position related to other building components.
When the first roof panel surface profiled steel plate is fixed in place, a continuous alignment shall be drawn at the lower end of the roof. This line and the first roof panel surface profiled steel plate will become the conductor, which is convenient for the quick installation and correction of the subsequent roof panel surface profiled steel plate. Then find out that each roof area needs to be tested in a certain section during installation. The method is to measure the width of the profiled steel plate on the surface of the fixed roof panel once at the top and bottom respectively to ensure that there is no movement and sector. In some stages, such as half installation, the distance from the top and bottom of the profiled steel sheet on the surface of the fixed roof panel to the far side of the roof or the finished line shall be measured to ensure that the profiled steel sheet on the surface of the fixed roof panel is parallel to the finished line. If you need to adjust, you can place and fix each plate in the future and make sector adjustment slightly. Until the profiled steel plate on the surface of roof slab reaches flatness. According to the construction drawings, the roof panels of grid structure shall be stacked on the material stacking yard in a complete set, and the complete roof panels of grid structure shall be hoisted to the design position and fixed along with the hoisting.
