1、安装版块沒有边肋与立肋，气压和气体涨力下产生形变
1. The installation plate has no side ribs and vertical ribs, and deformation occurs under air pressure and gas expansion
这类形变状况多发生在选用金属复合板为设定的幕墙铝板上。目前许多建筑小区业主为了更好地节约成本，采用不靠谱的生产商。生产厂家为获较高盈利，版块生产加工不安裝边肋，中肋，只将铝朔板叠成盒状，立即用螺丝拧在架构上，版块间隙抹胶密封性即使竣工。那样幕墙铝板的版块抗压强度达不上规定，版块在正负极气压功效下造成向里向外的疲乏性挠度值形变，使表面规格提高。
This kind of deformation mostly occurs on the curtain wall aluminum plate set with metal composite plate. At present, many building community owners adopt unreliable manufacturers in order to better save costs. In order to obtain higher profits, the manufacturer does not install side ribs and middle ribs in the production and processing of the plate. Only the aluminum plastic plate is stacked into a box shape, and immediately screw it on the structure with screws. The gap between the plates is coated with glue, and the sealing is even completed. In that way, the compressive strength of the plate of the curtain wall aluminum plate can not meet the requirements, and the plate will cause the fatigue deflection value deformation inward and outward under the effect of positive and negative pressure, so as to improve the surface specification.
体现非常明显的朝阳面的幕墙铝板，因为施工技术是选用保溫暖墙的方式将版块间隙所有用胶密封性严密，表面与构造墙间距里的气体在阳光照射效用下提温，版块在气体涨力功效下导致向外形变。
The aluminum plate of curtain wall reflecting the very obvious sunrise surface, because the construction technology is to use the way of thermal insulation and warm wall to seal all the plate gaps tightly with glue. The gas in the distance between the surface and the structural wall increases the temperature under the effect of sunlight, and the plate changes to the shape under the effect of gas expansion.
2、版块与幕墙铝板构造架构固定不动，内应力没法放松造成形变
2. The plate and the aluminum plate structure of the curtain wall are fixed, and the internal stress cannot be relaxed, resulting in deformation
铝合金板幕墙铝板在时节气温差异比较大地域，在春初秋后温度较低的时节，这时候的太阳光照射热效率很强，尤其是色调较深的铝合金板提温比较大，铝合金板在不一样环境温度下，每米长短上的热变形值区别比较大。幕墙铝板架构在里面，太阳危害较差，铝合金板与架构较大时可造成80℃之上的温度差，在铝合金板规格过大时便会发生很大的线形澎涨差。假如幕墙铝板版块构造选用压边，将铝合金板用螺丝固定不动在架构上的构造，将导致铝合金板表面的内应力没法释放出来，驱使表面妥协，在气体功效下向外发生形变状况。

Aluminum alloy plate curtain wall aluminum plate has large temperature difference in seasons. In the season of low temperature after early spring and autumn, the solar radiation thermal efficiency is very strong, especially the temperature rise of aluminum alloy plate with deep color is relatively large, and the thermal deformation value of aluminum alloy plate per meter is quite different under different ambient temperatures. The aluminum plate structure of curtain wall is inside, and the solar harm is poor. When the aluminum alloy plate and the structure are large, it can cause a temperature difference above 80 ℃, and a large linear surge difference will occur when the specification of aluminum alloy plate is too large. If the blank holder is selected for the structure of the aluminum plate plate of the curtain wall, and the aluminum alloy plate is fixed on the structure with screws, the internal stress on the surface of the aluminum alloy plate cannot be released, driving the surface to compromise and deform outward under the effect of gas.
3、控制面板与边肋安装时造成地应力形变
3. In situ stress deformation caused by the installation of control panel and side rib
有一些生产商为处理铝合金板版块表面的内应力形变，尤其是控制面板选用金属复合板时，在零部件版块的附近加了一圈边肋框，从生产工艺流程上是控制面板在刨槽机上按版块压边规格刨槽折边成盒状。
In order to deal with the internal stress and deformation on the surface of aluminum alloy plate, some manufacturers, especially when the metal composite plate is selected for the control panel, add a ring of edge rib frame near the parts plate. From the production process flow, the control panel planes the groove and folds the edge into a box shape according to the plate blank holder specification on the grooving machine.
另一条线是将边肋铝型材按版块必须规格断开拼装成边肋框。随后边肋框装进盒状控制面板，用拉铆钉将两体固定不动。在工作中当场常常发觉因控制面板刨槽折边有误差，边肋铝型材拼装成框有误差，两体相互配合常常发生并不是框小便是板折边规格过大。为保施工期，不费料，通常强制安装，导致表面造成安装地应力，并不是边肋形变便是表面受力形变。这类版块在溫度和气体澎涨大作下造成向外的形变状况。
The other line is to disconnect and assemble the edge rib aluminum profile into an edge rib frame according to the specifications of the plate. Then install the side rib frame into the box control panel and fix the two bodies with pull rivets. During the work, it is often found that there is an error in the groove folding of the control panel, and there is an error in the assembly of the edge rib aluminum profile into the frame. The two bodies often cooperate with each other. It is not the frame that urinates, but the specification of the plate folding is too large. In order to ensure the construction period and cost no materials, the installation is usually forced, resulting in the installation in-situ stress on the surface, which is either the edge rib deformation or the surface stress deformation. This kind of plate causes outward deformation under the action of temperature and gas surge.
