1、安裝版塊沒有邊肋與立肋，氣壓和氣體漲力下產(chǎn)生形變
1. The installation plate has no side ribs and vertical ribs, and deformation occurs under air pressure and gas expansion
這類形變狀況多發(fā)生在選用金屬復(fù)合板為設(shè)定的幕墻鋁板上。目前許多建筑小區(qū)業(yè)主為了更好地節(jié)約成本，采用不靠譜的生產(chǎn)商。生產(chǎn)廠家為獲較高盈利，版塊生產(chǎn)加工不安裝邊肋，中肋，只將鋁朔板疊成盒狀，立即用螺絲擰在架構(gòu)上，版塊間隙抹膠密封性即使竣工。那樣幕墻鋁板的版塊抗壓強(qiáng)度達(dá)不上規(guī)定，版塊在正負(fù)極氣壓功效下造成向里向外的疲乏性撓度值形變，使表面規(guī)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.
體現(xiàn)非常明顯的朝陽面的幕墻鋁板，因?yàn)槭┕ぜ夹g(shù)是選用保溫暖墻的方式將版塊間隙所有用膠密封性嚴(yán)密，表面與構(gòu)造墻間距里的氣體在陽光照射效用下提溫，版塊在氣體漲力功效下導(dǎo)致向外形變。
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、版塊與幕墻鋁板構(gòu)造架構(gòu)固定不動(dòng)，內(nèi)應(yīng)力沒法放松造成形變
2. The plate and the aluminum plate structure of the curtain wall are fixed, and the internal stress cannot be relaxed, resulting in deformation
鋁合金板幕墻鋁板在時(shí)節(jié)氣溫差異比較大地域，在春初秋后溫度較低的時(shí)節(jié)，這時(shí)候的太陽光照射熱效率很強(qiáng)，尤其是色調(diào)較深的鋁合金板提溫比較大，鋁合金板在不一樣環(huán)境溫度下，每米長(zhǎng)短上的熱變形值區(qū)別比較大。幕墻鋁板架構(gòu)在里面，太陽危害較差，鋁合金板與架構(gòu)較大時(shí)可造成80℃之上的溫度差，在鋁合金板規(guī)格過大時(shí)便會(huì)發(fā)生很大的線形澎漲差。假如幕墻鋁板版塊構(gòu)造選用壓邊，將鋁合金板用螺絲固定不動(dòng)在架構(gòu)上的構(gòu)造，將導(dǎo)致鋁合金板表面的內(nèi)應(yīng)力沒法釋放出來，驅(qū)使表面妥協(xié)，在氣體功效下向外發(fā)生形變狀況。

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、控制面板與邊肋安裝時(shí)造成地應(yīng)力形變
3. In situ stress deformation caused by the installation of control panel and side rib
有一些生產(chǎn)商為處理鋁合金板版塊表面的內(nèi)應(yīng)力形變，尤其是控制面板選用金屬復(fù)合板時(shí)，在零部件版塊的附近加了一圈邊肋框，從生產(chǎn)工藝流程上是控制面板在刨槽機(jī)上按版塊壓邊規(guī)格刨槽折邊成盒狀。
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.
另一條線是將邊肋鋁型材按版塊必須規(guī)格斷開拼裝成邊肋框。隨后邊肋框裝進(jìn)盒狀控制面板，用拉鉚釘將兩體固定不動(dòng)。在工作中當(dāng)場(chǎng)常常發(fā)覺因控制面板刨槽折邊有誤差，邊肋鋁型材拼裝成框有誤差，兩體相互配合常常發(fā)生并不是框小便是板折邊規(guī)格過大。為保施工期，不費(fèi)料，通常強(qiáng)制安裝，導(dǎo)致表面造成安裝地應(yīng)力，并不是邊肋形變便是表面受力形變。這類版塊在溫度和氣體澎漲大作下造成向外的形變狀況。
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.
