濟(jì)南彩鋼板房作為現(xiàn)代社會(huì)一種靈活、簡單、便捷的新型活動(dòng)房，其優(yōu)點(diǎn)和便利性是非常明顯的。這種簡易房屋的房體主要承重框架是鋼結(jié)構(gòu)，墻體四周采用夾層彩鋼板作為墻體，這樣的簡易房屋具有建造快而簡單，拆除方便，而且還能結(jié)合使用和再利用，非常。
As a flexible, simple and convenient new activity room in modern society, Jinan color steel plate house has obvious advantages and convenience. The main load-bearing frame of this simple house is steel structure, and the sandwich color steel plate is used as the wall around the wall. This simple house has the advantages of fast and simple construction, convenient demolition, combined use and reuse, and is very environmentally friendly.
鋼結(jié)構(gòu)是彩鋼房屋的主體框架，所以鋼結(jié)構(gòu)的穩(wěn)定性直接決定了移動(dòng)房屋的穩(wěn)定性，一旦鋼結(jié)構(gòu)變形就會(huì)變得非常不安 全。為了避免鋼結(jié)構(gòu)的變形，人們常用以下四種方法:
Steel structure is the main frame of color steel house, so the stability of steel structure directly determines the stability of mobile house. Once the steel structure is deformed, it will become very unsafe. In order to avoid the deformation of steel structure, people often use the following four methods:

1、夾具固定方法:用非常剛性的夾具夾住焊 接件，用力控制變形，然后焊 接，這種方法稱為夾具固定方法。
1. Fixture fixing method: clamp the weldment with a very rigid fixture, control the deformation with force, and then weld. This method is called fixture fixing method.
在焊 接過程中，焊 接件內(nèi)部的膨脹力和收縮力受夾緊力的限 制，可以明顯降低變形。但是，這種方法不適用于需要較少內(nèi)應(yīng)力的構(gòu)件，因?yàn)楹?接部分內(nèi)應(yīng)力較大。
In the welding process, the expansion force and contraction force inside the weldment are limited by the clamping force, which can significantly reduce the deformation. However, this method is not suitable for components requiring less internal stress, because the internal stress of welded parts is larger.
2、反向變形法:焊 接前應(yīng)根據(jù)焊 接金屬構(gòu)件來判斷構(gòu)件。當(dāng)焊 接冷卻時(shí)，會(huì)出現(xiàn)變形方向和收縮量，焊 接部位會(huì)提前向相反方向彎曲或傾斜。焊 接后，由于自身的收縮和變形，它會(huì)回到預(yù)定的形狀位置。防止焊 接變形，降低焊 接應(yīng)力。
2. Reverse deformation method: the component should be judged according to the welded metal component before welding. When the welding is cooled, there will be deformation direction and shrinkage, and the welding part will bend or tilt to the opposite direction in advance. After welding, due to its own shrinkage and deformation, it will return to the predetermined shape and position. Prevent welding deformation and reduce welding stress.
3、采用定位控制方法:在構(gòu)件焊 接前，用許多焊點(diǎn)對(duì)焊 接部位或周圍的焊點(diǎn)進(jìn)行定位，同時(shí)也在焊縫的兩側(cè)施加重量，這種方法稱為定位控制方法。
3. Using positioning control method: before component welding, many welding points are used to position the welding position or surrounding welding points, and weight is also applied on both sides of the weld. This method is called positioning control method.
4、焊 接順序法:正確安排焊 接順序是防止焊 接變形的有效方法。焊 接變形的規(guī)律是:焊縫引起的變形較大，各焊縫引起的變形一般不能相互抵消，產(chǎn)生的變形方向與焊縫引起的變形方向一致。
4. Welding sequence method: the correct arrangement of welding sequence is an effective method to prevent welding deformation. The rule of welding deformation is: the deformation caused by weld is large, the deformation caused by each weld can not offset each other, and the deformation direction is consistent with that caused by weld.
